“…More precisely, the indicators species analysis showed that significant changes in community structure occurred in this period, and Ephydridae were considered an indicator taxa of the 1st low, 1st normal, and 1st high discharge period, despite their low abundance. This inconsistency in association with different discharge periods, that is, regimes may indicate tolerance to discharge oscillations or could contribute to their overall low abundances which is in concordance with [ 35 ] who stated that Ephydridae in karstic springs when present are usually not abundant. A much clearer picture was painted by the other two indicator taxa determined for the spring site.…”

Most ecologists have used climate change, as an omnipresent pressure, to support their findings in researching the vulnerability of specific taxa, communities, or ecosystems. However, there is a widespread lack of long-term biological, biocoenological, or community data of periods longer than several years to ascertain patterns as to how climate change affects communities. Since the 1950s, southern Europe has faced an ongoing trend of drying and loss of precipitation. A 13-year research program in the Dinaric karst ecoregion of Croatia aimed to comprehensively track emergence patterns of freshwater insects (true flies: Diptera) in a pristine aquatic environment. Three sites, spring, upper, and lower tufa barriers (calcium carbonate barriers on a barrage lake system that act as natural damns), were sampled monthly over 154 months. This coincided with a severe drought event in 2011/2012. This was the most significant drought (very low precipitation rates for an extended period of time) in the Croatian Dinaric ecoregion since the start of detailed records in the early 20th century. Significant shifts in dipteran taxa occurrence were determined using indicator species analysis. Patterns of seasonal and yearly dynamics were presented as Euclidian distance metrics of similarity in true fly community composition compared at increasing time intervals, to ascertain the degree of temporal variability of similarity within the community of a specific site and to define patterns of similarity change over time. Analyses detected significant shifts in community structure linked to changes in discharge regimes, especially to the drought period.

“…Several studies have highlighted the great biodiversity of macroinvertebrates in springs as well as the presence of rare and endemic species (e.g., Takhteev et al 2010;Maiolini et al 2011;Kub ıkov a et al 2012;Martin & Brunke 2012;Spitale 2012;Spitale et al 2012). The uses and limitations of various methods for sampling benthic macroinvertebrates have been extensively discussed (e.g., Davies 2001).…”

Sampling in springs has several technical problems due to their reduced dimensions and habitat heterogeneity. A standardized quantitative method for sampling crenic macroinvertebrates has never been proposed. The aim of this study was to compare different sampling methods and consider their environmental impacts. First, we present a review of sampling methods found in the literature and discuss their advantages and disadvantages with respect to selective collection of the target community and habitat disturbance. Altogether, 10 different methods have been reported, the use of nets being the most common protocol. Second, we report the results of macroinvertebrate samplings performed in three springs, each surveyed twice, using three different methods (multi-habitat proportional hand net, baited traps, and vegetation washing), in order to compare their effectiveness in collecting macroinvertebrates. Overall, 32 macroinvertebrate taxa, mostly identified at family level, were collected in the sampled springs. Significant differences in abundances were found using different methods, while results for community structure were comparable between the hand net sampling and the combined use of the other two methods, notwithstanding slight differences in the composition of Coleoptera and Diptera assemblages. The hand net, with a multi-habitat proportional approach, yielded more thorough results, making it suitable for biodiversity inventories but having some potentially negative effects on spring habitats. Traps and vegetation washing are also reliable methods with negligible impacts on spring ecosystems that can be conveniently used in ecological studies.

“…Cyclopoid copepods and Acarina in the springs are typical of the alpine crenobionts in Europe (Gerecke et al, 1998;Staudacher & Fureder, 2007;Takhteev et al, 2010;Stoch et al, 2011). However, species richness of these groups was low in the bryophyte pools with only one species of Eucyclops and 6 Hydracarina.…”

Macroinvertebrate communities in spring-fed alpine source pools

et al. 2016

Three permanent alpine springs and their associated pools in the Australian Alps were studied over a summer season to understand their hydrochemical function and characterise the (previously unreported) aquatic macroinvertebrate communities. These ''source'' pools represent an extremely limited habitat within Australian alpine peatlands and are likely vulnerable to groundwater flow changes associated with climate change. The pools provide an extremely stable habitat for 30 macroinvertebrate taxa in the harsh alpine environment with near chemostatic conditions and pool temperatures constrained to 5.6-6.3°C despite air temperatures varying between -4.5°C and 30.6°C. Although small in area source pools have a significant effect on nitrate concentrations (decreases) and pH (increases) of waters flowing to downstream Sphagnum-dominated peatlands. The macroinvertebrate communities were distinctly different to that found in peatlands and headwater streams and were dominated by the amphipod Austrocrangonyx sp. (76.6% of total abundance), despite the low pH conditions (pH 5.27-5.56). Some of the macroinvertebrate taxa (Nannochorista, Anzacladius, and Parochlus) have a Gondwanan and circumAntarctic distribution, similar to the bryophytes that also occur in these pools (Bartramia and Blindia). These source pools contribute to the diversity of alpine fauna and should be separately recognised and protected.
