climate-buffering effects for pikas. Elevation was included as a covariate because it often varies with suite of environmental variables (Millar & Westfall 2010). Models represented the following hypotheses: pika persistence is related to the severity of changes in temperature and precipitation since initial pika detection. The pika are

The pika is a small-sized mammal that is found across the Northern Hemisphere. Despite their rodent-like appearance, pikas are actually closely related to rabbits and hares. Pikas are most commonly identified by their small, rounded body and lack of tail. Pikas prefer the colder climates and are generally found in mountainous regions and rocky areas where there tend to be fewer predators. There are more than 30 different species of pika that range in colour and size, across Asia, North America and

“Discuss the origin and significance of diversity within and between species using examples from a named Eukaryote taxonomic group of your choice.” Introduction Diversity within and between species depends on various evolutionary processes and can be traced to some sort of genetically altering event, whether it be a mutation, physical isolation, inbreeding depression etc. This essay seeks to analyze the origins and significance of diversity within the taxonomic group of lagomorpha, analyzing the

A pika is a small mammal in the ochotonidae family. Pikas have a round body, very short limbs, rounded ears and are usually short haired. (and really cute) They look more like a mouse but are way more closely related to a rabbit. There are about thirty different types of pikas that are still alive. Almost all pika species are extinct, and all of the species that are alive, are highly endangered. According to Natureworks, there are two different pika species in north America, and twenty-eight in Asia

Once upon a time, there was a young boy who usually couldn’t push keys or buttons trapped in the ordinary world. Carroll Pika was a chubby boy who was afraid of one thing: buttons. No, not the buttons on shirts, but keys on a computer and buttons on elevators. His fear started when he was in first grade. Carroll came from a family of 16. His dad was an accountant and his mom was a chiropractor. He was the youngest and he always got the worst chores like cleaning the toilet. But that wasn’t the worst

Afghan Pika from Northern Khorasan Province, North-eastern Iran, focusing on differentiation and genetic diversity. The result of cytochrome b region of mitochondrial gene variation indicated high levels of haplotype diversity (0.834±0.059) among all individuals of O.rufescens and low nucleotide diversity (0.0024±0.0008). In comparison with other Pikas, afghan pika showed low haplotype diversity but nucleotide diversity was high in Afghan Pika than other species of Pikas except collard pika (Table

From criminal coconut crabs to cannibalistic lizards, and everything in between, Episode 1 of the 2018 PBS Series Natural Born Rebels takes you on a roller-coaster journey across the globe to meet animals that will lie, cheat, steal, and even use brute force to get a quick meal. It’s a fact of life: every living thing must eat to survive. So, what happens when the number of animals in an area surpasses the available food supply? More often than not, the predator population balances out the population

In this essay I express how the melting of the polar ice caps in the North Pole is affecting the survival of habitats of organisms around the world. The common misconception is that only polar bears are suffering from global warming. Because of rapid climate change in multiple areas around the globe, many organisms are unable to live in their normal habitat. They are unable to adapt to these new conditions as fast as they are changing. There are many effects of global warming that is affecting the

Introduction One of the most important environmental influences on ecosystems is climate. Greenhouse gas pollution is acquiring heat in the atmosphere and inordinately raising global temperatures. Colorado, for example, has warming predictions of 2.5 degrees Fahrenheit by 2025 and up to 4 degrees by 2050. The impact of climate change can and will affect ecosystems in numerous forms. Such an impact is that warming of the climate will compel a variety of species to shift to higher elevations
