Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Information flow and the adoption of soil‐improving and water conservation measures, and household welfare: Insights from a randomized controlled trial in Uganda

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Extension services are designed to facilitate the flow of information from researchers to farmers. However, information failures continue to impede the diffusion of soil‐improving and water conservation technologies in Sub‐Saharan African countries. We use a randomized controlled trial (RCT) to examine the impact of an extension‐based campaign

Use of Cornmeal and Wheat Bran Improves Fermentation Profile and Nutritional Value of Elephant Grass Silage

open access: yesAgriculture
Elephant grass (Pennisetum purpureum Schum.) is a tropical forage with high biomass yield, making it suitable for silage production. However, its low dry matter (DM) at the recommended harvest stage may lead to fermentation problems and increased gas and

Wildebeest movement responses to electric conservation fencing in the African Savannah ecosystem

open access: yesConservation Science and Practice, EarlyView.
These findings provide GPS‐based empirical evidence of how a newly constructed electric conservation fence alters migratory wildebeests, and show that effects are context‐dependent across habitat type, time of day, and distance to the boundary. While such fences can reduce human–wildlife conflict and support conservation goals, they must be carefully ...
