| ingestion of crude oil: sublethal effects in herring gull chicks. | a single small oral dose of kuwait or south louisiana crude oil caused cessation of growth, osmoregulatory impairment, and hypertrophy of hepatic, adrenal, and nasal gland tissue in herring gull chicks living in a simulated marine environment. these findings suggest that ingesting crude oil causes multiple sublethal effects that might impair a bird's ability to survive at sea. | 1978 | 145655 |
| behavioral thermoregulation: orientation toward the sun in herring gulls. | orientation toward the sun combined with postural changes minimized the net radiation gain on the adult herring gull during the breeding season. the decrease in absorbed solar radiation was due to reduced surface area exposed to direct sunlight and to reduced absorptivity since, when the bird orients toward the sun, the angle of incidence is such that only the white surfaces receive direct sunlight. at low wind velocities (0 to 0.6 meter per second) and ambient temperatures above the lower criti ... | 1978 | 635577 |
| [comments on the exchangeability of herring-gull chicks (larus argentatus) after the 1st week of life]. | in the biville chalk cliff area the herring gulls nest both in slope and ground colonies and on cliff ledges. like the kittiwake (cullen 1957), the cliff-nesting pairs still accept other chicks after the 1st week of life. gulls in slope and ground colonies, however, attack those chicks older than 4 days in close proximity to their nests (tinbergen 1936). | 1978 | 696024 |
| [life-cycle of renicola lari j. timon-david, 1933 (trematoda, renicolidae) (author's transl)]. | this paper deals with life-cycle of renicola lari j. timon-david, 1933. description and illustration are given. sporocyst development occurs inside the visceral mass of cerithium mediterraneum and c. rupestre (mollusca prosobranchia). cercariae are planktonic; they are swallowed up by the second intermediate host, atherina hepsetus and a. boyeri (teleostean fishes). cercariae perforate intestine wall. metacercariae are encysted in liver. adult flukes have been recovered in kidneys of uninfected ... | 2006 | 754615 |
| effects of telemetry transmitter weight on breeding success in herring gulls. | dummy ratio-tracking transmitters weighing 10, 30 and 50 g were attached to randomly chosen pairs of breeding herring gulls (larus argentatus). breeding success was measured as a function of eggs hatched and chicks fledged. fewer clutches survived if patients were subjected to more severe treatments (p less than 0.02). component effects (catching pairs of gulls or increased transmitter weight) were not singularly significant in decreasing clutch success. | 1978 | 754822 |

| stereoscan studies of cercariae, metacercariae, and adults of cryptocotyle lingua (creplin 1825) fischoeder 1903 (trematoda: heterophyidae). | the cercaria of cryptocotyle lingua has simple pointed spines all over the body. four pointed modified spines occur dorsally in the mouth, and similar spines surround the openings of the penetration glands. the modified spines are shed shortly after penetration and encystment in the fish host. less than a week after encystment, cytoplasmic folds develop all over the tegument. after about 4 weeks the cytoplasmic folds have disappeared and the spines are now flattened and serrated. the external su ... | 1977 | 915613 |
| the ornithodoros (alectorobius) capensis group (acarina: ixodoidea: argasidae) of the palearctic and oriental regions. o. (a.) maritimus: identity, marine bird hosts, virus infections, and distribution in western europe and northwestern africa. | in 1967, vermeil and marguet described ornithodoros coniceps maritimus from larvae reared from larvae taken from marine birds on dumet island (atlantic ocean), basse bretagne, france. we collected o. (a.) coniceps canestrini, 1890, from the type locality (venice, italy) and determined that the taxons coniceps and maritimus each require full species status. we selected a lectotype and paralectotypes for the taxon maritimus from the original dumet island material. the larva of maritimus is redescr ... | 1976 | 978368 |
| [the life cycle of maritrema misenensis (a. palombi, 1940), n. comb. (trematoda: microphallidae, travassos, 1920) from french mediterranean coast (author's transl)]. | the life cycle of maritrema misenensis (a. palombi, 1940) n. comb. is described with illustrations. the sporocysts parasite the digestive gland of the prosobranch snail cerithium mediterraneum. the cercariae are the same as cercaria misenensis, a. palombi, 1940 described from italian coast. the adults have been obtained by artificial infestations of larus argentatus michaellis. their morphological features are same as those of the caribbean species maritrema patulus w.h. coil, 1955. when the lif ... | 1976 | 984671 |
