mirex residues in wildlife and soils, hawaiian pineapple-growing areas--1972-74.a monitoring program was conducted in the pineapple-growing areas of hawaii from 1972 to 1974 to survey mirex residues in sediments, soils, and aquatic and terrestrial wildlife. residues in pineapple field soils ranged from 3 to 18 ppb 9 months after mirex had been applied. no residues were found in the sediments. only 8 fish of 110 aquatic animals sampled contained mirex; these levels were low and ranged from 3 to 7 ppb. mirex residues in birds ranged from undetectable to 10 ppm; residues in ro ...19751221351

evidence for the extinction of plague in hawaii.plague (infection by yersinia pestis) was present in hawaii for the period 1899-1957 and caused at least 370 fatalities. the first infections came from immigrant commensal rats, probably rattus rattus and rattus norvegicus, on ships from the orient. both species were already established in hawaii and became the widespread local carriers of plague, supplemented by rattus exulans which had colonized the islands in ancient polynesian times. the flea xenopsylla vexabilis arrived with r. exulans, and ...19846364800
stomach nematodes (mastophorus muris) in rats (rattus rattus) are associated with coconut (cocos nucifera) habitat at palmyra rats ( rattus rattus ) and their stomach nematodes (mastophorus muris) were historically introduced to islets at palmyra atoll in the central pacific line islands. to investigate patterns of parasitism, we trapped rats and quantified nematodes on 13 islets of various sizes and habitat types. most rats were parasitized (59%) with an average of 12 worms per infected rat. islet size did not greatly influence parasite population biology. nematodes also did not appear to affect rat condition (w ...201019799487
