Spatial and temporal changes in invertebrate assemblage structure from the entrance to deep-cave zone of a temperate marble cave
Seasonality in surface weather results in seasonal temperature and humidity changes in caves. Ecological and physiological differences among trogloxenes, troglophiles, and troglobionts result in…
Chemolithoautotrophy supports macroinvertebrate food webs and affects diversity and stability in groundwater communities.
This work reevaluated the subterranean food web paradigm by examining spatial variation in the isotopic composition of basal food resources and consumers, food web structure, stygobiont species diversity, and chromophoric organic matter across a geochemical gradient in a large and complex groundwater system, the Edwards Aquifer in Central Texas.
The conservation status of Texas groundwater invertebrates

Compared to other regions, Texas’ groundwater fauna is not unique in terms of rarity and threat, suggesting that as an ecological group, groundwater-obligate species are probably among the world’s most imperiled taxa.
Morphological and trophic specialization in a subterranean amphipod assemblage
The results indicate that sympatric subterranean amphipod species can exhibit specialised feeding strategies, suggesting that competition among species is driving niche partitioning and contradict the assumption that variable resource availability in groundwater habitats selects for trophic generalists among sympatrics species.

ISSUE: Lot accession information from natural history collections represents a potentially vital source of large datasets to test biodiversity, biogeography and macroecology hypotheses. But does such…
Genetic Population Structure of the Madison Cave Isopod, Antrolana lira (Cymothoida: Cirolanidae) in the Shenandoah Valley of the Eastern United States
It is suggested that these clades remain at risk from anthropogenic disturbances such as urban development, and proposed that each of the clades be considered a distinct management unit in order to preserve the total genetic diversity for the species.
Life Cycles of Allocapnia recta and Leuctra spp. (Plecoptera: Capniidae and Leuctridae) Across a Flow Gradient in a Central Kentucky Karst Headwater Stream
Four species of stoneflies (Plecoptera) from an intermittent stream–perennial spring continuum were the subject of comparative life-cycle analyses, implying that L. alta demonstrated determinate voltinism.
Miktoniscus medcofi (Isopoda, Trichoniscidae) in Texas: a range extension for the genus and species
The occurrence of the terrestrial isopod Miktoniscus medcofi from a fen in Real County, Texas, represents a new state record for the species as well as a western range extension for the genus.
Ufocandona hannaleeae gen. et sp. nov. (Crustacea, Ostracoda) from an artesian well in Texas, USA
The discovery of this species from a deep artesian well contributes important information to the understanding of groundwater species diversity in a biologically diverse aquifer where the ostracod fauna has been unstudied.
