#Bison Could Be reintroduced to Alaska North america's largest land animal will roam the Alaskan wilderness once again
Some Alaskans have rejected the idea of introducing an animal listed under the Endangered Species Act for fear that this might interfere with gas and oil development the Dispatch reported.
Habitats of endangered animals often cannot be used for certain commercial activities. Under the new plan the Alaskan bison would be designated as a nonessential experimental population that isn't necessary to the survival of the species
If their population reaches a certain size the animals would also be fair game for hunters according to the plan.
  A total of 132 animals already live in captivity at the Alaska Wildlife Conservation Center in Portage.
Establishing wild populations of this magnificent animal in Alaska would be a significant step toward its eventual recovery

Evidence suggests that by the early Cretaceous they were being replaced by large herds of herbivorous Ornithischians such as Stegosaurus Iguanodon and the Ceratopsians.
This hypothesis accounts for the extinction of the largest animals of the time the dinosaurs and giant marine reptiles.

#Ctenophores Semaphore Information About Earliest Animals This article was published originally at The Conversation. The publication contributed the article to Livescience's Expert Voices:
In a publication out today in Science a team of researchers in the computational genomics unit at the National institutes of health in Maryland report that Ctenophora are the most ancient multicellular animals.
Animals that appear superficially similar (such as jellyfish and comb jellies) can be quite different at a genetic level.
Together these animals comprise the non-bilateria which only makes sense when you realise that most of the animals we know are Bilaterians:
insects and fish and people and dogs all have bilateral symmetry. It now appears that the closest relative of Bilaterians are jellyfish
while the most ancient animals are the comb jellies. Ctenophores are delicate translucent creatures. They have eight rows of comb plates with cilia that provide them with locomotion.
They are carnivorous hermaphroditic marine creatures that do not sting. The sea walnut (M. leidyi) is native to the western Atlantic
This means that the ancestor of all animals may have had advanced quite an nervous system and these structures (but not their genes) were lost in the lineage that led to sponges.
Another major finding concerned the development of the main cell types in early animals. Embryonic cell layers develop into specific types of tissues.
Genes responsible for cell signalling were present even before the evolution of multicellular animals. This suggests single celled organisms were communicating with each other before they decided to organise themselves into bodies with different types of cells.
Second the three cell layers of well-known animals including ourselves is not unique nor is it a latecomer to animal evolution.
The earliest multicellular animals evolved their own form of mesoderm independently with unique genes allowing sophisticated biological organisation.
Third the ancestor of all animals had a nervous system which coordinated bodily functions. The nervous system was lost subsequently in the lineages that led to Porifera
Finally and most profoundly the shape of the evolutionary tree of all animals has taken on a new shape.
The earliest branch of the animal tree belongs to Ctenophora now confirmed to be the sister lineage to all other animals.
but so many animals dying off and doing so in what seems to be under 24 hours was puzzling to scientists.
Scavengers including bears and vultures ate most of the bodies with maggots and blowflies helping to reduce the elk herd to an eerie scattered sea of skeletons in the desert.
Under these conditions one species of alga Anabaena flos-aquae produces a neurotoxin anatoxin-A which depolarizes and blocks acetylcholine receptors causing death in animals that drink the pond water.
And the fast-acting toxin explains the animals'strange sudden deaths. In this case the algae appeared not in ponds
Though anatoxin-A can be deadly to other animals including dogs and cattle reports of human deaths are rare.
Once the trap catches a grizzly scientists use a sedative to immobilize the animal. Then they have only an hour to take blood
and fit a radio collar on the animal before it wakes up. A team led by the U s. Geological Survey (USGS) goes through this complicated procedure in the Yellowstone national park area about 70 to 100 times a year.
The safety of the animal is important as well as the safety of our research teams said Frank van Manen a researcher with the USGS who leads the interagency team.
You are working with a wild animal a very powerful wild animal. Obviously there's always a risk of something happening that we haven't seen before so vigilance is incredibly important here. 7 Iconic American Animals Researchers have conducted grizzly bear monitoring in various forms since 1973.
At that time Yellowstone was completing the closures of garbage dumps that had attracted bears. Because of these dumps the grizzlies started roaming for food in areas too close to the park's tourists leading to policies of euthanization and removal.
In response to lost pine trees the animals could switch to eating more meat or find other plants as a substitution van Manen said.
He had taken a population of wild animals and essentially domesticated them. And not just that he had figured out the mechanism by which it happened not by intentionally breeding for each physical trait
That is by allowing to breed those animals that were friendly toward people. There was one more change
Scientists who later studied the mouth-brooding animals found that there are actually two species naming one Rhinoderma darwinii (Darwin's frog) and the other Rhinoderma rufum (Chile Darwin's frog.

