No guts, no reef: Understanding the microbiome, genetic diversity, and phylogenetic relationships of the Puerto Rican long-spined black sea urchin, Diadema antillarum, a keystone species of the Caribbean reef
(2020-11-17)
In this paper we describe the gut microbiome of the Puerto Rican keystone sea urchin Diadema antillarum. We also used next generation sequencing of the cytochrome b region to examine the phylogenetic relationships among ...
Plant functional diversity across two elevational gradients in serpentine and volcanic soils of Puerto Rico
(2020-05-29)
Mountains are model systems for understanding the mechanisms that underlie patterns of biodiversity and ecosystem function. This study disentangles the effects of climatic and edaphic properties on patterns of trait variation ...
Effects of forest cover on the recovery of diurnal butterflies (Lepidoptera Papilionoidea) after an extreme disturbance in subtropical humid forests of Puerto Rico
(2020-05-28)
Butterflies represent a model taxon in biodiversity and conservation studies; yet few studies have documented changes in butterfly abundance over time in tropical ecosystems, especially in Puerto Rico or the Caribbean where ...
Molecular and morphological characterization of Rhodobacter sphaeroides 7001 bacteriophages øR3-PR6 and øR3-PR7
(2020-05-26)
Bacteriophages are ubiquitous viral particles found in most environments, such as oceans, rivers, and soil. This wide distribution makes phages one of the most abundant viral types on the planet. Bacteria are outnumbered ...
Environmental correlates of the distribution and size of the land snail Caracolus marginella (Gmelin 1791) and the number of micro-invertebrates associated with its feces in a secondary forest at Mayaguez, Puerto Rico
(2020-12-09)
Phoretic micro-invertebrates use animals, such as snails, as hosts or for dispersal mechanisms through host feeding and feces. Here we studied the number of micro-invertebrates associated with the feces of the land snail ...
Distribution of Harpellales (Kickxellomycotina) in Culicidae and Chironomidae in Urban sites in Mayagüez and Arecibo, Puerto Rico
(2020-05-29)
Harpellales fungi are obligate symbionts. They need a live host in order to grow and reproduce. They are found in the digestive tract of various arthropods (including insects), attached without penetration to the gut lining. ...
Genetic characterization of host-microbiome-pathogen dynamics in ancient Amerindians of Punta Candelero, Puerto Rico
(2020-10-27)
This thesis seeks to address the deficit of ancestral human references from the tropics, specifically the Caribbean, by adding genetic (genomic and microbiomic) information from the ancient Puerto Rican Amerindian population ...
