Habitat Selection and Seed Dispersal by the Great Blue Turaco (Corythaeola cristata) in the Rainforests of Southern Cameroon

Biotropica, Volume 58, Issue 1, January 2026.
This study is the first to use telemetry to document the movements of the great blue turaco, a bird that plays an important role in seed dispersal throughout Africa's Congo Basin. We show how 3D vegetation structure influences the movements of four turacos and the resulting spatial patterns of seed dispersal.

The Shyest Blackfish: The Global Phylogeography of the Pygmy Killer Whale (Feresa attenuata) Suggests Considerable Population Structure and an Unrecognized Taxon

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Pygmy killer whales (Feresa attenuata) are a poorly studied, globally‐distributed species found in pelagic waters and around oceanic islands. They are naturally rare, making them difficult to study. Reports indicate that they are highly vulnerable to artisanal fisheries bycatch in some areas.

Mapping the density of giant trees in the Amazon

New Phytologist, Volume 249, Issue 1, Page 152-168, January 2026.
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

Non‐Native Plants Alter Bird‐Plant Frugivory Network Structure in a Human‐Modified Tropical Landscape

Ecology and Evolution, Volume 15, Issue 12, December 2025.
DNA metabarcoding of faecal samples from 21 frugivorous bird species in Gamboa, Panama, was used to assess how non‐native plants influence frugivory network structure. Non‐native species, though comprising only 28% of plants, reduced nestedness, increased connectance and modularity, and caused disproportionately high secondary bird extinctions while ...
