(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 ...

(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, ...
Hyphomycetes associated with submerged bamboo leaves (Bambusa vulgaris) in Quebrada de Oro in Mayagüez, Puerto Rico.
(2008)
Leaf litter is a major source of nutrients for heterotrophic organisms in aquatic ecosystems in which microorganisms contribute significantly to the breakdown process of leaf litter. Fungi as aquatic hyphomycetes are ...
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 ...
Species richness of cyanobacteria, diatoms, and ciliates in microbial mats of the Cabo Rojo salterns, Puerto Rico
(2008)
Seasonal rains and the inflowof seawater into the Cabo Rojo salterns, Puerto Rico, induce changes in the concentration of dissolved salts. These environmental variations should have an effect in the composition and species ...
Nutrient release and grazing effects by two exotic Thiaridae snails on periphyton biomass under artificial conditions
(2018-05)
Thiara (Tarebia) granifera and Melanoides tuberculata are invasive parthenogenetic snails that impact food webs in tropical freshwater systems. Due to their high reproductive rate, both snails dominate the community of ...

(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 ...
