Reproductive Adaptations Among Viviparous Fishes (Cyprinodontiformes: Poeciliidae)

Evolution, 1978
Adaptations for placing a maximum number of mature offspring in the next generation fall between the two adaptive extremes of having either high reproductive rates and low survival rates or low reproductive rates and high survival rates. Among the fishes, both extremes have been realized; for example, the ling, Molva molva may produce 20-30 X 106 eggs ...

Pteridines in the skin of xiphophorine fish (Poeciliidae)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1977
1. 1. A comparative study of substances fluorescing at 365 nm found in the skin and fins of Xiphophorine fish was carried out by means of thin-layer chromatography and fluorometry. Groups of single xanthophores, xanthoerythrophores and melanophores were examined by means of micro cellulose thin layers. 2. 2.

EVOLUTION OF A TRIHYBRID UNISEXUAL FISH ( POECILIOPSIS , POECILIIDAE)

Evolution, 1974
A diploid all-female fish of the genus Poeciliopsis (Poeciliidae) inhabits the Rio Fuerte of northwestern Mexico. From both morphological and biochemical studies, it is clear that this form, designated P. monachalucida (Schultz, 1969), arose by hybridization between P. monacha and P. lucida. (Schultz, 1969; Vrijenhoek, 1972).

Life History of Brachyraphis rhabdophora (Pisces: Poeciliidae)

Copeia, 1993
We describe the life-history pattern of Brachyraphis rhabdophora from several Costa Rican locations. This species is nonsuperfetating, meaning that it carries only one brood of developing young at a time. They are also lecithotrophic (ovoviviparous), meaning that there is no evidence of maternal provisioning of the young after the eggs have been ...

Genome organization in Xiphophorus (Poeciliidae; Telostei)

Molecular and General Genetics MGG, 1982
Xiphophorus represents a valuable model for studying genomic contributions to neoplasia. For analyzing these contributions at the molecular level, basic information about the genome organization is a prerequisite. This study presents data on the organization and complexity of the genomes of three species of Xiphophorus, maculatus, variatus and helleri,

Superfetation in the viviparous fish Heterandria formosa (Poeciliidae)

Journal of Morphology, 2019
Abstract Heterandria formosa is a viviparous poeciliid native of the southeastern of United States of America. H. formosa exhibits unique reproductive features as: (a) production of extremely small eggs with scarce quantity of yolk (microlecithal eggs), (b) consequently, a high level of matrotrophy and development of a complex follicular placenta, (c ...

Meiosis in Triploid All-Female Fish ( Poeciliopsis , Poeciliidae)

Science, 1972
Prior to meiosis in triploid gynogenetic all-female forms of Poeciliopsis , the chromosome number of the nucleus of the triploid oogonium is raised endomitotically to hexaploid. Recombination does not occur; instead, a triploid ovum with a genetic complement identical to that of the mother is produced by two ...
