The 2023 IPBES Invasive Species Assessment indicates that more than 3,500 invasive species with documented negative impacts have been recorded worldwide. Although their numbers are likely to be underestimated and expected to increase, 461 vertebrate species contribute to that statistic, including mammals, birds, reptiles, amphibians, and fishes.
Crytser’s research investigates the dietary shifts of såli (Micronesian starlings – Aplonis opaca) in response to the brown tree snake (Boiga irregularis) invasion on Guam using stable isotopes to access trophic dynamics.
Thematic Area(s):
Dr. Czuba’s research focuses on the transport of water and sediment in streams and rivers and how that affects the distribution of invasive and native aquatic species, including fish, macroinvertebrates, freshwater mussels, and plants.
Thematic Area(s):
A key component of Dr. Escobar’s research is developing theory and methods to study the biogeography of infectious diseases, disease ecology, and invasion biology. Current projects include bat-borne rabies, chronic wasting disease, spatial epidemiology in the Anthropocene, and disease-biodiversity relationships.
Thematic Area(s):
Jain’s research explores plant-seed disperser interaction networks in the Central Appalachian Mountains.
Thematic Area(s):
Dr. Larsen-Gray’s research focuses on wildlife ecology in private, working forests throughout the eastern United States.
Thematic Area(s):
Dr. Mims’ research investigates how species’ traits and environmental attributes interact to influence community and population structure of aquatic organisms. Her overarching goal is to uncover, understand, and predict differential response of aquatic species to a changing landscape and climate.
Thematic Area(s):
Dr. Moore has studied the behavioral ecology and physiology of reproduction and stress in invasive species. Vertebrates of interest include tropical birds, reptiles, and amphibians.
Thematic Area(s):
Dr. Nyboer is a freshwater ecologist and conservation scientist exploring how anthropogenic stressors affect freshwater ecosystems and the fish, fisheries, and fishing communities they support.
Thematic Area(s):
Dr. Reid studies ecological restoration and community assembly in tropical and temperate terrestrial ecosystems.
Thematic Area(s):
Ripa is researching how to limit non-native plant invasion of stream restoration projects and how both restoration and invasion might impact the soundscape, particularly as it relates to anuran communities.
Thematic Area(s):
Dr. Rogers’ research focuses on population and community ecology, plant-animal interactions, seed dispersal, pollination, food web dynamics, tropical biology, ecosystem services, and conservation. A majority of the research is conducted on the Mariana Islands, where due to the introduction of the brown tree snake, Guam’s forests are now functionally without birds.
Thematic Area(s):
Dr. Buyuktahtakin Toy’s research explores optimal management of invasive species with mathematical modeling and artificial intelligence. Past species of interest include the emerald ash borer in North America, Sericea Lespedeza in the Great Plains, and buffelgrass in the Sonoran Desert.
Thematic Area(s):
The Invasive Species Collaborative (ISC) at Virginia Tech aims to position the university as a center of excellence in the science, policy, and management of invasive species by bridging disciplinary divides, driving innovative solutions, and engaging in team science.
