Ecology

Ecology (from Greek: , "house" and -, "study of") is the study of the relationships between living organisms, including humans, and their physical 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.

Ecology is not synonymous with environmentalism or strictly natural history. Ecology overlaps with the closely related sciences of evolutionary biology, genetics, and ethology. An important focus for ecologists is to improve the understanding of how biodiversity affects ecological function. Ecologists seek to explain:

  • Life processes, interactions, and adaptations
  • The movement of materials and energy through living communities
  • The successional development of ecosystems
  • The abundance and distribution of organisms and biodiversity in the context of the environment.

Ecology has practical applications in conservation biology, wetland management, natural resource management (agroecology, agriculture, forestry, agroforestry, fisheries), city planning (urban ecology), community health, economics, basic and applied science, and human social interaction (human ecology). It is not treated as separate from humans. Organisms (including humans) and resources compose ecosystems which, in turn, maintain biophysical feedback mechanisms that moderate processes acting on living (biotic) and non-living (abiotic) components of the planet. Ecosystems sustain life-supporting functions and produce natural capital 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.

The word "ecology" ("Ökologie") was coined in 1866 by the German scientist Ernst Haeckel. Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics. Ancient Greek philosophers such as Hippocrates and Aristotle laid the foundations of ecology in their studies on natural history. Modern ecology became a much more rigorous science in the late 19th century. Evolutionary concepts relating to adaptation and natural selection became the cornerstones of modern ecological theory.

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 and faunal 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 and fauna with an immense quality, which, however, led the country to be recognised as an important biodiversity hotspot in the continent. The number of globally 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 carbon cycle is the biogeochemical cycle by which carbon is exchanged between the biosphere, geosphere, hydrosphere, and atmosphere of the Earth. Burning fossil fuels leads to the addition of extra carbon into the cycle over what naturally occurs and is a major cause of climate change.

The black rat is a reservoir host for bubonic plague: the oriental rat fleas that infest these rats are vectors for the disease.
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasitic, a mutualistic, or a commensalist guest (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cells harbouring pathogenic (disease-causing) viruses, a bean plant hosting mutualistic (helpful) nitrogen-fixing bacteria. More specifically in botany, a host plant supplies food resources to micropredators, which have an evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. (Full article...)

" The problem of climate change is so large that it can't be solved by voluntary individual responses. It requires an economy-wide solution, i.e. one that limits the total carbon intake of the economy. "
