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 ultimately the ecosystem?
With contributions from experts in the field, Ecological
Biomarkers: Indicators of Ecotoxicological Effects explores how
biomarkers can be used to predict effects farther down the chain.
It presents a synthesis of the state of the art in the methodology
of biomarkers and its contribution to ecological risk assessment.
This book describes the core biomarkers currently used in
environmental research concerned with biological monitoring,
biomarkers which correspond to the defences developed by living
organisms in response to contaminants in their environment, and
biomarkers that reveal biological damage resulting from contaminant
stressors. It examines the efficacy of lysosomal biomarkers,
immunotoxicity effects, behavioral disturbances, energy metabolism
impairments, endocrine disruption measures, and genotoxicity as all
indicative of probable toxic effects at higher biological levels.
It is time to revisit the biological responses most ecologically
relevant in the diagnosis of the health status of an aquatic
environment well before it becomes unmanageable. Biomarkers provide
a real possibility of delivering an easily measured marker at a
simple level of biological organization that is predictably linked
to a potentially ecologically significant effect at higher levels
of biological organization. The text explores the latest knowledge
and thinking on how to use biomarkers as tools for the assessment
of environmental health and management.
