Dominance Hierarchies in Marine Invertebrates

The Biological Bulletin, 2021
AbstractDominance hierarchies have been well studied in myriad terrestrial animals, but surprisingly little is known about hierarchies in marine invertebrates; examples are limited to a few species of decapod crustaceans and cephalopods. Is the marine environment less conducive to the establishment of dominance hierarchy structures, or does this just ...

Glycolipids of marine invertebrates

Comparative Biochemistry and Physiology, 1970
Abstract 1. 1. Contents of monosaccharides in the lipid extracts of fifty species of marine invetebrates were determined. 2. 2. Glycolipids were found in the invertebrates of all phyla; Spongia and Echinodermata have the highest and Coeleterrata and Arthropoda have the lowest glycolipid contents. 3. 3.

Endogenous opioids in marine invertebrates

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1985
A study of the presence of opioids in invertebrates was carried out on 11 species of marine organisms, ranging from sponges to tunicates. Delipidized acid-acetone extracts from whole organisms or dissected organs were assayed by receptor binding assays and radioimmuno assays. The extracts from all species tested were found to contain substances capable

Methanotrophic symbioses in marine invertebrates

Environmental Microbiology Reports, 2009
Summary Symbioses 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.

Local Adaptation in Marine Invertebrates

Annual Review of Marine Science, 2011
Local 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 ...

Marine envenomations part 2: Invertebrates

The Journal of Emergency Medicine, 1992
As more people travel to the oceans for sport diving and other marine-related activities, the incidence of marine envenomations has risen. This article is designed to give the emergency medicine physician an overview of varying marine envenomations, their clinical presentation, and recommended treatment.

Antimycobacterial Metabolites from Marine Invertebrates

Archiv der Pharmazie, 2016
Marine organisms play an important role in natural product‐based drug research due to accumulation of structurally unique and bioactive metabolites. The exploration of marine‐derived compounds may significantly extend the scientific knowledge of potential scaffolds for antibiotic drug discovery.

Opine Dehydrogenases in Marine Invertebrates

Biochemical Genetics, 2013
It 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, 2003
AbstractIn 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.
