Populations of cormorants and gulls have remained stable in recent years, but skimmer numbers may have declined. Cormorants produced 1.9 to 2.8 young per pair in nests that remained active throughout the season. Gull and skimmer reproduction was seriously limited by storms and predation. DDE and polychlorinated biphenyl (PCB) residues in carcasses and eggs generally were below levels associated with chronic poisoning and reproductive problems in most species of birdsASW,Galveston BayBirdsbreeding successchlorinated hydrocarbonscontaminantsD 04803 Pollution effectsEggsGalveston BayGullsH SE1.21 WILDLIFELarus atricillaLaughing gulllevelsNestingO 4020 POLLUTION - ORGANISMSorganochlorineP 1000 MARINE POLLUTIONP 6000 TOXICOLOGY AND HEALTHPCBpesticidesPhalacrocorax olivaceusPoisoningpollution effectspopulation declinepopulation dynamicsPopulationsPredationQ1 01504 Effects on organismsReproductionRhynchops nigersexual reproductionstormsTexasUSAUSA,Texas,Galveston BayX 24136 Environmental impactJournal
