Ivanhoe had developed Oyu Tolgoi in Mongolia, one of the world's largest-known copper deposits.

These fangs, along with a long sleek body and large eyes, suggest Enchodus was a predatory species.

For here if anywhere in contemporary literature is a major effort to counterbalance Existentialism and restore some of its former lustre to the tarnished image of the species Man, or, as Malraux himself puts it, `` to make men conscious of the grandeur they ignore in themselves ''.

The misplaced modifier is another species more honored in the observance of obscurity than in the breach.

One species is restricted to statements which are neither explicit nor precise regarding a particular person, place, time or thing.

It seems to me that the first human being to reach one of these planets may well learn what it is to be a truly great and noble species ''.

If you really insist on knowing their names, an excellent book on the North American species is Bumblebees And Their Ways by O. E. Plath.

It is an amazing fact that in some species this will happen while the summer is still in full swing, for instance, in August.

One of my favorites is A. armata, a species very common in England, where it is sometimes referred to as the lawn bee.

Almost equal in size to a honeybee, A. armata is much more beautiful in color, at least in the female of the species: a rich, velvety, rusty red.

Its life history is much simpler than that of the truly colonial bumblebees and can serve as an example of the life cycle of many other species.

It is, however, highly suggestive and agrees well with our own findings in which we also failed to demonstrate normally occurring bronchial artery-pulmonary artery shunts in certain species, especially the dog.

Finally, it is suggested that in many respects the horse lung may be anatomically more comparable to that of the human than any other presently known species.

On chemical grounds it seems most likely that iodide is first converted to Af and then to Af as the active iodinating species.

There is a complete synonymy at the beginning of each species description.

There is Mijbil, an otter who travelled with Maxwell -- and gave Maxwell's name to a new species -- from the Tigris marshes to his London flat.

However, in contexts where " amoeboid " is defined more loosely, there are many amoeboid species that are in the Excavata clade.

The total number of known amphibian species is approximately 7, 000, of which nearly 90 % are frogs.

The numbers of species cited above follow Frost and the total number of known amphibian species is approximately 7, 000, of which nearly 90 % are frogs.

All modern amphibians are included in the subclass Lissamphibia, superorder Salientia, which is usually considered a clade, a group of species that have evolved from a common ancestor.

The suborder Neobatrachia is by far the largest group and includes the remaining families of modern frogs, including most common species.

Urodela is a name sometimes used for all the extant species of salamander.

The largest family in this group is Plethodontidae, the lungless salamanders, which includes sixty percent of all salamander species.

The colour change displayed by many species is initiated by hormones secreted by the pituitary gland.

Research into how vitamin E prevents the process of lipid peroxidation led to the identification of antioxidants as reducing agents that prevent oxidative reactions, often by scavenging reactive oxygen species before they can damage cells.

* Food safety threats ( for example, Salmonella species, E coli O157: H7, Shigella, Staphylococcus aureus )

With the exception of Entamoeba gingivalis, which lives in the mouth, and E. moshkovskii, which is frequently isolated from river and lake sediments, all Entamoeba species are found in the intestines of the animals they infect.

Entamoeba invadens is species that can cause a disease similar to E. histolytica but in reptiles.

In contrast to other species, E. invadens forms cysts in vitro in the absence of bacteria and is used as a model system to study this aspect of the life cycle.

Almost all species form cysts, the stage involved in transmission ( the exception is E. gingivalis ).

Since E. histolytica does not form cysts in vitro in the absence of bacteria, it is not possible to study the differentiation process in detail in that species.

Karl E. von Baer and Haeckel both struggled to model one of the most complex problems facing embryologists at the time: the arrangement of general and special characters during development in different species of animals.

" A sea change: exotics in the eastern Mediterranean Sea ", in: Leppäkoski, E., Gollasch, S. and Olenin, S. ( eds ), Invasive aquatic species of Europe: distribution, impacts, and management, Dordrecht ; Boston: Kluwer Academic, ISBN 1-4020-0837-6, p. 325 – 336

Professors William Emboden, Loran Anderson, and Harvard botanist Richard E. Schultes and coworkers also conducted taxonomic studies of Cannabis in the 1970s, and concluded that stable morphological differences exist that support recognition of at least three species, C. sativa, C. indica, and C. ruderalis.

The deer family has roughly 62 species ; The list is based on the studies of Randi, Mucci, Claro-Hergueta, Bonnet and Douzery ( 2001 ); Pitraa, Fickela, Meijaard, Groves ( 2004 ); Ludt, Schroeder, Rottmann and Kuehn ( 2004 ); Hernandez-Fernandez and Vrba ( 2005 ); Groves ( 2006 ); Ruiz-Garcia, M., Randi, E., Martinez-Aguero, M. and Alvarez D. ( 2007 ); Duarte, J. M. B., Gonzalez, S. and Maldonado, J. E.

Most occur in heathlands or low woodlands ; of the eastern species, B. integrifolia and B. marginata occur in forests ; many south-western species such as B. grandis, B. sphaerocarpa, B. sessilis, B. nobilis and B. dallanneyi grow as understorey plants in Jarrah ( Eucalyptus marginata ), Wandoo ( E. wandoo ) and Karri ( E. diversicolor ) forests, with B. seminuda being one of the forest trees in suitable habitat.

E. coli is the most widely studied prokaryotic model organism, and an important species in the fields of biotechnology and microbiology, where it has served as the host organism for the majority of work with recombinant DNA.

This was followed by a split of the escherichian ancestor into five species ( E. albertii, E. coli, E. fergusonii, E. hermannii and E. vulneris.

Yersinia pestis, the first described species, was identified in 1894 by A. E. J.

A hundred years later, in 1959, R. E. Moreau noted that ornithology in this period was preoccupied with the geographical distributions of various species of birds.

Work on the relationship of the number of species to area and its application in the study of island biogeography was pioneered by E. O. Wilson and Robert MacArthur.
