Although mountain wetlands in the Andes are of high conservation value and provide key ecosystem services to human populations that rely on them, they degraded by natural factors like tourism, overgrazing, climate change. Ecological restoration is an important tool foster their recovery, but selection indicators crucial order meet monitoring requirements with limited resources. This study proposes use a qualitative weighting matrix select ecological for restoration. We applied this...
Abstract America comprises three biogeographic regions: Nearctic, Neotropical and Andean. In between them, two transition zones (TZ) have been proposed: Mexican South American. The provinces belonging to a TZ no predominance of biotic elements pertaining each its bordering regions. Regarding the Andean region, one provinces, Patagonian Steppe, presents mixture different elements, which are typical zones. Because this, we assessed whether Steppe belongs region or it forms southernmost part...
Abstract Estimating organisms' responses to environmental variables and taxon associations across broad spatial scales is vital for predicting their climate change. Macroinvertebrates play a major role in wetland processes, but studies simultaneously exploring both community structure trait gradients are still lacking. We compiled global dataset (six continents) from 756 depressional wetlands, including the occurrence of 96 macroinvertebrate families, phylogenetic tree, 19 biological traits....
Environmental variables and benthic macroinvertebrate assemblages were spatially seasonally examined over two consecutive years (2000-2002) along a glacier snowmelt river in the central-west of Argentina where lies highest peak America, Mount Aconcagua (6956 m elevation). The goal was to assess seasonal altitudinal variability community structure define whether physical-chemical affect distribution aquatic insects. Mendoza basin characterised by high flow transparency, conductivity, hard...
The Bañado Carilauquen (BC) is part of the "Laguna Llancanelo" Watershed, an area international relevance for biodiversity conservation that holds interest oil production.Records on biological attributes system's waters are scarce, particularly regarding benthic macroinvertebrate assemblages.The goal was to study diversity malacofauna in BC and relationship between its distribution patterns water physicochemical parameters.Biological samplings records environmental parameters were carried...
The widespread use of plastic products in our modern life represents a serious threat to aquatic environments and wild animals that are exposed waste. Although microplastics (MPs) have been reported fish from several freshwater around the world, mountain little studied so far. occurrence MPs was assessed gastrointestinal tracts (GITs) non-native (rainbow trout Oncorhynchus mykiss brown Salmo trutta) native (torrent catfish Hatcheria macraei) Mendoza River Central Andes, Argentina.

Benthic invertebrate communities have been poorly studied in Andean streams apart from the Patagonian region. The primary objective of this work was to analyse faunal composition at three different altitudes and observe whether there were differences aquatic insect community structure spatial temporal scales. Physicochemical variables measured on a monthly basis. Sixteen families found, most frequent abundant taxa being Massartellopsis (Ephemeroptera), Andesiops Metrichia neotropicalis...
Three independent but complementary lines of research have provided evidence for the recognition refugia: paleontology, phylogeography and species distributional modelling (SDM). SDM assesses ecological requirements a based on its known occurrences enables distribution to be projected past climatological reconstructions. One advantage over other two approaches is that it provides an explicit link environment geography, thereby enabling analysis large number taxa in search more general...
Sigara (Tropocorixa) jensenhaarupi Jaczewski is the smallest species of subgenus ranging from 4.2-4.7 mm, and it characterized by absence a strigil, small narrow genital capsule with short hypandrium in males, shape abdominal tergite VII females. This endemic to Patagonian subregion (Andean region) Argentina. A monthly sampling study was performed during year northern Mendoza, additional material collected southern more precisely Bañado Carilauquen Llancanelo Lake Reserve (Malargüe...
Abstract The aims of this study are (i) to identify areas in the Andean region where climate will remain stable enough for survival species; (ii) analyze how change affect these under different scenarios; (iii) generate spatially explicit predictive maps expansion or retraction areas; and (iv) based on information, with priority conservation. analysis was performed using presence‐only data 14 Heteroptera Odonata species. Current future models were developed would be suitable small ponds,...
This study aimed to examine spatiotemporal variations in chironomid assemblages and detect how environmental variables affect their structure. We sampled seven streams at low high altitudes Northwest Argentina under contrasting climate conditions (Puna Chaco Serrano) during high- low-water periods. The that affected Chironomidae community structure were water temperature, conductivity, hardness, current velocity type of substrate. Fine substrates, gravel temperature favoured cold...
Torrent Ducks (Merganetta armata) inhabit rivers and streams across the Andes. The species feeds mainly on aquatic invertebrates occurs in with high flow rate, large emergent rocks, low anthropogenic disturbance. objective of this work was to study effect food availability environmental variables abundance two different levels anthropic disturbance diverse conditions. To describe each stream, we recorded density richness benthic macroinvertebrates physical-chemical variables, characterized...
The family Corixidae comprises a small group of true bugs that live in aquatic environments with abundant macrophytes. genus Ectemnostega Enderlein includes two subgenera: and Ectemnostegella, both known from South America, ranging Ecuador to Tierra del Fuego. (Ectemnostega) quadrata (Signoret, 1885 Signoret, M. V. 1885. 'Liste des Hémiptères recueillis la Terre de Feu para Mission Romanche'. Annales Société Entomologique France, 6: 63–70. [Google Scholar]) is distinguished by the widened...

Abstract Andean wetlands in arid climates are isolated ecosystems surrounded by steep terrain and have crucial relevance as a water resource. The species inhabiting them adapted to these habitats vulnerable environmental changes. aim of this study is evaluate the vulnerability invertebrate aquatic climate change organic pollution through an index from distributional models (SDM) score [vulnerability (Vais)], communities developed herein [wetland community (Wcv)]. Vais ranges 1 (highly...
The new species, Bembidion (Chilioperyphus) cuyanus (type locality ARGENTINA, San Luis, Quebrada Lopez, 7 km SE Francisco) is described, based on external structural features (extra setae in the supraorbital region, pronotum, elytral margin and intervals 3, 5 7) those of male genitalia (details endophallic flagellum). Line drawings illustrate diagnostic a key distinguishes among species subgenus Chilioperyphus Jeannel. This lives along border rivers creeks arid region western Argentina.KEY...
