Reproductive biology of Octopus hubbsorum (mollusca: cephalopoda) along the central Mexican pacific coast
(2009)
The reproductive biology of Octopus hubbsorum Berry, 1953, was studied along the central Mexican Pacific from 1998 to 2000. In the majority of the months (15), the sex ratio was 1:1. The ratio of males to females decreased ...
Population and reproductive patterns of the Neotropical planarian Girardia capacivasa (Platyhelminthes, Tricladida), and the influence of seasonality on its life history
(Elsevier Gmbh, 2018-05)
The biology of Neotropical freshwater planarians (Platyhelminthes) is almost unknown compared with that of their Holarctic relatives. In this paper, we 1) studied the sequence of development of the reproductive system of ...
