Decline of Killer Whales

Killer whales are divided into two classes: the residents and the transients. The central differences between these two types involves their general behavior and diet. Transient groups feed mainly on marine mammals, while resident pods eat mainly fish. Unlike resident killer whales, which travel in large, extended family groups, the transients keep their group sizes small.

Critical Status of the Brown Bear

Tourists visit Alaska with visions of postcard-perfect wildlife and scenery dancing through their heads. They expect to see brown bears plucking salmon out of the beautiful and majestic Kenai River. The problem with this vision is the possible decline of brown bears on the Kenai Peninsula in the not-to-distant future.

Connectivity and Systemic Resilience of the Great Barrier Reef

Marine ecosystems are characterised by high levels of larval connectivity among populations linked by ocean or coastal currents [1]. Ensuring functioning and resilient ecosystems requires that processes of connectivity are maintained, particularly when the metapopulation has been widely depleted and individual patches must recolonise from neighbours [2].

Jellyfish Apocalypse: Problems, Causes and Opportunities

When does the future start with regards to the ocean? Rising sea levels, ocean acidification, and overfishing are problems that the ocean faces right now. An ocean full of jellyfish is a probable future. Jellyfish can be very beautiful with their movements and bioluminescence and have an interesting life cycle.

Climate Change

Climate change is a long-term significant change in the weather patters of a geographical area, or in the case, the world’s oceans. Climate change can be natural or caused by changes people have made to the land or atmosphere. It has become perhaps the most complicated issue facing world leaders.

Petersburg’s Resilience to a Tsunami

Tsunamis have a history in Southeast Alaska, whether caused by earthquakes, landslides, or both. These natural disasters have been cited in many cultural tales of Southeast Alaska.

Arsenic Contamination from Water

The results demonstrate that the uncoated, or bare, magnetite nanoparticles were the most effective in the removal of arsenic from the water, when compared to the results of the nanoparticles with the humic acid and oleic acid surfactants.

Eco-Friendly Method for Developing Plastics

The purpose of the project is to determine the effects of catalysts on the depolymerization of chitin using ionic liquids.

Smart Flood Sensor: Predicting Water Accumulation

The researcher developed a Smart Flood sensor that can not only help identify drain openings that are getting clogged in real-time, but can also determine areas where more drain pipes are needed.

Antarctica and the Strategic Plan for Biodiversity

The Convention on Biological Diversity (CBD) is an international agreement established to sustain the diversity of life on Earth. In 2010, following assessments showing that over the previous decade the state of global biodiversity continued to decline [1], the Strategic Plan for Biodiversity 2011–2020 [2] (hereafter the Strategic Plan) was developed under the aegis of the CBD.
