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 ...
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 ...
Predicting reproductive success in captive Puerto Rican parrots (Amazona vittata)
(2013)
The productivity of captive breeding programs can limit efforts to restore endangered species. The ability to accurately predict which captive pairs will breed successfully improves breeding productivity by allowing managers ...
Spatio-temporal changes of the herpetofaunal communities in Mount Resaca and Luis Peña Cay National Wildlife Refuges at Culebra Island, Puerto Rico
(2013)
La isla de Culebra, como parte del Banco Geográfico de Puerto Rico, ha sido un lugar el cual se han rezagado los estudios científicos. Estudios como el de Grant (1931) han servido de base para el presente trabajo. Los ...

(2013)
A cave is defined as any natural area below the earth's surface that extends beyond the dark zone and is accessible to humans. Caves are considered extreme environments for life that provide resources to oligotrophic ...

Evaluación cuantitativa de presas potenciales, tipo artrópodo, y análisis paisajista del hábitat potencial para la Reinita de Bosque Enano (Setophaga angelae) en Puerto Rico
(2013)
Setophaga angelae, the Elfin-woods warbler (EWWA), is an insectivorous bird endemic to Puerto Rico. Currently, two isolated populations of this species are found: one at the El Yunque National Forest, the other in the ...
Diversity of Actinobacteria associated with Nasutitermes costalis termite and their ability to inhibit the growth of entomopathogenic fungi
(2013)
The Actinobacteria are Gram-positive bacteria with high GC content, spore producers, and have the ability to produce antimicrobial agents. They are capable of degrading structural polysaccharides such as cellulose, ...
Effects of native and non-native grasses on woody species regeneration in a Puerto Rican subtropical dry forest
(2013)
Invasive non-native species can reduce native species diversity, alter ecosystem structure and produce barriers to restoration. However little is known about how native and non- native grasses may differ in their effects ...
Protonematal dispersal by water, wind, and animal
(2013)
Bryophyte dispersal allows population establishment, recruitment, and survival. This dispersal can be carried out in many ways, such as: water, wind, animal, and even gravity. The dispersal mechanisms have enabled the short ...
