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

    on May 29, 2020 at 7:07 pm

    A recent study explores the ways parasitism will respond to climate change, providing researchers new insights into disease transmission.

    on May 29, 2020 at 1:31 pm

    Climate change could cause abrupt shifts in the amount of vegetation growing in parts of Great Britain, new research shows.

    on May 28, 2020 at 8:10 pm

    Ongoing environmental changes are transforming forests worldwide, resulting in shorter and younger trees. Researchers found that a range of factors, including rising temperatures and carbon dioxide levels, have caused a dramatic decrease in the age and stature of forests.

  • Smart sponge could clean up oil spills
    on May 28, 2020 at 8:05 pm

    Researchers have developed a highly porous smart sponge that selectively soaks up oil in water. It can absorb more than 30 times its weight and be reused many dozens of times.

    on May 27, 2020 at 7:01 pm

    Researchers have shown that an extinction event 360 million years ago, that killed much of the Earth's plant and freshwater aquatic life, was caused by a brief breakdown of the ozone layer that shields the Earth from damaging ultraviolet (UV) radiation. This is a newly discovered extinction mechanism with profound implications for our warming world today.

    on May 29, 2020 at 4:10 pm

    A key atomic building block for all living organisms and one of the most abundant elements in the galaxy, nitrogen is an essential part of our ecosystem. But for our ecosystem to function, nitrogen-based compounds must cycle through air, water, and soil in a delicate balance among the other organic chemical drivers of life.

    Climate change has contributed to the increase in the number of wildfires across the globe especially in the Arctic where forest fires, along with increased permafrost thaw, can dramatically shift stream chemistry and potentially harm both ecosystems and humans. Researchers at the University of New Hampshire have found that some of the aftereffects of a burn, like decreased carbon and increased nitrogen, can last up to five decades and could have major implications on nearby vital waterways […]

    From starling aberrations to self-turbulent fluids, 'active systems' encompass a wide family of phenomena in which individual objects propel themselves forward, allowing them to display intriguing collective behaviors. On microscopic scales, they are found in groups of living organisms which move around by squirming, and are aligned with Earth's gravitational fields due to their bottom-heavy mass distributions. Through research published in EPJ E, Felix Rühle and Holger Stark at the […]

    on May 28, 2020 at 3:48 pm

    Spatial and temporal differentiations are important features in the study of phenology of ecosystems. Plant phenology studies the lifecycle phases in plants driven by environmental factors, and the study of its long-term patterns and dynamics is important to reveal the responses of vegetation in different regions of China to global changes.
