“…It seems clear that many of the invertebrate taxa that colonised Skälby Dämme corroborate earlier findings about typical and expected settlers, thereby supporting the hypothesis that in at least temperate wetlands the resulting species assembly is due to deterministic processes (Ruhi et al, 2012a).…”

a b s t r a c tA manmade stormwater wetland in Kalmar, SE Sweden, sized 1 ha and receiving water from residential and road areas, was monitored over the first years after inundation with respect to chemistry and biology. Water flow and chemistry was analysed in years 2-4, mainly on a monthly basis, but, in the final year, every second month. This revealed that total nitrogen, according to the Swedish Environmental Quality Criteria (EQC), typically showed moderate or high concentrations, whereas total phosphorous levels were very high or extremely high. Metal (Cd, Cr, Cu, Pb and Zn) concentrations were low or moderate in terms of EQC. Yearly average reduction of nitrogen was 173 kg ha −1 y −1 , tending to increase over time, and for phosphorous 12.1 kg ha −1 y −1 , tending to decrease. Vegetation analysis was performed in years 1-4 by noting all species in 27 consecutive zones around the wetland system. This showed that one year after filling with water, the vegetation was already well established with >30 plant species in the entire pond system, and this increased only slightly. After four years, the shoreline vegetation cover had become denser, especially with larger graminoids such as common reed (Phragmites australis) and sea club-rush (Bolboschoenus maritimus), and submersed vegetation almost disappeared. There was a tendency for common species to become more dominant, and for less common species to become rarer. Using sweep net sampling of benthic invertebrates during years 0-2, ca 50 species/higher taxa were observed during the first year, largely because of the appearance of many beetles, especially dytiscids. However, these decreased the following years. Apart from these animals, in the first few months the invertebrate colonisation was dominated by chironomids and corixids, whereas later prominent increases were noticed for the isopod Asellus aquaticus, the snail Physa fontinalis, and the mayfly nymph Cloeon dipterum. The results are discussed in terms of wetland values for biodiversity and nutrient reduction, suggesting that these objectives seem possible to combine in stormwater wetlands.

“…Seasonal succession of faunal communities of ponds (Boix et al 2004;Bazzanti et al 2009;Ruhí et al 2012) together with fluctuating hydroperiods (Brooks and Hayashi 2002) can contribute to high biodiversity. Dry periods are followed by rapid colonisation from drought resistant life stages (Aguilar-Alberola and MesquitaJoanes 2011), transport by animal vectors or active immigration (Bilton et al 2001) and seasonal changes in species richness were marked in our data set.…”

“…These water bodies may be permanent or temporary and their importance in contributing to aquatic biodiversity has been recognised in 2 detailed reviews (Wiggins et al 1980;Williams 2006). The majority of studies have concerned temporary ponds particularly in relation to biodiversity and permanence (Schwartz and Jenkins 2000;Boix et al 2001;Nicolet et al 2004;Sanderson et al 2005;Porst and Irvine 2009;Vanschoenwinkel et al 2009;Wissinger et al 2004;Ruhí et al 2012), and the need to protect and conserve these environments has been a central research issue for the European Pond Conservation Network (EPCN http://campus.hesge.ch/epcn/publications.asp [18 May 2011]).…”

Tyre track pools and puddles – Anthropogenic contributors to aquatic biodiversity

2012

a b s t r a c tTwelve sites of tyre track pools and puddles situated in woodland, heath and pasture in Dorset UK were examined to determine their macroinvertebrate species richness and community changes over the course of one year.174 taxa were found with Diptera (59) and Coleoptera (48) contributing 61% of the total. The most frequently occurring and ubiquitous groups were nematoceran dipterans, Oligochaeta, Coleoptera, Crustacea and Lamellibranchiata.Species richness varied with season and on average was highest in March and November samples. On average only 26% (range 16-40%) of the combined total number of taxa found in spring (March) and autumn (November) samples from a site were also found there in each of these seasons individually, indicating a high species turnover through the year.The tyre track pools contributed to local aquatic biodiversity by adding 29 taxa to previously published taxa lists from aquatic habitats in the area. The relative richness of the tyre track pools is attributed to their successional variation in a heterogeneous landscape.Conservation value of 9 of the 12 sites was rated Very high to High and nine regionally notable or rare taxa were recorded. It is suggested that the important conservation status of the tyre track pools warrants greater recognition and further intensive study.

“…Immediately after (if dispersal is high), dispersers arrive from other habitats and may settle successfully depending on their interaction with local abiotic (habitat characteristics including hatching cues for dispersing eggs) and biotic factors (competition, predation and parasitism (Caley and Schluter 1997;Shurin and Allen 2001;Cottenie and De Meester 2004). Over time, recolonization after inundation generally increases taxon richness (Boix et al 2004) until the number of species in the pond resembles the regional species pool or until the strength of local biotic interactions results in decreased establishment success for immigrants Ruhí et al 2012).…”

Re-establishment of zooplankton communities in temporary ponds after autumn flooding: Does restoration age matter?

a b s t r a c tIn temporary ponds, reestablishment of zooplankton communities depends on recruitment from the egg bank, the arrival of dispersers from within the region, and on successful establishment of newly arrived species following interaction with local abiotic and biotic factors. When the ponds dry up, zooplankton species may survive as dormant eggs, and since not all eggs hatch in the next season, eggs will accumulate in the sediment over time, representing an archive of the pond's historical biodiversity.To study the effect of "restoration age" (the time since a water body was restored), we studied groups of ponds that were restored in different years (1998, 2003 and 2007). The restoration process involved extensive dredging of sediments which were used to bury the ponds in the 1960s. Our expectation was that the oldest ponds would have the richest zooplankton community, as they have been accumulating biodiversity over a longer time period. We took weekly quantitative samples of zooplankton during four consecutive weeks after flooding to compare taxon richness and zooplankton community composition between ponds of different restoration age during an early stage of zooplankton community re-establishment.Taxon richness was high and similar to regional levels in all the ponds under investigation, suggesting restoration success and unlimited dispersal. Although cumulative richness at the end of the period was not significantly different between ponds, we observed temporal changes within the study period and certain age-related trends in relation to differences in zooplankton composition. These results suggest a difference in the succession of zooplankton communities depending on restoration age (which could be due to historical or local factors) and that this effect becomes evident from the beginning of the pond hydroperiod.
