Spatial conservation prioritization for the Amur tiger in Northeast China
<p class="Paragraph">Amur tiger (<i>Panthera tigris altaica</i>) is critically endangered and also the subspecies of the tiger with the most restoration potential in China. It is challenging to protect large-ranging carnivores like tigers under increasing pressure of human development. To provide a more technically robust foundation for tiger habitat conservation prioritization, we conducted a comprehensively empirical analysis based on a broadly collected occurrence dataset of tigers and their prey. We modeled tiger distribution by running an ensemble model integrating nine different algorithms. We found that the ensemble model performed well and outperformed any individual model regarding the discrimination ability. We used cumulative resistant kernel analysis to identify core habitats as with high predicted movement density and used factorial least-cost paths to model corridors among tiger occurrence locations. We found core habitats for Amur tigers are distributed in three mountain areas, namely eastern Wanda Mountain, southern Zhangguangcailing, and Laoyeling-Dalongling. We found significant protection gaps as existing protected areas only cover less than 1/4 of predicted core habitats, but this proportion will rise significantly with the establishment of the Northeast China Tiger and Leopard National Park. Furthermore, we ranked spatial priorities for the expansion of the protected area network, simultaneously considering biological and socioeconomic dimensions under the Zonation framework. Our study presented the most up-to-date and detailed maps of the predicted potential distribution and area of the most important habitats for the Amur tigers in China, which can provide quantitative guidance in the effort to maximize the efficiency of conservation initiatives at a regional scale.</p>

High diversity of mites (Acari: Oribatida, Mesostig-mata) supports the high conservation value of a broadleaf forest in Eastern Norway
<p>Broadleaf forests are critical habitats for biodiversity and this biodiversity is in turn essential for their proper functioning. Mites (Acari) are a numerous and functionally essential component of these forests. We report the diversity of two important groups, Oribatida and Mesostigmata, in a broadleaf forest in Eastern Norway which is considered to be a biodiversity hotspot. Eighteen samples, each 500 cm<sup>3</sup>, were collected from diverse microhabitats (moss on ground, lichens on tree twigs lying on ground, moss on tree trunk at ground level and 1.5 m above ground, moss on decaying wood, log and stump, and decaying wood) from which 10,843 specimens and 95 species from 32 families of Oribatida, and 655 specimens of 34 species from 14 families of Mesostigmata were found. Only 30% of the species were previously recorded in broadleaf forests in Western Norway. Oribatid communities on tree stumps and in lichens were distinct from the other communities, while mesostigmatid communities on tree trunks (both at ground level and above ground) and in lichens differed most from other communities. Over 30% of the species were found in only a single microhabitat. Twenty-three species and the genus <i>Zerconopsis</i> are reported from Norway for the first time. Six records are also new to Fennoscandia, including (Oribatida) <i>Quadroppia monstruosa</i>,<i> Eueremaeus valkanovi</i>,<i> Ramusella furcata</i>,<i> </i>and (Mesostigmata)<i> D</i><i>endrolaelaps rectus</i>,<i> D</i>.<i> multidentatus</i>,<i> </i>and<i> D</i>.<i> tenuipilus</i>. In addition, several rare species were detected, e.g., <i>Achipteria magna</i>, <i>Oribotritia berlesei</i>,<i> </i>and <i>Subiasella quadrimaculata</i>, and two were found in their northernmost locality (<i>O</i>.<i> berlesei</i>,<i> E</i>.<i> valkanovi</i>). These results confirm the unique character and high conservation value of the studied forest in Norway, Fennoscandia and at a European scale.</p>

Data from: Coalescence times, life history traits and conservation concerns: an example from four coastal shark species from the Indo-Pacific
<p><span><span><span><span><span><span><span><span><span><span><span>Dispersal abilities play a crucial role in shaping the extent of population genetic structure, with more mobile species being panmictic over large geographic ranges and less mobile ones organized in meta-populations exchanging migrants to different degrees. In turn, population structure directly influences the coalescence pattern of the sampled lineages, but the consequences on the estimated variation of the effective population size<i> </i>(<i>Ne</i>) over time obtained by means of <i>unstructured</i>demographic models remain poorly understood. However, this knowledge is crucial for biologically interpreting the observed <i>Ne </i>trajectory and further devising conservation strategies in endangered species. Here we investigated the demographic history of four shark species (<i>Carharhinus melanopterus</i>, <i>Carharhinus limbatus</i>, <i>Carharhinus amblyrhynchos</i>, <i>Galeocerdo cuvier</i>) with different degrees of endangered status and life history traits related to dispersal distributed in the Indo-Pacific and sampled off New Caledonia. We compared several evolutionary scenarios representing both <i>structured</i> (meta-population) and<i> unstructured</i> models and then inferred the <i>Ne</i> variation through time. By performing extensive coalescent simulations, we provided a general framework relating the underlying population structure and the observed <i>Ne</i> dynamics. On this basis, we concluded that the recent decline observed in three out of the four considered species when assuming <i>unstructured</i> demographic models can be explained by the presence of population structure. Furthermore, we also demonstrated the limits of the inferences based on the sole site frequency spectrum and warn that statistics based on linkage disequilibrium will be needed to exclude recent demographic events affecting meta-populations.</span></span></span></span></span></span></span></span></span></span></span></p>
