George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

Lacertidae
The Lacertidae are the family (biology), family of the wall lizards, true lizards, or sometimes simply lacertas, which are native to Afro-Eurasia. It is a diverse family with at least 300 species in 39 genera. They represent the dominant group of reptiles found in Europe. The group includes the genus ''Lacerta (genus), Lacerta'', which contains some of the most commonly seen lizard (thus "true" lizard) species in Europe. Habitat The European and Mediterranean species of lacertids live mainly in forest and scrubland, scrub habitats. ''Eremias'' and ''Ophisops'' species replace these in the grassland and desert habitats of Asia. African species usually live in rocky, arid areas. ''Holaspis'' species are among the few arboreal lacertids, and its two species, ''Holaspis guentheri'' and ''Holaspis laevis'', are gliders (although apparently poor ones), using their broad tail and flattened body as an aerofoil.

Ryukyu Islands
The , also known as the or the , are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island. The climate of the islands ranges from humid subtropical climate (Köppen climate classification ''Cfa'') in the north to tropical rainforest climate (Köppen climate classification ''Af'') in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs. The Ōsumi and Tokara Islands, the northernmost of the islands, fall un ...

Diurnality
Diurnality is a form of plant and ethology, 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 cathemerality, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
