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

  • Exploring fish flow from fisheries to supper
    on January 21, 2022 at 11:00 pm

    Recent breakthroughs in multiple fields of study now allow researchers to follow the entire life cycle of ocean fishes—from when and where they are spawned, to where they disperse and grow, to when and where they are captured, transported, and eaten.

  • Balanced diet can mitigate negative impact of...
    on January 21, 2022 at 3:29 pm

    Bumblebees are important pollinators because they pollinate many different plant species and are extremely resilient. They can still manage to fly at temperatures that are too cold for other pollinators. Like many other insects, they are in sharp decline. This makes it even more important to find out what bumblebees need to reproduce successfully. A team from the University of Göttingen has shown that a diverse landscape and a diverse pollen diet, which the bumblebees collect as a protein […]

  • Shift work helps marine microbes share scarce...
    on January 21, 2022 at 3:14 pm

    Though they may be small, microorganisms are the most abundant form of life in the ocean. Marine microbes are responsible for making roughly half of the organic carbon that's usable by life. Many marine microbes live near the surface, depending on energy from the sun for photosynthesis.

  • Scientists recommend system of checkpoints to...
    on January 20, 2022 at 8:42 pm

    Research into engineering techniques that might one day be employed to artificially cool the planet poses some of the thorniest questions facing society today. For climate scientists, that tension is compounded by the lack of a broadly accepted oversight framework to guide their research.

  • Scientists trace the path of radioactive cesium...
    on January 20, 2022 at 3:27 pm

    In 2011, the nuclear accident at Fukushima, Japan, resulted in the deposit of radioactive cesium (radiocesium) into habitats in the vicinity. A decade after the accident, researchers from the National Institute of Environmental Studies, Japan, have collated the complicated dynamics of radiocesium within forest-stream ecosystems. Understanding radiocesium flow in the environment could help mitigate contamination and inform future containment strategies.

    on January 25, 2022 at 10:32 pm

    Southern Ontario wetlands provide $4.2 billion worth of sediment filtration and phosphorus removal services each year, keeping our drinking water sources clean and helping to mitigate harmful and nuisance algal blooms in our lakes and rivers.

  • Ocean microplastic pollution may be greater than...
    on January 25, 2022 at 2:30 pm

    The great diversity of scientific techniques and methods used in the study of marine microplastics pollution limits the current knowledge of this serious environmental problem threatening our ecosystems.

    on January 24, 2022 at 3:39 pm

    Taking into account a variety of trees and green structures in four otherwise similar residential courtyards, a new study evaluates their effects on thermal comfort, biodiversity, carbon storage and social interaction. The authors show that those courtyards with more green structures yield considerably better results than those with fewer, and in their cooling capacity have a significant impact on people's thermal comfort.

    Bumblebees are important pollinators because they pollinate many different plant species and are extremely resilient. They can still manage to fly at temperatures that are too cold for other pollinators. Like many other insects, they are in sharp decline. This makes it even more important to find out what bumblebees need to reproduce successfully. A team has shown that a diverse landscape and a diverse pollen diet, which the bumblebees collect as a protein source to nourish their offspring, […]

  • Just what is a ‘resilient’ forest, anyway?
    on January 20, 2022 at 7:07 pm

    What does a 'resilient' forest look like in California's Sierra Nevada? A lot fewer trees than we're used to, according to a study of frequent-fire forests.
