Does genetic diversity protect host populations from parasites? A meta-analysis across natural and agricultural systems
<p>If parasites transmit more readily between closely related hosts, then parasite burdens should decrease with increased genetic diversity of host populations. This important hypothesis is often accepted at face value - notorious epidemics of crop monocultures testify to the vulnerability of host populations that have been purged of diversity. Yet the relationship between genetic diversity and parasitism likely varies across contexts, differing between crop and non-crop hosts and between experimental and natural host populations. Here, we used a meta-analytic approach to ask if host diversity confers protection against parasites over the range of contexts in which it has been tested.</p> <p>We synthesized the results of 102 studies, comprising 2,004 effect sizes representing a diversity of approaches and host-parasite systems. Our results validate a protective effect of genetic diversity, while revealing significant variation in its strength across biological and empirical contexts. In experimental host populations, genetic diversity reduces parasitism by ~20% for non-crop hosts and by ~50% for crop hosts. In contrast, observational studies of natural host populations show no consistent relationship between genetic diversity and parasitism, with both strong negative and positive correlations reported. This result supports the idea that, if parasites preferentially attack close relatives, the correlation of genetic diversity with parasitism could be positive or negative depending upon the potential for host populations to evolve in response to parasite selection. Taken together, these results reinforce genetic diversity as a priority for both conservation and agriculture and emphasize the challenges inherent to drawing comparisons between controlled experimental populations and dynamic natural populations.</p>
Identifying diagnostic genetic markers for a cryptic invasive agricultural pest: a test case using the apple maggot fly, Rhagoletis pomonella (Diptera: Tephritidae)
Insect pests destroy ~15% of all USA crops, resulting in losses of $15 billion annually. Thus, developing cheap, quick and reliable methods for detecting harmful species is critical to curtail insect damage and lessen economic impact. The apple maggot fly, Rhagoletis pomonella (Diptera: Tephritidae), is a major invasive pest threatening the multibillion-dollar apple industry in the Pacific Northwest USA. The fly is also sympatric with a benign but morphologically similar and genetically closely related species, R. zephyria, which attacks non-commercial snowberry. Unambiguous species identification is essential due to a zero-infestation policy of apple maggot for fruit export. Mistaking R. zephyria for R. pomonella triggers unnecessary and costly quarantines, diverting valuable control resources. Here we develop and apply a relatively simple and cost-effective diagnostic approach using Illumina sequencing of double digest restriction-site associated DNA markers. We identified five informative single nucleotide polymorphisms (SNPs) and designed a diagnostic test based on agarose gel electrophoresis of restriction enzyme digested polymerase chain reaction amplification products (RFLPs) to distinguish fly species. We demonstrated the utility of this approach for immediate, one day species identification by scoring apple- and snowberry-infesting flies of known host plant identity, reared directly from 11 sites throughout Washington. However, if immediate diagnosis is not required, or hundreds to thousands of specimens must be assessed, then a direct Illumina-based sequencing strategy, similar to that used here for diagnostic SNP identification can be powerful and cost-effective. The genomic strategy we present is effective for R. pomonella and also transferable to many cryptic pests.
Data from: Making Brexit work for the environment and livelihoods: delivering a stakeholder informed vision for agriculture and fisheries
1. The UK's decision to leave the EU has far-reaching implications for agriculture and fisheries. To ensure the future sustainability of UK agricultural and fisheries systems, we argue that it is essential to grasp the opportunity that Brexit is providing to develop integrated policies that improve the management and protection of the natural environments, upon which these industries rely. 2. This article advances a stakeholder informed vision of the future design of UK agriculture and fisheries policies. We assess how currently emerging UK policy will need to be adapted in order to implement this vision. Our starting point is that Brexit provides the opportunity to redesign current unsustainable practices and can in principle deliver a sustainable future for agriculture and fisheries. 3. Underpinning policies with an ecosystem approach, with explicit inclusion of public goods provision, and social welfare equity were found to be central to the success of this endeavour. Recognition of the needs of, and innovative practices in, the devolved UK nations is also required as the new policy and regulatory landscape is established. 4. Achieving our proposed vision will necessitate drawing on best practice and creating more coherent and integrated food, environment and rural and coastal economy policies. Sustainable prosperity should and can form the core of future post-Brexit environmental policy thinking and our findings demonstrate the "bottom-up" and co-production approaches that will be key to the development of more environmentally sustainable agricultural and fisheries policies.
