Data from: Deciduous forests hold conservation value for birds within South Andaman Island, India
<p>We assessed the importance of deciduous and evergreen habitats for forest birds (including several endemic and threatened species) within South Andaman Island, India. To this end, we compared the composition and diversity (taxonomic, functional and phylogenetic) of forest birds across the two habitat types, and evaluted species-specific responses to habitat variables within the island.</p> <p>The dataset collected and R codes used in this study are published here. Bird species traits were sourced from Tobias et al. (2022) and Wilman et al. (2014). Phylogenetic trees were sourced from <a href="https://birdtree.org/">birdtree.org</a> (Jetz et al. 2012).</p> <p><br><strong>Taxonomic Coverage: </strong>Birds, 54 species</p> <p><strong>Geographic Coverage:</strong> South Andaman Island, Andaman and Nicobar Islands, India</p> <p><strong>Temporal Coverage:</strong> March-May 2022 and December 2022-April 2023</p> <p> </p> <p><strong>Brief summary of field methods: </strong><br>We conducted line-transect surveys for forest birds across evergreen and deciduous forests in South Andaman Island, India. <br>Twenty-seven transects were sampled either in the morning (between 0515 – 0930 hrs) or in the afternoon (between 1515 – 1730 hrs) from March-May 2022 and December 2022-April 2023.

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>
Data from: Maintenance of genetic diversity in an introduced island population of Guanacos after seven decades and two severe demographic bottlenecks: implications for camelid conservation
Fifteen Guanacos were introduced to Staats Island in Falklands/Malvinas archipelago from Patagonia in the 1930s. After introduction, the Guanaco population increased to almost 400 animals that retained a footprint of the founding effect and bottleneck reflected in the genetic status of this isolated population. The goals of this study were to (i) make a genetic assessment of this island population through comparisons with mainland populations and simulation, and (ii) assess the likely source population of the introduced Guanacos. Genetic variation estimated from 513 bp of mitochondrial DNA sequence and 15 microsatellite loci were compared among 154 Guanacos collected from eight localities, including the adjacent mainland and the islands of Tierra del Fuego and Staats Island. Of the 23 haplotypes observed among our samples, the Staats Island population only contained three haplotypes, all of which were shared with the Monte Leon population in southern Patagonia. Mitochondrial DNA and microsatellite variation on Staats Island were comparable to most mainland populations and greater than those observed on Tierra del Fuego. Patterns of genetic structure suggest that the Staats Island Guanaco population was founded with animals from southern Patagonia (as opposed to northern Patagonia or Tierra del Fuego), but that effective reductions in population size lasted only a few generations and that surviving animals were a random sample of the pre-bottleneck genetic variation.
Data from: Conservation genetics of the Philippine tarsier: cryptic genetic variation restructures conservation priorities for an island archipelago primate
Establishment of conservation priorities for primates is a particular concern in the island archipelagos of Southeast Asia, where rates of habitat destruction are among the highest in the world. Conservation programs require knowledge of taxonomic diversity to ensure success. The Philippine tarsier is a flagship species that promotes environmental awareness and a thriving ecotourism economy in the Philippines. However, assessment of its conservation status has been impeded by taxonomic uncertainty, a paucity of field studies, and a lack of vouchered specimens and genetic samples available for study in biodiversity repositories. Consequently, conservation priorities are unclear. In this study we use mitochondrial and nuclear DNA to empirically infer geographic partitioning of genetic variation and to identify evolutionarily distinct lineages for conservation action. The distribution of Philippine tarsier genetic diversity is neither congruent with expectations based on biogeographical patterns documented in other Philippine vertebrates, nor does it agree with the most recent Philippine tarsier taxonomic arrangement. We identify three principal evolutionary lineages that do not correspond to the currently recognized subspecies, highlight the discovery of a novel cryptic and range-restricted subcenter of genetic variation in an unanticipated part of the archipelago, and identify additional geographically structured genetic variation that should be the focus of future studies and conservation action. Conservation of this flagship species necessitates establishment of protected areas and targeted conservation programs within the range of each genetically distinct variant of the Philippine tarsier.
Data from: Critically endangered island endemic or peripheral population of a widespread species? Conservation genetics of Kikuchi's gecko and the global challenge of protecting peripheral oceanic island endemic vertebrates
Aim: To highlight the significant conservation challenge of evaluating peripheral endemic vertebrates in island archipelago systems and to assess empirically the complexities of approaches to conservation genetic studies across political and biogeographic boundaries. To demonstrate the poignant need for international collaboration and coordination when species delimitation problems with high conservation concern involve island endemics with biogeographically peripheral ranges. Location: Southeast Asia, Lanyu Island, Taiwan, and the Philippines. Methods: Genetic samples were collected and sequenced for one mitochondrial gene and five nuclear loci for species of the Gekko mindorensis-G. kikuchii species complex in Southeast Asia. We used maximum likelihood and Bayesian phylogenetic methods and coalescent-based species delimitation analyses to estimate phylogeographic relationships, construct multilocus haplotype networks and test putative species boundaries. Results: Phylogenetic and population genetic analyses suggest that Kikuchi's Gecko may represent a peripheral population of a widespread species distributed from the northern Philippines to Taiwan. However, we identify a discrepancy between inferences of species boundaries resulting from methods based on allele frequencies versus coalescent-based methods that incorporate evolutionary history. Coalescent-based analyses suggest that G. kikuchii may be a distinct evolutionary lineage. Our study underscores the need for coalescent-based methods in conjunction with population genetic approaches for conservation genetic assessments of widespread species. Main conclusions: This study joins a few recent works suggesting that Philippine-derived anomalies in the fauna of Lanyu (and possibly greater Taiwan) are worthy of careful reconsideration. Determining whether each is the result of recent human-mediated introduction or (possibly more ancient) natural dispersal should be the goal of future studies on this seldom-conceived biogeographic relationship. Isolated species endemic to islands on the outer periphery of biogeographic and political regions represent particular conservation challenges. This is especially true if a species occurs on an isolated island that is allied biogeographically with one nation, but politically administered by another.
