Amolops Torrentis
''Amolops torrentis'', commonly known as the torrent sucker frog or the little torrent frog is a species of frog in the family Ranidae and genus Amolops that is endemic to China, specifically only on the island of Hainan. They are most likely to be found in streams and surrounding wetland areas. Males have high-pitched mating calls, which are favored by females. Glands on this species' skin can secrete toxins. This species suffers from parasitism and habitat loss. Currently it is listed as vulnerable by the IUCN and is protected by law in China. Taxonomy ''A. torrentis'' is within the ''A. hainanensis'' group. It is a sister taxa to both ''A. hainanensis'' and ''A. daiyunnensis''. Description ''A. torrentis'' contains multiple characteristics that distinguish it from other members of the Amolops genus that also exist in China and southeast Asia. One of these differentiating characteristics is that ''A. torrentis'' has tarsal glands. A. torrentis also has a distinct tympanu ...

Malcolm Arthur Smith
Malcolm Arthur Smith (1875 in New Malden, Surrey – 1958 in Ascot) was a herpetologist and physician working in the Malay Peninsula. Early life Smith was interested in reptiles and amphibians from an early age. After completing a degree in medicine and surgery in London in 1898, he left for the then Kingdom of Siam (today Thailand) as a doctor to the British Embassy in Bangkok. In 1921 he married Eryl Glynne of Bangor, who as well as being medically trained, made significant collections of ferns from Thailand and later worked at RBG Kew. She was killed in a car crash near Bangkok in 1930. The couple had three children including the mountaineer Cymryd "Cym" Smith, also killed in a road accidenEryl was the elder sister of the mountaineer and plant pathologist Mary Dilys Glynne. Work Smith went on to become the physician in the royal court of Siam and was a close confidant and a doctor to the royal family.

Amphibians Described In 1923
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Areca
''Areca'' is a genus of 51 species of palms in the family Arecaceae, found in humid tropical forests from the islands of the Philippines, Malaysia and India, across Southeast Asia to Melanesia. The generic name ''Areca'' is derived from a name used locally on the Malabar Coast of India. Usage The best-known member of the genus is '' A. catechu'', the areca nut palm. Several species of areca nuts, known for their bitter and tangy taste, raw or dried, are routinely used for chewing, especially in combination with the leaves of betel and dried leaves of tobacco. Areca nut is also popularly referred to as betel nut because of its usage for chewing with betel leaves. In Assam, areca nut is also known as ''tamul'' in the local dialect.

Acuariidae
Acuariidae is a family of spirurian nematodes. Like all nematodes, they have neither a circulatory nor a respiratory system. They are the only family in superfamily Acuarioidea, and number about 40 genera and 300 species, most of which are parasites of birds.Hallan (2007) Genera Several genera, particularly in the Seuratiinae, are monotypic. At least some of them are liable to be invalid.

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...

Sexual Display
A courtship display is a set of display behaviors in which an animal, usually a male, attempts to attract a mate; the mate Mate choice, exercises choice, so sexual selection acts on the display. These behaviors often include ritualized movement ("dances"), vocalizations, mechanical sound production, or displays of beauty, strength, or Agonistic behaviour, agonistic ability. Male display In some species, males will perform ritualized movements to attract females. The male six-plumed bird-of-paradise (Lawes's parotia, ''Parotia lawesii'') exemplifies male courtship display with its ritualized "ballerina dance" and unique occipital and breast feathers that serve to stimulate the female visual system. In ''Drosophila subobscura,'' male courtship display is seen through the male's intricate wing scissoring patterns and rapid sidestepping. These stimulations, along with many other factors, result in subsequent copulation or rejection. In other species, males may exhibit courtship dis ...

Frog-biting Midge
Corethrellidae are a family of biting midges, small flying insects belonging to the order Diptera, females of which feed on the blood of frogs. The members of the family are sometimes known as frog-biting midges. The family currently consists of just one genus, totalling 115 extant and 10 fossil species worldwide. Most extant species are found in the lower latitudes, usually associated around the tropics. They are tiny flies with a wing length of 0.6-2.5 mm. The wing venation is similar to Culicidae (R 4 branched, M 2 branched, Cu 2 branched) with branches of Rs and M nearly parallel. R1 is, however, closer to Sc or almost midway between Sc and R2. They were, from 1962 until 1989, placed as a tribe Corethrellini within the Chaoborinae, a subfamily of Culicidae. Adult female ''Corethrella'' are attracted to the mating calls of male frogs, their chosen host taxa. As obligate external parasites, the midges feed almost exclusively on the blood of these frogs. Because of this, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitism
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
