...Population Ecology of Some Warblers of Northeastern Coniferous Forests (ROBERT H MACARTHUR) 1. What journal was the article published in? This article was published October 1958 in The Ecological Society of America 2. Find five terms that you do not know the meaning of in the paper. DEFINE these terms Non parametric statistics: is defined to be a function on a sample that has no dependency on a parameter, and whose interpretation does not depend on the population fitting any parametrized distributions. Statistics based on the ranks of observations are one example of such statistics and these play a central role in many non-parametric approaches. Stippled Area: is the creation of a pattern simulating varying degrees of solidity or shading by using small dots. Such a pattern may occur in nature and these effects are frequently emulated by artists. The term stipple can also apply to a random pattern of small depressions applied to a surface to increase the friction and make the surface easier to grip. Hawking: is a feeding strategy in birds which involves catching flying insects in the air. The term usually refers to a technique of sallying out from a perch to snatch an insect and then returning to the same or a different perch. This technique is called “fly catching” and some birds known for it are several families of “flycatchers”, for example Old World flycatchers, Monarch flycatchers, and Tyrant flycatchers. Allopatric: Occurring in separate, non-overlapping geographic...

...The taiga biome goes by many different names, including the boreal forest and coniferous forest. The taiga has short summers, with an average of fifty seven degrees Fahrenheit and fourteen degrees Celsius. Winters are cold and snowy in the forests, with the average temperature at about fourteen degrees Fahrenheit or negative ten degrees Celsius. These coniferous forests are most often and abundantly found near the top of the world, just under the main tundra biome. Taigas span across Eurasia and North America. The taiga is one of the largest biomes, covering about twelve million square kilometers or more than four and a half million square miles. The Russian taiga alone covers an area larger than the contiguous United States. Boreal forests are under attack from industrialization....

...Spokane is much colder and drier with its Mediterranean climate than Austin is with its humid subtropical climate. These result in different fauna and flora in each of their terrains. Spokane experiences coniferous plants that grow well in the cold and elevated area. Austin experiences more deciduous plants, but only those that will survive the very hot summers. The difference between the animals found in both is rather big. Austin, unlike Spokane, has reptiles because of the warmth. The size of the animals in Spokane’s environment tends to be larger and built to survive the cold weather. Although different, the two places do share the common predatory mammal, the...

...many nonnative plants that have become a part of the scenery in California. The best way to understand the state’s vegetation is to first understand the floristic provinces. In North America there are 12 floristic provinces with four of those found in California (Map #1). California itself has five major biomes, some of which can be found at RSABG. Four of them are in the California floristic province and the fifth is in both the Great Basin and the Sonoran floristic province. Each of which contains many different types of communities in them. The California floristic province has the coniferous forest biome, the oak woodland biome, the grassland and marshland biome, and the chaparral and coastal sage scrub biome. The Great Basin and Sonoran floristic province has the desert scrublands and woodlands biome. All of the five biomes (Map #2) in California have different climates. The Coniferous forest is highland with a cool or warm Mediterranean, while the Oak woodlands is semi-arid, but also has a cool or warm Mediterranean. The Chaparral and coastal sage biome is very similar to the Grasslands and marshland biome in that they both semi-arid, but the chaparral also has a warm Mediterranean. The Desert scrublands and woodlands depending on which province it is found in are either semi-arid or arid. The fan palm oasis (Picture #2) is found within the desert woodlands portion of the desert...

...The Arctic and subarctic regions Compared with other biomes, the tundra biome is relatively young, having its origin in the Pleistocene (1,600,000 to 10,000 years ago). Individual plant and animal species of the tundra, however, probably first appeared in the Late Miocene (11.2 to 5.3 million years ago) or Early Pliocene (5.3 to 3.4 million years ago). Coniferous forests were present on Ellesmere Island and in northern Greenland, the northernmost land areas, in the mid-Pliocene (2.5 million years ago). Most paleoecologists believe that tundra flora evolved from plants of the coniferous forests and alpine areas as continents drifted into higher and cooler latitudes during the Miocene (23.7 to 5.3 million years ago). The Antarctic region Antarctica has been isolated from other continental landmasses by broad expanses of ocean since early in the Tertiary Period, about 60 to 40 million years ago. Prior to its separation it existed, along with Australia, South America, peninsular India, and Africa, as part of the landmass known as Gondwanaland. This long separation has impeded the establishment and development of land-based flora and fauna in the Antarctic. Other significant factors that have hampered terrestrial biotic evolution are the harsh climate, the ice cover that completely engulfed the continent during the Pleistocene glaciations, and the present limited number of ice-free land areas, which are restricted primarily to the coastal fringes and nunataks (mountain peaks surrounded...

