Ecology is defined as the study of inter relationship and interaction
of different organisms with each other and with their environment. It is
concerned with the general principles that apply to both animals and plants.

Ecosystem services as
a concept plays a key role in solving global environmental and human ecological
crises and associated other problems, especially today when the sixth major
extinction event of the history of the biosphere is in progress, and humanity
can easily become a victim of it. The aim of this book is to give an
overview and report from the frontiers of research of this important and
interesting multidisciplinary area.
Chemical ecology has made major progress in recent decades. Topics
covered includes: The Chemistry of Poisons in Amphibian Skin, The Chemistry of
Phyletic Dominance, Chemical Signals in the Marine Environment, Analysis of
Chemical Signals by Nervous Systems, Chemical Ecology.
This note covers the
following topics: Forests and Society, Ecosystem Concept and Forest Ecosystem
Goods, Forest Population Ecology, Forest Community Ecology, Forest Production
Ecology, Forest Nutrition and Biogeochemistry, Forest Silviculture, Forest
Restoration, Forest Restoration and Forest Conservation.
Aim of this book is to bring out a
general view on the function of ecosystems, modelling, sampling strategies,
invading species, the response of organisms to modifications, the carbon
dynamics, the mathematical models and theories that can be applied in diverse
conditions.
This book covers the following topics in plant ecology: Ecology of Roots,
Ecology of Stems, Ecology of Leaves, Symbiosis, Pollination, Reciprocal
Nutritive Disjunctive Symbiosis, Social Conjunctive Symbiosis, Nutritive
Conjunctive Symbiosis, Growth Habits of Plants, Plant Communities, Plant
Succession and Applied Ecology.
This Introductory Ecology
Module explains the hierarchical structure of ecology-species, populations,
communities, and ecosystems. Each lecture will focus on a key ecological
principle then provide applied examples to further demonstrate the concept.
