* The Mammals: A Guide to the Living Species ( 1965 ) — a comprehensive and compelling listing of all mammal genera, all non-rodent non-bat species, and additional information on select species.

The list follows McKenna and Bell's Classification of Mammals for prehistoric genera ( 1997 ) and Wozencraft ( 2005 ) in Wilson and Reeder's Mammal Species of the World for extant genera.

It is often incorrectly assumed that he insisted that the rate of change must be constant, or nearly so, but even the first edition of On the Origin of Species states that " Species of different genera and classes have not changed at the same rate, or in the same degree.

Species in the genera Allium, Hippeastrum, Narcissus, and Tulipa all have tunicate bulbs.

Species of both genera are native to the area where Greek language and culture originated, though as the word " kedros " does not seem to be derived from any of the languages of the Middle East, it has been suggested the word may originally have applied to Greek species of juniper and was later adopted for species now classified in the genus Cedrus because of the similarity of their aromatic woods.

The World Register of Marine Species places all species within the family Conidae in the genus Conus and the genera recognized by Tucker & Tenorio 2009 are considered to be " alternate representations.

Species have also been placed with the genera Catopsalis and Polymastodon Cope, 1882.

Species in both genera have been recorded joining mixed-species feeding flocks.

* Alström, Per ( 2006 ): Species concepts and their application: insights from the genera Seicercus and Phylloscopus.

Species in the Crithagra clade could conceivably be split further into several more ( sub ) genera and may well be once relationships within the clade are better resolved.

Species in the genera Tityra, Pachyramphus, Laniocera and Xenopsaris were formerly placed in this family, but evidence suggested they belong in their own family, the Tityridae, where they are now placed by SACC.

Species of Symphodus, Centrolabrus, and Labrus genera exhibit broodcare behavior.

Species in the genera Ocyptera, Alophora, and Compsilura are examples.

The World Register of Marine Species lists 44 marine genera and species named after him with the epithet nuttalli.

Species formerly included in wider views of the genus are now included in such separate genera as Fatsia, Macropanax, Oreopanax, Panax, Polyscias, Pseudopanax, Schefflera, and Tetrapanax.

Species of the genera Aspidontus and Plagiotremus ( such as the false cleanerfish ) are noted for their cunning mimicry of cleaner wrasses: by imitating the latter's colour, form and behaviour, the blennies are able to trick other fish ( or even divers ) into letting down their guard, long enough for the blennies to nip a quick mouthful of skin or scale.

Species in the genus may be referred to as " pipistrelles " or " pipistrelle bats ", though these terms are also used for species now placed in other genera, such as the western pipistrelle ( Parastrellus hesperus ) and eastern pipistrelle ( Perimyotis subflavus ) of North America.

Species in family Podocarpaceae have been reshuffled a number of times based on genetic and physiological evidence, with many species formerly assigned to genus Podocarpus now assigned to other genera.

Species and genera in the subfamily Caesalpinioideae of the family Fabaceae ( legumes ).

Species of the genera Optivus, Paratrachichthys, and Sorosichthys differ in form from other members of the family ; their bodies are more elongate.

Species of Aedes sucking blood

Species can be recognized by their rosettes of more or less folded leaves with persistent bases and quite prominent nonglandular hairs.

Species can be identified at a distance using this characteristic.

In his book Systematics and the Origin of Species ( 1942 ) he wrote that a species is not just a group of morphologically similar individuals, but a group that can breed only among themselves, excluding all others.

Species can be placed in a ranked hierarchy, starting with either domains or kingdoms.

Species of yeast found in the tea can vary, and may include: Brettanomyces bruxellensis, Candida stellata, Schizosaccharomyces pombe, Torulaspora delbrueckii and Zygosaccharomyces bailii.

Cellular necrosis can be induced by a number of external sources, including injury, infection, cancer, infarction, poisons, ROS ( Reactive Oxygen Species ), and inflammation.

Species can be restricted to one area if the border is too wide or overgrown.

Species such as the hoop pine, weeping bottlebrush, river she-oak and swamp mahogany can be found along creek banks.

On the cellular level, Species 8472's own somatic cells can become extremely virulent when in a foreign blood-stream, duplicating themselves rapidly.

Species 8472 can also survive the unprotected rigors of normal space, and appears to not need to breathe an atmosphere, or even the organic fluid present in its own realm.

The weapons of eight bioships ( referred to in Star Trek: Armada II as " Species 8472 battleships ") can be linked with that of a larger ninth bioship of modified design ( referred to in Armada II as a " Species 8472 bio-frigate "); the collective weapon thus formed can destroy an entire planet in seconds.

Species like the saltwater crocodile ( C. porosus ) can survive protracted periods of time in the sea, and can hunt prey within this environment.

She then realizes that only by working with the Federation they can defeat Species 8472.

Species in this genus can be quite different, which has led to a recent recommendation in the Bulletin of the American Museum of Natural History to split the genus, a recommendation that has been rejected ( in part ) by many taxonomists ( see Pauly et al., 2004, Evolution 58: 2517 – 2535 ; Pauly et al., 2009, Herpetologica 65: 115-128 ).

Species at higher elevations can benefit from a greater chance of inundation at the highest tides when increased water depths and marsh surface flows can penetrate into the marsh interior.

The kits contain objects that can be used to explain why an animal is endangered or to shed light on the animal's lifestyle. Some of the kits are: Conservation Kit, Endangered Species Kit, Behavioral Enrichment Kit, and Animal Diet Kit.

Species can live in the same environment, yet show very limited gene flow due to limited hybridization or hybridization yielding unfit hybrids.

Species in this genus can be found growing terrestrially in cold habitats near the snowline in the Andes and also in Costa Rica ; they are usually found close to small streams.

Species of fraudulence begin with the ascription of the various biographies to different invented ' authors ', and continue with the dedicatory epistles to Diocletian and Constantine, the quotation of fabricated documents, the citation of non-existent authorities, the invention of persons ( extending even to the subjects of some of the minor biographies ), presentation of contradictory information to confuse an issue while making a show of objectivity, deliberately false statements, and the inclusion of material which can be shown to relate to events or personages of the late 4th century rather than the period supposedly being written about.
