General Sites for Ecology

Calculate Your Ecological Footprint
How big is your ecological footprint? Complete the questionnaire to determine your impact on the planet!
Introduction to the Physical Environment
An introduction to many aspects of ecology such as abiotic and biotic factors, species distribution, ecological niche, succession, biomes, food chains, trophic levels, food webs, nutrient cycles.
NatureWorks
An excellent website containing a range of ecological issues including: ecosystems, marine, freshwater and terrestrial communities, population dynamics, plus much more.
eNature
eNature.com provides a wide range of information from a very nicely presented site. Field guides, species lists, expert advice, and ackyard wildlife are some of the options.

Ecosystems

Canada's Aquatic Environments
This Canadian site, allows you to learn more about the various animals and plants in their different environments. Also includes a section on human interactions and current research.
Coral Reef Ecology
This is a part of the Starfish website, showing information on coral reef ecology, marine biology and the many animals which inhabit these areas.
Desert Biome
This site examines different types of deserts, what causes them and contains a list of desert dwelling animals and plants with a brief background description of each.
Freshwater Ecosystems
A brief introduction to freshwater ecosystems.
Intertidal Zones
This page includes information about tide pools, how they are formed and the different areas of the tidal zones.
Mangrove WWW Sites
This site lists a selection of useful websites dealing with mangrove ecosystems.
Marine Sciences
This site provides marine educational links aimed from K-12 level. Learn about various marine ecosystems from mangroves to the deep sea..
Racerocks.com Educational Index
A virtual exploration of a marine ecosystem, where you'll find plenty of activities exploring a wide range of ecological concepts.
Vegetation map checklist
From here you can select your country of interest to obtain current maps showing distributions of different vegetation types.
What is an Ecosystem?
What is a Biome? What is an Ecosystem? How have humans affected the ecosystems? These are some of the questions discussed on this Thinkquest webpage.

Environmental Monitoring

BBC News: Past climate anomalies explained
Unusually warm and cold periods in Earth's pre-industrial climate history are linked to how the oceans responded to temperature changes, say scientists.
Amphibian Monitoring Program
Frogs and other amphibians are vanishing and no one knows why. Take a look at the various monitoring programs under way to determine the decline in frogs and salamanders.
Environmental Protection Agency
An Australian website (Queensland). Explore a range of issues such as monitoring waste, air and water. As well as coastal and wildlife conservation. There are many pdf leaflets available for download.

Populations and Communities

Communities
This website provides lecture notes on communities, includes niche concept, species interactions (mutualism, commensalism, competition, predation, parasitism), community stability and change.
Competition
A look at intra- and interspecific competition used by plants for obtaining water, and for root distribution.
Death Squared
An experiment involving the explosive growth and demise of a mouse population. Starting with four pairs of mice, the population increased with some interesting results.
Gap Dynamics
This website provides information on Gap Dynamics. Gap size, rotation interval, causes and closure are all discussed.
Intraspecific Relations: Cooperation and Competition
A look at Intraspecific interactions, including reproductive strategies, cooperation, competition, and defence mechanisms.
Population Ecology
Part of the Online Biology Book. With the good use of diagrams this website introduces us to what ecology is, population growth and factors influencing population growth.
Ecological Succession
Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing. This series of pages explains ecological succession and gives examples based on British habitats.
Tree Regeneration and Growth in Gaps
There are currently 23 research projects underway at the ICH forest of Date Creek, this is one of them and discusses Tree Regeneration and Growth in Gaps.

Energy Flows and Nutrient Cycles

Energy and Food webs
Food chains and food webs show the flow of energy through an ecosystem. Food chains are linear depictions of energy flow, while food webs show the multiple interactions among the different types of organisms.
Bioaccumulation
Learn about bioaccumulation and the process of bioaccumulation in a typical food chain.
Nitrogen: The Essential Element
This site, part of the Pesticide Management Education Program at Cornell University, deals with the use of nitrogen as a fertiliser and the fate of nitrogen in the environment.
The Carbon Cycle
Part of jkimball's website. Easy to read and with the use of graphic explains the carbon cycle. Also has a table of estimated major stores of carbon on the earth
The Nitrogen Cycle
Part of jkimball's website. This page examines the nitrogen cycle and its interaction with the ecosystem. Also briefly looks at how human activities have altered the nitrogen cycle.
The Water Cycle
Provided by the USGS, this webpage illustrates the Water Cycle and discusses the ideas behind the diagram.
Food Webs and Energy Flow
Part of jkimballs website, this page discusses through detailed writing and diagrams concepts such as Food Webs, Energyflow through food chains, The Pyramid of Energy and more.
