Abajo Mountains
The Abajo Mountains, sometimes referred to as the Blue Mountains, is a small mountain range west of Monticello, Utah, south of Canyonlands National Park and north of Blanding, Utah. The mountain range is located within the Manti–La Sal National Forest. The highest point within the range is Abajo Peak at . This mountain range, like both the La Sal Range and Henry Mountains in the same part of the Colorado Plateau, is formed about igneous intrusions that are relatively resistant to erosion. Some of these intrusions form laccoliths emplaced at depths of a few kilometers. The predominant igneous rock is porphyritic hornblende diorite. Ages of intrusion in the Abajo Mountains fall in the interval from 22 to 29 million years. These mountain ranges are part of the Colorado Plateau province west of the greater ranges of the Rocky Mountains The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America.

Flora Of The Rocky Mountains
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

(hardback), (paperback). pp 43 and the type species for the genus is '' Allium sativum'' which means "cultivated garlic".''Allium'' In: Index Nominum Genericorum. In: Regnum Vegetabile (see ''External links'' below). Carl Linnaeus first described the genus ''Allium'' in 1753. Some sources refer to Greek ἀλέω (aleo, to avoid) by reason of the smell of garlic. Various ''Allium'' have been cultivated from the earliest times, and about a dozen species are economically important as crops, or garden vegetables, and an increasing number of species are important as ornamental plants.

Bombus Bohemicus
''Bombus bohemicus'', also known as the gypsy's cuckoo bumblebee, is a species of socially parasitic cuckoo bumblebee found in most of Europe with the exception of the southern Iberian Peninsula and Iceland. ''B. bohemicus'' practices inquilinism, or brood parasitism, of other bumblebee species. ''B. bohemicus'' is a generalist parasite, successfully invading several species from genus ''Bombus''. The invading queen mimics the host nest's chemical signals, allowing her to assume a reproductively dominant role as well as manipulation of host worker fertility and behavior. Taxonomy and phylogeny ''B. bohemicus'' is part of the order Hymenoptera, which includes ants, bees, wasps, and sawflies, the family ''Apidae'', specific to bees, and the genus ''Bombus'', which includes all bumblebees. ''B. bohemicus'' belongs to the subgenus ''Psithyrus'', or the cuckoo bees, which includes 29 species found in Europe and the New World. Species in this subgenus are obligate parasites of other ...
