What about survivorship to maturity?158 Evolutionary Anthropology ARTICLE this is very odd, and they don't evfen attempt to explain it -they also don't mention the growth spurt... They don't really define the juvenile phase or present data, though this is one of their most important variables...

Over 1,400,000 m of line transect data were collected in collaboration with Ache Indians to determine encounter rates with all large vertebrates in the Mbaracayu Reserve Paraguay. The data were analyzed using logistic regression in order to determine the impact of human hunting on animal encounter rates in the reserve. The method controlled for effects of season, weather, time of day, and habitat in order to statistically isolate the human predation effect. Encounters with the animals themselves as well as fresh signs of their activity allowed us to determine whether lower encounter rates in hunted zones are simply due to increased wariness by target species. Our results show that areas near hunters are hunted more frequently, and that Dasypus novemcinctus, Cebus apella, Tapirus terrestris, and Mazama spp. are all encountered at lower rates in those areas than in unhunted zones. We were unable to show that encounter rates with other important game species have been affected by human hunting. Demonstration of local depletion by central place foragers is expected, however, and cannot be used to conclude that prey species are in danger of regional extirpation.

Race is often identified as uniquely defining and influencing electoral processes in the United States. However, little empirical research has investigated the consequences of racial diversity for levels of voter turnout or for the nature of mobilizing institutions. On the basis of historical analyses of U.S. politics, we hypothesize that greater racial diversity is associated with lower levels of voter mobilization, weaker mobilizing institutions, and higher barriers to voter participation. Cross-sectional models for the 1950s, the 1980s, and the 1990s are tested with ordinary least squares regression techniques, using states as the unit of analysis. We find that racial diversity is a potent negative predictor of turnout levels, in each time period and in non-Southern, as well as Southern, states and that it has an especially strong relationship in presidential elections. Racial diversity is also associated nationwide with weak state and national mobilizing forces, and more difficult voter registration requirements.
