The disappearance of many North American megafauna at the end of the Pleistocene is a contentious topic. While the proposed causes for megafaunal extinction are varied, most researchers fall into three broad camps emphasizing human overhunting, climate c

As in the case above, non-parametric (quantile) regressions with spatial weights separately from Q and W matrices were run to estimate Eq. 1 at four percentiles of the dependent variable assuming (i) deviation from normality, (ii) non-linear dependence between predictors and the dependent ...
had China maintained the 1994 poverty rate of 57.8% in the period 1994 to 2020, there would be 820 million more people globally living in poverty in 2020, and the global poverty rate in 2020 would have been 19.4%—equivalent to the level in 2007—rather than the actual estimate of 8.9%...
home range estimate for males is significantly greater than females40supporting our hypothesis that females are indeed subjected to site fidelity. Unfortunately, confirming the sex of most individuals, even in Quito and Zamora where we matched the collected samples to camera trap data, proved challengi...

It was not possible for experts to estimate the impact of different human land uses on the abundance of every terrestrial vertebrate and vascular plant species in sub-Saharan Africa (±50,000 species), both because of the large number of estimates that would be required, and because there are...
Different clock rates were used for the control region and the remainder of the mitochondrial genome, 5.0e−8 per site per year (site−1/year−1), and 3.28e−9 site−1/year−1, respectively (Bowen et al. 2006; Gillooly et al. 2005). The latter estimate was based on the ...
