Subterranean ecosystems (comprising terrestrial, semi-aquatic, and aquatic components) are increasingly threatened by human activities; however, the current network of surface-protected areas is inadequate to safeguard subterranean biodiversity. Establishing protected for challenging. First, there technical obstacles in mapping three-dimensional with uncertain boundaries. Second, rarity endemism organisms, combined a scarcity taxonomists, delays accumulation essential biodiversity knowledge. Third, establishing agreements preserve requires collaboration among multiple actors often competing interests. This perspective addresses challenges preserving through areas. Even face uncertainties, we suggest it both timely critical assess general criteria protection implement them based on precautionary principles. To this end, examine status European discuss solutions improve their coverage ecosystems.

Caves, with their unique geologic and biological features, have inspired human imagination throughout history. From photography to movies, through comics, painting, poetry, subterranean ecosystems feature prominently in various forms of artistic expression, often incorporating scientific ideas or concepts. Integrating art science offers a powerful way convey the uniqueness importance organisms that inhabit ecosystems, emphasizing as providers key ecological cultural services. This, turn, would help promote conservation. We discuss realized unrealized connections between biologists artists, aiming achieve broader protection for ecosystems. showcase different depict environments, explain how each aligns conservation science, highlight mutual benefits artists researchers biology can derive from collaboration. In doing so, we pose two important questions: How effectively bridge divide scientists artists? And assess effectiveness enhancing communication about conservation? By addressing these questions, envision future where intersect safeguard rich diverse heritage.

Bats play an important role in ecosystem function, serving as a biocontrol agent of insects and pollination plants, hence the need to understand factors affecting their health performance. Infestation fungi has been identified potential threat populations mammals, especially bats, yet specific effects on wing morphology flight behavior remain understudied. In this study, swabs Pipistrellus pipistrellus bat wings were taken from carers around United Kingdom. For identification, samples exposed conventional PCR using fungal-specific primers amplify ribosomal DNA's internal transcribed spacer (ITS).

Abstract The Jamaican flower bat Phyllonycteris aphylla is categorized as Critically Endangered on the IUCN Red List. It endemic to Jamaica and formerly known only from Stony Hill Cave, where there are an estimated c. 500 individuals. Previously declared extinct twice, its rediscovery in 2010 at Cave marked new hope for conservation of this important species. Although little about ecology, species presumed be a cave-obligate rooster rely exclusively so-called hot caves, which defined by high ambient temperatures low air quality. In March–April 2023, we surveyed bats seven caves throughout Jamaica. At two these, Green Grotto Caves, St. Ann, Rock Spring Caverns, Mary, captured both male pregnant female P. . 24 aphylla, 66 Caverns.

Estimating population changes of bats is important for their conservation. Population estimates hibernating are often calculated by researchers entering hibernacula to count bats; however, the disturbance caused these surveys can cause arouse unnaturally, fly, and lose body mass. We conducted 17 in 9 caves from 2013 2018 used acoustic detectors document cave-exiting night following our surveys. predicted that flights (i.e., flying out then back into caves) Townsend's big-eared (Corynorhinus townsendii) western small-footed myotis (Myotis ciliolabrum) would be higher than on nights no Those two species, did not fly more 82% Nonetheless, activity was related a factor number × total time cave). produced parsimonious model predicting probability as function ambient temperature.
