A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
Flagellate EUKARYOTES, found mainly in the oceans. They are characterized by the presence of transverse and longitudinal flagella which propel the organisms in a rotating manner through the water. Dinoflagellida were formerly members of the class Phytomastigophorea under the old five kingdom paradigm.

Rapid evolution of sessility in an endemic species flock of the freshwater bivalve Corbicula from ancient lakes on Sulawesi, Indonesia. (1/11)

The fauna of ancient lakes frequently contains taxa with highly derived morphologies that resulted from in situ radiation of lacustrine lineages with high antiquity. We employed a molecular mtDNA phylogeny to investigate this claim for corbiculid freshwater bivalves in two ancient lake systems on the Indonesian island Sulawesi. Among the otherwise mobile corbiculid species flock, only one taxon, Posostrea anomioides, in the ancient Lake Poso exhibits a unique habit, i.e. cementing one valve to the substrate. Our data show that Corbicula on Sulawesi is polyphyletic, with the endemic riverine taxa in terminal position, and the lacustrine species flock being paraphyletic. Surprisingly, Posostrea is not confirmed as a genus distinct from Corbicula and genetic distances suggest a rather recent origin from the only other corbiculid species endemic to Lake Poso, the non-cementing Corbicula possoensis. While the cementing anomioides, despite its unique behavioural and morphological characteristics, clusters together with non-sessile Corbicula species, the latter exhibit strong genetic distances in the absence of morphological disparity and fall into several genetically rather distinct clades. These findings suggest that developmental plasticity of animals in ancient lakes rather than the antiquity of lineages might account for the unique morphology of some species.  (+info)

A novel ornithine-containing tripeptide isolated from the extract of the brackish-water bivalve Corbicula japonica. (2/11)

Previous studies have demonstrated that frozen preparations of the brackish-water bivalve Corbicula japonica significantly increase the content of free ornithine found in its extracts. Here we report a novel ornithine-containing tripeptide commonly found in C. japonica, which is believed to be the source of increased free ornithine. The new peptide, named acorbine, was isolated from extracts of this bivalve obtained using ultra-filtration and gel permeation chromatography. Acorbine is comprised of N(2)-[N(2)-(beta-alanyl)-L-ornithyl]-L-ornithine as determined by amino acid composition analysis, N- and C-terminal amino acid analyses, proton nuclear magnetic resonance spectrometry, and chirality analysis of the ornithine residue. The total amount of beta-alanine and ornithine in the extract remained constant regardless of the temperature at which the bivalve was processed. The amount of free beta-alanine and ornithine increased significantly when the bivalve was frozen, with a corresponding decrease in peptidic beta-alanine and ornithine. The results suggest that changing the growth conditions triggers tripeptide proteolysis within the bivalve, which ultimately manifests in increased free beta-alanine and ornithine.  (+info)

Polychlorinated biphenyl exposure causes gonadal atrophy and oxidative stress in Corbicula fluminea clams. (3/11)

Polychlorinated biphenyls (PCBs) are widespread environmental contaminants that have been linked to oxidative and other toxic effects in both humans and wildlife. Due to recent environmental health concerns at a PCB contaminated Superfund site near Raleigh, NC, we used a common clam species (Corbicula fluminea) as surrogates to isolate the effects of PCBs on threatened bivalves native to the region. Under controlled laboratory conditions, clams were exposed to 0, 1, 10, or 100 ppb Aroclor 1260 in the ambient water for 21 days. Measured biomarkers spanned a range of effective levels of biological organization including low molecular weight antioxidants, lipid-soluble antioxidants, and whole tissue radical absorption capacity. These data were augmented by use of histological evaluation of whole samples. Aroclor 1260 significantly increased reduced glutathione (GSH) and total protein concentrations at all treatments levels. Significant decreases were measured in all treatments in gamma -tocopherol and total oxidant scavenging capacity (TOSC) and alpha -tocopherol values in the 100 ppb exposure. Histologically, Aroclor 1260 caused significant gonadal atrophy, effacement of gonad architecture with accumulations of Brown cells, and inflammation and necrosis in digestive glands and foot processes. Our results indicate that oxidative mechanisms play a significant role in the decreased health of these clams due to exposure to Aroclor 1260. The changes in the gonads of exposed clams suggest that a serious threat to bivalve reproduction exists due to PCB exposure.  (+info)

