The recovery of immature oocytes followed by in vitro maturation, fertilization and culture (IVMFC) allows the rescue of biological material of great genetic value for the establishment of genetic resource banks of endangered species. Studies exist on sperm cryopreservation of endangered Mohor gazelle (Gazella dama mhorr), but no work has been carried out yet on oocyte collection, fertilization...

A jade-vermelha (Mucuna bennettii F. Muell, Fabaceae) é uma trepadeira exótica facilmente encontrada em vários pontos do Distrito Federal, usada como forma de ornamentação quadras e parques na região. Esse trabalho tem objetivo relatar pela primeira vez a ocorrência da cochonilha Coccus hesperidum L. (Hemiptera: Coccidae) M. bennettii. Amostras cochonilhas foram coletadas duas plantas situadas ...

Digitonthophagus gazella (F.) has been widely introduced to the New World and both natural dispersal and intentional releases continue. In this study, we compare a population of D. gazella from South Africa and from the island of Vieques, Puerto Rico, using amplified fragment length polymorphism (AFLP) analysis. Genetic diversity was found to be high in both South Africa (H = 0.3623) and Vieque...

A severe outbreak of infection with type O, aphthovirus occurred in the Ramot Yissakhar nature reserve (Israel) in April 1985, resulting in the death of about half of a population of some 3,300 mountain gazelles (Gazella gazella). A smaller outbreak occurred in the southern Golan nature reserve among about 6,500 gazelles. Both outbreaks were controlled by shooting gazelles in a buffer zone arou...

Population status, group composition and social organization of the Soemmerring's gazelle (Gazella soemmeringii) were studied at Awash National Park (ANP) and Alledeghi Wildlife Reserve (AWR) in 2000. Total count method was used to assess the population size of the gazelle. Thirteen routes, each route being two kilometres away from the other, were designated at AWR for the vehicle survey. Simil...
