43,944円 The congress "Arsenic in the Environment" offers an international, multi- and interdisciplinary discussion platform for arsenic research aimed at short-term solutions of problems with considerable social impact, rather than only focusing on cutting edge and breakthrough research in physical, chem...

14,923円 This seven-volume series is the most extensive treatise on early life histories of the freshwater fishes of North America. It represents the state-of-the-art in fishery biology and provides a systematic approach to the study of early life histories of all the fishes in this region. Each volume co...

50,577円 Knowledge of the early life stages of fishes is crucial for the effective monitoring and management of fish populations and habitats, and the evaluation of environmental impacts and recovery of endangered species. Unfortunately, the proper identification of targeted species has stunted the develo...

14,592円 This discipline of behavioural ecology has reached a turning point- empirical evidence in behavioural ecology has led to the reformulation of the classic explanatory theories, and new areas of interest have opened up. The study of fish provides an excellent model of the subject, allowing a concis...

37,311円 Does a change, which affects a few biological macro-molecules, some cells, or a few individuals within a population, have any ecological significance that would allow the prediction of deleterious effects at higher levels of biological organization, namely the population, community, and ultimatel...

14,923円 Acknowledging the present inability to determine objectively the status and trends among estuarine ecosystems, the environmental research community has recently stepped up efforts to develop and evaluate meaningful estuarine indicators. This goal requires the effort of researchers from a broad sp...

17,576円 Estuaries in every country exemplify the same paradox- they are among the most productive ecosystems and also among the most impacted by anthropogenic activities. And although estuarine biodiversity is key to the ecological and economic health of coastal regions, estuaries are exposed to toxic ef...

14,923円 Seagrasses are becoming widely used as in situ indicators of the relative health and condition of subtropical and tropical estuarine ecosystems. To permit meaningful management of our estuaries, there is clearly a need to develop and refine ways of effectively monitoring and assessing seagrasses....

14,923円 The evolution of observational instruments, simulation techniques, and computing power has given aquatic scientists a new understanding of biological and physical processes that span temporal and spatial scales. This has created a need for a single volume that addresses concepts of scale in a man...

106,959円 The first half of this book is primarily a systematic survey of the snails, beginning with glossaries, keys for identification to genera and a checklist of species. This is followed by a synopsis of species, with brief notes on ecology, distribution and parasites. Relationships are then described...

43,944円 The large amount of information on fish reproduction available is not always readily accessible to all interested parties. Written to appeal to aquaculturalists, conservation managers, and scientific researchers, Methods in Reproductive Aquaculture provides an overview of available techniques and...

50,577円 The use of environmental assessment procedures within monitoring frameworks demands that there be some relevancy to the decisions that management agencies make using biological criteria. These biological criteria standards are the basis for environmental indicators, which provide a direct measure...
