Spatial and temporal variation in survival of female wild turkeys

open access: yesThe Journal of Wildlife Management, EarlyView.
We monitored 370 female wild turkeys across North Carolina's 3 ecoregions from 2020‐2022 to understand factors influencing their survival. Female survival varied by ecoregion and behavior state, with the incubation period having the lowest survival rates. None of the land cover variables affected survival.

Carbon Stock and Environmental Variations of Typical Plantations in Mufu Mountain in Hubei Province, China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forest ecosystems play a critical role in the global carbon cycle. As a significant terrestrial carbon sink, plantations exhibit carbon stock patterns that are shaped by tree species composition, stand structure, and environmental conditions. Here, we investigated typical plantation types in the Mufu Mountain, Hubei Province.