Data from: Factors influencing herpetofauna abundance and diversity in a tropical agricultural landscape mosaic
<p>Agricultural intensification and the associated factors, including land transformation, are among the major global threats affecting biodiversity especially herpetofauna. However, little information is available about how different factors shape herpetofauna species assemblages in agricultural landscape at different spatial scales from patch (125 – 250m) to the landscape (500 – 1000m).</p> <p>We assessed the diversity of amphibians and reptiles in areas under low and high degrees of agricultural intensification and explored different factors regulating diversity at different spatial scales using four sampling methods.</p> <p>Diversity and abundance of amphibians varied significantly between the two zones, but not for reptiles. Agricultural intensification Index (AII), calculated based on agrochemical use and area under agriculture at 250m scale, seemed to affect amphibians both at patch as well as at 500m and 1000m landscape scales. The AII influenced reptilian diversity only at patch and 500m scales. Vicinity of natural forest had a stronger influence on reptilian abundance. Semi-natural vegetation impacted herpetofauna diversities at larger spatial scales. The extent of water bodies influenced the reptilian abundance at 250m patch scale and amphibian abundance both at 250m and 1000m scale. Fallow lands affected only reptilian diversity at all spatial scales. Plantation affected amphibian at all scales but reptiles only at the landscape scale. Habitat heterogeneity regulated only amphibian diversity.</p> <p>These results highlight the fact that different patch and landscape-scale factors regulate the diversity of reptiles and amphibians differentially. Such scale specific information will crucially inform future conservation action for the herpetofauna in the agricultural landscape.</p>
Agricultural intensification and land use change: assessing country-level induced intensification, land sparing and rebound effect
<p><span><span><span><span><span><span><span><span><span><span><span>In the context of growing societal demands for land based products, crop production can be increased through expanding cropland or intensifying production on cultivated land. Intensification can allow sparing land for nature, but it can also drive further expansion of cropland, i.e. a rebound effect. Conversely, constraints on cropland expansion may induce intensification. We tested those hypotheses by investigating the bidirectional relations between changes in cropland area and intensity, using a global cross-country panel dataset over 1961-2016. We used a cointegration approach with additional tests to disentangle long and short-run causal relations between variables, and total factor productivity and yields as two measures of intensification. Over the long run we found support for the induced intensification thesis for low income countries. In the short run, intensification resulted in a rebound effect in middle-income countries, which include many key agricultural producers strongly competitive in global agricultural commodity markets. This rebound effect manifested for commodities with high price-elasticity of demand, including rubber, flex crops (sugarcane, palm oil and soybean), and tropical fruits. Over the long run, strong rebound effects remained for key commodities such as flex crops and rubber. Staple cereals such as wheat and rice manifested significant land sparing. In low-income countries, intensification driven by increases in total factor productivity was associated with a stronger rebound effect than yields increases. Agglomeration economies may drive yields increases for key tropical commodity crops. Our study design could allow addressing other complex long and short run causal dynamics in land and social-ecological systems.</span></span></span></span></span></span></span></span></span></span></span></p>
The super-rich and cropland expansion via direct investments in agriculture
<p>Cropland expansion represents an important cause of tropical deforestation, contributing to the loss of ecosystems' functions. Flex-crops (e.g., oil palm, soy, sugar cane) account for an increasing share of cropland and contribute significantly to carbon emissions and biodiversity loss. Various forms of inequality have been shown to impact on agricultural expansion, yet the effect of wealth concentration among the super-rich is understudied. Here I show how, over the period 1991-2014, the large amount of wealth in the hands of high net worth individuals (HNWI) stimulated foreign direct investments in agriculture in Latin America and South-East Asia. This, in turn, drove the expansion of flex-crops areas. The combination of these two effects implies that, a 1% increase in the wealth of HNWI generated an expansion of the flex-crops area share of up to 2.4-10%. The results point to the urgency of addressing wealth inequality to protect the remaining forests.</p>
Data from: Nitrous oxide (N2O) emissions from subsurface soils of agricultural ecosystems
