Caste‐Associated Social Context Modulates Behavioural Interactions With Insecticide‐Exposed Individuals in Nasutitermes corniger (Termitidae: Nasutitermitinae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Termites are eusocial insects that maintain cohesion and exchange information through frequent physical interactions among nestmates. This social organisation underlies the principle of horizontal insecticide transfer, which is widely exploited as a termite control strategy.

Widespread forest-savanna coexistence but limited bistability at a landscape scale in Central Africa

Environmental Research Letters
Tropical 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.

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

Journal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...

Bringing Fire Back: How Prescribed Fires Shape Ant Communities in a Fire-Suppressed Neotropical Savanna

Diversity
We 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.

Conservation Management Strategies Shape Glucocorticoid Levels in African Elephant Populations More Than Parasite Load

Journal of Zoology, EarlyView.
Understanding the factors influencing physiological stress is essential for interpreting how wildlife responds to contrasting environmental and management conditions. Across 19 South African elephant populations, we found that smaller reserves, self‐drive tourism, and high elephant density under low vegetation productivity were associated with elevated

How Institutions Shape the Effects of Agricultural Cooperatives on Their Members

Kyklos, EarlyView.
ABSTRACT Agricultural cooperatives represent a promising way of improving the quality of life of half a billion smallholders, who account for the vast majority of the world's food production. Yet, little is known about the institutional factors that explain the potential benefits of being a member of a cooperative.

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

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

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.

Large underestimation of smallholder agriculture in the tropics by classic remote sensing products: evidenced from the Kasaï River Basin

Environmental Research Communications
The Kasaï River Basin (KRB), the largest tributary system of the Congo basin, is undergoing rapid land-use transformation driven by population growth and expanding economic activities.
