Mating behavior and time budget of an androdioecious crustacean, , (Crustacea: Conchostraca)is species are either hermaphroditic or male, a relatively rare mating system for animals known as androdioecy. Comparison of sex ratios between four neighboring populations of . in Southern New Mexico showed wide variation in the ratio of males to hermaphrodites with males making up as much as 42%

Selfing versus outcrossing in the androdioecious clam shrimp, , (Crustacea, Conchostraca)maphrodites. Outcrossing is maintained within most populations of this species despite the high genetic cost of sex, suggesting that compensating factors provide an advantage to outcrossing. We hypothesized that one such benefit would be the production of larger clutch sizes resulting from outcrosse

Evidence for sex-related differences in phototactic behaviour of , (Crustacea: Anostraca)n females. This was also evident when colour filters were used. Females only became little less negatively phototactic under yellow light, whereas males showed a strong positively phototactic response. The response to the positioning of a yellow filter was stronger than to the use of a red or blue f

The description and preliminary prediction of the inundation pattern in a temporary habitat of Anostill be wet, how often this occurs, for what period each inundation lasts and what variability there is in this pattern. For logistic reasons one cannot follow each inundation in a pan for the ten years or more needed to establish a pattern. Based on the available inundation data for two seasons at B

Review of Colombian Conchostraca (Crustacea) — ecological aspects and life cycles — family Cyclesthey found in parthenogenically reproducing populations which produce large, directly developing nondiapause eggs. But periodically and under certain environmental conditions, sexually reproducing generations appear and produce diapause eggs. The sexual generations include males and particularly consti
