Pollen essential amino acids shape bat–flower interaction networks

open access: yesFunctional Ecology, Volume 39, Issue 11, Page 3311-3324, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Although pollen consumption by phytophagous bats has long been documented, the role of its protein and amino acid content in driving plant–pollinator interactions remains largely overlooked.

When Raptors Are Away, Opossums Will Play: Woolly Opossums as Carrion Feeders in Harpy Eagle Nests

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
Scavenging by New World marsupials is rarely documented. We recorded woolly opossums (Caluromys lanatus) scavenging prey remains from a Harpy eagle’s nest in central Brazil. The low overlap in activity periods between the two species may facilitate the behavior observed here.

Oxygen Isotopes as a Key Proxy of Equatorial Pacific SST Variability in a Multiparametric Tree‐Ring Approach in the Low‐Latitude Andes

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 9, September 2025.
Abstract Sea surface temperature (SST) variability in the equatorial Pacific plays a crucial role in shaping global climate patterns. As El Niño–Southern Oscillation (ENSO)‐related extremes intensify, understanding SST fluctuations and their connection to ENSO becomes increasingly important.
