Standing genetic variation as a potential mechanism of novel cave phenotype evolution in the freshwater isopod, Asellus aquaticus. [PDF]

Evol Dev, 2023
An orange eye phenotype, hidden within cave populations (masked by absence of pigment), was uncovered through crossing cave populations with surface populations. A similar orange eye phenotype can be found within surface populations suggesting that orange alleles within the cave populations originated from standing variation in the founding surface ...

Acadian biospeleology: composition and ecology of cave fauna of Nova Scotia and southern New Brunswick, Canada [PDF]

International Journal of Speleology, 2007
The vertebrate and invertebrate fauna, environment and habitats of caves and disused mines in Nova Scotia and southern NewBrunswick are provisionally catalogued and described, based on field collections made over many years. The area was glaciatedand the

Prefatory Arthropod biospeleology of Robber’s cave of Satara district of Maharashtra

Environment Conservation Journal
The present study aimed to document the preliminary arthropod fauna of the Robber’s Cave. The cavern vertebrate fauna is well documented, but the arthropod fauna has not been documented from the studied cave area.

Contrasting Approaches to the Study of Subterranean Life: Biospeleology and Speleobiology

Acta Carsologica, 2023
The study of subterranean life in general and cave life in particular has been given several names, most especially biospeleology and speleobiology. Historically, biospeleology came first, and signalled that biological study was part of speleology, the ...

Towards evidence-based conservation of subterranean ecosystems. [PDF]

Biol Rev Camb Philos Soc, 2022
ABSTRACT Subterranean ecosystems are among the most widespread environments on Earth, yet we still have poor knowledge of their biodiversity. To raise awareness of subterranean ecosystems, the essential services they provide, and their unique conservation challenges, 2021 and 2022 were designated International Years of Caves and Karst.

Genomic Comparisons of Alphacoronaviruses and Betacoronaviruses from Korean Bats [PDF]

Viruses, 2022
Coronaviruses are well known as a diverse family of viruses that affect a wide range of hosts. Since the outbreak of severe acute respiratory syndrome, a variety of bat-associated coronaviruses have been identified in many countries. However, they do not

At the confluence of vicariance and dispersal: Phylogeography of cavernicolous springtails (Collembola: Arrhopalitidae, Tomoceridae) codistributed across a geologically complex karst landscape in Illinois and Missouri. [PDF]

Ecol Evol, 2018
We assess the evolutionary history of two ecologically distinct groups of terrestrial cave‐dwelling springtails (Collembola) in the genera Pygmarrhopalites (Arrhopalitidae) and Pogonognathellus (Tomoceridae) that are codistributed in caves throughout the Salem Plateau—a once continuous karst region, now bisected by the Mississippi River Valley in ...

The role of isolation on contrasting phylogeographic patterns in two cave crustaceans [PDF]

BMC Evolutionary Biology, 2017
Background The underlying mechanisms and processes that prompt the colonisation of extreme environments, such as caves, constitute major research themes of evolutionary biology and biospeleology.

Hypogean Communities as Cybernetic Systems: Implications for the Evolution of Cave Biotas

Diversity, 2020
Ramón Margalef proposed in 1968 that ecosystems could be better understood if they were viewed as cybernetic systems. I tested this hypothesis in the case of hypogean ecosystems using available pieces of evidence. I looked on how information on feedbacks,

Dominant bacterial phyla in caves and their predicted functional roles in C and N cycle [PDF]

BMC Microbiology, 2017
Background Bacteria present in cave often survive by modifying their metabolic pathway or other mechanism. Understanding these adopted bacteria and their survival strategy inside the cave is an important aspect of microbial ecology. Present study focuses
