Abstrak :
The Biology of Lakes and Ponds focuses on the interactions between the abiotic frame, such as turbulence, temperature, pH and nutrients, and the organisms, including interactions with and among organisms at the individual, population and community level. The book fills this niche between traditional limnology and evolutionary ecology by focusing on physiological, morphological and behavioural adaptations among organisms to abiotic and biotic factors and how interactions between biotic processes and abiotic constraints determine the structure and dynamics of lake and pond systems. In addition, the book describes and analyses the causes and consequences of human activities on freshwater organisms and ecosystems and covers longstanding environmental threats, such as eutrophication and acidification, as well as novel threats, such as biodiversity loss, use of everyday chemicals and global climate change. However, also signs of improvement and the possibilities to restore degraded ecosystems are discussed and provide hope for future generations.

Abstrak :
Kolong adalah badan air berupa danau-danau kecil yang terbentuk akibat galian dari aktivitas penambangan timah di Pulau Bangka. Bentuk secara fisik seperti tidak adanya inlet dan outlet, umur, sumber air, dan jenis mineral dominan dari material geologi area penambangan mempengaruhi kondisi limnologis suatu kolong. Penelitian ini bertujuan untuk melihat karakteristik limnologis beberapa kolong bekas tambang timah. Pengamatan dilakukan terhadap beberapa kolong bekas tambang dengan kondisi lingkungan yang berbeda. Kedalaman kolong dari 3 m sampai dengan 15 m yang paling dalam. Kolong mempunyai kisaran pH (2,8 - 7,3); DO (3,46 - 8,74 mg/L); dan Konduktivitas (0,01 - 6,38 mS/cm). Oksigen terlarut pada air dasar beberapa kolong < 1 mg/L. Kandungan logam pada kolong yang pH airnya < 3 mempunyai kandungan logam seperti Pb, Fe, Al, dan Zn yang tinggi melebihi baku mutu air bersih. Kandungan beberapa parameter lainnya di air kolong seperti sulfat berkisar antara 3 - 2162 mg/L, TN 0,3 - 5.4 mg/L, dan TP 0,02 - 17,25 mg/L. Jenis plankton yang dominan ditemukan di kolong yang mengandung TN/TP tinggi adalah jenis Trachellomonas dan Mycrocystis yang merupakan jenis plankton yang menjadi indikator bahwa suatu perairan telah tercemar senyawa organik. Pengembangan pemanfaatan kolong yang berpotensi harus berdasarkan pada kondisi limnologis uniuk menjaga kesinambungan kualitas air kolong.

Abstrak :
This volume offers a general description of reservoir limnology in tropical and subtropical China. It functions as a window opening to all the aquatic scientists with a main focus on reservoirs in southern China and at the same time also covering several important, large reservoirs such as the Three Gorge Reservoir and Danjiangko Reservoir. Topics discussed are zooplankton, phytoplankton and zoobenthos communities, cyanobateria, nutrient budget, sediments, biogeochemical cycling of mercury, fishery and eutrophication.

Abstrak :
The eleven chapters cover many aspects of the physics, geochemistry and biology of the lake, with a particular focus on the unique physical and geochemical features of the water column and on the ecological functioning of the surface waters. The impacts of the introduced fish species and the potential impacts of methane exploitation are also summarized. This multi-disciplinary book may also be used as an introduction to the limnology and biogeochemistry of large tropical lakes, as it covers various aspects of the physics, geochemistry, biology and ecology of the African Great Rift lakes.​

This book focuses on the long-term interactions between people and nature in and around Lake Biwa, one of the oldest lakes in the world. Accordingly, it not only covers the characteristics of the biota of this ancient lake, but also approaches it as a ‘cultural ancient lake.’ Furthermore, various problems affecting the lake, especially recent environmental changes that occurred before and after Japan’s rapid economic growth of the 1950s and 60s, are reviewed, including water pollution, lakeshore development and the reclamation of attached lakes, alien and invasive species, and problems related to the recent warming of the climate. Lastly, by analyzing data on these problems collected by the local government and residents of the lake basin, the book provides a comprehensive outlook on the future of Lake Biwa and people’s lifestyles.