Nitrous oxide (N2O) is a major greenhouse gas and cultivated soils are the most important anthropogenic source. N2O production and consumption are known to occur at depths below the A or Ap horizon but their magnitude in situ is largely unknown. At a site in SW Michigan USA we measured N2O concentrations at different soil depths and used diffusivity models to examine the importance of depth-specific production and consumption. We also tested the influence of crop and management practices on subsurface N2O production in 1) till vs. no-till, 2) a nitrogen fertilizer gradient, and 3) perennial crops including successional vegetation. N2O concentrations below 20 cm exceeded atmospheric concentrations by up to 900 times, and profile concentrations increased markedly with depth except immediately after fertilization when production was intense in the surface horizon, and in winter, when surface emissions were blocked by ice. Diffusivity analysis showed that N2O production at depth was especially important in annual crops, accounting for over 50% of total N2O production when crops were fertilized at recommended rates. At nitrogen fertilizer rates exceeding crop need, subsurface N2O production contributed 25-35% of total surface emissions. Dry conditions deepened the maximum depth of N2O production. Tillage did not. In systems with perennial vegetation, subsurface N2O production contributed <20% to total surface emissions. Results suggest that the fraction of total N2O produced in subsurface horizons can be substantial in annual crops, is low under perennial vegetation, appears to be largely controlled by subsurface nitrogen and moisture, and is insensitive to tillage.
Data from: Comparative landscape genetics of two frugivorous bats in a biological corridor undergoing agricultural intensification
Agricultural intensification in tropical landscapes poses a new threat to the ability of biological corridors to maintain functional connectivity for native species. We use a landscape genetics approach to evaluate impacts of expanding pineapple plantations on two widespread and abundant frugivorous bats in a biological corridor in Costa Rica. We hypothesize that the larger, more mobile Artibeus jamaicensis will be less impacted by pineapple than the smaller Carollia castanea. In 2012 and 2013, we sampled 735 bats in 26 remnant forest patches surrounded by different proportions of forest, pasture, crops and pineapple. We used 10 microsatellite loci for A. jamaicensis and 16 microsatellite loci for C. castanea to estimate genetic diversity and gene flow. Canonical correspondence analyses indicate that land cover type surrounding patches has no impact on genetic diversity of A. jamaicensis. However, for C. castanea, both percentage forest and pineapple surrounding patches explained a significant proportion of the variation in genetic diversity. Least-cost transect analyses (LCTA) and pairwise G″st suggest that for A. jamaicensis, pineapple is more permeable to gene flow than expected, while as expected, forest is the most permeable land cover for gene flow of C. castanea. For both species, LCTA indicate that development may play a role in inhibiting gene flow. The current study answers the call for landscape genetic research focused on tropical and agricultural landscapes, highlights the value of comparative landscape genetics in biological corridor design and management and is one of the few studies of biological corridors in any ecosystem to implement a genetic approach to test corridor efficacy.
Increasing agricultural habitat reduces solitary bee offspring number and weight in apple orchards through reduced floral diet diversity and increased fungicide risk
<p>1. Threats to bee pollinators such as land use change, high pesticide risk, and reduced floral diet diversity are usually assessed independently, even though they often co-occur to impact bees in agroecosystems.</p> <p>2. We established populations of the non-native mason bee O. cornifrons at 17 NY apple orchards varying in proportion of surrounding agriculture and measured floral diet diversity and pesticide risk levels in the pollen provisions they produced. We used path analysis to test the direct and indirect effects of different habitats, diet diversity, and pesticide risk on emergent female offspring number and weight.</p> <p>3. Our results showed that high proportions of agricultural habitat surrounding bee nests indirectly reduced the number of female offspring produced, by reducing floral diet diversity in pollen.</p> <p>4. When proportion agriculture surrounding bee nests was high, bees collected increased proportions of Rosaceae in their pollen provisions, which marginally (0.05<p<0.1) increased fungicide risk levels in pollen, which, in turn, marginally reduced female offspring weight. In contrast, female offspring weight increased as proportion surrounding open habitat (wildflowers, grassland, pasture) increased, but this effect was not influenced by proportion Rosaceae or fungicide risk levels in pollen.</p> <p>5. Synthesis and Applications: To promote healthy O. cornifrons populations in apple, we must maintain floral resource diversity and open habitats, while reducing fungicide risk levels and agricultural habitats. More broadly, our results show that land use change, in the form of increasing agricultural habitat, can negatively impact bee populations in agroecosystems indirectly through multiple, simultaneous threats. We must strive to understand these complex interactions between simultaneous threats to maintain healthy bee populations in agroecosystems, where we rely on them for pollination.</p>
