Revision and phylogeny of the genus Pselaphomorphus Motschulsky, 1855 (Staphylinidae, Pselaphinae: Jubini).
(2012)
The Neotropical genus Pselaphomorphus Motschulsky, 1855 (Coleoptera: Staphylinidae: Pselaphinae: Jubini Raffray) is revised, including the redescription of P. sculpturatus Motshulsky, 1855 (Panama), P. longiceps Raffray, ...
Effects of food concentration in the competition between larvae of the introduced cane toad (Rhinella marina) and the native white-lipped frog (Leptodactylus albilabris)
(2012)
Invasive species are a major focus within conservation biology. The widely introduced cane toad, Rhinella marina, has gained particular interest in studies of effects of invasive species on native communities. In this study ...
Genetic Variation in the African Mitochondrial Haplogroup L3e in Puerto Rico
(2012)
This study aims to clarify the uncertainties of the African maternal origin of the Puerto Rico modern population that occurred during the slave trade. Haplogroup L3e was chosen for this study because it combines the ...
Detection of integron-encoded integrases in environments with moderate anthropogenic impact from Puerto Rico
(2012)
Integrons are genetic elements with a site-specific recombination system which includes an integrase (IntI) capable of capturing and expressing promoterless, circular DNA molecules known as gene cassettes. Although integrons ...
Drosophila as a versatile in vivo testbed for nanomaterial toxicity assessment.
(2012)
Dramatic advances in nanomaterials synthesis and characterization provide promising possibilities for biomedical applications. Consequently, there is a growing demand for well- characterized, low cost toxicity assays for ...
Revision and phylogeny of the neotropical subfamily Nyctiborinae (Dictyoptera: Blattaria: Ectobiidae)
(2012)
The neotropical cockroach subfamily Nyctiborinae Kirby, 1904 (Dictyoptera: Ectobiidae) is reviewed. A redescription for the subfamily and eight of its nine genera is undertaken, with emphasis on composition and morphology ...
Phylogenetic analysis and taxonomic revision of the neotropical genus Argentinomyia Lynch Arribálzaga, 1891 (Diptera: Syrphidae)
(2012)
The genus Argentinomyia Lynch Arribálzaga, 1891 (Syrphidae: Syrphinae: Bacchini), was taxonomically
revised and a phylogenic analysis was conducted. The monophyly and internal phylogenetic composition
of Argentinomyia ...
Ecology of the Asian clam, Corbicula fluminea (Müller), and its impact on the benthic invertebrates in Guajataca and La Plata Reservoirs, Puerto Rico.
(2012)
Corbicula fluminea (Müller, 1774) is one of the most invasive freshwater bivalves. It is nonnative
to America, where it has impacted the benthic macroinvertebrates and phytoplankton
communities of many lakes. The first ...
Generation of large-insert metagenomic libraries from subtropical hypersaline microbial mats and their screening for antibiotic resistance
(2012)
Most of the microbial diversity in an environment cannot be studied through laboratory standard media culture methods. For this, an emerging science, coined “Metagenomics”, has been developed as an effort to access the ...
Interaction between the fungus-growing ant Cyphomyrmex minutus and its symbionts at Cambalache Forest, Puerto Rico
(2012)
The ants in the tribe Attini cultivate a fungus (Basidiomycota: Agaricales) as food and protect it from specific mycoparasites, Escovopsis (Ascomycota: Hypocreales), using the antibiotic production capacity of Actinobacteria ...
