Proximity to Natural Habitat Is Not Consistently Associated With Pollination Services in Tropical Smallholder Farms: A Systematic Review and Meta‐Analysis

Ecology Letters, Volume 28, Issue 12, December 2025.
We conducted a systematic review and meta‐analysis of 35 studies to examine the relationship between distance to natural habitat and pollinator abundance, species richness and crop fruit set in tropical smallholder farms. We found no consistent effects on abundance or fruit set, and only a slight, highly variable negative effect on pollinator richness,

Feather Microbiota Landscapes: Biogeography and Phenology Shape Feather Microbiota Traits in a Migratory Seabird in a Subantarctic Ecosystem

Molecular Ecology, Volume 34, Issue 21, November 2025.
ABSTRACT It is known that phenological changes (i.e., behavioural and sometimes morphological and physiological traits that repeat annually) influence the wildlife gut microbiota. However, it remains largely unknown to what extent geographic variation could modulate the effect that phenology has on wildlife microbiota.
