Persistent Genomic Erosion in Whooping Cranes Despite Demographic Recovery

Molecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Integrating in‐situ (wild) and ex‐situ (captive) conservation efforts can mitigate genetic diversity loss and help prevent extinction of endangered wild populations. The whooping crane (Grus americana) experienced severe population declines in the 18th century, culminating in a collapse to ~20 individuals by 1944.

Effects of breeding success, age and sex on breeding dispersal of a reintroduced population of the Crested Ibis (Nipponia nippon) in Ningshan County, China

Avian Research, 2018
Background Breeding dispersal is an important ecological process that affects species’ population dynamics and colonization of new suitable areas. Knowledge of the causes and consequences of breeding dispersal is fundamental to our understanding of avian

Mosquito iDNA Reflects Fine Scale Composition of Tropical Fauna

Environmental DNA, Volume 7, Issue 6, November–December 2025.
We used mosquito iDNA to investigate fine scale ecological patterns of birds and mammals in the tropical savanna woodlands of Kakadu National Park. Revealing that mammalian richness is influenced by site, while avian richness changes with season. While community composition is influenced by fire during the dry season and vegetation during the wet ...

Compounding Impacts of Extreme Climate Events on European Birds Under Climate Change

Conservation Letters, Volume 18, Issue 6, November/December 2025.
ABSTRACT When multiple simultaneous or successive extreme climatic events occur, compound impacts can follow, where the effects of one event worsen the impacts of another. Surprisingly, the risks that these compound events pose to biodiversity have rarely been investigated.

ZW and XY Sex Chromosomes Drive Rapid and Distinctive Evolution of Sex‐Biased Gene Expression

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Cichlids are a textbook model system of adaptive radiation and a fascinating example of rapid sex chromosome evolution. Yet in these fish, as in most other taxa, the mechanisms causing sex chromosome turnover and the subsequent impact thereof are unknown.

Monitoring faunal responses to biodegradable oyster reef restoration materials with camera traps in a subtropical estuary

Restoration Ecology, Volume 33, Issue 8, November 2025.
Oyster reef restoration has become increasingly crucial due to global population declines. Intertidal oyster reefs provide essential foraging and loafing (resting) grounds to estuarine fauna. To reduce plastic pollution from traditional materials, biodegradable restoration materials have been introduced and are shown to support oyster recruitment ...

Assessing Habitat Suitability and Connectivity of Black Storks in China: Integrating Species Distribution Models and Landscape Connectivity Analysis

Ecology and Evolution, Volume 15, Issue 10, October 2025.
The black stork, a vital wetland species, is threatened by habitat fragmentation, with this study using the MaxEnt model to identify key habitats in North China, Xinjiang, and the Yangtze River Basin. An ecological corridor network of 28,312 km connects these regions, highlighting four critical nodes for prioritized conservation to enhance habitat ...
