Karyotype 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 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 کاملReproductive strategies of two Neotropical killifish, Austrolebias vandenbergi and Neofundulus ornatipinnis (Cyprinodontiformes: Rivulidae) in the Bolivian Gran Chaco.
The dry Chaco, a semiarid thorn forest, is experiencing some of the highest deforestation rates globally, coupled with the fact that small-bodied fish are at the highest risk of extinction, the killifish inhabiting this region may be some of the most threatened taxa. Yet, aspects of ecology and life history for Neotropical killifishes in the Bolivian Gran Chaco region are completely lacking, an...
متن کاملA new species of inseminating seasonal killifish of the Cynopoecilus melanotaenia complex from southern Brazil (Cyprinodontiformes: Rivulidae).
BACKGROUND The Cynopoecilus melanotaenia complex is a morphologically homogeneous killifish group, endemic from an area encompassing southern Brazil and northeastern Uruguay. It presently comprises four valid species: C. melanotaenia, the type species of the genus, and C. fulgens, C. intimus, and C. nigrovittatus. NEW INFORMATION Cynopoecilus feltrini, n. sp., from the lower Tubarão river bas...
متن کاملConservation status of an endangered annual fish Hypsolebias antenori (Rivulidae) from Northeastern Brazil.
This work presents information regarding the biology and state of conservation of an endangered annual fish Hypsolebias antenori. Fish were captured from small seasonal pools located in Northeastern Brazil. The total body length, body mass, sex ratio, first sexual maturity were investigated. The sampled population showed sexual dimorphism. There was a predominance of females (60%) over males (4...
