Darcythompsoniidae
Darcythompsoniidae is a family of copepods, containing four genera. Members of the family have a very wide distribution throughout the tropics, where they live in rotting mangrove leaves. They lack egg sacs and are thought to lay their eggs directly into the leaf litter Plant litter (also leaf litter, tree litter, soil litter, litterfall or duff) is dead plant material (such as leaves, bark, needles, twigs, and cladodes) that have fallen to the ground. This detritus or dead organic material and its constituent .... '' Darcythompsonia'' and '' Kristensenia'' are both large-bodied, while '' Leptocaris'' species are much smaller.

Harpacticoida
Harpacticoida is an order of copepods, in the subphylum Crustacea. This order comprises 463 genera and about 3,000 species; its members are benthic copepods found throughout the world in the marine environment (most families) and in fresh water (essentially the Ameiridae, Parastenocarididae and the Canthocamptidae). A few of them are planktonic or live in association with other organisms. Harpacticoida represents the second-largest meiofaunal group in marine sediments, after nematodes. In Arctic and Antarctic seas, Harpacticoida are common inhabitants of sea ice. The name Harpacticoida comes from the Greek noun ''harpacticon'' (rapacious predator) and the suffix ''-oid'' (akin to) and means ''reminiscent of a predator'' . Harpacticoids are distinguished from other copepods by the presence of only a very short pair of first antennae. The second pair of antennae are biramous, and the major joint within the body is located between the fourth and fifth body segments. They typically ...

Karl Georg Herman Lang
Karl Georg Herman Lang (21 July 1901 – 14 March 1976) was a Swedish zoologist, specialising in crustaceans, especially harpacticoid copepods and tanaids. He was born in Malmö and gained a doctoral degree from the Lund University in 1924. He spent much of his early career working as a teacher in elementary schools in Eslöv, Lund and Stockholm. From 1947 to 1967, Lang worked at the Swedish Museum of Natural History, eventually reaching the position of head of the Section of Invertebrate Zoology. As well as many papers on Harpacticoida up to 1965, and many papers on Tanaidacea throughout his life, Lang also published on Priapulida and Kinorhyncha, and a single paper on isopod crustaceans. He had few students, and his writings were "painfully detailed" and introduced long names such as '' Paraphyllopodopsyllus'' and '' Pseudoleptomesochrella''. Taxa Karl Lang is commemorated in the genus name '' Karllangia''. Taxa named by Lang include: *Microcerberidea The Microcerberidea are ...

Pabellonia
''Leucocoryne'' (glory-of-the-sun) is a genus of bulbous perennials in the family Amaryllidaceae. The foliage of all species is long and narrow and has an onion-like scent. The blue, white or lilac flowers are held in umbels. The entire genus is endemic to the Republic of Chile in South America. Some species are grown in gardens as ornamentals. They require very well-drained soil and do not tolerate freezing temperatures. ''L. purpurea'', with purple flowers, has gained the Royal Horticultural Society’s Award of Garden Merit. Derivation of genus name The generic name ''Leucocoryne'' is a compound of the Greek elements λευκός ( = ''leucos'' ) "white" and κορυνε ( = ''korune'' ) "club" ( in the sense of cudgel or bludgeon ) - in reference to the pale, club-like, sterile anthers of the flowers. Taxonomy Species Species accepted by The Plant List are listed here (49) although some authorities estimate only 15. # '' Leucocoryne alliacea'' Lindl. # '' Leucocoryne an ...

Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove
A mangrove is a shrub or tree that grows in coastal saline water, saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are ad ...

Egg Sac
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...
