Lobaunia danubialis is a species of minute freshwater spring snails, aquatic gastropod mollusks or micromollusks in the family Hydrobiidae.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
Epipactis, or helleborine, is a genus of terrestrial orchids consisting of approximately 70 species. This genus is abbreviated as Epcts in horticultural trade.
The whitebeams are members of the family Rosaceae, comprising subgenus Aria of genus Sorbus, and hybrids involving species of this subgenus and members of subgenera Sorbus, Torminaria and Chamaemespilus. They are deciduous trees with simple or lobed leaves, arranged alternately. They are related to the rowans, and many of the endemic restricted-range apomictic microspecies of whitebeam in Europe are thought to derive from hybrids between S. aria and the European rowan S. aucuparia; some are also thought to be hybrids with the wild service tree S. torminalis, notably the service tree of Fontainebleau Sorbus latifolia in French woodlands.
Chamaecytisus is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae. It may be a synonym of Cytisus. C. palmensis is a tree from the Canary Islands used as a fodder crop around the world.
The aperture is an opening in certain kinds of mollusc shells: it is the main opening of the shell, where the head-foot part of the body of the animal emerges for locomotion, feeding, etc.
Fraxinus angustifolia, the narrow-leaved ash, is a species of Fraxinus native to central and southern Europe, northwest Africa, and southwest Asia.
Theodoxus danubialis is a species of small freshwater snail with an operculum, an aquatic gastropod mollusk in the family Neritidae, the nerites. The species is considered as endangered in Germany, Austria and in the Czech Republic.
Theodoxus fluviatilis, common name the river nerite, is a species of small freshwater and brackish water snail with a gill and an operculum, an aquatic gastropod mollusk in the family Neritidae, the nerites.
Lobaunia is a genus of minute freshwater spring snails, aquatic gastropod mollusks or micromollusks in the family Hydrobiidae.
Proasellus is a genus of isopod crustaceans in the family Asellidae. Two of its species, P. parvulus and P. slovenicus, are Slovenian endemics which are listed as vulnerable species on the IUCN Red List.
Trochulus striolatus, previously known as Trichia striolata, common name the "strawberry snail," is a species of small, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Hygromiidae.
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.
Theodoxus prevostianus is a species of small freshwater snail with an operculum, an aquatic gastropod mollusk in the family Neritidae, the nerites.
Hydrachna is a genus of mites in the family Hydrachnidae, the sole genus of the family. There are more than 80 described species in Hydrachna.
