Abstract This study aimed to model the habitat suitability for an invasive clam Corbicula fluminea in a coastal shallow lagoon in the southern Neotropical region (–30.22, –50.55). The lagoon (19km2, maximum deep 2.5m) was sampled with an Ekman dredge in an orthogonal matrix comprising 84 poin...
ResumenEl pez león (P. volitans), ha invadido todo el Caribe mexicano y Golfo de México, con un potencial de causar impactos negativos en el arrecife. En el sur del Caribe Mexicano se registró por vez primera en julio 2009, y a seis años del primer reporte, se han implementado algunas medidas de cont...
Carijoa riisei (Octocorallia: Cnidaria), a western Atlantic species, has been reported in the Pacific as an invasive species for nearly forty years. C. riisei has been recently observed overgrowing native octocorals at several rocky-coral littorals in the Colombian Tropical Eastern Pacific-(TEP). C. riis...
La introducción de especies de peces ha sido considerada como uno de los problemas más difíciles de conservación de la biodiversidad, ya que la degradación de los ecosistemas naturales que ha venido ocurriendo en todo el mundo ha provocado que las especies no nativas se establezcan y se conviertan e...
This study aimed to describe the early development of Clarias gariepinus, a species that has been introduced into various watersheds worldwide, in order to help the identification of its eggs, larvae and juveniles in natural environments. The material used was obtained via induced spawning during 1999. A...
Species of peacock bass were introduced in several watersheds in South America and worldwide, mainly due to its importance to sport fishing, by being a fighting fish. A recent revision of the genus Cichla showed that the species introduced in reservoirs of the South, Southeast and Northeast regions of Br...
Floristic and structural characterization of three secondary forest fragments in Costa Rica. Observations on successional development and floristic composition were made in 25 plots (10x2 m) established in three contiguous secondary forest fragments of the Lankester Botanical Garden, Costa Rica. Human ac...
The formation of the mountain ranges of Costa Rica and western Panamá, as well as the cold climatic conditions that prevailed during the upper Pleistocene, played a crucial role in determining the bird species composition of the highlands in this region. Glacial conditions favored dispersal movements of...
Based on long-term studies in the upper rio Paraná basin, in addition to a broad review of literature and other information, we were able to identify 33 species of native fishes in the lower rio Paraná basin that successfully colonized the upper rio Paraná after Itaipu impoundment, that flooded the na...