Bioaccumulation and metabolism of [14C]bisphenol A in the brackish water bivalve Corbicula japonica. (4/11)

The brackish water bivalve mollusk Corbicula japonica was exposed to brackish water containing approximately 9 microg/l [(14)C]bisphenol A (BPA) for 168 h (the uptake phase), and subsequently transferred to clean brackish water for 144 h (the depuration phase) under semi-static conditions. Mono and disulfate conjugates of BPA were detected in the bivalves as major metabolites. At the end of the uptake phase, the visceral mass contained the highest (14)C-concentration, and the monosulfate conjugate of BPA was a major metabolite in the visceral mass. These data suggest that the visceral mass is the major tissue/organ to take up and metabolize BPA in these bivalves. The BPA concentration in the bivalves readily reached steady state during the uptake phase and immediately decreased in the depuration phase. The accumulation and elimination rates of the mono and disulfate conjugates of BPA were slower than those of BPA.  (+info)

ABSTRACT. Xenophyophorea are giant deep-sea rhizopodial protists of enigmatic origins. Although species were described as Foraminifera or sponges in the early literature, the xenophyophoreans are currently classified either as a class of Rhizopoda or an independent phylum. To establish the phylogenetic position of Xenophyophorea, we analysed the small subunit (SSU) rRNA gene sequence of Syringammina corbicula Richardson, a newly described xenophyophorean species from the Cape Verde Plateau. The SSUrDNA analyses showed that S. corbicula is closely related to Rhizammina algaeformis, a tubular deep-sea foraminiferan. Both species branch within a group of monothalamous (single-chambered) Foraminifera, which include also such agglutinated genera as Toxisarcon, Rhabdammina, and Saccammina, and the organic-walled genera Gloiogullmia and Cylindrogullmia. Our results are congruent with observations of similar cytoplasmic organisation in Rhizammina and Syringammina. Thus, the Xenophyophorea appear to be a ...

Fact﻽: Bees have a slightly concave area on the tibia of their hind legs surrounded by hairs. These are called corbiculae, or pollen baskets. As the bee is foraging, it uses its forelegs to brush the pollen from its body back into the corbiculae where it is trapped. You can often see this -- look for (usually) yellow lumps on the bees hind legs. (source) ...

Its hard to imagine mussels suddenly disappearing from a place like this, but Haag has grown accustomed to seeing it happen. Hell visit a place last documented to have a healthy population of mussels and instead find only dead shells mixed with old mussels past the reproductive stage. Its only a matter of time before it becomes a shell graveyard.. In his years of research and considering other peer-reviewed work, Haag says he believes only two things could be the cause of the decline: either a disease that has not yet been identified or the Corbicula (Asian clam), an invasive species that has been thought to be harmless for decades.. He hopes an answer will help save these creatures whose benefits are just now being understood and, in some cases, harnessed by humans. There is now a discussion about putting a monetary figure on mussels.. A paper on the topic was released in March 2018 in Hydrobiologia, an international journal of aquatic sciences. The authors called for more research on the ...

