Question: In short paragraph explain the ecological roles of bowhead whales.

 

 

 

Notes:  Ecological roles: document information about the specific roles that the organisms you are profiling play in the ecosystem. Describe the kind of interactions (intra/interspecific) they are involved in. Address also the factors that affect (positively/negatively) the fitness of the species in your examples, or In the ecological roles, focus specifically on the species. and mention their food, or ways to get food, species they feed on, species that predate upon them, if plants, what are the species that pollinate them, how their seeds are disperse.....if you mention trophic mismatch, then provide the details for that, for example... which species are affected, etc? 

Whales are at the top of the food chain and play an important role in the overall health of the marine environment. The conservation status of the baleen whale as a whole is listed as "least concern", but some populations (such as near Greenland) are threatened with extinction. Whales, on average, sequester the equivalent of 1,000 trees in their lifetime. By 2050, there could be more plastic than fish in the ocean. More than 240 wildlife species worldwide, including whales, are known to ingest plastic.

Marine plastic pollution harms marine life in two ways: ingestion and entanglement. A recent study found that flexible plastics account for the largest proportion of garbage-related deaths.

Step-by-step explanation

Bowhead whales are one of the few whale species that reside almost exclusively in Arctic and subarctic waters. Of all large whales, the bowhead is the most adapted to life in icy water. Adaptations to this environment include an insulating layer of blubber that can be up to 1.6 feet thick. Commercial whaling for bowheads off Alaska began in the early 1800s and lasted until the early 1900s.

Whales are at the top of the food chain and play an important role in the overall health of the marine environment. The conservation status of the baleen whale as a whole is listed as "least concern", but some populations (such as near Greenland) are threatened with extinction. Until the last century, they were traditionally hunted by commercial whalers for oil, meat and whale bones. Today, communities in the United States and Russia hunt whales for food. This whaling industry is approved by the International Whaling Commission (IWC) and is sustainable.

This predominantly arctic species is associated with ice fields. Therefore, the nature of the movement is affected as the ice melts and freezes.
Bowhead whales can penetrate at least 7 inches of sea ice thanks to their large skull and powerful body.

Bowhead whales (Balaena mysticetus) typically spend the entire year in Arctic waters. The species has been a victim of commercial fishing and it will take many decades for their populations to recover.
Adult Greenlanders are completely black except for the anterior part of the mandible is white and noticeably raised. They can grow up to 60 feet tall, but still jump completely out of the water. Greenland predators filter food through their whiskers by opening their mouths and filtering plankton from the surface, water column, or seabed.
Data from indicate that the butterfly-headed whale may be one of the longest-living animals on the planet. Based on the discovery of stony harpoon spots in their fat and analysis of eye tissue, scientists believe that bald whales can live more than 200 years.

Until the last century, Greenlandic whaling ships struggled to hunt for oil, meat and whiskers. Some populations are getting better thanks to the suspension of the International Whaling Commission on Commercial Whaling (IWC). Like other large whales, bowhead whales are threatened by habitat loss, toxic substances and climate change, offshore oil and gas exploration, and increased transport in the Arctic Ocean.

Today is the day to honor one of the most iconic species on Earth, the whale. Conserving whales is critical to protecting the healthy oceans of all of us. They fertilize marine ecosystems and even help overcome the climate crisis. Whales, on average, sequester the equivalent of 1,000 trees in their lifetime.

The health of whales is directly related to the health of the sea and is an important indicator of the health of the sea. They even help grow  more than $2 billion whale watching tourism industry worldwide. But even these sea giants are being affected by plastic pollution, which is "the deadliest predator in the ocean."Plastic waste pollutes every corner of our oceans, threatens marine life, and includes the seafood we eat. From local beaches to remote tropical islands and poles, plastic is messing up the oceans and killing wildlife. This is the clearest example of human impact on our oceans. Currently, more than 11 million tonnes of plastic enter the ocean every year. By 2050, there could be more plastic than fish in the ocean.

