Nahuatlea Obtusata
''Nahuatlea'' is a genus of flowering plants in the sunflower family, Asteraceae. It includes seven species which range from southern Texas to southern Mexico. The species which constitute genus ''Nahuatlea'' were originally placed in genus ''Gochnatia''. It was later discovered that ''Gochnatia'' was not monophyletic, and included a number of distinct clades. In 2017 Vicki Funk combined Mexican species of ''Gochnatia'' into a new genus ''Nahuatlea''. Funk concluded that the genus is a sister to the Caribbean genus ''Anastraphia'', and their common ancestor originated from South America in a dispersal event, evidenced by the fact that the Mexican ''Gochnatia'' (now ''Nahuatlea'') are more morphologically similar to the Andean members of ''Gochnatia'' than to ''Anastraphia''.

Nahuatlea Arborescens
''Nahuatlea aborescens'' is a species of tree in the Composite family endemic to the Cape region and Cerralvo Island of Baja California Sur, commonly known as ocote. It grows up to 8 meters tall, with monoecious tan-colored flowers and short, leafy branchlets. It was formerly in the genus ''Gochnatia'', where it was known commonly as the tree gochnatia. Description This plant grows in a tree habit, 3 to 8 m tall, and with a trunk 20 to 30 cm in diameter. The leaves are chartaceous (meaning resembling paper or parchment), and shaped ovate to elliptic, glabrescent (nearly smooth) on both faces. The leaf blades are 3.5 to 6.5 cm long by 2.5 to 4.5 cm wide. The leaf petiole is 5 mm long. The inflorescence is crowded at the ends of the branches. The flower heads are solitary or more usually in loose clusters of 2 to 20 at the apex of the branches, with few clusters per plant. There are 13 to 20 flowers per head, with yellowish corollas, 12 mm long. The involucre is shaped cylindri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Dispersal
Biological dispersal refers to both the movement of individuals (animals, plants, fungi, bacteria, etc.) from their birth site to their breeding site ('natal dispersal') and the movement from one breeding site to another ('breeding dispersal'). Dispersal is also used to describe the movement of propagules such as seeds and spores. Technically, dispersal is defined as any movement that has the potential to lead to gene flow. The act of dispersal involves three phases: departure, transfer, and settlement. There are different fitness costs and benefits associated with each of these phases. Through simply moving from one habitat Landscape ecology#Patch and mosaic, patch to another, the dispersal of an individual has consequences not only for individual fitness (biology), fitness, but also for population dynamics, population genetics, and species distribution. Understanding dispersal and the consequences, both for evolutionary strategies at a species level and for processes at an e ...

Andes
The Andes ( ), Andes Mountains or Andean Mountain Range (; ) are the List of longest mountain chains on Earth, longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long and wide (widest between 18th parallel south, 18°S and 20th parallel south, 20°S latitude) and has an average height of about . The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela. Along their length, the Andes are split into several ranges, separated by intermediate depression (geology), depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, Mérida, Mérida, El Alto, and La Paz. The Altiplano, Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three majo ...

Vicki Funk
Vicki Ann Funk (November 26, 1947 – October 22, 2019) was an American botanist and curator at the Smithsonian's National Museum of Natural History, known for her work on members of the composite family (Asteraceae) including collecting plants in many parts of the world, as well as her synthetic work on phylogenetics and biogeography. Biography Funk was born on November 26, 1947, in Owensboro, Kentucky, to Edwin Joseph and Betty Ann (''née'' Massenburg) Funk. She had two brothers, Edwin Jr. and Jared Kirk. She grew up in Owensboro and at a few United States Air Force bases before she was in elementary school. Funk studied biology and history at Murray State University in Kentucky and received a Bachelor of Science (BS) degree in 1969. She had wanted to attend medical school, but decided against it after volunteering at a hospital one summer. After graduating, she lived and worked part-time in Germany for two years, then returned to the United States to teach high school for ...
