“…As a result, even when individuals breed at an optimal level of reproductive effort, there would arise a positive correlation between environmental condition and adult survival, as observed in this study. [28][29][30][31][32][33] Our study and that of Boekelheide & Ainleyl°p rovide evidence suggesting that juvenile survival varies among cohorts. It is not possible to untangle the different components of juvenile return rate (survival in the first, second and third years of life, natal philopatry), but because return rate was correlated with sea surface temperature (SST) measured in March of the first year of life, this suggests that first-year survival was affected by oceanographic conditions.…”

The ~nfluence of a trawling moratorium on the breedlng ecology of Audouin's gulls (Larus audouinii Payraudeau) was investigated during 1992 and 1993 in the largest colony of the species in the world (70% of total population), at the Ebro Delta, NE Spain. western Mediterranean. In this colony, Audouin's gull behaves partly as a scavenger following the trawling fleet and exploiting fishing discards. Each year, the trawling moratorium affected different breeding stages of the species: in 1992 it overlapped with pre-laying and laying stages, while in 1993 it affected most of the chick-rearing stage. We examined differences in laying dates, laying interval, clutch and egg slzes, nest desertion during laying, hatching success, hatchling mass and condition, growth rates, chick survival and breeding success. The moratorium greatly affected egg production in 1992, delaying the start of l a y~n g and dramatically decreasing clutch and egg sizes. Intraclutch egg size variation between the 2 years suggests that egg size profiles are outcomes of the interaction between physiological and environmental factors rather than the result of ultimate factors. Nest desertion was much higher in 1992, probably because some females were under a critical body condit~on threshold and they deserted after laying the first egg. Hatching success also decreased significantly during 1992, probably related to changes in the size and the quality of the eggs. Chick growth and survivorship was h~g h e r in 1992, when trawler discards were normally available, than in 1993. Trawler discard availability during chick rearing was more important than egg size in determining chick survival. However, differences were not always significant, since In 1993 the n~oratorium did not start until the chicks were 1 wk old, and, further, chicks had h~g h e r skeletal size and body condition (in order of Importance) than In 1992. In fact, chicks had similar fledgling condition in both years at the end of the reanng stage. In 1993, the overall breeding success decreased by 4 8 % Nevertheless, gulls' breed~ng performance for the 2 years was much lower than before the establishment of the flrst moratorium In 1991, and the situation suggests that clupeo~ds, the prey on wh.ich Audouin's gull feed, are scarce. It seems that gulls were not able to compensate for the lack of trawler discards during egg production, since the avallablllty of secondary feeding resources was much lower in March and April (pre-laying and laying stages) than in June (chick-rearing stage). Although in long-lived species a decrease in food supply should affect fecundity before affecting adult survival, results confirm the importance of the trawler fleet activity for the conservat~on of this threatened species.

“…It has previously been shown that tick prevalence and abundance are autocorrelated in both space and time at the scale of the host breeding cli¡ (Danchin et al 1998;McCoy et al 1999). As kittiwakes, like many seabirds, are highly philopatric to their breeding sites between years (Coulson & Thomas 1985), ticks become a predictable part of their breeding environment. Given this, we expected a positive correlation between the prevalence and abundance of ticks present in a breeding cli¡ and the proportion of clutches with antibodies to Borrelia.…”

Mothers are predicted to invest in their o¡spring depending on the quality of their mate, their opportunity to invest in future reproduction and the characteristics of the habitat in which their o¡spring will be born. Recent studies have suggested a transfer of maternal immunity to o¡spring as an induced response to the local presence of parasites in the environment, but evidence has been indirect. Here, we show the presence of antibodies against the Lyme disease agent Borrelia burgdorferi sensu lato, a spirochaete transmitted by the seabird tick Ixodes uriae, in the eggs of kittiwakes Rissa tridactyla. We report higher prevalence of antibodies against Borrelia in eggs from breeding areas with higher prevalence and abundance of ticks. Further, high repeatabilities of antibody-positive eggs within clutches and between ¢rst and replacement clutches show that, within a breeding season, females di¡er consistently with respect to the expression of this induced maternal response. Our results suggest that mothers can alter investment in their young depending on local conditions. Such maternal e¡ects clearly have implications for the ecology and evolution of host^parasite interactions.
