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

Microbes can grow on nitric oxide
on March 18, 2019 at 12:41 pm
Nitric oxide (NO) is a central molecule of the global nitrogen cycle. A study reveals that microorganisms can grow on NO. Their results change our view of the earth's nitrogen cycle and how microorganisms regulate the release of greenhouse gases from natural and human-made environments. […]
Nitrogen pollution's path to streams weaves...
on March 15, 2019 at 8:10 pm
Scientists have completed one of the largest and longest examinations to trace unprocessed nitrate movement in forests. The team found that some nitrate occasionally moves too fast for biological uptake, resulting in 'unprocessed' nitrate bypassing the otherwise effective filter of forest biology. […]
Using Thoreau, scientists measure the impact of...
on March 14, 2019 at 11:26 pm
A new study is using observations made by Henry David Thoreau -- 19th-century American naturalist, social reformer, and philosopher -- to explore the effects of climate change on tree leaf-out and, as a result, the emergence of spring wildflowers. […]
Ocean sink for human-made carbon dioxide measured
on March 14, 2019 at 7:16 pm
Scientists have determined the amount of human-made carbon dioxide emissions taken up by the ocean between 1994 and 2007. […]
Researchers uncover new clues to surviving...
on March 14, 2019 at 7:16 pm
'Great Dying' extinction survivors appear to have shared many of the same ecological roles as their predecessors, with one catch -- there was a surge in the number of individuals with more modern traits. These hardy stand-outs did a better job of driving recovery, making ongoing ecological interactions more intense. Insights into this ancient marine system and its occupants can help guide modern conservation in identifying Earth's most resilient species in the face of environmental stress. […]

Microbes can grow on nitric oxide
on March 18, 2019 at 11:34 am
Nitric oxide is a fascinating and versatile molecule, important for all living things as well as our environment. It is highly reactive and toxic; it is used as a signaling molecule; it depletes the ozone layer in our planet's atmosphere; and it is the precursor of the greenhouse gas nitrous oxide (N2O). Nitrogen oxides are also pollutants discharged with exhaust gases, for example from combustion engines in cars, and are harmful to human health. […]

Global warming and acidifying oceans are creating an intense competition between coral and algae that both are set to lose. […]
Nations agree 'significant' plastic cuts

Nations on Friday committed to "significantly reduce" single-use plastics over the next decade, in a series of voluntary pledges that green groups warned fell short of tackling Earth's pollution crisis. […]

Study proves importance of bird poo in enhancing...
on March 15, 2019 at 1:23 pm
A University of Otago study has shown the positive impact bird poo, or guano, has on coral growth in tropical seas. Published online in the respected scientific journal Scientific Reports, the study Seabird nutrients are assimilated by corals and enhance coral growth rates demonstrates that seabird nutrients can significantly boost coral growth rates, offering a positive news story in a decade that has documented dramatic declines in reef health and percentage cover.
