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.

Data gaps and heterogeneity limit our understanding of human–wildlife interactions: A continental study of Andean bears

People and Nature, Volume 8, Issue 5, Page 1499-1519, May 2026.
Abstract The expansion and intensification of human activities have increased interactions between people and wildlife. Interactions involving bears and other large carnivores are complex and can lead to conflicts. Promoting positive coexistence requires managing information, which is not always available.

Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

Journal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

Depositional and stratigraphic evolution of a Permian megalake system: Implications for seiche‐influenced models

The Depositional Record, Volume 12, Issue 2, April 2026.
During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

TAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Designing networks of freshwater and marine conservation areas accounting for cross‐realm connectivity and threat propagation

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
This study highlights the importance of integrating cross‐realm connectivity and threat propagation when designing new or expanding existing networks of conservation areas, such as the Natura 2000 European network of protected areas. These findings emphasize the need for multirealm planning that supports species persistence, protects transitional ...
