Responses Of Plant Functional Diversity To Long-Term Warming And Nitrogen Addition In A Desert Steppe, Y. Zhu, L. Tian, H. Y. Ren, G. D. Han

IGC Proceedings (1993-2023)

Plant functional traits are closely related to ecosystem functions, and can indicate changes in ecosystem functions. Plant functional diversity is an important component of biodiversity, which can more accurately predict the changes of ecosystem functions or processes than species diversity, and is the main determinant of ecosystem functions or processes. In order to study the impact of global climate change factors (i.e., warming and nitrogen deposition) on the plant functional diversity in a desert steppe, we conducted a long-term warming and nitrogen addition experiment in northern China for 15 years (2006 - 2020). In 2020, we measured the plant height, …

Evaluating Vascular Plant Composition And Species Richness On Horn Island, Mississippi, Using Passive And Active Remote Sensing In Conjunction With Ground Based Measurements, Kelly Lynn Lucas

Dissertations

Barrier island vegetation is subjected to chronic abiotic stressors combined with periodic storm events that favor species adapted to harsh environments. These islands are the first landforms to be affected by changes in coastal subsidence and sea-level rise. Evaluating changes in vegetation is important for understanding the impact of global climate change on coastal environments.

This study assesses vegetation composition and plant species richness on Horn Island, Mississippi using ground data in conjunction with remotely sensed spectral and LIDAR data. The goals of this research are to: 1) classify and map vegetation composition on Horn Island using hyperspectral and LIDAR …
