Phenology of tropical dry forests in the Caribbean
(2018-01-23)
Tropical dry forests exhibit difficulties in the identification of phenological patterns of plants and changes in functional traits of animals in response to climatic variables. Our goal is to determine how the phenology ...
Cianobacterias en la bahía de Mayagüez: abundancia, distribución y su relación con las propiedades bio-ópticas.
(2007)
Mayagüez Bay is a complex environment with variety of physical and biological processes
influencing the spatial and temporal variability of bio-optical properties. This research
focused on the role of cyanobacteria because ...
Function of song type matching in Adelaide’s Warbler (Setophaga adelaidae) in Cabo Rojo Wildlife Refuge (Cabo Rojo, Puerto Rico)
(2013)
Many species of birds sing the same song-type that a neighbor has just sung, a behavior known as song-type matching. Song-type matching has long been considered a signal of aggressive intent, but recent experiments fail ...
Purification and kinetic characterization of trypsin from the intestine and pyloric caeca of the white grunt, Haemulon plumierii, (Lacepède, 1801)
(2004)
Trypsin is one of several animal digestive proteases whose activities collectively
breakdown ingested proteins to facilitate gut amino acid absorption. The goals of this
research were to purify and characterize trypsin ...
Abundancia y distribución de Pontodrilus litoralis en las costas cercanas al Faro de Cabo Rojo, Puerto Rico
(2010)
The purpose of this investigation was to determine the structure and dynamics of
the populations of the oligochate Pontodrilus litoralis on the coasts near the Cabo Rojo
Lighthouse in Puerto Rico. During the months of ...
Movement, habitat use and diet of an invasive snake, boa constrictor (boidae), in Puerto Rico
(2018)
Invasive species are the second threat to biodiversity. Studies have suggested that along with other variables, lack of predators, numerous offspring production, body size and prey availability are some of the reasons for ...
Signatures of selection in the indel-containing coding sequences from human to primate genome comparisons
(2013)
Gene sequences are relatively conserved, and usually show few differences in comparisons between closely related species, such as between humans and non- human primates. In this study, we focused on >10 bp insertions and ...
Wedelia trilobata (L.) Hitchc. (Asteraceae) como repelente de Bemisia argentifolii Bellows & Perring (Homoptera: Aleyrodidae) y de Cosmopolites sordidus Germar (Coleoptera: Curculionidae)
(2001)
Laboratory experiments were conducted to understand the influence of Wedelia
trilobata (L.) Hitchc. on the oviposition of Bemisia argentifolii Bellows & Perring over
tomato leaves and on the presence of Cosmopolites ...
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, ...
Possible role of adenine and thymine rich sequence in the encapsidation pattern of Parvovirus LuIII
(2007)
LuIII is a small, non-enveloped, icosahedral autonomous parvovirus that contains a small
linear (5 kb) single stranded DNA genome and infects human cell lines lytically with no
evidence of integration into cellular DNA. ...
