Ecology is distinguished from natural history, which deals primarily with the descriptive study of organisms. It is a sub-discipline of biology, which is the study of life. There are many practical applications of ecology in conservation biology, wetland management, natural resource management (agricu...
Recent studies suggest that arthropod diversity in German forests is declining. Currently, different national programs are being developed to monitor arthropod trends and to unravel the effects of forest management on biodiversity in forests. To establish effective long-term monitoring programs, a set of...
For instance, whether the seabed is viewed in the context of submarine geology, the water column, the earth-ocean–atmosphere system, or a coastal economic system influences whether mining policy will be developed using a framework of localised mining codes, the integrated management of a Marine ...
in the water column and the occurrence of food starvation at the seafloor (and hence the coeval low biomass of benthic organisms31,32,33). Conversely, the cooling trend following peak EECO warmth was accompanied by the opening up of new niches for deeper dwelling zooplankton and a consequent ...
Some animals live their entire lives in one tide pool because tide pools are full of life. Many of the animals are invertebrates, but there are alsomarine algae, which provide food and shelter, plankton in the water column, and fresh nutrients delivered regularly by the tides. There are also...

Marine biologists have greatly helped in understanding how aquatic life is interconnected. Takecoral reefs, for example. These vibrant underwater communities support 25% of all marine species despite covering only a tiny fraction of the ocean floor. ...
Vector data is data in which points, lines and polygons represent features such as properties, cities, roads, mountains and bodies of water. For example, a visual representation that uses vector data might include houses represented by points, roads represented by lines and entire towns represented...
