*  Oxygen isotope analysis of multiple, single ostracod valves as a proxy for combined variability in seasonal temperature and...
Paleoclimate studies in lakes typically use oxygen isotopic ratios in samples that consist of multiple ostracod specimens, to obtain an average δ18O value that reflects the mean temperature and δ18O of lake water over the life spans of the combined individuals measured. This approach overlooks potential information on seasonal climate variability that is recorded in the single valves of short-lived ostracods. Here we estimate seasonal variability in ostracod δ18O by measuring 10-30 individual carapaces of Cyprideis torosa in selected stratigraphic levels of a sediment core from paleolake Riwasa in Haryana, India. The mean δ18O values of ostracod populations show a general decrease from 9.6 to 8.3 kyr BP, which was interpreted previously as resulting from strengthening of the Indian summer monsoon during the early Holocene. The δ18O measurements of single ostracods within samples show a large range (up to ~15 ‰) and standard deviation (up to ±3.3), suggesting high seasonal variability in ...

Maxillopoda. Ostracoda. Malacostraca. Crustaceans (Crustacea) form a very large group of arthropods, usually treated as a subphylum, which includes such familiar animals as crabs, lobsters, crayfish, shrimp, krill and barnacles. The 50,000 described species range in size from Stygotantulus stocki at 0.1 mm (0.004 in), to the Japanese spider crab with a leg span of up to 12.5 ft (3.8 m) and a mass of 44 lb (20 kg). Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates by the possession of biramous (two-parted) limbs, and by the nauplius form of the larvae.. Most crustaceans are free-living aquatic animals, but some are terrestrial (e.g. woodlice), some are parasitic (e.g. fish lice, tongue worms) and some are sessile (e.g. barnacles). The group has an extensive ...

*  Triops - Wikipedia
The name Triops comes from the Greek τρία (tría) meaning "three" and ὤψ (ops) meaning "eye".[7] The head of Triops longicaudatus bears a pair of dorsal compound eyes that lie close to each other and are nearly fused together. The compound eyes are generally sessile (not stalked). In addition, there is a naupliar ocellus (the "third eye") between them. The compound eyes are on the surface of the head, but the ocellus is deep within the head. All the eyes, however, are easily visible through the shell covering of the head.. Franz von Paula Schrank was the first author to use the genus name Triops,[8] coining it in his 1803 work on the fauna of Bavaria. Their German name was Dreyauge, which means 'three-eye' in English. He collected and described specimens from the same locality in Regensburg from which Schäffer, another naturalist who had studied the Notostraca, obtained his specimens in the 1750s. However, other authors, starting with Louis Augustin Guillaume Bosc, had adopted the genus ...

However, despite their importance, only a few genetic studies have been conducted so far in ostracoda due to isolation of in sufficient amounts of DNA. We present a simple, efficient and cost-effective total DNA extraction protocol from freshwater ostracods for PCR amplification. Total DNA was extracted from the four freshwater ostracods; Heterocypris incongruens, Cypridopsis vidua, Eucypris virens and Herpetocypris chevreuxi. We also compared the performance of our protocol with two manual DNA extraction protocols (HotSHOT, Chelex-100) and a commercial kit (Highpure PCR template preparation kit-Roche). The success of the isolation protocol was tested ...

*  Crustacea - Simple English Wikipedia, the free encyclopedia
The Crustacea are a subphylum of pancrustaceans with 50,000 described species. They are part of the phylum Arthropoda. Crustaceans include crabs, lobsters, crayfish, shrimp, krill and barnacles. They are relatives of insects. If the Arthropods are regarded as a superphylum, then the insects and crustaces would be phyla. (see List of animal phyla). The group has an extensive fossil record, reaching back to the Cambrian.. Most crustaceans are aquatic, mostly marine. Some have moved onto land permanently. Crustaceans that live on land include some crabs, and woodlice. Crustacea range in size from a parasite 0.1mm long, to the Japanese spider crab with a leg span of up to 14 ft (4.3 m) and a mass of 44 lb (20 kg). The North Atlantic lobster can weigh more than 40 pounds.. Most crustaceans are mobile, but some become sessile after their larval stage. Barnacles become attached to ...

Los pancrustáceos (Pancrustacea) son un taxón propuesto para comprender todos los crustáceos y hexápodos. Esta agrupación es contraria a la hipótesis de los atelocerados en la que los miriápodos y hexápodos son un clado y los crustáceos están más alejados de ellos. El taxón monofilético de los pancrustáceos está apoyado por numerosos estudios moleculares, en los que los crustáceos acontecen un grupo parafilético con los insectos (lo que significa que los insectos han derivado de antepasados crustáceos).[1]​[2]​[3]​[4]​ J.

For the ostracode analysis, a total of 87 samples were selected at intervals of ca. 10 cm between 0 to 865 cm depth. Due to the lack of ostracode valves, the lower part (980 865 cm) of the sediment sequence was not included in the study. The samples were oven dried at 50 °C and weighed to determine their dry weights. Sediments were disintegrated by soaking in water for 2 3 days and washed through two sieves of 0.063 mm and 0.425 mm to collect sediment with ostracode valves and eliminate the finer sediments. The residues were oven dried at 50 °C and examined under an Olympus SZX FOF stereoscopic microscope to identify the species and calculate their abundance according to the descriptions provided by Van Morkhoven (1963), Delorme (1971 a, b, c), Forester (1985) and Carreño (1990). The total ostracode abundance in each sample was calculated by adding the number of adult and juvenile valves of all the observed species. The number of adult valves of each species was counted in 10 g of dry ...