| fatty acid and aldehyde composition of major phospholipids in salt gland of marine birds and spiny dogfish. | the lipophilic components of choline phosphoglycerides and ethanolamine phosphoglycerides obtained from the salt gland of herring gull and eider duck and from the rectal gland of spiny dogfish were investigated by means of thin-layer chromatography, gas chromatography, and gas chromatography-mass spectrometry. all phospholipids analyzed were shown to contain small amounts of plasmalogens, and mainly c16, c18, and c18:1 aldehyde was detected. the fatty acids were composed of saturated, unsaturate ... | 1975 | 1128176 |
| [the systematic position of mites of the genus larinyssus strandtmann (gamasoidea, rhinonyssidae), parasitizing gulls]. | a study was carried out of the variability of mited colledted from 6 species of birds as follows: larus argentatus pontopp., l. minutus pall., gelochelidon nilotica gm., chlidonias leucoptera (temm.), ch. nigra (l.) and sterna hirundo l. structural peculiarities characteristic of the parasites of the above species have been revealed. the mites from st. hirundo were isolated into a distinct species, larinyssus substerna sp. n., which is most close to l. sterna fain, 1972. the new species differs ... | 2007 | 1143929 |
| an experimental investigation of a direct life-cycle in reighardia sternae (diesing, 1864), a pentastomid parasite of the herring gull (larus argentatus). | a direct life-cycle in reighardia sternae, a cephalobaenid pentastomid of gulls was investigated: the work was prompted by a report of eggs and larvae recovered from the stomach and intestine of a naturally infected gull. infective pentastomid eggs were obtained by surgically transplanting maturing female reighardia, taken from freshly shot wild gulls, into captive recipients. faecal material from birds thus artificially infected was collected daily and examined for eggs. eggs were force fed to ... | 1975 | 1202414 |
| some observations on egg production and autoreinfection of reighardia sternae (diesing, 1864), a pentastomid parasite of the herring gull. | egg production by reighardia sternae, implanted at various stages of maturity into the interclavicular air sacs of captive gulls, is described. females produce only 2900 eggs per lifetime over a short patent period of 1-3 days. the problem of a direct life-cycle in relation to this unusually low fecundity is discussed, and speculation is advanced concerning a possible parasitic behavioural trait which could facilitate direct transmission. the hazards of the latter are also offset by auto-reinfec ... | 1976 | 1256912 |
| intracellular concentrations of the salt gland of the herring gull larus argentatus. | attempts were made to measure intra- and extracellular concentrations in secreting and inactive salt gland tissue of the herring gull. 14c-labeled polyethylene glycol (mol wt 4,000) was used as a marker for extracellular fluid. fluid separated by centrifugation at 36,000 g appeared by three independent criteria to represent primarily extracellular fluid. it could not, however, be fully ascertained if this fluid was mixed with a small amount of intracellular fluid. therefore, intracellular concen ... | 1976 | 1259030 |
| heat loss from feet of herring gulls at rest and during flight. | the role of the feet of herring gulls (larus argentatus) in heat dissipation was estimated during rest and wind-tunnel flight. we determined the blood flow to the feet and the arteriovenous temperature difference and thus estimated heat loss from the feet. determinations of oxygen consumption and respiratory water loss at rest gave a heat production of about 8 w; 37-56% of this heat was lost from the feet (air temp = 10-35 degrees c). during flight heat production was estimated to be about 57 w ... | 1976 | 1267025 |
| heavy metal and metallothionein concentrations in atlantic canadian seabirds. | seabird tissues, collected during the 1988 breeding season from colonies on the atlantic coast of canada, were analyzed for toxic metals--cd, hg and pb--and 18 other trace elements. metallothionein (mt) was measured in kidney, and kidneys and livers underwent histopathological examination. levels of most essential trace elements appear to be closely regulated in seabird tissues; values were in good agreement with those previously reported in the published literature. liver-se concentrations in l ... | 1992 | 1554255 |
| comparison of lead levels in bone, feathers, and liver of herring gull chicks (larus argentatus). | bone, feathers, and liver were analyzed for lead in herring gull chicks (larus argentatus) of two different ages. the highest levels were found in the bone, evidence of chronic exposure. no differences were found within the bones. differences occurred between different bones, with the ribs having twice the amount of lead than any other bone. these studies indicate that type of bone affects lead levels; thus researchers should clearly state which parts of which bones are examined. it is also sugg ... | 1992 | 1574517 |
