Minimally invasive hysterectomy in Coatis ( Nasua nasua )

Some wildlife species, such as coatis, have a high degree of adaptability to adverse conditions, such as fragmented urban forests, increasingly common on the world stage. The increase in the number of these mesopredators causes drastic changes in the communities of smaller predators, interferes with reproductive success of trees, as well as becoming a form of exchange between domestic and wild areas, favoring the transmission of zoonosis and increasing the occurrence of attacks to animals or people. This report describes the use of minimally invasive hysterectomy in two individuals of the species Nasua nasua, which can be accomplished through the use of hook technique, commonly used to castrate dogs and cats. The small incision and healing speed of incised tissues are fundamental in wild life management since the postoperative care is limited by the behavior of these animals. This technique proved to be effective and can greatly reduce the morbidity of this procedure in coatis

Predação de ninhos de Trachemys dorbigni (Duméril & Bibron) (Testudines, Emydidae) no extremo sul do Brasil Nest predation of Trachemys dorbigni (Duméril & Bibron) (Testudines, Emydidae) in Southern Brazil

Ninhos da tartaruga tigre-d'água, Trachemys dorbigni, foram monitorados durante a estação reprodutiva de 2005/2006 para avaliar as taxas de predação e a variação temporal destas; identificar as espécies predadoras, sua importância na destruição dos ninhos e determinar a influência da dispersão dos ninhos sobre a predação, no extremo sul do Brasil. Dos 58 ninhos monitorados, 98% (n = 57) foram destruídos por predadores. Eventos de predação ocorreram predominantemente nas primeiras 48 horas após a oviposição e não houve variação temporal nas taxas de predação. Através de armadilhas fotográficas e observações diretas foram identificadas seis espécies predadoras dos ninhos, não havendo prevalência de nenhuma das espécies. A densidade de ninhos não influenciou as taxas de predação, mas houve correlação negativa entre densidade e tempo decorrido entre a desova e a predação.<br>Nests of the D'Orbigny's slider, Trachemys dorbigni, were monitored during the nesting season of 2005/2006 to evaluate predation rates; time variation on these rates; to identify predator species and their importance on nest destruction and the influence of nest dispersion on predation rates in Southern Brazil. Of the 58 monitored nests, 98% (n = 57) were destroyed by predators. Predation events occurred primarily during the first 48 hours after oviposition and there was no time variation on predation rates. Using camera traps and direct observations we could identify six species of nest predators. There was not prevalence of any predator. Nest density did not influence predation rates, but there was a negative correlation between time after egg laying and predation
