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

Encyclopædia Britannica

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

  • UN urges ambitious action to protect the oceans
    on July 1, 2022 at 9:41 pm

    World leaders must do more to protect the oceans, a major United Nations conference concluded on Friday, setting its sights on a new treaty to protect the high seas.

  • Wildfire risk has grown nearly everywhere, but we...

    Humans have raised CO₂ levels in the atmosphere to 50% above what they were before the industrial revolution. As a result, the world has already warmed by 1.1°C over the past century and reports indicate that it could reach 2.7°C of warming by the end of this century.

  • Even temporarily overshooting 2°C would cause...
    on June 30, 2022 at 2:26 pm

    The history of climate change is one of people slowly coming to terms with the truth. None but a small minority still question whether it's real and caused by humans. Now most grapple with the reality of trying to slow down catastrophic warming, and the difference between solutions and false hope. The concept of climate overshoot is the next thing we will need to get to grips with.

  • Wildfires may have sparked ecosystem collapse...
    on June 30, 2022 at 8:25 am

    Researchers at University College Cork (UCC) and the Swedish Museum of Natural History examined the end-Permian mass extinction (252 million years ago) that eliminated almost every species on Earth, with entire ecosystems collapsing. The researchers discovered a sharp spike in wildfire activity from this most devastating of mass extinctions. Promoted by rapid greenhouse gas emissions from volcanoes, extreme warming and drying led to wildfires across vast regions that were previously permanently […]

  • Team reassesses greenhouse gas emissions from...
    on June 29, 2022 at 9:02 pm

    The emissions of carbon dioxide (CO2) and methane (CH4)—the most potent greenhouse gases—into the atmosphere from African lakes are reassessed in a study undertaken by the Laboratory of Chemical Oceanography (FOCUS research unit / Faculty of Science). While it was previously assumed that these lakes were significant CO2 sources, it has since been discovered that they really emit very little CO2 but a lot of methane, adding to the emissions burden. The study is published in Science Advances.

    on July 1, 2022 at 8:33 pm

    Recently, a group of 23 science and policy experts from the U.S. and Canada published a review of mining risks to watersheds ranging from Montana to British Columbia and Alaska. The paper brought together experts in salmon ecology, watershed science, mining impacts and mining policy to integrate knowledge across research fields that often work independently from one another.

    on July 1, 2022 at 2:27 pm

    Researchers investigating the exposure of small mammals to plastics in England and Wales have found traces in the feces of more than half of the species examined. The densities of plastic excreted were comparable with those reported in human studies.

    on June 30, 2022 at 3:45 pm

    A study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The affected areas are in Southern, Central and Northern Europe but this historical change in Europe's fire regime is more intense in the Mediterranean area.

    on June 30, 2022 at 3:45 pm

    While there are many studies that discuss antibiotic resistance genes (ARG) in soil and water environments, there is currently very little research that focuses on ARG in aerial environments. In a recent review, researchers have analyzed current research trends regarding ARG in bioaerosols, including their sources, methods of detection, and implications for the future.

    on June 30, 2022 at 3:44 pm

    Researchers examined 21st century changes in ocean-surface temperature, salinity, and density, across mangrove forests worldwide. Their study suggests that changes in surface-ocean density may impact the dispersal patterns of widely distributed mangroves species, and more likely so in the Indo-West Pacific region, the primary hotspot of mangrove diversity.
