Southern Andean Yungas
The Southern Andean Yungas is a tropical and subtropical moist broadleaf forest ecoregion in the Yungas of southwestern Bolivia and northwestern Argentina. Geography The ecoregion occurs along the eastern slope of the Andes from southern Bolivia into northern Argentina, at elevations ranging from . In the lowlands to the east the Yungas transition to the semi-arid Dry Chaco. To the northwest they are bounded by the Bolivian montane dry forests, and by the high-elevation Central Andean puna and High Monte grasslands to the west. Climate This ecoregion has a subtropical highland climate. The climate is influenced by trade winds from the east that bring up to of rain per year. There is a dry season from April to October, and occasional snowfall at higher elevations during the winter months.Malizia, L.; Pacheco, S.; Blundo, C.; Brown, A.D.

Mesic Habitat
In ecology, a mesic habitat is a type of habitat with a moderate or well-balanced supply of moisture, e.g., a mesic forest, a temperate hardwood forest, or dry-mesic prairie. Mesic habitats transition to xeric shrublands in a non-linear fashion, which is evidence of a threshold. Mesic is one of a triad of terms used to describe the amount of water in a habitat. The others are xeric and hydric. Further examples of mesic habitats include streamsides, wet meadows, springs, seeps, irrigated fields, and high elevation habitats. These habitats effectively provide drought insurance as land at higher elevations warms due to seasonal or other change. Healthy mesic habitats act like sponges in that they store water in such a way that it can be deposited to neighboring habitats as needed. They are common in dryer regions of the western United States, and can be a good water source to neighboring desert habitats. Healthy mesic habitats also provide forb and insects for organisms belonging t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Myrtaceae
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciation; i ...

Allophylus Edulis
''Allophylus edulis'' ( pt, chal-chal) is a plant species in the genus ''Allophylus'' endemic to the Guianas, Brazil, Bolivia, Paraguay, Argentina and Uruguay. Phytochemistry Quebrachitol, a cyclitol, and viridiflorol, a sesquiterpenoid Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many unique combinations. Biochemical modificati ..., are found in ''A. edulis''. Vernacular names This plant has several different common names. In Paraguay it's called ''kokû'', with a nasal ending. In Argentina, the common name is ''chal-chal'' (hence Los Chalchaleros, a folkloric music group), as in Portuguese.

Boraginaceae
Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system it was included in Lamiales, but it is now clear that it is no more similar to the other families in this order than they are to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae in eleven distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petiol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cordia
''Cordia'' is a genus of flowering plants in the borage family, Boraginaceae. It contains about 300 species of shrubs and trees, that are found worldwide, mostly in warmer regions. Many of the species are commonly called manjack, while ''bocote'' may refer to several Central American species in Spanish. The generic name honours German botanist and pharmacist Valerius Cordus (1515–1544). Like most other Boraginaceae, the majority have trichomes (hairs) on the leaves. Taxonomy The taxonomy of ''Cordia'' is complex and controversial. Gottschling et al. (2005) say this is partly due to "extraordinarily high intraspecific variability" in some groups of species, making identification difficult, and partly due to new taxa having been "airily described on the basis of poorly preserved herbarium specimens". Selected species *''Cordia africana'' Lam. – White manjack *''Cordia alliodora'' ( Ruiz & Pav.) Oken – Spanish elm, Ecuador laurel, salmwood, bocote (Neotropics) *''Cordia bo ...

Euphorbiaceae
Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of a genus in the family. Most spurges, such as ''Euphorbia paralias'', are herbs, but some, especially in the tropics, are shrubs or trees, such as ''Hevea brasiliensis''. Some, such as ''Euphorbia canariensis'', are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution. The greatest diversity of species is in the tropics, however, the Euphorbiaceae also have many species in nontropical areas of all continents except Antarctica. Description The leaves are alternate, seldom opposite, with stipules. They are mainly simple, but where compound, are always palmate, never pinnate. Stipules may be reduced to hairs, glands, or spines, or in succulent species are sometimes absent. The plants can be monoecious or dioecious. The radially symmetrical flowers are unisexual, w ...

Lauraceae
Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as ''Sassafras'', are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus ''Cassytha'' is unique in the Lauraceae in that its members are parasitic vines. Most laurels are highly-poisonous. Overview The family has a worldwide distribution in tropical and warm climates. The Lauraceae are important components of tropical forests ranging from low-lying to montane. In several forested regions, Lauraceae are among the top five families in terms of the number of species present. The Lauraceae give their name to habitats know ...
