Genetic and morphological evidence cast doubt on the validity of Mexican troglobitic species of the Neotropical catfish genus Rhamdia (Siluriformes: Heptapteridae) [PDF]
, 2021 Four of the 7 species of Rhamdia present in Mexico stand out for being microendemic and also troglobitic, that is, for being restricted to their type-locality caves and for exhibiting a distinctive phenotype characterized by ocular reduction/loss and ...

Female mating preferences in blind cave tetras Astyanax fasciatus (Characidae, Teleostei). [PDF]
, 2006 The Mexican tetra Astyanax fasciatus has evolved a variety of more or less color- and eyeless cave populations. Here we examined the evolution of the female preference for large male body size within different populations of this species, either surface-

Conservation studies on groundwaters’ pollution: Challenges and perspectives for stygofauna communities [PDF]
, 2021 Assessing the effects of pollution in groundwaters is recently considered among the most relevant aims for subterranean biology; with this perspective, we aim to provide examples of the most relevant effects that pollution may cause on stygofauna ...

The biomimetic potential of novel adaptations in subterranean animals [PDF]
, 2023 Subterranean habitats can be considered harsh conditions with lack of light, low nutrients levels and constant high humidity. To thrive under such conditions, cave-adapted species have evolved a range of novel morphological, physiological and behavioural