| a modelling strategy for recovery data from birds ringed as nestlings. | in this paper we propose a strategy for analysing recovery data from birds ringed as nestlings. the approach advocated starts with a global model, involving calendar year dependence of both reporting and first-year survival rates, and age-dependence of survival rates for older birds. likelihood ratio tests are then used to choose between a range of submodels. the strategy is illustrated through application to three data sets, on mallards, herring gulls, and blue-winged teal. the effect of age-de ... | 1992 | 1581486 |
| occurrence of campylobacter spp. in young gulls, duration of campylobacter infection and reinfection by contact. | two groups of three week old herring gulls (larus argentatus) were held to observe the carrier state with campylobacter. all 27 birds of group i excreted campylobacter jejuni biotype iii when they were caught from their colony. four weeks later all but one were negative, indicating that the carrier state lasts until about the seventh week of life, with self-elimination if infection with another campylobacter species is prevented by housing in a closed environment as in this study. only one bird ... | 1992 | 1621473 |
| great lakes embryo mortality, edema, and deformities syndrome (glemeds) in colonial fish-eating birds: similarity to chick-edema disease. | several species of colonial fish-eating birds nesting in the great lakes basin, including herring gulls, common terns and double-crested cormorants, have exhibited chronic impairment of reproduction. in addition to eggshell thinning caused by high levels of ddt and metabolites, the reproductive impairment is characterized by high embryonic and chick mortality, edema, growth retardation, and deformities, hence the name great lakes embryo mortality, edema, and deformities syndrome (glemeds). the h ... | 1991 | 1875430 |
| productivity, diet, and environmental contaminants in bald eagles nesting near the wisconsin shoreline of lake superior. | bald eagles (haliaeetus leucocephalus) nesting in the apostle islands national lakeshore and along the wisconsin shoreline of lake superior produced an average of 0.8 young/occupied nest and had an average nest success of 57% during 1983-1988, compared to 1.3 young/occupied nest and 77% nest success in inland wisconsin. contaminant levels in nestling bald eagle carcasses collected from nests near lake superior were higher than those collected inland, suggesting local contamination. prey remains ... | 1991 | 1996910 |
| [the occurrence of campylobacter spp. and salmonella spp. in gulls in northern germany]. | out of a total of 207 gulls--20 black headed gulls, 185 herring gulls and 2 common gulls--128 (62%) and 23 (11%) birds, respectively, were infected with campylobacter spp. (c.) and salmonella spp. c. jejuni was predominant in gulls less than two years old (89%) and c. coli in older birds (75%). furthermore, the infection rate with campylobacters was depending on the habitats of the birds. the rate for c. jejuni and c. coli, respectively, was in gulls from regional garbage dumps 78% and 4%, from ... | 1991 | 2065612 |
| geographical distribution of contaminants and productivity measures of herring gulls in the great lakes: lake erie and connecting channels 1978/79. | the distribution and size of colonies, residue levels of dde, ddt, hcb, dieldrin, mirex and pcbs in eggs, productivity and eggshell thickness were determined for herring gulls at 14 sites in lake erie and connecting channels. the centre of distribution for breeding herring gulls was the western basin where approximately 90% of the 6200 nests in the study area were located. seven of 22 colonies showed an average annual population increase of 48.3%. most of the increase in breeding herring gulls o ... | 1990 | 2108495 |
| the laboratory maintenance of diphyllobothrium dendriticum (nitzsch, 1824). | a protocol for the routine laboratory maintenance of the life-cycle of diphyllobothrium dendriticum, using herring gulls (larus argentatus), cyclops abyssorum and rainbow trout oncorhynchus mykiss ( = salmo gairdneri) as the definitive, first and second intermediate hosts respectively, is described. | 1990 | 2235071 |
| tissue levels of lead in experimentally exposed herring gull (larus argentatus) chicks. | two-day-old herring gull (larus argentatus) chicks were injected with either 0.1 or 0.2 mg lead/g body mass and were sacrificed at 45 d of age. control birds were injected with sterile water. we examined lead and cadmium levels in blood, kidney, liver, muscle, salt glands, breast feathers, and bone. in control birds lead levels were highest in bone, feathers, salt gland, and kidney, and lowest in blood, muscle, and brain. in experimental birds lead levels were highest in bone, liver, kidney, and ... | 1990 | 2299695 |
