Experimental transplants are a particularly effective way of assessing the significance of natural selection in the wild and have been successfully employed in the past to determine how the colour patterns and life histories of guppies, Poecilia reticulata, in Trinidad, evolve in response to predation. In this paper we investigate an existing inter-drainage transplant of guppies, undertaken by C. P. Haskins in 1957, to ascertain whether a change in predation pressure also leads to changes in…

Genetic consequences of an artificial introduction of guppies (Poecilia reticulata) in N. Trinidad
TLDR
There is strong evidence that the enzyme loci studied here are selectively neutral in the face of selection pressures known to have modified behaviour since the introduction of intraspecific fish.

An investigation of the behaviour of guppies, Poecilia reticulata, in the wild reveals that sexual conflict varies markedly in different habitats. Males from high-predation sites in Trinidad (where
Experimental studies of evolution in guppies: a model for understanding the evolutionary consequences of predator removal in natural communities
TLDR
It is argued that predator re‐introductions might be destabilizing if, in the absence of predators, their prey have evolved in a fashion that makes them highly susceptible to predation, even after time intervals as short as 50–100 years.
The behavioural ecology of the Trinidadian guppy, Poecilia reticulata, as an invasive species
This thesis focuses on the guppy, Poecilia reticulata, as an invasive species. Its nonnative distribution, the biology behind its success and the reasons for its introduction are examined. A
Population differences in the schooling behaviour of the Trinidad guppy, Poecilia reticulata: adaptation or constraint?
TLDR
The behaviour of guppies from populations in two Trinidad drainages is document and it seems unlikely that reduced pre- predation risk is unlikely at both sites.
RAPID EVOLUTION OF ESCAPE ABILITY IN TRINIDADIAN GUPPIES (POECILIA RETICULATA)
TLDR
Analysis of Trinidadian guppies found rapid evolutionary loss of escape ability in populations introduced into low‐predation environments, suggesting that steep fitness trade‐offs may influence the evolution of escape traits.
Reasons for the Invasive Success of a Guppy (Poecilia reticulata) Population in Trinidad
TLDR
Evidence is presented that behavioural traits such as shoaling and mate choice can promote population mixing if individuals do not distinguish between native and foreign conspecifics, and that introduced fish are likely to benefit from the protection of a shoal and will improve their survival chances as a result.
Enemy within the gates : reasons for the invasive success of a guppy population (Poecilia reticulata) in Trinidad
TLDR
Investigation of how different population traits shaped the outcome of Haskins's introduction of Guanapo river guppies into the Turure river found no obvious differences between invasive and native populations, and opposes the recent split of the guppy into two different species following drainage system borders.
Predator Inspection Behaviour Covaries With Schooling Tendency Amongst Wild Guppy, Poecilia Reticulata, Populations in Trinidad
TLDR
There is a strong correlation between schooling tendency and the group sizes adopted by guppies inspecting a realistic model predator, and it seems unlikely that many of these fish were caught in a Prisoner's Dilemma.
Predation risk and alternative mating tactics in male Trinidadian guppies (Poecilia reticulata)

TLDR
The results are the first to confirm risk-sensitive mating behaviour in free-ranging male guppies within a population, and demonstrate the potential importance of predators in influencing the relative use of alternative mating tactics in this species on a microgeographical scale in the wild.

Life History Evolution in Guppies: III. The Impact of Prawn Predation on Guppy Life Histories
TLDR
Gppy life history traits are sensitive to size-specific predation and are used here to indicate the importance of Macrobrachium as predators of mature guppies.
THE IMPACT OF PREDATION ON LIFE HISTORY EVOLUTION IN TRINIDADIAN GUPPIES (POECILIA RETICULATA)
TLDR
Empirical studies have sought correlations between life histories and potential sources of demographic selection and, in some cases, have attempted to determine if the organisms have evolved as predicted by theory, but few have achieved either goal.
Variation in Schooling and Aggression Amongst Guppy (Poecilia Reticulata) Populations in Trinidad
TLDR
Results point towards a trade-off between antipredator behaviour and resource defence and confirm that schooling has associated costs as well as benefits.

TLDR
Until the authors know more about how and why natural selection occurs, attempts to measure it are quixotic, and discussions of its importance are theandric.
Marked genetic divergence revealed by allozymes among populations of the guppy Poecilia reticulata (Poeciliidae), in Trinidad
TLDR
Populations of the guppy Poecilia reticulata from six locations in N.E. Trinidad were examined by starch gel electrophoresis to estimate their degree of genetic divergence, and patterns of population differentiation are discussed in relation to probable past geological and historical events, and present-day evolutionary forces.
Experimentally induced life-history evolution in a natural population
TLDR
The findings of a long-term study of guppies are reported, in which the predictions of life-history theory are supported, and it is proved that predation caused this pattern, by changingpredation against adults to predation against juveniles.
The adaptive significance of schooling as an anti-predator defense in fish
TLDR
Schooling may not be an equally appropriate defence against all predators and the phylogenetic origins of populations or species can lead to additional genetic constraints, so behavioural ecologists will increasingly focus on how interactions between such con straints govern the evolution of behaviour.
THE INHERITANCE OF CERTAIN COLOR PATTERNS IN WILD POPULATIONS OF LEBISTES RETICULATUS IN TRINIDAD
TLDR
The males of Lebistes form one of the most highly polymorphic color series known in nature, in sharp contrast to the monotonous phenotypic uniformity of the females.
