Sauromalus Varius (4)
The San Esteban chuckwalla (''Sauromalus varius''), also known as the piebald chuckwalla or pinto chuckwalla, is a species of chuckwalla belonging to the family Iguanidae endemic to San Esteban Island in the Gulf of California. It is the largest of the five species of chuckwallas, and the most threatened. Taxonomy and etymology The generic name, ''Sauromalus'', is said to be a combination of two ancient Greek words: ''sauros'' meaning "lizard" and ''omalus'' meaning "flat". The proper ancient Greek word for "flat" is however ''homalos'' (ὁμαλός) or ''homalēs'' (ὁμαλής). Its specific name ''varius'' is Latin for "speckled" in reference to the chuckwalla's mottled coloration. It was first described by American herpetologist Mary C. Dickerson in 1919. The common name chuckwalla derives from the Shoshone word ''tcaxxwal'' or Cahuilla ''caxwal'', transcribed by Spaniards as ''chacahuala''. The Seri people named originally the island for this species: ''Coftécöl li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mary Cynthia Dickerson
Mary Cynthia Dickerson (1866–1923) was an American herpetologist and the first curator of herpetology at the American Museum of Natural History, as well as the first curator in the now defunct department of Woods and Forestry. For ten years she was the editor of ''The American Museum Journal'', which was renamed ''Natural History'' during her editorship. She published two books: ''Moths and Butterflies'' (1901) and ''The Frog Book'' (1906) as well as numerous popular and scientific articles. She described over 20 species of reptiles and is commemorated in the scientific names of four lizards. Early life and career Mary Cynthia Dickerson was born in Hastings, Michigan, on March 7, 1866 to parents Wilbur and Melissa Dickerson. In her early life she cared for her three small brothers. In a memorial, Maud Slye wrote "She put herself through college at a time when it was not easy for a girl to do this." She attended the University of Michigan from 1886 to 1887 and from 1889 to 1891, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylindropuntia
''Cylindropuntia'' is a genus of cacti (family Cactaceae), containing species commonly known as chollas, native to northern Mexico and the Southwestern United States. They are known for their barbed spines that tenaciously attach to skin, fur, and clothing. Stands of cholla are called cholla gardens. Individuals within these colonies often exhibit the same DNA, as they were formerly tubercles of an original plant. Taxonomy ''Cylindropuntia'' was formerly treated as a subgenus of '' Opuntia'', but have now been separated based on their cylindrical stems (''Opuntia'' species have flattened stems) and the presence of papery epidermal sheaths on the spines (''Opuntia'' has no sheaths). A few species of mat- or clump-forming opuntioid cacti are currently placed in the genus ''Grusonia''. Collectively, opuntias, chollas, and related plants are sometimes called opuntiads. The roughly 35 species of ''Cylindropuntia'' are native to the southwestern and south-central United States, Mexic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herpetoculture
Herpetoculture is the keeping of live reptiles and amphibians in captivity (animal), captivity, whether as a hobby or as a commercial biological reproduction, breeding operation. "Herps" is an informal term for both reptiles and amphibians, shortened from the scientific umbrella term “herptiles”. It is undertaken by people of all ages and from all walks of life, including career herpetologists, professional reptile or amphibian breeders, and casual hobbyists. Etymology The origin of the word "herpetoculture" is credited to Tom Huff, who devised the word to distinguish what he, as a self-described "herpetoculturist", was doing—working to keeping reptiles and amphibians alive and healthy—from what herpetologists of that era were generally doing, namely, collecting specimens for preservation in museum collections. The word itself comes from the Greek language origin , which means "to creep". Equipment Enclosures Though traditional Aquarium, glass aquariums and Vivarium, ter ...

Bahia De Los Angeles
Bahia ( , , ; meaning "bay") is one of the 26 states of Brazil, located in the Northeast Region of the country. It is the fourth-largest Brazilian state by population (after São Paulo, Minas Gerais, and Rio de Janeiro) and the 5th-largest by area. Bahia's capital is the city of Salvador (formerly known as "Cidade do São Salvador da Bahia de Todos os Santos", literally "City of the Saint Savior of the Bay of All the Saints"), on a spit of land separating the Bay of All Saints from the Atlantic. Once a monarchial stronghold dominated by agricultural, slaving, and ranching interests, Bahia is now a predominantly working-class industrial and agricultural state. The state is home to 7% of the Brazilian population and produces 4.2% of the country's GDP. Name The name of the state derives from the earlier captaincy of Bahia de Todos os Santos, named for Bay of All Saints (' in modern Portuguese), a major feature of its coastline. The bay itself was named by the explorer Amerigo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angel Island Chuckwalla
The Angel Island chuckwalla (''Sauromalus hispidus''), also known as the spiny chuckwalla, is a species of chuckwalla lizard belonging to the family Iguanidae endemic to Isla Ángel de la Guarda (Guardian Angel Island) in the Gulf of California. The species was transported to other islands by a tribe of the Seri as a potential food source. Taxonomy and etymology The generic name, ''Sauromalus'', is said to be a combination of two ancient Greek words: ''sauros'' meaning "lizard" and ''omalus'' meaning "flat". The proper ancient Greek word for "flat" is however ''homalos'' (ὁμαλός) or ''homalēs'' (ὁμαλής). Its specific name ''hispidus'' is Latin for "coarse" or "thorny" in reference to the spines on the chuckwalla's tail. The common name chuckwalla derives from the Shoshone word ''tcaxxwal'' or Cahuilla ''caxwal'', transcribed by Spaniards as ''chacahuala''.

Island Gigantism
Island gigantism, or insular gigantism, is a biological phenomenon in which the size of an animal species isolated on an island increases dramatically in comparison to its mainland relatives. Island gigantism is one aspect of the more general "island effect" or "Foster's rule", which posits that when mainland animals colonize islands, small species tend to evolve larger bodies, and large species tend to evolve smaller bodies (insular dwarfism). This is itself one aspect of the more general phenomenon of island syndrome which describes the differences in morphology, ecology, physiology and behaviour of insular species compared to their continental counterparts. Following the arrival of humans and associated introduced predators (dogs, cats, rats, pigs), many giant as well as other island endemics have become extinct. A similar size increase, as well as increased woodiness, has been observed in some insular plants. Possible causes Large mammalian carnivores are often absent on isl ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weed
A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place", or a plant growing where it is not wanted.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. This introduces the concept of humans and their goals in a particular setting.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the aim is growing crops or pastures of a single species, or a mixture of a few desired species. In such environments, other plant species are considered undesirable and therefore a weed. Besides, some weeds have undesirable characteristics making them a plant pest in most human settings.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds.
