The hidden legacy of megafaunal extinction: loss of functional diversity and resilience over the late Quaternary at Hall's Cave
<p>This dataset contains trait data and R code used in the analysis for the paper "Hedberg, C.P., Lyons S.K., & Smith F.A. (2021). THe Hidden Legacy of megafaunal extinction: loss of functional diversity and resilience over the Late Quaternary at Hall's Cave. Global Ecology and Biogeography. https://doi.org/10.1111/geb.13428"</p> <p>We collected data for eight functional traits (mass, diet, arboreality, cursoriality, soil disturbance, group size, activity period, migration habit) that collectively describe a species' ecological role and influence on ecosystem processes. With these data, we investigated changes in functional diversity and redundancy of a local mammal community over time at Hall's Cave, a site in Central Texas with a continuous record from 21,000 years ago to the present. Additionally, we included several common introduced and domestic species to the modern community to test whether they restore some lost ecological function. </p> <p>We found that declines in functional diversity were greater than expected given the decrease in species richness, implying lost taxa contributed higher than average distinct ecological function. Functional distances between remaining species increased through time leading to lowered functional redundancy in younger communities. However, recently introduced taxa increased functional diversity to levels similar to the Holocene and partially restored functional space occupied by Late Pleistocene fauna. Our local-scale analysis demonstrates how prolonged biodiversity erosion not only leads to functionally depauperate communities, but critically lowers ecological resilience to future disturbance.</p>
Use of cenotes and the cave environment by mammals on the Yucatán Peninsula, Mexico
<p><span>Mammals are important sources of nutrients to cave ecosystems, and in some circumstances, caves may be an essential resource for mammals. Few studies, however, have focused on the use of caves by terrestrial mammals. </span><span>We used camera traps at 17 cenotes on the Yucatán Peninsula to determine patterns of use by mammals. Eighteen non-volant mammal taxa were identified using cenotes, the most commonly occurring being lowland paca (<em>Agouti paca</em></span><span>), opossums (<em>Didelphis</em> spp.), white-nosed coati (<em>Nasua narica</em>), gray fox (<em>Urocyon cinereoargenteus</em>), tayra, (<em>Eira barbara)</em> and gray four-eyed opossum (<em>Philander opossum</em>); collectively these taxa accounted for 76% of all mammal records. We also recorded several felids using cenotes, including jaguar (<em>Panthera onca</em>) and puma (<em>Puma concolor</em>). Activity patterns at cenotes usually matched normal activity schedules but some species were nocturnal in the forest but diurnal at cenotes. Mammals mostly accessed cenotes to drink, but a range of activities were recorded including foraging, nesting, mating, resting and bathing.</span></p>

Single-cell transcriptome analysis of the in vivo response to viral infection in the cave nectar bat Eonycteris spelaea
<p>Bats are reservoir hosts of many zoonotic viruses with pandemic potential in humans. Here, we<br> utilized single-cell transcriptome sequencing (scRNA-seq) to provide detailed comparative<br> analyses of the immune repertoire and the transcriptional responses in the bat lungs upon in<br> vivo infection with a double-stranded RNA virus, Pteropine orthoreovirus PRV3M. Neutrophils<br> were observed to have basally high IDO1 expression, uniquely amongst mammals currently<br> profiled by scRNA-seq. NK/T cells were the most abundant immune cell type in lung tissue, and<br> included three distinct CD8 + effector T cell populations delineated by the differential expression<br> of KLRB1, GFRA2 and DPP4. We identified NK/T clusters which up-regulated genes involved in<br> T-cell activation and effector function early after viral infection. Alveolar macrophages and<br> classical monocytes were key drivers of antiviral interferon signaling. Infection also resulted in<br> the expansion of a CSF1R + population expressing collagen-like genes, which became the<br> predominant myeloid cell type after infection. This work uncovers novel features relevant to viral<br> disease tolerance in bats, lays a foundation for future in vivo and in vitro experimental<br> investigations, and serves as a key resource for comparative immunology studies across bats<br> and other mammals.</p> <p> </p> <p>This upload is the transcriptome fasta file used for alignment for the dataset.</p>

Interpreting the mammal deposits of Cloggs Cave (SE Australia), GunaiKurnai Aboriginal Country, through community-led partnership research
<p>Palaeontological animal bone deposits are rarely investigated through research partnerships where the local First Nations communities have a defining hand in both the research questions asked and the research processes. Here we report research undertaken through such a partnership approach at the iconic archaeological site of Cloggs Cave (GunaiKurnai Country, East Gippsland), in the southern foothills of SE Australia's Great Dividing Range.</p> <p>A new excavation was combined with detailed chronometric dating, high-resolution 3D mapping, and geomorphological studies. This allowed for the interpretation of a sequence of stratigraphic layers spanning from a lowermost excavated mixed layer dated to between 25,640–48,470 cal BP, to a dense set of uppermost, ash layers dated to between 1460–3360 cal BP. This long and well-dated chronostratigraphic sequence enabled temporal trends in the abundant small mammal remains to be examined.</p> <p>The fossil assemblage consists of at least 31 taxa of mammals which change in proportions through time. Despite clear evidence that the Old Ancestors repeatedly carried vegetation into the cave to fuel cool fires (no visible vegetation grows in Cloggs Cave), we observed little to no evidence of cooking fires or calcined bone, suggesting that people had little involvement with the accumulation of the faunal remains. Small mammal bones were most likely deposited in the cave by large disc-faced owls, <em>Tyto novaehollandae</em> (Masked Owl) or <em>Tyto tenebricosa</em> (Sooty Owl).</p> <p>Despite being well-dated and largely undisturbed, the Cloggs Cave assemblage does not appear to track known Late Quaternary environmental change. Instead, the complex geomorphology of the area fostered a vegetation mosaic that supported mammals with divergent habitat preferences. The faunal deposit suggests a local ancestral landscape characterised by a resilient mosaic of habitats that persisted over thousands of years, signaling that the Old Ancestors burned landscape fires to encourage and manage patches of different vegetation types and ages within and through periods of climate change.</p>
Bell Caves at Beit Guvrin National Park
The man-made Bell Caves in Beit Guvrin, Israel served as quarries that supplied building materials to the cities of the coastal plain and Beit Guvrin during the 7th-10th centuries CE. The media source for this 'proof-of-principle' model was a 360 video camera used in a walking tour. 500, 360-degree equirectangular images were extracted from the video, each image then being run through the Flexify v2 Photoshop plugin, with '12 views' as the output projection. The output of the Flexify plugin is a single large image comprising of 12 rectilinear overlapping views side by side, and spanning the full 360 degrees. The Flexify plugin output was then split into 12 separate images using, for example Photoscape or XnViewMP. These (now 6000) images were used as the actual input source for the model generation. Motion blur within the images, caused by the non stationary video camera being employed in low lighting conditions (causing relatively long camera shutter speeds), has reduced the overall resolution of the model.
