Waste not, want not: microsatellites remain an economical and informative technology for conservation genetics
<p>Comparisons of microsatellite and single-nucleotide polymorphisms (SNPs) have found that SNPs outperform microsatellites in population genetic analyses, calling into question the continued utility of microsatellites in population and landscape genetics. Yet highly polymorphic markers may be of value in species that have reduced genetic variation. This study repeated analyses previously done using microsatellites with SNPs developed from ddRAD sequencing in the black-capped vireo source-sink system. SNPs provided greater resolution of genetic diversity, population differentiation, and migrant detection but could not reconstruct parentage relationships due to insufficient heterozygosities. The biological inferences made by both sets of markers were similar: asymmetrical gene flow from source sites to the remaining sink sites. With the landscape genetic analyses, we found different results between the two molecular markers, but associations of the top environmental features (riparian, open habitat, agriculture, and human development) with dispersal estimates were shared between marker types. Despite the higher precision of SNPs, we find that microsatellites effectively uncover population processes and patterns and are superior for parentage analyses in this species with reduced genetic diversity. This study illustrates the continued applicability and relevance of microsatellites in population genetic research.</p>

Datasets for: Climate change and conservation of Caladenia orchids in Western Australia
<p>Occurence data for 26 <em>Caladenia </em>species for the paper: "<strong>Climate change and conservation of Caladenia orchids in Western Australia" </strong></p> <p><strong>Abstract</strong></p> <p>Understanding how species distributions are being shaped by current rises in atmospheric temperature is of immediate conservation importance. Orchids are a globally threatened plant family, with many species having narrow ranges and low abundances that heighten extinction risk due to rising atmospheric temperature. Using 26 rare and common <em>Caladenia </em>orchid species in Western Australia, we first performed a conservation assessment by calculating the proportion of populations that currently occur in conservation areas. We then compared current range extents with past and future climate scenarios. We performed a niche overlap test with a future climate scenario to test how the current population level climatic niche of these species will change. As some of these orchids frequently hybridize, we then quantified how ecogeographical isolation will change under future climates. Only 27% of all <em>Caladenia </em>populations are currently found in protected areas. Most species had reduced range extents in historically warmer climates. However, only three species will experience range extent contractions under future climate scenarios. The current population climatic niche has a 36% overlap with future climates, indicating that current population level conditions may change. Ecogeographical isolation will potentially increase in hybridizing species, thereby acting as a stronger barrier against hybridization. As <em>Caladenia </em>species evolved in seasonally dry conditions, this suggests that there is potential preadaptation to survive under elevated temperatures. Despite their physiological tolerances to elevated temperature, conservation of <em>Caladenia </em>species will depend on the availability of habitat to allow migration within future range limits, and the presence of their key mutualists. </p>
Data from: Species-habitat networks reveal conservation implications that other community analyses do not detect
<p><span>Grassland restoration is an important conservation intervention supporting declining insect pollinators, particularly in threatened calcareous grassland landscapes. While restoration is often assessed using simple diversity or the similarity to a target community metrics, this can fail to represent key aspects of community reconstruction. Here, we compare a new method, species-habitat networks, with techniques previously relied upon to understand the process of pollinator community restoration. The species-habitat network approach reveals details relevant to insect conservation that are not visible using standard measures of species richness, abundance, community similarity or network metrics. For instance, a shared set of butterflies and bumblebees found in ancient extensively managed grassland, the target community for restoration, were more likely to inhabit previously disturbed grassland than recently disturbed or reverting grasslands. We propose that species-habitat networks should be part of the standard analytical toolkit assessing the effectiveness of restoration, particularly for mobile species such as insects.</span></p>
