The ability of climate envelope models to predict the effect of climate change on species distributions por Hijmans, Robert J., Graham, Catherine H.

“…Our results suggest that some CEMs can indeed be used to predict species distributions under climate change, but individual modeling approaches should be validated for this purpose, and model choice could be made dependent on the purpose of a particular study.…”

‘Gold runs through these trees’: Preferences for ecosystems payment programs in Papua New Guinea por Mukerjee, Rishabh, Schmidt, Emily, Holtemeyer, Brian

“…Using recently collected rural household survey data, we evaluate the unique characteristics that are correlated with forest-owning households’ likelihood of accepting a PES contract. The discrete choice experiments included in the survey, and complementary focus group discussions suggest that forest landholders prefer PES contracts with higher financial incentives and lower land area commitments, requiring an additional $39.07 per hectare per year to preserve all forested land compared to committing half of their forested land to a PES contract. …”

Physiological basis for yield differences in maize (Zea mays L.) under varying nitrogen rates and planting windows in the savannas of Nigeria por Ahmad, N.M.

“…The results indicated that the most favorable sowing window identified for planting of maize is the mid-June to late June for Sudan Savanna and mid-June to early July for Northern Guinea Savanna. Furthermore, the choice of maize variety emerges as a critical factor influencing yield, irrespective of location. …”

Gender roles in ruminant disease management in Uganda: Implications for the control of peste des petits ruminants and Rift Valley fever por Namatovu, Jane, Lule, Peter, Asindu, Marsy, Campbell, Zoë A., Tumusiime, Dan, Kiara, Henry K., Bett, Bernard K., Roesel, Kristina, Ouma, Emily A.

“…This qualitative study asks what men and women do to prevent or control diseases that affect them and their livestock and what factors influence the choice of disease control measures taken. Discussants represented three production systems (pastoral, agro-pastoral, and mixed crop livestock), selected for the high prevalence of two livestock diseases (peste des petits ruminants and Rift Valley fever). …”
