Preference for cannibalism and ontogenetic constraints in competitive ability of piscivorous top predators. [PDF]
Occurrence of cannibalism and inferior competitive ability of predators compared to their prey have been suggested to promote coexistence in size-structured intraguild predation (IGP) systems.

Dietary overlap and selectivity among mountain steppe river fish in the United States and Mongolia
Lotic systems in mountain regions have historically provided secure habitat for native fish populations because of their relative isolation from human settlement and lack of upstream disturbances.

Neural activity patterns in response to interspecific and intraspecific variation in mating calls in the túngara frog. [PDF]
During mate choice, individuals must classify potential mates according to species identity and relative attractiveness. In many species, females do so by evaluating variation in the signals produced by males.
