Journal of Anatomy, EarlyView.Graviportal proboscideans differ in limb morphology, adopting slender or more robust long bone morphotypes. Finite element analyses (FEA) on extant and extinct taxa reveal functional differences between morphotypes, with robust humeri exhibiting lower peak stress under neutral and off‐axis loading.

Widespread forest-savanna coexistence but limited bistability at a landscape scale in Central Africa
Environmental Research LettersTropical forest and savanna frequently coexist under the same climatic conditions, which has led to the hypothesis that they could represent alternative ecosystem states, stabilized by internal feedbacks.

Occurrence and distribution of sarcoptic mange in wild Neotropical canids
Medical and Veterinary Entomology, EarlyView.Sarcoptic mange affects most Neotropical canid species across multiple countries. It represents a widespread yet largely overlooked conservation threat with potential for cross‐species transmission. Coordinated monitoring and management efforts are needed to understand and mitigate its impacts. Abstract Sarcoptic mange, a contagious skin disease caused

DiversityWe evaluated the effects of different fire regimes on the ground-ant community from a savanna (Cerrado) reserve in southern Brazil, where a process of woody encroachment has been taking place. Ants are a dominant faunal group in tropical savannas.

New Phytologist, EarlyView.Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

Plant Breeding, EarlyView.ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Plant Breeding, EarlyView.ABSTRACT Sorghum [Sorghum bicolor (L.) Moench] is a vital cereal crop in dry regions worldwide. However, in sub‐Saharan Africa (SSA), grain yields from currently grown varieties remain low (< 1 ton/ha) and exhibit variable nutrient composition. Therefore, the objective of this study was to undertake a genetic analysis of selected East African‐adapted ...

Plant Biology, EarlyView.For most traits, floral intra‐individual variation was similar between morphs and populations with different pollinator guilds (bees and hummingbirds), potentially facilitating effective pollen transfer in distylous systems. Still, greater variation in corolla length increased pollen deposition in L‐morph flowers in the bee‐pollinated population ...
