Forest edges buffer effects of agricultural management on bee–plant interaction networks

Ecological Entomology, EarlyView.
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

Wood Thrush (Hylocichla mustelina) occupancy patterns reveal sensitivity to low precipitation on nonbreeding grounds in northern Costa Rica

Ibis, EarlyView.
Climatic change and anthropogenic disturbances are reshaping animal populations. Habitat loss and extreme climatic events are particularly strong drivers of declines in species that depend on forested areas. For migratory songbirds, climate and the persistence of suitable habitat over time are fundamental to sustaining populations annually.

Between Autonomy and Dependency: The Territorialisation of Agroecology in the Colombian Peasant Reserve Zones

Journal of Agrarian Change, EarlyView.
ABSTRACT Peasant movements employ a spectrum of politico‐economic strategies for territorialising agroecology, ranging from autonomy to (inter)dependency. To substantiate this argument, I draw on qualitative fieldwork and historical analysis to examine the Colombian Peasant Reserve Zone movement's strategies for territorialising agroecology at both the

Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

Journal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.

Tick‐borne diseases in subtropical dairy farming: The role of calf rearing strategies in antibody and antigen prevalence Enfermedades Transmitidas por Garrapatas en la Ganadería Lechera subtropical: El Papel de las Estrategias de Crianza de Terneros en la Prevalencia de Anticuerpos y Antígenos

Medical and Veterinary Entomology, EarlyView.
Tropical farmers try to adapt calf‐rearing systems to temperate dairy industry standards. Calves in tick‐infested areas develop stronger immunity to TBD under controlled exposure to ticks. Early tick exposure promotes sustainable management, balancing tick infestation and developing TBD immunity.
