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

    on September 25, 2020 at 3:34 pm

    The largest-ever study of tree rings from Norilsk in the Russian Arctic has shown that the direct and indirect effects of industrial pollution in the region and beyond are far worse than previously thought.

  • Marine heatwaves are human-made
    on September 25, 2020 at 3:33 pm

    Heatwaves in the world's oceans have become over 20 times more frequent due to human influence. This is what researchers are now able to demonstrate. Marine heatwaves destroy ecosystems and damage fisheries.

    on September 25, 2020 at 3:33 pm

    Researchers have found that marine bacteria exploit resource patches efficiently by switching between attached and planktonic lifestyles, and fine-tuning the time spent on patches depending on their quality. Bacteria stayed longer on higher-quality patches, as predicted by patch use theory. Future studies in this area could help to predict the role of marine bacteria in the global carbon cycle.

    New research found that while the increased wildfire activity is causing widespread changes in the structure and composition of these mid-to-high elevation forests, the new landscapes are also likely more resilient to projected upward trends in future fire activity and climate conditions.

    on September 24, 2020 at 3:41 pm

    Researchers have identified a new type of 'landfalling drought' that originates over the ocean before traveling onto land, and which can cause larger, drier conditions than other droughts.

  • A watershed study for wetland restoration
    on September 25, 2020 at 12:08 pm

    Where rivers meet oceans, each cycle of the tide moves water in and out of estuaries. The mixing and mingling of fresh and briny water, combined with seasonal weather, creates a unique environment for ecosystems in coastal estuaries and upstream tidal rivers.

    on September 24, 2020 at 4:43 pm

    Tropical islands have an important ally when it comes to battling storms and sea-level rise: seagrass. During hurricane Irma, an extremely powerful Category 5 storm that hit the North Caribbean in 2017, NIOZ scientist Rebecca James witnessed how native seagrass meadows along the coast of Sint Maarten held their ground, reduced coastal erosion and lowered the chances of flooding. In the years of research during her Ph.D., she saw the pressures on this natural storm protection increasing. In her […]

    Meteorologists track hurricanes over the oceans, forecasting where and when landfall might occur so residents can prepare for disaster before it strikes. What if they could do the same thing for droughts?
