Data from: Examination of the efficacy of small genetic panels in genomic conservation of companion animal populations
<p>In many ways dogs are an ideal model for the study of genetic erosion and population recovery, problems of major concern in the field of conservation genetics. Genetic diversity in many dog breeds has been declining systematically since the beginning of the 1800's, when modern breeding practices came into fashion. As such, inbreeding in domestic dog breeds is substantial and widespread and has led to an increase in recessive deleterious mutations of high effect as well as general inbreeding depression. Pedigrees can in theory be used to guide breeding decisions, though are often incomplete and do not reflect the full history of inbreeding. Small microsatellite panels are also used in some cases to choose mating pairs to produce litters with low levels of inbreeding. However, the long-term impact of such practices have not been thoroughly evaluated. Here, we use forward simulation on a model of the dog genome to examine the impact of using limited markers panels to guide pairwise mating decisions on genome-wide population level genetic diversity. Our results suggest that in unmanaged populations, where breeding decisions are made at the pairwise- rather than population-level, such panels can lead to accelerated loss of genetic diversity at genome regions unlinked to panel markers, compared to random mating. These results demonstrate the importance of genome-wide genetic panels for managing and conserving genetic diversity in dogs and other companion animals.</p>
Data from: Can patterns of habitat use by western Nearctic-Neotropical migratory landbirds in winter inform conservation priorities?
<p>ABSTRACT—I use point-count survey data collected from 171 locations across 11 vegetation conditions in western Mexico to illustrate common patterns of winter habitat use by 97 Nearctic-Neotropical migratory landbird species. A number of bird species are relatively restricted in their habitat use, with some [e.g., Northern Waterthrush (<i>Parkesia noveboracensis</i>), American Redstart (<i>Setophaga ruticilla</i>)] occurring only in relatively undisturbed habitats, and others [e.g., Say's Phoebe (<i>Sayornis saya</i>), Horned Lark (<i>Eremophila alpestris</i>)] occurring only in relatively disturbed lands associated with agriculture. A large number of bird species [e.g., Cassin's Vireo (<i>Vireo cassinii</i>), MacGillivray's Warbler (<i>Geothlypis tolmiei</i>)] use every one of the vegetation types considered, from low-elevation tropical deciduous forests to high-elevation conifer forests. Bird species showing patterns of restricted habitat use deserve conservation attention, but so might more broadly distributed species that become significantly less abundant in human-altered habitats. Identifying the latter will require the inclusion of a wider spectrum of altered vegetation types/conditions than what I included here, or than what is typically considered in wildlife-habitat relationship programs.</p>

Data from: A functionally conserved mechanism of modulation via a vestibule site in pentameric ligand-gated ion channels
<p>Pentameric ligand-gated ion channels (pLGICs) belong to a class of ion channels involved in fast synaptic signaling in the central and peripheral nervous systems. Molecules acting as allosteric modulators target binding sites that are remote from the neurotransmitter binding site, but functionally affect coupling of ligand binding to channel opening. Here, we investigated an allosteric binding site in the ion channel vestibule, which has converged from a series of studies on prokaryote and eukaryote channel homologs. We discovered single domain antibodies, called nanobodies, which are functionally active as allosteric modulators, and solved co-crystal structures of the prokaryote channel ELIC bound either to a positive (PAM) or a negative (NAM) allosteric modulator. We extrapolate the functional importance of the vestibule binding site to eukaryote ion channels, suggesting a conserved mechanism of allosteric modulation. This work identifies key elements of allosteric binding sites and extends drug design possibilities in pLGICs using nanobodies.</p>
Conservation genomic analysis of the Croatian indigenous Black Slavonian and Turopolje pig breeds
<p>The majority of the nearly 400 existing local pig breeds are adapted to specific environments and human needs. The demand for large production quantities and the industrialized pig production have caused a rapid decline of many local pig breeds in recent decades. Black Slavonian pig and Turopolje pig, the latter highly threatened, are the two Croatian local indigenous breeds typically grown in extensive or semi-intensive systems. In order to guide a long-term breeding program to prevent the disappearance of these breeds, we analyzed their genetic diversity, inbreeding level and relationship with other local breeds across the world, as well as modern breeds and several wild populations, using high throughput genomic data obtained using the Illumina Infinium PorcineSNP60 v2 BeadChip. Multidimensional scaling analysis positioned Black Slavonian pigs close to the UK/North American breeds, while the Turopolje pig clustered within the Mediterranean breeds. Turopolje pig showed a very high inbreeding level (F<sub>ROH>4Mb</sub>=0.400 and F<sub>ROH>8Mb</sub>=0.332) that considerably exceeded the level of full-sib mating, while Black Slavonian pig showed much lower inbreeding (F<sub>ROH>4Mb</sub>=0.098 and F<sub>ROH>8Mb</sub>=0.074), indicating a planned mating strategy. In Croatian local breeds we identified several genome regions showing adaptive selection signals that were not present in commercial breeds. The results obtained in this study reflect the current genetic status and breeding management of the two Croatian indigenous local breeds. Given the small populations of both breeds, a controlled management activity has been implemented in Black Slavonian pigs since their commercial value has been recognized. In contrast, the extremely high inbreeding level observed in Turopolje pig argues for an urgent conservation plan with a long-term, diversity-oriented breeding program.</p>
Data from: Agri-environment conservation set-asides have co-benefits for connectivity
<p>Widespread declines in farmland biodiversity have led to state-funded schemes which take land out of production to create (semi-)natural habitats for biodiversity (e.g. EU agri-environment schemes; US Conservation Reserve Program). Common features of such schemes are grassland strips at the edges of agricultural fields, and we examine potential co-benefits of these biodiversity set-asides for contributing to grassland connectivity. Although set-aside strips had negligible impact on landscape-scale species persistence (using metapopulation models parameterized for flying insects run on 267 landscapes of ~30 000 ha across England), they nonetheless improved connectivity in 74% (198/267) of landscapes (comparing landscapes with and without set-asides), as shown by range expansion rates increasing by up to 100%. Benefits of set-aside strips varied according to species type (high/low dispersal, high/low population density), but had little benefit for species with low dispersal and small population sizes, which enerally failed to expand. High dispersal/high density species were already successful expanders regardless of set-asides (> 75% of simulations were successful without set-sides) although expansion rates were still improved when set-asides were added. Whilst alternative strategies for placement of set-aside strips (more/less aggregated), revealed no consensus 'better' strategy across species types, set-aside benefits were generally greatest in landscapes with intermediate availability of semi-natural grassland (0.5-4% over). We conclude that small-scale set-asides have the potential to improve connectivity, which we expect to help some species track climate change, and connect habitat patches within existing climate space for others. However, set-asides are unlikely to benefit low dispersal species which are probably at greatest risk from agricultural intensification.</p> <p> </p> <p> </p>
Data from: To burn or not to burn: comparing re-introducing fire with cutting an encroaching conifer for conservation of an imperiled shrub-steppe
Woody vegetation has increased on rangelands worldwide for the past 100-200 years, often because of reduced fire frequency. However, there is a general aversion to re-introducing fire and therefore, fire-surrogates are often used in its place to reverse woody plant encroachment. Determining the conservation effectiveness of re-introducing fire compared to fire-surrogates over different time scales is needed to improve conservation efforts. We evaluated the conservation effectiveness of re-introducing fire with a fire-surrogate (cutting) applied over the last ~30 years to control juniper (Juniperus occidentalis Hook.) encroachment on 77 sagebrush-steppe sites. Critical to conservation of this imperiled ecosystem is to limit juniper, not encourage exotic annual grasses, and promote sagebrush dominance of the overstory. Re-introducing fire was more effective than cutting at reducing juniper abundance and extending the period of time that juniper was not dominating the plant community. Sagebrush was reduced more with burning than cutting. Sagebrush, however, was predicted to be a substantial component of the overstory longer in burned than cut areas because of more effective juniper control. Variation in exotic annual grass cover was explained by environmental variables and perennial grass abundance, but not treatment, with annual grasses being problematic on hotter and drier sites with less perennial grass. This suggests that ecological memory varies along an environmental gradient. Re-introducing fire was more effective than cutting at conserving sagebrush-steppe encroached by juniper over extended time-frames; however, cutting was more effective for short-term conservation. This suggests fire and fire-surrogates both have critical roles in conservation of imperiled ecosystems.

