Plant-Insect Interactions: Do herbivores restrict the reproductive output of Spathoglottis plicata?
Vega, Carlos J.; Ackerman, James D.; Cuevas Padro, Ana A. (External Scientific Advisory Committe (ESAC), 2009-11)Many exotic plants have naturalized in Puerto Rico, some of which may pose a threat to native species. One such exotic is Spathoglottis plicata, an orchid native to Southeast Asia. Popular as an ornamental, this orchid has ... -
The Reproductive Biology of Zamia (Cycadales: Zamiaceae) in Puerto Rico: Implications for Patterns of Genetic Structure and Species Conservation
Lazcano Lara, Julio C. (2015-05)dc.description.abstract Variation in plant reproductive success is affected by how ecological conditions interact with a plant’s sexual, mating, and pollination systems. Long-term viability of natural populations is dependent ... -
Roadside Ménage à Trois: A Native Pest on an Exotic Orchid Weed Defended by Ants?
Espino, Isamalish; Cuevas-Padró, Ana Almisa; Ackerman, James D. (External Scientific Advisory Committe (ESAC), 2009-11)The resource concentration hypothesis states that herbivores are more likely to find and remain on hosts that are growing in dense stands. Some areas in the Rio Abajo Reserve of Puerto Rico have dense populations of ... -
Spatial Distribution and Performance of Native and Invasive Ardisia (Myrsinaceae) Species in Puerto Rico: The anatomy of an invasion
Carolina Muñoz, Marcia; Ackerman, James D. (External Scientific Advisory Committe (ESAC), 2009-11)Establishing and spread of invasive species into new habitat is considered the second most significant threat to biodiversity worldwide, this is in part due to displacement and extinction of native species. However, the ... -
There goes the neighborhood: Reproductive success of Bletia patula when Spathoglottis plicata moves in
Recart, Wilnelia; Cuevas, Ana A.; Ackerman, James D.; Flores-Saldaña, Nadia P.; Zambrana-Torrelio, Carlos M. (External Scientific Advisory Committe (ESAC), 2009-11)Naturalized exotic species are homogenizing the earth’s biota and are increasing densities of pests in newly colonized areas. When exotics change ecosystems and affect native species, then they are invasive. Do high density ...
