Seabirds and the Circulation of Lyme Borreliosis Bacteria in the North Pacific

Vector-Borne and Zoonotic Diseases (2011)

Elisa Lobato Jessica Pearce‐Duvet Vincent Staszewski Elena Gómez‐Díaz Jacob González‐Solís

Seabirds act as natural reservoirs to Lyme borreliosis spirochetes and may play a significant role in the global circulation of these pathogens. While Borrelia burgdorferi sensu lato (Bbsl) has been shown to occur in ticks collected from certain locations in the North Pacific, little is known about interspecific differences in exposure within the seabird communities of this region. We examined the prevalence of anti-Bbsl antibodies in 805 individuals of nine seabird species breeding across the North Pacific. Seroprevalence varied strongly among species and locations. Murres (Uria spp.) showed the highest antibody prevalence and may play a major role in facilitating Bbsl circulation at a worldwide scale. Other species showed little or no signs of exposure, despite being present in multispecific colonies with seropositive birds. Complex dynamics may be operating in this wide scale, natural host-parasite system, possibly mediated by the host immune system and host specialization of the tick vector.

Exposure of black‐legged kittiwakes to Lyme disease spirochetes: dynamics of the immune status of adult hosts and effects on their survival

Journal of Animal Ecology (2012)

Thierry Chambert Vincent Staszewski Elisa Lobato Rémi Choquet Cécile Carrié

1. Despite a growing interest in wildlife disease ecology, there is a surprising lack of knowledge about the exposure dynamics of individual animals to naturally circulating infectious agents and the impact of such agents on host life-history traits. 2. The exploration of these questions requires detailed longitudinal data on individual animals that can be captured multiple times during their life but also requires being able to account for several sources of uncertainty, notably the partial observation or recapture of individuals at each sampling occasion. 3. We use a multi-year dataset to (i) assess the potential effect of exposure to the tick-borne agent of Lyme disease, Borrelia burgdorferi sensu lato (Bbsl), on adult apparent survival for one of its natural long-lived hosts, the Black-legged kittiwake (Rissa tridactyla), and (ii) investigate the temporal dynamics of individual immunological status in kittiwakes to infer the rate of new exposure and the persistence of the immune response. Using a multi-event modelling approach, potential uncertainties arising from partial observations were explicitly taken into account. 4. The potential impact of Bbsl on kittiwake survival was also evaluated via an experimental approach: the apparent survival of a group of breeding birds treated with an antibiotic was compared with that of a control group. 5. No impact of exposure to Bbsl was detected on adult survival in kittiwakes, in either observational or experimental data. 6. An annual seroconversion rate (from negative to positive) of 1·5% was estimated, but once an individual became seropositive, it remained so with a probability of 1, suggesting that detectable levels of anti-Bbsl antibodies persist for multiple years. 7. These results, in combination with knowledge on patterns of exposure to the tick vector of Bbsl, provide important information for understanding the spatio-temporal nature of the interaction between this host and several of its parasites. Furthermore, our analyses highlight the utility of capture-mark-recapture approaches handling state uncertainty for disease ecology studies.

Colouration in Atlantic puffins and blacklegged kittiwakes: monochromatism and links to body condition in both sexes

Journal of Avian Biology (2013)

Claire Doutrelant Arnaud Grégoire Doris Gomez Vincent Staszewski Emilie Arnoux

Sexual dimorphism is widely used as an indirect measure of the intensity of sexual selection. It is also a way to evaluate whether different selective pressures act on males and females. Dichromatism, defined as a difference in colouration between males and females, may for instance result from selection for crypsis in females and selection for conspicuousness in males. Here, we conducted a study to investigate whether differential sexual selective pressures might act on the colour traits of two colonial seabird species, the Atlantic puffin Fratercula artica and the black‐legged kittiwake Rissa tricactyla. First, we used spectrophotometry and visual modelling to determine whether these presumed monomorphic birds are really monochromatic from an avian perspective (birds and humans have a different vision). Second, we estimated whether some of their colourations have the potential to be sexually or socially selected by determining whether these colourations were related to body condition in males and females, and whether the yellow, orange and red colourations may contain carotenoid pigments. Our results indicated that both species were fully monochromatic from an avian perspective. Moreover, our preliminary analyses suggested that the yellow, orange and red colours of these birds contained carotenoids. Lastly, some indices of colouration were positively linked to estimates of condition. Birds in better condition had redder gape (both species) and bill (puffins). In puffins, the relation between condition and gape colouration was significantly stronger in females than males. By contrast, the size of the gape rosette was larger in males than females. The positive links we found between colour indices and condition, together with the absence of sexual dichromatism, suggest that mutual sexual selection may act in these two species.

