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

Biotropica, 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.

Sustainable control of Dalbulus maidis: A field study with entomopathogenic fungi

Entomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1156-1164, November 2025.
Dalbulus maidis, a plant pathogen vector, poses a serious threat to maize production and food security. We investigated the potential synergistic effects between formulations based on entomopathogenic fungi and corn hybrids with varying resistance to maize stunt complex and Maize rayado fino virus. The combined management of M. anisopliae + B. bassiana

Seasonal and intracanopy shifts in the fates of absorbed photons in central Amazonian forests: implications for leaf fluorescence and photosynthesis

New Phytologist, Volume 248, Issue 1, Page 76-91, October 2025.
Summary Recent studies have shown a linear relationship between solar‐induced Chl fluorescence (SIF) and gross primary productivity (GPP) at large scales. However, this relationship diverges at finer leaf scales, particularly in tropical forests with complex canopy structures.

Foliar herbivory pushes plant individuals towards the periphery of a plant–floral visitor interaction network

Journal of Ecology, Volume 113, Issue 9, Page 2414-2428, September 2025.
The authors demonstrate how the effects of herbivory on a key plant trait can cascade to shape the interactions between individual plants and their flower visitors and how the indirect effects between herbivores and pollinators can modulate the structure of interaction networks in terrestrial ecosystems.

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati)

Medical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.
Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...
