Pseudomys Delicatulus
The little native mouse (''Pseudomys delicatulus''), also known as the delicate mouse, is a species of rodent in the family Muridae. The Kunwinjku of western Arnhem Land call this little creature Kijbuk. It is found in Western Australia, the Northern Territory, Queensland, New South Wales and Papua New Guinea. Description and behaviour The little native mouse has fur that is yellow-brown to grey-brown above and white underneath. It is the smallest of all Australian native mice with a head and body length of 55–75 mm with adults of both sexes being roughly the same in size, weight (6–15 g) and colour. In Arnhem Land, the only place the species has been studied at length, breeding takes place in July and August. Two to four young are born in a grass-lined nesting chamber after a gestation of 28–31 days. At birth the eyes are shut and the ears tightly folded back, they develop quickly and are independent of the mother around four weeks of age. Habitat The speci ...

Termite
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus ''Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Mammals Described In 1842
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...

Rodents Of Australia
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose incisors ...

Pseudomys
''Pseudomys'' is a genus of rodent that contains a wide variety of mice native to Australia and New Guinea. They are among the few terrestrial placental mammals that colonised Australia without human intervention. Natural history This genus contains a number of species with different habits making generalisation difficult. The overall body size varies widely, ranging from 60 to 160 mm. The tail is 60–180 mm and the weight is recorded from 12 to 90 g. They inhabit a wide variety of habitats from rainforests to plains and grasslands. The animals are nocturnal and spend the day in burrows. Food also varies with some species eating seeds, roots and insects while others feed primarily on grasses. The pebble-mound mice are unique in creating mounds of stones around their burrows. Several species of ''Pseudomys'' are threatened due to competition with introduced species and habitat destruction. Several others are probably extinct. Etymology The name ''Pseudomys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seeds
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general meaning that anteda ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Delicate Salt Flat Mouse
The delicate salt flat mouse, ''Salinomys delicatus'', (in Spanish, el ratón delicado de los salares) is a sigmodontine rodent species in the family Cricetidae from South America. It is the only species in the genus ''Salinomys''. Its habitat is scrublands bordering salt flats (such as those of the Salinas Grandes) in the Monte Desert area of central western Argentina at elevations around 400 m. The closest relatives of the species are the chaco mice (''Andalgalomys'').Steppan, S.J.; Ramirez, O.; Banbury, J.; ''et al.'' 2007.
