Data from: Prey abundance and leopard diet in a plantation and rainforest landscape, Anamalai Hills, Western Ghats

<p>Leopards use a wide range of habitats from natural forests to plantations in human-dominated landscapes. Within interface areas, understanding leopard ecology and diet can help in conservation management and conflict avoidance. In a fragmented rainforest and plantation landscape in southern India, we examined diet of large carnivores (with a focus on leopards) using scat analysis with DNA-based identification of predator species, and estimated relative abundance of prey species in different land uses through transect surveys. Large carnivores predominantly consumed wild prey species (98.1%) and domestic prey species contributed &lt;2% to overall prey biomass. For leopards, four wild prey species (Indian muntjac, Indian spotted chevrotain, sambar and Indian porcupine) contributed 95.1% of prey biomass, with the rest being minor wild prey species (no livestock in identified scats). Wild prey species occurred across the landscape but varied in relative abundance by land-use type, with forest fragments supporting higher abundance of many species relative to tea and coffee plantations. As large carnivores mainly depend on wild prey and rainforest fragments act as refuges for these mammals within the tea and coffee plantations, it is important to continue to retain or restore these forest fragments.</p> <p>This dataset contains abundance data on mammals (large carnivores and their prey species), using direct and indirect sign surveys along line and belt transects, respectively, as well as data on remains of prey species in large carnivore scats. This dataset is part of a study (published paper under Related works) on leopard ecology in a landscape containing commercial plantations of tea and coffee, and rainforest fragments and protected area. These data were collected between 2008 and 2010 in Valparai plateau and Anamalai Tiger Reserve in the Western Ghats, India. The dataset contains following files:</p> <p>1) Transect_details.csv<br> 2) Transect_repeats.csv<br> 3) Mammals_Direct_signs.csv<br> 4) Mammals_Indirect_signs.csv<br> 5) Large_carnivores_Indirect_signs.csv<br> 6) Large_carnivore_Diet.csv</p> <p>More details regarding the above files can be found in ReadMe_Data_ColumnNames.txt.</p> <p><strong>Update, version 2</strong>: Data were updated on 4 May 2020.

Multituberculate mammals from the Middle Jurassic of Western Siberia, Russia, and the origin of Multituberculata

Tashtykia primaeva gen. et sp. nov. and Tagaria antiqua gen. et sp. nov. (Multituberculata incertae sedis) are described based on isolated teeth from the Middle Jurassic (Bathonian) Itat Formation from the Berezovsk coal mine in Krasnoyarsk Territory, Western Siberia, Russia. Tashtykia primaeva gen. et sp. nov. is characterized by a P5 with three rows of cusps (cusp formula 2B:4M:6L) and a high sectorial p4 with two triangular lobes, five serrations associated with labial and lingual ridges, and a unique distal cusp. Tagaria antiqua gen. et sp. nov. differs from all other multituberculates by a very long P5 with flat crown and many cusps arranged in three rows (4B:6M:7L). Morphologically the teeth of Kermackodon and Megaconus are transitional between Euharamiyida and Middle Jurassic Multituberculata. Kermackodon shares several characteristics with Euharamiyida, such as pointed cusps on the molars connected by longitudinal ridges, a distolabial cusp on the M2 that is higher than the other cusps, and a single large sectorial premolar (p4) with a distal basin. The euharamiyidan characters of Megaconus are an ultimate upper premolar with a shorter lingual side, a p4 with a distal basin, and one cusp on the molars being larger than the other cusps. In addition, Megaconus shares an ultimate upper premolar with three rows of cusps, horizontal wear on the molars, and pyramidal cusps on the molars separated by transverse grooves with multituberculates. The multituberculate characters of Kermackodon include horizontal rather than basined wear on the surface of the molars and serrations on the p4.

