Comparative Parasitology, 2005
Abstract A total of 1,294 goodeid fish representing 35 species collected from 51 localities in Mexico was examined for adult intestinal helminths. Sampling was conducted between September 2001 and December 2004. Ten helminth species were collected (4 digeneans, 2 cestodes, and 4 nematodes).

Environmental Biology of Fishes, 1984
Significant genic differentiation occurred in samples of a stream population of Goodea atripinnis(Goodeidae) from a 1 km segment of the Rio Teuchitlan, Jalisco, Mexico. The lack of obvious selection gradients and physical barriers to migration over such short distances suggests that stochastic factors (seasonal reductions in stream flow, behavior) are ...

Genetica, 1986
An allozyme survey of thirty-four loci from seventeen populations of the goodeid fish Goodea atripinnis was conducted to examine the extent of differentiation between continuous and isolated populations. Differentiation, based upon the Rogers genetic distance, among a group of populations isolated since the Pleistocene was no greater than that observed

Proliferation of oogonia and folliculogenesis in the viviparous teleost Ilyodon whitei (Goodeidae).
Journal of morphology, 2014Oogonial proliferation in fishes is an essential reproductive strategy to generate new ovarian follicles and is the basis for unlimited oogenesis. The reproductive cycle in viviparous teleosts, besides oogenesis, involves development of embryos inside the ovary, that is, intraovarian gestation.

Thirteen helminth species were recorded during a helminthological examination of 754 Girardinichthys multiradiatus (Meek) (Pisces: Goodeidae) collected from 20 localities in the upper Lerma River sub-basin on the highland plateau of Mexico. The study constitutes a complete and extensive inventory of the helminth parasites of this freshwater fish ...

The Biological Bulletin, 1940
In an introductory article on the reproductive cycle of Neotoca bilineata, an account was given of the breeding cycle of the female as observed in the laboratory (Mendoza, 1939). In this second paper of the series, a description is given of the changes which the ovarian soma undergoes during gestation.

Six helminth species were recorded during the helminthological examination of 35 specimens of the goodeid Xenotaenia resolanae from Arroyo Durazno, Jalisco, Mexico, a tributary of the Cuzalapa River. Helminth species identified included: 4 species of digeneans, i.e., Posthodiplostomum minimum (metacercariae), Clinostomum companatum (metacercariae ...

Chapalichthys pardalis is a viviparous fish, microendemic to the Tocumbo Region in the state of Michoacán, Mexico. Despite the peculiar type of reproduction of goodeid fish and their mother-embryo interaction, the effects on embryos induced by maternal exposure to aquatic xenobiotics are still unknown. The objective of the present work was to determine
