Through the eyes of the Andean bear: Camera collar insights into the life of a threatened South American Ursid

Ecology and Evolution, Volume 14, Issue 12, December 2024.
This study used a camera‐equipped GPS collar on a male Andean bear in southeastern Peru, revealing rare behaviors like courtship, novel diets, and geophagy. These findings from the Kosñipata Valley provide valuable insights into the poorly understood ecology of Andean bears and suggest many areas for further research.

Photosystem rearrangements, photosynthetic efficiency, and plant growth in far red‐enriched light

The Plant Journal, Volume 120, Issue 6, Page 2536-2552, December 2024.
SUMMARY Arabidopsis plants were grown in white light (400–700 nm) or in white light supplemented with far‐red (FR) light peaking at 730 nm. FR‐enriched light induced the typical shade avoidance syndrome characterized by enhanced length of seedling hypocotyl and leaf petiole.

Elevational and Seasonal Patterns of Plant–Hummingbird Interactions in a High Tropical Mountain

Ecology and Evolution, Volume 14, Issue 10, October 2024.
This study examined the patterns and potential drivers of diversity and spatiotemporal dynamics of plant–hummingbird interactions across Mexico's high tropical elevational gradient. Results revealed the importance of species turnover, interaction rewiring, and phenological overlap in network structuring, with smaller roles of abundance, morphology, and

The role of bromeliad structural complexity on the presence, spatial distribution and predator avoidance in Tityus neglectus (Scorpiones: Buthidae)

Ecology and Evolution, Volume 14, Issue 6, June 2024.
Due to remarkable architectural design featuring rosette‐like leaf arrangements, bromeliads serve as habitats for various species. Bromeliad architecture is a key factor in the spatial distribution and occurrence of the Tityus neglectus scorpion. Furthermore, T.
