Results for “species”
Ichthyological terms, not general ones.
monospecific
Used in reference to a genus containing only a single species.
Mysis
Genus of mysid crustacean of which members inhabit both marine and freshwater environments. Some species are used as fish food in aquaria, and usually available frozen.

new combination
In zoological nomenclature, the first combination of a generic and previously-published specific name.
niche overlap
An overlap in resource requirements by two or more species.
nominal taxon
A nomenclatural concept denoted by an available name used in an original description, and based, actually or potentially, upon its name-bearing type but having no defined taxonomic boundaries. Often used when the precise definition of a species or genus is unclear, such as when a name may refer to more than one taxon and is therefore in need of clarification.

nominotypical taxon
Nominal, subordinate taxon within a family, genus, or species group that contains the name-bearing type taxon within that group that has been divided.
non-annual breeder
A species that lives and spawns for more than a single year
non-native
Used in reference to a species occurring, living, or growing in a region outside its natural geographic range; non-indigenous.

ovoviviparity
Reproductive strategy in which fertilisation occurs internally and the eggs develop inside the body of the mother until hatched, at which point live offspring are born. There is no placental connection between mother and embryo unlike in viviparous species.
pair
A male and a female organism of the same species. Also see breeding pair.

Palghat Gap
Also known as the 'Palakkad Gap', a low mountain pass representing the major break in the Western Ghats mountain range. The Nilgiri Hills rise to around 1100 m AMSL north of the gap and the Anaimalai Hills approximately 2000 m AMSL to the south, with average elevation within the gap 144 m AMSL. The gap has been shown to represent a biogeographic barrier restricting gene flow between populations of numerous species including Indian elephant and various birds.

peat
A compressed accumulation of partially-decomposed, chiefly vegetable matter typically found in certain marshes, bogs, and peat swamp forests throughout the world. It forms via breakdown of various plants and other organic materials in water when full decomposition is prevented due to localised acidic, anaerobic conditions. As a result of this somewhat specific nature the organisms inhabiting peaty environments are often stenotypic and found nowhere else. Peat can be used as a fuel when dried and thus has industrial importance in some countries. Also used in aquaria, especially in order to simulate blackwater habitats, either in pure, artificially-granulated or liquid extract form.
