Última A preliminary analysis of death cause, capture-related mortality, and survival of adult red deer in northwestern Patagonia Ecología austral Flueck,Werner T; Smith-Flueck,Joanne M; Bonino,Never A. The red deer (Cervus elaphus), among the world´s 14 most invasive exotic mammals, has recently arrived in Patagonia. Forty-seven deer were captured, marked with radio collars, and monitored in order to determine survival rates and identify causes of death. Net gunning from a helicopter allowed captures to be evenly distributed through the study area and in a timely manner. The absence of capture related mortality in our study agrees with previously reported low rates for this method. Animals were monitored for periods ranging from 5 to 2611 days. Ten animals provided censored values due to radio failures or being shot: they survived on average 811 days (SE = 221) after capture. Ten animals experienced natural deaths with an average time alive after capture...

Red deer (Cervus elaphus) were introduced to Patagonia in the 1920´s and have reached high densities in certain areas of the forest-steppe ecotone. Severe drought conditions during summer/autumn of 1999 were suspected to have an impact on reproduction of red deer. Necropsies of 50 adult females revealed a pregnancy rate of only 56% as compared to 98% in 1992-1998 or 100% in 1996-1997 in other population. The age distribution of pregnant females reflected the importance of not having been pregnant during the previous cycle. The primiparous 2 year-old females had a 77% pregnancy rate, whereas none of the lactating females were pregnant. Normally, a higher reproductive success occurs for middle age classes, thereby reducing the chances of becoming pregnant...