| behavioral effects of early postnatal lead exposure in herring gull (larus argentatus) chicks. | lead exposure early in life affects behavioral and intellectual development in humans. in this paper, i use the herring gull, larus argentatus, as an animal model to examine effects of lead exposure on early development. like humans, birds rely mainly on visual and vocal, rather than olfactory, modes of communication. each of 24 one-day-old herring gull chicks was randomly assigned to one of three treatment groups to receive a lead nitrate solution at a concentration of 0.0, 0.1 and 0.2 mg/g. th ... | 1990 | 2315373 |
| morphological lesions in red blood cells from herring gulls and atlantic puffins ingesting prudhoe bay crude oil. | red blood cells from nestling herring gulls and atlantic puffins that had ingested 10 ml or more of a prudhoe bay crude oil/kg body weight/day for four to five days were examined by light and electron microscopy. in stained smears, red blood cells from oil-dosed birds were characterized by anisocytosis, poikilocytosis, reticulocytosis, and heinz body formation. in transmission electron micrographs, affected cells had intracytoplasmic and intranuclear heinz bodies, a variety of abnormal cytoplasm ... | 1985 | 2412333 |
| an assessment of pollutants in eggs of audouin's gull (larus audouinii), a rare species of the mediterranean sea. | audouin's gull (larus audouinii) is a very rare species endemic to the mediterranean basin. a sub-population of an estimated 130 pairs is breeding in the tuscan archipelago, an area heavily polluted by mercury and chlorinated hydrocarbons. here we present the data from 5 years spent monitoring the contaminant levels in the eggs of this species. mercury, selenium, polychlorobiphenyls (pcbs) and dde concentrations are two to five times higher than in similar species, such as the yellow-legged herr ... | 1989 | 2497516 |
| [circulation of the influenza a virus of h13 serosubtype among seagulls in the northern caspian (1979-1985)]. | the results of seven-year ecologo-virological studies (1979-1985) of laridae colonies on the island zhemchuzhnyi, northern kaspian sea, showed annual isolation of influenza a viruses. altogether, 95 hemagglutinating agent have been isolated. strains with 4 different combinations of surface antigens were identified: h5n2, h13n2, h13n3, h13n6. the possibility of transovarial transmission is confirmed by the fact of isolation of an influenza virus strain a/black-headed herring gull/astrakhan/458/85 ... | 1989 | 2531497 |
| erve virus, a probable member of bunyaviridae family isolated from shrews (crocidura russula) in france. | an apparently new agent, provisionally named erve virus, was isolated in 1982 from tissues of three white toothed shrews, crocidura russula, trapped near saulges village in western france. results of virological and ultrastructural studies suggest that this virus belongs to the bunyaviridae family and is a bunyavirus-like agent. serosurveys indicate that erve virus had apparently a large geographical distribution in france and infects rodents, insectivores, wild boars (sus scrofa), red deer (cer ... | 1989 | 2570514 |
| [hematologic and hematochemical characteristics of the herring gull (larus argentatus) and the buzzard (buteo buteo)]. | some hematological and hematochemical parameters in eight herring gulls (larus argentatus) and in six buzzards (buteo buteo) were checked. the buzzards were fed with ovine meat exclusively, while the herring gulls were fed with fish and ovine meat. considerable differences between the two species were noted, particularly as far as the hematological and lipidic parameters are concerned. these differences are probably related to the aquatic life of the herring gull. | 1989 | 2627341 |

| dynamics of egg production of the cestode diphyllobothrium dendriticum (nitzsch, 1824) (cestoda: pseudophyllidea) and the concept of fecundity in helminths. | the dynamics of egg production of the tapeworm d. dendriticum has been estimated experimentally in nestlings of the herring gull larus argentatus per day and per reproductive period. numbers of eggs in strobilae have been estimated for the maturation period. mean egg production, of one tapeworm per day (10.42 +/- 2.72 mln) is two orders of magnitude as high as the maximal number of eggs in a mature strobila (0.206 +/- 0.007). it is proposed to estimate the coefficient of reproduction intensity a ... | 1989 | 2767550 |
| blood chemistry changes in food-deprived herring gulls. | blood chemistry changes caused by food-stress was measured in fledgling herring gulls (larus argentatus). increases of corticosterone, t3, free fatty acids, glucose, cholesterol and alpha-amino n-butyric acid were observed. significant decreases were found in the concentrations of 14 of the 26 free amino acids studied. | 1985 | 2863080 |
