Taxonomic Importance Of Trichomes

The only organism in the included area is the termite so that is the common name for the class reticulitermes.

Peyote was originally described in 1560, however it was not until the middle of the nineteenth century that botanists were able to conduct field research and correctly classify the cactus (Anderson, 1980). Field studies have concluded that there are two distinct populations of peyote which represent two species. The first and most common, Lophophora williamsii extends from southern Texas reaching south to the Mexican state of San Luis Potosi. The second and least common of the two species is Lophophora difusa, which occurs in the dryer terrain of the Mexican state of Queretaro. This species differs from the more common species by, "being yellowish-green rather than blue green in color, by lacking any

The nine specimens were placed into a watch-glass container and checked to ensure that they were of relatively equal sizes to one another. The pipette was then utilized to collect one Daphnia magna and placed onto a depression slide to create a wet mount. It is noted that a coverslip was not to be placed on the top of the slide.

When choosing a level of identification, taxonomic sufficiency is an important concept to consider. Benthos must be identified to a level that will reliably asses biological condition and recognize ecological patterns. Finding the balance between getting an accurate representation of a biological community and the accuracy of identifications involves consideration of time and financial constraints as well as the expertise required.

There are twelve species within the same genus and have subtle variations in physical appearances, all living in freshwater, but due

Purple Loosestrife (Lythrum salicaria), is a plant native to Europe, Eastern Australia, Asia and Northern Africa. Through history, this plant has been used as a medical herb for the treatment of dysentery, bleeding, wounds, ulcers and sores. The introduction of the Purple Loosestrife, through shipping, has caused disruption of waterflow and the crowding out of native species. Each individual Loosestrife plant can produce up to 2.7 millions seeds , this has helped it overtake native species, such as the cattail. Very costly and difficult to remove, Purple Loosestrife numbers show no sign of decreasing. The Water Chestnut (Trapa natans L.), is an aquatic plant species native to Europe. Introduced much like the Purple Loosestrife, the Water Chestnut is a plant that thrives in shallow depths of rivers and lakes, but can spread to deeper waters. Due to the coverage and over population of the Water Chestnuts, navigation, livable habitat and recreational activities are all affected by the plant. The beds of Water Chestnut also provide a perfect breeding ground for

Originating from eastern and southern United States, phylloxera lives on native American vines. Developing on mature storage roots, phylloxera disrupts their function, allowing countless secondary fungal pathogens to be introduced. Early signs of a phylloxera infestation include yellowing of leaves and stunting of growth as the leaves lose function. Symptoms will appear within three years, ultimately killing the vines between five to six years depending on the phylloxera genotype. Phylloxera is characterized by having three-jointed antennae, the third of which is the longest, and its overlapping wings resting flat on the back. It belongs to the order of Homoptera, and shares commonalities between two families of that sub-order: the plant-lice and bark-lice. Their lifecycle, from egg to adult, is gradual and complex—one species is known to progress through 21 different phases. Phylloxera adults are all female and reproduce asexually. One adult female is capable of producing 1) 200 eggs per cycle and 2) having several cycles in a lifetime.

On August 28, 2014, my family and I went to Washington Crossing State Park. The park section where we stayed was 74.862940 degrees south (Longitude) and 40.313780 degrees east (Latitude). We went there at 2:20 PM and returned at 3:51 PM. The objectives of my observation was to clearly identify the energy flow in the environment while observing the flora and fauna of the area. The temperature for the past few days was around 85 to 90 degrees Fahrenheit and it was mostly sunny. The temperature when I went to the park was 78 degrees Fahrenheit which was slightly cooler than usual. The heat might have caused some animals to stay in their

This online article provides useful information concerning the major classifications of nymphs. It clearly explains the two general groups nymphs can be divided into and thus provides insight into more basic knowledge about nymphs. This article on Tribunes and Triumphs sums up smaller divisions of nymphs as well. Although this article went abnormally in depth concerning nymph classification, the overall idea expressed in the article provided useful information,

Warty Jumping-Slugs are around 20 mm when fully grown. They have a noticeable hump on their back (mantle); it is a flat shell that is almost covered by their skin. The slugs have a greyish, brownish body with dark patches, and dark blue eye stocks (tentacles). The name “Jumping-Slug” comes from the way they “jump” or “flop around” when irritated.

Although only about half of the Lucilia species listed as valid by Aubertin (1933) were included, these results strongly suggest that L. sericata and L. cuprina are indeed sister species. All of the Bayesian inference analyses (Figs 1–3) indicate that L. sericata and L. cuprina are sister taxa with strong support from the nuclear gene (28S & Per) and total data (28S, Per & COI) trees and weaker support from the COI gene alone. Lucilia cuprina is paraphyletic (Fig. 2) with respect to L. sericata in the mitochondrial gene (COI) tree, as has been shown previously (using the same sequences but weaker auxiliary taxon sampling) to be the result of introgressive hybridisation between these two species (Williams & Villet, 2013). In another study, the nuclear gene elongation factor-1 alpha (EF-1α) did not recover L. sericata and L. cuprina as sister-species (McDonagh & Stevens, 2011), but the clade containing L. sericata was poorly resolved and thus the conclusion was not well supported. In the same study, the 28S and COI gene trees both recovered L. sericata and L. cuprina as sister species with strong support (McDonagh & Stevens, 2011).

The common photobiont genus is Trebouxia (Parmotrema, n.d.), which is a commonly referred to as green algae (Trebouxia, n.d.). This means that the photobiont of Parmotrema dilatatum is a uni-celled species of green algae. The mycobiont, or the fungal partner within the lichen, of P. dilatatum is unknown. The photobiont of lichen is essential because without it the mycobiont would not be able to use any of the photosynthetic produced food. But, the mycobiont of P. dilatatum is just as important because it provides protection and an anchor to the photobiont. This is a symbiotic relationship, or where both the photobiont and mycobiont benefit from living and interacting with each

The report states that, when seen under light microscopy it is revealed that Harmonia carries abundant amount of obligate parasitic microsporidia in its blood stream. This parasitic microsporidia replicates inside the cell after

The Adansonia digitata is primarily found within the semiarid lands of Africa, and precisely within the tropical region. However, it is still a possibility to find the species other varied ecosystems such as the coastal areas. However, the species is very rare to find after approaching the desert lands. A conspicuous notification about the

Lotus japonicus is one of the important model leguminous plant to study the interaction and compatibility of plant parasitic nematode to cause infection (Lohar & Bird, 2003).
