Cedar Creek Ecosystem Science Reserve
The Cedar Creek Ecosystem Science Reserve is an ecological research site located primarily in East Bethel, Minnesota in the counties of Anoka and Isanti on the northern edge of the Minneapolis-Saint Paul metropolitan area. Name Originally the site was officially designated the ''Cedar Creek Forest'' which takes its name for Cedar Creek that winds through East Bethel. The bog where the site initially began was informally called by professors " Decodon Bog." The site was known as ''Cedar Creek Natural History Area'' until its change in 2007. Description Encompassing of native upland forests and prairie and lowland swamps and meadows, the site contains over 900 plots of long-term experimental research which evaluate plant competition and biodiversity. The herbivory research division examines animal and plant relationships. Led by prominent American ecologist G. David Tilman, the University schedules more than 130 faculty, post-doctoral researchers, graduate students, staff, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Historic Sites Act
The Historic Sites Act of 1935 was enacted by the United States Congress largely to organize the myriad federally own parks, monuments, and historic sites under the National Park Service and the United States Secretary of the Interior. However, it is also significant in that it declared for the first time "...that it is a national policy to preserve for public use historic sites, buildings, and objects of national significance...". {{Webarchive, url=https://web.archive.org/web/20170617121709/https://www.nps.gov/history/local-law/FHPL_HistSites.pdf , date=2017-06-17 , 49 Stat. 666; 16 U.S.C. sections 461-467. Thus it is the first assertion of historic preservation as a government duty, which was only hinted at in the 1906 |
Protected Areas Of Anoka County, Minnesota
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Controlled Burn
A controlled or prescribed burn, also known as hazard reduction burning, backfire, swailing, or a burn-off, is a fire set intentionally for purposes of forest management, farming, prairie restoration or greenhouse gas abatement. A controlled burn may also refer to the intentional burning of slash and fuels through burn piles. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Hazard reduction or controlled burning is conducted during the cooler months to reduce fuel buildup and decrease the likelihood of serious hotter fires. Controlled burning stimulates the germination of some desirable forest trees, and reveals soil mineral layers which increases seedling vitality, thus renewing the forest. Some cones, such as those of lodgepole pine and sequoia, are pyriscent, as well as many chaparral shrubs, meaning they require heat from fire to open cones to disperse seeds. In industrialized countries, controlled burning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tracking Animal Migration
Animal migration tracking is used in wildlife biology, conservation biology, ecology, and wildlife management to study animals' behavior in the wild. One of the first techniques was bird banding, placing passive ID tags on birds legs, to identify the bird in a future catch-and-release. Radio tracking involves attaching a small radio transmitter to the animal and following the signal with a RDF receiver. Sophisticated modern techniques use satellites to track tagged animals, and GPS tags which keep a log of the animal's location. With the Emergence of IoT the ability to make devices specific to the species or what is to be tracked is possible. One of the many goals of animal migration research has been to determine where the animals are going; however, researchers also want to know why they are going "there". Researchers not only look at the animals' migration but also what is between the migration endpoints to determine if a species is moving to new locations based on food den ...

Tracking Collar
GPS animal tracking is a process whereby biologists, scientific researchers or conservation agencies can remotely observe relatively fine-scale movement or wikt:migration, migratory patterns in a free-ranging wild animal using the Global Positioning System (GPS) and optional environmental sensors or automated data-retrieval technologies such as Argos system, Argos satellite uplink, Circuit Switched Data, mobile data telephony or GPRS and a range of analytical software tools. A GPS tracking device will normally record and store location data at a pre-determined interval or on interrupt by an environmental sensor. These data may be stored pending recovery of the device or relayed to a central data store or internet-connected computer using an embedded cellular network, cellular (GPRS), radio, or satellite modem. The animal's location can then be plotted against a map or chart in near real-time or, when analysing the track later, using a GIS package or custom software. GPS trackin ...