The process of androgenesis allows a mature plant embryo to form from a reduced, or immature, pollen grain.[15] Androgenesis usually occurs under stressful conditions.[15] Embryos that result from this mechanism can germinate into fully functional plants. As mentioned, the embryo results from a single pollen grain. Pollen grains consists of three cells - one vegetative cell containg two generative cells. According to Maraschin et al., androgenesis must be triggered during the asymmetric division of microspores.[15] However, once the vegetative cell starts to make starch and proteins, androgenesis can no longer occur. Maraschin et al., indicates that this mode of embryogenesis consists of three phases. The first phase is the acquisition of embryonic potential, which is the repression of gametophyte formation, so that the differentiation of cells can occur. Then during the initiation of cell divisions, multicellular structures begin to form, which are contained by the exine wall. The last step of ...
Most of the fish research at SEAFDEC AQD in 1992-1994 was on milkfish. Studies were conducted on year-round spawning through hormonal or environmental manipulation; optimum lipid and protein levels and ration size for captive broodstock; and the influence of spawner age on reproductive performance. The economics of hatchery operations, alone or integrated with broodstock as a commercial enterprise, was assessed. Mass production of larvae was refined with the use of commercial or SEAFDEC-formulated larval diets. Alternative rearing schemes in large tanks and ponds were tried. Hatcheryproduced and wild-caught larvae were compared in terms of growth and production in experimental nursery and grow-out ponds. Supplemental diets for brackishwater grow-out culture were formulated. Studies on broodstock management of grouper Epinephelus spp. included lipid enrichment of the diet and hormonal induction of sex inversion. Seed production techniques were developed but survival rates were low. Grouper ...
PCR-RFLP of 12s rRNA and 16s rRNA of Lates calcarifer was carried out. A 415 bp amplified product was obtained from 12s rRNA gene, whereas 700 bp amplified product could be obtained from 16s rRNA gene by PCR. The RFLP of 16s PCR product when digested with Mbo I showed restriction fragments of approx. 275 bp and 200 bp. All the PCR products obtained from different regions showed monomorphism. Cla I was found to be a non-informative restriction enzyme and no restriction fragments could be generated using this enzyme. Alu I restriction digestion of 12s PCR product showed restriction fragments of approximately 250 bp and 75 bp. However, Alu I also generated monomorphism on samples collected from different regions ...

Ferrous slags are inorganic UVCB similar to natural rock. These materials contain trace elements of toxicological or environmental relevance. The accumulation of these elements was tested in field studies. For several elements tested, there was a high scattering of their concentrations in animals and algae, including controls, but it could not be shown that a significant accumulation of these trace elements occurred. The BCF 10 was taken as the worst case for heavy metals in aquatic environments to cover for the influence of slags in comparison to natural rock material Since slags are inorganic UVCB similar to natural rock, there is no need to perform any study on bioaccumulation.

Lestrimelitta limao is a neotropical eusocial bee species found in Brazil and Panama and is part of the Apidae family. It is a species of stingless bees that practices obligate nest robbing. They have never been spotted foraging from flowers, an observation that supports their raiding behavior. Because of their lack of hind corbicula, they must raid to obtain enough protein in their diet in the form of pollen and nectar. Lestrimelitta limao secrete a lemon-scented alarm allomone, from which they receive their name, in order to conduct successful raids. L. limao are hypothesized to produce poisonous honey that is toxic if consumed by humans. Because robber bees are so rare and difficult to observe, there is a limited scope of information available. Lestrimelitta limao is part of the Apidae family, which consists of bumble bees, euglossines, honey bees, and stingless bees. This species is within the tribe Meliponini. L. limao usually visit the nests of the same family, most notably, Trigona. The ...
A honey bee moistens the forelegs with a protruding tongue and brushes the pollen that has collected on head, body and forward appendages to the hind legs. The pollen is transferred to the pollen comb on the hind legs and then combed, pressed, compacted, and transferred to the corbicula on the outside surface of the tibia of the hind legs.[3] A single hair functions as a pin that secures the middle of the pollen load.

The occurrence of Salmonella and Vibrio cholerae in brackishwater ponds was monitored over a 2-year period in one of the major prawn exporting countries in Southeast Asia. The principal production areas were identified and regular samples taken for Salmonella and V. cholerae analysis. Results demonstrated that brackishwater ponds and cultured prawns were inherently contaminated with both bacterial pathogens. Salmonella spp. were present in 16.0% of prawns and 22.1% of mud/water samples from ponds; and V. cholerae present in 1.5% of prawns and 3.1% of mud/water samples. Culturing by intensive methods tended to favour contamination by these pathogens, which is most likely due to the accumulation of waste and increase in the volume of sediments in ponds. Typical environmental factors such as water temperature, pH, and salinity were all favourable for growth of microorganisms. The incidence of the pathogens increased during the wet season and was marginally higher when ponds were located close to ...

