Introduction
I am broadly interested in ecological niches and species distributions in time and space, eco-evo underpinnings of community assemblages, and ecological modeling of population abundance and dynamics. I use both endangered and invasive species across North American desert and tropical forest ecosystems for these empirical investigations. I also explore ethnobotanical uses and historical anthropogenic movement of plants. Please feel free to visit my site: https://tbisrael.wixsite.com/website

Preprint
Niche modeling for rare and range-restricted species can generate inaccurate predictions leading to an overestimation of a species geographic distribution. We used an iterative ensemble modeling approach and model-stratified field surveys to improve niche model formulation and better understand the ecological drivers of Ivesia webberi distribution....

For range-restricted species with disjunct populations, it is critical to characterize population genetic structure, gene flow, and factors that influence functional connectivity among populations in order to design effective conservation programs. In this study, we genotyped 314 individuals from 16 extant populations of Ivesia webberi, a United St...

African conservation scientists in the diaspora are still a largely untapped resource for conservation efforts in Africa. Institutions that harbor diaspora scientists from Africa should view their presence, motivation, and skills as an excellent opportunity to build strong bridges with the continent and undercut parachute science. Yet, parachute sc...

Ethnobiology, like many fields, was shaped by early Western imperial efforts to colonize people and lands around the world and extract natural resources. Those legacies and practices persist today and continue to influence the institutions ethnobiologists are a part of, how they carry out research, and their personal beliefs and actions. Various au...
Preprint
Habitat protection, by itself, is not sufficient to conserve range-restricted species with disjunct populations. Indeed, it becomes critical to characterize gene flow among the populations and factors that influence functional connectivity in order to design effective conservation programs for such species. In this study, we genotyped 314 individua...
