A Conservation Assessment and Systematic Review of the Endangered Spectacled Flying‐Fox 濒危眼镜狐蝠的保护评估与系统综述

open access: yesWildlife Letters, Volume 3, Issue 4, Page 173-193, December 2025.
Spectacled flying‐fox Pteropus conspicillatus populations have declined so seriously over two decades that they are now endangered. Inaction has allowed threats to increase. Extreme heat events are now a lethal reality, habitat loss continues almost unabated, and pressure to disperse roosts is ever‐present. Obtaining resources and taking action to help

Manipulation of photoperiod in growth factors of beluga sturgeon Huso huso [PDF]

open access: yesAfrican Journal of Biotechnology, 2010
The beluga sturgeon is considered as the most important species for caviar production. This study aimed to evaluate effects of photoperiod manipulation on growth factors of beluga sturgeon. The six photoperiod regimes (light: dark cycle) including natural photoperiod (control), 24L : 0D, 16L : 8D, 12L : 12D, 8L : 16D and 0L : 24D with the three ...

The effects of stocking density on the production and health of olive flounder (Paralichthys olivaceus) in RAS

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 6, December 2025.
Abstract Olive flounder (Paralichthys olivaceus) is known for its growth performance in aquaculture. Fish are typically raised at high densities in recirculating aquaculture systems (RAS), which may impact animal health. Flounder (55.2 ± 16.3 g) were stocked at three densities: a low density (LD) of 3 kg/m2, medium density (MD) of 6 kg/m2, and high ...

Herbivory Modifies the Role of Spatial Processes in a Grassland Plant Metacommunity

open access: yesEcology Letters, Volume 28, Issue 11, November 2025.
We empirically examined how mammalian herbivory interacts with habitat size and connectivity to affect plant diversity in a natural grassland metacommunity. We found that herbivory increased plant diversity across scales of measurement and reversed the diversity–area relationship, showing a positive relationship in grazed and a negative relationship in

Research on the Application of Green Ecological Additive Combinations During the Breeding Period of Redclaw Crayfish

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT The three key processes in the breeding of redclaw crayfish are nutrient enhancement by parents, catching and hatching of egg‐holding crayfish and maintaining a feed supply for juveniles. An appropriate combination of green ecological additives is beneficial for improving the production efficiencies of the three key processes.