...UNIT 1 EDEXCEL GEOGRAPHY MAY 2010 QUESTION 8 a) Suggest why some groups and communities view the melting of Greenland’s ice sheet as an opportunity rather than a threat. (10) Some groups and communities view the melting of Greenland’s ice sheet as an opportunity rather than a threat because the melting ice creates some commercial advantages for the Arctic region; the Northern Sea Route, North of Canada, is the quickest way of travelling from Europe to the Pacific and Asia. This also increases the tourism opportunities because 30% of Inuit earn income from sculpture and printmaking for tourists, as the tourist ships are able to transport to the northern Canada. As the rapidly melting ice offers commercial opportunities in shipping, tourism and oil and gas extraction, the world’s largest economies are struggling but as well as trying to achieve and get hold of the region within the Arctic. A region in the Arctic thought to be contain 30% of the world’s undiscovered gas and 13%% of undiscovered oil. In addition, more oil can be used by groups of Inuit for essentials like the uses of fossil fuels. In Alaska, due to the new drilling activity, it creates new job opportunities and incomes for the local economy, which means more Inuit, get the job opportunities like this. Furthermore, there are currently four more mining operation being setting up and soon, it will provide jobs for natives in Greenland. In 2007, the Northwest Passage between Canada and Arctic melted enough to...

...can be defined as the variation of life within a biome or ecosystem. Unfortunately, Biodiversity around the world is at risk due to human interference and climate change. However changes within these forest and/or ocean ecosystems also impact the human population, as we depend on these crucial bionetworks for our very own existence. • The Boreal forest is a band of forest that stretches across the northern hemisphere, which includes the following countries: Canada, Russia, United States and the northern countries of Europe such as Sweden, Norway etc… (Green displays the areas where the Boreal forest is situated) • Within Canada, the Boreal forest region covers more than 290 million hectares. •This forest is primarily dominated by coniferous trees, namely: Jack Pine, Balsam Fir, Red Pine, White Pine, Black Spruce, White Spruce, Tamarack, Paper Birch, Eastern White Cedar, etc… • The leading cause of most threats upon ecosystem biodiversity is climate change; such is the case in Canada’s the Boreal forest. • Climate change also has an effect on the number of forest fires. • Invasive alien species are also a huge factor in destroying biodiversity in the Canadian Boreal forest. • The Boreal forest is the largest intact forest and wetland ecosystem remaining on earth. • One of, and perhaps the biggest threat to biodiversity in the Boreal Forest is Human infringement. • In summation the best way to preserve the Canadian Boreal forest would be to make people aware.

...The Tawny Owls are found throughout Europe and North Africa. They are also found eastwards to Iran and Western Siberia. The Tawny Owl can range in colors from darkish brown, light brown, gray and darkish red. They have big black eyes. The Tawny Owl also has a small pointy nose and small curved claws. The claws are blackish with dirty white bases. The owl’s habitat usually varies. They like to live in mostly wooded and forest-like areas like cemeteries and parks. The Tawny Owls almost always breed in woodlands and forests. They like to inhabit coniferous forest. The Tawny Owls are always hunting at night. They are usually quiet listening, waiting and watching for their prey. When the owls spot the animal, it swoops down, covers the prey and instantly kills it. The animals they eat are rabbits, mice, voles, earthworms, insects, beetles, birds, frogs, fish, lizards and molluses. Since the Tawny Owl is relatively a small bird, it has a number of predators. Those predators are usually dogs, cats, and foxes. But it also includes hawks, eagles, and other large birds. As far as the Tawny Owl eggs, the main predators are squirrels and rats. In conclusion, the Tawny Owl can be known as a small owl. It hunts at night. They have predators but also a long list of prey. They are very meticulous while hunting. In fact they rely on their sight and hearing to kill their prey. Bibliography Lewis, Deane. The Owl Pages. 22 July 2013. <http://www.owlpages.com/>. Nottinghamshire...