Treatment of Animals. This essay is adapted from one that appeared in Bekoff's column Animal Emotions in Psychology Today.
He contributed this article to Livescience's Expert Voices: Op-Ed & Insights. The question I ask in the title centers on the idea that supposedly smarter nonhuman animals (animals) suffer more than animals who are not as intelligent.
Indeed many people who write about other animals make this assumption as do those who develop
and enforce policies on which sorts of treatment are permissible and which that are not.
In the eyes of the United states Federal Animal Welfare Act animals such as mice and other rodents birds fish and invertebrates receive little
if any protection from extreme abuse and they're not even considered to be animals.
Indeed about 99 percent of the animals used in research are protected not by federal legislation
We are amending the Animal Welfare Act (AWA) regulations to reflect an amendment to the Act's definition of the term animal.
The Farm Security and Rural Investment Act of 2002 amended the definition of animal to specifically exclude birds rats of the Genus rattus
Common sense tells us that the animals who are excluded from that definition of animal are indeed animals.
In 1994 I published an essay titled Cognitive ethology and the treatment of nonhuman animals:
and suffering are still being considered even in light of a plethora of new data on the cognitive and emotional lives of other animals.
and sentience based on more recent research on animals'fascinating minds and their capacity to suffer
Human-centric claims about the ways in which animals interact in their social and nonsocial worlds are often the basis for decisions about how animals can
or should be used by humans in various sorts of activities. Thus the treatment of animals is linked often tightly to how people perceive them with respect to their ability to perform behavior patterns that suggest that they can think
if they have beliefs desires or make plans and have expectations about the future. Much comparative research still needs to be done before any stipulations can be made about how an individual's cognitive abilities can be used to influence decisions about how she
and nervous systems are different from those of animals with whom humans identify most readily or with whom people are the most familiar.
When people are uncertain even only slightly about an animal's ability to experience pain
or to suffer that animal should be given the benefit of the doubt. Are dogs more intelligent than mice
and data concerning the cognitive emotionaland moral lives of animals. Scientists have uncovered numerous surprises about species that were assumed to be not all that smart or sentient.
not only the nature of the cognitive emotional and moral lives of animals but also how much they suffer
Likewise asking if dogs suffer more than mice ignores who those animals are and what they have to do to survive
and thrive in their own worlds not in ours or those of other animals. Furthermore with respect to the original abstract and what I wrote in the essay itself a great deal of subsequent comparative research has shown that
what animals know and feel based on solid evolutionary theory (e g. Charles darwin's ideas about evolutionary continuity) has been borne out by numerous studies
It's bad biology to rob animals of the traits they clearly possess. For example we share with other mammals
Humans need to abandon the anthropocentric view that only big-brained animals such as ourselves nonhuman great apes elephants
In addition numerous stories about the lives of animals have opened up areas of detailed research. Indeed as my colleague Dale Jamieson and I like to say the plural of anecdote is data
which they concluded Convergent evidence indicates that nonhuman animals have the neuroanatomical neurochemical and neurophysiological substrates of conscious states along with the capacity to exhibit intentional behaviors.
Nonhuman animals including all mammals and birds and many other creatures including octopuses also possess these neurological substrates.
and suffering of less intelligent animals very seriously and that speciesist arguments about higher and lower animals need to be shelved.
There are no'unintelligent'animals; only careless observations and poorly designed experiments. What would be the implications of discovering that some animals are not all that cognitivethat they have impoverished relatively cognitive abilities
and lives or that they have fewer memories and fewer beliefs about the future? First we would have to show that these so-called cognitive'deficiencies'are morally relevant.
and animals a point raised by Guelph University's Ian Duncan. Second one could argue that
Not allowing certain expectations to be realized is a serious intrusion on those individuals'lives perhaps more serious than not allowing some expectations in animals with richer cognitive lives to be realized.
if the memories of some animals are developed not well (they live in the present and lack the ability to know the passage of time) then their pains have no foreseeable end.
Related to that line of reasoning is the observation by Alastair Hannay that many animals even those for
Those animals seem to try to remove themselves from situations that they find aversive ituations they seem not to prefer that resemble situations that normal human beings
and other animals do not prefer either. Even if those individuals do not imagine that there is something that is more pleasurable
which we are associated unfamiliar that is with a preference shown by an animal who we think is'not all that cognitive
It is possible that some animals experience pain and suffer in ways that we cannot yet imagine
despite inherent shortcomings it is possible that preference tests that are developed for a broad spectrum of animals would help to shed some light on the phylogenetic distribution of sentience.
because when animals do not do what we expect them to do or when they do nothing it is possible that they are motivated not by the situation that we create.
As University of Pennsylvania researchers Paul Rozin Dorthy Cheney and Robert Seyfarth suggest there are as yet unknown factors that influence an animal's behavior.
