Ichthyofauna diversity of Taperoá II reservoir, semi-arid region of Paraíba, Brazil.
To determine the fish species present in Taperoá II Reservoir, and their relevance to the local economy, this research aimed to evaluate the composition, abundance, degree of dominance and constancy of species, along with diversity, richness, evenness and similarity indices in a tropical semi-arid fish assemblage, during one year. Six 24 hour-long samplings were carried out between October 2005...
متن کاملSeasonal dynamics of cyanobacteria in a eutrophic reservoir (Arcoverde) in a semi-arid region of Brazil.
Environmental conditions favor the predominance of dense populations of cyanobacteria in reservoirs in northeastern Brazil. The aim of this study was to understand cyanobacterial population dynamics in the rainy and dry seasons at two depths in the Arcoverde reservoir. Microalgae and cyanobacteria samples were collected during 24 hours with intervals of 4 hours (nycthemeral) at sub-surface and ...
متن کاملChromosomal diversity and phylogenetic inferences concerning thrips (Insecta, Thysanoptera) in a semi-arid region of Brazil.
The order Thysanoptera is composed of cosmopolitan phytophagous and predaceous insects with diverse life histories, behaviors and habits. This order is currently thought to form a trichotomy with Hemiptera and Psocodea; Hemiptera and Thysanoptera are considered to be sister groups. The interrelationships within Thysanoptera remain unclear and cytotaxonomic studies are scarce in thrips. We repor...
متن کاملEvaluation of Eight Evaporation Estimation Methods in a Semi-arid Region (Dez reservoir, Iran)
Establishing satisfactory estimation methods of lake evaporation has been crucial vital for research and management of water resources and ecosystems. Determining the accurate method to estimate evaporation from reservoirs in the investigation and management of water resources is very important. Hence, in this study eight empirical methods such as; Makkink, DeBruin-Kejiman, Penman, Priestley-Ta...
