Alvar Nunez Cabeza de Vaca was born in 1490 at Jerez de la Frontera in Andalusia. His parents went by the name Francisco de Vera and Teresa Cabeza de Vaca. “Cabeza de Vaca means ‘head of cow’ and was derived from a peasant ancestor.” (elizabethan-era.org) “By 1528, he was appointed treasurer underneath the explorer Panfilo de Narvaez which reached what is now Tampa Bay, Florida later in the same year.” “By September of that year, all of the members of the expedition except for 60 of de Vaca’s men had died near the shore of present-day Galveston, Texas.” (Biography.com Editors). Alvar Nunez Cabeza de Vaca was a Spanish explorer who was the first historian of Texas, and one of the four survivors of the Narvaez expedition.

40 year old man presents to A&E with lip swelling. Over the next 20 minutes he develops itching of the hands and feet, increasing breathlessness and chest tightness, fall in PEFR (peak expiratory flow rate) to 200l/min, fall in BP to 80/30mmHg and Oxygen saturations are 88% on room air.

Typically, as nature starts the transformation process from summer to fall, the green leaves on the trees begin to change into colors of reds, golds, browns, and oranges. Eventually, the leaves fall off the trees onto the ground. Three factors contribute to the change in leaf color according to USDA’s Northeastern Area Forest Service website, which include leaf pigments, length of night, and weather. The increasing length of night and other ecological influences such as the temperature, rainfall, and food supply trigger the biochemical process of the leaves (na.fs.fed.us). Photosynthesis occurs in the chloroplasts of the leaves. A chloroplast is a type of plant cell organelle known as a plastid. Plastids support the storing of the needed ingredients for energy production. A chloroplast contains a green pigment called chlorophyll which is the agent that gives leaves their green color. Chlorophyll is important to the photosynthesis process as it is the chemical reaction that facilitates plants to use sunlight to produce sugars for their food (biology.about.com). During the emergent season, chlorophyll is repetitively produced and broken down, which causes the leaves to appear green in color. As the nights grow longer, the production of chlorophyll diminishes and eventually ceases production. Depending on the type of plant, as the chlorophyll becomes dormant, the color of the leaves begins to change to reds, browns, yellows, and oranges (na.fs.fed.us).

Theia Resalta or also known as Alkie, is first born of the Resalta twins. After a few months of Marcelino's death. On bright sunny day, a seven year old Alkie and his younger twin Alky are playing with Krow and Lassie, running around the backyard while laughing. Alkie got excited then run to the road Lassie followed him, Alkie being clumsy one as always, got himself trip in the middle of the road. He stands up and starts crying loud. Lassie shakes his head and run towards his little brother but froze all of the sudden as soon as he saw a car

Albino redwoods and fungi share similarities, while also differing in some traits. When it comes to the structure of both plants, albino redwoods have green and yellowish needles, a combination of normal and albino tissues, and male and female cones (http://news.nationalgeographic.com/news/2014/03/140319-redwood-albino-chimera-california-tree-tallest/), while fungi have vegetative tissues (hyphae and mycelium), reproductive bodies/structures and spores. Both fungi and albino redwoods do not contain chlorophyll, so they are dependent on other living organisms to provide them with nutrients. Fungi are described as either decomposers or saprotrophs, while albino redwoods are parasites. Albino redwoods act as parasites by stealing nutrients from

What is ‘Myrtle Rust’ and how pernicious is it? Myrtle Rust, aka Uredo rangelii, is a fungal plant pathogen native to South America that affects plants in Myrtaceae family, such as Tea tree, Beach Cherry and Bottle Brush (DAFF, 2012). Its advent can be witnessed in the form of small purple flecks and leaf spots on young leaves. It then utilizes its vicious powers to create tiny, raised spots or pustules, which turn powdery distinctive yellow after a few days. It attacks young and new plants and causes them to be stunted, leaves to be twisted and even leads to their death. While the South American trees have some resistance against this aggressor, the Australian ones are more vulnerable. It has the potential to affect up to 80 per cent of Australian native trees and the crusade cannot be stopped once it has occupied the bush lands (NSW Scientific

Phytopthora ramorum is a new pathogen that impacts over 100 plant species, mainly in California and Oregon. The pathogen has also been shipped to nurseries across the nation, but has not established itself in native forests or landscapes outside of California or Oregon. On some hosts such as plants in the oak family it causes a disease called Sudden Oak Death. Large cankers appear on bark with dark red lesions. The pathogen may also restrict flow in Xylem causing crown death, and eventually total death of the plant. The pathogen may also cause blight in other species, such as the California Bay laurel, and Rhododendron. Signs of infection are the presence of hyphae on the leaves, and chlamydospores of bark and leaves. Disease management is

On this holiday it is very special for all because this is the day when everyone celebrates the day of the Virgin of Candelaria and the kind of celebration is very cool because the Virgin of Candelaria is one of many ways in which the mother of Jesus Christ is known. According to the holy of the Catholic Church was chosen on February 2 to be out of his day, because it was when Jesus Christ was presented in the temple of Jerusalem and the purification of the Virgin Mary after childbirth, to fulfill the prescription of the Law Of the Old Testament.

The Fratercula arctica live in Northern Atlantic. In that place it is cold. The Fratercula arctica has four different species. All four are found in the cold weather. Since they live up there they have to find food. They hunt small fish. What they do is cool. The fly up to speeds to 55 miles per hour. The Fratercula arctica flap their wings 300-400 flaps in a minute. Then they swoop down and open the beak and get a lot of small fish. The stuff about 64 small fish. Since the Fratercula arctica is a bird the skin is of course feathers, so they can fly. The good thing about the Fratercula arctica is that they conservation status is good. That means the that they are not going extinct. The conservation status of a species is an indicator of the

The fungus develops in the root collar area of the tree. It travels underneath the bark by forming distinctive white mycelial fans and rhizomorphs. White mycelia fans are mats of irregular fan shaped mycelium. It grows between the wood and bark and girdles it, causing the separation between the two. The mycelia releases biopolymer degrading enzymes that allows the fungi to penetrate the bark and is used to break down the wood. The secretion of enzymes and with the separation between the wood and bark, causes the death of the tree. After decomposing, the mycelium fans leaves an impression in the resign saturated inner side of the bark.

Situated on the southernmost coast of Spain lies Andalucia, a region of hidden natural beauty. The region comprised of eight provinces has become one of the most popular travel destinations in the world. Andalucia’s natural grandeur is extraordinary by itself considering the fact that it is one of the rarest locations on earth. Andalucia is a region that provides travelers with all of the earth's treasures all in one place.

If the leaves are separated from the tree, they quickly lose their color and texture, drying up until they are brown and brittle, and die.
