Environmental resistance (ER) of native community, measured by similarities between native  and the invaded areas, may provide a complementary approach for predicting invasion risk when information on the niche or the identity of potential invaders is unknown. Using ER-based models, our research aims to identify the dominant drivers on the spread of invasive species and further predict the invasion dynamics under future climate. The research focus on invasive plants and animals in eastern US, and multiple ER measures are applied in ER models, including similarities in species assemblages, phylogenetic and functional traits, as well as similarities in climate, elevation, soil and human disturbances. These models were conducted for each invasive species and then evaluated by comparing the simulated results with the actual ranges. Finally, the invasion risk patterns and their future dynamics are revealed by overlapping the simulated ranges of all the species by their optimal ER model.

Social Science

Our research team is dedicated to understanding and addressing the complex social dynamics surrounding environmental and conservation issues. Below is an overview of our ongoing studies: 

  1. Topic Modeling Analysis of Invasion News: This study investigates how the media frames invasive species in the United States. By analyzing invasion science related news articles using latent Dirichlet allocation (LDA) topic modeling, we explore the impact of media representation on public perception and social action. Understanding these framing effects is crucial in shaping informed public opinion and effective conservation strategies. 
  1. Invasive Freshwater Fish Consumption Study: Partnering with the Florida Sea Grant Extension & Education Program, this project involves semi-structured interviews with food distributors, fish processors, and restaurants to understand the invasive freshwater seafood commodity chain. The insights gained from these interviews will help identify the challenges and opportunities within this industry, contributing to more sustainable and responsible practices in managing invasive species in freshwater ecosystems. 
  1. Perspectives on Biocontrol Framework: This manuscript proposes a new paradigm in biocontrol, emphasizing the need to balance risks with benefits in decision-making. We argue for a comprehensive risk-benefit framework that incorporates multiple capitals, aiming to streamline the process and improve the effectiveness of early detection and rapid response (EDRR) strategies. The study highlights the importance of rethinking current approaches to better address invasive species challenges. 
  1. Extension Efficacy Study: Partnering with UF/IFAS Invasive Species Council, this project is focused on quantifying the impact of extension work related to invasion science and management, this study explores the economic implications and the effectiveness of current outreach efforts. The team is developing proxy measures to evaluate situations where direct metrics are not feasible, aiming to enhance the overall efficacy of extension programs in promoting informed conservation practices. 
  1. Biocontrol Terminology Survey: Partnering with UF/IFAS Fort Lauderdale Research and Education Center, this survey seeks to understand the effectiveness of different terminologies used in biocontrol outreach. By assessing whether alternative terms are more effective in gaining public acceptance, the study aims to refine communication strategies that support biocontrol efforts and improve public understanding of its benefits. 

Through these studies, we are committed to advancing knowledge and developing practical solutions that support sustainable environmental management and conservation efforts.
