Abstract Island-endemic arthropods are understudied species and likely to be highly threatened with extinction. Analysis of IUCN Red List assessments can used highlight important microhabitats requiring conservation for the effective management island-endemic arthropod biodiversity. We synthesized information on 296 assessed as Critically Endangered April 2024, geography islands which they endemic, broad threats face. These comprised 33 taxonomic orders, across an average 53% were limited entirely tiny, confined areas habitat: caves, high elevation areas, isolated pools or sea stacks. micro-refugia most utilized by crustaceans least myriapods. Caves habitats temperate where habitat degradation threatens crustaceans. On small tropical arachnids hexapods invasive species, refugia mostly in areas. Sea stacks appear from only island-endemics notable long-distance dispersal adaptation. None sustaining immediately climate change. Using interaction between life history, threats, it is possible generalize that (1) should targeted management, (2) could yield undescribed presumed-extinct species.

Understanding how species respond to human activities is paramount ecology and conservation science, one outstanding question being large-scale patterns in land use affect biodiversity. To facilitate answering this question, we propose a novel analytical framework that combines environmental niche models, multi-grain analyses, traits. We illustrate the capitalizing on most extensive dataset compiled date for butterflies of Italy (106,514 observations 288 species), assessing agriculture urbanization have affected biodiversity these taxa from landscape regional scales (3-48 km grains) across country while accounting its steep climatic gradients. Multiple lines evidence suggest pervasive scale-dependent effects Italy. While explained richness primarily at grains ≤12 km, idiosyncratic responses highlighted "winners" "losers" human-dominated regions. Detrimental emerged (3-km grain) (48-km scales, disproportionally affecting small with short flight curve. Human therefore reorganized biogeography Italian butterflies, filtering out poor dispersal capacity narrow breadth not only local assemblages, but also pools. These results global efforts neglecting risk falling their goals, even typically assumed persist natural areas (e.g., invertebrates). Our study confirms consideration spatial will be crucial implementing effective actions Post-2020 Global Biodiversity Framework. In context, applications proposed broad potential identify which mechanisms underlie change different scales.Comprendere come le specie rispondono alle attività umane è essenziale per la conservazione della biodiversità. Tuttavia, questo ambito, rimane poco chiaro il ruolo dei cambiamenti dell’uso del suolo su larga scala. Per contribuire colmare queste lacune, proponiamo un nuovo approccio analitico che combina modelli di nicchia ambientale, analisi diverse scale spaziali e tratti funzionali delle indagate.

Abstract Citizen science programs are becoming increasingly popular among naturalists but remain heavily biased taxonomically and geographically. However, with the explosive popularity of social media near-ubiquitous availability smartphones, many post wildlife photographs on media. Here, we illustrate potential harvesting these data to enhance our biodiversity understanding using Bangladesh, a tropical biodiverse country, as case study. We compared records extracted from Facebook those Global Biodiversity Information Facility (GBIF), collating geospatial for 1013 unique species, including 970 species 712 GBIF. Although most observation were toward major cities, more evenly spatially distributed. About 86% Threatened Facebook, whereas GBIF almost entirely Of Least Concern species. To reduce global shortfall, key research priority now is development mechanisms extracting interpreting data.

Abstract Most empirical research on biological shortfalls has focused vertebrate taxa. This is important given many species in poorly studied groups such as invertebrates, plants, and fungi are predicted to possess high conservation risk. Here, we focus Laboulbeniomycetes: a class of microfungi that understudied. We examined four shortfalls: Linnean (knowledge gaps diversity), Wallacean distributions), Latimerian persistence), the newly introduced Scottian assessments) shortfalls. The shortfall Laboulbeniomycetes hard predict due inconsistent description rates. Analysis distribution patterns indicates likely experience an extremely shortfall, with having highly disjunct known distributions. analysis shows over half (51%) have not been recorded >50 years, while group collective 100%, none 2454 described received IUCN threat assessment. suggest continued study natural history collections, expanded citizen science programmes, machine‐learning identification approaches tools for reducing knowledge both taxa more generally.

The tropics contain a vast majority of species, yet our understanding tropical biodiversity is limited. Here we combine species locality data from scientific databases and social media to examine the coverage by existing protected areas in Bangladesh identify priority for future expansion. Although cover 4.6% Bangladesh, only five (0.004% 1,097 species) are adequately represented, 22 entirely absent protected-area system, including seven threatened species. Our spatial prioritization identified comprising 39% mainly northeast southeast. most irreplaceable (top 10%) hill forests and, lesser extent, agricultural landscapes. findings inform conservation policies government order meet Kunming-Montreal Global Biodiversity Framework targets.
