Successful stocking of wild European perch in a reestablished lake with lasting effect over 10 years

Restoration Ecology, Volume 34, Issue 1, January 2026.
Biological manipulation of fish compositions to enhance top‐down control of trophic webs is a common method for improving water and ecological quality in shallow eutrophic lakes, but it often fails. As an alternative to manually thinning unfavored fish stocks, piscivorous fish species can be released to suppress the recruitment of cyprinid fish ...

Protective Role of Egg Yolks From Different Avian Species on the Post‐Thaw Quality and Fertility of Cryopreserved Nile tilapia (Oreochromis niloticus) Sperm

Aquaculture Research, Volume 2026, Issue 1, 2026.
Egg yolks derived from various avian species have been widely applied as cryoprotective additives in mammalian sperm preservation; however, their efficacy in fish sperm cryopreservation remains poorly understood. Therefore, this study evaluated the cryoprotective effects of quail (Coturnix coturnix), chicken (Gallus gallus domesticus), and turkey ...

Spatial Patterns of Diversity in Forest Birds of Peninsular India

Ecology and Evolution, Volume 15, Issue 12, December 2025.
In this study, we analyzed patterns of diversity and endemism of forest birds across peninsular India, highlighting the influence of climate and topography. Our study shows that the southern Western Ghats are a major evolutionary hotspot for forest birds in peninsular India, and topographically complex and climatically stable areas support the highest ...
