Ross's Goose
Ross's goose (''Anser rossii''), formerly ''Chen rossii'', is a white goose with black wingtips and a relatively short neck. It is the smallest of the three Anser (genus), white geese that breed in North America. It is similar in appearance to a white-phase snow goose, but about 40% smaller. Other differences from the snow goose are that the bill is smaller in proportion to its body and lacks "black lips". Like snow geese, Ross's geese may exhibit a darker "blue" phase or morph, though this is extremely rare (<0.01% of adult birds). Before the early 1900s, this goose was considered a rare species, possibly as a consequence of open hunting, but numbers have increased dramatically as a result of conservation measures. It is now listed as a Least-concern species, species of Least Concern by the International Union for Conservation of Nature, IUCN, and is protected by the Migratory Bird Treaty Act of 1918, Migratory Bird Treaty Act. Ross's g ...

John Cassin
John Cassin (September 6, 1813 – January 10, 1869) was an American ornithology, ornithologist from Pennsylvania. He worked as curator and vice president at the Philadelphia Academy of Natural Sciences and focused on the systemic classification of the academy's extensive collection of birds. He was one of the founders of the Delaware County Institute of Science and published several books describing 194 new species of birds. Five species of North American birds, a cicada, and a mineral are named in his honor. Early life and education Cassin was born in Upper Providence Township, Delaware County, Pennsylvania, Upper Providence Township, Pennsylvania on September 6, 1813. He was educated at the Westtown School in Westtown Township, Pennsylvania. His great Uncle, John Cassin (naval officer), John Cassin, was a commodore in the U.S. Navy and served in the War of 1812. He served in the Union Army during the American Civil War and was held prisoner in the infamous Confederate Libb ...

Wet Meadow
A wet meadow is a type of wetland with soils that are Solubility, saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Hydrology and ecology Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes. Unlike a marsh or swamp, a wet meadow does not have standing water present except for brief to moderate periods during the growing season. Instead, the ground in a wet meadow fluctuates between brief periods of Flood, inundation and longer periods of Hydric soil, saturation. Wet meadows often have large numbers of wetland plant species, which frequently survive as buried seeds during dry periods, and then regenerate after flooding. Wet meadows therefore do ...

Birds Of The Arctic
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ...

Geese
A goose (: geese) is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera '' Anser'' (grey geese and white geese) and ''Branta'' (black geese). Some members of the Tadorninae subfamily (e.g., Egyptian goose, Orinoco goose) are commonly called geese, but are not considered "true geese" taxonomically. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller. The term "goose" may refer to such bird of either sex, but when paired with "gander", "goose" refers specifically to a female one ("gander" referring to a male). Young birds before fledging are called goslings. The collective noun for a group of geese on the ground is a gaggle; when in flight, they are called a skein, a team, or a wedge; when flying close together, they are called a plump. Etymology The word "goose" is a direct descendant of Proto-Indo-European ''*ǵʰh₂éns''. In Germanic langu ...

Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change between grazing events. Successful planned grazing strategies have been in support of the American bison of the Great Plains, or migratory wildebeest of the African savannas, or by holistic planned grazing.

Rhododendron Lapponicum
''Rhododendron lapponicum'', the Lapland rosebay, is a dwarf rhododendron species found in subarctic regions of North America, Europe and Asia, where it grows at altitudes ranging from sea level to . It is an evergreen prostrate shrub growing to in height, with leaves that are oblong-elliptic or ovate-elliptic to oblong-obovate The following terms are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (that is, the leaf blade or 'lamina' is undivided) or compound (that is, the leaf blade is divided into two or more leaflets) ..., 0.4–1.5 by 0.2–0.5 cm in size. The flowers are reddish or purple. Despite numerous attempts, this dwarf species has proved difficult to cultivate, possibly because it requires very cool, moist conditions and snow cover for part of the year.
