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

A study finds for the first time that as levels of aridity increase due to climate change, abrupt changes are experienced on dryland ecosystems.
Disappearing snakes and the biodiversity crisis

Hydropower dams cool rivers in the Mekong River...
on February 14, 2020 at 6:44 pm
Hydropower dams, which use flowing water to turn a series of turbines to generate electricity, provide a source of energy that doesn't rely on fossil fuels. But they also disrupt the flow of rivers, and impact the fish and people that live there.
Climate change will lead to abrupt shifts in...

Drylands cover about 41% of the Earth's land surface and host one in three humans inhabiting our planet. In these areas, life is highly influenced by aridity, i.e. the balance between the amount of rainwater and the water lost by evaporation. In this sense, aridity is increasing worldwide as a result of climate change. A study conducted by the Dryland Ecology and Global Change Lab at the University of Alicante (UA) led by Fernando T. Maestre and published in Science revealed for the first time […]
