Data from: Nutrient enrichment increases invertebrate herbivory and pathogen damage in grasslands
<p>This dataset contains data on leaf damage by invertebrates and pathogens derived in a globally-distributed experiment manipulating nutrient addition (Nutrient Network). In total we estimated leaf damage on 153 plant taxa from twenty-seven grasslands worldwide, under ambient conditions and with experimentally elevated nitrogen and phosphorus. Additionally, we give MAT and MAP from WorldClim 1 for each site and percent cover for each plant species in the respective plot.</p>
Living on the edge: Predicting invertebrate richness and rarity in disturbance-prone aquatic–terrestrial ecosystems
<p>1. Temporal fluctuations in water levels cause the spatial extent of wet and dry habitats to vary in aquatic–terrestrial riverine ecosystems, complicating their biomonitoring. As such, biomonitoring efforts may fail to characterise the species that inhabit such habitats, hampering assessments of their biodiversity and implementation of evidence-informed management strategies.</p> <p>2. Relationships between the dynamic characteristics of aquatic-terrestrial habitats and their communities are well known. Thus, habitat characteristics may enable estimation of faunal assemblage characteristics such as taxonomic richness, regardless of in-channel conditions.</p> <p>3. We investigated whether indicators summarising habitat survey data can predict two metrics representing terrestrial invertebrate assemblages (e.g. taxa richness) in two aquatic–terrestrial habitats: exposed riverine sediments and dry temporary streams. We also compared the performance of unimetric and multimetric habitat indicators in making predictions.</p> <p>4. In exposed riverine sediments, >88% of predictions were correlated with observed taxa richness and an index of conservation status. Values predicted by exposed riverine sediment samples were correlated with those observed in temporary stream channels with comparable riparian (i.e. largely agricultural) land use, but not those observed in channels with contrasting (i.e. more urban) land use.</p> <p>5. Unimetric habitat indicators performed similarly to more complex multimetric indicators, with each explaining ≤6% of the variability in taxa richness and the index of conservation status. The different spatial scales at which invertebrates respond to habitat conditions and at which indicators record habitat conditions, and a more comprehensive training dataset that incorporates a full range of habitat conditions (i.e. land use), may improve future predictions.</p> <p>6. We demonstrate that invertebrate assemblage characteristics can be predicted regardless of in-channel conditions. Agreement between exposed riverine sediment predictions and temporary stream observations suggests that these predictions are transferable among a range of aquatic–terrestrial habitat types, and could thus be widely applied to aid conservation of riverine biodiversity in dynamic aquatic–terrestrial ecosystems.</p>
dmurraystoker/OGC-biomass: Long-term comparison of invertebrate communities in a blackwater river reveals taxon-specific biomass change
<p>Data, metadata, and R code for "Long-term comparison of invertebrate communities in a blackwater river reveals taxon-specific biomass change."</p> <p>Abstract</p> <p>1. Around the world, researchers are reporting declines in insect fauna. Though uncommonly evaluated in high-profile studies of insect declines, the community context of population trends can facilitate interpretation of the causes and consequences of such losses. Here, we aimed to explore the shifts in a well-studied invertebrate community of a blackwater river and identify potential catalysts of such change.</p> <p>2. We compared the density, biomass, and community structure of freshwater invertebrate assemblages separated by more than 30 years in the Ogeechee River, in the southeastern US, and found biomass declines. We also evaluated long-term trends in river discharge, water temperature, and precipitation.</p> <p>3. Overall, the biomass in the 2010s was approximately 60% of the total in the 1980s. Community analyses indicated that this decline was driven by reduced densities of large-bodied, filter-feeding insects, particularly Hydropsychidae caddisflies (Trichoptera). Conversely, predators and small-bodied primary consumers increased in density, though their contributions to overall biomass were minimal and their increased density was not sufficient to compensate for biomass declines. Seasonal shifts in both invertebrate populations and environmental parameters were evident, especially when focusing on discharge and dissolved organic carbon.</p> <p>4. Through a combination of direct analysis and the use of established research on the metabolic dynamics of the study site, we determined that the overall decline of freshwater invertebrate biomass may be driven by climate-related changes in flood dynamics: seasonal flooding that facilitates delivery of floodplain carbon to filter-feeding consumers has decreased over several decades. Water temperature had also increased and has likely had effects on the invertebrate assemblages.</p> <p>5. Whole-community evaluations such as this one, in contrast to single-taxon and abundance-based studies, provide critical information to elucidate the dynamics of freshwater impairment and insect loss in the Anthropocene.</p>
Invertebrate communities across wader habitats in Europe
