Spilopsyllus Cuniculi
''Spilopsyllus cuniculi'', the rabbit flea, is a species of flea in the Family (biology), family Pulicidae. It is an external Parasitism, parasite of rabbits and hares and is occasionally found on cats and dogs and also certain seabirds that nest in burrows. It can act as a Vector (epidemiology), vector for the virus that causes the rabbit disease myxomatosis. Description The rabbit flea is about long and a dark brown colour. It is laterally compressed, has three pairs of legs and no wings. Its head is held at an angle to its body and its mouthparts are adapted for piercing the skin of its host and sucking its blood. It has a pronotal comb or row of spines just behind the head and a genal comb of spines below the head and these help to distinguish it from other species of flea. It is a sedentary flea that stays feeds of a single location for a long period of time. ''S. cuniculi'' have adapted to feed on the ears of rabbits, which are in rich in blood supply. Host species ''S. c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flea
Flea, the common name for the order (biology), order Siphonaptera, includes 2,500 species of small flightless insects that live as external parasites of mammals and birds. Fleas live by hematophagy, ingesting the blood of their hosts. Adult fleas grow to about long, are usually dark in color, and have bodies that are "flattened" sideways or narrow, enabling them to move through their hosts' fur or feathers. They lack wings; their hind legs are extremely well adapted for jumping. Their claws keep them from being dislodged, and their mouthparts are adapted for piercing skin and sucking blood. Some species can leap 50 times their body length, a feat second only to jumps made by another group of insects, the superfamily (taxonomy), superfamily of froghoppers. Flea larvae are worm-like, with no limbs; they have chewing mouthparts and feed on organic debris left on their hosts' skin. Genetic evidence indicates that fleas are a specialised lineage of parasitic scorpionflies (Mecopte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manx Shearwater
The Manx shearwater (''Puffinus puffinus'') is a medium-sized shearwater in the seabird family Procellariidae. The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century. Puffin is an Anglo-Norman language, Anglo-Norman word (Middle English ''pophyn'') for the Curing (food preservation), cured carcasses of nestling shearwaters. The Atlantic puffin acquired the name much later, possibly because of its similar nesting habits. Taxonomy The shearwaters form part of the family Procellariidae, a widespread group containing nearly 100 species of medium to large seabirds. They have long, narrow wings and the characteristic “tube nose”. Although it was considered a monotypic species, recently an endemic subspecies for the Canary Islands has been proposed ''P. puffinus canariensis''. The large genus ''Puffinus'' includes several species formerly considered to be subspecies of the Manx shearwater, including the yelkouan shea ...

Pathogen
In biology, a pathogen (, "suffering", "passion" and , "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a Germ theory of disease, germ. The term ''pathogen'' came into use in the 1880s. Typically, the term ''pathogen'' is used to describe an ''infectious'' microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. Small animals, such as helminths and insects, can also cause or Transmission (medicine), transmit disease. However, these animals are usually referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while parasitology refers to the scientific study of parasites and the organisms that host them. There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time ...

Bacterium
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit the air, soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in mutualistic, commensal and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bartonella Alsatica
''Bartonella alsatica'' is a bacterium. Like other'' Bartonella'' species, it can cause disease in animals. It is small, aerobic, oxidase-negative, and Gram-negative. Its rod-like cells were localized within wild rabbit erythrocytes when first described. The type strain is IBS 382T (= CIP 105477T). It is associated with cases of lymphadenitis and endocarditis Endocarditis is an inflammation of the inner layer of the heart, the endocardium. It usually involves the heart valves.

Greenwood Publishing Group
Greenwood Publishing Group, Inc. (GPG) was an educational and academic publisher (middle school through university level) which was part of ABC-Clio. Since 2021, ABC-Clio and its suite of imprints, including GPG, are collectively imprints of British publishing house Bloomsbury Publishing. The Greenwood name stopped being used for new books in 2023. Established in 1967 as Greenwood Press, Inc., and based in Westport, Connecticut, GPG published reference works under its Greenwood Press imprint; and scholarly, professional, and general-interest books under its related imprint, Praeger Publishers (). Also part of GPG was Libraries Unlimited, which published professional works for librarians and teachers.

