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

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
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]
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.

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]
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.