<p>Grassland breeding waders have been steadily declining across Europe. Recent studies indicating a dramatic decline in grassland invertebrates' abundance and biomass, the key food of most grassland wader chicks, suggest a likely driver of the demise of waders. While agricultural intensification is generally inferred as the main cause for arthropod decline, there is surprisingly little information on the relationship between land use intensity and total arthropod abundance in grasslands. Here, we explored those relationships across several key wader breeding habitats by surveying ground-active, aerial and soil-dwelling invertebrate communities in five European countries that range from natural undisturbed bogs to intensively managed grasslands. Using maximum vegetation growth and soil moisture content, we investigated how they shape the size of the invertebrate community within and across different countries. We found predominantly positive relationships between grassland invertebrate abundance, biomass and body weight with increasing vegetation growth and soil moisture. Maximum vegetation growth was strongly positively related to ground-active invertebrate abundance and biomass and abundance of soil-dwelling invertebrates (mainly earthworms). Body weight of aerial invertebrates furthermore increased with increasing maximum vegetation growth. Our results provide little support for the hypothesis that agricultural practices associated with intensification of grassland management result in an abundance decline of invertebrate prey for wader chicks. Conservation practices aiming to enhance wader chick survival require a careful balancing act between maintaining habitat productivity to secure high prey abundance and keeping productivity low enough to maintain open swards that do not need to be cut before chicks have fledged.</p>
Data for: Variation in fatty acid content among benthic invertebrates in a seasonally driven system
<p><span>At temperate latitudes where seasonal changing environmental conditions strongly affect the magnitude, duration and species composition of pelagic primary production, macrobenthic organisms living below the photic zone rely on the sedimentation of this organic matter as their primary energy source. The succession from nutritious spring blooms to summer cyanobacteria is assumed to reduce food quality for benthic primary consumers and their fatty acid profiles. In contrast, we find low seasonal variability in fatty acid content of five benthic macroinvertebrates spanning two trophic levels in the Baltic Sea, a system with high seasonal variation in phytoplankton species composition. However, levels of the major FA groups vary greatly between benthic species. The results suggest that benthic macroinvertebrates have evolved FA metabolism adapted to degraded sedimenting material. Moreover, our study shows that species composition of benthic macrofauna rather than seasonal changing conditions affect availability of essential nutrients to higher trophic levels.</span></p>
North Pacific Subtropical Gyre 2018–2019 invertebrate biodiversity on macroplastic
<p>We show that the high seas are colonized by a diverse array of coastal species, which survive and reproduce in the open ocean, contributing strongly to its floating community composition. Analysis of rafting plastic debris in the Eastern North Pacific Subtropical Gyre revealed 37 coastal invertebrate taxa in total, largely of Western Pacific origin, exceeding pelagic taxa richness by three-fold. Coastal taxa, including diverse taxonomic groups and life history traits, occurred on 70.5% of debris items. Most coastal taxa possessed either direct development or asexual reproduction, possibly facilitating long-term persistence on rafts. Our results suggest that the historical lack of available substrate limited colonization of the open ocean by coastal species, rather than physiological or ecological constraints as previously assumed. It appears that coastal species persist now in the open ocean as a substantial component of a neopelagic community sustained by the vast and expanding sea of plastic debris.</p>
Data for: Plants, invertebrates, and birds of grasslands of northeastern Pennsylvania
<p>This dataset contains data for a study of primary productivity and diversity for grassland, meadow, and savanna (GMS) vegetation in northeastern Pennsylvania, USA, where the landscape is primarily forests, agriculture, and urban or suburban development. Data were collected in late summer and early fall of 2014-2015. It includes data for primary productivity, plant species diversity, invertebrate order diversity, and avian abundance and species diversity of 14 grasslands and open areas that were actively managed and three that apparently occurred naturally. Four grasslands were dominated by warm season grasses with the C<sub>4</sub> photosynthetic pathway, nine were dominated by C<sub>3</sub> grasses, forbs, and shrubs, and four had a mixture of both types.</p>

Fatty acid composition and content of seston, zooplankton, benthic invertebrates and fish in Lake Pyhäjärvi and Lake Köyliönjärvi
<p><span>We evaluated how cyanobacteria bloom, driven by agricultural eutrophication (defined as an increase in nutrients) or global warming, influence fatty acid profiles of phytoplankton, zooplankton (<em>Daphnia</em> + <em>Bosmina</em>), and fish (roach and perch) in eutrophic Lake Köyliöjärvi and mesotrophic Lake Pyhäjärvi. Regarding the nutritional value of food web components, we evaluated changes in the ω-3 and ω-6 polyunsaturated fatty acids (PUFA) of phytoplankton and consumers at different trophic levels. We report the fatty acid results as percentages (%) and content (µg FA mg<sup>-1</sup> C<sup>-1</sup>).</span></p>
Heliconia-dwelling invertebrate abundances following a simulated hurricane disturbance
