• Abstract

  The Hoary fox (Lycalopex vetulus) is a small canid (2.5-4kg) endemic to the savannah of central Brazil. It is classified by IUCN as data deficient, not existing in the literature a detailed description of the estrous cycle of this species. The present study aims to characterize ovarian cyclicity in Lycalopex vetulus using non-invasive method: Extraction and measurement of fecal metabolite…

  Non-invasive monitoring of ovarian cyclicity in Lycalopex vetulus, AP.R

• Abstract

  The maintenance of viable populations of wild animals requires the conservation of their habitat, as well as knowledge of behavioral and physiological aspects of each species. Currently, there are a total of 130 known species of birds considered extinct in the wild, and only four of these can still be found in captivity. Among these species, the proportion of parrots is superior to any ot…

  Assessment of urofecal metabolites of steroid hormones in golden conure (Guaruba guarouba) inside and outside the breeding season, AP.R

• Abstract

  Captive husbandry and breeding plays an important role as auxiliary tools for species conservation. These tools enable the conduct of research with different species, adding fundamental knowledge for success of conservation projects. According ANDRIOLO (2007), in this context priority is given to studies such as feeding behavior, oriented reproduction to conservation of genetic variabilit…

  Non-invasive measurement of gonadal hormones metabolite concentrations in Ranfastides Droppings, AP.R

(Only some records are available in English at this moment)

• Abstract

  The control of reproduction in captive wild animals is a necessary means for the management of these populations. The methods used have to look for reversible alternatives, easy to use and free of undesirable side effects. This project aims to evaluate the efficiency of the application of a synthetic GnRH agonist as a suppressant of ovarian cyclicity in Callitrichidae and to confirm its r…
