Basic Science

First Ecology: ecological principles and environmental issues provides a critical and evaluative introduction to the science of ecology. Alan Beeby and Anne-Maria Brennan present a succinct survey of ecology, describing and explaining the relationship between living organisms and their environment.

The third edition of this popular book continues to introduce ecology from a human perspective. This view of humanity as part of the ecology of the planet makes the fundamental relevance of ecology to all life science students apparent throughout. First Ecology develops in sequence the core themes in ecology at each level of organisation - subcellular, population, ecosystem, landscape and planetary. Understanding this hierarchy - and the interplay between these levels - is crucial to the environmental decisions our species faces at the start of the twenty-first century. First Ecology is the ideal primer for you to develop this understanding.

Key Features
Specifically devised for first year life science students or students from other disciples taking ecology as a standalone unit: breadth and depth are perfectly balanced for a first course in ecology
Assumes little background knowledge and leads students gradually into the subject to build understanding, making it ideal for students from a range of disciplines
Uses a human angle to introduce ecological concepts in a way students will relate to and engage with, developing students' confidence at each step
Detailed examples and case studies help build on the principles introduced in the text, allowing students to see ecological techniques in action
Case studies in each chapter provide a captivating insight into how ecologists approach problems
All diagrams are presented in full colour, and many new stunning photographs help students to visualise the concepts being described
Expanded coverage of soil; climate change; biodiversity; competition; conservation and sustainability presents a true picture of ecology today
