The synthesis of (-)-complanine, an inflammatory substance of Eurythoe complanata, was accomplished by a "chiral synthon" approach. The absolute configuration of this molecule was determined to be R.
We computationally study the transport of active, self-propelled particles suspended in a two-dimensional chaotic flow. The pointlike, spherical particles have their own intrinsic swimming velocity, which modifies the dynamical system so that the particles can break the transport barriers present in the carrier flow. Surprisingly, we find that swimming does not necessarily lead to enhanced part...
s of, and/or summary reports of scientific meetings; and simple bibliographies. Issues receive internal scientific review and most issues receive copy editing. Resource Survey Report (formerly Fishermen’s Report) -This information report is a regularly-issued, quick-turnaround report on the distribution and relative abundance of selected living marine resources as derived from each of the NEFSC...
Background: Manta rays (Mobulidae), Mobula birostris and Mobula alfredi, are widely distributed in tropical and temperate waters. Still, little is known about their movements and their ecological interactions (e.g. behavior and diet). In Peru, M. birostris has only been reported along the northern shore within the Tropical East Pacific Marine Province. No official reports exist from central or ...
Pesticides usage in agricultural fields to control pests is extremely toxic to non target organisms like fish and affect fish health through impairment of metabolism, sometimes leading to mortality. Present study is a review of potential adverse effects of pesticides and pollutants in fish. Furthermore, the data generated could be useful in the environmental risk assessment of freshwater and ma...
1. introduction seas and oceans comprise over 70 percent of the planet earth always taken into attention in the history. however, the most important official and legal actions to regularize a number of claims made by coastal countries regarding the demand of the territorial and marine control and exclusive ownership date the 20th century. the first conference on marine international law was hel...
