| 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 |
| a test of positive association for detecting heterogeneity in capture for capture-recapture data. | the cormack-jolly-seber (cjs) model assumes that all marked animals have equal recapture probabilities at each sampling occasion, but heterogeneity in capture often occurs and should be taken into account to avoid biases in parameter estimates. although diagnostic tests are generally used to detect trap-dependence or transience and assess the overall fit of the model, heterogeneity in capture is not routinely tested for. in order to detect and identify this phenomenon in a cjs framework, we prop ... | 2018 | 31983870 |
| halogenated organic compounds in the eggs of aquatic birds from the gulf of gdansk and wloclawek dam (poland). | diet is the major route of exposure to environmental contaminants in biota and, after penetration into an organism, xenobiotics continue to accumulate in the body. in birds the egg-laying process acts as a transfer mechanism for the accumulated pollutants and results in the burdening of the next generation at an early stage of development. this transfer has a strong influence on developmental disorders and even breeding success. with this in mind polybrominated diphenyl ethers (pbde), polychlori ... | 2019 | 31382198 |
| multigene phylogeny and dna barcoding indicate that the sandwich tern complex (thalasseus sandvicensis, laridae, sternini) comprises two species. | | 2009 | 19348954 |
| bioaccumulation of lead and cadmium in the royal tern and sandwich tern. | lead and cadmium concentrations were measured in eggs and tissues of downy young, prefledgling, and adult royal and sandwich terns collected from galveston bay, texas. these species do not differ significantly in the amount of heavy metals they accumulate; however, they differed from other species of the same trophic level from galveston bay in degree and pattern of temporal accumulations of these metals. lead levels were lower in terns, but cadmium levels in adult terns were higher than those o ... | 1982 | 7073322 |
| variation in population synchrony in a multi-species seabird community: response to changes in predator abundance. | ecologically similar sympatric species, subject to typical environmental conditions, may be expected to exhibit synchronous temporal fluctuations in demographic parameters, while populations of dissimilar species might be expected to show less synchrony. previous studies have tested for synchrony in different populations of single species, and those including data from more than one species have compared fluctuations in only one demographic parameter. we tested for synchrony in inter-annual chan ... | 2015 | 26115174 |
| effects of no. 2 fuel oil on hatchability of marine and estuarine bird eggs. | eggs of louisiana herons, sandwich terns, and laughing gulls were oiled with either 0, 5, or 20 microliter of no. 2 fuel oil in the field and in the laboratory. after 5 days of natural incubation, field-oiled and control eggs were opened and embryonic mortality was determined. no. 2 fuel oil produced 61% mortality in louisiana heron eggs, 56% in sandwich tern eggs, and 83% in laughing gull eggs. hatching success of artificially incubated, oiled eggs appeared to be lower than in control eggs. how ... | 1979 | 444711 |
| trophic ecology drives contaminant concentrations within a tropical seabird community. | to support environmental management programs, there is an urgent need to know about the presence and understand the dynamics of major contaminants in seabird communities of key marine ecosystems. in this study, we investigated the concentrations and trophodynamics of trace elements in six seabird species and persistent organic pollutants (pops) in three seabird species breeding on grand connétable island (french guiana), an area where the increase in human population and mining activities has ra ... | 2017 | 28460236 |
| keep the chicks moving: how sandwich terns can minimize kleptoparasitism by black-headed gulls. | sandwich terns, sterna sandvicensis, often nest in association with black-headed gulls, larus ridibundus. the gulls provide protection against predators, but can also adversely affect the terns' reproductive success through predation and piracy of fish. to test whether leading the chicks away from the nest site is an evasive strategy used by the parents to reduce the incidence of robbery by the gulls, we kept one group of sandwich tern chicks at their original breeding site, while, with a wire-n ... | 1999 | 10328801 |
| a new species of plutarchusia oudemans 1904, with a key to the species (analgoidea: syringobiidae). | plutarchusia brachytarsa sp. n. is described from thalasseus sandvicensis (laridae), yucatan. p. pseudochelopus dubinin 1956, and p. longitarsa (mégnin and trouessart 1884) are reported for the first time from the new world. a key to the genus is provided. | 1977 | 845724 |
| [molecular virological monitoring of newcastle disease virus strains (paramyxoviridae, avulavirus) in the populations of wild birds in the volga estuary (the 2001 data)]. | the paper analyzes the results of isolation of newcastle disease virus (ndv) strains from 336 swaps of 31 wild bird species collected in the 2001 summer in the volga estuary (astrakhan region). twenty-seven ndv strains were isolated from little terns (sterna albifrons) (n=11; infection rate, 24.4%), great cormorants (phalacrocorax carbo) (n=6; 11.1%), coots (fulica atra) (n=8; 6.5%), sandwich terns (sterna sandvicensis) (n=1; 100%), and common redshanks (tringa totanus) (n=1; 50.0%). four strain ... | 2006 | 17087063 |
| estimating age-dependent survival from age-aggregated ringing data-extending the use of historical records. | bird ring-recovery data have been widely used to estimate demographic parameters such as survival probabilities since the mid-20th century. however, while the total number of birds ringed each year is usually known, historical information on age at ringing is often not available. a standard ring-recovery model, for which information on age at ringing is required, cannot be used when historical data are incomplete. we develop a new model to estimate age-dependent survival probabilities from such ... | 2019 | 30766667 |
| host-parasite relationship between colonial terns and bacteria is modified by a mutualism with a plant with antibacterial defenses. | predator-prey and host-parasite interactions and mutualisms are common and may have profound effects on ecosystems. here we analyze the parasitic and mutualistic associations between three groups of organisms: the plant artemisia maritima, bacteria, and a colonial seabird (the sandwich tern sterna sandvicensis) that breeds in dense colonies covered in feces produced by both adults and chicks. a disproportionately large fraction of colonies of the sandwich tern in denmark were located in patches ... | 2013 | 23404068 |
