Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, Volume 95, Issue 3, Page 397-417, March 2026.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Record phenological responses to climate change in three sympatric penguin species

Journal of Animal Ecology, Volume 95, Issue 3, Page 455-469, March 2026.
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

Seasonal and Within‐Day Variation on Hummingbirds Visits and Dominance Hierarchy in a Brazilian Cerrado Area

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT Plant‐hummingbird interaction networks can be influenced by environmental conditions and resources, which vary seasonally and daily. We aimed to understand how variations in these parameters across these two temporal windows influence patterns of plant‐hummingbird interactions and hummingbirds dominance hierarchies in a Brazilian Cerrado ...

Estado trófico y estructura comunitaria del microfitoplancton en un sector del golfo de Guayaquil, Ecuador

Biota Colombiana, 2018
El incremento urbano en zonas costeras ha conducido a la eutrofización, cuya acumulación de residuos orgánicos ha afectado también al estuario del golfo de Guayaquil; por ello, se determinó el estado trófico utilizando el índice Karydis, a una milla del

Patch and Landscape Predictors of Mammal Diversity and Their Trait‐Relationships in the Largest Atlantic Forest Island in Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...
