“…This difference may be explained in part by the presence in Patagonia, of Southern South American and Subantarctic species (Pugh et al, 2002;Dos Santos et al, 2008). An important factor here is that Southern Patagonia has a few subtropical species combined with Subantarctic species (Pugh et al, 2002;Dos Santos et al, 2008), whereas Northern Chile exemplifies a different faunal region (Menu-Marque et al, 2000;Morrone, 2006;De los Ríos-Escalante et al, 2012). In addition, in Chile, the Andes mountains represent a barrier that limits or prevents species dispersal between the two sides of the mountains and explains the marked differences in species reported from zones including Andean mountains (Morrone, 2006), compared to Southern Patagonia, where the mountains have practically disappeared and where it is possible to find many common species (Menu-Marque et al, 2000).…”

“…Data on inland water crustaceans were obtained from literature records (Araya & Zúñiga, 1985;Bayly, 1992;González, 2003;De los Ríos-Escalante, 2010;De los Ríos-Escalante et al, 2012;Jara, in press;Morales & Meruane in press;Rudolph, in press), and these were collated into a presence-absence matrix (Table 1, Fig. 1), with respect to the following six geographical zones: 1) Northern Chile: 18º-27ºS, 2) North-Central Chile: 27º-30ºS, Central Chile: 30º-38ºS, Northern Patagonia: 38º-41ºS; Central Patagonia: 41º-51ºS, and Southern Patagonia: 51º-55ºS.…”

ABSTRACT. The Chilean inland water crustaceans are characterized by a combination of endemic and cosmopolitan species: some occur throughout the territory of continental Chile, while others are restricted to specific latitudinal regions. This study examined the zoogeographical patterns exhibited by Chilean inland water crustaceans. We considered six regions: Northern Chile (18º-27°S), North-Central Chile (27º-30°S), Central Chile (30º-38°S), Northern Patagonia (38°-41°S), Central Patagonia (41º-51°S), and Southern Patagonia (51º-55°S), and these were identified based on literature records of inland water crustaceans. The classification analysis generated dendrograms for the following groups considered in this categories: all inland water crustaceans (Branchiopoda, Copepoda and Malacostraca), the zooplanktonic crustaceans (Branchiopoda and Copepoda), the Malacostraca alone, and each group separately. Analysis of total data and of the zooplankton group taxa alone revealed the existence of a main grouping consisting of the three Patagonian zones plus Central Chile, that is distinct from that of Northern Chile and North-Central Chile. Similarly, analysis of the malacostracan data revealed the existence of two main groups, one comprising the three Patagonian zones plus Central Chile, contrasted with a second group of Northern and North-Central Chile combined. Our results are in agreement with other panbiogeographical studies of South American crustaceans and insects. Possible factors responsible for generating this pattern are the dispersal and colonization potential of zooplanktonic crustaceans and the marked endemism of the malacostracans.

“…The literature about macroinvertebrates in this kind of rivers is quite fragmented, and mainly describes the presence of Malacostraca such as amphipods of the genus Hyalella (S.I. Smith), freshwater crabs of the genus Aegla (Leach, 1820), and the southern Chilean river prawn, Samastacus spinifrons (Phillippi, 1882) (De los Ríos-Escalante et al, 2012;Jara, 2013;Rudolph, 2013), and Diptera, Trichoptera and Ephemeroptera larval stages (Figueroa, 2000;Figueroa et al, 2003Figueroa et al, , 2007, many of these groups are currently endangered due to human-induced alterations in their habitats and the introduction of alien salmonids species since 1914 (Golusda, 1907(Golusda, , 1927Barros, 1931;Jara et al, 2006;Encina et al, 2017;Vega et al, 2017). The (introduced) salmonids, specifically, constitute non-selective, active predators (Soto et al, 2006(Soto et al, , 2007Fierro et al, 2012Fierro et al, , 2015Fierro et al, , 2016Piedra et al, 2012;Valdovinos et al, 2012;Vargas et al, 2010Vargas et al, , 2015.…”

First report of inventory and role of macroinvertebrates and fish in Cautín river (38° S, Araucania region Chile)

Abstract The Cautin river is located in the 137 years old Araucania region, Chile (38°S), and is characterized by alterations through human interference due agriculture and towns in its surrounding basin, the presence of salmonids, and by its mixed regime, originated from snow melting in summer and rains in winter. The aim of the present study was to make a review of the inventory and ecological role of the benthic inland water macroinvertebrates of the River Cautin, in order to understand their importance in the ecosystem of the river. The fauna of this river includes a fauna composed of endemic and introduced fish, which has, however, been only poorly studied until now. The literature revealed the presence of abundant populations of Diptera, Trichoptera and Ephemeroptera larval stages, and few crustaceans specifically amphipods and freshwater crabs along the river’s course. Many of these macroinvertebrates are prey for both introduced salmonids and native fishes. Similar results have been reported for other southern Argentinean and Chilean Patagonian rivers.

“…A different situation would occur with another similar widespread species (B. gracilis) which is found in coastal and mountain ephemeral pools, in mountain zones in Patagonia and tropical South America (Menu-Marque et al, 2000). The marked differences between inland water fauna in Patagonia and the north of South America (Menu-Marque et al, 2000;De los Ríos-Escalante et al, 2012) are due the absence of the physical barrier of the Andes mountains preventing species dispersion and the presence of migratory aquatic birds. This would explain the distribution patterns of branchiopods and copepods in the region(De los Ríos & Zúñiga, 2000;Menu-Marque et al, 2000).…”

The production of diapause eggs is a strategy for survival adopted by microcrustaceans living under adverse environments. This strategy also, aids dispersion and colonization in new environments. In the long term, this colonization process can enhanced genetic isolation as the first step in the process of species evolution. The present study is: (a) wider review of the diapause process in inland water crustaceans and its ecological, evolutionary and biogeographical implications, and (b) it's application to microcrustacean assemblages in inland waters in southern Patagonia. In the literature the diapause strategy was described from anostracans, cladocerans and copepods as microcrustaceans, and amphipoda in malacostracan crustaceans. High crustacean species richness was recorded from Southern Patagonia, this region having species of southern South American and Sub-Antarctic islands origin. Their spatial distribution is probably explained by the presence of migratory birds. Also, many habitats of the microcrustaceans are ephemerals, that would be studied under metapopulation and metacommunities view point.Key words: diapause, colonization, metapopulations, metacommunities, anostracans, cladocerans, copepods.
