DRC-5593 (N-Acetyl-4-cyclohexylmethylcyclohexylamine) is a powerful lachrymatory agent that was suggested as an animal repellant and riot control agent. [1] [2] [3] [4]
A carnivore, or meat-eater, is an animal or plant whose nutrition and energy requirements are met by consumption of animal tissues as food, whether through predation or scavenging.
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation and parasitoidism. It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators.
The compound 2-chlorobenzalmalononitrile (also called o-chlorobenzylidene malononitrile; chemical formula: C10H5ClN2), a cyanocarbon, is the defining component of the lachrymatory agent commonly referred to as CS gas, a tear gas which is used as a riot control agent, and is banned for use in warfare due to the 1925 Geneva Protocol.
Bushmeat is meat from wildlife species that are hunted for human consumption. Bushmeat represents a primary source of animal protein and a cash-earning commodity in poor and rural communities of humid tropical forest regions of the world.
The spotted hyena, also known as the laughing hyena, is a hyena species, currently classed as the sole extant member of the genus Crocuta, native to sub-Saharan Africa. It is listed as being of least concern by the IUCN due to its widespread range and large numbers estimated between 27,000 and 47,000 individuals. The species is, however, experiencing declines outside of protected areas due to habitat loss and poaching. Populations of Crocuta, usually considered a subspecies of Crocuta crocuta, known as cave hyenas, roamed across Eurasia for at least one million years until the end of the Late Pleistocene. The spotted hyena is the largest extant member of the Hyaenidae, and is further physically distinguished from other species by its vaguely bear-like build, rounded ears, less prominent mane, spotted pelt, more dual-purposed dentition, fewer nipples, and pseudo-penis. It is the only placental mammalian species where females have a pseudo-penis and lack an external vaginal opening.
An apex predator, also known as a top predator or superpredator, is a predator at the top of a food chain, without natural predators of its own.
The Malayan civet, also known as the Malay civet and Oriental civet, is a viverrid native to the Malay Peninsula and the islands of Sumatra, Bangka, Borneo, the Riau Archipelago, and the Philippines. It is listed as "Least Concern" by IUCN as it is a relatively widely distributed, appears to be tolerant of degraded habitats, and occurs in a number of protected areas.
The South American coati, also known as the ring-tailed coati, is a coati species and a member of the raccoon family (Procyonidae), found in the tropical and subtropical parts of South America. An adult generally weighs from 2–7.2 kg (4.4–15.9 lb) and is 85–113 cm (33–44 in) long, with half of that being its tail. Its color is highly variable and the rings on the tail may be only somewhat visible, but its most distinguishing characteristic is that it lacks the largely white snout of its northern relative, the white-nosed coati.
The Colombian weasel, also known as Don Felipe's weasel, is a very rare species of New World weasel only known with certainty from the departments of Huila and Cauca in Colombia and nearby northern Ecuador. Both its scientific and alternative common name honours the mammalogist Philip "Don Felipe" Hershkovitz.
Many-sorted logic can reflect formally our intention not to handle the universe as a homogeneous collection of objects, but to partition it in a way that is similar to types in typeful programming. Both functional and assertive "parts of speech" in the language of the logic reflect this typeful partitioning of the universe, even on the syntax level: substitution and argument passing can be done only accordingly, respecting the "sorts".
The trophic level of an organism is the position it occupies in a food web. Within a food web, a food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way flow or a part of a wider food "web". Ecological communities with higher biodiversity form more complex trophic paths.
The ASME Medal, created in 1920, is the highest award bestowed by the ASME Board of Governors for "eminently distinguished engineering achievement". The award has been presented every year since 1996, and it consists of a $15,000 honorarium, a certificate, a travel supplement not to exceed $750, and a gold medal inscribed with the words, "What is not yet, may be".
A penis is a male sex organ that is used to inseminate female or hermaphrodite animals during copulation. Such organs occur in both vertebrates and invertebrates, but not in all male animals.
The binturong, also known as the bearcat, is a viverrid native to South and Southeast Asia. It is uncommon in much of its range, and has been assessed as Vulnerable on the IUCN Red List because of a declining population. It is estimated to have declined at least 30% since the mid-1980s. The binturong is the only species in the genus Arctictis.
Jeremy Randall Knowles was a professor of chemistry at Harvard University who served as dean of the Harvard University faculty of arts and sciences (FAS) from 1991 to 2002. He joined Harvard in 1974, received many awards for his research, and remained at Harvard until his death, leaving the faculty for a decade to serve as Dean. Knowles died on 3 April 2008 at his home.
Feral cats are an invasive species in Australia. Because they are not native to Australia and were only introduced by European colonists as pets in the early 1800s, native Australian animals did not co-evolve with them. As of 2016, some 3.8 million domestic cats and up to 6.3 million feral cats continue to live in Australia.
Scent rubbing is a behavior where a mammal rubs its body against an object in their environment, sometimes in ones covered with strongly odored substances. It is typically shown in carnivores, although many mammals exhibit this behavior. Lowering shoulders, collapsing the forelegs, pushing forward and rubbing the chin, temples, neck, or back is how this act is performed. A variety of different odors can elicit this behavior including feces, vomit, fresh or decaying meat, insecticide, urine, repellent, ashes, human food and so on. Scent rubbing can be produced by an animal smelling novel odors, which include manufactured smells such as perfume or motor oil and carnivore smells including feces and food smells.
Sir Francis Gerald William Knowles, 6th baronet was a distinguished British research biologist and zoologist, a Fellow of the Royal Society, who held the chair of anatomy at King's College London where he was Dean, to which he had come by a somewhat unorthodox route. He was, as The Times put it, "a fundamental scientist of outstanding calibre".
Biting is an action involving a set of teeth closing down on an object. It is a common zoological behavior, being found in toothed animals such as mammals, reptiles, amphibians, fish, and arthropods. Biting is also an action humans participate in, most commonly when chewing food. Myocytic contraction of the muscles of mastication is responsible for generating the force that initiates the preparatory jaw abduction (opening), then rapidly adducts (closes) the jaw and moves the top and bottom teeth towards each other, resulting in the forceful action of a bite. Biting is one of the main functions in the lives of larger organisms, providing them the ability to forage, hunt, eat, build, play, fight, protect, and much more. Biting may be a form of physical aggression due to predatory or territorial intentions. In animals, biting can also be a normal activity, being used for eating, scratching, carrying objects, preparing food for young, removing ectoparasites or irritating foreign objects, and social grooming. Humans can have the tendency to bite each other whether they are children or adults.
