Movement Strategies of Neotropical Nectarivorous Birds: Insights From High‐Andean Hummingbirds and Flowerpiercers

Biotropica, Volume 58, Issue 1, January 2026.
Nectar is a highly variable, mostly unpredictable resource in tropical mountains. How do nectarivorous birds such as this male Great Sapphirewing cope? Fine‐scaled tracking of hummingbirds and flowerpiercers shows flexibility in daily movement strategies in the high Andes, possibly in response to fluctuating local conditions such as weather and ...

Racing Amidst Change: Urbanization and Climate Alter Functional Traits and Distribution of an Amazonian Parthenogenetic Lizard

Biotropica, Volume 57, Issue 5, September 2025.
By comparing native and neonative populations of an Amazonian lizard, we examine how urban environments and climate change impact its functional traits, while also predicting its future distribution. Our findings offer insights into how some species may adapt to human‐altered landscapes, showing that not all are negatively affected by these changes ...

Foxes as pets: Case study of the Fuegian Dog and its relationship to extinct Indigenous cultures

Journal of Zoology, Volume 327, Issue 1, Page 5-18, September 2025.
This is a rare glimpse into the historical past of the zoologically mysterious Fuegian Dog that lived with early Holocene Indigenous groups on the island of Tierra del Fuego. Records of the animal's appearance and behavior kept by early explorers, artists and scientists who travelled to the tip of South America, plus the genetics and archaeological ...

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Predator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...

Gill evolution in Neotropical electric fishes: Comparative phylogenetic evidence for hypoxia‐driven adaptation

Functional Ecology, Volume 39, Issue 8, Page 1940-1956, August 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Tropical freshwater fishes are often exposed to hypoxia, which limits aerobic metabolism and drives the evolution of diverse physiological, behavioural and morphological adaptations.
