A group of individuals agreeing in common attributes, and designated by a common name; a conception subordinated to another conception, called a genus, or generic conception, from which it differs in containing or comprehending more attributes, and extending to fewer individuals. Thus, man is a species, under animal as a genus; and man, in its turn, may be regarded as a genus with respect to European, American, or the like, as species.

In science, a more or less permanent group of existing things or beings, associated according to attributes, or properties determined by scientific observation.

A sort; a kind; a variety; as, a species of low cunning; a species of generosity; a species of cloth.

An officinal mixture or compound powder of any kind; esp., one used for making an aromatic tea or tisane; a tea mixture.

A group of living things that appear to have common ancestry so closely related that their characteristics definitely separate them all from any other group; a further division of a genus.

n. (L. species, particular kind) a group of interbreeding individuals, not interbreeding with another such group, being a taxonomic unit including two names in binomial nomenclature, the generic name and specific epithet, similar and related species being grouped into a genus.

A group of organisms that differ from all other groups of organisms and that are capable of breeding and producing fertile offspring. This is the smallest unit of classification for plants and animals.

A group of closely related plants under the same Genus.

The lowest group of creatures in the tree of life. The hierarchy is as follows: Kingdom; Phylum; Class; Order; Family; Genus; Species. The species is the group of creatures which share a great number of similarities and share a common name with other groups.

a group of animals or plants of the same kind ....... back

A group of organisms (individuals) that can interbreed and reproduce with each other. Used to distinguish sexually reproducing organisms into groups. Individuals from two different species cannot have offspring. They are said to be reproductively isolated. The biologist Ernst Mayr formulated this definition of a species advancing our understanding of the mechanism of evolution of higher organisms. For microbes, the species definition does not properly apply, because they do not reproduce sexually, but have an efficient mechanism to exchange genetic material even between evolutionarily distant forms. This exchange of genes is known as horizontal gene transfer. Unlike sexual reproduction, it usually involves only a fraction of an organisms genome that is being transferred and is a mechanisms of increasing genetic variability among microorganisms that does not depend on cellular reproduction (cell division).

The scientific name of a plant; the genus name and the specific epithet together; also equal to the latin name or binomial

A reproductively isolated aggregate of interbreeding organisms.

In chemistry, a distinct kind of molecule, ion, or other structure.

Groups of actually (or potentially) interbreeding natural populations that are reproductively isolated from other such groups. Reproductive isolation implies that interbreeding between individuals of two species normally is prevented by intrinsic factors.

In biological systematics, group of organisms of common ancestry that are able to reproduce only among themselves and that are usually geographically distinct. See NT chemical species.

group of living things that share many common traits. Each species is different from every other species in one or more ways.

Term used to describe the group of like individuals. Classically species were defined as organisms that share certain characteristics.

kind or sort

a group of animals or plants that have one or more characteristics in common .............. back

A certain type of plant or animal

The division of animal classification below Genus. A group of animals having common attributes, designated by a common name, that has the same structure, and that can breed together.

a group of organisms that are very much alike and reproduce in their natural environment. We belong to the human species.

A cohesive historical lineage of ancestral-descendant populations of organisms that maintains its identity from other such lineages. A species comes into being at a branching event (when one lineage becomes one or more lineages), and ceases to exist either at a branching event (when it gives rise to new species) or when the lineage is terminated through extinction.

A group of animals or plants, whose members breed naturally only with each other.

a single kind of organism; white-tail and mule are different species of deer

more information for scientifically naming a plant. The species name follows the genus. Caesalpinia (genus) pulcherrima (species). Red bird-of-paradise (common name).

Level of taxonomy below Genus. The second part of a bird's scientific name is the species name. The species name is never capitalized.

a group of similar individuals that can breed among themselves. A biological category used to classify organisms.

A group of plants or animals that are uniquely distinguished from others, sharing various characteristics, and usually that are able to reproduce. Species are often broken down into additional subcategories, such as sub-species or varieties.

One of the major classifying categories of taxonomy, representing divisions of a genus, and sometimes further classified into subspecies.

