Pseudomonadota is a major phylum of Gram-negative bacteria. The renaming of several prokaryote phyla in 2021, including Pseudomonadota, remains controversial among microbiologists, many of whom continue to use the earlier name Proteobacteria, of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as Escherichia, Salmonella, Vibrio, Yersinia, Legionella, and many others. Others are free-living (non-parasitic) and include many of the bacteria responsible for nitrogen fixation.
Ground beetles are a large, cosmopolitan family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily carnivorous, but some members are herbivorous or omnivorous.
The mountain beaver is a North American rodent. It is the only living member of its genus, Aplodontia, and family, Aplodontiidae. It should not be confused with true North American and Eurasian beavers, to which it is not closely related; the mountain beaver is instead more closely related to squirrels. There are seven subspecies of mountain beavers, six of which are found in California and three of which are endemic to the state.
The green and golden bell frog, also named the green bell frog, green and golden swamp frog and green frog, is a species of ground-dwelling tree frog native to eastern Australia. Despite its classification and climbing abilities, it does not live in trees and spends almost all of its time close to ground level. It can reach up to 11 cm (4.5 in) in length, making it one of Australia's largest frogs.
The swift parrot is a species of broad-tailed parrot, found only in southeastern Australia. The species breeds in Tasmania during the summer and migrates north to south eastern mainland Australia from Griffith-Warialda in New South Wales and west to Adelaide in the winter. It is a nomadic migrant, and it settles in an area only when there is food available.
The tree of life or universal tree of life is a metaphor, model and research tool used to explore the evolution of life and describe the relationships between organisms, both living and extinct, as described in a famous passage in Charles Darwin's On the Origin of Species (1859).
The affinities of all the beings of the same class have sometimes been represented by a great tree. I believe this simile largely speaks the truth.
Amphiuridae are a large family of brittle stars of the suborder Gnathophiurina. Some species are used to study echinoderm development and bioluminescence.
The Cumberland dusky salamander is a species of salamander in the family of lungless salamanders, Plethodontidae. It is endemic to the United States. Its natural habitats are temperate forests and rivers. This species is threatened by habitat loss.
Philautus abditus is a species of frog in the family Rhacophoridae. It is found in the highlands of central Vietnam as well as in extreme northeastern Cambodia. The specific name abditus is Latin for "hidden" or "concealed" and refers to the black spots on the legs that are concealed while the legs are flexed.
Meiacanthus is a genus of combtooth blennies found in the western Pacific and Indian oceans. Many species in this genus make their way into the aquarium trade and several are venomous. The genus name Meiacanthus is derived from the Greek meion meaning "less" and akantha meaning "thorn" and refers to most species having relatively few dorsal fin spines.
The upside-down harptail blenny is a species of combtooth blenny found around the Sulu Archipelago in the Philippines. This species grows to a length of 6.5 centimetres (2.6 in) TL.
Cantius is a genus of adapiform primates from the early Eocene of North America and Europe. It is extremely well represented in the fossil record in North America and has been hypothesized to be the direct ancestor of Notharctus in North America. The evolution of Cantius is characterized by a significant increase in body mass that nearly tripled in size. The earliest species were considered small-sized and weighed in around 1 kg (2.2 lb), while the later occurring species were considered medium-sized and likely weighed in around 3 kg (6.6 lb). Though significantly smaller, the fossil remains discovered of the various species of Cantius have striking similarities to that of Notharctus and Smilodectes. It is likely Cantius relied on arboreal quadrupedal locomotion, primarily running and leaping. This locomotor pattern comparable to that of extant lemurs, which has fostered the hypothesis that Cantius and other strepsirrhine adapiforms may have a close phylogenetic affinity to living lemurs.
Andinobates abditus is a species of poison dart frog, sometimes known as the Collins' poison frog. It is endemic to Ecuador where it is only known from its type locality, at the eastern base of the Reventador volcano, in the Napo Province.
Gilloblennius abditus, known commonly as the obscure triplefin, is a species of triplefin blenny in the genus Gilloblennius. It was described by Graham Stuart Hardy in 1896. It is endemic to New Zealand where it has a disjunct distribution around North and South Islands where there are highly exposed rocky coasts.
Rhysodinae is a subfamily in the family Carabidae. There are 19 genera and at least 380 described species in Rhysodinae. The group of genera making up Rhysodinae had been treated as the family Rhysodidae in the past, and subsequent DNA analysis then placed it within Carabidae, where it was sometimes treated as the tribe Rhysodini, but the most recent analyses place it as a subfamily in a clade along with subfamilies Paussinae and Siagoninae, forming a sister to the remaining Carabidae.
Neodhysores is a genus of wrinkled bark beetles in the family Carabidae, found in Southeastern Brazil. Only three specimens of this genus are known to have been found, representing these two species:
Tangarona is a genus of wrinkled bark beetles in the family Carabidae. Tangarona pensa, found in New Zealand, is the only species of this genus.
Srimara is a genus of wrinkled bark beetles in the family Carabidae. Srimara planicollis, found in Vietnam, is the only species of this genus.
Xhosores is a genus of wrinkled bark beetles in the family Carabidae. Xhosores figuratus, found in South Africa, is the only species of this genus.
Colobopsis abdita is a species of carpenter ant endemic to Guatemala. It was described by Auguste Forel in 1899.
