Stridulation is the act of producing sound by rubbing together certain body parts. This behavior is mostly associated with insects, but other animals are known to do this as well, such as a number of species of fish, snakes and spiders. The mechanism is typically that of one structure with a well-defined lip, ridge, or nodules being moved across a finely-ridged surface or vice versa, and vibrating as it does so, like the dragging of a phonograph needle across a vinyl record. Sometimes it is the structure bearing the file which resonates to produce the sound, but in other cases it is the structure bearing the scraper, with both variants possible in related groups. Common onomatopoeic words for the sounds produced by stridulation include chirp and chirrup.
The Arabian Desert is a vast desert wilderness in Western Asia. It stretches from Yemen to the Persian Gulf and Oman to Jordan and Iraq. It occupies most of the Arabian Peninsula, with an area of 2,330,000 square kilometers (900,000 sq mi). It is the fifth largest desert in the world, and the largest in Asia. At its center is Ar-Rub'al-Khali, one of the largest continuous bodies of sand in the world.
The scarlet ibis is a species of ibis in the bird family Threskiornithidae. It inhabits tropical South America and part of the Caribbean. In form, it resembles most of the other twenty-seven extant species of ibis, but its remarkably brilliant scarlet coloration makes it unmistakable. It is one of the two national birds of Trinidad and Tobago, and its Tupi–Guarani name, guará, is part of the name of several municipalities along the coast of Brazil.
The Rub' al Khali, the "Empty Quarter") is the sand desert (erg) encompassing most of the southern third of the Arabian Peninsula. The desert covers some 650,000 km2 (250,000 sq mi) including parts of Saudi Arabia, Oman, the United Arab Emirates, and Yemen. It is part of the larger Arabian Desert.
Anting is a maintenance behaviour during which birds rub insects, usually ants, on their feathers and skin. The bird may pick up the insects in its bill and rub them on the body, or the bird may lie in an area of high density of the insects and perform dust bathing-like movements. The insects secrete liquids containing chemicals such as formic acid, which can act as an insecticide, miticide, fungicide, or bactericide. Alternatively, anting could make the insects edible by removing the distasteful acid, or, possibly supplement the bird's own preen oil. Instead of ants, birds can also use millipedes. More than 200 species of bird are known to ant. A possibly related behaviour, self-anointing, is seen in many mammals.
The phylum "Bacteroidetes" is composed of three large classes of Gram-negative, nonsporeforming, anaerobic or aerobic, and rod-shaped bacteria that are widely distributed in the environment, including in soil, sediments, and sea water, as well as in the guts and on the skin of animals.
Ipomoea is the largest genus in the flowering plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, water convolvulus or kangkung, sweet potato, bindweed, moonflower, etc.
Centranthus ruber, the red valerian, spur valerian, kiss-me-quick, fox's brush, devil's beard or Jupiter's beard, is a popular garden plant grown for its ornamental flowers.
Scent glands are exocrine glands found in most mammals. They produce semi-viscous secretions which contain pheromones and other semiochemical compounds. These odor-messengers indicate information such as status, territorial marking, mood, and sexual power. The odor may be subliminal—not consciously detectable. Though it is not their primary function, the salivary glands may also function as scent glands in some animals.
The Texas blind salamander is a rare cave-dwelling troglobite amphibian native to San Marcos, Hays County, Texas, specifically the San Marcos Pool of the Edwards Aquifer.
Crotalus ruber is a venomous pit viper species found in southwestern California in the United States and Baja California in Mexico. Three subspecies are currently recognized, including the nominate subspecies described here.
The red myotis is a vesper bat species found in Argentina, Brazil, Paraguay and Uruguay.
The reddish hermit is a species of bird in the family Trochilidae, the hummingbirds. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, Venezuela, and in the Guianas. At 7.5 cm (3 in) and a weight under 3 grams, it is among the smallest of the hermits and smallest birds overall. Its natural habitats are forest and woodland, primarily humid.
Scinax ruber is a species of frog in the family Hylidae. It is known in English as the red snouted treefrog or red-snouted treefrog, sometimes also Allen's snouted treefrog, the latter referring to the now-synonymized Scinax alleni. This widespread species is found in much of Amazonian and northern coastal South America and into Panama, as well as in some Caribbean islands as introduced populations. It is a complex containing several cryptic species.
The red salamander is a species of salamander in the family Plethodontidae endemic to the eastern United States. Its skin is orange/red with random black spots. Its habitats are temperate forests, small creeks, ponds, forests, temperate shrubland, rivers, intermittent rivers, freshwater, trees springs. Overall this species is common and widespread, but locally it has declined because of habitat loss and it is considered threatened in Indiana. Red salamanders eat insects, earthworms, spiders, small crustaceans, snails and smaller salamanders. The red salamander, as a member of the family Plethodontidae, lacks lungs and respires through its skin.
Noack's roundleaf bat is a species of bat in the family Hipposideridae. It is found throughout tropical Africa. Its natural habitats are subtropical or tropical moist lowland forests, moist savanna, caves, and subterranean habitats.
The bar jack, also known as the carbonero, red jack, blue-striped cavalla or passing jack, is a common species of inshore marine fish classified in the jack family, Carangidae. The bar jack is distributed through the western Atlantic Ocean from New Jersey and Bermuda in the north to Venezuela and possibly Brazil in the south, with the largest population in the Gulf of Mexico and West Indies. The bar jack is most simply distinguished from similar jacks by its dark horizontal bar which runs along the back and down the caudal fin, often accompanied by an electric blue stripe immediately below it. Other more detailed differences include dentition and soft ray counts. The bar jack is a moderately large species, growing to a recorded maximum of 65 cm and a weight of 6.8 kg. The species inhabits clear shallow waters, often over coral reefs where it lives either solitarily or in large schools, taking various fishes, crustaceans and cephalopods as prey. Studies in Cuba indicate spawning occurs between March and August, with sexual maturity reached at 26 cm. It is a relatively popular sport fish and can be caught on light tackle with a variety of lures and baits. It is considered to be a good food fish, however many recorded ciguatera cases are attributed to the species, with most cases reported on the island of St. Thomas traced to this single species.
Clathrus ruber is a species of fungus in the family Phallaceae, and the type species of the genus Clathrus. It is commonly known as the latticed stinkhorn, the basket stinkhorn, or the red cage, alluding to the striking fruit bodies that are shaped somewhat like a round or oval hollow sphere with interlaced or latticed branches. The fungus is saprobic, feeding off decaying woody plant material, and is often found alone or in groups in leaf litter on garden soil, grassy places, or on woodchip garden mulches. Although considered primarily a European species, C. ruber has been introduced to other areas, and now has a wide distribution that includes all continents except Antarctica. The species was illustrated in the scientific literature during the 16th century, but was not officially described until 1729.
Globigerinoides is an extant genus of shallow-water planktonic foraminifera of family Globigerinidae. First appearing in the Oligocene these foraminifera are found in all modern oceans. Species of this genus occupy the euphotic zone, generally at depths between 10-50m, in waters which cover a range of salinities and temperatures. They are a shorter lived species, especially when compared to Globorotalia genus. As a genus Globigerinoides is widely used in various fields of research including biostratigraphy, isotope geochemistry, biogeochemistry, climatology, and oceanography.
Crossotini is a tribe of longhorn beetles of the subfamily Lamiinae. It was described by Thomson in 1864.