Used when naming plants. Designates a specific species of the 'Genus' and is best described as the plant worlds equivalent to our Christian names (or first names). Will follow the Genus name and is usually in Latin. Note: Once a plants full name is used, i.e. Hedera helix, future listings will abbreviate the Genus name and follow it with the species name. An example would be, H. helix, as the next plant in a listing.

group of organisms which interbreed and are reproductively isolated from all other such groups.

The basic unit of taxonomic classification, designating a group of closely related individuals that are capable of interbreeding.

A group of organisms defined by their ability to interbreed with only each other.

A segment of a population-level lineage that is evolving separately from other such lineage segments as indicated by one or more lines of evidence (e.g., distinguishability, reproductive isolation, monophyly, etc.).

the most specific taxonomic classification; an interbreeding population of individual organisms; often abbreviated as 'sp.' in reference to a single species or 'spp.' when referencing several species

The fundamental biological classification consisting of very similar plants or animals.

genetically distinct population(s) that interbreed but are reproductively isolated from other such groups.

a group of individuals that share features and are able to interbreed under natural conditions to yield fertile offspring.

a group of populations capable of successfully interbreeding and reproductively isolated from other such populations (The White-tailed Deer is a common species of mammal found in the Pinelands.)

A biological type; on MSDSs, species refers to the test animals -- usually rats, mice, or rabbits -- which were used to obtain the toxicity test data reported.

A class of individuals having common attributes and designated by a common name; a category of biological classification ranking immediately below the genus or subgenus; comprising related organisms or populations potentially capable of interbreeding.

1. Freely interbreeding population of organisms. The organisms in a species usually share a large number of characters. Their offspring are fertile. (Some species can interbreed, but their offspring are infertile.) 2. Generally the lowest level in a taxonomy. A category of animals or plants below a genus. Sometimes breed is specified below it, such as for cultivated plants.

A group of organisms that are closely related

a taxonomic category of individuals or populations capable of breeding among themselves, but not usually with other individual or populations

A group of organisms with many common characteristics; a collection of closely related strains sufficiently different from all other strains to be recognized as a distinct unit.

Animals, plants or micro-organisms that are so similar that they are able to have offspring.

Group of similar individuals having a number of correlated characteristics and sharing a common gene pool. The species is the basic unit of taxonomy on which the binomial system has been established. The scientific name of a plant or animal gives the genus first and then the species as in Abies (genus) grandis (species). Species is both the singular and plural form of the word.

groups or individuals of closely connected plants within a genus.

a natural population that can breed and produce fertile offspring.

A distinct population that tends, in nature, not to mix reproductively with other populations.

a group of organisms that can breed or produce offspring

Taxonomic designation for the unique name of a living organism.

A group of individuals of common ancestry that closely resemble each other structurally and physiologically and that can interbreed, producing fertile offspring.

Part of the plant classification system. This is used to describe closely related plants. See also genus and family.

A class of individuals having some common characteristics or qualities.

The taxonomic unit (the most specific taxonomic category). It designates individuals with similar morphologic structures, who can reproduce with each other.

a particular kind of plant or animal; all members of a species share certain characteristics and are known by a specific name. A subspecies is a division of a species.

It is hard to define a species absolutely because the process of one species becoming two or changing into another species is so slow that there is no point at which one can say 'Now! It's a different species from yesterday!'. The most simple definition is a group of organisms that can breed together to produce fertile offspring. Species are the smallest unit of biological taxonomy, and are grouped together with similar species to form a genus.

The name given to a single kind of organism. Species can be divided into sub-species.

a group of interbreeding organisms that can produce offspring with the capacity for viable reproduction.

the smallest unit in biological classification. Members of the same species are able to breed among themselves successfully. Similar species are grouped within one genus.

A group of individuals with certain common characteristics

A group of individuals or populations that are similar in structure and physiology and are capable of interbreeding and producing fertile offspring. Separate species typically are different in structure and/or physiology from each other and normally do not interbreed. A species name is the second word of a scientific name and is not capitalized.

Living things such as plants and animals.
