Demographics Of Denmark
This article is about the demographic features of the population of Denmark, including ethnicity, education level, health of the populace, economic status, religious affiliations, and other aspects of the population. Population Since 1980, the number of people of Danish descent, defined as having at least one parent who was born in Denmark and has Danish citizenship, has remained constant at around 5 million in Denmark, and nearly all the population growth from 5.1 up to the 2018 total of 5.8 million was due to immigration. Demographic statistics according to the World Population Review in 2019. *One birth every 8 minutes *One death every 9 minutes *One net migrant every 34 minutes *Net gain of one person every 24 minutes Fertility The total fertility rate is the number of children born per woman. It is based on fairly good data for the entire period. Sources: Our World In Data and Gapminder Foundation. Total fertility rate 1.78 children born/woman (2018 es ...

Restoration Ecology
Restoration ecology is the scientific study supporting the practice of ecological restoration, which is the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human interruption and action. Effective restoration requires an explicit goal or policy, preferably an unambiguous one that is articulated, accepted, and codified. Restoration goals reflect societal choices from among competing policy priorities, but extracting such goals is typically contentious and politically challenging. Natural ecosystems provide ecosystem services in the form of resources such as food, fuel, and timber; the purification of air and water; the detoxification and decomposition of wastes; the regulation of climate; the regeneration of soil fertility; and the pollination of crops. These ecosystem processes have been estimated to be worth trillions of dollars annually. There is consensus in the scientific community that the current envi ...

Ministry Of Environment (Denmark)
Ministry of the Environment of Denmark ( da, Miljøministeriet) is the Danish ministry in charge of almost all matters concerning environmental issues in Denmark. The head office is in Copenhagen. Created in 1971 as the Ministry of Pollution Combating ("''Ministeriet for forureningsbekæmpelse''"), it changed its name in 1973 to the current Ministry of the Environment. However, from 1994 to 2005 it was known as the Ministry of Environment and Energy ("''Miljø- og Energiministeriet''"), as the ministry was merged with the Ministry of Energy. In 2005, the energy sector was detached again and the ministry reverted to the old name. In a press release on 21 March 2007, the ministry announced that it would be hosting the COP-15 summit in 2009.(created on 1 January 2011 by a merger of Miljøklagenævnet and Naturklagenævnet) See also * Wind power in Denmark *Minister for the Environment (Denmark) Notes External links Ministry of the Environment 1971 establishments in De ...

Maasai Mara
Maasai Mara, also sometimes spelled Masai Mara and locally known simply as The Mara, is a large national game reserve in Narok, Kenya, contiguous with the Serengeti National Park in Tanzania. It is named in honor of the Maasai people, the ancestral inhabitants of the area, who migrated to the area from the Nile Basin. Their description of the area when looked at from afar: "Mara" means "spotted" in the local Maasai language, due to the many short bushy trees which dot the landscape. Maasai Mara is one of the most famous and important wildlife conservation and wilderness areas in Africa, world-renowned for its exceptional populations of lion, leopard, cheetah and African bush elephant. It also hosts the Great Migration, which secured it as one of the Seven Natural Wonders of Africa, and as one of the ten Wonders of the World. The Greater Mara ecosystem encompasses areas known as the Maasai Mara National Reserve, the Mara Triangle, and several Maasai Conservancies, including ...

Ernst Haeckel
Ernst Heinrich Philipp August Haeckel (; 16 February 1834 – 9 August 1919) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ''ecology'', ''phylum'', ''phylogeny'', and '' Protista.'' Haeckel promoted and popularised Charles Darwin's work in Germany and developed the influential but no longer widely held recapitulation theory ("ontogeny recapitulates phylogeny") claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development, or phylogeny. The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his '' Kunstformen der Natur'' ("Art Forms of Nature"), a book which would go on to influence the Art Nouveau artistic ...

Effects Of Climate Change On Biomes
Climate change is already now altering biomes, adversely affecting terrestrial and marine ecosystems. Climate change represents long-term changes in temperature and average weather patterns. This leads to a substantial increase in both the frequency and the intensity of extreme weather events. As a region's climate changes, a change in its flora and fauna follows. For instance, out of 4000 species analyzed by the IPCC Sixth Assessment Report, half were found to have shifted their distribution to higher latitudes or elevations in response to climate change.Parmesan, C., M.D. Morecroft, Y.

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic ('' genetic variability''), species ('' species diversity''), and ecosystem ('' ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biogeography
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area.Brown University, "Biogeography." Accessed February 24, 2014. . Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals. Mycogeography is the branch that studies distribution of fungi, such as mushrooms. Knowledge of spatial variation in the numbers and types of organisms is as vital to us today as it was to our early human ancestors, as we adapt to heterogeneous but geographically predictable environments. Biogeography is an integrative field of inquiry that unites concepts and information from ecology, evolutionary biology, taxonomy, geology, physical geography, palaeontology, and climatology.Dansereau, ...

Macroecology
Macroecology is the subfield of ecology that deals with the study of relationships between organisms and their environment at large spatial scales to characterise and explain statistical patterns of abundance, distribution and diversity. The term was coined in a small monograph published in Spanish in 1971 by Guillermo Sarmiento and Maximina Monasterio, two Venezuelan researchers working in tropical savanna ecosystemsLevin, S. A., Carpenter, S. R., Godfray, H. C. J., Kinzig, A. P., Loreau, M., Losos, J. B., ... & Wilcove, D. S. (Eds.). (2012). The Princeton guide to ecology. Princeton University Press. and later used by James Brown of the University of New Mexico and Brian Maurer of Michigan State University in a 1989 paper in ''Science''. Macroecology approaches the idea of studying ecosystems using a "top down" approach. It seeks understanding through the study of the properties of the system as a whole; Kevin Gaston and Tim Blackburn make the analogy to seeing the forest for t ...
