Abstract The Hawaiian Islands are known to harbour a rich and diverse fauna of troglobionts (obligate subterranean species). To date, 74 obligate cavernicolous arthropod species have been documented from across the main islands, majority which were Hawaiʻi Island, mostly lava tubes Kilauea volcano, youngest volcano on island. A recent bioinventory Kipuka Kanohina tube system south-western side Mauna Loa revealed existence previously unknown cave-adapted species. Among them is first...
The Fern Cave System, developed in the western escarpment of Southern Cumberland Plateau Interior Low karst region Northeastern Alabama, USA, is a global hotspot cave-limited biodiversity as well home to largest winter hibernaculum for federally endangered Gray Bat (Myotis grisescens). We combined existing literature, museum accessions, and database occurrences with new observations from bioinventory efforts conducted 2018–2022 generate an updated list troglobiotic stygobiotic species...
The Diptera fauna of Ozark caves is fairly typical that found elsewhere in the United States east Great Plains. sphaerocerid Spelobia tenebrarum only troglobitic dipteran caves. Probable troglophiles include mycetophilid Macrocera nobilis, psychodids Psychoda spp., and phorid Megaselia cavernicola. tipulids commonly caves, such as Dactylolabis montana, Dolichopeza spp. Limonia are probably all trogloxenes, Trichoceridae Heleomyzidae. mycetophilids, Exechiopsis umbratica Rymosia sp., culicids...
Six new species of Collembola the family Arrhopalitidae are described from United States (Pygmarrhopalites leonardwoodensis sp. nov., P. plethorasari youngsteadtii buffaloensis shoshoneiensis and ashcraftensis nov.) caves in Missouri (2 spp.), Arkansas Nevada, Indiana, respectively. These taxa, which display varying degrees troglomorphy, compared with previously known bring total North America to 41.
We present the first summary of status and distribution Benton cave crayfish (Cambarus aculabrum). The range this endangered is limited to 4 sites globally (3 in County 1 Washington County, Arkansas). identity species at these based upon morphological genetic studies. identities inhabiting 2 additional remain undetermined. current population census 40 individuals. Threats are analyzed, subsequent conservation measures recommended. Habitat degradation remains a threat species, especially for...
The range of the single-site endemic cave crayfish, Cambarus tartarus, is expanded to an additional system (Long's Cave), but still restricted Spavinaw Creek watershed within Delaware County, Oklahoma. Censuses these 2 populations in 2001 and 2004 produced record high counts: 17 individuals January-Stansbury Cave 63 Long's Cave. Cave, with at least 52 species animals, most species-rich subterranean habitat Oklahoma date. Conservation activities are summarized. tartarus remains extremely...
Our study was done to determine if cave crickets (Ceuthophilus gracilipes gracilipes) are able transport dictyostelid cellular slime molds into and within caves. Large were captured from Pigeon Roost Cave in northwestern Arkansas. Crickets individually washed remove spores, fecal pellets collected aseptically the crickets. Five species of dictyostelids, assigned two genera (Dictyostelium Polysphondylium), recovered surface six crickets, a single (D. sphaerocephalum) one sample pellets. Since...
Five new species of scuttle fly are reported from caves in Nevada, USA, namely Aenigmatias bakerae Disney, Megaselia excuniculus M. krejcae folliculorum necpleuralis Disney and a female that can not be named until linked to its male.
The transition from carnivory to omnivory is poorly understood. ability feed at more than one trophic level theoretically increases an animal's fitness in a novel environment. Because of the absence light and photosynthesis, most subterranean ecosystems are characterized by very few levels, such that food scarcity challenge many habitats. One strategy against starvation expand diet breadth. Grotto Salamanders (Eurycea spelaea (Stejneger, 1892)) known ingest bat guano deliberately,...
This study updates the status, expands range, and summarizes conservation activities to date for bristly cave crayfish, Cambarus setosus. A new state record this crayfish is reported after its discovery at 2 sites in counties (Benton Independence counties, Arkansas). makes C. setosus fifty-eighth species known from Arkansas. also first of Salem Plateau Ozark Plateaus ecoregion; it was previously only Springfield Missouri. The range Missouri includes Barry, Christian, Dade, Greene, Jasper,...
The Alabama Cave Shrimp Palaemonias alabamae Smalley, 1961 is a federally endangered cave shrimp endemic to just four systems within and near the greater Huntsville metropolitan area in Madison County, USA. It one of two described atyid Interior Low Plateau karst region. Here we report discovery new population P. from Fern system western Jackson Alabama. We observed August 2018 an isolated pool base-level stream passage longest Two were during subsequent survey July 2019: same second main...
We report the observation of a female Ringed Crayfish (Orconectes neglectus) in berry from January-Stansberry Cave, Delaware Co., Oklahoma, USA.
