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

Land 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.

Associating Local‐Scale Physical Habitat Assemblages With Reach‐Scale Stream Hydrogeomorphological Types in Mountain Headwater Catchments

River Research and Applications, EarlyView.
ABSTRACT Building an understanding of river ecosystems often involves integrating information from different locations, spatial scales and points in time. Geomorphologists and ecologists have long considered ways to explore river ecosystems at different, hierarchical, spatial scales so that features observed locally can be linked to the character of ...
