Canadian fishery closures provide a large-scale test of the impact of gillnet bycatch on seabird populations.
In 1992, the eastern Canadian gillnet fisheries for northern cod and Atlantic salmon were largely closed. These large-scale fishery closures resulted in the removal of tens of thousands of gillnets known to inflict high levels of seabird mortality. We used this unprecedented opportunity to test the effects of gillnet removal on seabird populations. Consistent with predictions, we show that the ...
متن کاملApplication of immobilized microbial cells in biological treatment of contaminated effluent with aromatic compounds: a review article
Background and Objective: Bioremediation of contaminants by living microorganisms is a favorable method for elimination or degradation of pollutants to less harmful substances. In the recent decades, cell immobilization technique has been applied to improve biodegradation efficiency and also overcome to free cells disadvantages. The purpose of this review article is to investigate the applicati...
متن کاملNew Approach for Removal of Total Hardness ( Ca2+, Mg2+ ) from Water Using Commercial Polyacrylic Acid Hydrogel Beads, Study and Application
Adsorption and water treatment of Ca (II) and Mg (II) hardness were investigated via adsorption of metal ions onto commercial polyacrylic acid hydrogel beads as a novel sorbent for metal ions (Ca2+, Mg2+) removal and water treatment. Batch equilibrium technique was carried out under the influence of solution pH, contact time, sorbent dosage, initial metal concentration and...

متن کاملSalt and water stress of ACCase herbicides resistant and susceptible populations of rigid ryegrass (Lolium rigidum)
Laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant Lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. Factors evaluated were Lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 dS cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). The maximum germination in salinity stres...
