ecosystem : the complex of a community of organisms and its environment functioning as an ecological unit — Webster

Encyclopedia

Ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems can be studied in two different ways. They can be thought of as interdependent collections of plants and animals, or as structured systems and communities governed by general rules. The living (biotic) and non-living (abiotic) components interact through nutrient cycles and energy flows. Ecosystems include interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but each ecosystem has a specific, limited space. — Wikipedia

Types of Environmental Ecosystems (Amy Harris, Sciencing)

Biome is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. “Biome” is a broader term than “habitat”; any biome can comprise a variety of habitats.

A ‘biota’ is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. — Wikipedia

Science

Ecology is the branch of biology which studies the interactions among organisms and their environment. Objects of study include interactions of organisms with each other and with abiotic components of their environment. Topics of interest include the biodiversity, distribution, biomass, and populations of organisms, as well as cooperation and competition within and between species. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits. — Wikipedia

  • Plankton head polewards
    on October 15, 2021 at 10:42 pm

    Ocean warming caused by anthropogenic greenhouse gas emissions will prompt many species of marine plankton to seek out new habitats, in some cases as a matter of survival. Researchers expect many organisms to head to the poles and form new communities -- with unforeseeable consequences for marine food webs.

  • Scientists discover large rift in the Arctic’s...
    on October 14, 2021 at 5:11 pm

    In May 2020, a hole a little smaller than the state of Rhode Island opened up for two weeks in the Last Ice Area, a million-square-kilometer patch of sea ice north of Greenland and Ellesmere Island that's expected to be the last refuge of ice in a rapidly warming Arctic. The polynya is the first one that has been identified in this part of the Last Ice Area.

  • Underwater gardens boost coral diversity to stave...
    on October 13, 2021 at 7:22 pm

    Researchers are building symbiotic 'underwater gardens' in the Pacific Ocean to show how different species of coral can work together to possibly restore degraded reefs.

    on October 13, 2021 at 7:21 pm

    Without pollinators, a third of flowering plant species would produce no seeds and half would suffer an 80% or more reduction in fertility. Therefore, even though auto-fertility is common, it by no means fully compensates for reductions in pollination service in most plant species.

    on October 13, 2021 at 2:46 pm

    Illegal or unsustainable wildlife trade affects biodiversity, ecosystem services, people's livelihood, and economies all over the world. Worldwide experts warn about the perils related to this activity and provide a roadmap for curbing its growth.

    on October 8, 2021 at 7:44 pm

    Since the 1970s, dams have been removed from the U.S. at an increasing rate, with the aim to improve the ecology of river ecosystems, fish migration pathways, water quality, and recreation spaces.

    on October 7, 2021 at 6:00 pm

    We regularly hear warnings that climate change may lead to 'tipping points': irreversible situations where savanna can quickly change into desert, or the warm gulf stream current can simply stop flowing. These cautions often refer to spatial patterns as early-warning signals of tipping points. An international team of ecologists and mathematicians has studied these patterns and come to a surprising conclusion. "Yes, we need to do everything we can to stop climate change," the authors said in […]

  • Vultures prefer roosting near civilization
    on October 7, 2021 at 4:52 pm

    Human-altered landscapes often bring hardships for wildlife—unless you're a vulture, according to a new study by University of Georgia researchers.

    Standing on a boat bobbing gently in the Red Sea, Egyptian diving instructor Mohamed Abdelaziz looks on as tourists snorkel amid the brilliantly coloured corals, a natural wonder now under threat from climate change.

    Just weeks before the crucial COP26 climate conference, another global UN summit—this one tasked with reversing the destruction of nature—officially kicks off next week in Kunming, China.
