Inner bark vs sapwood is the main driver of nitrogen and phosphorus allocation in stems and roots across three tropical woody plant communities

New Phytologist, Volume 239, Issue 5, Page 1665-1678, September 2023., 2023
Summary Nutrient allocation is central to understanding plant ecological strategies and forest roles in biogeochemical cycles. Thought to be mainly driven by environmental conditions, nutrient allocation to woody organs, especially to living tissues, is poorly understood. To examine the role of differences in living tissues (sapwood, SW, vs inner bark,

Assessing the distribution of elusive non‐game carnivores: are hunters valuable informants?

The Journal of Wildlife Management, Volume 87, Issue 4, May 2023., 2023
Our results show a high overall congruence but significantly different information provided by hunters and professionals on the distribution of the Egyptian mongoose, suggesting that both sources provide unique data for the management of non‐game species. Our findings stress the importance of engaging hunters in wildlife conservation, as they can share
