According to the authors, Kraus, Brown, Caswell, Clark, Fujiwara, and Hamilton, the “North Atlantic right whale” is considered endangered animal facing killing for business purposes although the global preservation since 1935. Also, the population growth rate of the right whales has fallen since 1980. Moreover, the total number of its population nowadays seems to be getting smaller in size. Recent mortalities prove that the “North Atlantic right whale” is facing extinction. In fact, losing a…

The issue here is whether or not whaling is justifiable in today’s society, can people who are for and against whaling come together and work towards the common good? Organisations such as the International Whaling Commission which are…

The article by PHYS.ORG (2014) was written about the new dolphin species of Victoria, Australia, called the Burrunan dolphin. This species was recently discover by Dr. Kate Charlton-Robb, 3 years ago, in 2011 (PHYS.ORG, 2014). Although not a lot is known about them, there is a concern surrounding the conservation of Burrunan dolphins (PHYS.ORG, 2014). The population size of the species is very small and according to Dr. Charlton-Robb, for each region there are less than 100 dolphins that can…

The rapid spread of mercury poisoning and the increase of whaling in Eastern Asia have a very evident positive correlation. Although the whaling of large whales has seen quite a dramatic drop since the boom in the 1950’s and early 1960’s right before the Marine Mammal Protection Act was enacted in 1972, there has been a significant increase in the amount of dolphins and small whales being killed and sold in Eastern Asian Countries. One sample of Dolphin meat can contain up to 10 times the…

Exemption Question 1 Do you agree with the Norwegian and Japanese position on permitting the hunting of non-endangered species of whales as a cultural exemption? Yes, I agree that the Norwegians and Japanese have sovereignty for cultural whaling, depending on their proposed method of hunting whales. The Levin Institute (n.d.) reported that “The whales that the two countries sought to hunt were not considered endangered...”. Should Norway and Japan assume that it's open season on whales not…

Group 04 Candace Flynn (cflynn@mail.uoguelph.ca), Melissa Westaway, Katherine Znotinas, and Daniela Banda Marin 2 November 2014 Abstract Reasons for divergence within the animal kingdom is heavily debated across many orders. Macroevolution in Cetacea has been attributed to a variety of ecological and environmental dynamics which set the stage for the success of modern whales. In this meta-analysis, we investigate the magnitude of support for two current competing hypotheses explaining the…

Introduction: - Mitochondria is a double membrane organelle that is found in all eukaryotic organism. There are some evidences that proves that some of the eukaryotic organism lack this organelle but there is no true evidence which says that this specific organism completely lacks mitochondria. Mitochondria is also known as a power house of the living body cell. It stores energies in the cell and releases when its needed. Every organelle in Mitochondria have their own specific roles which helps…
