An annotated checklist of freshwater Copepoda (Crustacea, Hexanauplia) from continental Ecuador and the Galapagos Archipelago.

An annotated checklist of the free-living freshwater Copepoda recorded in different regions in Ecuador (including the Amazon, the Andes, the coastal region, and the Galapagos Islands) is here provided. We revised all published records, critically evaluated the validity of each taxon and provided short taxonomic and biogeographical remarks for each one. A total of 27 taxa have been reported, including species and records at the generic level only.

Influence of environmental conditions on the prevalence of systemic hypertension in two riverine communities in the Amazon, Brazil.

This article discusses the influence of environmental conditions on the prevalence of systemic hypertension in two riverine communities in the Sustainable Development Reserve of Tupé, Manaus, Amazonas, Brazil, through an ecological study of multiple groups and contextual analysis carried out with the local inhabitants. To identify the environmental etiology describing the risk of disease development, the study compares demographics, incidence rates and common daily practices in these communities, using data collected in the field, between 2012 and 2014, as well as values provided by IBGE, originally from National Health Survey, 2013. The results suggest that social and environmental determinants, such as general living conditions, occupation and access to protective health care, in the investigated communities, are relevant factors in explaining the observed variability in systemic arterial hypertension (SAH) incidence rates.

Revision of the -group (Copepoda, Harpacticoida, Parastenocarididae): supplementary description of species, and description of the first semi-terrestrial from the tropical forest of Southeast Mexico.

Remaneicaris is a species-rich Neotropical monophyletic group, easily recognized by the synapomorphic position of the outer seta of the third exopodite of leg 4, localized at 2/3 of the outer margin. The genus, comprising 35 species in five monophyletic groups, plus R. ignotus and R.
