“…Accordingly, the road construction likely disrupted the natural flow of organic matter and caused hydrological changes in the small catchment possibly resulting in reduced water table and increased relative allocation of autochthonous organic carbon. As suggested by earlier research, R. latens inhabits dystrophic lakes with mossy and shallow littoral environments (Nevalainen, 2008;Luoto et al, 2013;Van Damme & Nevalainen, 2019), which is in accordance with the current Sylvilampi record, since the lake is very shallow with a wide semi-aquatic vegetation rim (Fig. 1c, d) and highly organic sediment ([ 80%, Rantala et al, 2016).…”

“…5f). In agreement, Luoto et al (2013) showed that R. latens is an indicator species for meso-and dystrophic small lakes. When applying a similar modeling approach to modern cladoceran data (NE Lapland), which represented summer epilimnetic communities sampled by sweep net hauls, R. latens showed significant, yet not strong, association with organic sediments (Fig.…”

A long hidden chydorid (Chydoridae, Cladocera) taxon, first found as fossil specimens and recently redefined as Rhynchotalona latens (Sarmaja-Korjonen et al., Hydrobiologia 436: 165-169, 2000) is investigated for its biogeography and ecology. Late Holocene sediment sequence from Lake Sylvilampi, NE Finnish Lapland, and R. latens spatial distribution in relation to limno-climatic attributes in Finland were examined. Principal component analyses of fossil cladoceran communities showed that R. latens is mostly affiliated with Alonella excisa-Alonopsis elongata-Alonella nana species pool. Generalized linear modeling of R. latens responses to limno-climatic variation indicated that it prefers acidic, mesotrophic, humic and shallow lakes with organic sediments in NE Lapland and has a north boreal-subarctic climatic affiliation. At the northern end of its geographical distribution (NE Lapland), it reproduces with abundant gamogenesis under environmental stress. The specialized taxon is a benthic detritivore and scraper and has a Holarctic northern-alpine distribution. It is a glacial relict associated with modern analogs of periglacial aquatic environments, and it occurs in semi-aquatic wetlands, lush lake littorals and clear and cold waters. Examination of chydorids as bioindicators, especially those with restricted niches, allow us to understand biodiversity responses of lake littorals under changing limno-climatic regimes.

“…One of the most important groups of primary consumers in many aquatic ecosystems are the Cladocera, small crustaceans that are key ecological indicators (Luoto et al ., ). As Cladocera leave identifiable remains in lake sediments, they are ideal organisms from which to infer planktonic and littoral microinvertebrate community responses to recent warming at high latitudes.…”

Aim Shifts in the distribution of freshwater algal communities as a result of climate-related limnological changes are well documented; however, impacts on higher trophic levels have received less attention. For example, little is known about how Cladocera (Crustacea, Branchiopoda), often dominant invertebrates and key ecological indicators, have responded to recent warming on broad spatial and temporal scales. Here, we use lake sediment records to test the hypothesis that recent, intensive warming in the western Canadian Arctic has resulted in consistent shifts in the composition of cladoceran assemblages.Location Small, first-order lakes in the Mackenzie Delta region of the western Canadian Arctic.Methods Sediment cores representing the recent past (approximately 150-200 years) were obtained from five lakes spanning a strong climatic gradient. Subfossil remains of Cladocera were identified and enumerated and overall primary production was inferred using spectroscopic techniques. The habitat preferences and feeding strategy of each taxon were compared. Detrended canonical correspondence analysis was used to estimate compositional turnover since 1850, and compared with that of three cladoceran assemblages from Nova Scotia, to place high-latitude changes in context. ResultsCladoceran assemblage changes occurred coincident with the timing of known regional warming and were strongly linked to estimated changes in primary production. In the northern and deepest lakes, an increase in the planktonic, filter-feeding taxon Bosmina spp. coincided with a decrease in the generalist littoral taxa Chydorus cf. brevilabris and Alona circumfimbriata. In the more southern lakes, an increase in macrophyte-associated scrapers Acroperus harpae and Eurycercus spp. occurred concurrently with decreases in generalist taxa. In one lake, an increase in another specialist, an obligate mud-dwelling taxon, was observed.Main conclusions In the western Canadian Arctic, warming has resulted in an increase in cladoceran taxa occupying more specialized feeding and habitat niches. Generalist taxa capable of occupying multiple habitats and employing diverse feeding strategies have been systematically replaced by more specialist species. This response is analogous to what has been inferred for algal communities across the Northern Hemisphere, and represents the first evidence of consistent cladoceran changes to recent climate warming in high-latitude regions.

“…), records of late Holocene ephippia assemblages can potentially be overdriven by human‐induced limnological changes (Nevalainen and Luoto, ). As cladocerans and, in particular, the planktonic taxa have a central position in food webs and may be directly affected by both variation in resources and by predation and competition, inference models using cladocerans are vulnerable to inaccuracies stemming from the effects of other structuring forces (Luoto et al , ). However, the climate influence on chydorid ephippia appears to be much more straightforward than the response of (planktonic) species assemblages.…”

To fully utilize palaeolimnological archives for tracking past environmental changes, methodological advances are necessary. We present a novel method to quantitatively reconstruct past summer air temperatures based on fossil chydorid (Cladocera: Chydoridae) ephippia assemblages. We examined a 76-lake training set from Finland for chydorid ephippia distribution to develop a transfer function for summer air temperatures. Subsequently, we tested its usability in downcore reconstructions by inferring Holocene temperatures from Lake Arapisto in southern Finland. Significant climate-related variation was found in the distribution and abundance of chydorid ephippia in the training set. A transfer function for palaeotemperature reconstructions was developed using the partial least squares technique, which showed favourable performance statistics, enabling the test use of the model in a downcore reconstruction. The ephippia assemblages were responding to the Holocene climate development in the Lake Arapisto core. The ephippium-inferred temperatures correlated closely with the previously available independent palaeoclimate data from Lake Arapisto and from an adjacent lake, although the early Holocene samples had poor modern analogues in the training set. The use of fossil chydorid ephippia in palaeoclimatological reconstructions is a promising tool and it can contribute as a valuable addition for multiproxy assessments of past climate changes.
