Ion-specific standards are needed to protect biodiversity
Abstract Freshwater ecosystems are the most threatened worldwide. Argentinian‐protected areas have been established mainly to protect vertebrates and plants in terrestrial ecosystems. In order create a comprehensive biodiverse conservation plan, it is crucial integrate both aquatic systems include macroinvertebrates. Here, we address this topic by proposing priority of including invertebrates, ecosystems, their connectivity land uses. Location: Northwest Argentina. We modeled ecological...
A new approach for biogeography to find patterns of sympatry, based on network analysis, is proposed. Biogeographic analysis focuses basically sympatry species. Sympatry a (= relational) datum, but it has never been analyzed before using relational tools such as Network Analysis. Our biogeographic consists two parts: first the inference and second method (NAM). The was designed propose hypothesis, constructing basal punctual data, independent priori distributional area determination. In this...
Checklist and catalog publications demonstrate a clear connection between basic taxonomy biodiversity issues. According to some estimates, only 10-30% of all global species have been named. As in other fields, catalogs provide an important source information concerning diversity freshwater ecology. South America is continent dominated by ecosystems. The tremendous habitat created this landscape supports high number arthropods, including water mites, which belong the hyperdiverse group Acari....
The aims of this work were to describe the conservation status riparian forests located in a mountain subtropical basin Tucumán province, Argentina, and assess how quality is related with altitude, plant species richness, proportion exotic species, Total Suspended Solids (TSS) adjacent rivers. Composition richness studied at 16 sites along an altitudinal gradient TSS was determined from water samples collected each site. In order evaluate forests, we calculated index Quality Yungas Riparian...
Abstract Conversion of high mountain forests into pastures or croplands and changes in land uses have produced hydrology, vegetation cover terrestrial aquatic linkages, resulting increased nutrient loads on water bodies. The developing countries today need to obtain an indicator response signature under multiple stressor scenario, identify causes bodies impairment. Intermountain use impact a Subtropical Andean River was studied Tucumán province, Northwestern Argentina. Benthic...
Non-target species from agricultural areas might be exposed to sublethal pesticide concentrations favoring survival and reproduction of the resistance individuals. The objective this study was evaluate chlorpyrifos toxicity detoxification enzymatic activities on three (Hyalella curvispina, Heleobia parchappii Girardia tigrina) a drain channel with history insecticide contamination (EF) Neuquén river (NR) in Argentina. Chlorpyrifos amphipods (H. curvispina) planarians (G. NR about six-...
Existing classifications of benthic and interstitial freshwater invertebrates are described discussed. A classification is proposed for southern neotropical (south latitude S 15) water mites in relation to their life style habitat preferences. The includes planktonic, superficial, benthic, thermal, subterranean forms. diversity the Hydrachnidia family genera (22 families, 97 genera, 521 species) then analyzed using new classification. Ubiquitous stygobites deserve special consideration...
Hydrachnidia water mites were examined in eight streams with similar chemistry from two sub-catchments that did not differ respect to precipitation predictability (P>0.05). This study describes the structure of this taxonomic segment invertebrate community as species diversity, relative abundance, and composition. Twenty-two mite found study. Following rarefaction sub-samples 170 individuals, expected richness for these subtropical was lower (E<16) than a tropical stream (E=23)....
Ecología Austral, 25:26-36 (2015)Salinity of rivers is an expression the concentration salts dissolved in water body. Secondary salinization increase salinity a body as result human activity. Salinity may restrict species composition aquatic biota to tolerant species. In this study we analyzed benthic communities and their relationship with physicochemical variables natural pristine systems impacted environments. We collected community samples using D-net for laboratory major ions analysis....
a. Land use was observed in variation the concentration of 5 physicochemical variables.b.Buffer strip (0-150m) affected for land shows a diminished filter capacity.c.Phosphate detected water is attributed to capacity buffer strip.d.Different fertilizers used subtropical crops affect river water.e. Riparian vegetation replacement >60% affects ability pollutants.
A male exemplar identified as Omartacarus brevipalpis Cook, collected in Tucuman (Argentina), is reassigned to O. tucumanensis Fernández, the nymph described by Cook 1980 near type locality of tucumanensis. New distributional data are presented for and Meramecia (Submeramecia) diamphida Cook. saltensis Fernández assigned subgenus Parameramecia, where it second species at present.
We describe the historic sequence of application aquatic bioindicators in Argentina and feasibility for being disseminated incorporated as biomonitoring tools environmental management. In parallel, we present development stages followed Ecuador Spain. Indices from other countries were first applied, these later adapted to local flora fauna or reformulated different ecoregions. The indices applied depended on each ecoregion impact evaluate. transfer management was carried out all cases a slow...
Aquatic mites show a great morphological variability and inhabit diversity of freshwater habitats, especially taking advantage the complexity resources provided by South American aquatic plants. The relevance in microhabitat not studied so far about Amazonian macrophyte plants Andean filamentous algae is analyzed. A new species mite described, with it, genus Piona Arrenurus amazonicus are recorded for first time Colombian rivers; records Sperchon neotropicus associated Cladophora sp....
