Arthropods are invertebrates that constitute over 90% of the animal kingdom,?and their?bio-ecology is?closely?linked with global functioning and survival.
Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods?and?nutrition to human communities, and are?important?indicators of environmental change. Yet the population trends of several arthropods species show them?to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth's?biodiversity.?Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago.?Arthropods are?closely?associated with living and non-living entities?alike, making the?ecosystem?services they provide?crucially important.?In order to be effective, plans?for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for?in situ?and?ex situ?conservation.
This two-volume book focuses?on capturing the essentials of arthropod?inventories, biology, and conservation. Further, it seeks to identify?the mechanisms by which arthropod?populations can be sustained in terrestrial and aquatic ecosystems, and by means of which?certain problematic species be managed without?producing harmful?environmental side-effects.

This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing?the?diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it?describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations.?It addresses the?contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods?from?a holistic?perspective?before?addressing?conservation issues at large. This book?offers?a valuable resource for?all?zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in?the?conservation of biological resources.
