Unexpected diversity of alternative reproductive tactics revealed in Water Rails (Rallus aquaticus)
Ibis, Volume 168, Issue 1, Page 216-229, January 2026.Monogamy in birds was long considered a general mating system until molecular studies provided evidence of alternative reproductive strategies (ARS), which are now assumed to be present in ~90% of bird species. These ARS or tactics (ART), as we consider them in this study, include extra‐pair copulation, which can lead to extra‐pair paternity or extra ...

The dual role of red deer in yellow rockrose seed dispersal and predation in Mediterranean Spain
Plant Biology, Volume 27, Issue 7, Page 1468-1477, December 2025.Red deer play a mostly antagonistic and predatory role on Cistus halimifolius seeds, but here, it has been demonstrated, for the first time, their overlooked mutualistic potential role as long distance disperser. Abstract Endozoochory, seed dispersal after animal ingestion, is a mutualistic plant–animal interaction that often involves substantial costs

Ecological Monographs, Volume 95, Issue 4, November 2025.Abstract Climate change is altering the phenology of interacting species, potentially leading to mismatches in the timing of their interactions. This may affect the delivery of key ecosystem services such as pollination. Temperature‐mediated phenological variation has been widely studied at the species level, showing that increased temperatures lead to
