White-sided Jackrabbit
The white-sided jackrabbit (''Lepus callotis''), also known as the Mexican hare, is a jackrabbit found in a limited range in North America, from southern New Mexico to northwestern and central Mexico. The animal is considered threatened in New Mexico, with its numbers in decline in recent years; its presence is uncertain in Arizona. Habitat The white-sided jackrabbit inhabits plateaus at high elevations, including the grassy plains of southwestern New Mexico and the open plains of the southern Mexican tableland. It avoids areas of hills or mountains. It prefers level lands full of grasses and also avoids areas with trees and shrubs. Description The white-sided jackrabbit's body length ranges from long. Its tail grows to lengths of . Its legs grow from in the front and the back legs can grow from long. The white-sided jackrabbit's ears grow when fully grown. The fore paws have five toes while the back paws have four. All toes end in sturdy claws. Some sexual dimorphism is pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Georg Wagler
Johann Georg Wagler (28 March 1800 – 23 August 1832) was a German herpetologist and ornithologist. Wagler was assistant to Johann Baptist von Spix, and gave lectures in zoology at the Ludwig Maximilian University of Munich after it was moved to Munich. He worked on the extensive collections brought back from Brazil by Spix, and published partly together with him books on reptiles from Brazil. Wagler wrote ''Monographia Psittacorum'' (1832), which included the correct naming of the blue macaws. In 1832, Wagler died of an accidental self-inflicted gunshot wound while out collecting in München-Moosach. Life Johann Georg Wagler was a German naturalist and scientist in the 19th century, whose works primarily focused on herpetology and ornithology (Beolens, Watkins & Grayson, 2011). Johan Georg Wagler was born on the 28th of March 1800, in the city of Nuremberg, where the Chancellor of the City Court was Wagler's father (Wagler, 1884). After taking up gymnastics at Nuremberg, J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escape Behavior
Escape response, escape reaction, or escape behavior is a mechanism by which animals avoid potential predation. It consists of a rapid sequence of movements, or lack of movement, that position the animal in such a way that allows it to hide, freeze, or flee from the supposed predator. Often, an animal's escape response is representative of an instinctual defensive mechanism, though there is evidence that these escape responses may be learned or influenced by experience. The classical escape response follows this generalized, conceptual timeline: threat detection, escape initiation, escape execution, and escape termination or conclusion. Threat detection notifies an animal to a potential predator or otherwise dangerous stimulus, which provokes escape initiation, through neural reflexes or more coordinated cognitive processes. Escape execution refers to the movement or series of movements that will hide the animal from the threat or will allow for the animal to flee. Once the animal ...

Sedge Nutgrass
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus ''Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wright Buckwheat
''Eriogonum wrightii'' is a species of wild buckwheat known by the common names bastardsage and Wright's buckwheat. It is native to the Southwestern United States, California, and northwest Mexico, where it grows in many plant communities, such as chaparral, in rocky habitats from mountains to deserts.

Wooly Indian Wheat
Wool is the textile fibre obtained from sheep and other mammals, especially goats, rabbits, and camelids. The term may also refer to inorganic materials, such as mineral wool and glass wool, that have properties similar to animal wool. As an animal fibre, wool consists of protein together with a small percentage of lipids. This makes it chemically quite distinct from cotton and other plant fibres, which are mainly cellulose. Characteristics Wool is produced by follicles which are small cells located in the skin. These follicles are located in the upper layer of the skin called the epidermis and push down into the second skin layer called the dermis as the wool fibers grow. Follicles can be classed as either primary or secondary follicles. Primary follicles produce three types of fiber: kemp, medullated fibers, and true wool fibers. Secondary follicles only produce true wool fibers. Medullated fibers share nearly identical characteristics to hair and are long but lack crimp a ...

