Los humedales representan una transición entre un ambiente terrestre y acuático, constituyéndose como uno de los sistemas naturales más importantes debido a sus múltiples funciones; no obstante, a pesar de su importancia, representan uno de los ecosistemas más vulnerables. Los humedales de la costa...
Resumen Los humedales, también llamados altoandinos, han sido poco estudiados y caracterizados en Costa Rica. En este estudio se analizan las características geomorfológicas, climatológicas e hidrológicas de los humedales altoandinos del Parque Nacional Chirripó (PNCh), ubicado al centro-sur de Cos...
Abstract The evaluation of ecosystem services is a tool to raise awareness about benefits of ecosystem functions for human well-being. In Brazil, few studies and reports assess ecosystem services in a watershed context. The aim of this paper is to fill this gap by assessing ecosystem services of Jacaré-...
Abstract Neosporosis is caused by an obligate intracellular protozoan, Neospora caninum . It is considered one of the most widespread and frequent causes of abortion in cattle worldwide. To evaluate the prevalence of anti-N. caninum antibodies and associated risk factors, serum samples were collected fr...

The analysis of animal movement patterns may help identify farm premises with a potentially high risk of infectious disease introduction. Farm herd sizes and bovine movement data from 2007 in the state of Mato Grosso, Brazil, were analyzed. There are three different biomes in Mato Grosso: the Amazon, Cer...
Abstract Human pressures have placed many tropical estuaries in developing countries under increased levels of stress. The Caroni Swamp Ramsar Site, the largest mangrove swamp along the west coast of Trinidad, has been subjected to high levels of anthropogenic impacts including hydrological alteration an...

This work is based in the investigation about the persistence of the use of medicinal plants in the communities inhabiting the wetlands within Iberá Natural Reserve. From the participant observation and semi-structured interviews, together with the collection of reference plants, the use of 90 medicina...
Abstract Streptomycetes remain as one of the important sources for bioactive products. Isolated from the mangrove forest, Streptomyces gilvigriseus MUSC 26T was previously characterised as a novel streptomycete. The high quality draft genome of MUSC 26T contained 5,213,277 bp with G + C content of 73.0%....

Resumen Los manglares son ecosistemas de importante productividad primaria, donde se establece un flujo de energía (nutrientes) con zonas adyacentes y su ambiente acuático, impulsado principalmente por los procesos de degradación. El objetivo del estudio fue estimar el coeficiente de degradación diar...
Abstract The Mexican tropical wetland is a coastal system with capacity to support the contamination derived from the extractive industry and the transformation of crude oil, due to its high plant biodiversity and the presence of rhizospheric reducing sulphate bacteria from plants tolerant to crude oil. ...
