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

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 ...

The Guppy Effect as Interference [PDF]
, 2012 People use conjunctions and disjunctions of concepts in ways that violate the rules of classical logic, such as the law of compositionality. Specifically, they overextend conjunctions of concepts, a phenomenon referred to as the Guppy Effect. We build on

GuPPy, a Python toolbox for the analysis of fiber photometry data
Scientific Reports, 2021 Fiber photometry (FP) is an adaptable method for recording in vivo neural activity in freely behaving animals. It has become a popular tool in neuroscience due to its ease of use, low cost, the ability to combine FP with freely moving behavior, among ...

ESTs and EST-linked polymorphisms for genetic mapping and phylogenetic reconstruction in the guppy,
BMC Genomics, 2007 Background The guppy, Poecilia reticulata, is a well-known model organism for studying inheritance and variation of male ornamental traits as well as adaptation to different river habitats.

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 ...

Nature Communications, 2021 Male colour patterns of the Trinidadian guppy (Poecilia reticulata) are typified by extreme variation governed by both natural and sexual selection. Since guppy colour patterns are often inherited faithfully from fathers to sons, it has been hypothesised

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.
