“…During the rainy season (June-August), they come to the surface or to shallow zones, and aft er the end of the rainy season, in spring, summer and autumn, individuals are hidden in deep zones of their galleries (Rudolph, 2013 a, b). Th e associated communities of the habitats are poorly studied, with the exception of native forest wetlands at 38° S, where crustaceans such as amphipod Hyalella patagonica (Cunningham, 1871), isopod Heterias exul (Mueller 1892) and decapod Aegla araucaniensis (Jara, 1980) (Correa-Araneda et al, 2017) with high aquatic insect diversity (Correa-Araneda et al, 2021) were reported as associated fauna, which would be similar to the fi rst descriptions of fl ooded plains at the same latitude ( De los Rios Escalante et al, 2021).…”

“…Th e Chilean crayfi shes belongs to the Parastacidae family that contains the genera Parastacus, Samastacus and Virilastacus whose representatives inhabit between 32-46° S . One of them, Parastacus pugnax (Poeppig, 1835), is widespread in fl ooding plains called "vegas", streaching between 32-38° S (Rudolph, 2013 a, b;Velásquez et al, 2022) and forest wetlands at 38° S (Correa-Araneda et al, 2021, 2017. Th is species is the most studied and important as it is used for food in rural communities between 34-38°S regardless of seasonal change (Rudolph, 2013 b;Ibarra & Arana, 2012, 2011.…”

The burrowing crayfish Parastacus pugnax (Poeppig, 1835) inhabits the flooded plains in the central part of Chile (32–38°S), where it coexists with another representaives of invertebrate fauna. The aim of this study was to give the first description based on exploratory data of invertebrates associated to P. pugnax habitats in the Araucanía region, Chile. For comparison, published data on two similar habitats without P. pugnax populations were considered as outgroups. The obtained results revealed marked differences in species composition among sites with presence of P. pugnax, and without this species. A small number of species (1–5) was identified in the studied sites; Cladocera Simocephalus expinosus group was the most numerous and inhabited five of seven sites. Ecological and biogeographical topics were discussed.

“…Based on the results of the second national wetland resource survey on the north bank of the Hanjiang River in Chenggu County, this study was conducted a more comprehensive survey of the plant communities in the wetland patches on the north bank of the Hanjiang River in Chenggu County using the sample survey method. In accordance with the "Main Contents, Methods and Technical Specifications of the Inventory of Plant Communities", typical plant communities were randomly selected in each wetland patch, and standard squares of trees 5 × 5 m, shrubs, 2 × 2 m, herbaceous and aquatic 1m×1m were set up respectively (Correa-Araneda et al 2021, Ohore et al 2021. Forty plots were set up and the wetland type, geographic location, altitude, all species, number of plants, and coverage of the plant community were recorded where the plots are located.…”

Four water ecological surveys were carried out on the north bank of Hanjiang river in two seasons from 2020 to 2021. Based on the field wetland quadrat survey and literature data, the species diversity index was determined. The research showed that there are 360 species of wetland plants belonging to 108 families and 264 genera on the north bank of Hanjiang river, and the geographical composition of seed plants is at the genus level, mainly temperate distribution types, with 160 species. In the community species diversity index, the mean value of Patrick index was 18.80 ± 5.19. The mean Shannon Wiener diversity index was 2.15 ± 0.39. The mean value of Simpson dominance index was 0.81 ± 0.10. The average Pielou evenness index was 0.75 ± 0.10. The mean value of Margalef index was 3.44 ± 0.87. The Patrick index and Margalef index of the Bidens pilosa form were the lowest. The Shannon-Wiener diversity index，the Simpson index，and the Pielou index of the Potamogeton malaianus form were the lowest. The Patrick index of the Colocasia esculenta form was the highest,and the Pielou of the Sapium sebiferum form was the highest. The Shannon- Wiener diversity index and Simpson index of the Populus canadensis form group were the highest, and the Margalef index of the Flueggea virosa form was the highest. The research results provide basic data and scientific basis for the protection and restoration of wetland ecosystems and management of wetland resources in Yuan'an and similar areas. Bangladesh J.

“…The macroinvertebrate samples (n = 6) were extracted using a Surber net of 0.09 m 2 area and 250 μm mesh opening. To take samples, the Surber net was located upstream, washing the larger rocks in front of its entrance, and removing the thick substrate in order to extract the adhered individuals, in such a way that the organisms were dragged by the current to the bottom of the net (Figueroa et al, 2007;Correa-Araneda et al, 2021). The samples were previously cleaned in the field to remove the finest sediment, rocks, and woody material.…”

Extension of the known distribution range and habitat use of the Tiger Crab Aegla concepcionensis Schmitt, 1942 (Decapoda, Aeglidae)The tiger crab Aegla concepcionensis Schmitt, 1942 (Decapoda, Aeglidae) is a threatened freshwater decapod, endemic of Chile, with significant gaps in knowledge about its biology and ecology. The aim of this work was to contribute to the knowledge of the ecology of A. concepcionensis, through the extension of its known distribution range, recorded in a new type of ecosystem, and the description of the physicochemistry, vegetation and benthic macroinvertebrate and microalgal communities of those sites, which provides information about habitat use of the species. Our results show the presence of A. concepcionensis until 270 km south of the previously described range and reveal that the species inhabits streams and lakes. A. concepcionensis is associated to environments with cold and temperate waters, well oxygenated, with neutral pH and low conductivity, and characterized by low anthropic intervention, which is reflected in the high proportion of native riverine plant species and the high diversity of macroinvertebrate and microalgal benthic communities. We conclude that the previously restricted known distribution range of this species was mainly due to low sampling effort or misidentifications. Our results indicate that anthropic intervention should be avoided or minimized in the distribution area of A. concepcionensis, especially in those areas associated with urban expansion and touristic activities in streams and lakes.
