Exploring Andean foothill connectivity: insights from population divergence in the white‐tipped sicklebill, Eutoxeres aquila

Journal of Avian Biology, Volume 2026, Issue 3, May 2026.
The Northern Andes, acting both as barrier and corridor, exert strong influence in Neotropical biodiversity. Still, the diversification of foothill taxa inhabiting ecotonal zones between lowland rainforest and montane environments in this region remains poorly understood.

Plant and soil elemental coupling in response to experimentally altered precipitation and root herbivory in an Australian grassland

Journal of Ecology, Volume 114, Issue 5, May 2026.
This work provides novel experimental evidence on how chemical elements in plants and soils respond to changes in precipitation regimes and shifts in plant–animal interactions (root herbivory), moving the focus from changes in plant and soil elements to the way in which such elements are coordinated.

Nest Predation in the Canarian Houbara Bustard (Chlamydotis undulata fuertaventurae): An Experimental Study Using Artificial Nests

Ecological Research, Volume 41, Issue 3, May 2026.
We investigated nest predation in the endangered Canarian houbara bustard using 229 artificial nests and camera traps. Ravens were identified as the main predators, and predation rates were influenced by raven density, vegetation cover, stone cover, and road density.

Understory frog communities recover quickly during tropical forest regeneration

Ecological Applications, Volume 36, Issue 3, April 2026.
Abstract Millions of hectares of tropical forest have been lost to agriculture, posing a major threat to biodiversity. However, where agricultural activities do not cause irreversible damage, forests can regenerate after abandonment, forming secondary forests that are increasingly important for conserving forest species.

Evidence of Genetic Continuity in the Shortfin Mako Shark (Isurus oxyrinchus) Between the Eastern Atlantic and Mediterranean Sea

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Genomic analyses of shortfin mako sharks from the Eastern Atlantic and Mediterranean Sea reveal a single genetically mixed population, indicating high connectivity across basins. Demographic reconstruction suggests historical stability, though recent declines may be beyond the resolution of our markers. These results underscore the need for coordinated
