The family Droseraceae is a cosmopolitan species that is found on all of the continents with the exception of Antarctica. This is likely the most diverse carnivorous plant family and has 150-160 species. 11 of these species are found in the United States (Webb D. 2008). This family is usually found as an herb or rarely a small shrub. The leaves of this family are alternate or whorled. This family has simple leaves, with the lamina with glandular hairs which trap insects, or have bristles that cause the lamina to close. The stipules may be present or absent. The Stamens are as many as there are petals. The stamens may be distinct, or connate at the base. The anthers are dithecal, opening by longitudinal slits; pollen grains in …show more content…
The insects are captured by the stalked glands on the surface of the leave and are eventually covered by the sticky glands. After the prey has been dissolved by the enzymes which are secreted by the tentacles, the leaf opens and resets the trap. Another genus in the family Droseraceae is the genus Dionaea which is the genus of the Venus flytrap. The Venus flytrap has a basal rosette of leaves that are up to 20 cm across. Each of the leaves has a flat stalk that ends in a trap that is close to 2 cm across. The center of the “trap” has a reddish color and the sides of the trap have fourteen to twenty stiff bristles that interlock when the trap closes. The flowers of this plant are white and in a cluster at the tip on a 15-45 cm stalk. The flowers have five sepals and five petals. There are 15-20 stamens. The seeds are numerous and are formed in a round capsule (Rix M, Cheek M, Davis S. 2011). This genus is found in south-east United States in North and South Carolina. There are also populations recorded from New Jersey and from Florida. These two populations are thought to be exotic. The Venus flytrap is commonly grown as an ornamental due to the interesting action of it consuming insects. It is also thought that it is possible that the napthoquinons that are in the plant may have medicinal value. The family of Droseraceae is not well known for being very economically important. However,
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.
All species are found in North America and tend to be nocturnal, but they inhabit relatively unique niches, which is evident in various minute differences between the species, including fur and nose size. C. townsendii tends to live in evergreen forests that have a moderate climate while C. mexicanus lives in higher, more humid and mountainous habitats. For this reason, C. townsendii has a darker, thicker coat; not only does it act as better natural camouflage, but the coarse, thick hair protects it well from the environment. C. refenisquii is found primarily in the Southwestern United States, but migrates frequently due to the changes in

Spanish stopper (Eugenia foetida): Eugenia foetida is a member of the family Myrtaceae, the myrtle family, and is colloquially referred to as "Spanish stopper" or "boxleaf stopper." It is found year-round in the understory of mangrove forests, coastal hammocks and dunes in coastal, central to southern Florida, and east in the
Astraspis was one of the earliest fish of all time. It lacked fins and had a poorly evolved tail, making it a horrible swimmer. Its lack of fins and related lack of movement ability would have made it an easy target for Ordovician carnivores such as eurypterids and orthocones.
Venus fly traps are incredible plants, categorized in the plantae kingdom, in the droseraceae family, the Dionaea genus, and finally the Dionaea muscipula. Carnivous plants such as venus fly traps can be quite picky on their needs; such as soil, sunlight, what to feed them, and how much water they need.
The most prominent fossils in the Crato Formation are the insects that are preserved. One example of an insect that has been recently found is the Araripenymphes seldeni (as seen in figure 3), an extinct species of lacewing (Myskowiak et al., 2016). The taphonomic classification of A.seldini is: Nymphidae Family Neuroptera Order, and Insecta Class (Myskowiak et al., 2016). This particular species shows sexual dimorphism, a difference in characteristics beyond the sexual organs (Clarkson, 1998). In particular, differences in the wing colouration and wing lengths (Myskowiak et al.,
Furthermore, since the host can easily dislodge the eggs, the female will then inject a toxin that paralyzes the caterpillar or any other prey. Although, in some cases the paralysis may actually be permanent. During this the prey will lye alive, and the prey will be completely immobile with the eggs lying on its stomach. During this, the eggs will hatch, and the prey will twitch, and then the wasp larvae pierces though and begins consumption.
The life of a teenager is always unexpected and that is exactly what happened to Yajaira. Most teenagers are unaware of the consequences they will face based on their actions. The long journey Yajaira has faced shows the difference between childhood and motherhood. In the blink of an eye, life can turn around into the unexpected.
As the larva continues to grow, it starts to show a pattern of yellow, black, and white bands across its body and becomes covered in short bristles called setae. It is at this stage where the tentacles start to form. One pair grows from the abdomen and another from the thorax, or the middle section of the body. The larva gets bigger and the bands become more pronounced and the tentacles more elongated. Legs on the thorax change into a smaller pair closer toward the head and the pair at the abdomen grow larger. The caterpillar starts eating the edges of the leaves from where they were hatched and develops white spots
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.
Everyone wants designer labels. They have the finest fabrics and the most exquisite tailoring. It may sometimes seem that top of the line labels are out of reach, save for a very few. But it is not so. Every day like new or even unworn designer items are set out to be snapped up by a savvy shopper. This is just one perk of shopping at a consignment shop.
The reason behind this report is to research the impacts of the utilization of bunker fuels in the Port Adelaide River, Waterfall Gully, Johnston’s Creek, Dhaka River and its harming impact on the waterways. This report is expected to advise the South Australian government about the effect of bunker fuels on ocean acidity levels.
(The Spider Book, J.Comstock) After the innitial threads are placed, the spider will build on a catching spiral made of sticky silk. These spirals will be what capture and snare prey until the spider is able to reach it and inject it with its
