A synthesis of ecological data available for subterranean fishes throughout the world is
presented, and comparatively analyzed in an evolutionary context. Methods of ecological …

The evolution of hypogean fauna in general and hypogean fishes in particular has been
controversial. Explanations regarding the reduction or loss of phenotypic characters such as …

Notable progress in the biological sciences is occasionally made possible by the discovery
of a species that exhibits a specialized way of life, but nevertheless will thrive and breed in …

A diverse group of animals has adapted to caves and lost their eyes and pigmentation, but
little is known about how these animals and their striking phenotypes have evolved. The …

There are at least 86 species of troglomorphic fishes belonging to 18 families. Some of those
families are characterized by features that can be labeled as preadaptations to the …

We investigated differentiation processes in the Neotropical fish Astyanax that represents a
model system for examining adaptation to caves, including regressive evolution. In …

We studied the development and evolution of craniofacial features in the teleost fish,
Astyanax mexicanus. This species has an eyed surface dwelling form (surface fish) and …

Introgressive hybridization may play an integral role in local adaptation and speciation
(Taylor and Larson, 2019). In the Mexican tetra Astyanax mexicanus, cave populations have …

The evolutionary mechanisms responsible for the loss of eyes in cave animals are still
unresolved. Hypotheses invoking natural selection or neutral mutation have been advanced …

The population ecology of the trichomycterid catfish, Trichomycterus itacarambiensis, from
the Olhos d'Àgua Cave, Itacarambi Co., Minas Gerais, eastern Brazil, was investigated by …