| postsynaptic alpha 1- and alpha 2-adrenoceptors in the vascular system of the herring gull, larus argentatus. | the nature of the vascular alpha-adrenoceptors has been studied in the herring gull, larus argentatus. in the anaesthetized herring gull, both phenylephrine and clonidine elicited dose-dependent increases in arterial blood pressure. the alpha 1-adrenoceptor antagonist prazosin was a better antagonist of phenylephrine than were the alpha 2-adrenoceptor antagonists yohimbine and rauwolscine. yohimbine and rauwolscine were better antagonists of clonidine than was prazosin. the maximum response to p ... | 1986 | 2879594 |
| mixed-function oxidase activity in seabirds and its relationship to oil pollution. | 1. the hepatic activity of epoxide hydrolase, aldrin epoxidase, aminopyrine n-demethylase, 7-ethoxyresorufin o-deethylase, benzo(a)pyrene 3-hydroxylase and udp glucuronyl transferase was determined in adult herring gulls (larus argentatus) at various stages of the breeding season. 2. mfo activity was measured for adult leach's storm-petrels (oceanodroma leucorhoa), guillemot (uria aalge) and atlantic puffins (fratercula arctica). for most assays the values were highest for the puffin. 3. mfo act ... | 1987 | 2890477 |
| the isolation of meaban virus, a new flavivirus from the seabird tick ornithodoros (alectorobius) maritimus in france. | seven strains of a new flavivirus, for which the name of meaban virus is proposed, were isolated from the seabird tick ornithodoros (a.) maritimus collected during 1981 and 1982 in nests of herring gulls (larus argentatus) on islands of south brittany, france. the new virus was compared serologically with 65 other flaviviruses including tyuleniy virus and was found to be most closely related to, but different from saumarez reef virus, an agent previously isolated in australia and tasmania. some ... | 1985 | 2982352 |
| nitrite poisoning in herring gulls (larus argentatus) and ring-billed gulls (larus delawarensis). | landfill disposal of a fertilizer manufacturing waste product was associated with a die-off of gulls in new hanover county, north carolina. an estimated 250 herring and ring-billed gulls were found dead at the site following the initial disposal of this material. chemical analyses revealed that the fertilizer waste contained predominately calcium (12.0 to 22.2%) and nitrite (3.0 to 15.2%). contents of the proventriculi and gizzards of dead gulls also contained calcium (3.0 to 10.9%) and nitrite ... | 1986 | 3016349 |
| sensitivity of embryos from duck, goose, herring gull, and various chicken breeds to 3,3',4,4'-tetrachlorobiphenyl. | yolks in embryonated eggs from duck, goose, herring gull, and various breeds of chicken were injected with 3,3',4,4'-tetrachlorobiphenyl (tcb). hens' eggs were injected after 4 days of incubation and eggs from the other species were injected after 5 days of incubation. all breeds of chicken tested were very sensitive to tcb. at a dose of 20 micrograms/kg egg the death rate in chick embryos ranged from 70 to 100% at the end of the experiment by day 18 of incubation. liver lesions, hydropericardiu ... | 1988 | 3131755 |

| effects of lead on growth in young herring gulls (larus argentatus). | one-day-old herring gulls (larus argentatus) were injected intraperitoneally with lead nitrate solution (0.1 or 0.2 mg pb/g) or sterile saline to examine differences in growth rates. despite the low levels of lead exposure, by d 8 there were significant differences in growth rates as a function of treatment. there were also, by d 8, significant differences in bill length, tarsus length, and wing bone length. except for bill length, these differences persisted for the duration of the study. devel ... | 1988 | 3172274 |
| measurement of growth rates: the effect of sampling time on weight in a seabird. | in most field studies on growth rates of birds, chicks are weighed in the "morning" or whenever it is convenient. i found that weight of laboratory-reared young herring gulls (larus argentatus) varied significantly depending on the time of day it was measured. chicks were always lighter at daybreak before they had eaten. however, mean weight at other times of the day was less variable. these results suggest that it is important to always weigh chicks at the same time each day, and to appreciate ... | 1988 | 3203978 |
| toxicological investigations of pollutant-related effects in great lakes gulls. | reproductive failure of a number of fish-eating birds was observed on the great lakes in the mid-1960s to mid-1970s. the herring gull (larus argentatus) has been used as the primary monitoring species. the low hatching success observed in this species on lake ontario in the mid-1970s was due to loss of eggs and failure of eggs to hatch. egg exchange experiments demonstrated that this was due both to the incubation behavior of adults and to direct embryotoxic effects. decrease of nest attentivene ... | 2012 | 3297661 |
