Abstract |
Short-term effects of environmental perturbations on various life history traits are reasonably well documented in birds and mammals. But, in the present context of global climate change, there is a need to consider potential long-term effects of natal conditions to better understand and predict the consequences of these changes on population dynamics. The environmental conditions affecting offspring during their early development may determine their lifetime reproductive performance, and therefore the number of recruits produced by a cohort. In this study, we attempted to link recruitment to natal and recent (previous year) conditions in the long-lived black-browed albatross (Thalassarche melanophrys) at Kerguelen Islands. The environmental variability was described using both climatic variables over breeding (sea surface temperature anomaly) and non-breeding grounds (Southern Oscillation index), and variables related to the colony (breeding success and colony size). Immature survival was linked to the breeding success of the colony in the year of birth, which was expected to reflect the average seasonal parental investment. At the cohort level, this initial mortality event may act as a selective filter shaping the number, and presumably the quality (breeding frequency, breeding success probability), of the individuals that recruit into the breeding population. The decision to start breeding was strongly structured by the age of the individuals and adjusted according to recent conditions. An effect of natal conditions was not detected on this parameter, supporting the selection hypothesis. Recruitment, as a whole, was thus influenced by a combination of long- and short-term environmental impacts. Our results highlight the complexity of the influence of environmental factors on such long-lived species, due to the time-lag (associated with a delayed maturity) between the impact of natal conditions on individuals and their repercussion on the breeding population.

Abstract |
Sex differences in lifespan and aging are widespread among animals. Since investment in current reproduction can have consequences on other life-history traits, the sex with the highest cost of breeding is expected to suffer from an earlier and/or stronger senescence. This has been demonstrated in polygynous species that are highly dimorphic. However in monogamous species where parental investment is similar between sexes, sex-specific differences in aging patterns of life-history traits are expected to be attenuated. Here, we examined sex and age influences on demographic traits in a very long-lived and sexually dimorphic monogamous species, the wandering albatross (Diomedea exulans). We modelled within the same model framework sex-dependent variations in aging for an array of five life-history traits: adult survival, probability of returning to the breeding colony, probability of breeding and two measures of breeding success (hatching and fledging). We show that life-history traits presented contrasted aging patterns according to sex whereas traits were all similar at young ages. Both sexes exhibited actuarial and reproductive senescence, but, as the decrease in breeding success remained similar for males and females, the survival and breeding probabilities of males were significantly more affected than females. We discuss our results in the light of the costs associated to reproduction, age-related pairing and a biased operational sex-ratio in the population leading to a pool of non-breeders of potentially lower quality and therefore more subject to death or breeding abstention. For a monogamous species with similar parental roles, the patterns observed were surprising and when placed in a gradient of observed age/sex-related variations in life-history traits, wandering albatrosses were intermediate between highly dimorphic polygynous and most monogamous species. |

Abstract |
Lichens collected in 2007 on Ile Amsterdam and Ile Saint Paul in the Indian Ocean are reported. The diversity is rather poor, with 77 and 40 species collected, respectively. Of those, the islands share 25 species. Caloplaca amsterdamensis Aptroot & Ertz is newly described. Two species, viz. Lecanora subsulphurata and Opegrapha consimillima are the only other endemic species known from these islands. The lichen flora is distinctly temperate to subtropical, with only a few subantarctic elements. Temperate oceanic islands in other oceans share significantly more species with Ile Saint Paul and/or Ile Amsterdam than the neighbouring subantarctic islands. All previously reports of lichens from these islands have been examined and cross-referenced, leading to the new synonymization of several species previously described from Ile Saint Paul, viz. Buellia sancti-pauli, Caloplaca fulgescens, Lecidea conioptoides, L. parasemopsis, L. sancti-pauli, and Verrucaria aethioboliza. It also transpired that the previous report of the genus Orceolina from Ile Saint Paul is incorrect, with the effect that the genus is still only known from Kerguelen. Nearly all species are new records for Ile Amsterdam and most are new for Ile Saint Paul. Some species, viz. Bacidia arnoldiana, B. egenula, B. fraxinea, C. limonia, C. oasis, C. ulcerosa, Fuscopannaria ignobilis, Pertusaria amarescens, Porina curnowii, Porpidia ochrolemma, Pyrenula laevigata, Scoliciosporum intrusum (with the new synonym S. camptosporum), and Verrucaria dolosa are reported for the first time from the Southern Hemisphere. |