4.7.1 Monitoring water parameters. The important water parameters to be monitored are temperature, salinity, acidity, turbidity and ammonia or hydrogen sulfide content. Temperature affects the growth of the fish, as it slows metabolism and growth when it is low, and increases metabolism and growth when it is high. High temperature in brackishwater ponds is also necessary for better growth of natural foods like benthic algae (lab-lab), or good plankton growth in freshwater ponds.. Salinity is important in brackishwater ponds for maintaining good growth of benthic algae without affecting the milkfish, because it can survive and grow at any level of salinity. Acidity also affects both types of pond system in terms of food growth and fish survival. Acidic water can be treated with lime (CaCO3), and the rate depends on the acidity reading of the water. It is better to do the treatment during pond preparation, when soil is treated with the right amount of lime. Turbidity is the measurement of ...

Chlamydodon mnemosyne, a brackish-water ciliate which feeds on cyanobacteria, is capable of sensing the direction of light. Cells are negatively phototactic in the well-fed state and tend to swim towards the light source when mildly starved. Severely starved cells normally fail to show phototactic responses. An autofluorescent substance, which is present in all life cycle stages, occurs in, or immediately beneath, the plasma membrane of this ciliate. It is located in the anterior left side of a cell, in the same region where mildly starved cells accumulate small orange globules that form a structure known as the stigma. The diameter of the whole area where the autofluorescent substance is located appears to be smaller than the stigma; typically, it consists of two rows of blue-green fluorescence, each row subdivided into 5-10 squares. Since the blue-green autofluorescence is excited by both blue (450-490 nm) and near-ultraviolet (340-380 nm) light, it possibly originates from flavin- and/or ...
Ive always wondered if Ancient lakes referred to 1) the lakes (such as Soap Lake) that now occupy depressions that were scoured out by the Missoula floods 12-15 thousand years ago (Pleistocene), or 2) the much more ancient lakes that existed in that area due to the damming of drainages by lava flows of the Columbia River Basalt around 15 million years ago (Miocene). Evidence for the much more ancient basalt-dammed lakes consists of thick deposits of diatomite that crop out (and are mined) along Silica Rd. between I-90 and the Gorge concert venue. The diatomite is composed of the skeletons of gazillions of diatoms that lived (and died, obviously) in the lakes. While the Pleistocene ancient lakes formed by the Missoula floods are an interesting feature of the area, they have no affect on terroir. The deposits of the Miocene ancient lakes, however, do affect terroir as they are a component of the soils in some parts of the proposed AVA. Joan?? ...

I had to think about this for a while. There are several questions.. In keeping livebearers it is common to be told to add salt. Nobody says if there is something specific about sodium chloride, or if the goal is just to raise TDS, which could be an effect on osmolality or conductivity. Some fish are said to do better in brackish water. (scats, monos) Again, is there something special about sodium chloride.. Some snails (nerites) and some shrimp are said to breed only in brackish water. In the case of nerite snails I read that the water SG should be above 1.003. Mine is above that already.. ...
Many viruses restrict host gene expression during infection, presumably to provide a competitive expression advantage to viral transcripts. Not surprisingly, viruses that induce this host shutoff phenotype therefore generally possess mechanisms to selectively spare viral genes. Gammaherpesviruses promote host shutoff by inducing widespread mRNA degradation. Here, we reveal that during infection with MHV68, the majority of viral transcripts of all classes are regulated by RNA degradation.
The industrial conversion of biomass to high-value biofuels and biochemical is mainly restricted by lignocellulose solubilization. Consolidated bio-saccharification (CBS) is considered a promising process for lignocellulose solubilization depending on whole-cell biocatalysts that simultaneously perform effective cellulase production and hydrolysis. However, it usually takes a long time to reach a high saccharification level using the current CBS biocatalyst and process. To promote the saccharification efficiency and reduce the cost, a Clostridium thermocellum recombinant strain ∆pyrF::KBm was constructed as a new CBS biocatalyst in this study. The key CBS factors, including the medium, inoculum size and cultivation, and substrate load, were investigated and optimized. The saccharification process was also stimulated by adding free hemicellulases, suggesting the need to further enhance hemicellulase activity of the whole-cell catalyst. Under the optimal conditions, the CBS process was shortened by 50%