Evolutionary stasis, ecophenotypy, and environmental controls on ammonite morphology in the Late Cretaceous (Maastrichtian) Western Interior Seaway, USA

<p class="Abstract">We test for the presence of evolutionary stasis in a species of Late Cretaceous ammonoid cephalopod, <i>Hoploscaphites nicolletii</i>, from the North American Western Interior Seaway. A comprehensive dataset of morphological traits was compiled across the entire spatial and temporal range of this species. These were analyzed in conjunction with sedimentologically and geochemically derived palaeoenvironmental conditions hypothesized to apply selective pressures. All changes in shell shape were observed to be ephemeral and reversable, that is, no unidirectional trend could be observed in any of the morphological traits analyzed. Correlations between palaeoenvironmental conditions and morphological traits suggests ecophenotypic processes were at play, however, either environmental changes were too minor and/or provided no isolating mechanism to drive speciation. These data support mechanisms of stasis such as homogenizing gene flow or stabilising selection under a fluctuating optimum (likely reflecting spatiotemporally heterogeneous palaeoenvironmental conditions). Finally, changes in shell size were not significantly associated with changes in shell-specific δ<sup>18</sup>O, despite a correlation between shell size and δ<sup>18</sup>O averaged across horizons. This suggests a mismatch in scales of geochemical sampling that supports caution when making broad interpretations based on averaged geochemical data.</p>

Small shelly fossils and carbon isotopes from the early Cambrian (Stage 3-4) Mural Formation of western Laurentia

<p>The extraordinary window of phosphatised and phosphatic Small Shelly Fossils (SSFs) during the early and middle Cambrian is an important testament to the radiation of biomineralising metazoans. While SSF are well known from most Cambrian palaeocontinents during this time interval, western Laurentia has relatively few SSF faunas. Here we describe a diverse SSF fauna from the early Cambrian (Stage 3-4) Mural Formation at three localities in Alberta and British Columbia, Canada, complemented by carbon isotope measurements at two of the recorded sites to aid in a potential future bio-chemostratigraphic framework.. The fauna expands the recorded SSF assemblage diversity in western Laurentia and includes several brachiopods, four bradoriids, three chancelloriids, two hyoliths, a tommotiid and a helcionellid mollusc as well as echinoderm ossicles and specimens of <i>Microdictyon</i>, <i>Volborthella </i>and <i>Hyolithellus</i>. New taxa include the tommotiid genus <i>Canadiella</i> gen. nov., the new bradoriid species <i>Hipponicharion perforata</i> sp. nov. and <i>Pseudobeyrichona taurata</i> sp. nov. Compared to contemporaneous faunas from western Laurentia, the fauna is rich, particularly in taxa with originally phosphatic shells, which appear to be associated with archaeocyathid buildups. This suggests that the generally low faunal diversity in western Laurentia may be at least partly a consequence of poor sampling of suitable archaeocyathan reef environments. In addition, the tommotiid <i>Canadiella filigrana</i> appears to be of biostratigraphic significance in Cambrian Stage 3 strata of western Laurentia and the unexpected high diversity of bradoriid arthropods in the fauna also suggests that this group may prove useful for biostratigraphic resolution in the region.</p>

Data from: Allopatric divergence and hybridization within Cupressus chengiana (Cupressaceae), a threatened conifer in the northern Hengduan Mountains of western China

<p class="CxSpFirst">Having a comprehensive understanding of population structure, genetic differentiation and demographic history is important for the conservation and management of threatened species. High‐throughput sequencing (HTS) provides exciting opportunities to address a wide range of factors for conservation genetics. Here, we generated HTS data and identified 266,884 high‐quality single nucleotide polymorphisms from 82 individuals of <i>Cupressus chengiana </i>, to assess population genomics across the species' full range, comprising the Daduhe River (DDH), Minjiang River (MJR) and Bailongjiang River (BLJ) catchments in western China. admixture , principal components analysis and phylogenetic analyses indicated that each region contains a distinct lineage, with high levels of differentiation between them (DDH, MJR and BLJ lineages). MJR was newly distinguished compared to previous surveys, and evidence including coalescent simulations supported a hybrid origin of MJR during the Quaternary. Each of these three lineages should be recognized as an evolutionarily significant unit (ESU), due to isolation, differing genetic adaptations and different demographic history. Currently, each ESU faces distinct threats, and will require different conservation strategies. Our work shows that population genomic approaches using HTS can reconstruct the complex evolutionary history of threatened species in mountainous regions, and hence inform conservation efforts, and contribute to the understanding of high biodiversity in mountains.</p>

Data from: Effects of Habitat Structure and Adjacent Habitats on Birds in Tropical Rainforest Fragments and Shaded Plantations in the Western Ghats, India

