Lower Peninsula Of Michigan
The Lower Peninsula of Michigan – also known as Lower Michigan – is the larger, southern and less elevated of the two major landmasses that make up the U.S. state of Michigan; the other being the Upper Peninsula, which is separated by the Straits of Mackinac. It is surrounded by water on all sides except its southern border, which it shares with Indiana and Ohio. Although the Upper Peninsula is commonly referred to as "the U.P.", it is uncommon for the Lower Peninsula to be called "the L.P." Because of its recognizable shape, the Lower Peninsula is nicknamed "the mitten", with the eastern region identified as "The Thumb". This has led to several folkloric creation myths for the area, one being that it is a handprint of Paul Bunyan, a giant lumberjack and popular European-American folk character in Michigan. When asked where they live, Lower Peninsula residents may hold up their right palm and point to a spot on it to indicate the location. The peninsula is sometimes divide ...

The Detroit News
''The Detroit News'' is one of the two major newspapers in the U.S. city of Detroit, Michigan. The paper began in 1873, when it rented space in the rival ''Detroit Free Press'' building. ''The News'' absorbed the '' Detroit Tribune'' on February 1, 1919, the ''Detroit Journal'' on July 21, 1922, and on November 7, 1960, it bought and closed the faltering ''Detroit Times''. However, it retained the ''Times building, which it used as a printing plant until 1975, when a new facility opened in Sterling Heights. The ''Times'' building was demolished in 1978. The street in downtown Detroit where the Times building once stood is still called "Times Square." The Evening News Association, owner of ''The News'', merged with Gannett in 1985. At the time of its acquisition of ''The News'', Gannett also had other Detroit interests, as its outdoor advertising company, which ultimately became Outfront Media through a series of mergers, operated many billboards across Detroit and the surro ...

Species At Risk Act
The ''Species at Risk Act'' (SARA) (the ''Act'') is a piece of Canadian federal legislation which became law in Canada on December 12, 2002. It is designed to meet one of Canada's key commitments under the International Convention on Biological Diversity. The goal of the ''Act'' is to prevent wildlife species in Canada from disappearing by protecting endangered or threatened organisms and their habitats. It also manages species which are not yet threatened, but whose existence or habitat is in jeopardy. SARA defines a method to determine the steps that need to be taken in order to help protect existing relatively healthy environments, as well as recover threatened habitats, although timing and implementation of recovery plans have limitations. It identifies ways in which governments, organizations, and individuals can work together to preserve species at risk and establishes penalties for failure to obey the law. The ''Act'' designates COSEWIC, an independent committee of wildli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Committee On The Status Of Endangered Wildlife In Canada
The Committee on the Status of Endangered Wildlife in Canada (COSEWIC, French: Comité sur la situation des espèces en péril au Canada, COSEPAC) is an independent committee of wildlife experts and scientists whose "raison d'être is to identify species at risk" in Canada. It designates the conservation status of wild species. It was established in 1977 to provide a single, scientifically sound classification of wildlife species at risk of extinction. In the 2002 Species at Risk Act, COSEWIC was appointed as the body to identify and assess a species status. Although the status assigned by COSEWIC is not legally binding, it does report its results to the government and the public. The report is influential toward the addition of species to the List of Wildlife Species at Risk by the Minister of the Environment. Risk categories By December 2013 there were "686 wildlife species in various COSEWIC risk categories, including 196 Special Concern (SC), 166 Threatened (T), 302 Endang ...

Endangered Species Act
The Endangered Species Act of 1973 (ESA or "The Act"; 16 U.S.C. § 1531 et seq.) is the primary law in the United States for protecting imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation"."Tennessee Valley Authority v. Hill" 437 U.S. 153 (1978) Retrieved 24 November 2015. The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed.

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. Overgrazing can be reversed or prevented by removing grazers in order to give plants time to recover between grazing events. Successful planned grazing strategies have been support in the American bison of the Great Plains, or migratory Wildebeests of the African savann ...

Graminoid
In botany and ecology, graminoid refers to a herbaceous plant with a grass-like morphology, i.e. elongated culms with long, blade-like leaves. They are contrasted to forbs, herbaceous plants without grass-like features. The plants most often referred to include the families Poaceae (grasses in the strict sense), Cyperaceae (sedges), and Juncaceae (rushes). These are not closely related but belong to different clades in the order Poales. The grasses (Poaceae) are by far the largest family with some 12,000 species. Besides their similar morphology, graminoids share the widespread occurrence and often dominance in open habitats such as grasslands or marshes. They can however also be found in the understory of forests. Sedges and rushes tend to prefer wetter habitats than grasses.

The Dakotas
The Dakotas is a collective term for the U.S. states of North Dakota and South Dakota. It has been used historically to describe the Dakota Territory, and is still used for the collective heritage, culture, geography, fauna, sociology, economy, and cuisine among the two states. Etymology The name Dakota refers to the Dakota people. History The territory now known as the Dakotas includes a large portion of the ancestral land of Native American tribes, in particular various tribes of Sioux such as the Dakota people, also known as the Santee Sioux. The United States government stakes its claim to the land through the Louisiana Purchase and Rupert's Land accusation. The region historically involved a complex series of conflicts between the US government and Native American tribes (and among themselves). For a while the region consisted of the Minnesota and Nebraska territories until in 1861, the US government formed the Dakota Territory, which included both the modern states ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hesperiinae
Grass skippers or banded skippers are butterflies of the subfamily Hesperiinae, part of the skipper family, Hesperiidae. The subfamily was established by Pierre André Latreille in 1809. Description and distribution With over 2,000 described species, this is the largest skipper butterfly subfamily and occurs worldwide except in New Zealand. About 50 percent of grass skippers live in the Neotropics. 137 species are native to North America. Around 38 species are native to Australia. Genera ''Ochlodes'' and ''Hesperia'' exist exclusively in the Holarctic. They are usually orange, rust, or brown in colour and have pointed forewings. Many species have dark markings or black stigmas on their forewings. Most members of this subfamily have an oval antenna club with an apiculus on the tip, although '' Carterocephalus'' and '' Piruna'' do not. The antennae generally has a sharp bend. Hesperiinae larvae feed on many different types of grasses and sedges and palms, though some species are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
