Phylogenetic evidence from freshwater crayfishes that cave adaptation is not an evolutionary dead‐end

Evolution, Volume 71, Issue 10, Page 2522-2532, October 2017., 2017
Abstract Caves are perceived as isolated, extreme habitats with a uniquely specialized biota, which long ago led to the idea that caves are “evolutionary dead‐ends.” This implies that cave‐adapted taxa may be doomed for extinction before they can diversify or transition to a more stable state.

Into the Darkness: Unveiling Unexpected Records of the Nonnative Millipede Prosopodesmus jacobsoni Silvestri, 1910 (Polydesmida: Haplodesmidae) in Brazilian Caves

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT This study expands the known distribution of the nonnative millipede Prosopodesmus jacobsoni in Brazil and reports its presence in cave environments for the first time in the country. Based on recently collected material and historical records, the species is shown to maintain stable populations in subterranean systems in the states of ...

Brazilian Troglophilic Biodiversity: a neglected fauna in conservation actions

Biota Neotropica
Abstract Subterranean or hypogean habitats, despite colonization filters, can harbor high biodiversity with unique fauna and significant endemism. Traditionally, this biodiversity is categorized into Trogloxenes (organisms using the hypogean realm as shelters and frequently exiting to complete their life cycle), Troglophiles (“facultative cave-dwellers”

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

Population Ecology, Volume 68, Issue 1, January 2026.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

Alone no more—Integrative taxonomy of New Zealand odd‐clawed spiders challenges the monotypy of Pianoa and Gradungula (Araneae: Gradungulidae)

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
Taxonomic revision of New Zealand Gradungulidae reveals unexpected northern South Island diversity through integrated molecular phylogenetics and targeted field sampling. Two new species formally described — Gradungula kahurangi sp. nov. and Pianoa civis sp. nov. — with revised male genitalia diagnoses for all three New Zealand genera.

Paecilaema batman, a new species of Brazilian troglophilous harvestman that exhibits a remarkable color patches variation (Opiliones: Cosmetidae) [PDF]

Zoologia (Curitiba), 2013
A new species of harvestman, Paecilaema batman, from Brazilian limestone caves of the state of Goiás, is described, and a remarkable intraspecific color patch variation is discussed. Paecilaema batman sp. nov. differs from other species of the genus by the following combination of features: chelicera similar in both sexes; prosoma without color patches;

Far From Roads, Challenges Arise: Unravelling Knowledge Gaps in the Occurrence of Cave‐Restricted Species on the African Continent

African Journal of Ecology, Volume 63, Issue 8, December 2025.
ABSTRACT Understanding patterns of biodiversity distribution is fundamental for ecology, biogeography, and conservation. However, persistent challenges arise from the inaccessibility of many regions and habitats. Subterranean environments, in particular, host highly distinctive and specialised faunal assemblages, yet their investigation is hindered by ...