Data from: Islands in the desert for cavity-nesting bees and wasps: ecology, patterns of diversity, and conservation at oases of Baja California peninsula
<p>Aims: The oases of Baja California peninsula (BCP) have been proposed as important hotspots of biodiversity that hold an exceptional richness in the middle of desert conditions. We provide the effect of habitat, climatic, biogeographic and anthropogenic disturbance on communities of cavity nesting taxa, emphasizing on bees, wasps and their natural enemies. Location: Baja California Peninsula, Northwest Mexico.</p> <p>Methods: In oases of BCP and desert neighbor environments, trap-nesting taxa were evaluated in response to factors affecting the nest abundance, richness, and community structure. We used statistical models to find the variables controlling the nest abundance and ecological analyses to determine the habitat effect on diversity under different scenarios of disturbance and latitude.</p> <p>Results: The nest abundance varied between bees and wasps, but solar irradiation and relative humidity influenced the abundance of both groups. In general, abundance and richness were higher in oases. Bees did not discriminate between oasis and desert habitats to nest and mud-daubing wasps were highly dependent of oases. However, there were exceptions in both groups. The degree of anthropogenic disturbance affected the species composition, richness, and natural enemies.</p> <p>Main conclusions: The oases of Baja California seem to be functioning as mesic islands into the desert, each oasis hosting a great and unique richness of cavity-nesting taxa. About 65% of nest abundance and 50% of species occurred exclusively in the oasis. Thus, at least 21 species could be threatened if the oases of BCP disappear in the future. Local conditions are shaping the community structure of species, but also large-scale factors, e.g. climate and biogeographic patterns seem to be influencing the community structure. Since habitat loss and fragmentation can be a major problem in most oases, strategies to maintain the ecosystem services of pollinators and predators should be included in the conservation programs of these fragile habitats.</p>

Sustainable harvesting and conservation of Laelia furfuracea, a rare epiphytic orchid from Oaxaca, Mexico
Many epiphytic orchids are harvested in Mexico for different purposes. Laelia furfuracea is one of the most intensively traded species. Its inflorescences are used as ornaments during the December festivities. We investigated the effect of severing the flowering pseudobulb. This is the traditional technique frequently used by collectors at the study area. We wished to investigate its effects on the production of new pseudobulbs, as well as on their size and flowering probability. Also, we examined the survival probability and growth of individuals that had fallen on the ground to evaluate their potential as trading resources. Inflorescence collection did not affect the production of new pseudobulbs the following season. However, it affected the size of these pseudobulbs, as well as their flowering probability. Yet, the direction of this effect was not consistent between years. Nearly six percent of all L. furfuracea plants at the study site were found on the ground. Over 80 percent of them survived for at least two years, although most of them showed pseudobulb loss over that period of time. We conclude that harvesting of flowering pseudobulbs may be sustainable in terms of its effects on plant performance, at least in the short term. The active management of plants that have fallen on the ground may reduce the harvesting pressure on natural populations. Harvesting of flowering pseudobulbs may diminish some aspects of plant performance, but its effects need to be evaluated with complete life cycle data and take into account interannual variation in vital rates.
