Ubiquinones of marine invertebrates
Chemistry of Natural Compounds, 1981The quantitative and qualitative compositions of the ubiquinones of 28 species of marine invertebrates representing five main types have been studied. The amount of ubiquinones did not exceed 5 µg per 1 g dry weight. For all species the main component is Q10, except for ascidians, which produce only Q9.

Methanotrophic symbioses in marine invertebrates
Environmental Microbiology Reports, 2009SummarySymbioses between marine animals and aerobic methane‐oxidizing bacteria are found at hydrothermal vents and cold seeps in the deep sea where reduced, methane‐rich fluids mix with the surrounding oxidized seawater. These habitats are ‘oases’ in the otherwise nutrient‐poor deep sea, where entire ecosystems are fueled by microbial chemosynthesis ...

Alginases of marine invertebrates
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971Abstract 1. 1. The alginase activity was determined in the digestive system of over forty species of marine invertebrates from various phyla. 2. 2. The activity was measured by the increase of reducing sugars in incubated mixtures; by absorption increase at 235 nm; and by the viscosity decrease of the alginate solution. 3. 3.

Endocrine mechanisms in marine invertebrates
Life Sciences, 1974Abstract The objective of this minireview is to summarize the recent advances made in the area of marine invertebrate endocrinology, with special emphasis on the literature published in 1972 and 1973. Most of the pertinent publications in these two years have dealt with crustaceans.

Local Adaptation in Marine Invertebrates
Annual Review of Marine Science, 2011Local adaptation in the sea was regarded historically as a rare phenomenon that was limited to a handful of species with exceptionally low dispersal potential. However, a growing body of experimental studies indicates that adaptive differentiation occurs in numerous marine invertebrates in response to selection imposed by strong gradients (and more ...

Taurine in Marine Invertebrates
1971Publisher Summary Taurine is not only an oxidative end product but also a key intermediate of sulfur metabolism. In marine invertebrates it appears to have three organic functions. It can be shown that specimens of Mya subjected to low salinities greatly increase the rate of loss of ammonia from their bodies. However, no comparable increase occurs in

Development of Marine Invertebrates
2020Marine invertebrates are used in developmental, cell, and evolutionary biology, and some critical biological phenomena have been found using these organisms. For example, one of the most important cell-cycle regulator proteins, cyclin, was found in a sea urchin (Evans et al., Cell 33:389–396, 1983); the cell-fate determinant, macho-1, was first ...

Opine Dehydrogenases in Marine Invertebrates
Biochemical Genetics, 2013It is well known today that opine production anaerobic pathways are analogs to the classical glycolytic pathway (lactate production pathway). These pathways, catalyzed by a group of enzymes called opine dehydrogenases (OpDHs), ensure continuous flux of glycolysis and a constant supply of ATP by maintaining the NADH/NAD(+) ratio during exercise and ...

Polyspermy prevention in marine invertebrates
Microscopy Research and Technique, 2003AbstractIn marine invertebrates, as in most other organisms, normal development requires that only one sperm nucleus joins with the egg nucleus at fertilization. The principal mechanisms employed are (1) prevention of sperm‐egg plasma membrane fusion and (2) modifications of the egg extracellular coat to prevent sperm binding and/or penetration.

Pigments of Marine Invertebrates
1979Publisher Summary Marine plants and animals are often very brilliantly colored, especially those from tropical waters. Even in temperate climates many animals of the sea-shore, when viewed in quantity as in a rock pool association, present a fine sight, but in warmer waters, corals and their attendant fauna and flora provide a pageant of great beauty.