Arthur Tansley
Sir Arthur George Tansley FLS, FRS (15 August 1871 – 25 November 1955) was an English botanist and a pioneer in the science of ecology. Educated at Highgate School, University College London and Trinity College, Cambridge, Tansley taught at these universities and at Oxford, where he served as Sherardian Professor of Botany until his retirement in 1937. Tansley founded the ''New Phytologist'' in 1902 and served as its editor until 1931. He was a pioneer of the science of ecology in Britain, being heavily influenced by the work of Danish botanist Eugenius Warming, and introduced the concept of the ecosystem into biology. Tansley was a founding member of the first professional society of ecologists, the Central Committee for the Survey and Study of British Vegetation, which later organised the British Ecological Society, and served as its first president and founding editor of the ''Journal of Ecology''. Tansley also served as the first chairman of the British Nature Conservanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raymond Lindeman
Raymond Laurel Lindeman (1915 – June 29, 1942) was an ecologist whose graduate research is credited with being a seminal study in the field of ecosystem ecology, specifically on the topic of trophic dynamics. Graduate research work Lindeman completed his PhD at the University of Minnesota with his thesis work being concerned with the history and ecological dynamics of Cedar Bog Lake, which is located in the University of Minnesota's Cedar Creek Ecosystem Science Reserve in central Minnesota. While a postdoctoral researcher at Yale University with noted limnologist G. Evelyn Hutchinson, Lindeman submitted a chapter of his thesis for publication. His manuscript was initially rejected as being too generalized but was published after Hutchinson and others were able to convince the editor of the paper's merits. The publication appeared in the journal ''Ecology'' and establishes Ten percent law whereby only 10% of the energy consumed at one trophic level is transferred to higher ...

Limnologist
Limnology ( ; from Greek λίμνη, ''limne'', "lake" and λόγος, ''logos'', "knowledge") is the study of inland aquatic ecosystems. The study of limnology includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water. This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater.Wetzel, R.G. 2001. Limnology: Lake and River Ecosystems, 3rd ed. Academic Press () Water systems are often categorized as either running (lotic) or standing (lentic). Limnology includes the study of the drainage basin, movement of water through the basin and biogeochemical changes that occur en route. A more recent sub-discipline of limnology, termed landscape limnology, studies, manages, and seeks to conserve these ecosystems using a landscape perspective, by explicitly examining connections between an aquatic ecosystem and its drainage basin. Recently, the need to understa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minnesota Academy Of Science
Minnesota () is a state in the upper midwestern region of the United States. It is the 12th largest U.S. state in area and the 22nd most populous, with over 5.75 million residents. Minnesota is home to western prairies, now given over to intensive agriculture; deciduous forests in the southeast, now partially cleared, farmed, and settled; and the less populated North Woods, used for mining, forestry, and recreation. Roughly a third of the state is covered in forests, and it is known as the "Land of 10,000 Lakes" for having over 14,000 bodies of fresh water of at least ten acres. More than 60% of Minnesotans live in the Minneapolis–Saint Paul metropolitan area, known as the "Twin Cities", the state's main political, economic, and cultural hub. With a population of about 3.7 million, the Twin Cities is the 16th largest metropolitan area in the U.S. Other minor metropolitan and micropolitan statistical areas in the state include Duluth, Mankato, Moorhead, Rochester, and ...

Long Term Ecological Research Network
The Long Term Ecological Research Network (LTER) consists of a group of over 1800 scientists and students studying ecological processes over extended temporal and spatial scales. Twenty-eight LTER sites cover a diverse set of ecosystems. It is part of the International Long Term Ecological Research Network (ILTER). The project was established in 1980 and is funded by the National Science Foundation. Data from LTER sites is publicly available in the Environmental Data Initiative repository and findable through DataONE search. LTER sites There are 28 sites within the LTER Network across the United States, Puerto Rico, and Antarctica, each conducting research on different ecosystems. LTER sites are both physical places and communities of researchers. Some of the physical places are remote or protected from development, others are deliberately located in cities or agricultural areas. Either way, the program of research for each LTER is tailored to the most pressing and promising quest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