<p>Disturbances like hurricanes can affect diversity and community composition, which may in turn affect ecosystem function. We examined how a simulated hurricane disturbance affected insect communities inhabiting the phytotelma (plant-held waters) of <em>Heliconia</em> <em>caribaea</em> in the Luquillo Experimental Forest of eastern Puerto Rico, a tropical island that frequently experiences hurricanes. We hypothesized that disturbance would alter diversity and that larger Heliconia would attract more species following disturbance due to the area-diversity relationship described by the Theory of Island Biogeography. Individual flower parts (bracts) of <em>Heliconia</em> inflorescences (racemes) were artificially disturbed via removal of existing insect communities, then after refilling with water, cohorts of <em>Heliconia</em> were destructively sampled biweekly for six weeks to assess recolonization patterns of α (bract level), β, and γ (summed across bracts; raceme level) diversity over time and across raceme sizes. Although we found no support for our hypothesis about the effect of raceme size on recolonization, our hypothesis regarding recolonization patterns over time was supported; species richness, evenness, and abundance of bracts increased directly after the disturbance and then decreased below pre-disturbance levels, and community composition at the raceme level changed significantly over time during recolonization. β diversity was also greater in smaller racemes compared to larger racemes, suggesting high heterogeneity across bracts of <em>Heliconia</em> racemes exacerbated by raceme size and age. Overall, our results highlight the importance of scale and appropriate measurements of diversity (particularly α) in experiments aiming to extrapolate conclusions about the ecological impacts of disturbances across different habitats and ecosystems.</p>
Fijian habitat and invertebrate species distribution modelling
<p><strong>Aim</strong></p> <p>Spatially explicit protections of coastal habitats determined on the current distribution of species and ecosystems risk becoming obsolete in 100 years if the movement of species ranges outpaces management action. Hence, a critical step of conservation is predicting the efficacy of management actions in future.

We then overlay predicted distribution models onto existing Fijian protected area network to assess whether today's conservation measures will afford protection to tomorrow's distributions.</p> <p><strong>Results</strong></p> <p>We develop species distribution models (SDMs) using MaxEnt, General Additive Models and Boosted Regression Trees and publicly available data from the Global Biodiversity Information Facility to predict changes in distribution of suitable habitat for mangrove forests, coral habitat, seagrass meadows and critical fisheries invertebrates under several IPCC climate change scenarios in 2070 or 2100.

Patagonia invertebrate densities
<p class="MsoNormal">The kelp forests of southern Patagonia have a large diversity of habitats, with remote islands, archipelagos, peninsulas, gulfs, channels, and fjords, which are comprised of a mixture of species with temperate and sub-Antarctic distributions, creating a unique ecosystem that is among the least impacted on Earth. We investigated the distribution, diversity, and abundance of marine macroinvertebrate assemblages from the kelp forests of southern Patagonia over a large spatial scale and examined the environmental drivers contributing to the observed patterns in assemblage composition. We analyzed data from 120 quantitative underwater transects (25 x 2 m) conducted within kelp forests in the southern Patagonian fjords in the Kawésqar National Reserve (KNR), the remote Cape Horn (CH) and Diego Ramírez (DR) archipelagos of southern Chile, and the Mitre Peninsula (MP) and Isla de los Estados (IE) in the southern tip of Argentina. We observed rich assemblages of macroinvertebrates among these kelp forests, with a total of 185 unique taxa from 10 phyla and 23 classes/infraorders across the five regions. The number of taxa per transect was highest at IE, followed by MP, CH, and KNR, with the lowest number recorded at DR. The trophic structure of the macroinvertebrate assemblages was explained mostly by wave exposure (28% of the variation), followed by salinity (12%) and the KNR region (11%). KNR was most distinct from the other regions with a greater abundance of deposit feeders, likely driven by low salinity along with high turbidity and nutrients from terrigenous sources and glacial melt. Our study provides the first broad-scale description of the benthic assemblages associated with kelp forests in this vast and little-studied region and helps to establish baselines for an area that is currently lightly influenced by local anthropogenic factors and less impacted by climate change compared with other kelp forests globally.</p>
Evidence that long-distance dispersal of aquatic invertebrates by ducks increases with propagule size
