Fig. 5 in Extremely Endangered Butterflies of Scattered Central European Dry Grasslands Under Current Habitat Alteration
Fig. 5. Genetic landscapes for three steppe butterflies, (a) C. briseis, (b) P. damon, (c) P. dorylas, based on residual COI genetic distances. Warmer colors show higher genetic distances among neighboring populations (barriers).
Fig. 1 in Extremely Endangered Butterflies of Scattered Central European Dry Grasslands Under Current Habitat Alteration
Fig. 1. Localities of the study species in Central Europe (AT, CZ, four federal states of DE, HU, SK), distinguishing recently occupied (color), recently (i.e., post- 2010) extinct (white), recently not inventoried (light gray), and (re)introduced (including failed attempts, dark gray) populations of C. briseis (circles), P. damon (triangles), and P. dorylas (stars). See text for comments on their much denser distribution in the region just a few decades ago. Species P. damon and P. dorylas are present also in the Austrian Alps (not displayed on the map), and a few more (sub)recent populations of the two species are expected in lowland eastern AT.

Phylogeographic analyses for the butterfly P. dorylas: (a) distribution range (shaded) with locations of samples colored and symbolized by COI BAPS groups, (b) TCS haplotype network, (c) Maximum Likelihood tree (COI + wingless). Branch labels show bootstrap values higher than 50%. Sequences in the network and the tree were assigned to geographical or political regions (described by the legend).

Habitat heterogeneity affects the thermal ecology of the federally endangered blunt-nosed leopard lizard 2019 data
<p>Global climate change is already contributing to the extirpation of numerous species worldwide, and sensitive species will continue to face challenges associated with rising temperatures throughout this century and beyond. It is especially important to evaluate the thermal ecology of endangered ectotherm species now so that mitigation measures can be taken as early as possible. A recent study of the thermal ecology of the federally endangered Blunt-Nosed Leopard Lizard (Gambelia sila) suggested that they face major activity restrictions due to thermal constraints in their desert habitat, but that large shade-providing shrubs act as thermal buffers to allow them to maintain surface activity without overheating. We replicated this study and also included a population of G. sila with no access to large shrubs to facilitate comparison of the thermal ecology of G. sila in shrubless and shrubbed populations. We found that G. sila without access to shrubs spent more time sheltering inside rodent burrows than lizards with access to shrubs, especially during the hot summer months. Lizards from a shrubbed population had higher midday body temperatures and therefore poorer thermoregulatory accuracy than G. sila from a shrubless population, suggesting that greater surface activity may represent a thermoregulatory tradeoff for G. sila. Lizards at both sites are currently constrained from using open, sunny microhabitats for much of the day during their short active seasons, and our projections suggest that climate change will exacerbate these restrictions and force G. sila to use rodent burrows for shelter even more than they do now, especially at sites without access to shrubs. The continued management of shrubs and of burrowing rodents at G. sila sites is therefore essential to the survival of this endangered species.</p>

Alignment of three Neomonachus tropicalis D-loop hypervariable region sequences (from USNM 100358, 102527, and 102534).: Explanation note: The Neomonachus schauinslandi sequence was used as a reference. Dots indicate identity to the reference. Differences are shown as the base change relative to the reference. Numbering starts at the first base after the primer closest to the 5' end. The X symbols indicate the break between the two amplicons that are approximately 200 bp apart. Sequences were generated from consensus sequences of 3–5 individual PCR product clones. Several products were cloned and sequenced from more than one amplicon to confirm that the differences observed were not DNA damage related or due to sequencing errors.

DMP: Endangered Species Analysis
<p>s research project is centered on a systematic analysis of endangered species, employing data provided by The International Union for Conservation of Nature (IUCN). The IUCN periodically evaluates species and publishes their conservation status in the Red List. Our analysis aims to address several key questions: What is the current number of species listed as endangered? How has this number changed over time? What geographical, natural, or national factors contribute to a higher incidence of endangered species? Furthermore, we seek to determine whether these factors can also predict future trends in the number of endangered species. By examining these questions, this project aims to deepen our understanding of the dynamics affecting endangered species and contribute to their conservation efforts.</p> <h2> </h2> <p>Research Questions:</p> <ul> <li>How many species are currently listed as endangered? <ul> <li>How many animals are endangered in certain continents/areas/countries?</li> <li>How many animals are endangered for a certain class (taxonomic rank; e.g., Mammalia)?</li> <li>What are the main threats for certain classes?</li> </ul> </li> <li>How has this changed over time? <ul> <li>How has the number of endangered and critical endangered animals changed over time?</li> </ul> </li> <li>Which geographical and natural characteristics predict higher numbers of endangered species? <ul> <li>How has endangerment developed across climate zones?</li> <li>What climate zone characteristics predict higher numbers of endangered species?</li> <li>Can these characteristics predict trends in the number of species?</li> </ul> </li> </ul>
Landscape features influencing gene flow and connectivity of an endangered passerine
<p>Effective exchange of individuals among populations (i.e. gene flow) is one crucial aspect to maintain genetic diversity and viability of populations, especially in the case of threatened species. Landscape composition and structure may facilitate or limit individual movement within and among populations. We used a landscape genetics (LG) approach to assess the connectivity patterns of the threatened Dupont's lark (<em>Chersophilus duponti duponti</em>), considering their genetic patterns and the landscape features associated with its gene flow in Spain. We analysed genetic structure and relatedness based on 11 species-specific polymorphic microsatellites on 416 Dupont's lark individuals sampled across peninsular Spain between 2017 and 2019, covering most of the European distribution of the species. To assess the relationship between the landscape configuration and the species gene flow, we estimated genetic distance at the individual level (<em>Dps</em>). Next, we built a set of environmental surfaces from two time points (1990 and 2018), based on factors (land use and topography) influencing individuals' movement. We then obtained resistance surfaces from an optimization process on landscape variables, and LG analyses were done for single and composite surface models for each year separately. Our findings from both time points demonstrate, for the first time, that scatter or mosaic structured vegetation composed by low agricultural and tree cover and high presence of sclerophyllous shrubs favoured Dupont's lark dispersal, while dense and continuous tree cover, as well as areas of intensive agriculture, were limiting factors. Our results suggest the importance of steppe habitat patches both for the species establishment and dispersal. Besides, our results provide key information to develop specific conservation measures, including focusing on conserving and restoring steppe habitats as scattered and/or mosaic structured vegetation that could warrant the connectivity and persistence of Dupont's lark populations.</p>
