Abstract Parasites are a strong selective force that can influence fitness‐related traits. The length of chromosome‐capping telomeres can be used to assess the long‐term costs of parasitism, as telomere loss accelerates in response to environme

Carotenoid pigments have myriad functions in fish, including coloration and immunity. The “carotenoid trade-off hypothesis” posits that dietary limitation of carotenoids imposes constraints on animals to allocate to one function at the expense of

Nestlings of many bird species are hosts to hematophagous ectoparasites. Parasitism of nestlings is usually sub‐lethal, but its effects can extend into the fledgling and adult stages. Nestling hosts lose enough blood to become anemic, but the effec

Sexual selection can result in exaggerated morphology that constrains locomotor performance. We studied the relationship between morphology and the tail-flip escape response in male and female rusty crayfish (Faxonius rusticus), a species in which ma

The ability to generate large closing forces is important for many animals. Several studies have demonstrated that bite or pinching force capacity is usually related to the linear dimensions of the closing apparatus. However, relatively few studies h

We present evidence suggesting that some male convict cichlids (Amatitlania siquia) in Lake Xiloa, Nicaragua engage in alternative reproductive tactics (ARTs). These putative ART males were smaller than typical parental males, displayed coloration si

Female convict cichlids (Amatitlania siquia) exhibit bright orange ventral coloration that males lack. The behavioral implications of this color are poorly understood, particularly in naturally occurring populations where female coloration could play

Vertebrate pigmentation is known to be influenced by oxidative stress, but few studies have tested the hypothesis that structural coloration can be similarly affected. We tested whether fish iridophores, which produce structural color using guanine s

Carotenoids may act as antioxidants under many circumstances. We examined the importance of carotenoids as antioxidants in the gonads of male convict cichlids (Amatitlania nigrofasciata), a species in which males lack the carotenoid-based breeding co