<ol> <li> <span>Migratory ducks are key dispersal agents for aquatic organisms, yet </span><span>differences in their potential for short- and long-distance dispersal are still poorly understood, particularly differences among </span><span>aquatic invertebrate taxa</span><span>. </span> </li> <li> <span>Using seven species of </span><span>aquatic invertebrates and </span><span>a duck species known to feed on them in the wild (the northern shoveler) </span><span>as a model system, we evaluated whether their potential for endozoochorous dispersal varies among 5 of the species and scales with propagule size for the 7 species. We also tested the expectation of a lower dispersal potential for invertebrate propagules, as compared to plant seeds; and evaluated whether intra-specific variation (in particular, sexual dimorphism) influences the potential of waterbirds as dispersal vectors. </span> </li> <li><span>An experiment with 5 invertebrate species demonstrated that most resting eggs (68–95%) were retrieved by 4 h after ingestion, with maximum gut passage times ranging from 16 h for <em>Daphnia</em> <em>magna</em> to 36 h for <em>Artemia</em> <em>salina</em> and <em>Thamnocephalus</em> <em>platyurus</em>. Using models that combine migratory duck movements with gut passage times, we show that aquatic invertebrates may disperse frequently over distances of 15–16 km (median dispersal distance) and regularly over distances up to 110–166 km (Q99 distance). </span></li> <li> <span>I</span><span>ncreasing propagule size resulted in increasing gut passage times, decreasing survival of gut passage and decreasing hatching success. While propagule size had no effects on 'regular' dispersal distances (mean, median, Q95 and Q99), the frequency of long-distance dispersal (LDD) increased with it. </span> </li> <li><span>Increasing propagule size therefore had two contrasting effects on invertebrate dispersal potential, decreasing the frequency of dispersal (less seeds dispersed) but increasing the potential for long-distance dispersal. </span></li> <li><span><em>Conclusions</em>: We provide evidence that endozoochory of invertebrate propagules by waterbirds results in frequent dispersal among wetlands (tens of km) and regular dispersal at regional scale (over a hundred km).</span></li> </ol>
Multiple dimensions of biodiversity mediate effects of temperature on invertebrate herbivory in a montane grassland
<p><span>Invertebrate herbivores are important and diverse, and their abundance and impacts will likely shift under climate change. Yet, past studies of invertebrate herbivory have documented highly variable responses to changing temperature, making it challenging to predict the direction and magnitude of these shifts. One explanation for these responses is that changing environmental conditions drive concurrent changes in plant communities and herbivore traits. The impacts of changing temperature on herbivory might therefore depend on how temperature combines and interacts with characteristics of plant and herbivore communities. To test this, we surveyed damage to leaves by invertebrate herbivores on </span><span>4400 plant individuals in 220 sampling plots along a 1101-meter elevational gradient. Increasing temperature drove community-level herbivory via at least three overlapping mechanisms: increasing temperature directly reduced herbivory, indirectly affected herbivory by reducing plant-community phylogenetic diversity, and indirectly affected herbivory by altering the effects of plant-community functional and phylogenetic diversity on herbivory. Consequently, increasing plant functional diversity reduced herbivory in colder environments while increasing plant phylogenetic diversity increased herbivory in warmer environments. Moreover, different herbivore feeding guilds varied in their response to temperature and plant community composition. These results indicate that, even along a single elevation gradient in a single year, a variety of mechanisms can concurrently drive herbivory, thereby supporting the hypothesis that a universal response of herbivory to changing environmental conditions is unlikely to exist. Instead, our results highlight the importance of considering both plant and herbivore community context to predict how climate change will alter invertebrate herbivory.</span></p>
Performance and preference of four above- and below-ground invertebrate and generalist herbivores on regionally and locally rare plant species
<ol> <li>Rare plant species are suggested to be less resistant to herbivores than common species. Their lower apparency and the fact that they often live in isolated populations, resulting in fewer herbivore encounters, might have led to the evolution of reduced defences. Moreover, their frequently lower levels of genetic diversity compared with common species could negatively affect their resistance against enemies. However, the hypothesis that plant resistance depends on plant regional and local rarity, independently of habitat and competitive and growth strategy, lacks evidence.</li> <li>To test this hypothesis, we assessed the performance and preference of one belowground and three aboveground generalist invertebrate herbivores from different taxonomic groups as indicators of plant resistance. Herbivores were fed a total of 62 regionally and locally rare and common plant species from Switzerland. We accounted for differences in a plant's growth and competitive strategy and habitat resource availability.</li> <li>We found that regionally and locally rare and common plant species did not generally differ in their resistance to most generalist herbivores. However, one herbivore species even performed better and preferred locally and regionally common plant species over rarer ones, indicating that common species are not more resistant, but tend to be less resistant. We also found that all herbivore species consistently performed better on competitive and large plant species, although different herbivore species generally preferred and performed better on different plant species. The latter indicates that the use of generalist herbivores as indicators of plant-resistance levels can be misleading.</li> <li> <em>Synthesis</em>: Our results show that rare plant species are not inherently less resistant than common ones to herbivores. Instead, our results suggest that the ability of plants to allocate resources away from defence towards enhancing their competitive ability might have allowed plants to tolerate herbivory, and to become locally and regionally common.</li> </ol>
