Tr. J. of Zoology 23 (1999) 211-214 © TÜBİTAK A Taxonomical Study on The Rotifera Fauna of Abant Lake (Bolu) Ahmet ALTINDAĞ Department of Biology, Faculty of Science, University of Ankara-TURKEY Received: 21.10.1998 Abstract: The rotifera fauna of Abant lake was studied taxonomically from January to November 1997. A total of 22 rotifer species were identified. Of these, 18 are new for Abant lake and 4 are new for Turkey. Key Words: Rotifera, Abant Lake, Taxonomy, Fauna Abant Gölü’nün (Bolu) Rotifera Faunası Üzerine Taksonomik Bir Çalışma Özet: Ocak 1997-Kasım 1997 tarihleri arasında yapılan bu çalışmada, Abant gölü rotifera faunası taksonomik olarak incelenmiştir. Bu çalışmada 22 rotifer türü tesbit edilmiş olup, bu türlerin 18’si Abant gölü ve 4’ü Türkiye için yeni kayıttır. Anahtar Sözcükler: Rotifera, Abant Gölü, Taksonomi, Fauna. Introduction Four different species of Rotifera are reported for the Phytoplanktons and zooplanktons are the first and first time in Turkish fauna by the present study. second steps, respectively, in the food chain of lake Study area ecosystems. Zooplanktons in the lake ecosystems are Lake Abant, located 30 km south-west of Bolu, food for invertebrates, fish, and some birds. Turkey (40˚37’O” N/31˚15”O” E), was formed by an Copepods, cladocerans and the Rotifers are the main obstruction of rock debris blocking the valley at its groups of zooplanktons. It has been indicated by some location, at an elevation of 920 m from sea level, with a researchers that certain species of phylum Rotifera have surface area of 45 km2 and maximum depth of 40 m indicator characteristics showing water quality, pollution (Figure 1) within the Notrh Anatolian earthquake zone, and eutrophication (1, 2, 3). -
Development and Application of a Landscape-Based Lake Typology for the Muskoka River Watershed, Ontario, Canada
Development and application of a landscape-based lake typology for the Muskoka River Watershed, Ontario, Canada by Rachel Anne Plewes A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Master of Science in Geography Carleton University Ottawa, Ontario © 2015, Rachel Anne Plewes ABSTRACT Lake management typologies have been used successfully in many parts of Europe, but their use in Canada has been limited. In this study, a lake typology was developed for 650 lakes within the Muskoka River Watershed (MRW), Ontario, Canada, to quantify freshwater, terrestrial, and human landscape influences on water quality (Ca, pH, TP and DOC). Five distinct lake types were identified, using a hierarchical system based on three broad physiographic regions within the MRW, and lake and catchment morphometrics derived through digital terrain analysis. The three regions exhibited significantly different DOC concentrations (F=15.85; p<0.001), whereas the lake types had significantly different TP concentrations (F=12.88, p<0.001). Type-specific reference conditions were used to identify lakes affected by human activities that may be in need of restoration due to high TP concentrations. Overall, this thesis demonstrates the applicability of new and emerging landscape modelling tools for lake classification and management in Ontario, Canada. ii ACKNOWLEDGMENTS Firstly, I would like to thank my supervisor Dr. Murray C. Richardson for his guidance and support throughout the past 2 years. Additionally, I appreciate all of Dr. Derek Mueller’s feedback on the drafts of this thesis. I am grateful for the guidance I received from Dr. -

Shifts in the Physical and Biological Characteristics of Alpine Lakes Along an Elevation Gradient in the Rocky Mountains, USA
Aquatic Sciences (2020) 82:11 https://doi.org/10.1007/s00027-019-0684-6 Aquatic Sciences RESEARCH ARTICLE The life aquatic in high relief: shifts in the physical and biological characteristics of alpine lakes along an elevation gradient in the Rocky Mountains, USA Kelly A. Loria1 · Diane McKnight2 · Dillon M. Ragar3 · Pieter T. J. Johnson4 Received: 26 March 2019 / Accepted: 28 November 2019 / Published online: 4 December 2019 © Springer Nature Switzerland AG 2019 Abstract Rapidly occurring environmental changes in alpine lakes highlight the importance of better understanding the ecological structure and function associated with these systems. Previous research has identifed how the physical characteristics of lakes change as a function of landscape position, but comparatively little is known about shifts in the biotic community across mountain regions. In 2016, we sampled 19 lakes across an elevation gradient (2480–3550 m a.s.l.) within the Rocky Moun- tains, USA, to evaluate how both the abiotic characteristics of lakes and their planktonic biological communities covaried with elevation. Based on generalized linear mixed models (GLMMs), increases in elevation were associated with decreases in most nutrient concentrations (with the exception of nitrate), dissolved organic carbon, water temperature and lake stratifcation. Conversely, elevation increases were positively related to nitrate concentrations and water clarity. Extending this analysis to the biological community, we found that higher-elevation lakes exhibited lower phytoplankton and zooplankton densities, whereas elevation associated positively with average zooplankton size. Our data are consistent with the hypothesis that the alpine environment acts as a strong niche flter, limiting the quantity and diversity of taxa to groups capable of tolerating the short growing season, high fushing rate, strong variation in interannual precipitation, intense ultraviolet radiation exposure, and lower resource availability associated with such habitats. -

Project Summary Overview
Project Summary Overview: Lakes, the iconic landscape feature of glaciated landscapes around the world, are important in hydrological and biogeochemical processes, ecological interactions, and ecosystem services. The overarching research question for the North Temperate Lakes (NTL) Long-Term Ecological Research Program is: How do biophysical setting, climate, and land use and cover interact to shape lake dynamics and organization in the past, present and future? Research activities are organized around four interrelated thematic questions: A. Perception of Long-Term Change: How and why have the lake districts changed, and how will they change in the future? B. Climate as a Driver of Long-Term Change: What are the mechanisms of physical and ecological responses of lakes to a changing climate? C. Dynamics of Heterogeneity: What are the long-term patterns, causes, and consequences of spatial heterogeneity in lakes and landscapes? D. Shocks, Shifts and Compensatory Responses: How and when do extreme events and multiple drivers cause ecosystem transitions? Questions will be addressed through research in two regions in Wisconsin, the Northern Highland and Yahara Lake Districts. Physical, chemical, biological, and social patterns and interactions will be examined using a nested set of spatial scales from individual lakes and watersheds, to hydrologically- linked sets of lakes, entire lake districts, multiple lake districts within the Great Lakes region, and comparative studies of lakes and lake districts around the globe. Temporally, scales range from minutes to centuries. Research approaches include acquisition, generation, and analysis of long term observations; comparative studies; experiments; and diverse modeling and statistical tools. The interdisciplinary team includes expertise in biogeochemistry, climatology, demography, ecology (landscape, ecosystem, community, population, and paleo- ecology), economics, education and outreach, hydrodynamics, hydrology, information management, and microbiology.
