Ussuri Tube-nosed Bat
The Ussuri tube-nosed bat (''Murina ussuriensis'') is a species of vesper bat in the family Vespertilionidae. It is threatened by habitat loss. It is the only species of bat that hibernates in snowbanks. Taxonomy and etymology It was described as a new species in 1913 by Russian zoologist Sergey Ognev. Its species name "''ussuriensis''" comes from Ussuriland. The holotype had been collected in Ussuriland by Nikolaus Ikonnikov (also spelled Ikonnikoff). In 1951, Ellerman and Morrison-Scott classified it as a subspecies of the little tube-nosed bat with a trinomen of ''Murina aurata ussuriensis''. The population in Japan is sometimes referred to as ''Murina silvatica''. Description It is a moderately small member of its genus, with a forearm length of . Its head and body length is , while its tail is . Its fur is soft and short. Fur on the back is tricolored, with reddish brown tips, pale middles, and dark roots. The belly fur is pale and grayish in comparison. The tops of its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hymenolepididae
__NOTOC__ The Hymenolepididae are family of cyclophyllid tapeworms. Their characteristic feature is the small number of testes (one to four). The unilateral genital pores and large external seminal vesicle allow for easy recognition. Most species are small, transparent, and easy to study. The family contains over 90 genera with over 900 species, having as their definitive host birds (c. 700 species) or mammals (about 250 species). Most reside in the intestines of their definitive hosts. The majority of species with known lifecycles have arthropods as intermediate hosts. As human parasites The family Hymenolepididae has only two species which infects humans: the disease hymenolepiasis is caused by ''Hymenolepis nana'' and '' H. diminuta'', which are sometimes classified in the genus ''Rodentolepis''. Most cases of hymenolepiasis are caused by ''H. nana''. It occurs worldwide, but in temperate climates, children and people living in institutions are more likely to be infected. ...

Endoparasites
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Maturity
Sexual maturity is the capability of an organism to reproduce. In humans it might be considered synonymous with adulthood, but here puberty is the name for the process of biological sexual maturation, while adulthood is based on cultural definitions. Most multicellular organisms are unable to sexually reproduce at birth (animals) or germination (e.g. plants): depending on the species, it may be days, weeks, or years until they have developed enough to be able to do so. Also, certain cues may trigger an organism to become sexually mature. They may be external, such as drought (certain plants), or internal, such as percentage of body fat (certain animals). (Such internal cues are not to be confused with hormones, which directly produce sexual maturity – the production/release of those hormones is triggered by such cues.) Role of reproductive organs Sexual maturity is brought about by a maturing of the reproductive organs and the production of gametes. It may also be accompanied ...

Philopatric
Philopatry is the tendency of an organism to stay in or habitually return to a particular area. The causes of philopatry are numerous, but natal philopatry, where animals return to their birthplace to breed, may be the most common. The term derives from the Greek roots ''philo'', "liking, loving" and ''patra'', "fatherland", although in recent years the term has been applied to more than just the animal's birthplace. Recent usage refers to animals returning to the same area to breed despite not being born there, and migratory species that demonstrate site fidelity: reusing stopovers, staging points, and wintering grounds. Some of the known reasons for organisms to be philopatric would be for mating (reproduction), survival, migration, parental care, resources, etc.. In most species of animals, individuals will benefit from living in groups, because depending on the species, individuals are more vulnerable to predation and more likely to have difficulty finding resources and food. ...

Polar Bear
The polar bear (''Ursus maritimus'') is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the largest extant bear species, as well as the largest extant land carnivore. A boar (adult male) weighs around , while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar be ...

Fission–fusion Society
In ethology, a fission–fusion society is one in which the size and composition of the social group change as time passes and animals move throughout the environment; animals merge into a group (fusion)—e.g. sleeping in one place—or split (fission)—e.g. foraging in small groups during the day. For species that live in fission–fusion societies, group composition is a dynamic property. The change in composition, subgroup size, and dispersion of different groups are 3 main elements of a fission-fusion society. This social organization is found in several primates, elephants, cetaceans, ungulates, social carnivores, some birds and some fish. Species Fission-fusion societies occur among many different species of primates (e.g. chimpanzees, orangutans, and humans), elephants (e.g. forest elephants, African elephants), and bats (e.g. northern long-eared bats). The change in composition, subgroup size, and dispersion of different groups are 3 main elements of a fission-fusion s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maternity Colony (bats)
A maternity colony refers to a temporary association of reproductive female bats for giving birth to, nursing, and weaning their pups. The colonies are initiated by pregnant bats. After giving birth, the colony consists of the lactating females and their offspring. After weaning, juveniles will leave the maternity colony, and the colony itself will break apart. The size of a maternity colony is highly variable by species, with some species forming colonies consisting of ten or fewer individuals, while the largest maternity colony in the world in Bracken Cave is estimated to have over 15 million bats. Benefits of a maternity colony Maternity colonies are especially prevalent in temperate regions due to the thermal benefits of roosting with other individuals.Dietz, M., & Kalko, E. K. (2006).

Colony (biology)
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be modular organisms. Unitary organisms have determinate development (set life stages) from zygote to adult form and individuals or groups of individuals (colonies) are visually distinct. Modular organisms have indeterminate growth forms (life stages not set) through repeated iteration of genetically identical modules (or individuals), and it can be diffic ...

Ficus Superba
''Ficus superba'', also known as sea fig or deciduous fig, is a hemiepiphytic tree of genus ''Ficus''. It is one of the species known as banyans or "strangler figs" because of its potential to grow as a hemi-epiphyte and eventually progress to the strangling habit of species in this subgenus. It is, however, not an obligate hemi-epiphyte and can be found growing as single stemmed trees in forests. It is found in Japan, Taiwan, Australia, and China, as well as various parts of Southeast Asia, such as Thailand, Vietnam, Java, Kalimantan, the Lesser Sunda Islands, Moluccas, Seram Island, and Peninsular Malaysia. Varieties and synonyms The variety ''Ficus superba var. henneana'' grows in Australia where it may reach 35 metres tall. Other varieties have now been reclassified as synonyms: * ''F. superba'' var. ''alongensis'' (Gagnep.) Corner is a synonym of ''Ficus alongensis'' Gagnep. * ''F. superba'' var. ''japonica'' Miq. is a synonym of ''Ficus subpisocarpa ''Ficus subpisoca ...
