For the first seven months of their training period, the dolphins were acquainted with several gestures and sounds. They were presented with simple two-choice sound-discrimination stimuli to familiarize them with some sounds that the study would use. Correct responses were rewarded with freshly thawed silver smelt fish. The positive reinforcement aimed at developing a positive attitude toward learning and encouraging dolphins to solve problems. Gestural training was also initiated in this period to accustom the dolphins to responses that that would later be expected from them in the study. Akeakamai was made to specialize in gestural
The rapidly increasing world population (1 billion in 1820, 2 billion in 1920 and probably 7 billion in 2020) is putting enormous pressure on the habitats of many animals, as people use more space for housing and for the production of food. The Maui Dolphin is one species affected by food production as carried out by the fishing industry. I decided to do research on the Maui dolphin because of its uniqueness and rarity. My purpose is to find out more about the endangered status of the Maui Dolphin, why it has become rare, what problems are involved and what can be done to improve the situation.
Furthermore, the marine mammal science community, which has long maintained a neutral stance on the question of whether orcas are a suitable species for captive display, has finally recognized the need to engage. An informal panel discussion on captive orcas is scheduled at the 20th Biennial Conference on the Biology of Marine Mammals in December, the first time this topic will be openly addressed by the world's largest marine mammal science
Recent evidence suggests that whales may not have always inhabited the oceans. Bones of an ancient ancestor of modern day whales, the Basilosaurus, were discovered in Pakistan that suggest whales evolved from a wolf-like creature. This genus of an early whale lived 34-40 million years ago in the late Eocene. These fossils show many different features in common with both modern day whales and modern day land mammals. Since the discovery of these bones, many other evidences show that whales are a likely descendant of the Basilosaurus through many different ways, such as embryologic comparison and DNA testing. Whales aren’t the only suspected descendants
In marine mammal biology a large portion of the study is dedicated towards the study of adaptations to the marine environment. By comparing the anatomy between marine mammals and terrestrial mammals scientists can better understand evolutionary history of how these two categories of mammals diverged from one another. The purpose of this lab was to study the anatomy of different marine and terrestrial mammals and compare their similarities and differences in homologous traits and how adaptations were made specifically for marine mammals to survive the aquatic environment. To accomplish this bones of different species of animals were studied since these structures serve as the basis for comparison across species as well as an indicator of each animal’s individual morphology and physiology. A standard measurement protocol for bones of particular regions of the skeleton was established with emphasis on length versus width ratio as well as it’s overall size relative to its more complex features, i.e. humerus length versus hand length.
PROMISE surveys the family members of deceased veterans through The Family Assessment of Treatment at the End of Life (FATE) questionnaire (DVA, 2012). Along with survey feedback and medical records, the Veteran’s quality of end-of-life services are measured and disseminated. The report findings are issued quarterly to health facilities as well as the Veterans Integrated Service Network (VISN) leadership, and the VA Central Office (DVA, 2012).
Trego works at the Conservation Ecology Lab at San Diego State University in California. She reported her team’s early findings on December 14, at the Society for Marine Mammalogy meeting in San Francisco.
The population decline in monk seals is due to several different factors with the biggest reason due to the low pup and juvenile survival rates (Curtice et al, 2011). At the Kure Atoll on the Northwestern Hawaiian Islands, 32 pups were observed in 1964 and 30 pups were observed in 1965. Of these pups born, all but one died or disappeared within 60 days after birth. This was also seen in the 1970’s at Green Island and Kure Atoll, where a mean population of 17 and 14 seals, respectively, was counted on these beaches, with a birth total of 10 showing a population decline of 70% (Gilmartin et al, 2011). The juvenile survival rate is still seen today with one in five monk seals surviving to the reproductive age, with one year old seals having the highest mortality rates (Norris et al, 2011).
Since my last response paper, my response paper has become more nuanced. Specifically, I have developed my stance as to be in favor of encryption, human rights, and a utilitarian framework. After looking to the literature, I have developed my opinions more thoroughly and tend to lean towards preventing the social and economic ramifications of limited encryption.
Manatees (order Sirenia, genus Trichechus) are the source folklore and possess many unique characteristics. With three recognized species, manatees (along with their relative, the dugong) also possess a unique range, limited mostly to coastal bays and waterways of the warm southern coasts. They are also the world’s only herbivorous marine mammals, and they have a highly-developed mouth with bristles. Although much-loved, the manatee population is currently under threat
There are so many interesting things about them. Dolphins have been around for about 15 million years now. They’re extremely intelligent, probably even more intelligent than us humans. Dolphins are becoming endangered because of humans and many don't know that. They are known as the oceans most kind animals.Dolphins have originated millions of years ago,are extremely endangered,and are becoming endangered.The most important thing to know about dolphins would probably be how they originated because without that those cute aquatic mammals wouldn't even exist.
and used to address each other, in a similar way to how humans use names.
Transition: After learning about a dolphin’s sense of communication, we can now build upon this information by examining their unique behavior.
One of the objectives of this study is to identify the student’s response after using the think aloud strategy. The overall number of students that have been chosen as the respondents were 26 students, 14 = male and 12 = female. The results of the data analysis had shown that 26 participants have a positive response towards think-aloud strategy after it has taught to them. It is believed that students’ responses were influenced by the researcher instructions and the implementation of the think-aloud strategy in the reading activities .Findings from the study in regard to reading strategy assert the role of the researcher is significant and effective. These show how students’ performance was not negatively affected but positively since researcher
There is something about dolphins that fascinates me. They are some of the most intelligent and beautiful animals that I have ever seen. Their faces are so cute that every time I look at a dolphin it looks like it is smiling at me and wants to tell me something. The noises they make represent some kind of language and it makes me wonder if they can really communicate. I also want to know what kind of feeling they have and whether they have emotions. This is why I chose to do this I-search project on dolphins; the different kinds of dolphins there are, the places that they can be found and their mental abilities.
Maui dolphins are very critically endangered. This is commonly said to be caused by the human influence of set nets. Fishermen are using set nets in the water where the fish are driven into. Unfortunately, these are very dangerous to the Maui Dolphins as due to the biological concept they hold of echolocation which is the way they determine where objects are by the reflection of sound, they are unable to detect the very fine nylon strings. (4) (1) This leads to the dolphins swimming into the set nets. Also, due to the biological concept of Maui Dolphins lacking the ability to swim backwards, they are not able to free themselves from the net and often drown after a couple of minutes as they “cannot reach the surface to breathe” (4) due to them being air breathers.