<p>This dataset includes bird community, habitat structure, and vegetation data from the following publication:</p> <p>Raman, T.R.S. 2006. Effects of Habitat Structure and Adjacent Habitats on Birds in Tropical Rainforest Fragments and Shaded Plantations in the Western Ghats, India. <em>Biodiversity and Conservation</em> 15: 1577–1607. https://doi.org/10.1007/s10531-005-2352-5</p> <p><strong>Abstract: </strong>As large nature reserves occupy only a fraction of the earth's land surface, conservation biologists are critically examining the role of private lands, habitat fragments, and plantations for conservation. This study in a biodiversity hotspot and endemic bird area, the Western Ghats mountains of India, examined the effects of habitat structure, floristics, and adjacent habitats on bird communities in shade-coffee and cardamom plantations and tropical rainforest fragments. Habitat and birds were sampled in 13 sites: six fragments (three relatively isolated and three with canopy connectivity with adjoining shade-coffee plantations and forests), six plantations differing in canopy tree species composition (five coffee and one cardamom), and one undisturbed primary rainforest control site in the Anamalai hills. Around 3300 detections of 6000 individual birds belonging to 106 species were obtained. The coffee plantations were poorer than rainforest in rainforest bird species, particularly endemic species, but the rustic cardamom plantation with diverse, native rainforest shade trees, had bird species richness and abundance comparable to primary rainforest. Plantations and fragments that adjoined habitats providing greater tree canopy connectivity supported more rainforest and fewer open-forest bird species and individuals than sites that lacked such connectivity. These effects were mediated by strong positive effects of vegetation structure, particularly woody plant variables, cane, and bamboo, on bird community structure. Bird community composition was however positively correlated only to floristic (tree species) composition of sites. The maintenance or restoration of habitat structure and (shade) tree species composition in shade-coffee and cardamom plantations and rainforest fragments can aid in rainforest bird conservation in the regional landscape.</p>

Data from: First record of organic-walled microfossils from the Tonian Shiwangzhuang Formation of the Tumen Group in western Shandong, North China

<p>Organic-walled microfossils offer an important window onto the biospheric evolution in pre-Cryogenian and provide biostratigraphic implications for many Proterozoic fossiliferous sequences which are poorly age constrained for the lack of reliable radiometric date. Recently, macroscopic carbonaceous compression fossils have been reported for the first time from the Tonian Shiwangzhuang Formation of the Tumen Group in western Shandong, North China. However, organic-walled microfossils have never been discovered in the Shiwangzhuang Formation before. To improve our knowledge about Proterozoic biodiversity in North China, we conducted a micropaleontological survey on the argillaceous limestone samples of the Shiwangzhuang Formation, which also contain macroscopic carbonaceous compression fossils, from the Baishicun section in Anqiu, Western Shandong, North China. Our investigation shows that the Shiwangzhuang microfossil assemblage is dominated by smooth-walled sphaeromorphic acritarchs and cyanobacterium-like filaments and relatively low abundance of other acritarchs, including 15 taxa, such as <i>Polysphaeroides filliformis</i>, <i>Ostiana</i> <i>microcystis</i>, <i>Simia annulare</i>, ?<i>Jacutianema </i>sp., <i>Pellicularia tenera</i>, <i>Polythrichoides lineatus</i>, and <i>Navifusa actinomorpha</i>. The Shiwangzhuang organic-walled microfossil assemblage, although consisting of long-ranging taxa and without age diagnostic taxa, is not contradictary with a Tonian age suggested by macroscopic carbonaceous compression fossils,<i> </i>including the <i>Chuaria</i>-<i>Tawuia </i>and <i>Sinosabellidites</i>-<i>Protoarenicola</i>-<i>Pararenicola </i>assemblages, revealed from the same horizon of the Shiwangzhuang Formation and organic-walled microfossil assemblage, including the late Mesoproterozoic to Tonian index fossils <i>Trachyhystrichosphaera aimika</i>, from the underlying Tongjiazhuang Formation. However, it is also worth noting that a Cryogenian or Ediacaran age cannot be completely excluded based just on the microfossils because of their limited biostratigraphic utility.</p>

Data from: Effects of restoration on tree communities and carbon storage in rainforest fragments of the Western Ghats, India