Marine plastic pollution harms marine life in two ways: 

Ingestion and entanglement. More than 240 wildlife species worldwide, including whales, are known to ingest plastic, which can cause internal injuries and death. A recent study of marine life found that flexible plastics, such as plastic bags and packaging, account for the largest proportion of garbage-related deaths, primarily due to gastric obstruction. Whales aren't the only species affected by plastic debris. Hundreds of scientific papers suggest that dolphins, sea turtles, seabirds and fish around the world are also inescapable.

For many years I have studied sperm whales. Often referred to as "elephant seals," sperm whales, like land-dwelling whales, live in highly social and complex matrilineal societies. They eat squid and spend 70% of their life searching for food in deep water. Plastic debris is particularly difficult for this species. One whale on the beach swallowed 135 items, the highest number ever recorded for this species. It was mainly a plastic bag that could look like a squid of kit. Dead whales and dolphins in trash have seen swimming in a few days. This can increase the risk of delivery or boat. For this reason, researchers believe that the deaths caused by the current plastic may be more common than they have been reported.
One of the most destructive types of sea plastic contamination is generally abandoned and lost, or aqueous fishing is generally called "ghost gears". Approximately 10% of the world plastic contamination of the sea consists of a rope for fishing networks and fishing. Every year 300,000 whales, dolphins and pigs mistakenly kill the net and lines, and slowly and painful death through flask, hunger or depletion.
Plastics take hundreds or thousands of years to decompose, during which time they can damage the environment. Ghost equipment can continue to trap all marine species in its path for years to come, potentially destroying important food resources and endangered species such as whales, dolphins, seabirds and turtles. Marine plastic pollution damages important marine habitats and poses a threat to ships and livelihoods.

Ven Microplastics is a small plastic particle with a small size of less than 5 mm, and the most rich garbage tank in the ocean environment was found in whale and mine. But their impacts are very different. This miniaturization can be destroyed from sunlight and other environmental factors of invisible toxic compounds. These compounds have the risk of marine ecosystems and biodiversity, and for many years, you can interfere with the development and health of marine animals through the beach food networks and are species (called biomotions and biological axes).
Plastic pollution is a global problem that requires global plastic contamination for global plastic contamination, and is made at 1 inch and we are trying to resolve it with a coordinated global effort. This operation can solve a pair of methods:
The United Nations' Global and Legal Obligation Agreement is set to a priority to stop plastic leaks by 2030. Each country in a country is part of this plastic crisis and each must be part of the solution. We need a global response combined through clear promise and responsibility that can prevent and control plastic contamination. We need immediate UN contracts, which will not be waste or contaminated because it stops the plastic leakage and accelerates the transition to the circular economy of the plastic.The government implements the best fishing mechanism management practices to sign GEAST GEAST (GGGI) Global Initiatives and to prevent gear loss. GGGI is the world's only global cross-sector coalition of 100 organizations, including the WWF. By joining the GGGI, countries gain access to critical technical assistance to help solve the phantom gear problem in their fisheries, contribute to the collective impact of GGGI and its members, and develop global capabilities to address this problem globally You can.
For me, whales are an inspiring symbol of the sea. The good news is that over 750,000 people have signed the WWF Petition to Combat Plastic Pollution. This is a good start. Support for the United Nations treaty is growing rapidly. A growing number of countries have expressed support for it, with 50 companies supporting the call for a new treaty. This coordinated global response is needed to help governments and businesses level the playing field and make a difference to solve this problem in a generation.
Commercial whaling severely reduced bowhead whale numbers from historical levels. Western Arctic bowheads have shown considerable recovery since the end of commercial whaling. The Okhotsk Sea population, more heavily exploited in the past, remains at a dangerously low population of only a few hundred individuals. Genetic research has shown that these two North Pacific populations are distinct.