Data from: The molecular phylogenetics of Trachymyrmex ants and their fungal cultivars provide insights into the origin and co-evolutionary history of 'higher-attine' ant agriculture
The fungus‐growing ants and their fungal cultivars constitute a classic example of a mutualism that has led to complex coevolutionary dynamics spanning c. 55–65 Ma. Of the five agricultural systems practised by fungus‐growing ants, higher‐attine agriculture, of which leaf‐cutter agriculture is a derived subset, remains poorly understood despite its relevance to ecosystem function and human agriculture across the Neotropics and parts of North America. Among the ants practising higher‐attine agriculture, the genus Trachymyrmex Forel, as currently defined, shares most‐recent common ancestors with both the leaf‐cutter ants and the higher‐attine genera Sericomyrmex Mayr and Xerolitor Sosa‐Calvo et al. Although previous molecular‐phylogenetic studies have suggested that Trachymyrmex is a paraphyletic grade, until now insufficient taxon sampling has prevented a full investigation of the evolutionary history of this group and limited the possibility of resolving its taxonomy. Here we describe the results of phylogenetic analyses of 38 Trachymyrmex species, including 27 of the 49 described species and at least 11 new species, using four nuclear markers, as well as phylogenetic analyses of the fungi cultivated by 23 species of Trachymyrmex using two markers. We generated new genetic data for 112 ants (402 new gene sequences) and 95 fungi (153 new gene sequences). Our results corroborate previous findings that Trachymyrmex, as currently defined, is paraphyletic. We propose recognizing two new genera, Mycetomoellerius gen.n. and Paratrachymyrmex gen.n., and restricting the continued use of Trachymyrmex to the clade of nine largely North American species that contains the type species [Trachymyrmex septentrionalis (McCook)] and that is the sister group of the leaf‐cutting ants. Our fungal cultivar phylogeny generally corroborates previously observed broad patterns of ant–fungus association, but it also reveals further violations of those patterns. Higher‐attine fungi are divided into two groups: (i) the single species Leucoagaricus gongylophorus (Möller); and (ii) its sister clade, consisting of multiple species, recently referred to as Leucoagaricus Singer 'clade B'. Our phylogeny indicates that, although most non‐leaf‐cutting higher‐attine ants typically cultivate species in clade B, some species cultivate L. gongylophorus, whereas still others cultivate fungi typically associated with lower‐attine agriculture. This indicates that the attine agricultural systems, which are currently defined by associations between ants and fungi, are not entirely congruent with ant and fungal phylogenies. They may, however, be correlated with as yet poorly understood biological traits of the ants and/or of their microbiomes.
Converting conventional agriculture to poplar bioenergy crops: soil chemistry
<p>Woody bioenergy is a viable source of alternative energy; however, questions remain on how purpose-grown bioenergy feedstock production management impact surface soil chemistry. In order to understand the soil processes under poplar (<i>Populus spp.</i>) trees and adjacent agricultural sites, surface (0-15 cm) soil samples were collected from four northwestern United States locations over a four-year period. Initial and final surface soil samples were analyzed for various soil chemical parameters, including organic matter, pH, cation exchange capacity and nutrient concentrations. Fields selected to compare poplar and agricultural management initially differed in some key soil chemical parameters. Many soil chemical parameters changed over time and the magnitude of change often depended on location; however, initial differences between management types within any one location did not change over time for most soil chemical variables. Consistent in-location differences between management types over time show poplar did not alter soil chemical parameters relative to agricultural management during the study period. Together all observations indicate that little of the overall soil chemistry was impacted by introduction of poplar in the traditionally agricultural fields.</p>
Data from: Agricultural land-use history and restoration impact soil microbial biodiversity
<ol> <li>Human land uses, such as agriculture, can leave long-lasting legacies as ecosystems recover. As a consequence, active restoration may be necessary to overcome land-use legacies; however, few studies have evaluated the joint effects of agricultural history and restoration on ecological communities. Those that have studied this joint effect have largely focused on plants and ignored other communities, such as soil microbes.</li> <li>We conducted a large-scale experiment to understand how agricultural history and restoration tree thinning affect soil bacterial and fungal communities within longleaf pine savannas of the southern United States. This experiment contained 64 pairs of remnant (no history of tillage agriculture) and post-agricultural (reforested following abandonment from tillage agriculture >60 years prior) longleaf pine savanna plots. Plots were each 1-ha and arranged into 27 blocks to minimize land-use decision making biases. We experimentally restored half of the remnant and post-agricultural plots by thinning trees to reinstate open-canopy savanna conditions and collected soils from all plots five growing seasons after tree thinning. We then evaluated soil bacterial and fungal communities using metabarcoding.