Female mate choice is often based on male traits, including signals or behaviors, and/or the quality of a male's territory. In species with obligate paternal care, where care directly affects offspring survival, females ...

Plumage coloration has long been studied as a sexually selected character. The tawny-bellied seedeater, Sporophila hypoxantha, is a sexually dichromatic species, with adult males the more colorful sex and juvenile males ...

This study investigates whether female sequential decisions on accepting or rejecting a courting male are based exclusively on the quality of the male present or are affected by the quality of potential mates. We used ...

The major histocompatibility complex (MHC) genes are one of the most suitable candidates for elucidating the genetic bases of mate choice in vertebrates, given the potential benefits in terms of immunocompetence that can ...

Selection favors females that make use of reliable information on the genetic quality of males, which affects mating decisions. Although studies have shown that females prefer dominant males, it may not be adaptive for ...

This study tested the preference of pintado catfish females (Pseudoplatystoma coruscans) for associating with well-fed or food-deprived males in simultaneous choice tests. Females were tested under three different treatments ...
