Comparative Analysis of Understorey Floristic Diversity and Carbon Stocks in Poorly and Intensively Managed Tectona grandis Plantations

International Journal of Forestry Research, Volume 2020, Issue 1, 2020., 2020
The role of forest plantations in carbon sequestration and biodiversity conservation is a topical issue among researchers and policymakers globally. This study compares understorey floristic diversity and carbon stock of a 15‐year‐old monoculture Tectona grandis plantation under intensive and poor management in a dry semideciduous ecological zone of ...

Height‐related scaling of phloem anatomy and the evolution of sieve element end wall types in woody plants

New Phytologist, Volume 214, Issue 1, Page 245-256, April 2017., 2017
Summary In the sieve elements (SEs) of the phloem, carbohydrates are transported throughout the whole plant from their site of production to sites of consumption or storage. SE structure, especially of the pore‐rich end walls, has a direct effect on translocation efficiency.

Ungulate impacts on herbaceous‐layer plant communities in even‐aged and uneven‐aged managed forests

Ecosphere, Volume 7, Issue 6, June 2016., 2016
Abstract Forest management and ungulate herbivory are extant drivers of herbaceous‐layer community composition and diversity. We conducted a white‐tailed deer (Odocoileus virginianus) exclosure experiment across a managed landscape to determine how deer impacts interact with the type of forest management system in influencing herb‐layer (all vascular ...
