Cytogenetic analysis of two locariid species (Teleostei, Siluriformes) from Iguatemi River (Parana River drainage) in Brazil
Fishes of the Loricariidae family, known as "cascudos", constitute an endemic group in Neotropical freshwaters. In this study, were cytogenetically examined two species of Loricariidae (Pterygoplichthysanisitsi Eigenmann & Kennedy, 1903 and Farlowellaamazonum (Günther, 1864) belonging to Hypostominae and Loricariinae subfamilies respectively) from Iguatemi River. Our study provide the first des...
متن کاملThe distribution of scaled chrysophytes in the delta region of the Parana River, Argentina
A total of 33 taxa of scaled chrysophytes were observed from 50 localities in and around the delta region of the Parana River, situated in the subtropics of Argentina. The study sites were divided into five groups based on their physical and chemical characteristics and location within the delta complex. The five groups included waterbodies situated on the delta, channels of the river, tributar...
متن کاملStormflow hydrochemistry of a river draining an abandoned metal mine: the Afon Twymyn, central Wales.
Contaminated drainage from metal mines is a serious water-quality problem facing nations that exploit metal mineral resources. Measurements of river hydrochemistry during baseflow are common at mine sites, whilst detailed hydrochemical information regarding stormflow is limited and often confined to a single event. This study investigates the seasonal evolution of stormflow hydrochemistry at an...
متن کاملThe Drosophila community in xerophytic vegetations of the upper Parana-Paraguay river basin.
The genus Drosophila is the most abundant in the Drosophilidae family. Some species are endemic to certain regions and others are cosmopolitans. In Brazil, there are several ecosystems to explore regarding the composition and ecological aspects of Drosophila. Xerophytic areas are an example. They can be found in the South and Southeast of Brazil as islands, a result of paleoclimatic cycle chang...
متن کاملErs-2, Radarsat Sar Backscattering Characteristics of the Parana River Delta Wetland, Argentina
The Lower Delta Islands of the Paraná River in Argentina constitute a major coastal tidal freshwater wetland located at the De La Plata River estuary, very close to Buenos Aires City. It is a complex region where the landscape pattern is characterized by mosaics of natural and man made ecosystems. Since the last few years an increased number of SAR images have been available for monitoring coas...
