Inbreeding Depression Manifested in Progeny From Fragmented Populations of the Wind‐Pollinated Dioecious Conifer Afrocarpus gracilior (Pilg.) C. N. Page

Ecology and Evolution, Volume 15, Issue 2, February 2025.
Forest fragmentation in Afrocarpus gracilior reduced genetic diversity and caused significant inbreeding depression, especially in smaller populations. Progeny from these populations showed lower genetic diversity, reduced germination rates, slower growth, and diminished survival. Seeds should be sourced from larger, genetically diverse populations for

UAV‐Based Land Surface Temperatures and Vegetation Indices Explain and Predict Spatial Patterns of Soil Water Isotopes in a Tropical Dry Forest

Water Resources Research, Volume 61, Issue 2, February 2025.
Graphical abstract illustrating the concept of isotopic enrichment of soil water depending on canopy status and plant type. Because of less shading provided, evaporative enrichment in areas without canopy cover is higher compared to areas with intermixed evergreen and leaf‐shedding trees and evergreen patches. E and T are Evaporation and Transpiration,
