Ecology

Ecology (from Ancient Greek οおみくろんἶκος (oîkos) 'house', and -λογία (-logía) 'study of') is the natural science of the relationships among living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and is the study of abundance, biomass, and distribution of organisms in the context of the environment. It encompasses life processes, interactions, and adaptations; movement of materials and energy through living communities; successional development of ecosystems; cooperation, competition, and predation within and between species; and patterns of biodiversity and its effect on ecosystem processes. Ecology has practical applications in conservation biology, wetland management, natural resource management (agroecology, agriculture, forestry, agroforestry, fisheries, mining, tourism), urban planning (urban ecology), community health, economics, basic and applied science, and human social interaction (human ecology). The word ecology (German: Ökologie) was coined in 1866 by the German scientist Ernst Haeckel. The science of ecology as we know it today began with a group of American botanists in the 1890s. Evolutionary concepts relating to adaptation and natural selection are cornerstones of modern ecological theory. Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living (abiotic) components of their environment. Ecosystem processes, such as primary production, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment. Ecosystems have biophysical feedback mechanisms that moderate processes acting on living (biotic) and abiotic components of the planet. Ecosystems sustain life-supporting functions and provide ecosystem services like biomass production (food, fuel, fiber, and medicine), the regulation of climate, global biogeochemical cycles, water filtration, soil formation, erosion control, flood protection, and many other natural features of scientific, historical, economic, or intrinsic value. (Full article...) Selected article - The Albanian Alps represent a major geomorphological part of Albania. It is the southernmost continuation of the Dinaric Alps, which extend along the Adriatic Sea from the Julian Alps in the northwest down to the Albanian Alps in the southeast. For a small country, Albania is characterised by a considerable wealth of terrestrial and marine ecosystems and habitats with contrasting floral, faunal, and fungal species, defined in an area of 28,748 square kilometres. Most of the country is predominantly of Mediterranean character, comprehending the country's center and south, while the alpine affinity is more visible in the northeast. Apart the diversity of topography and climate, the direct proximity of Albania to the Mediterranean Sea and the significant location within the European continent have created favorable conditions for appearance of a vast array of flora, fauna and funga with an immense quality, which led the country to be recognised as an important biodiversity hotspot in the continent. The number of globally threatened faunal species in Albania is high with an integral part of more than 181 species, ranking seventh in the Mediterranean Basin. (Full article...)

The humpback anglerfish uses a modified dorsal spine as a fishing rod with a bioluminescent lure to attract and capture prey. Aggressive mimicry is a form of mimicry in which predators, parasites, or parasitoids share similar signals, using a harmless model, allowing them to avoid being correctly identified by their prey or host. Zoologists have repeatedly compared this strategy to a wolf in sheep's clothing. In its broadest sense, aggressive mimicry could include various types of exploitation, as when an orchid exploits a male insect by mimicking a sexually receptive female (see pseudocopulation), but will here be restricted to forms of exploitation involving feeding. For example, indigenous Australians who dress up as and imitate kangaroos when hunting would not be considered aggressive mimics, nor would a human angler, though they are undoubtedly practising self-decoration camouflage. Treated separately is molecular mimicry, which shares some similarity; for instance a virus may mimic the molecular properties of its host, allowing it access to its cells. An alternative term, Peckhamian mimicry, has been suggested (after George and Elizabeth Peckham), but it is seldom used. Aggressive mimicry is opposite in principle to defensive mimicry, where the mimic generally benefits from being treated as harmful. The mimic may resemble its own prey, or some other organism which is beneficial or at least not harmful to the prey. The model, i.e. the organism being 'imitated', may experience increased or reduced fitness, or may not be affected at all by the relationship. On the other hand, the signal receiver inevitably suffers from being tricked, as is the case in most mimicry complexes. (Full article...)

Selected quote - “ The environmental movement is one of the most successful social change movements. Popularizing Earth Day celebrations can be credited with bringing the movement to the mainstream. Through grassroots efforts, festivals, fairs, assemblies and concerts have helped popularize concern for our environment in the public's mind. Since so many people participate in Earth Day activities, Earth Day is the perfect opportunity to get people to tap-into the better world movement, so that they can find the inspiration and encouragement to continue activities for a more peaceful, just and sustainable world all year long. ” —Robert Alan, American Writer, Artist, Social Activist Ecology news From the Wikinews Environment portal April 23: European Union to reduce carbon emissions by 55% of 1990 levels by 2030 November 27: Wikinews interviews Craig Farquharson, Liberal Democrat candidate for 2020 Groom by-election November 27: Wikinews interviews Sandra Jephcott, Sustainable Australia candidate for 2020 Groom by-election December 14: Greta Thunberg named 2019 Time Person of the Year November 23: Researchers break down deaths due to power plant pollution in the United States November 21: Slippery business: Materials scientists invent new coating for self-cleaning, water-efficient toilets October 19: Northern Arapaho Tribe welcomes buffalo herd in Wyoming, United States October 12: Scientists describe how 'upside-down rivers' of warm water break Antarctica's ice shelf October 5: Voracious fish defend coral reefs against warming, say scientists September 8: Scientists report skyrocketing phytoplankton population in aftermath of Kīlauea eruption Additional News Highlights November 5, 2009: "New ocean forming in African desert."
