“…Furthermore, the mesohabitats of the mountain reservoirs had substrates mainly of concrete and devoid of vegetation. Similar to lowland ponds, aquatic vegetation in Alpine ponds constitutes a critical habitat for invertebrate diversity (García‐Criado, Martínez‐Sanz, Valladares, & Fernández‐Aláez, ; Hinden et al, ). Macrophyte cover is particularly important for dragonflies (Carchini, Solimini, & Ruggiero, ; Ilg & Oertli, ; Zwick, ).…”

1. Today, aquatic biodiversity suffers from many pressures linked to human activities, including climate change, which particularly affects alpine areas. Many alpine freshwater species have shifted their geographical distribution to colder areas, but a reduced availability of suitable habitats is also forecasted. New artificial water bodies could provide habitat enhancement opportunities, including small mountain reservoirs built to overcome a lack of snow during winter.2. To investigate the role of reservoirs as a habitat for freshwater invertebrates, a case study was conducted on eight reservoirs in the Swiss Alps. The study aimed to compare the water quality and freshwater biodiversity of the reservoirs with those of 39 natural and newly excavated ponds. Data were collected on physicochemistry, freshwater habitat structure, and aquatic insects (dragonflies and aquatic beetles).3. The study showed that the mountain reservoirs investigated did not differ from natural ponds in terms of surface area, conductivity, and trophic level. Similarly to natural ponds, reservoirs showed signs of impairment owing to surface run-off carrying pollutants linked to ski tourism. They presented a low diversity of mesohabitats, and in particular lacked vegetation. Compared with natural ponds, the species richness in reservoirs was lower for dragonflies but not for beetles. At the regional scale, the community from the reservoirs was a subset of the natural ponds community, supporting 38% of the regional species richness for these two insect groups. 4. The results suggest that mountain reservoirs are likely to be important for biodiversity in alpine areas, both as habitats and as stepping stones for species shifting their geographical range. These water bodies can be enhanced further by some nature-friendly measures to maximize benefits for biodiversity, including margin revegetation or the creation of adjacent ponds. Ecological engineering needs to be innovative and promote freshwater biodiversity in artificial reservoirs.

“…For comparisons of community composition, log-transformed abundance data (individuals per minute sampling) were used in a Non-metric Multidimensional Scaling (NMDS) analysis, based on Bray-Curtis similarity matrix and performed in R version 3.1.3. The maximum taxonomical resolution was used except for beetles, which were considered at genus levelthis same procedure was applied in other ecological studies in the same region (Martínez-Sanz et al, 2012;García-Criado et al, 2017).…”

“…The most common approach to the problem has been through spatial studies comparing ponds with varying hydroperiod. There is no doubt that temporary and permanent ponds support different macroinvertebrate assemblages (Jeffries, 1994;Gérard, 2000;Della Bella et al, 2005), even in Spanish mountain areas (García-Criado et al, 2017). In general, species richness of macroinvertebrates typically increases with increasing hydroperiod (Collinson et al, 1995;Spencer et al, 1999;Della Bella et al, 2005;Waterkeyn et al, 2008).…”

Current projections predict an intensification of hydrological drought as a consequence of climate change, but we know very little about the potential effects on aquatic communities. La Baña (SW León Province, Spain) is a mountain lake suffering from increased water seepage due to geological reasons. This has caused since 2005 a situation of hydrological drought, with pronounced reduction of lake area in late summer. The aim of this study was to assess the effects of this drought on the littoral macroinvertebrate assemblage. Macroinvertebrate samples were collected in 2005 (before the drought events became apparent), 2006 and 2014, as well as in a nearby temporary pond (only in 2014). The most evident change shown by the assemblage at La Baña was a drop in richness values. Rarefaction curves showed that richness in the lake in 2014 was, for an equivalent sampling effort, only slightly higher than that in the temporary pond, and much lower than that in the lake in 2005 or 2006. However, the assemblage composition did not shift toward a fauna typical of temporary waterbodies. The results might indicate that the resistance of the assemblage was high enough to prevent changes in the first moments (differences between 2005 and 2006 were small), but not after nine years of sustained summer drought.

“…For example, the spatial correlates of taxa in the ponds of Oxford County was reported which study area was 2608 km 2 (Briers & Biggs, 2005). However, in the survey of 51 alpine lakes and ponds in Castilla y León of Spain with an administrative area of 94223 km 2 , no spatial correlates of taxa was reported in most areas (Garcia-Criado et al, 2017). This supports the hypothesis that a common typology can be applied to a group of aquatic ecosystem with irregular distribution in a large-scale region.…”

Ponds are “islands” of independent habitats and research hotspots of regional biodiversity. This paper got some basic information about habitat conditions and aquatic macroinvertebrates in hilly ponds. Then we tried to provide a theoretical basis for the regional biodiversity conservation and sustainable development of the pond networks among basins. In this paper, the environmental and spatial variables concerned about aquatic macroinvertebrates in the ponds with different small basins of Liangping District, which is located in the east of Sichuan Basin, China, were investigated. The results showed that drainage basin effect did not occur among basins. The aquatic macroinvertebrates in the hilly ponds were mainly affected by altitude, nutrients, pH and other environmental factors. Within the basin scale, pond isolation was also one of the important factors affecting community structure. Considering the spatial pattern of the macroinvertebrate assemblages in the hilly ponds, the protection and management of those ponds need to focus on pond network other than a single pond, improve the habitat quality of the ponds, and ensure the cost-effectiveness and ecological benefits.
