We also report phenotypic variation in the color pattern and scutellation on throat and pelvic regions of males from both eastern and western populations, which is described below. Furthermore, based on these new data, we confirm that the species is not fitting in its current IUCN category, and in consequence propose updating its conservation status.

  • Testing Sustainable Forestry Methods in Puerto Rico
    Herpetology Notes, volume 8: 141-148 (2015) (published online on 10 April 2015) Testing sustainable forestry methods in Puerto Rico: Does the presence of the introduced timber tree Blue Mahoe, Talipariti elatum, affect the abundance of Anolis gundlachi? Norman Greenhawk Abstract. The island of Puerto Rico has one of the highest rates of regrowth of secondary forests largely due to abandonment of previously agricultural land. The study was aimed at determining the impact of the presence of Talipariti elatum, a timber species planted for forest enrichment, on the abundance of anoles at Las Casas de la Selva, a sustainable forestry project located in Patillas, Puerto Rico. The trees planted around 25 years ago are fast-growing and now dominate canopies where they were planted. Two areas, a control area of second-growth forest without T. elatum and an area within the T. elatum plantation, were surveyed over an 18 month period. The null hypothesis that anole abundance within the study areas is independent of the presence of T. elatum could not be rejected. The findings of this study may have implications when designing forest management practices where maintaining biodiversity is a goal. Keywords. Anolis gundlachi, Anolis stratulus, Puerto Rican herpetofauna, introduced species, forestry Introduction The secondary growth forest represents a significant resource base for the people of Puerto Rico, and, if At the time of Spanish colonization in 1508, nearly managed properly, an increase in suitable habitat one hundred percent of Puerto Rico was covered in for forest-dwelling herpetofauna.

    United States In cooperation with Department of the Virgin Islands Agriculture Department of Planning Soil Survey of and Natural Resources; the Natural Virgin Islands Cooperative the United States Resources Extension Service; and the Conservation United States Department Service of Interior, National Park Virgin Islands Service 3 How to Use This Soil Survey General Soil Map The general soil map, which is the color map preceding the detailed soil maps, shows the survey area divided into groups of associated soils called general soil map units. This map is useful in planning the use and management of large areas. To find information about your area of interest, locate that area on the map, identify the name of the map unit in the area on the color-coded map legend, then refer to the section General Soil Map Units for a general description of the soils in your area. Detailed Soil Maps The detailed soil maps follow the general soil map. These maps can be useful in planning the use and management of small areas. To find information about your area of interest, locate that area on the Index to Map Sheets, which precedes the soil maps. Note the number of the map sheet and turn to that sheet. Locate your area of interest on the map sheet. Note the map units symbols that are in that area. Turn to the Contents, which lists the map units by symbol and name and shows the page where each map unit is described.

The relationships inferred from continuous maximum likelihood reanalyses of allozyme data were largely poorly supported. A similar analysis of the morphological data gave strong to moderate support for sister relationships of the two included distichoid species, the two trunk-crown species, the grass-bush species A. poncensis and A. pulchellus, and a clade of trunk-ground and grass-bush species. The results of maximum likelihood and Bayesian analyses of the 12S, cyt b, and combined mtDNA data sets were largely congruent, but nonetheless exhibit some differences both with one another and with those based on the morphological data. We therefore took advantage of the additive properties of likelihoods to compare alternative phylogenetic trees and determined that the tree inferred from the combined 12S and cyt b data is also the best estimate of the phylogeny for the morphological and mtDNA data sets considered together. We also performed mixed-model Bayesian analyses of the combined morphology and mtDNA data; the resultant tree was topologically identical to the combined mtDNA tree with generally high nodal support.

A taxonomic framework for typhlopid snakes from the Caribbean and other regions (Reptilia, Squamata). Caribbean Herpetology 49:1–61. Abstract The evolutionary history and taxonomy of worm-like snakes (scolecophidians) continues to be refined as new molec- ular data are gathered and analyzed. Here we present additional evidence on the phylogeny of these snakes, from morphological data and 489 new DNA sequences, and propose a new taxonomic framework for the family Typhlopi- dae. Of 257 named species of typhlopid snakes, 92 are now placed in molecular phylogenies along with 60 addition- al species yet to be described. Afrotyphlopinae subfam. nov. is distributed almost exclusively in sub-Saharan Africa and contains three genera: Afrotyphlops, Letheobia, and Rhinotyphlops. Asiatyphlopinae subfam. nov. is distributed in Asia, Australasia, and islands of the western and southern Pacific, and includes ten genera:Acutotyphlops, Anilios, Asiatyphlops gen.

    Adaptations of An Avian Supertramp: Distribution, Ecology, and Life History of the Pearly-Eyed Thrasher (Margarops fuscatus) Chapter 6: Survival and Dispersal The pearly-eyed thrasher has a wide geographical distribution, obtains regional and local abundance, and undergoes morphological plasticity on islands, especially at different elevations. It readily adapts to diverse habitats in noncompetitive situations. Its status as an avian supertramp becomes even more evident when one considers its proficiency in dispersing to and colonizing small, often sparsely The pearly-eye is a inhabited islands and disturbed habitats. long-lived species, Although rare in nature, an additional attribute of a supertramp would be a even for a tropical protracted lifetime once colonists become established. The pearly-eye possesses passerine. such an attribute. It is a long-lived species, even for a tropical passerine. This chapter treats adult thrasher survival, longevity, short- and long-range natal dispersal of the young, including the intrinsic and extrinsic characteristics of natal dispersers, and a comparison of the field techniques used in monitoring the spatiotemporal aspects of dispersal, e.g., observations, biotelemetry, and banding. Rounding out the chapter are some of the inherent and ecological factors influencing immature thrashers’ survival and dispersal, e.g., preferred habitat, diet, season, ectoparasites, and the effects of two major hurricanes, which resulted in food shortages following both disturbances. Annual Survival Rates (Rain-Forest Population) In the early 1990s, the tenet that tropical birds survive much longer than their north temperate counterparts, many of which are migratory, came into question (Karr et al. 1990). Whether or not the dogma can survive, however, awaits further empirical evidence from additional studies.

Caesio cuning is a reef-associated artisanal fishery, making it an ideal species for assessing regional patterns of gene flow for evidence of speciation mechanisms as well as for regional management purposes.

Wilkie, Chair This dissertation considers the social construction and negotiation of religion in a particular place and time: a small, relatively poor cotton plantation in the British Virgin Islands in the eighteenth century. Due to a rich record of archival documents and historical writings, we know that religion, race, class, and other forces of identification were at play on this site, but the specifics of many of the players—their relationships and worldviews—do not survive in texts. To reconstruct these, three seasons of archaeological work were initiated on the site, the home of the Lettsom family and the enslaved people they held. What makes this site unique to the region is the association with known members of the Religious Society of Friends, better known as “Quakers.” The owners, Mary and Edward Lettsom were members of a small group of Quakers which formed from the local planter population about 1740, and both professed Quaker values for the rest of their lives.