Ecological restoration is a leading strategy for reversing biodiversity losses and enhancing terrestrial carbon sequestration in degraded tropical forests. There have been few comprehensive assessments of recovery following restoration in fragmented forest landscapes, and the efficacy of active versus passive (i.e., natural regeneration) restoration remains unclear. We examined 11 indicators of forest structure, tree diversity and composition (adult and sapling), and aboveground carbon storage in 25 pairs of actively restored (AR; 7–15 yr after weed removal and mixed-native tree species planting) and naturally regenerating (NR) plots within degraded rainforest fragments, and in 17 less-disturbed benchmark (BM) rainforest plots in the Western Ghats, India. We assessed the effects of active restoration on the 11 indicators and tested the hypothesis that active restoration effects increase with isolation from contiguous and relatively intact rainforests. Active restoration significantly increased canopy cover, adult tree and sapling density, adult and sapling species density (overall and late successional), compositional similarity to benchmarks, and aboveground carbon storage, which recovered 14–82% toward BM targets relative to NR baselines. By contrast, tree height–diameter ratios and the proportion of native saplings did not recover consistently in actively restored forests. The effects of active restoration on canopy cover, species density (adult), late successional species density (adult and sapling), and species composition, but not carbon storage, increased with isolation across the fragmented landscape. Our findings show that active restoration can promote recovery of forest structure, composition, and carbon storage within 7–15 yr of restoration in degraded tropical rainforest fragments, although the benefits of active over passive restoration across fragmented landscapes would depend on indicator type and may increase with site isolation. These findings on early stages of recovery suggest that active restoration in ubiquitous fragmented landscapes of the tropics could complement passive restoration of degraded forests in less fragmented landscapes, and protection of intact forests, as a key strategy for conserving biodiversity and mitigating climate change.

Data from: Integrating population genetics to define conservation units from the core to the edge of Rhinolophus ferrumequinum western range

The greater horseshoe bat (<i>Rhinolophus ferrumequinum</i>) is among the most widespread bat species in Europe but it has experienced severe declines, especially in Northern Europe. This species is listed Near Threatened in the European IUCN Red List of Threatened Animals and it is considered to be highly sensitive to human activities and particularly to habitat fragmentation. Therefore, understanding the population boundaries and demographic history of populations of this species is of primary importance to assess relevant conservation strategies. In this study, we used 17 microsatellite markers to assess the genetic diversity, the genetic structure and the demographic history of <i>R. ferrumequinum</i> colonies in the western part of its distribution. We identified one large population showing high levels of genetic diversity and large population size. Lower estimates were found in England and northern France. Analyses of clustering and isolation by distance suggested that the Channel and the Mediterranean seas could impede <i>R. ferrumequinum</i> gene flow. These results provide important information to improve the delineation of <i>R. ferrumequinum</i> management units. We suggest that a large management unit corresponding to the population ranging from Spanish Basque country to northern France must be considered. Particular attention should be given to mating territories as they seem to play a key role in maintaining the high levels of genetic mixing between colonies. Smaller management units corresponding to English and northern France colonies must also be implemented. These insular or peripheral colonies could be at higher risk of extinction in a near future.

Data from: Genomic evidence for panmixia of eastern and western North American migratory monarch butterflies

Monarch butterflies are known for their spectacular annual migration in eastern North America, with millions of monarchs flying up to 4,500 kilometers to overwintering sites in central Mexico. Monarchs also live west of the Rocky Mountains, where they travel shorter distances to overwinter along the Pacific Coast. Monarch numbers have recently dwindled, and monarch migration may be on the brink of extinction. It is often assumed that eastern and western monarchs form distinct evolutionary units that require specific protection, but genomic studies to support this notion are lacking. We used a tethered flight mill to show that migratory eastern monarchs have greater flight performance than western monarchs. However, analyzing more than 20 million SNPs in 43 monarch genomes, we found no evidence for genomic differentiation between eastern and western monarchs, suggesting the existence of one panmictic migratory population. Our genomic analysis also showed identical and low levels of genetic diversity, and a lack of singleton alleles, indicating a shared history of decline of eastern and western monarchs. Gene expression analysis of a subset of candidate genes during active flight revealed differential gene expression related to non-muscular motor activity. Our results demonstrate that North American monarchs form one panmictic and declining population, and that differences in migration distance and destination are therefore likely driven by environmentally induced differential gene expression. Our study indicates that eastern and western monarchs do not form distinct genetic populations, suggesting that preservation of eastern monarchs could potentially rescue western migration and vice versa.
