Jaime Collazo

About

Jaime Collazo is a Professor and Assistant Unit Leader at the NC Cooperative Fish and Wildlife Research Unit within the Department of Applied Ecology at NC State University. He earned his Ph.D. in Animal Ecology from Iowa State University in 1985. His research focuses on population dynamics across various taxonomic groups, with particular emphasis on avian species and endangered species research and management. Collazo's work includes studying species-habitat relationships, range dynamics, and the implications of climate and landcover change on species persistence, as well as developing adaptation strategies. His lab programs are associated with the Biodiversity and Spatial Information Center, and he collaborates with several research organizations including the North Carolina Wildlife Resources Commission, US Geological Survey, and the Wildlife Management Institute.

• High‐resolution dynamically downscaled rainfall and temperature projections for ecological life zones within Puerto Rico and for the <scp>U.S.</scp> Virgin Islands

  International Journal of Climatology · 2020 · 32 citations

  The Weather Research and Forecasting (WRF) model and a combination of the Regional Spectral Model (RSM) and the Japanese Meteorological Agency Non-Hydrostatic Model (NHM) were used to dynamically downscale selected CMIP5 global climate models to provide 2-km projections with hourly model output for Puerto Rico and the U.S. Virgin Islands. Two 20-year time slices were downscaled for historical (1986-2005) and future (2041-2060) periods following RCP8.5. Projected changes to mean and extreme tempe…

• Estimating bee abundance: can mark-recapture methods validate common sampling protocols?

  Apidologie · 2022 · 26 citations

  Abstract Wild bees can be essential pollinators in natural, agricultural, and urban systems, but populations of some species have declined. Efforts to assess the status of wild bees are hindered by uncertainty in common sampling methods, such as pan traps and aerial netting, which may or may not provide a valid index of abundance across species and habitats. Mark-recapture methods are a common and effective means of estimating population size, widely used in vertebrates but rarely applied to bee…

• Climate change is creating a mismatch between protected areas and suitable habitats for frogs and birds in Puerto Rico

  Biodiversity and Conservation · 2021-07-27 · 21 citations

  articleOpen access

  Abstract Climate change is altering the spatial distribution of many species around the world. In response, we need to identify and protect suitable areas for a large proportion of the fauna so that they persist through time. This exercise must also evaluate the ability of existing protected areas to provide safe havens for species in the context of climate change. Here, we combined passive acoustic monitoring, semi-automatic species identification models, and species distribution models of 21 b…

• The influence of floral resources and microclimate on pollinator visitation in an agro-ecosystem

  Agriculture Ecosystems & Environment · 2020 · 21 citations

  As agriculture expands to meet the needs of a growing global population, natural ecosystems are threatened by deforestation and habitat fragmentation. Tropical agroforestry systems offer a sustainable alternative to traditional agriculture by providing food for production while also supporting biodiversity and ecosystem services. Previous studies have shown that these systems may even improve crop pollination, but the mechanisms of how these improvements occur are still poorly understood. Using…

• Survey design optimization for monitoring wildlife communities in areas managed for federally endangered species

  Animal Conservation · 2021-03-01 · 10 citations

  articleSenior author

  Abstract In wildlife communities composed of federally endangered species, there are often several species of conservation concern that have not yet warranted federally mandated protection. These species often need continued monitoring to inform the direction of future management. While recovering endangered species is an important conservation goal, practitioners are challenged by balancing federally mandated protocols with actions that promote non‐listed priority species. Practitioners need an…
