Assamiidae
Assamiidae are a family of harvestmen with more than 400 described species. It is the third most diverse family of the suborder Laniatores. Name The family name is derived from the Indian province Assam, where the type species of the type genus ('' Assamia westermanni'') was collected. (2007): Assamiidae Sørensen, 1884. In: Pinto-da-Rocha ''et al.'' 2007: 173ff Description These harvestmen range in body length from two to eight millimeters. The length of their legs ranges from four to forty millimeters, though they are usually long. Assamiidae are usually reddish brown to yellow with black mottling and reticulation. Some species have white drawings on the dorsal scutum. Distribution Assamiidae only occur in the Old World, and are completely absent from Madagascar and Europe, with most species found in Africa and southern Asia. Although they are also not found on the Pacific islands, the subfamily Dampetrinae has radiated in Australia, New Guinea, and somewhat in Indonesia. Su ...

List Of Assamiidae Species
This is a list of the described species of the harvestman family Assamiidae. The data is taken from Joel Hallan's Biology Catalog. Many of Roewer's subfamilies are unsupported, as the relationships in this family await further research.Pinto-da-Rocha ''et al.'' 2007: 175 Aburistinae Aburistinae — Roewer, 1935 * '' Aburista'' — Roewer, Yahia Mustafa :* '' Aburista termitarum'' — Roewer, 1935 — Ghana * '' Aburistella'' — Lawrence, 1947 :* '' Aburistella flava'' — Lawrence, 1947 * '' Bancoella'' — Lawrence, 1947 :* '' Bancoella bimaculata'' — Lawrence, 1947 * '' Banconyx'' — Lawrence, 1947 :* '' Banconyx dentichelis'' — Lawrence, 1947 * '' Sokodea'' — Roewer, 1935 :* '' Sokodea caeca'' — Roewer, 1935 * '' Typhlobunellus'' — Roewer, 1927 :* '' Typhlobunellus formicarum'' — Roewer, 1927 :* '' Typhlobunellus platypalpis'' — Lawrence, 1947 * '' Typhloburista'' — Lawrence, 1947 :* '' Typhloburista pusilla'' — Lawrence, 1947 Acacinae Acacinae — ...

Gonyleptoidea
Gonyleptoidea is the most diverse superfamily of the Grassatores. It includes around 2,500 species distributed in the tropics. They are characterized by the simplified male genitalia, with the glans free subapical in the truncus. Gonyleptoidea is the only group of harvestmen to show maternal care of offspring.

Opiliones
The Opiliones (formerly Phalangida) are an order of arachnids colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their phylogenetic position within the Arachnida is disputed; their closest relatives may be the mites (Acari) or the Novogenuata (the Scorpiones, Pseudoscorpiones, and Solifugae). Althou ...

Soil Food Web
The soil food web is the community of organisms living all or part of their lives in the soil. It describes a complex living system in the soil and how it interacts with the environment, plants, and animals. Food webs describe the transfer of energy between species in an ecosystem. While a food chain examines one, linear, energy pathway through an ecosystem, a food web is more complex and illustrates all of the potential pathways. Much of this transferred energy comes from the sun. Plants use the sun’s energy to convert inorganic compounds into energy-rich, organic compounds, turning carbon dioxide and minerals into plant material by photosynthesis. Plant flowers exude energy-rich nectar above ground and plant roots exude acids, sugars, and ectoenzymes into the rhizosphere, adjusting the pH and feeding the food web underground. Plants are called autotrophs because they make their own energy; they are also called producers because they produce energy available for other org ...

Speleology
Speleology is the scientific study of caves and other karst features, as well as their make-up, structure, physical properties, history, life forms, and the processes by which they form (speleogenesis) and change over time (speleomorphology). The term ''speleology'' is also sometimes applied to the recreational activity of exploring caves, but this is more properly known as ''caving'', ''potholing'' (British English), or ''spelunking''. Speleology and caving are often connected, as the physical skills required for ''in situ'' study are the same. Speleology is a cross-disciplinary field that combines the knowledge of chemistry, biology, geology, physics, meteorology, and cartography to develop portraits of caves as complex, evolving systems. History Before modern speleology developed, John Beaumont wrote detailed descriptions of some Mendip caves in the 1680s. The term speleology was coined by Émile Rivière in 1890. Prior to the mid-nineteenth century the scientific valu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sri Lanka