</li> <li>Agricultural history increased bacterial diversity but decreased fungal diversity, while restoration increased both bacterial and fungal diversity. Both bacterial and fungal richness were correlated with a range of environmental variables including aboveground variables like leaf litter and plant diversity, and belowground variables such as soil nutrients, pH, and organic matter, many of which were also impacted by agricultural history and restoration.</li> <li>Fungal and bacterial community compositions were shaped by restoration and agricultural history resulting in four distinct communities across the four treatment combinations.</li> <li>Past agricultural land use left persistent legacies on soil microbial biodiversity, even over half a century after agricultural abandonment and after intensive restoration activities. The impacts of these changes on soil microbe biodiversity could play important roles in the functioning of ecosystems following agricultural abandonment and during restoration.</li> </ol>
Data from: Farmer preferences for conservation incentives that promote voluntary phosphorus abatement in agricultural watersheds
Financial incentives are commonly used to promote voluntary adoption of agricultural best management practices (BMPs), but little is known about farmer preferences among alternative incentives. Using experimental procurement auctions, we evaluate how different conservation incentives affect farmer willingness to adopt BMPs that reduce phosphorus (P) runoff, a major driver of harmful algal blooms in Lake Erie. We rank incentives (e.g., payment, BMP insurance, tax credit, and certification price premium) by the cost per pound of P runoff reduction. Payments and tax credits that target high impact areas of the watershed are more cost-effective than untargeted price premiums for product certification. Farmers demand higher payments for contracts offering BMP insurance (i.e., protection against yield loss from BMP use) due to uncertainty about how the program will be implemented and the reliability of indemnities, as well as anticipated transaction costs associated with the program. Understanding farmer preferences for different types of conservation incentives is critical to design agri-environmental programs that engage more farmers and cost-effectively enhance ecosystem services.
Data from: Agricultural pastures challenge the attractiveness of natural saltmarsh for a migratory goose
1. Broad-scale land conversions and fertilizer use have dramatically altered the available staging area for herbivorous long-distance migrants. Instead of natural land, these birds rely increasingly on pastures for migratory fuelling and stopover, often conflicting with farming practices. To be able to predict and manage birds' future habitat use, the relative advantages and disadvantages of natural (e.g. saltmarsh, intertidal) versus anthropogenic staging sites for foraging need to be understood. 2. We compared the migratory staging of brent geese on saltmarsh and pasture sites in spring. Food quality (nitrogen and fibre content), intra-specific antagonistic behaviour, and body weight were quantified at nearby sites in simultaneous seasons. Individuals were tracked with high-resolution GPS and accelerometers to compare timing of migration and time-budgets during fuelling. 3. On pastures, birds rested more and experienced higher ingestion rates, similar or superior food quality and reduced antagonistic interactions than on saltmarsh. 4. Brent geese using fertilized grasslands advanced their fuelling and migration schedules compared to those using saltmarsh. Pasture birds reached heavy weights earlier, departed sooner, and arrived in the Arctic earlier. 5. Intertidal mudflats were frequently visited by saltmarsh birds during the day, and available food there (algae, some seagrass) was of higher quality than terrestrial resources. Availability of intertidal resources was an important factor balancing the otherwise more favourable conditions on pastures relative to saltmarsh. 6. Policy implications: Disadvantages of longer foraging effort, more antagonistic interactions and delayed fuelling schedules on traditional saltmarshes may cause a trend of geese exchanging this traditional niche in favour of pastures, especially in a warming climate that requires advancement of migratory schedules. However, the high quality of intertidal forage allows it to complement terrestrial foraging, potentially removing the incentive for habitat switches to pastures. The relatively high quality of green algae and seagrass, and birds' remarkable preference for these resources when available, provides a key for managers to create landscapes that can sustain this specialist's intertidal lifestyle. To keep natural habitats attractive to staging geese with the purpose to prevent conflicts with farming practices, management actions should focus on conservation and restoration of saltmarsh and especially intertidal habitat.
