Diet and predation risk affect tissue and excretion nutrients of Trinidadian guppies: a field survey [PDF]
Scientific ReportsConsumers vary in their excretion of nitrogen and phosphorus, altering nutrient cycles and ecosystem function. Traditional mass balance models that focus on dietary and tissue nutrients have poorly explained such variation in excretion. Here, we contrast

Visual Lateralisation in Female Guppies Poecilia reticulata Demonstrates Social Conformity but Is Reduced When Observing a Live Predator Andinoacara pulcher [PDF]
Ecology and EvolutionLiving in groups offers individuals a way of reducing their risk of predation. Visual lateralisation, characterised as an asymmetry in eye use, may offer an additional advantage to group‐living animals by enabling them to manage two concurrent visual ...

Parasite diversity and ecology in a model species, the guppy (Poecilia reticulata) in Trinidad [PDF]
Royal Society Open Science, 2020 The guppy (Poecilia reticulata) is a model species in ecology and evolution. Many studies have examined effects of predators on guppy behaviour, reproduction, survival strategies, feeding and other life-history traits, but few have studied variation in ...

How did the guppy Y chromosome evolve?
PLoS Genetics, 2021 The sex chromosome pairs of many species do not undergo genetic recombination, unlike the autosomes. It has been proposed that the suppressed recombination results from natural selection favouring close linkage between sex-determining genes and mutations

Foraging innovation in the guppy [PDF]
Animal Behaviour, 1999 When novel behaviour patterns spread through animal populations, typically one animal will initiate the diffusion. It is not known whether such 'innovators' are particularly creative individuals, individuals exposed to the appropriate environmental contingencies, or individuals in a particular motivational state.

مجلة المختار للعلوم, 2021 This study was carried out to evaluate the growth response of guppy Poecilia reticulata to different dietary protein levels. A total of 72 fry of guppy fish of an initial body weight 0.365± 0.01g were distributed randomly into 60 L aquaria at the ...

Postcopulatory inbreeding avoidance in guppies [PDF]
Journal of Evolutionary Biology, 2014 AbstractIn many species, the negative fitness effects of inbreeding have facilitated the evolution of a wide range of inbreeding avoidance mechanisms. Although avoidance mechanisms operating prior to mating are well documented, evidence for postcopulatory mechanisms of inbreeding avoidance remain scarce.

Evolution of non-kin cooperation: social assortment by cooperative phenotype in guppies [PDF]
Royal Society Open Science, 2019 Cooperation among non-kin constitutes a conundrum for evolutionary biology. Theory suggests that non-kin cooperation can evolve if individuals differ consistently in their cooperative phenotypes and assort socially by these, such that cooperative ...

Copper sulfate acute ecotoxicity and environmental risk for tropical fish
Acta Scientiarum: Biological Sciences, 2014 The aim of this study was to estimate copper sulfate acute toxicity and to determine death percentage and environmental risk on guppy fish (Phallocerus caudimaculatus), zebrafish (Brachydanio rerio), mato grosso (Hyphessobrycon eques), and pacu ...