| skull deformity in a herring gull chick (larus argentatus). | a skull deformity resulting in death of a herring gull chick (larus argentatus) is described in detail. the bones of the skull and upper jaw were twisted, asymmetrical and of unusual size or absent. the lower jaw had an almost "spoon-like" external appearance and lacked normal articular surfaces. | 1988 | 3352082 |

| lead, mercury, cadmium and selenium in two species of gull feeding on inland dumps, and in marine areas. | the influence of the foraging area on the intake of trace elements was evaluated in tissues of two species of gull: the black-headed gull (larus ridibundus) and the herring gull (larus argentatus). mercury levels were higher in birds from the coastal environment than in those caught on inland dumps; birds found at one dump site showed high levels of lead. interspecific differences in the levels of mercury and cadmium are discussed. | 1986 | 3810137 |
| renal excretion in gull chicks: effect of parathyroid hormone and calcium loading. | renal clearance experiments were performed on herring gull (larus argentatus) and great black-backed gull chicks (l. marinus) to test the importance of parathyroid hormone (pth), parathyroidectomy (ptx), and calcium loading on excretion patterns of sodium, potassium, calcium, and phosphate. ptx reduced the relative clearance of phosphate to near zero within 2 h. conversely, pth stimulated net secretion of phosphate within 40 min. calcium loading caused a drop in phosphate excretion identical to ... | 1986 | 3942252 |
| a quantitative assessment of thyroid histopathology of herring gulls (larus argentatus) from the great lakes and a hypothesis on the causal role of environmental contaminants. | thyroids from 213 adult herring gulls of both sexes were collected during incubation from nine colonies in the great lakes basin of eastern north america between 1974 and 1983, and from a single colony in the bay of fundy from 1977 to 1982. qualitative and quantitative histological assessment revealed that the majority of the gulls from the great lakes basin suffered from goiter. these thyroids had a greater mass than those from the bay of fundy, and were microfollicular and frequently hyperplas ... | 1986 | 3951063 |
| effects of ingestion of hibernia and prudhoe bay crude oils on hepatic and renal mixed function oxidase in nestling herring gulls (larus argentatus). | oral administration of prudhoe bay crude or hibernia crude to nestling herring gulls increased the hepatic cytochrome p-450 content 4-fold. concomitantly, there was an increase in various mixed-function oxidase and phase ii enzyme activities. 7-ethoxyresorufin o-deethylase was elevated 19-fold, benzo(a)pyrene 3-hydroxylase 6-fold, aniline hydroxylase 3-fold, and aminopyrine n-demethylase and uridine diphosphate glucuronyl transferase 2-fold. there was no change in reduced glutathione s-transfera ... | 1985 | 3967642 |
| long-term preservation of egg and tissue homogenates for determination of organochlorine compounds: freezing versus freeze-drying. | storage of wet egg homogenates at temperatures from -18 degrees to -28 degrees c was more suitable for long-term preservation than freeze-drying. changes in residue levels of heptachlor epoxide, oxychlordane, dieldrin, hexachlorobenzene,p,p'-dde, mirex, and pcbs were not significant over a 3-year period in fresh herring gull egg homogenates stored at -18 degrees to -28 degrees c. compounds with gas chromatographic retention times shorter than hexachlorobenzene vaporized during freeze-drying at a ... | 1985 | 3980402 |
| biochemical and functional disturbances in red blood cells of herring gulls ingesting prudhoe bay crude oil. | heinz body hemolytic anemia developed in herring gull (larus argentatus) nestlings given oral doses of 10 ml of prudhoe bay crude oil per kilogram of body weight per day for 5 days. associated disturbances in red blood cells were increased amounts of reduced glutathione (gsh), peroxidation of membrane lipids, an increase in membrane permeability, and a decrease in the oxygen-carrying capacity of cyanomethemoglobin-convertible hemoglobin. among groups of gulls given different cumulative doses of ... | 1985 | 4049418 |
| hemograms and microscopic lesions of herring gulls during captivity. | herring gulls (larus argentatus) kept in captivity for a maximum of 28 days developed marked heterophilia and nonregenerative anemia. these hematologic findings remained abnormal throughout captivity. concurrently, severe amyloid deposition was seen in vessel walls of the spleen and in other tissues, and vacuolar degeneration of catecholamine-producing cells of the adrenal glands was found in gulls necropsied at various intervals. behavioral signs of stress were seen in the early stages of capti ... | 1985 | 4077622 |
