EarthTrends: Information Portal

A subsite of the World Resource Institute, the pages of EarthTrends contains substantial information on various ecosystems, climate and population data, energy, agriculture and biodiversity.

Introduction to Biogeography and Ecology

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

Bright Edges of the World

An electronic exhibit about the world's drylands: what they are and their importance to the lives of people everywhere.

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.

On-line Expeditions

The University of Delaware hosts this site which contains articles and information on a range of exploratory deep sea diving missions, conducted by the scientists of that institution.

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.

Remote Sensing and Monitoring

This site looks at how and why using satellites images are important in detecting changes in land conditions over time.

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.

Population Growth and Balance

An online lesson on population ecology based around the mathematical models of several population types.

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.

Quantitative Population Ecology

On line lectures from Virginia Tech. This website looks at what population ecology is, estimating populations size and density, statistical analysis of population dynamics, exponential and logistic growth, life tables, and more.

Sirtrack - tracking and telemetry for wildlife Research

Covers some of the technology for radiotracking of wildlife. Gives a good idea of the sort of technology available for obtaining data from live populations.

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.

Human Alteration of the Global Nitrogen Cycle

The nitrogen cycle and the impact human activity has had on the global nitrogen cycle, its causes and the consequences.

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.
