1. Natural selection can generate correlated suites of phenotypic traits by acting independently on physiological and behavioural characters or mechanisms that exert pleiotropic actions. 2. Current theory, supported artificial studies, suggests stress responses are at least partially under genetic control covary in a predictable manner. Indeed, such as hormonal responsiveness may underlie variation behaviour, including consistent behaviours described temperament personality, with bolder,...
Aggressive contests probably occur in networking environments where information about fighting ability is conveyed both to an opponent and individuals peripheral the fight itself, bystanders. Our primary aim was investigate relative influences of eavesdropping prior social experience on dynamics aggressive Xiphophorus helleri. A bystander's witness encounter manipulated using clear, one-way mirror, opaque partitions. After watching (or not watching) initial contest, bystander encountered...
Fish behaviourists are increasingly turning to non-invasive measurement of steroid hormones in holding water, as opposed blood plasma.When some us met at a workshop Faro, Portugal, September, 2007, we realised that there were still many issues concerning the application this procedure needed resolution, including: Why do measure release rates rather than just concentrations steroids water?How does one interpret when dealing with fish different sizes?What merits measuring conjugated well free...
It is widely expected that physiological and behavioral stress responses will be integrated within divergent stress-coping styles (SCS) these may represent opposite ends of a continuously varying reactive-proactive axis. If such model valid, then response traits should repeatable also change in an manner along major axis among-individual variation. While there some evidence association between endocrine traits, few studies incorporate repeated observations both. To test this model, we use...
Winner and loser effects are defined as an increased probability of winning aggressive interaction at time T, based on victories T-1, T-2, etc., losing losses respectively. Prior theoretical work dominance hierarchy formation has demonstrated that when players not capable individual recognition, always produce a clear top-ranked (alpha) individual, but all other ranks in group remain unclear; whereas winner strict linear hierarchies which the rank each is clear. Paradoxically, however,...
[Cortisol is an important indicator of health and behavioral state in fishes, produced response to stressors including confinement, handling social conflict. An inherent difficulty measuring circulating cortisol the implementation invasive procedures that can be potent stressors. Recent studies show reliably quantified from fish holding water by placing individuals a small beaker for predetermined collection period. We investigated whether convict cichlid ( Amatitlania nigrofasciata ) mount...
A suite of correlated behaviors reflecting between-individual consistency in behavior across multiple situations is termed a "behavioral syndrome." Researchers have suggested that cause for the correlation between different might lie neuroendocrine system. In this study, we examined relationships aggressiveness (a fish's readiness to perform gill display its mirror image) and each boldness (the emerge from shelter), exploratory tendency approach novel learning performance probability...
The mangrove rivulus (Kryptolebias marmoratus) is one of two preferentially self-fertilizing hermaphroditic vertebrates.This mode reproduction makes an important model for evolutionary and biomedical studies because long periods selffertilization result in naturally homozygous genotypes that can produce isogenic lineages without significant limitations associated with inbreeding depression.Over 400 currently held laboratories across the globe show considerable amonglineage variation...
Investigations of communication networks in animals have focused primarily on determining whether extract information from peripheral contests (eavesdropping) or respond to the presence bystanders (audience effect). The possibility that an animal's response being watched might be context dependent, however, has been explored far less detail. This study investigated influence two contexts, exposure audiences different sexes and absence a nest, aggressive behavior interacting male Siamese...
The behavioural mechanisms and patterns of protandrous sex change in bluebanded gobies Lythrypnus dalli were investigated compared to the well‐described behaviour protogynous change. To do this, unisex groups males females established; anatomical changes recorded over a 42 day period as social status sexual phenotype determined. In all cases, status, rather than expression particular behaviour, accurately predicted final phenotype. Rates submissive but not aggressive predictive each discrete...
Many animals use information acquired from recent experiences to modify their responses new situations. Animals' decisions in contests also depend on previous experience: after victories individuals tend behave more aggressively and defeats submissively. Although these winner and/or loser effects have been reported for of different taxa, they only recently shown be flexible traits, which can influenced by extrinsic factors. In a mangrove killifish (Kryptolebias marmoratus), instance, lost an...
The mangrove rivulus Kryptolebias marmoratus and a closely related species are the world's only vertebrates that routinely self-fertilize. Such uniqueness presents model for understanding why this reproductive mode, common in plants invertebrates, is so rare vertebrates. A survey of 32 highly polymorphic loci >200 specimens from multiple locales Florida Keys, USA, revealed extensive population-genetic structure on microspatial micro-temporal scales. Observed heterozygosities were severely...
