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

- Ancient Indigenous forest gardens promote a...on April 22, 2021 at 10:19 pm
A new study by historical ecologists finds that Indigenous-managed forests -- cared for as 'forest gardens' -- contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators.

Scientists have provided the first evidence to show that eradicating rats from tropical islands effects not just the biodiversity on the islands, but also the fragile coral seas that surround them.

Drivers of freshwater salt pollution such as de-icers on roads and parking lots, water softeners, and wastewater and industrial discharges further threaten freshwater ecosystem health and human water security.

An expansive project is examining the benefits, and limits, of environmental restoration on developed land after humans are done with it.

New research shows that land use by human societies has reshaped ecology across most of Earth's land for at least 12,000 years. Researchers, from over a dozen institutions around the world, assessed biodiversity in relation to global land use history, revealing that the appropriation, colonization, and intensified use of lands previously managed sustainably is the main cause of the current biodiversity crisis.

- Long-term consequences of carbon dioxide emissionson April 16, 2021 at 2:48 pm
The life of almost all animals in the ocean depends on the availability of oxygen, which is dissolved as a gas in seawater. However, the ocean has been continuously losing oxygen for several decades. In the last 50 years, the loss of oxygen accumulates globally to about 2% of the total inventory (regionally sometimes significantly more). The main reason for this is global warming, which leads to a decrease in the solubility of gases and thus also of oxygen, as well as to a slowdown in the ocean […]
- A rich marine algal ecosystem existed 600 million...on April 16, 2021 at 2:43 pm
The first photosynthetic oxygen-producing organisms on Earth were cyanobacteria. Their evolution dramatically changed the Earth allowing oxygen to accumulate into the atmosphere for the first time and further allowing the evolution of oxygen-utilizing organisms including eukaryotes. Eukaryotes include animals, but also algae, a broad group of photosynthetic oxygen-producing organisms that now dominate photosynthesis in the modern oceans. When, however, did algae begin to occupy marine […]

Dr. Luis Buatois (Ph.D.), a faculty member in the Department of Geological Sciences in USask's College of Arts and Science, is the lead author on a new paper published in the journal Terra Nova. The article, titled "Impact of Permian mass extinctions on continental invertebrate infauna," was co-authored with five researchers from universities in Madrid and Salamanca, Spain.

NASA's Jet Propulsion Laboratory in Southern California is providing the instrument that will enable a nonprofit organization called Carbon Mapper to pinpoint and measure methane and carbon dioxide (CO2) point-sources from space. The data collected by the instrument will help to find super-emitters—the small percentage of individual sources that are responsible for a significant fraction of global emissions of methane and carbon dioxide.

As muddy rainwater surged from Hawaii's steep seaside mountains and inundated residential communities last month, the damage caused by flooding was obvious—houses were destroyed and businesses swamped, landslides covered highways and raging rivers and streams were clogged with debris.
