World Migratory Bird Day. World Migratory Bird Day (WMBD) was initiated in 2006 and is an annual awareness-raising campaign highlighting the need for the protection of migratory birds and their habitats. On the second weekend each May, people around the world take action and organize public events such as bird festivals, education programmes and birdwatching excursions to celebrate WMBD. Migratory birds connect all corners and almost every environment of the world along their migration paths.
WMBD is a global event and also hopes to connect the world, and bring together organizations, governments and dedicated people to protect migratory birds for future generations. WMBD works as a network to increase public knowledge about migratory birds and their importance and also connects groups of people to share, celebrate with and learn from each other. 2013 WMBD FLYER: english | français | español | [ additional languages ]
Antarctic Climate & Ecosystems. Antarctica and the South ern Ocean influence both the regional and global climate in profound ways. These vast areas will experience significant change as the world warms, and in turn those changes will impact on the global climate. Many of the impacts of climate change will be seen in the Southern Ocean and Antarctica before anywhere else on Earth. It is ACE’s role to investigate the critical scientific uncertainties that limit the way Australia and the global community can respond to the impacts of these changes. View: Dr Tony Press (CEO) discusses his vision for ACE research View: Dr Steve Rintoul discusses the importance of Antarctic and Southern Ocean regions to Australia's climate We are answering the following five crucial questions. How is the Southern Ocean changing and what are the implications of this change for Australia and global climate? How will the Antarctic ice sheet respond to changes in climate and what impact will this have on our climate and sea level?

Orcas are toothed whales that hunt large single prey items, such as penguins and seals. The Circle of Life Antarctic seas are extremely productive because phytoplankton grows abundantly during the extended daylight of summer and feeds huge populations of krill.

An Abundance of LifeMuch of the ocean around Antarctica is ice-covered for half the year, and the temperature is near freezing all year.
In spring, the sea ice melts, releasing the trapped algae into the water. Antarctic Food Web. EnviroNorth - Home. Walking on Country With Spirits. Located on the eastern shore of Australia’s tropical north, Shipton’s Flat is home to Marilyn, a Kuku Nyungkal Aboriginal woman, and her family. She has been living here the ancestral way — far removed from the services and conveniences of modern life. Like her ancestors before her, Marilyn walks through the Nyungkal bubu, the Nyungkal’s country, acknowledging and conversing with the spirit beings around her.
She greets the spirit of the flowing stream that provides her family with freshwater, the spirits of her mother, father and grandparents that cared for the country before her, the spirits of her ancestors that have been formed into rocks, and the spirits of the trees and animal life around her that lend shade and sustenance. A change in the weather Marilyn has observed that the seasons are getting hotter. Marilyn feels that the “country is transforming, food is disappearing. If animals continue to move further up the mountain, they will disappear into the sky.” What does it mean? Links. Parks and Wildlife Commission NT.

NT Biodiversity Portal. Terrestrial biome. Introduction Many places on Earth share similar climatic conditions despite being found in geographically different areas. As a result of natural selection, comparable ecosystems have developed in these separated areas. Scientists call these major ecosystem types biomes.
The geographical distribution (and productivity) of the various biomes is controlled primarily by the climatic variables precipitation and temperature. The maps in Figures 1 and 2 describe the geographical locations of the thirteen major terrestrial biomes of the world. Because of their scale, these maps ignore the many community variations that are present within each biome category. Most of the classified biomes are identified by the dominant plants found in their communities. The diversity of animal life and subdominant plant forms characteristic of each biome is generally controlled by abiotic environmental conditions and the productivity of the dominant vegetation. Tundra Boreal Forests/Taiga Citation. Primary production.
Global oceanic and terrestrial photoautotroph abundance, from September 1997 to August 2000. As an estimate of autotroph biomass, it is only a rough indicator of primary production potential, and not an actual estimate of it. Provided by the SeaWiFS Project, NASA/Goddard Space Flight Center and ORBIMAGE. The maps above show Earth's monthly net primary productivity from February 2000 to December 2013.
The data come from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. Values range from near 0 grams of carbon per square meter per day (tan) to 6.5 grams per square meter per day (dark green). A negative value means decomposition or respiration overpowered carbon absorption; more carbon was released to the atmosphere than the plants took in. In mid-latitudes, productivity is obviously tied to seasonal change, with productivity peaking in each hemisphere’s summer.

Ecologically sensitive 'hotspots' include regions in the Himalayas and the Tibetan Plateau, eastern equatorial Africa, the Mediterranean region, and Madagascar, where this flame tree grows. Credit: Veer Images PASADENA: By 2100, global climate change will modify plant communities covering almost half of Earth’s land surface. Climate change will also drive the conversion of nearly 40% of land-based ecosystems from one major ecological community type – such as forest, grassland or tundra – toward another, according to a new NASA and university computer modelling study.
“For more than 25 years, scientists have warned of the dangers of human-induced climate change,” said Jon Bergengren, a scientist who led the study while a postdoctoral scholar at the California Institute of Technology in the U.S.. “Our study introduces a new view of climate change, exploring the ecological implications of a few degrees of global warming. Climate change causes relocations Blocking successful migrations.
Citizen Science | Atlas of Living Australia. What is ‘citizen science’? The OpenScientist website offers this definition of citizen science: ‘The systematic collection and analysis of data; development of technology; testing of natural phenomena; and the dissemination of these activities by researchers on a primarily avocational basis.’ Role of citizen science in the Atlas For the Atlas, citizen science is a very important source of data about biodiversity. Data and insights gained through the efforts of citizen scientists can be as valuable as that obtained by scientists working in academia, natural history collections, government agencies and business.
Harnessing the efforts of the thousands of people participating in citizen science will enhance the range and depth of data available in the Atlas. Getting involved in citizen science There are a number of ways in which you can get involved in citizen science, including: Climate Change and Citizen Science. Climate LiteracyAbout Teaching Climate Literacy Environmental observations are the foundation for understanding the climate system.
From the bottom of the ocean to the surface of the Sun, instruments on weather stations, buoys, satellites, and other platforms collect climate data. To learn about past climates, scientists use natural records, such as tree rings, ice cores, and sedimentary layers. Historical observations, such as native knowledge and personal journals, also document past climate change.
