Knight Anole
The knight anole (''Anolis equestris'') is the largest species of anole () in the Dactyloidae family. Other common names include Cuban knight anole or Cuban giant anole, highlighting its native country, but it has also been introduced to Florida. In its native Cuba, this large anole is called ''chupacocote''. Taxonomy The knight anole is part of a group of overall similar (in both appearance and behavior, all are crown-giant ecomorphs) anoles from Cuba known as the ''equestris'' species complex, including '' A. baracoae'', '' A. luteogularis'', '' A. noblei'', '' A. pigmaequestris'' and '' A. smallwoodi''. These and a few other anole species from Cuba, Hispaniola and Puerto Rico are sometimes placed in their own genus, '' Deiroptyx''. Geographic range and habitat Knight anoles are native to Cuba, but have been widely introduced into South Florida, where they reproduce and spread readily as an invasive species. They cannot withstand cold temperatures; in winter freezes in Fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blasius Merrem
Blasius Merrem (4 February 1761 – 23 February 1824) was a German naturalist, zoologist, ornithologist, mathematician, and herpetologist. In 1804, he became the professor of political economy and botany at the University of Marburg. Early life Merrem was born at Bremen, and studied at the University of Göttingen under Johann Friedrich Blumenbach. He developed an interest in zoology, particularly ornithology. Ornithology He is remembered chiefly as the first ornithologist to propose a division of birds into Ratitae ( ratites or running birds, with a flat sternum) and Carinatae (carinates or flying birds, with a keeled sternum), which formed part of his classification of birds in ''Tentamen Systematis Naturalis Avium'', published in Berlin in 1816 (in ''Abhandlugen Akad. Wiss. Berlin 1812–1813: Phys. Kl.''). Herpetology Similarly, in his 1820 opus, ''Versuch eines Systems der Amphibien'', he was the first scientist to accurately separate amphibians from reptiles, to sep ...

Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Terrarium
A terrarium (plural: terraria or terrariums) is usually a sealable glass container containing soil and plants that can be opened for maintenance to access the plants inside; however, terraria can also be open to the atmosphere. Terraria are often kept as ornamental items. A closed terrarium's transparent walls allow heat and light to enter, creating a unique environment for plant growth. Heat entering the sealed container allows the creation of a small water cycle due to evaporating moisture from the soil and plants. The water vapor then condenses onto the walls of the container, eventually falling back onto the plants and soil below. Light passing through the transparent walls, allowing photosynthesis, with the constant water supply provide an ideal environment for plants. Open terraria are not sealed and are better suited to plants requiring a more arid environment. History The first terrarium was developed by botanist Nathaniel Bagshaw Ward in 1842. Ward had an interest in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seed Disperser
In Spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living (Biotic component, biotic) vectors such as birds. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as wikt:migration, migration patterns and species interactions. There are five main modes of seed dispersal: Gravitation, gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fleshy ...

Diurnal Animal
Diurnality is a form of plant and animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which preferred pollinato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knight Anole Mating
A knight is a person granted an honorary title of knighthood by a head of state (including the Pope) or representative for service to the monarch, the church or the country, especially in a military capacity. Knighthood finds origins in the Greek ''hippeis'' and ''hoplite'' (ἱππεῖς) and Roman ''eques'' and ''centurion'' of classical antiquity. In the Early Middle Ages in Europe, knighthood was conferred upon mounted warriors. During the High Middle Ages, knighthood was considered a class of lower nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect courtly Christian warrior. Often, a knight was a vassal who served as an elite fighter or a bodyguard for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in battle on horseback. Knighthood in the Middle Ages was closely linked with horsemanship (and especially the joust) from its origins in the 12t ...

Dewlap
A dewlap is a longitudinal flap of skin or similar flesh that hangs beneath the lower jaw or neck of many vertebrates. More loosely, it can be various similar structures in the neck area, such as those caused by a double chin or the submandibular vocal sac of a frog. More generally, it can be any hanging mass of skin, such as a fold of loose skin on an elderly person's neck, or the wattle of a bird. Dewlaps can be considered as a ''caruncle'', defined as "a small, fleshy excrescence that is a normal part of an animal's anatomy". Etymology The word is first attested in the mid 1300s as ''dewelappe'' ("fold of skin that hangs from the throat of oxen and kine"), from ''lappe'' ("loose piece", from Old English ), but the first element ''*dew(e)-'' is of nebulous origin and meaning; it probably was altered by folk etymology with "dew". Old English had ''fræt-læppa'' in the aforementioned sense (and Middle English ''fresh-lappe''). There also seems to be a cognate to Danish dial ...

Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate Osteological correlates are marks on the bones of animals that are made from the causal interactions of the soft-tissue Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bo ... such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