Kittiwake eggs viewed by conspecifics and predators: implications for colour signal evolution

Biological Journal of the Linnean Society (2017)

Marie–Jeanne Holveck Arnaud Grégoire Romain Guerreiro Vincent Staszewski Thierry Boulinier

Colour traits evolve under the antagonistic selective pressures of increasing detectability to intended receivers (e.g. conspecifics) while minimizing detectability to unintended receivers (e.g. predators). Primarily selected for camouflage, avian egg coloration has also been suggested to have intraspecific signalling functions. A first step in assessing the relative importance of camouflage/communication requires quantifying detectability for different visual systems, which is rarely done. Here, we compared brightness and colour contrasts of black-legged kittiwake (Rissa tridactyla) speckled and soiled eggs as seen from a distance by conspecifics and their main avian predator, the common raven (Corvus corax). We also examined how egg speckling and soiling deposition on incubated eggs affected egg detectability and egg coloration variability. We found that eggs were detectable by both species, but were more conspicuous to conspecifics than to predators. Egg speckling reduced brightness contrast and increased colour contrast, contributing to reducing detectability by predators while maintaining potential for intraspecific communication, respectively. Soiling reduced egg detectability for both perceivers, but soiled eggs remained more conspicuous to conspecifics than predators. Moreover, soiling did not homogenize the clutch signature of egg colour and speckling, thus allowing intraspecific exploitation of information on female quality that egg coloration may convey or individual clutch recognition. We suggest that further studies of egg colour adaptive functions and evolution should consider all perceivers as well as soiling deposition, an overlooked mechanism that may be favoured by selection against predation.

Evidence of an interannual effect of maternal immunization on the immune response of juveniles in a long‐lived colonial bird

Journal of Animal Ecology (2007)

Vincent Staszewski Julien Gasparini Karen D. McCoy Torkild Tveraa Thierry Boulinier

Summary Little is known about the maternal transfer of antibodies in natural host–parasite systems despite its possible evolutionary and ecological implications. In domestic animals, the maternal transfer of antibodies can enhance offspring survival via a temporary protection against parasites, but it can also interfere with the juvenile immune response to antigens. We tested the functional role of maternal antibodies in a natural population of a long‐lived colonial seabird, the kittiwake ( Rissa tridactyla ), using a vaccine (Newcastle disease virus vaccine) to mimic parasite exposure combined with a cross‐fostering design. We first investigated the role of prior maternal exposure on the interannual transmission of Ab to juveniles. We then tested the effect of these antibodies on the juvenile immune response to the same antigen. The results show that specific maternal antibodies were transferred to chicks 1 year after maternal exposure and that these antibodies were functional, i.e. they affected juvenile immunity. These results suggest that the role of maternal antibodies may depend on the timing and pattern of offspring exposure to parasites, along with the patterns of maternal exposure and the dynamics of her immune response. Overall, our approach underlines that although the transgenerational transfer of antibodies in natural populations is likely to have broad implications, the nature of these effects may vary dramatically among host–parasite systems, depending on the physiological mechanisms involved and the ecological context.

Dynamics of anti-Borreliaantibodies in Black-legged Kittiwake (Rissa tridactyla) chicks suggest a maternal educational effect

Canadian Journal of Zoology (2006)

Julien Gasparini Karen D. McCoy Vincent Staszewski Claudy Haussy Thierry Boulinier

In the presence of parasites, mothers can transfer specific immunoglobulins to their offspring. These antibodies are typically thought to provide protection until the juvenile produces its own immune response, but they may also act to educate the developing immune system so as to prepare the individual for future parasite challenge. We examined this hypothesis in a natural host–parasite system involving the Black-legged Kittiwake ( Rissa tridactyla (L., 1758)), the seabird tick ( Ixodes ( Ceratixodes ) uriae White, 1852), and the Lyme disease bacterium ( Borrelia burgdorferi s.l. (Johnston, 1984)). We compared the dynamics of anti-Borrelia antibodies in chicks between ages 5 and 20 days that received a large amount of maternal anti-Borrelia antibodies to those that did not. The results suggest that the presence of maternal antibodies against Borrelia increases the overall production of anti-Borrelia immunoglobulins by chicks and support the existence of an adaptive maternal effect. Experimental approaches are now called for to better appraise the ecological and evolutionary consequences of the maternal transfer of antibodies in host–parasite interactions.
