Messor Pergandei
''Veromessor pergandei'' is a species of harvester ant native to the Southwestern United States, especially the deserts of southeastern California. It has also been identified in the Baja California peninsula of Mexico. It was first described by Gustav Mayr, who named it ''Aphaenogaster pergandei''. It can also be referred to as a black harvester ant or desert harvester ant, although these common names have also been applied to other species. Description ''V. pergandei'' has a head of equal length and width, with very large mandibles. It has short white or yellow hair and a large thorax. Males typically measure about and females about . However, individual size can vary based on factors such as availability of food and interspecific competition. The species is named after American myrmecologist Theodore Pergande. The genus was for some time synonymized under ''Messor'' but has been split out based on a 2015 study. Veromessor_pergandei-mound.jpg, nest mound Veromessor_pergandei- ...

Fauna Of The Southwestern United States
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and '' funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the " Sonoran Desert fauna" or the " Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a ...

Fauna Of California
The fauna of the U.S. state of California may be the most diverse in the United States. Of the lower 48 contiguous states, California has the greatest diversity in climate, terrain, and geology. The state's six life zones are the lower Sonoran (desert); upper Sonoran (foothill regions and some coastal lands); transition (coastal areas and moist northeastern counties); and the Canadian, Hudsonian, and Arctic zones, comprising California's highest elevations. California's diverse geography gives rise to dozens of ecosystems, each of which has its own native plants and animals. California is a huge state, the third largest in the U.S., and ranges broadly in habitats. Earth scientists typically divide California into eleven distinct geomorphic provinces with clearly defined boundaries. They are, from north to south, the Klamath Mountains, the Cascade Range, the Modoc Plateau, the Basin and Range, the Coast Ranges, the Central Valley, the Sierra Nevada, the Transverse Ranges, ...

Insects Described In 1886
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. The ...

Ambrosia Dumosa
''Ambrosia dumosa'', the burro-weed or white bursage, a North American species of plants in the family Asteraceae. It is a common constituent of the creosote-bush scrub community throughout the Mojave Desert of California, Nevada, and Utah and the Sonoran Desert of Arizona and northwestern Mexico (Baja California, Baja California Sur, Sonora, Chihuahua). ''Ambrosia dumosa'' has been studied to determine allelopathic interactions with creosote bush, ''Larrea tridentata'', which produces a chemical that inhibits the growth of ''A. dumosa.'' Other studies have suggested that ''A. dumosa'' roots produce a chemical that causes them to grow away from conspecific roots, preventing competition for water resources. In addition to burro-weed, ''A. dumosa'' is also commonly called white bursage, and burrobush. Description ''Ambrosia dumosa'' or white bursage is a form of ragweed, is a highly branched shrub 20 to 90 cm in height. The younger stems are covered with soft gray-white hai ...

Larrea Tridentata
''Larrea tridentata'', called creosote bush, greasewood, and chaparral is a medicinal herb. In Sonora, it is more commonly called ''hediondilla''; Spanish ''hediondo'' = "smelly". It is a flowering plant in the family Zygophyllaceae. The specific name ''tridentata'' refers to its three-toothed leaves. Distribution ''Larrea tridentata'' is a prominent species in the Mojave Desert, Mojave, Sonoran Desert, Sonoran, and Chihuahuan Desert, Chihuahuan Deserts of western North America, and its range includes those and other regions in portions of southeastern California, Arizona, southern Nevada, southwestern Utah, New Mexico, and Texas in the United States, and Chihuahua (state), Chihuahua, Sonora, Coahuila, Nuevo León, Zacatecas, Durango and San Luis Potosí, San Luis Potosì in Mexico.

Perennial Plant
In horticulture, the term perennial (''wikt:per-#Prefix, per-'' + ''wikt:-ennial#Suffix, -ennial'', "through the year") is used to differentiate a plant from shorter-lived annual plant, annuals and biennial plant, biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in Tree girth measurement, girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as Herbaceous plant, herbaceous perennials. However, depending on the rigours of the loca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Messor
''Messor'' is a genus of myrmicine ants with more than 100 species, all of which are harvester ants; the generic name comes from the Roman god of crops and harvest, Messor. The subterranean colonies tend to be found in open fields and near roadsides, openings are directly to the surface. Colonies can achieve huge sizes and are notable for their intricately designed granaries in which seeds are stored in dry conditions, preventing germination. The structure of ''Messor'' spp. nests is complex and the genus on the whole is one of very accomplished architects. ''Messor'' spp. are polymorphic and have a distinct caste of macrocephalic dinoergates whose role is carrying and cutting the large seeds which comprise much of the colonies' subsistence. Although they primarily feed on seeds, they occasionally eat insects and snails. Some snail shells possibly are taken into the nest because of their grain-like shape. Equipped with a tough, shining cuticle, ''Messor'' spp. are slow-movin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
