Hematology in ornamental discus fish Symphysodon discus from Amazonian, Brazil [PDF]

open access: yesBrazilian Journal of Biology
Symphysodon discus is known in the world of aquariums for its market value, beauty, and behavior. However, more substantial information about its physiology and biology must be available, which can hinder its development and maintenance in breeding ...

Functional trait plasticity diverges between sexes in African cichlids: A contribution toward ecological sexual dimorphism?

open access: yesEcology and Evolution, 2023
Phenotypic plasticity enables development to produce multiple phenotypes in response to environmental conditions. Plasticity driven variation has been suggested to play a key role in adaptive divergence, and plasticity itself can evolve.

Subordinate Fish Mediate Aggressiveness Using Recent Contest Information

open access: yesFrontiers in Ecology and Evolution, 2021
Memorizing dominance relationships can help animals avoid unwinnable subsequent contests. However, when competitive ability changes over time—for example, as a function of condition—it may be adaptive to “forget” these dominance relationships and for ...

Sensory Drive in Cichlid Speciation [PDF]

open access: yesThe American Naturalist, 2006
The role of selection in speciation is a central yet poorly understood problem in evolutionary biology. The rapid radiations of extremely colorful cichlid fish in African lakes have fueled the hypothesis that sexual selection can drive species divergence without geographical isolation.

The effect of social context and learning on aggression biases: consequences for the role of male-male competition in speciation and a field study in cichlid fish

open access: yesFrontiers in Ecology and Evolution
Male-male competition and female-female competition can play important roles in the origin and maintenance of phenotypic polymorphism and speciation. If territory owners bias aggression towards others of their own phenotype, rare male phenotypes will be ...

The Midas cichlid species complex: incipient sympatric speciation in Nicaraguan cichlid fishes? [PDF]

open access: yesMolecular Ecology, 2004
AbstractSympatric speciation is a contentious concept, although theoretical models as well as empirical evidence support its relevance in evolutionary biology. The Midas cichlid species complex (Amphilophus citrinellus,labiatus,zaliosus) from several crater lakes in Nicaragua fits several of the key characteristics of a sympatric speciation model.

Effects of different sampling intervals on apparent protein and energy digestibility of common feed ingredients by juvenile oscar fish (Astronotus ocellatus) - doi: 10.4025/actascianimsci.v34i2.10541

open access: yesActa Scientiarum: Animal Sciences, 2011
This study evaluated the apparent protein and energy digestibility of common feed ingredients (soybean meal, fish meal, wheat meal and corn) by juvenile oscars using two different sampling intervals (30 min. and 12h).
