This study's main objective was to determine how mortality patterns mold the life histories of natural populations of guppies (Poecilia reticulata) in the Northern Range of Trinidad. These populations are exposed to differences in both the intensity and mode of predation. The three types of localities considered in this study include: (1) Crenicichla localities, where guppies co-occur with Cited by: Reasons for the Invasive Success of a Guppy (Poecilia reticulata) Population in Trinidad Caya Sievers1*, Eva-Maria Willing2, Margarete Hoffmann2, Christine Dreyer2, Indar Ramnarine3, Anne Magurran1 1Scottish Oceans Institute, University of St. Andrews, St. Andrews, Fife, United Kingdom, 2Department of Molecular Biology, Max Planck Institute for DevelopmentalCited by:
The present study examines the effects of inbreeding and crossing on various quantitative traits in the guppy, Poecilia s of inbreeding and crossing were examined in six quantitative traits; body length at birth, survival at day , undwarf rate at day , body length at day , salinity tolerance and high temperature by: Change Log. 11/20/ Added collection data to species maps.; 11/15/ Added collection data to species maps.; 09/20/ Started caching Fish Net 2 data.

Studies on natural populations of Trinidadian guppies reported on geographical variation in morphological, behavioral and life history characteristics, primarily explained by variation in predator regimes (Magurran et al. ; Magurran ). Within few generations after the exposure to an experimentally altered predator regime, guppyCited by:
Guppy. The guppy (also known as the millionfish) is a small colourful species of freshwater tropical fish that is found naturally in the rivers and lakes of South America. There are nearly different types of guppy spread throughout Barbados, Brazil, Guyana, Netherlands Antilles, Trinidad and Tobago, and Venezuela.. The guppy is one of the most popular types of aquarium tropical fish in the Scientific name: Poecilia Reticulata. The guppy (Poecilia reticulata) is an important model organism in ecological genetics. Adaptation of guppies to contrasting upland and lowland habitats has been extensively studied with respect to behavior, morphology and life history. The proportions of guppies having different traits within a population change. Successful behaviors learned by certain guppies are passed on to offspring. Mutations occur to meet the needs of the guppies as the environment changes. (n=) Primary Sources: Endler JA. Natural selection on color pattern in Poecilia reticulata.

Here, we study temporal variation at the MHC class IIB gene in nine wild populations of the guppy (Poecilia reticu-lata). The guppy is a tropical freshwater fish native to north-east South America and the neighboring islands of Trinidad and.