ABSTRACT: The measurement of genetic variability and assessment of population genetic losses are important components of environmental management programs. Twenty-three natural populations of the Mediterranean brackish-water toothcarp Aphanius fasciatus were investigated using different statistical approaches based on genetic data at 13 polymorphic allozyme loci. In general, no differences between values of within-population genetic variability estimates occurred. The Wilcoxon sign-rank test for heterozygosity excess due to a recent bottleneck was conducted on the array of populations. In addition, a qualitative descriptor of allele frequency distribution was used to infer bottlenecks. Only populations from the Orbetello lagoon and La Salina at Elba Island revealed significant heterozygosity excess under both the infinite allele model (IAM) and stepwise mutation model (SMM). A recent dystrophic crisis may account for the genetic loss detected in the population of A. fasciatus from the Orbetello ...

The species is listed on CITES Appendix I and fully protected under Indonesian law (Jahja 1987). Lowland Anoa occur in a number of protected areas (Indonesian Ministry of Forestry 2013, Burton et al. 2005). There are several key protected areas thought to hold significant populations of this species, including Lore Lindu National Park, Bogani Nani-Wartabone National Park, and Tanjung Peropa Nature Reserve on Sulawesi (Indonesian Ministry of Forestry 2013, Burton et al. 2005), as well as Lambusango Wildlife Reserve on Buton Island (Burton 2001). In 2013 the Indonesian Ministry of Forestry published a Strategy and Conservation Action Plan for Anoa 2013-2022. The vision of this plan is a stable population of Anoa in its wild habitat through reduced poaching (hunting) and illegal trade, maintenance of the existing habitat, through active involvement of the stakeholders. A series of high priority sites for in situ conservation of Anoa have been identified: 11 in mainland Sulawesi, and two in Buton ...
Most of the fish research at SEAFDEC AQD in 1992-1994 was on milkfish. Studies were conducted on year-round spawning through hormonal or environmental manipulation; optimum lipid and protein levels and ration size for captive broodstock; and the influence of spawner age on reproductive performance. The economics of hatchery operations, alone or integrated with broodstock as a commercial enterprise, was assessed. Mass production of larvae was refined with the use of commercial or SEAFDEC-formulated larval diets. Alternative rearing schemes in large tanks and ponds were tried. Hatcheryproduced and wild-caught larvae were compared in terms of growth and production in experimental nursery and grow-out ponds. Supplemental diets for brackishwater grow-out culture were formulated. Studies on broodstock management of grouper Epinephelus spp. included lipid enrichment of the diet and hormonal induction of sex inversion. Seed production techniques were developed but survival rates were low. Grouper ...

The goal of this thesis is to examine the distribution and diagenesis of carbohydrates in aquatic environments. The following questions are studied: what is the carbohydrate composition of sediment in different environments (e.g., deep-sea oxic; shallow-sea oxic; deep-sea anoxic; fresh-water anoxic; brackish-water anoxic, etc.)? How does the environment at the sediment-water interface affect the composition of the carbohydrate input? How do sedimentary carbohydrates compare to plankton carbohydrates? How do metal-carbohydrate interactions and biological degradation affect the diagenesis of carbohydrates in recent sediments? Can fossil carbohydrates be used as a means to elucidate paleo-environments? In order to investigate these questions in a quantitative manner, a liquid chromatographic sugar analyzer sensitive to 10-10 moles was constructed. Various extraction techniques, involving acid hydrolysis and EDTA treatment, were thoroughly examined to determine lability of sugars, sources of ...

The snails maintained in the aquarium generally feed on vegetable material. The ramshorn and pond snails and the nerites are particularly good at grazing algae and will also consume (mainly dead) plant material. Apple snails feed on living plant tissue and hence often destroy aquatic plants. Mystery and trumpet snails feed mainly detritus, i.e. waste material of both plant and animal origin. All the species listed can readily be fed on food tablets and flake intended for ornamental fishes, Apple snails should be given additional meals of lettuce leaves (not sprayed with pesticides!) and the like. Whelks are predators that feel mainly on other snails, but in the absence of the latter will also take granules and frozen foods.. Mussels require micro-organisms, above all algae, as food. The best solution is to feed them "green water", which can be created by adding a few drops of complete pot-plant fertiliser to a clear glass jar of mains water and leaving it so stand in full sunlight.
