Acris Blanchardi
Blanchard's cricket frog (''Acris blanchardi'') is a species of frog in the family Hylidae. It is a small, dark colored frog that is threatened or endangered in Michigan, Wisconsin, and Minnesota. Studies have been done to see why the population of the frog is beginning to decrease in those states. Blanchard's cricket frogs are commonly found in wetlands, ponds, and/or near row crop agriculture. The average life span for this frog is about one year, which is why the species is considered to be short-lived. Little is known about the interactions and basic ecology, even though populations are decreasing. Blanchard's cricket frog was formerly considered to be a subspecies of the northern cricket frog. Description Blanchard's cricket frogs are a type of aquatic tree frogs in North America. They have warty skin that is usually brown, gray, tan, or olive green, with darker bands of color on the legs. Their skin is also heavily vascularized, which allows substances to get into their bod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Harper (biologist)
Francis Harper (17 November 1886 – 17 November 1972) was an American naturalist known for the study of the 18th-century American naturalists John and William Bartram. His research included studies of the Okefenokee Swamp and fieldwork in the north eastern United States and in northern Canada, and authored new combinations for two species originally described by William Bartram, ''Garberia heterophylla'' and '' Roystonea elata''. Biography Harper received an A.B. in 1914 and a Ph.D. in 1925 from Cornell University. He taught briefly at Swarthmore College, but beyond that he worked for museums, government agencies and research agencies. In 1914 Harper made his first trip to northern Canada on an expedition to Lake Athabasca working as a zoologist for the Geological Survey of Canada. Between 1917 and 1919 Harper served as a rodent control officer in France with the United States Army's 79th Division. He returned to Athabasca in 1920, Nueltin Lake in southern Keewatin in ...

Colorado
Colorado (, other variants) is a state in the Mountain West subregion of the Western United States. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the eighth most extensive and 21st most populous U.S. state. The 2020 United States census enumerated the population of Colorado at 5,773,714, an increase of 14.80% since the 2010 United States census. The region has been inhabited by Native Americans and their ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. "''Colorado''" is the Spanish adjective meaning "ruddy", the color of the Fountain Formation outcroppings found up and down the Front Range of the Rocky Mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulyss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Great Lakes Region (North America)
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Fauna Of The United States
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of The United States
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Immune System
The immune system is a network of biological processes that protects an organism from diseases. It detects and responds to a wide variety of pathogens, from viruses to parasitic worms, as well as cancer cells and objects such as wood splinters, distinguishing them from the organism's own healthy tissue. Many species have two major subsystems of the immune system. The innate immune system provides a preconfigured response to broad groups of situations and stimuli. The adaptive immune system provides a tailored response to each stimulus by learning to recognize molecules it has previously encountered. Both use molecules and cells to perform their functions. Nearly all organisms have some kind of immune system. Bacteria have a rudimentary immune system in the form of enzymes that protect against virus infections. Other basic immune mechanisms evolved in ancient plants and animals and remain in their modern descendants. These mechanisms include phagocytosis, antimicrobial pe ...

Lower Peninsula
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 divided ...
