“…The first consequence seems to be a type of inherited environmental effect that may complicate selection responses in nature (Roach and Wulff 1987;Rossiter 1996), but which was controlled for here. The second consequence can promote cell-lineage selection that may shape the distribution of mutational effects on fitness in modular taxa (Otto and Hastings 1998;Orive 2001).…”

Given intraclonal variation, mitotic cell lineages, rather than sexual offspring, may frequently act as units of selection. Here, we applied artificial selection to such lineages in the branching red seaweed Asparagopsis armata, targeting aspects of clonal growth form and growth-form plasticity that enhance light acquisition on patchy subtidal reefs and predicting that a genetic basis to intraclonal variation may promote significant responses that cannot accompany phenotypic variation alone. Cell-lineage selection increased variation in branch proliferation among A. armata genets and successfully altered its plasticity to light. Correlated responses in the plasticity of branch elongation, moreover, showed that cell-lineage selection may be transmitted among the plasticities of growth-form traits in A. armata via pleiotropy. By demonstrating significant responses to celllineage selection on growth-form plasticity in this seaweed, our study lends support to the notion that intraclonal genetic variation may potentially help clonal organisms to evolve adaptively in the absence of sex and thereby prove surprisingly resilient to environmental change.

“…Likewise, it remains to be tested whether chicks from antibody-positive eggs have higher ¢tness (i.e. whether this maternal-induced defence is adaptive; Rossiter 1996) or whether the transfer of speci¢c antibodies is a side e¡ect of the avian immune system. Protection against Borrelia infection by antibodies of Borrelia duttonii, the causative agent of human relapsing fever, and against Borrelia burgdorferi has been experimentally shown in rodents (Morshed et al 1993;Fikrig et al 1990).…”

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.

“…In the Seychelles warbler, the effect of the genetic mother's heterozygosity on offspring survival appears to be an inherited environmental maternal effect; that is, an environmental effect on the offspring's phenotype that arises as the product of maternal genes and the maternal environment (Rossiter 1996). One possible explanation could be that mothers with low heterozygosity were of lower quality and provisioned offspring less.…”

Abstract. The deleterious effects of inbreeding can be substantial in wild populations and mechanisms to avoid such matings have evolved in many organisms. In situations where social mate choice is restricted, extrapair paternity may be a strategy used by females to avoid inbreeding and increase offspring heterozygosity. In the cooperatively breeding Seychelles warbler, Acrocephalus sechellensis, neither social nor extrapair mate choice was used to avoid inbreeding facultatively, and close inbreeding occurred in approximately 5% of matings. However, a higher frequency of extragroup paternity may be selected for in female subordinates because this did reduce the frequency of mating between close relatives. Inbreeding resulted in reduced individual heterozygosity, which, against expectation, had an almost significant (P ϭ 0.052), positive effect on survival. Conversely, low heterozygosity in the genetic mother was linked to reduced offspring survival, and the magnitude of this intergenerational inbreeding depression effect was environmentdependent. Because we controlled for genetic effects and most environmental effects (through the experimental crossfostering of nestlings), we conclude that the reduced survival was a result of maternal effects. Our results show that inbreeding can have complicated effects even within a genetic bottlenecked population where the ''purging'' of recessive alleles is expected to reduce the effects of inbreeding depression.
