“…High levels of ionizing solar radiation in alpine habitats might be supposed mutagenic, and yet parthenogenetic and inbreeding plants are common there (5,66). In plants more generally, the association of diminished or abandoned sexuality with the colonizing habit is particularly obvious (18,(67)(68)(69)(70)(71)(72)(73)(74)(75). This, as already mentioned, favors both theories against many of the alternatives.…”

Darwinian theory has yet to explain adequately the fact of sex. If males provide little or no aid to offspring, a high (up to 2-fold) extra average fitness has to emerge as a property of a sexual parentage if sex is to be stable. The advantage must presumably come from recombination but has been hard to identify. It may well lie in the necessity to recombine defenses to defeat numerous parasites. A model demonstrating this works best for contesting hosts whose defense polymorphisms are constrained to low mutation rates.A review of the literature shows that the predictions of parasite coevolution fit well with the known ecology of sex. Moreover, parasite coevolution is superior to previous models of the evolution of sex by supporting the stability of sex under the following challenging conditions: very low fecundity, realistic patterns of genotype fitness and changing environment, and frequent mutation to parthenogenesis, even while sex pays the full 2-fold cost.Parasite coevolution will be shown to be superior to previous models of the evolution of sex by supporting the stability of sex under the following challenging conditions.

“…Certain weed species can be controlled with biological agents (Cullen et al, 1973;Daniel et al, 1973;Phatak et al, 1983;Woodhead, 1981). The vacated niche will, however, be filled by other species not susceptible to the agent (Putnam, 1990).…”

“…Natural enemies can be spectacular control agents (Dodd 1940;Huffaker and Kennett 1959;Cullen et al 1973;Room 1990) but it is still nearly impossible to predict whether an agent will establish in its new host range and whether, if it does, it will have an impact on the population of the pest (Elton 1958;Crawley 1986;Drake et al 1989;Kareiva 1996;Williamson 1996;Shea and Possingham 2000). Ultimate success in the field will be determined by how insects released for biological control locate and respond to their host populations.…”

Effect of patch size and plant density of Paterson"s curse ( Echium plantagineum ) on the oviposition of a specialist weevil, Mogulones larvatus

This study examines the oviposition response of a specialist weevil (Mogulones larvatus) to patches of its host, the noxious weed Paterson"s curse/salvation Jane (Echium plantagineum). We simultaneously examined the effect of patch size and plant density (and their interaction), on the recorded oviposition patterns. Our results show that oviposition first occurred on the largest patches with the highest number of plants. However, there was no significant effect of patch size or number of plants per patch at the end of the experiment. At this time the level of attack per plant was negatively correlated with plant density. This negative effect of density on the level of oviposition was not mediated by a reduction in plant size at higher densities. The pattern observed may indicate a risk-spreading strategy by females.
