degrees F. Its paws have soles on the insides for additional insulation and to help it walk on the ice. The arctic fox preys on any small creatures such as: lemmings, voles, ringed seal pups, fish, waterfowl, and seabirds. It also eats small invertebrates, seaweed, and insects. Arctic foxes form monogamous pairs during the breeding season and they stay together to raise their young in underground dens. Arctic foxes do not hibernate, and are active all year-round. They build up their…

functional SMN protein using antisense oligonucleotide drugs (nusinersen). These are short sequences of RNA that attach to mRNA preventing the gene from producing the protein (Definition of Antisense Drug; Wertz and Sahin 5-19). With the aid of mice, invertebrates, larger animals and in vitro human SMA stem-cell models, scientists are attempting to discover a treatment method with minimum complications (Wertz and Sahin 5-19). A specific clinical trial experience involves the nusinersen drug…

of those creatures include...rabbits and hares, rats and mice, and voles, although it freely hunts any animal it can overtake, primarily other rodents and small mammals, but also larger mid-sized mammals, various birds,reptiles, amphibians and invertebrates. In ornithological study, the great horned owl is often compared to the Eurasian eagle owl, a closely related species which, despite the latter's notably larger size, occupies the same ecological niche in Eurasia, and the red-tailed hawk,…

The decline in bees has been a controversial topic that has gradually garnered public attention over the last few years. With nearly 87% of all flowering plants (Ollerton, et al. 321), and 35% of global crop production (Klatt, et al.) being reliant on animal pollination, bees are a vital contributor to food production. Unfortunately, the bee population has been dropping steadily for the last 60 years due to factors such as, pesticides, invasion of pests, and climate change (Walters 375).…

Depriving California Seals of their Home In the article “Harbor Seals in the Children’s Pool,” the author writes about different opinions for keeping harbor seals in the children pool or chasing them away. The author gives examples of people who agree to keep the seals the seals and their reasons, and other who don’t agree and their sights and aspects. The author shows us the two sides of the issue as positive and negative effects of keeping the children’s Beach as a rookery for California…

to take every step we can to prevent them from spreading further and endangering our ecosystems.According to Ontario’s invasive species awareness website, plants (both aquatic and terrestrial), fish, forest pests (E.G. the emerald ash borer), invertebrates, and pathogens are all invasive species found in Ontario. They also state that over 185 invasive species are currently living in the great lakes.…

Within the past several decades, the zebra mussel Dreissena polymorpha has made its way to the top of the list as one of the most destructive invasive species in the North American water systems. While many studies have been made focusing on the ecological impact of zebra mussels, little is known about the geographical history of their invasions and patterns of genetic differentiation among and within populations in their native and invaded ranges (May, Gelembiuk, Panov, Orlova, & Lee, 2006).…

Juvenile summer flounders eat small shrimp and other small crustaceans. Adult summer flounders eat small winter flounder, menhaden, sand lace, red hake, silversides, bluefish, weakfish and mummichogs. They also eat invertebrates such as squid, opossum shrimp, mollusks, blue cram and sand shrimp. Adults attack very often and are very hard to steer clear from. Generally, adult summer flounders chase schools of fish until they catch a couple. They typically chase the school…

All animals belong to the supergroup Unikonta. Since these animals are found in almost every environment on earth, it has become possible to study their characteristics and construct evolutionary relationships, noting morphological and molecular similarities and differences. The relationships between the most primitive of animals were determined by the morphological traits of symmetry, tissues, body cavity, embryological development, and molecular evidence. [1] Symmetry and tissues are major…

Crown-of-thorns Starfish or COTS are marine invertebrates that are responsible for approximately 42 percent of the loss of coral on Australia’s Great Barrier Reef (Cranston, 2015). Plagues of this starfish have destructed coral reefs world wide. Scientists have identified fossil evidence dating back to millions of years ago, however outbreaks have only been detected in the last 50 years (Cranston, 2015). They are characterised by their venomous thorns and are capable of piercing through…
