Niche Segregation Between Black‐Necked Crane and Common Crane in Human‐Modified Landscape, Huize Black‐Necked Crane National Nature Reserve, Yunnan Province, Southwestern China

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We investigated how Black‐necked Cranes and Common Cranes coexist in agro‐wetland landscapes of southwest China by reconstructing their plant‐based diets using eDNA metabarcoding. Black‐necked Cranes maintained broad, stable diets centered on natural vegetation, while Common Cranes shifted dynamically to energy‐dense crops, leading to progressive niche

Cryptic Diversity and Genetic Variation in a Korean Endemic Freshwater Fish, the Korean Dark Chub (Zacco koreanus) Compared With Its Relative Zacco temminckii

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
The phylogenetic relationship analyses revealed four distinct lineages within Zacco koreanus, with the Nakdong and Seomjin River populations showing approximately 2.6% genetic divergence from other lineages—comparable to the interspecific distance between Z. koreanus and Z. temminckii (~2.7%).

Mating Patterns and Postzygotic Barriers in a Hybrid Swarm of Two Closely Related Pigeon Species

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Based on the observed mating structure and reproductive outcomes, hybrid index values of the resulting offspring shifted toward the feral pigeon end. This pattern indicates ongoing introgression of feral‐derived alleles into the hybrid population. ABSTRACT Hybrid zones provide a valuable framework for understanding evolutionary pathways.

New Insights Into the Biogeography of Six Garra Species (Teleostei: Cyprinidae) in the Persian Gulf Basin

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We present data and inferences supporting the case for post‐LGM secondary contact between eastern and western G. rufa populations that became isolated by post‐Pleistocene sea level rise of the Persian Gulf. We suggest river capture as a probable mechanism explaining secondary dispersal of Garra rufa populations from eastern to western river drainages ...

High Contrast Markings Can Negate the Benefits of Transparent Camouflage

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Transparency is perhaps theoretically the most efficient means of achieving camouflage; however, in application, species show considerable variance in their degree of transparency. We demonstrate the fragility of transparent camouflage, detailing how imperfections reduce efficacy with implications in predation risk. ABSTRACT Transparency is, in theory,
