TL;DR: The elastic net, lasso, adaptive lasso and the adaptive elastic net all had similar accuracies but outperformed ridge regression and ridge regression BLUP in terms of the Pearson correlation between predicted GEBVs and the true genomic value as well as the root mean squared error.

TL;DR: In this paper, the authors analyzed the population dynamics of northern ungulates in South Africa's Kruger National Park over a period from 1977 to 1996 and found that the population decline of seven species was not explained by indices of ENSO or its effects on annual rainfall, but rather by an extreme reduction in dry season rainfall concurrent with and perhaps related to a regional temperature rise.

TL;DR: This work relates African lion population densities and population trends to contrasting management practices across 42 sites in 11 countries to show that lions in unfenced reserves are highly sensitive to human population density in surrounding communities, and unfenced populations are frequently subjected to density-independent factors.

TL;DR: Policy, institutional and management interventions likely to succeed in reducing the declines and restoring rangeland health, most notably through strengthening and investing in community and private wildlife conservancies in the rangelands are suggested.

TL;DR: It is found that wildlife populations in the Mara region declined progressively after 1977, with few exceptions, and human influences appeared to be the fundamental cause.
