According to the article “Search for the Missing Sea Otters: An Ecological Detective Story” by Mary E. Allen and Mark L. Kuhlmann, the sea otter population has been decreasing at a rapid pace since the 1990’s in Aleutian, Alaska. This is demonstrated by article “What Could be the Cause of Decreasing Otter Numbers” which states that in 1997, the decline of the sea otter population had increased to about 90%. They hypothesize that the decrease in the sea otter population has been caused by their…

Recently, Betta splendens, otherwise known as bettas or Siamese fighting fish, have grown into one of the most popular ornamental fish (Monvises et al. 2009). More and more fish enthusiasts are adopting betta fish, meaning the fish are being kept in aquariums away from their evolutionarily fundamental habitats. These fish are originally from rice paddies and swampy areas in Thailand and other Southeast Asia countries (Jaroensutasinee and Jaroensutansinee 2001). Consequently, they have evolved in…

along the California coastline. Their geographic range begins in San Mateo County in northern California and extends down to Santa Barbara County in southern California. The diet of these generalist sea otters consists mainly of sluggish fishes and marine invertebrate such as sea urchins, clams, mussels, and snails, and their food resources are abundant. Current threats to southern sea otters include infectious diseases, contaminants, oil spills, fisheries interactions, predators, boat…

Charles Clover addresses the serious issue of overfishing and the impacting is having around various oceans around the world. Clover argues that the current fishing practices and illegal fishing along with the use of high tech equipments, are reducing fish stocks significantly, for larger quantities of fish are being taken out of the ocean at a rate that is impossible for fish stocks to recover in number and survive. He analyzes the situation showing how the fish crisis is affecting today and…
