Sex differentiation pattern in the annual fish Austrolebias charrua (Cyprinodontiformes: Rivulidae).
Sex differentiation process, determination of sexual strategy, and gametogenesis of the annual fish Austrolebias charrua are established. Evidence of histological sex differentiation in an antero-posterior gradient was observed in pre-hatching stages. Sexual strategy corresponds to the "differentiated gonochoric" pattern. Histological analyses of adult gonads showed an asynchronous spawning mod...
متن کاملFemale Annual Killifish Austrolebias reicherti (Cyprinodontiformes, Rivulidae) Attend to Male Chemical Cues
Chemical communication is an important mediator of social interactions in fish, including mate recognition, mate choice and intrasexual competition. We used a simultaneous-choice design to test the response of adult females of the annual killifish, Austrolebias reicherti, towards male-conditioned water, both crude and fractionated into its polar and non-polar components. Females preferred male-...
متن کاملComplete mitochondrial genome of a self-fertilizing fish Kryptolebias marmoratus (Cyprinodontiformes, Rivulidae) from Florida.
The complete mitochondrial genome was sequenced in a mangrove rivulus Kryptolebias marmoratus from western Florida using next-generation sequencing. The 17 329 bp-long genome was identical in length and 99.8% similar to a previously published genome of this species from a specimen of unknown geographic origin. Gene arrangement in K. marmoratus is similar to other cyprinodontiform fishes, except...
متن کاملKaryotype Patterns of Hypsolebias antenori (Cyprinodontiformes: Rivulidae): An Endangered Killifish of the Semiarid Region of Brazil
Annual fish which belong to the order Cyprinodontiformes constitute an excellent model for evolutionary studies. their short life cycle, distribution in ecologically dynamic environments, and low agility make them favorable for genetic analyses. The species Hypsolebias antenori (Rivulidae), encountered in seasonal pools located in the semiarid region of Northeastern Brazil, has been the object ...
متن کاملThe influence of temperature on the embryonic development of the annual fish Cynopoecilus melanotaenia (Cyprinodontiformes, Rivulidae).
The present study aims to provide data about the time required for Cynopoecilus melanotaenia kept at different temperatures to complete embryonic development. This information can be valuable for optimizing laboratory culture and facilitating future use of this species as a test organism in toxicity tests. Temperature effects on hatching rate are presented as well as information related to embr...
