Surveys invertebrate phyla, emphasizing evolutionary adaptations and morphological/physiological insights; reorganized text; includes bibliographies
This volume focuses on how environmental pollutants—such as pesticides and industrial chemicals—affect animal behavior and subsequently ecological fitness. It uses experimental methods from behavioural psychology, pharmacology, and neurotoxicology to detect and characterize behavioural changes in both aquatic and terrestrial organisms. These changes are interpreted ecologically at individua…
This authoritative handbook examines the biology, pest status, and control of aphids on key global crops.
