The paper presents the results of a palaeoecological study of Neolithic archaeological layers from a wetland, multilayer site, Serteya II (Western Russia). It contains, domestic structures, rich organic artefacts, skeletons, and ecofacts preserved within lacustrine deposits that are extremely important on a European scale. We employed a set of specialised palaeoecological analyses and accelerator mass spectrometry radiocarbon dating to identify the principal environmental conditions which attracted Neolithic hunter‐fisher‐gatherer communities from 4300 to 1600 cal. BC. The distinct impact of communities using a nonproductive economy on the ecology of the palaeolake shore zone was recorded. Also, palaeolake water level changes influenced the palaeoeconomic activity of local Neolithic societies, such as gathering of plants (for the medicinal use or serving as dietary components), fishing activities, and possible funeral practices. In addition, the identified phases of high‐water level changes, which were responses to climatic oscillations, were correlated with supraregional climatic events, especially ca. 6.2, 5.9, and 4.2 ka cal. BP. Thus, our results allowed for the reconstruction of environment transformations and conditions of Neolithic communities' activity, as well as for a better understanding of the relationships between local Neolithic communities' way of life and neolithisation processes in Eastern Europe.
Chironomid (Diptera: Chironomidae) larvae play an important role in a wide range of aquatic ecosystems. The study focuses on Chironomidae trophic guilds and morphological types as indicator traits in reconstructions of habitat changes in shallow water bodies. Mentum and ventromental plates are important mouthparts whose shape depends on food type and feeding behavior. Chironomidae larvae strongly vary in the mode of life and feeding habits, representing almost every feeding group. Here we classified the mentum types into 16 groups and tested if they indicated similar past habitat changes as the Chironomidae functional feeding groups (FFGs), and tribes/subfamilies. Paleoecological data of biotic and abiotic proxies were derived from short sequences from a Late Glacial oxbow and a nearby medieval moat located in Central Poland. The study revealed that the habitat substratum structure, vegetation and physicochemical conditions are associated both with the feeding types and morphological traits. This provides a valuable tool for future reconstructions of habitat changes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
