Flathead Lake Biological Station
Flathead Lake Biological Station (FLBS) is a research station run by the University of Montana in Yellow Bay, Flathead Lake, Polson, Montana. It was first established by American ecologist and professor Morton John Elrod in 1899 on the Swan River near Bigfork. In 1909, it was moved to its current location. Year-round research began in 1967. Areas of ongoing research includes lake ecology, conservation genomics, stream, river, and floodplain ecology, microbial ecology, aquatic invasive species, and sensors and sensor networks. It is the second oldest biological field station in the United States, and the longest running freshwater field station in year-round operation in North America. History Montana was admitted to the Union in 1889. The University of Montana at Missoula, a public research university, received its charter in 1893, opening in 1895. Morton J. Elrod, the first biologist at the new university, began teaching in 1897.Dennison, George (2016). ''Montana's Pioneer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Research
The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century (with notable practitioners in previous centuries; see the article history of scientific method for additional detail.) It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypotheses, via induction, based on such observations; the testability of hypotheses, experimental and the measurement-based statistical testing of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are ''principles'' of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises. Although procedures vary from one field of inquiry to another, the underlying process is frequently t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse-drawn Covered Wagon Yellow Bay Biological Station 1903
A horse-drawn vehicle is a mechanized piece of equipment pulled by one horse or by a team of horses. These vehicles typically had two or four wheels and were used to carry passengers and/or a load. They were once common worldwide, but they have mostly been replaced by automobiles and other forms of self-propelled transport. General Horses were domesticated circa 3500 BCE. Prior to that oxen were used. Historically a wide variety of arrangements of horses and vehicles have been used, from chariot racing, which involved a small vehicle and four horses abreast, to horsecars or trollies, which used two horses to pull a car that was used in cities before electric trams were developed. A two-wheeled horse-drawn vehicle is a cart (see various types below, both for carrying people and for goods). Four-wheeled vehicles have many names – one for heavy loads is most commonly called a wagon. Very light carts and wagons can also be pulled by donkeys (much smaller than horses), ponies o ...

Mussel
Mussel () is the common name used for members of several families of bivalve molluscs, from saltwater and freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval. The word "mussel" is frequently used to mean the bivalves of the marine family Mytilidae, most of which live on exposed shores in the intertidal zone, attached by means of their strong byssal threads ("beard") to a firm substrate. A few species (in the genus '' Bathymodiolus'') have colonised hydrothermal vents associated with deep ocean ridges. In most marine mussels the shell is longer than it is wide, being wedge-shaped or asymmetrical. The external colour of the shell is often dark blue, blackish, or brown, while the interior is silvery and somewhat nacreous. The common name "mussel" is also used for many freshwater bivalves, including the freshwater pearl mussels. Freshwater mussel spec ...

Zebra Mussel
The zebra mussel (''Dreissena polymorpha'') is a small freshwater mussel. The species originates from the lakes of southern Russia and Ukraine, but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide. Since the 1980s, the species has invaded the Great Lakes, Hudson River, and Lake Travis. The species was first described in 1769 by German zoologist Peter Simon Pallas in the Ural, Volga, and Dnieper Rivers. Zebra mussels get their name from a striped pattern commonly seen on their shells, though it is not universally present. They are usually about the size of a fingernail, but can grow to a maximum length around . Shells are D-shaped, and attached to the substrate with strong byssal fibers, which come out of their umbo on the dorsal (hinged) side. Ecology Zebra mussels and the closely related and ecologically similar quagga mussels are filter-feeding organisms; they remove particles from the water colum ...

Quagga Mussel
The quagga mussel (''Dreissena rostriformis'', also known as ''Dreissena bugensis'' or ''Dreissena rostriformis bugensis'') is a species (or subspecies) of freshwater mussel, an aquatic bivalve mollusk in the family Dreissenidae. It has an average lifespan of 3 to 5 years. The species is indigenous to the Dnieper River drainage of Ukraine, and is named after the quagga, an extinct subspecies of African zebra, possibly because, like the quagga, its stripes fade out towards the ventral side. The invasive quagga mussel is currently of major concern as it spreads in the rivers and lakes of Europe and also in the Great Lakes of North America where it was brought to by overseas shippers that use the Saint Lawrence Seaway. Appearance The quagga mussel shell is generally black, yellow, and/or zig-zagged. However, a large range of shell morphologies is seen, including a distinct morph in Lake Erie that is pale or completely white. The shell has a rounded carina and a convex ventral ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin ('' Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter ('' Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range ...

Environmental DNA
Environmental DNA or eDNA is DNA that is collected from a variety of environmental samples such as soil, seawater, snow or air, rather than directly sampled from an individual organism. As various organisms interact with the environment, DNA is expelled and accumulates in their surroundings from various sources. In recent years, eDNA has been used as a tool to detect endangered wildlife that were otherwise unseen. In 2020, human health researchers began repurposing eDNA techniques to track the COVID-19 pandemic. Example sources of eDNA include, but are not limited to, feces, mucus, gametes, shed skin, carcasses and hair. Samples can be analyzed by high-throughput DNA sequencing methods, known as metagenomics, metabarcoding, and single-species detection, for rapid monitoring and measurement of biodiversity. In order to better differentiate between organisms within a sample, DNA metabarcoding is used in which the sample is analyzed and uses previously studied DNA lib ...

Charles Redd Center For Western Studies
Charles is a masculine given name predominantly found in English and French speaking countries. It is from the French form ''Charles'' of the Proto-Germanic name (in runic alphabet) or ''*karilaz'' (in Latin alphabet), whose meaning was "free man". The Old English descendant of this word was '' Ċearl'' or ''Ċeorl'', as the name of King Cearl of Mercia, that disappeared after the Norman conquest of England. The name was notably borne by Charlemagne (Charles the Great), and was at the time Latinized as ''Karolus'' (as in ''Vita Karoli Magni''), later also as '' Carolus''. Some Germanic languages, for example Dutch and German, have retained the word in two separate senses. In the particular case of Dutch, ''Karel'' refers to the given name, whereas the noun ''kerel'' means "a bloke, fellow, man". Etymology The name's etymology is a Common Germanic noun ''*karilaz'' meaning "free man", which survives in English as churl (< Old English ''ċeorl''), which developed its ...

South 40
South 40 is an American colloquialism with its origins in the Homestead Act of 1862. Adult heads of families were given of public land In all modern states, a portion of land is held by central or local governments. This is called public land, state land, or Crown land ( Australia, and Canada). The system of tenure of public land, and the terminology used, varies between countri ... provided they could "prove" (improve) the land by constructing a dwelling of some sort on the land and cultivating the land in some manner. After five years of residence, the deed was transferred to the homesteader. The homesteads, being , were easily divisible into quarters of each. The south 40 would therefore refer to the south {{convert, 40, acre, m2. "South 40" as a name has been used by a multitude of businesses, bands and organizations. The South 40 is also the name for a section of Washington University in St. Louis's campus. The southernmost 40 acres of campus, this area houses most ...
