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 ...19761256912
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 ...19761267025
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 ...19761259030
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 ...19751128176
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 ...19751202414

identification of a xylose-containing cerebroside in the salt gland of the herring gull.a pentose-containing cerebroside has been identified in the salt gland of the herring gull, using mass spectrometry of acetyl and trimethylsilyl derivatives. a detailed interpretation of the spectra allowed a conclusion concerning the major long-chain base (the c(20) homolog of sphingosine) and the major fatty acids (c(22)-c(25) 2-hydroxy fatty acids), using reference spectra of synthetic galactosylceramides. a six-membered glycose ring (aldopyranose) was demonstrated by mass spectrometry of the ...19724335795

some observations on the circulation of influenzaviruses in domestic and wild birds.four viruses isolated from poultry in the ussr and poland were identified as influenza a strains. one strain was closely related to fowl plague virus, the second showed an antigenic relationship to a/chicken/scotland/59 (hav5n1), and two others were antigenically related to a/duck/ukraine/1/63 (hav7neq2) and a/duck/england/56 (hav3nav1). antibodies to different strains of influenzavirus were detected in sera collected from poultry and from wild birds in the northern area of the ussr. more of the ...19724541001

chlorinated hydrocarbons and eggshell changes in raptorial and fish-eating birds.catastrophic declines of three raptorial species in the united states have been accompanied by decreases in eggshell thickness that began in 1947, have amounted to 19 percent or more, and were identical to phenomena reported in britain. in 1967, shell thickness in herring gull eggs from five states decreased with increases in chlorinated hydrocarbon residues.19684877438

emesis in birds.comparative studies of emesis in the herring gull, pigeon, chicken, and cowbird were conducted, using orally administered copper sulfate and intravenously administered copper sulfate, hydergine, apomorphine, and lanatoside c. a response to every emetic was elicited from some birds. however, the individual and species differences among the birds were as great as those among mammals. further, the response of the avian species studied did not indicate that any of them could be used to predict how a ...196622413208
