Abstract Reptiles are often overlooked in conservation efforts. Hence, long‐term population data is unavailable, and evidence for effective actions that improve reptile habitat remains scarce most species. Here we used a before–after control–intervention (BACI) experiment to investigate the impact of basking bank creation on four co‐occurring species: European adder, barred grass snake, slow worm, viviparous lizard. Long‐term refuge monitoring at UK wildlife reserve allowed assessment before after modification. Only lizards were observed banks within 12 months construction. In subsequent years, snake observations increased near worms first time, while adder away from decreased banks. Our small‐scale BACI study suggests attracted snakes surrounding area, which saw corresponding increase sightings.

Variation in life histories influences demographic processes, from adaptive changes to population declines leading extinction. Among history traits, generation length offers a critical feature forecast species' trajectories such as (widely used by the IUCN Red List) and adaptability environmental change over time. Therefore, estimates of are crucial monitor stability or predict future highly threatened organisms, particularly amphibians reptiles, which among vertebrates for uncertainty impacts remains high. Despite its importance, reptiles is largely missing. Here, we aim fill this gap modeling lengths amphibians, squamates testudines function species size, climate, phylogeny using generalized additive models phylogenetic least squares. We estimated 5059 (57%) 8722 (73%) 117 (32%) testudines. Our performed well most families (e.g. Bufonidae Lacertidae Colubridae squamates, Geoemydidae testudines) while found high around prediction few families, notably Chamaeleonidae. Species' body size mean temperature were main predictors all groups. Although our not meant substitute robust validated measurements field studies natural museums, they can help reduce existing biases conservation assessments until data comprehensively available.

The global environmental crisis has reinforced the importance of improving documentation geographical distributions extant species. With this aim, species inventories specific locations or regions are a high priority, especially so in poorly explored areas. Cabinda Province, an Angolan enclave located between Republic Congo and Democratic (DRC), represents one most enigmatic areas Africa. No detailed within its protected (namely, Mayombe National Park) exist. Furthermore, region presents some better preserved remanent primary moist rainforest West Although these forests severely threatened by logging rapid social growth area. Therefore, we provide here first herpetological checklist Park Angola, to shed light on underexplored corner To obtain accurate identification, performed morphological examinations DNA barcoding identifications. As result, recorded total 76 amphibians reptiles area, including four new genera, 19 distribution records for 13 candidate This work also provides novel topotypic genetic material from three reptile (i.e., Agama congica, Panaspis cabindae Atractaspis congica), that may contribute revise solve taxonomic inconsistencies different groups. Finally, identified richness, as well with number habitat specialists, thus indicating more vulnerable extinction. our study allowed us identify special interest conservation amphibians, primarily focus extinction, but knowledge gaps still need further investigation. conclude, not only contributes improved understanding herpetofauna, highlights western slope Central Africa important biodiversity hotspot, centre endemism potential source diversification group land vertebrates.

Abstract The world is facing a biodiversity crisis, and species are in danger of slipping towards extinction before having their conservation status formally determined. Australian squamates (snakes lizards) form highly diverse (over 1000 species) fauna, with 12% being either Data Deficient or Not Evaluated. We examined attributes categorized as Evaluated compared key traits that linked threatened categories via univariate multivariate models. further used the machine learning model Caetano et al. (2022, PloS Biology, 20, e3001544) to predict putative risk for squamate based on an analysis reptiles globally. found often lacking information drivers threat distribution, but not intrinsic uncertain taxonomy. Deficient, possess similar traits, including small range sizes, insular endemics recently described, indicating they may require some management. Meanwhile, exhibit certain unique relative evaluated species. predicted 21% which three times greater than currently assessed (7%). This indicate larger proportion poorly known more likely be previously thought. Overall, our findings provide important resource management by highlighting missing data, well providing list should prioritized research.

The expanding use of community science platforms has led to an exponential increase in biodiversity data global repositories. Yet, understanding species distributions remains patchy. Biodiversity from social media can potentially reduce the knowledge gap. However, practical guidelines and standardized methods for harvesting such are nonexistent. Following privacy protection safeguards, we devised a method extracting distribution records Facebook groups that allow access their data. It involves 3 steps: group selection, extraction, georeferencing record location. We present how structure keywords, search photographs, georeference localities records. further highlight some challenges users might face when suggest solutions. our proposed framework, case study on Bangladesh's biodiversity-a tropical megadiverse South Asian country. scraped nearly 45,000 unique georeferenced across 967 found median 27 per species. About 12% were threatened species, representing 27% all also obtained 56 DataDeficient Bangladesh. If carefully harvested, significantly gaps. Consequently, developing automated tool extract interpret is research priority.

Abstract Species are the most commonly used unit of biogeography research, and in many conservation schemes. For faunal groups, taxonomy is a constant state flux, with new species being described, our concept existing regularly refined. Using diverse lineage Australian lizards (460+ species), skinks (Family Scincidae), we quantified impacts taxonomic changes over time on understanding richness, endemism beta diversity. We generated surfaces diversity from four editions (1975, 1988, 2000, 2014) an authoritative field guide to understand how shifts, enhanced biogeographic knowledge, influenced inferred patterns skinks. The number recognized skink has increased 2.3‐fold since 1975. Wet Tropics was major hotspot for (mostly locally endemic) additions. Hotspots richness remained broadly similar time, but some important local hotspots shifted. Endemism were weakly associated additions except Tropics. shifts patterns, which not changes, resulted better knowledge distributions through time. hypothesize that effects found generalize across clades regions—especially away research hotspots. suggest impact priorities particular regions groups needed.

Abstract In animals, the success of particular lineages can be measured in terms their number species, extent geographic range, breadth habitats and ecological niches, diversity morphological life‐history traits. Here, we review distribution, ecology, morphology life history skinks, a diverse lineage terrestrial vertebrates. We compared key traits between three subfamilies skinks non‐scincid lizards. There are currently 1743 described species skink, which represent 24% global lizard diversity. Since 2010, 16% descriptions have been skinks. The centres skink Australia, New Guinea, southeast Asia, Oceania, Madagascar central Africa. Compared with lizards, larger distributional ranges, but smaller body sizes. Sexual size dimorphism is rare Almost quarter (23%) exhibit limb reduction or loss, just 3% Skinks more likely to viviparous (34% species) non‐scincids (13%), higher clutch/litter sizes than non‐scincids. Although mature later non‐scincids, longevity similar that exhibited by other groups. Most (88%) active foragers, they carnivorous diurnal cathemeral groups, generally lower field temperatures appears both result them hitting upon winning plan capacity regularly deviate from this adapt ecology (e.g. repeated transitions viviparity) prevailing conditions.
