BackgroundThe objective was to evaluate the procollagen type I N-propeptide (PINP), osteocalcin (OC), -crosslaps (-CTX), and parathyroid hormone (PTH) in relation to age and sex of Chlorocebus aethiops in captivity. ...

Salminus brasiliensis, a characin regionally named ‘dourado’ (meaning goldfish), is the biggest characid fish, this species is cited in a list of fishes that are vulnerable. The goal of the present work was to try to ...

The matrinch Brycon amazonicus, a commercially important freshwater fish resource, has no heteromorphic sex chromosomes so far described. In the present study, we performed a screening of sex-associated DNA markers in this ...

The knowledge of the sex ratio of threatened populations or species is pivotal since sub-optimal sex ratios can affect negatively the population growth and resilience. The vulnerable species, Tapirus terrestris, is rarely ...
