“…total richness) requires elaborate sampling campaigns because of the high spatial and temporal variability in zooplankton community composition (Arnott et al 1998;De Meester et al 1999;Grover 1999;Burks et al 2002). The number of sampling occasions can be reduced by identifying hatchlings isolated from lake sediment samples, as suggested by Jeppesen et al (2003) and Brendonck & De Meester (2003). These authors suggest that seasonal and, to a limited extent, year-to-year variation observed in active communities is integrated in the dormant egg bank or as remains of other body parts like carapaces, headshields etc.…”

“…Species lists acquired through hatching of dormant eggs are biased due to the fact that some populations seldom or never form resting eggs (Jeppesen et al 2003) and to the variation among taxa in their response to specific hatching stimuli (Schwartz & Hebert 1987;Carvalho & Wolf 1989;Cáceres 1998). The latter source of bias can be partly ruled out by incubating the eggs under a wide range of hatching conditions (Vandekerkhove et al, in preparation), but this is time consuming and labor-intensive.…”

“…The Palaeolimnological Predation Index (PPI) is based on a relationship between the ephippia ratio of Daphnia/(Daphnia ? Bosmina) and fish abundance (catch per unit effort in gillnets) (Jeppesen et al, 2003). The macrophyte indices are Chydoridae/ (Chydoridae ?…”

“…Changes in the contribution of key cladoceran taxa may therefore yield information about habitat alterations and changes in lake trophic structure (Frey & Pamini, 1986;Jeppesen et al, 2001). In addition, cladoceran subfossils are useful indicators of changes in predation by planktivorous fish and fish stockings (Amsinck et al, 2007), the latter being reflected in changes in the size of Daphnia ephippia (Verschuren & Marnell, 1997;Jeppesen et al, 2002) and the contribution of Daphnia to the total sum of Daphnia and Bosmina ephippia (Leavitt et al, 1994;Jeppesen et al, 2003). Changes in cladoceran community can also be caused by climate change (Smol et al, 2005;Thienpoint et al, 2015) though such effects may be difficult to separate from those of other factors.…”

Ecosystem change in the large and shallow Lake Säkylän Pyhäjärvi, Finland, during the past ~400 years: implications for management

Lake Säkylän Pyhäjärvi has been an important fishing site and drinking water source for the local population for centuries. The lake has undergone significant changes: (1) the water level was lowered in the 1600s and in the 1850s; (2) planktivorous coregonid fish were successfully introduced in the early 1900s; (3) nutrient input from intensified agriculture has increased since the 1950s and (4) the effects of the current variable climate on the lake and its catchment have become more evident since the 1990s. We determined the phases of oligotrophication, eutrophication and recovery and elucidated the ecosystem changes by combining palaeolimnological records with detailed neolimnological data. The sedimentary diatom and cladoceran assemblages first showed a relatively eutrophic period followed by oligotrophic periods, linked with the artificial changes in water level and consequent shifts in macrophyte abundance. The oligotrophic period in the early 1900s is thought to represent the target trophic state for the lake. After the 1950s, introduction of vendace resulted in higher planktivory reflected by an increased relative abundance of small-bodied pelagic cladocerans. Signs of eutrophication occurred due to increased nutrient load. During the last 10 years, signs of recovery have been recorded. A complex history such as that of Lake Pyhäjärvi illustrates the difficulties in selecting management targets, and the risk of setting false targets, for lakes based solely on monitoring data-both neolimnological and palaeolimnological approach are needed.

“…Prior to this quantitative method, cladoceran assemblages and morphology had been used in many studies to identify past changes in fish stocks and predation (Kerfoot, 1974(Kerfoot, , 1981Salo et al, 1989). More recently, Jeppesen et al (2002Jeppesen et al ( , 2003 showed that size and abundance of ephippia of some planktonic cladoceran species are related to fish abundance and can therefore be used as indicators for planktivorous fish stocks. Also, the well-preserved mandibles of Chaoborus (Chaoboridae) larvae have been used to infer changes in past fish populations, since Chaoborus occurs in fish-free lakes or in lakes with refugia (hypolimnion) against fish predation (Uutala, 1990;Sweetman and Smol, 2006;Luoto and Nevalainen, 2009).…”

Key-words:Chaoborus, Chironomidae, Cladocera, community structure, paleolimnology, predationWe investigated surface sediment assemblages of invertebrates from nine shallow lakes in southern Finland and assessed the relationship between invertebrate assemblages and fish status at local scale for the purpose of paleolimnological food-web studies. Invertebrate-based cluster analysis separated the fish-free lakes into their own group and the results also showed a strong and statistically significant relationship between fish status and faunal sedimentary assemblages. The present results from the local data set indicate good potential for developing quantitative invertebrate-based paleolimnological fish status models in the future. However, for the implementation of the models substantially more lakes with different fish status need to be examined that the effect of fish predation on invertebrate communities can be separated from other limnological forcing mechanisms. RÉSUMÉImplications sur l'usage des communautés d'invertébrés sédimentaires pour inférer la présence passée de poisson Mots-clés :Chaoborus, Chironomidae, Cladocera, structure de communauté, paléolimnologie, prédation Nous avons étudié les communautés d'invertébrés du sédiment de surface de neuf lacs peu profonds du sud de la Finlande et établi la relation entre les assemblages d'invertébrés et le statut piscicole à l'échelle locale dans le but d'études paléolimnologiques des réseaux trophiques. L'analyse de classification basée sur les invertébrés a séparé les lacs sans poissons en un groupe isolé et les résultats ont aussi montré une forte et statistiquement significative relation entre le statut piscicole et les assemblages de faune sédimentée. Ces résultats d'un jeu de données locales indiquent un bon potentiel futur pour le développement de modèles quantitatifs du statut piscicole ancien basés sur la paléolimnologie des inverté-brés. Toutefois, l'implémentation des modèles demande bien plus de lacs étudiés de différents statuts piscicoles de façon à ce que l'effet de la prédation sur les communautés d'invertébrés puisse être séparé des autres mécanismes limnologiques de forçage.
