how to determine the molar extinction coefficient? εbc, where A is the absorbance, ε is the molar extinction coefficient, b is the path length of the cuvette and c is the concentration. Thus, the molar extinction coefficient can be obtained by calculating the slope of the absorbance vs. concentration plot.
Were there elk in Kentucky? South Fork Elk View: The largest elk herd in Kentucky resides in Breathitt County, and a viewing area has been established for visitors. From Jackson, which is located on KY 15 between Hazard and the Mountain Parkway, drive south on KY 15 for 3 miles, and then turn left on KY 1098.
How long have elk been in Kentucky? The Kentucky elk project is widely regarded as one of the most successful wildlife restoration efforts in the eastern United States and elk have now been thriving in the Commonwealth for over 20 years.
What year did scientists bring elk back to Kentucky? The process to reintroduce elk herds began in 1997. The elk were pulled from six Western states — Arizona, Kansas, North Dakota, New Mexico, Oregon and Utah — then released into the Bluegrass. By 2002, 1,541 elk were released into the Kentucky elk restoration zone.

what happens when bees go extinct?
Without bees, they would set fewer seeds and would have lower reproductive success. This too would alter ecosystems. Beyond plants, many animals, such as the beautiful bee-eater birds, would lose their prey in the event of a die-off, and this would also impact natural systems and food webs.
how the dodo bird go extinct?
Over-harvesting of the birds, combined with habitat loss and a losing competition with the newly introduced animals, was too much for the dodos to survive. The last dodo was killed in 1681, and the species was lost forever to extinction.
how did the permian mass extinction happen?
New research from the University of Washington and Stanford University combines models of ocean conditions and animal metabolism with published lab data and paleoceanographic records to show that the Permian mass extinction in the oceans was caused by global warming that left animals unable to breathe.
how to tame a wyvern ark extinction?
Unlike the other types of Wyverns, these can only be tamed by knocking them out, and taming them with Wyvern Milk. This can be done with Metal Tranq Arrows and a compound bow, a dino that deals torpor, or normal tranquilizers. Feel free to build a metal or stone trap to drag them into for KO.
what foods would we lose if bees went extinct?
We may lose all the plants that bees pollinate, all of the animals that eat those plants and so on up the food chain. Which means a world without bees could struggle to sustain the global human population of 7 billion. Our supermarkets would have half the amount of fruit and vegetables.
what was the mass extinction before dinosaurs?
The earliest known mass extinction, the Ordovician Extinction, took place at a time when most of the life on Earth lived in its seas. Its major casualties were marine invertebrates including brachiopods, trilobites, bivalves and corals; many species from each of these groups went extinct during this time.
what was the of life extinction of the dinosaurs?
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
how did anomalocaris become extinct?
The anomalocaris went extinct because of major climate decline. It was a swimming creature which possibly used flexible lobes on the sides of its body to propel itself through the water.
what causes animals to become extinct or endangered?
The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.
What percent of life was killed in the dinosaur extinction?
This event, known as the Cretaceous-Paleogene extinction event (K-Pg, for short), has been widely covered in popular articles, books, and TV shows, partly because the effects were so catastrophic. According to some estimates, 75 percent of life on the planet was wiped out.
What caused the mass extinction of the dinosaurs?
Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth’s climate that happened over millions of years.
How long does loot drop last in Ark?
5 minutes is the default for corpses and 5 minutes for normal items. You could try changing corpsedespawn lower, this should make only corpses despawn faster.
Why are slow lorises endangered?
As on July 2020, the Bengal slow loris is listed as Endangered on the IUCN Red List of threatened species, due to a combination of habitat loss and severe pressures from hunting. The pressures are causing a reduction in the population of more than 50 percent over three generations (approximately 24 years).
Was there a mass extinction before the dinosaurs?
Before the dinosaurs roamed the earth, a number of other species did — including other large sea reptiles and mollusks. But they abruptly died off about 200 million years ago, marking the end of the Triassic period, one of five major extinction events that scientists have identified throughout Earth’s history.
What happens to an animal or plant species when it becomes extinct?
What are the consequences of extinction? If a species has a unique function in its ecosystem, its loss can prompt cascading effects through the food chain (a “trophic cascade”), impacting other species and the ecosystem itself.
What sea turtle is extinct?
Listed as critically endangered, the Kemp’s ridley is the rarest species of sea turtle on earth. 6 Once abundant in the Atlantic Ocean, the species has declined in population by more than 80% over the past three generations.
Why is de-extinction a good thing?
Studies suggest that if large grazers were returned to the far north, biodiversity would increase again. It could be the same for other de-extinct animals, too. De-extinction provides a means to enhance biodiversity and help restore the health of ailing ecosystems.
What are differences between local extinction and functional extinction?
Introduction. Extinction is the complete disappearance of a species. Extirpation, also called local extinction, is the disappearance of a species only from a given area. Extirpation tends to make the extinction of a given species more likely by reducing that species’ population, genetic diversity, and geographic range.
Are all of the giant Galápagos tortoises are now extinct?
Two centuries ago, the Galapagos Islands were home to more than 200,000 giant tortoises; today four species are extinct and only 10% of the original number remain. The rescue and eventual recovery of the tortoise populations has been slow and steady.
Are lynx close to extinction?
The Iberian lynx has been brought to the brink of extinction because of a combination of threats that include the radical decrease of rabbits, the lynx’s principal prey; a serious reduction in habitat; being caught in snares set for rabbits; accidental deaths caused by speeding vehicles on the expanding road network, …
What foods will we not have if bees go extinct?
Bees perform a crucial role in fruit, vegetable, and nut production — without the pollination work they do, humans would have to say goodbye to (or pay very steep prices for) some of our most nutritious foods, including berries, apples, almonds, cucumbers, peppers, and seeds.
Is the golden tiger the rarest tiger?
The Golden Tabby Tiger is an extremely rare colour variation of this exquisite wild cat, and not a separate subspecies.
