Most of the known rhino species are West African.
Specialized species like Mastodon americanus have completely lost the rudimentary premolars.
Buffalo are a different species – like the water buffalo.
In size the male African elephant often surpasses the Asiatic species, reaching nearly 12 ft.
Some species show fermentative power.
Why has man just these species of animals for his neighbors; as if nothing but a mouse could have filled this crevice?
The 2000s saw the rise of commercially viable seeds created by transgenesis, that is, the insertion of DNA from one species into another species.
Allied to the pine-grosbeak are a number of species of smaller size, but its equals in beauty of plumage.'
The African elephant is a very different animal from its Asiatic cousin, both as regards structure and habits; and were it not for the existence of intermediate extinct species, might well be regarded as the representative of a distinct genus.
In 1894 and 1895, Fischer, in a remarkable series of papers on the influence of molecular structure upon the action of the enzyme, showed that various species of yeast behave very differently towards solutions of sugars.
Unlike the African species, the Indian elephant charges with its trunk curled up, and consequently in silence.
It is now filled with the smooth sumach (Rhus glabra), and one of the earliest species of goldenrod (Solidago stricta) grows there luxuriantly.
Finally, we get to the fourth order of GMO: being able to splice genes from one species into another species, a process known as transgenesis.
I thought I might just as well describe my pet in order to know it--order, vertebrate; division, quadruped; class, mammalia; genus, felinus; species, cat; individual, Tabby.
Schwann in 1839) was studied by Hansen, who found that each species only developed spores between certain definite temperatures.
Amongst hardy species of Nymphaea now much grown are candida, nitida, odorata, pygmaea and tuberosa, all with white, more or less sweet-scented flowers; flava, yellow, and sphaerocarpa, rose-carmine.
Throughout Britain, as a rule, this species is one of the most plentiful birds, and is found at all seasons of the year.
By their describers, the dwarf European elephants were regarded as distinct species, under the names of Elephas melitensis, E.
In this connexion it is of interest to note that, both in the Mediterranean islands and in West Africa, dwarf elephants of the African type are accompanied by pigmy species of hippopotamus, although we have not yet evidence to show that in Africa the two animals occupy actually the same area.
Tubulifera: This division comprises but a single family - the Phloeothripidae; the species are not numerous, but some of them are of large size for Thysanoptera, as much as 8 mm.
Still, the close relationship of the existing Liberian pigmy hippopotamus to the fossil Mediterranean species is significant, in relation to the foregoing observations on the elephant.
Many species of Thysanoptera are known to be habitually parthenogenetic. The eggs are laid on the food-plant, those females possessed of an ovipositor cutting through the epidermis and placing their eggs singly within the plant-tissues; a single female may take five or six weeks to deposit all her eggs.
In C. nigrescens and in some other species a zooid may contain a pair of ovaries, a pair of testes, or an ovary and a testis, although the males, females and hermaj phrodites do not differ from one another in external characters.
While the majority of the Thysanoptera are thus vegetarian in their diet, and are frequently injurious in farm and garden, some species, at least occasionally, adopt a predaceous habit, killing aphids and small mites (so-called "red-spiders") and sucking their juices.
The minute insects included in it, which haunt blossoms and leaves, are fairly well known to gardeners by the name Thrips, a generic term used by Linnaeus for the four species of the group which he had examined and relegated to the order Hemiptera.
If, on the other hand, the dwarf Congo elephant be regarded as a species, then the Maltese and Cyprian elephants may have to be classed as races of Elephas pumilio; or, rather, E.
Previously to Hansen's work the only way of differentiating I Hansen found there were three species of spore-bearing Saccharomycetes and that these could be subdivided into varieties.
Hansen showed that the microscopic appearance of film cells of the same species of Saccharomycetes varies according to the temperature of growth; the limiting temperatures of film formation, as well as the time of its appearance for the different species, also vary.
In the zymo-technical industries the various species of yeast exhibit different actions during fermentations.
WATER-LILY, a name somewhat vaguely given to almost any floating plant with conspicuous flowers, but applying more especially to the species of Nymphaea, Nuphar, and other members of the order Nymphaeaceae.
The usual variations in habit that characterize plant-feeding insects are exhibited by the Thysanoptera some species being found only on one particular food-plant, while others thrive indifferently on a large assortment.
Nests of this species were found in 1821 by Johana Wilhelm Zetterstedt near Juckasj,rwi in Swedish Lapland, but little was known concerning its nidification until 1855, when John Wolley, after two years' ineffectual search, succeeded in obtaining near the Finnish village Muonioniska, on the Swedish frontier, well-authenticated specimens with the eggs, both of which are like exaggerated bullfinches'.
It is represented in the south-west of North America by other forms that by some writers are deemed species, and in the northern parts of South America by the C. phoeniceus, which would really seem entitled to distinction.
In this respect the Asiatic species differs very widely from its African relative, whose nutriment is largely composed of boughs and roots.
Endospore formation, the conditions for which are as follows: (1) suitable temperature, (2) presence of air, (3) presence of moisture, (4) young and vigorous cells, (5) a food supply in the case of one species at least is necessary, and is in no case prejudicial.
The food of this species seems to consist of the seeds and buds of many sorts of trees, though the staple may very possibly be those of some kind of pine.
