Influence of Fluvial Structure on Benthic Macroinvertebrates in a Restored Meandering River, Geul Basin, Netherlands

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Benthic macroinvertebrates are indicators of water quality and riparian ecosystem health. Their abundance and distribution in streams are associated with river basin environmental factors, including stream biotic and abiotic fluvial processes. We examined benthic macroinvertebrate diversity and abundance in relation to large wood (LW) and pool‐

Aggregating three sources of long‐term trends of swallows and martins to identify priority conservation areas in the Great Lakes region

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our data integration methodology allows managers to identify regions that accumulate evidence of concerning trends across multiple wildlife monitoring schemes. These regions can thus be prioritized in conservation and management efforts. This approach can be generalized to other sources of long‐term monitoring data of different species, at different ...

Strong Variation in Land‐Use Change Impacts on Tropical Avian Phylogenetic Diversity Between Ecoregions Highlights the Need to Sample Large Spatial Scales

Global Change Biology, Volume 32, Issue 1, January 2026.
Forest conversion for agriculture is a major cause of biodiversity loss in the tropics, but its impacts depend on how broadly they are measured. Using data from across Colombia, one of the most biodiverse countries in the world, we examined how deforestation for cattle farming affects the evolutionary history of bird species.

Linking Habitat Conditions, Human Pressures, and Waterbird Diversity in a West African Coastal Wetland

African Journal of Ecology, Volume 63, Issue 8, December 2025.
ABSTRACT The Tanji wetland complex, situated on the Atlantic coast of The Gambia, is a coastal mosaic of mangroves, riparian forest, lagoons, and offshore islands of high ornithological significance. Despite its protected status, the reserve faces mounting pressures from human activities and environmental change, yet comprehensive ecological data ...

Signal Traits and Oxidative Stress: A Comparative Study Across Populations with Divergent Signals

Frontiers in Ecology and Evolution, 2016
Diverging populations often shift patterns of signal use – a process that can contribute to reproductive isolation and speciation. Yet it is not clear why most traits gain or lose signal value during divergence.

Recombination Rate and Recurrent Linked Selection Shape Correlated Genomic Landscapes Across a Continuum of Divergence in Swallows

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Disentangling the drivers of genomic divergence during speciation is essential to our broader understanding of the generation of biological diversity. Genetic changes accumulate at variable rates across the genome as populations diverge, leading to heterogenous landscapes of genetic differentiation.

Taxonomic resolution in dual‐polarization weather radar observations of biological scatterers: A systematic review

Ecosphere, Volume 16, Issue 10, October 2025.
Abstract The derivation of biological information—abundance, diversity, movement of organisms—from dual‐polarization weather surveillance radars (WSRs) presents an opportunity for novel large‐scale biodiversity monitoring. This review takes a systematic approach to ask what degree of taxonomic resolution has so far been achieved in dual‐polarization ...

The Relationships of the Swallows (Hirundinidae)

Journal of the Yamashina Institute for Ornithology, 1982
The single-copy DNA sequences of the Bank Swallow (R. riparia) and the Barn Swallow (Hirundo rustica) were radio-labeled and compared with the DNAs of an array of other oscine species, using the technique of DNA-DNA hybridization. The results indicate that the swallows shared a most recent common ancestor with the sylviine-timaliine cluster, and that ...

Functional and Phylogenetic Structure of Forest Bird Assemblages Along an Afrotropical Elevational Gradient

Ecology and Evolution, Volume 15, Issue 9, September 2025.
On Mt. Cameroon, functional richness and taxonomic diversity decreased with elevation, while functional nearest neighbor distance, functional evenness, and mean nearest taxon distance showed positive trends. Traits related to resource use indicated that higher‐elevation species were functionally less similar than expected by chance, supporting ...
