Genetic Diversity, Population Structure, and Environmental Influences in Nepeta glomerulosa: Implications for Conservation in the Irano‐Turanian Region

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Nepeta glomerulosa shows moderate genetic diversity with three main clusters and significant admixture, highest in the Alborz Mountains, suggesting it may be the center of origin. High genetic differentiation (Gst = 0.4199) points to limited gene flow and possible self‐pollination, with geographic isolation shaping population structure.

Spatial Distribution, Abundance, and Threats to the Indian Pangolin (Manis crassicaudata) in Buner District, Lesser Himalayas

Ecology and Evolution, Volume 16, Issue 5, May 2026.
First quantitative study of the Indian pangolin population in Buner District. GIS mapping revealed uneven spatial distribution across elevation zones. ABSTRACT The Indian pangolin (Manis crassicaudata), an elusive and endangered mammal, remains poorly studied in Pakistan, particularly in the mountain landscapes of the Lesser Himalayas.

Genomic and Mitonuclear Patterns of Divergence Among Recently Diverged White‐Crowned Sparrow Subspecies

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The study investigates genetic divergence among white‐crowned sparrow subspecies across North America, revealing three to four distinct genetic clusters based on genome‐wide SNP analysis, particularly highlighting divergence in the Z chromosome. Notably, Z. l. pugetensis consistently diverges from other populations, and a north–south split within Z. l.

Nutrient enrichment strengthens feedbacks that promote and stabilize coral‐to‐macroalgae regime shifts on tropical reefs

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Ecosystems around the world have experienced shifts in community state as a result of anthropogenic activities that alter important ecological feedbacks. On coral reefs, transitions to a state where fleshy macroalgae are a major space holder have often been associated with the loss of top‐down control, which frequently has been attributed to ...

Plant species richness response to atmospheric nitrogen deposition across bedrock types in the United States and Czechia

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Atmospheric nitrogen (N) deposition leads to many changes in terrestrial and aquatic ecosystems, affecting ecosystem processes and species composition. Terrestrial vegetation often shifts from being N‐limited to light‐limited and becomes dominated by a few fast‐growing strong competitors and generalist species.