...moose, bear, squirrels, fox and bats. The tropical rainforest biome is an ecosystem that covers 7% of the earth’s surface. They are found all over the world but the majority of the tropical rainforest lies in south america in brazil.The average temperature of the tropical rainforest remains between 70 and 85 degrees F. The tropical rainforest is very rainy. Most of the animals living in the tropical rainforest live in the trees. There they can find all of their necessities and rarely have to come down to the floor. Because of the amount of trees in the tropical rainforest biome, it is responsible for the majority of oxygen production in the air that we breathe. Coniferous forest is a kind of biome situated in temperature regions of the globe that experience warm summers and cool winters. Coniferous forests thrive in tropical Pg.6 Aquatic Ecosystems There are four major oceanic zones where plants and animals live in the ocean. The four major zones are intertidal zone, neritic zone, open ocean zone and benthic zone. These zones contain the largest ecosystem on earth. The intertidal zone is the area of the seafloor between high tide and low tide. It bridges the gap between land and water. Tide pools, estuaries, mangrove...

...Hiking has always been a passion of mine, I find it to be peaceful and exhilarating at the same time. One of my lifetime goals is to complete the three month trek (2,659 miles) down the Pacific Crest Trail, it expands from Canada to Mexico, going through Washington, Oregon and California. But that's for the future. In the meantime, averaging about twice a year, I get away to the Redwood National Forest located in Northern California. Just as the sun is rising is the prime time to walk amongst the giant coastal redwoods, the air crisp, cleansed by the morning dew that is still clinging to the foliage and spider webs. Branches reaching out, entangled with its neighbors, allowing the sun's rays to project light beams through the coniferous forest....

...A biome is a group of ecosystems that share similar climates and organisms. In Miller and Levine Biology, 10 biomes are discussed. They are the Tropical Rain Forest, Tropical Dry Forest, Tropical Grassland, the Desert, Temperate Grassland, Temperate Woodland, Temperate Forest, Northwestern Coniferous Forest, Boreal Forest, and the Tundra. They all have a vast amount of differences between all of the biomes, and they will be discussed. Although not discussed in the book, the taiga is the biggest biome. The average temperature of the taiga is 32 degrees fahrenheit with about 12 to 33 inches of precipitation per year. There is little diversity in plant life. A few broad leaf tree species live in the taiga but mostly evergreen trees are the only ones that have adapted to really thrive in this environment. There are some animals that have adapted to live in the cold and snowy environment. A predator called the ermine has a thick coat of dark fur that turns white in the winter. The snowshoe rabbit also has a fur that turns white in the winter. The wolverine is able to mate during ideal conditions by delayed implantation in which they suspend dormant fertilized eggs until the conditions are ideal for bearing their young. Rainforests are the most diverse having more than 15 million species living in the biome. The rainforest biome is sometimes separated into two different biomes. They are referred to as tropical and temperate. The tropical rainforests are located between the Tropic...

...The Bengal Tiger The Bengal tiger is a carnivorous, mammal primarily from India. It lives in habitats such as the coniferous Himalayan Forest, the mangroves of the Sunderbans, the hills of the Indian Peninsula, or the forests of Rajasthan and Northern India. At one time Bengal tigers were scattered throughout Asia. Now they are generally found in India and some regions of Bangledesh, Bhutan, Nepal, and Myanmar. There is approximately 4,000 alive in the wild now, and about 300 are in captivity in zoos around the world. Bengal tiger's are one of the largest and most feared cats in the cat family. An adult tiger can weigh any where from 350 to 550 pounds. The adult males weigh an average of 480 pounds, while the females weigh about 300. Their body lengths are between 6 and 9 feet long! A Bengal tiger hunts primarily deer, wild pigs, water buffalo, birds and other small mammals. When driven from hunger a this tiger will eat almost anything. Crocodiles, lizards, fish, and even humans are eaten by a frustrated Bengal tiger. They eat meat and only meat. Their style of attack is differant from the cheetah's and the lion's; who hunt in open habitats. Although it is a heavier predator than that of the lion and cheetah, it averages about 50 deer a year. Bengal tigers need a wide forest-like areas to hunt their prey. They are known to hunt alone, but have been found to hunt in packs. These tigers are semi-nocturnal, because they sometimes hunt at night. They use flying tactics...
