The use of ecoregions to classify stream and river environments has been extensively tested in North America Europe, but few such studies have conducted South America. In this study we whether taxonomic richness, composition, organism abundance within benthic macroinvertebrate assemblages were associated with northwestern Argentina at the genus family levels. We included 3 their respective subecoregions study: Yungas subtropical cloud forest, Western Chaco dry Monte xeric shrublands. used...
In the Northwestern region of Argentina (NOA), an extensive part territory is occupied by arid environments, vulnerable to development human economic activities. The aim this study was provide basic information about benthic macroinvertebrate assemblages rivers in area, and use different biotic indices prove their power predict river ecological status. Fifteen streams were sampled provinces Catamarca La Rioja, occasions, accounting for a total 23 sites. Samples taken with Surber net (two or...
The genus Languidipes is currently represented by three species distributed in southeastern Asia, India, and Sri Lanka. corporaali the most widely species, both, male female imagos, as well nymphs, are known. In contrast, other L. taprobanes lithophagus , only known from nymphs. Here, we describe a new janae sp nov, based on imagos collected Borneo, Indonesia. This characterized presence of ommation mesonotum, penis almost completely divided, with sub-quadrate base small outer projection...
We studied the diversity, distribution and ecology of Hyalella (a genus endemic to America that lives over a wide range geographical altitudes) in 44 peatlands Puna Altos Andes ecoregions, NW Argentina, mostly placed provinces Salta Catamarca. Our aim is deepen our understanding these freshwater crustaceans both ecoregions. Field collection was made between 2013 2017, ecogeographical variables were also recorded. The identified by dissections under microscope. estimated biodiversity indices...
Abstract Aquatic insect growth is tightly linked to environmental temperature. Growth rate tends increase with rising temperatures. integrates different factors related population fitness, being partly responsible for species distribution. We aim estimate daily rates from mayfly nymphs reared under thermal regimes in the field, during five periods 2016 2018. Twelve of mayflies were mesocosms six streams (from three altitudinal levels a mean elevation 725, 1069, and 1509 m.a.s.l.)....
Secondary production is the formation of heterotrophic biomass across time, which integrates several important ecological processes that affect life organisms, populations, communities and ecosystems, but its study has poor developed in South America. The objectives this work were to describe diversity benthic macroinvertebrate assemblages terms abundance biomass, quantify their secondary for first time Andean rivers. A quantitative sampling scheme was implemented, using a Surber sampler,...
Our aim was to investigate the larval development of Argia joergenseni Ris in three streams located at different latitudes and ecoregions (Yungas Chaco) Argentina. We measured head width metathoracic wing sheath length, classified larvae into five size classes. results showed patterns growth between study sites. At Yungas sites (latitude 26º S), exhibited a high proportion small individuals throughout year, suggesting multivoltine life cycle. In contrast, Chaco region 32º S) marked...