Data and code for: Terrestrial eDNA survey outperforms conventional approach for detecting an invasive pest insect within an agricultural ecosystem
<p>Recent methodological advances permit surveys for terrestrial insects from the direct collection of environmental DNA (eDNA) deposited on vegetation or other surfaces. However, in contrast to well-studied aquatic applications, little is known about how detection rates for such terrestrial eDNA-based surveys compare with conventional survey methods. <i>Lycorma delicatula</i>, the spotted lanternfly, is an emerging invasive insect in eastern North America, and a significant ecological and economic pest of forested and agricultural systems, especially grapes. During fall 2019 we conducted two rounds of paired eDNA and visual surveys for spotted lanternflies within 48 plots at 12 vineyards in New Jersey, USA. We compared detection probabilities within a multimethod occupancy modeling framework and used the results to extrapolate and inform survey design. The probability of detecting spotted lanternflies given presence in a plot was over two times higher for eDNA (84%) versus visual surveys (36%). In mid-September, lanternfly eDNA was detected at five plots in three vineyards while visual surveys revealed only a single individual in one plot. In early October, after dispersal of lanternflies into vineyards, lanternfly eDNA was detected in 12 plots within six vineyards compared with visual detections in six plots in two vineyards. Extrapolations based on detection and local-scale occupancy rates indicate that only five and 12 plots would have been needed to positively detect lanternfly presence with 95% confidence using eDNA in contrast to 14 and 29 plots with visual surveys alone, respective to survey rounds. Log-linear models revealed that visual counts of lanternflies were positively related to eDNA concentrations (R<sup>2</sup> = 71%). We provide some of the first quantitative evidence to support the enhanced sensitivity of terrestrial eDNA approaches compared with conventional methods. Such methods can augment efforts to combat invasive species through improved ability to delimit invasion fronts, identify satellite populations, and confirm local eradications.</p>
Open Access Journal Publishing in the Agricultural Sciences
<p>A survey was conducted on scholarly research communication and the prospects of Open Access (OA) to the scholarly research dissemination in India by Open Knowledge Society (OKS). The India's National Agricultural Research System (NARS) has been choosen as a case study for exploring the possibility of OA in publishing agricultural research. With over 90 Indian Council of Agricultural Research (ICAR) institutes and 42 agricultural universities, established by respective states at State level across the country, the Indian NARS, is one of the largest NARS of the world. The ICAR is the apex organization of Indian NARS coordinating the agricultural research and education of the country. The agriculture research output mainly comes from publicly funded projects, and many of the research centers and universities publish research journals (peer-reviewed) and magazines even in local languages apart from English. Beside, there are many professional societies in agriculture and related sciences publishing peer reviewed journals. However, majority of these journals are traditional print journals and thus are less visible to the outside world. In the country, the researchers cannot have the access to the published literature without the subscription to those journals and many of the libraries do not subscribe all the journals. From India, only four journals in the area of agriculture and animal sciences found in the Directory of Open Access Journals (DOAJ). Hence, it is felt that there is a tremendous potential for the research output to be made available to World with the OKS intervention and with the help of Open Journal System (OJS) software. OKS would like to bring this point forward and hope it can bring some change and create awareness about OA publishing in Agricultural research in India. The survey revealed that there are more than 100 journals which are being published in India on agricultural research by the universities, research centers and professional societies. However these publishers are not aware of the goodness of online open access publications. There is a need for creating awareness among the authors and publishers to embrace the latest Internet technologies for publication of research journals by persuasion campaigns. OKS is keen to promote Open Access Publishing (OAP) using OJS by helping institutions to setup their journals and also build an indexing system for Indian agricultural journals. The result would definitely help Indian researchers and the end user farmer community and also help other developing countries to improve their knowledge.</p>
