Roadkill
Roadkill is a wild animal that has been killed by collision with motor vehicles. Wildlife-vehicle collisions (WVC) have increasingly been the topic of academic research to understand the causes, and how they can be mitigated. History Essentially non-existent before the advent of mechanized transport, roadkill is associated with increasing automobile speed in the early 20th century. In 1920, naturalist Joseph Grinnell wrote of his observations in the state of California that "this is a relatively new source of fatality; and if one were to estimate the entire mileage of such roads in the state, the mortality must mount into the hundreds and perhaps thousands every 24 hours." In Europe and North America, deer are the animal most likely to cause vehicle damage. Causes The development of roads affects wildlife by altering and isolating habitat and populations, deterring the movement of wildlife, and resulting in extensive wildlife mortality. One writer states that "our insulate ...

Citizen Science
The term citizen science (synonymous to terms like community science, crowd science, crowd-sourced science, civic science, participatory monitoring, or volunteer monitoring) is research conducted with participation from the general public, or amateur/nonprofessional researchers or participants of science, social science and many other disciplines. There are variations in the exact definition of citizen science, with different individuals and organizations having their own specific interpretations of what citizen science encompasses. Citizen science is used in a wide range of areas of study including ecology, biology and conservation, health and medical research, astronomy, media and communications and information science. There are different applications and functions of "citizen science" in research projects. Citizen science can be used as a methodology where public volunteers help in collecting and classifying data, improving the scientific community's capacity. Citizen sc ...

Windshield Phenomenon
The windshield phenomenon (or windscreen phenomenon) is the observation that fewer dead insects accumulate on the windshields and front bumpers of people's cars since the early 2000s. It has been attributed to a global decrease of insect populations caused by human activity, e.g. use of pesticides. Background As early as the 2000s it became a commonplace observation among drivers that after a long drive, windshields no longer had to be cleaned of numerous insects. In 2016, Canadian naturalist John Acorn noted that the phenomenon had recently become a meme but questioned whether it is "reasonable to assume that windshields can tell us something about the overall numbers of insects" and also that "humans are notoriously bad at detecting trends". The windshield phenomenon was discussed widely in 2017 after major publications and other media reported the topic of reductions of insect abundance during the last few decades. Entomologists stated that they had noticed that they no lon ...

Rumble Strip
Rumble strips (also known as sleeper lines or alert strips) are a traffic calming feature to alert inattentive drivers of potential danger, by causing a tactile vibration and audible rumbling transmitted through a vehicle's wheels into its interior. A rumble strip is applied along the direction of travel following an edgeline or centerline, to alert drivers when they drift from their lane. Rumble strips may also be installed in a series ''across'' the direction of travel, to warn drivers of a stop or slowdown ahead, or of an approaching danger spot. In favorable circumstances, rumble strips are effective (and cost-effective) at reducing accidents due to inattention. The effectiveness of shoulder rumble strips is largely dependent on a wide and stable road shoulder for a recovery, but there are several other less obvious factors that engineers consider during design. Other names Rumble strips are also known as audible lines, sleepy bumps, wake up calls, ruffles strips (n ...

Evolutionary Pressure
Evolutionary pressure, selective pressure or selection pressure is exerted by factors that reduce or increase reproductive success in a portion of a population, driving natural selection. It is a quantitative description of the amount of change occurring in processes investigated by evolutionary biology, but the formal concept is often extended to other areas of research. In population genetics, selective pressure is usually expressed as a selection coefficient. Amino acids selective pressure It has been shown that putting an amino acid bio-synthesizing gene like ''HIS4'' gene under amino acid selective pressure in yeast causes enhancement of expression of adjacent genes which is due to the transcriptional co-regulation of two adjacent genes in Eukaryota. Antibiotic resistance Drug resistance in bacteria is an example of an outcome of natural selection. When a drug is used on a species of bacteria, those that cannot resist die and do not produce offspring, while those that ...

Deer Horn
A deer horn, or deer whistle, is a whistle mounted on automobiles intended to help prevent collisions with deer. Air moving through the device produces sound (ultrasound Ultrasound is sound with frequency, frequencies greater than 20 Hertz, kilohertz. This frequency is the approximate upper audible hearing range, limit of human hearing in healthy young adults. The physical principles of acoustic waves apply ... in some models), intended to warn deer of a vehicle's approach. Deer are highly unpredictable, skittish animals whose normal reaction to an unfamiliar sound is to stop, look and listen to determine if they are being threatened. If the whistle gives them advance warning, they may freeze on the roadside, rather than running across the road into the path of the vehicle. In Australia, a different product, with electrically powered speakers (Shu Roo), is used to decrease collisions with kangaroos. Researchers with the University of Wisconsin–Madison measured three d ...

Chicane
A chicane () is a serpentine curve in a road, added by design rather than dictated by geography. Chicanes add extra turns and are used both in motor racing and on roads and streets to slow traffic for safety. For example, one form of chicane is a short, shallow S-shaped turn that requires the driver to turn slightly left and then slightly right to continue on the road, requiring the driver to reduce speed. The word ''chicane'' is derived from the French verb ''chicaner'', which means "to create difficulties" or "to dispute pointlessly", "quibble", which is also the root of the English noun ''chicanery''. The Spanish verb ''chicanear'' also means "to use trickery". Motor racing On modern racing circuits, chicanes are usually located after long straights, making them a prime location for overtaking. They can be placed tactically by circuit designers to prevent vehicles from reaching speeds deemed to be unsafe. A prime example of this is the three chicanes at the Autodromo Nazi ...