Ross Piper
Ross Piper is a British zoologist, entomologist, and explorer. Biography Piper's fascination by animals began at a young age through early encounters with a violet ground beetle and the caterpillar of an elephant hawk moth. This early interest led to a degree in zoology from Bangor University and a PhD in insect ecology from the University of Leeds. Piper has travelled widely in Europe, the Americas, Africa and Southeast Asia, searching for interesting and elusive beasts. Although his focus is arthropods, the sheer diversity of animal forms and lifestyles is a continual source of fascination. In 2015 he was awarded the Alumnus of the Year award by Bangor University and has since become a member of their alumni advisory board. He is also a student mentor for the University of Leeds and a Fellow of the Royal Geographical Society. He is currently a visiting research fellow at the University of Leeds and a visiting fellow at the University of Essex. His current projects include a ...

Birth
Birth is the act or process of bearing or bringing forth offspring, also referred to in technical contexts as parturition. In mammals, the process is initiated by hormones which cause the muscular walls of the uterus to contract, expelling the fetus at a developmental stage when it is ready to feed and breathe. In some species, the offspring is precocial and can move around almost immediately after birth but in others, it is altricial and completely dependent on parenting. In marsupials, the fetus is born at a very immature stage after a short gestation and develops further in its mother's womb Pouch (marsupial), pouch. It is not only mammals that give birth. Some reptiles, amphibians, fish and invertebrates carry their developing young inside them. Some of these are Ovoviviparity, ovoviviparous, with the eggs being hatched inside the mother's body, and others are Viviparity, viviparous, with the embryo developing inside their body, as in the case of mammals.

Hormone
A hormone (from the Ancient Greek, Greek participle , "setting in motion") is a class of cell signaling, signaling molecules in multicellular organisms that are sent to distant organs or tissues by complex biological processes to regulate physiology and behavior. Hormones are required for the normal development of animals, plants and fungi. Due to the broad definition of a hormone (as a signaling molecule that exerts its effects far from its site of production), numerous kinds of molecules can be classified as hormones. Among the substances that can be considered hormones, are eicosanoids (e.g. prostaglandins and thromboxanes), steroids (e.g. Estrogen, oestrogen and brassinosteroid), amino acid derivatives (e.g. epinephrine and auxin), protein or peptides (e.g. insulin and CLE peptides), and gases (e.g. ethylene and nitric oxide). Hormones are used to communicate between organ (anatomy), organs and Tissue (biology), tissues. In vertebrates, hormones are responsible for regulating ...

Atlantic Puffin
The Atlantic puffin ('), also known as the common puffin, is a species of seabird in the auk family (biology), family. It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin being found in the northeastern Pacific. The Atlantic puffin breeds in Russia, Iceland, Ireland, Great Britain, Britain, Norway, Greenland, Newfoundland and Labrador, Nova Scotia, and the Faroe Islands, and as far south as Maine in the west and France in the east. It is most commonly found in the Westman Islands, Iceland. Although it has a large population and a wide range, the species has declined rapidly, at least in parts of its range, resulting in it being rated as Vulnerable species, vulnerable by the IUCN. On land, it has the typical upright stance of an auk. At sea, it swims on the surface and feeds on zooplankton, small fish, and crabs, which it catches by diving underwater, using its wings for propulsion. This puffin has a black crown and bac ...

Host (biology)
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasite, parasitic, a mutualism (biology), mutualistic, or a commensalism, commensalist ''guest'' (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cell (biology), cells harbouring pathogenic (disease-causing) viruses, or a Fabaceae, bean plant hosting mutualistic (helpful) Rhizobia, nitrogen-fixing bacteria. More specifically in botany, a host plant supplies nutrient, food resources to micropredators, which have an evolutionarily stable strategy, evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. Symbiosis Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