Blue Grama
''Bouteloua gracilis'', the blue grama, is a long-lived, warm-season ( C4) perennial grass, native to North America. It is most commonly found from Alberta, Canada, east to Manitoba and south across the Rocky Mountains, Great Plains, and U.S. Midwest states, onto the northern Mexican Plateau in Mexico. Blue grama accounts for most of the net primary productivity in the shortgrass prairie of the central and southern Great Plains. It is a green or greyish, low-growing, drought-tolerant grass with limited maintenance. Description Blue grama has green to greyish leaves less than wide and long. The overall height of the plant is at maturity. The flowering stems ( culms) are long. At the top are one to four, usually two, comb-like spikes, which extend out at a sharp angle from the flowering stem. Each spike has 20 to 90 spikelets. Each spikelet is long, and has one fertile floret and one or two reduced sterile ones. Below the florets are two glumes, one long and the ot ...

Fiddleneck
''Amsinckia'' is a genus of flowering plants commonly known as fiddlenecks. The common name is derived from the flower stems, which curl over at the top in a manner reminiscent of the head of a fiddle. Fiddlenecks are in the family Boraginaceae, along with borage and forget-me-nots. The genus is named after the patrician Amsinck family in honour of the Hamburg head of state and patron of botany Wilhelm Amsinck (1752–1831).Umberto Quattrocchi (ed.), ''CRC World Dictionary of Medicinal and Poisonous Plants: Common Names, Scientific Names, Eponyms, Synonyms, and Etymology'', CRC Press, 2016, p. 263, Distribution and Description The fiddlenecks are native to western North America and south-western South America, but they are naturalized in other regions. They are annuals, many of them bristly. Most have an erect stem, whose height varies from 20 to 120 cm. In most species the flowers are yellow, often with an orange tinge. Most are found at relatively low altitudes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bouteloua Dactyloides
''Bouteloua dactyloides'', commonly known as buffalograss or a buffalo grass, is a North American prairie grass native to Canada, Mexico, and the United States. It is a shortgrass found mainly on the High Plains and is co-dominant with blue grama (''B. gracilis'') over most of the shortgrass prairie. Buffalo grass in North America is not the same species of grass commonly known as "buffalo" in Australia. It should not be confused with '' Stenotaphrum secundatum'' varieties such as 'Sir Walter' or 'Palmetto'. Description Buffalograss is a warm-season perennial shortgrass. It is drought-, heat-, and cold-resistant. Foliage is usually high, though in the southern Great Plains, foliage may reach . Buffalograss is usually dioecious, but sometimes monoecious or with perfect flowers. Flower stalks are tall.

Animal Communication
Animal communication is the transfer of information from one or a group of animals (sender or senders) to one or more other animals (receiver or receivers) that affects the current or future behavior of the receivers. Information may be sent intentionally, as in a courtship display, or unintentionally, as in the transfer of scent from predator to prey. Information may be transferred to an "audience" of several receivers. Animal communication is a rapidly growing area of study in disciplines including animal behavior, sociology, neurology and animal cognition. Many aspects of animal behavior, such as symbolic name use, emotional expression, learning and sexual behavior, are being understood in new ways. When the information from the sender changes the behavior of a receiver, the information is referred to as a "signal". Signalling theory predicts that for a signal to be maintained in the population, both the sender and receiver should usually receive some benefit from the interact ...

Cyperus Rotundus
''Cyperus rotundus'' (coco-grass, Java grass, nut grass, purple nut sedge or purple nutsedge, red nut sedge, Khmer ''kravanh chruk''Martin, Robert & Pol Chanthy, 2009''Weeds of Upland Cambodia'', ACIAR Monagraph 141, Canberra.) is a species of sedge (Cyperaceae) native to Africa, southern and central Europe (north to France and Austria), and southern Asia. The word ''cyperus'' derives from the Greek , ''kyperos'', and ''rotundus'' is from Latin, meaning "round". The earliest attested form of the word ''cyperus'' is the Mycenaean Greek , ''ku-pa-ro'', written in Linear B syllabic script. Description ''Cyperus rotundus'' is a perennial plant, that may reach a height of up to . The names "nut grass" and "nut sedge" – shared with the related species ''Cyperus esculentus'' – are derived from its tubers, that somewhat resemble nuts, although botanically they have nothing to do with nuts. As in other Cyperaceae, the leaves sprout in ranks of three from the base of the plant, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
