Population-level effects of fitness costs associated with repressible female-lethal transgene insertions in two pest insects
Genetic control strategies offer great potential for the sustainable and effective control of insect pests. These strategies involve the field release of transgenic insects with the aim of introducing engineered alleles into wild populations, either permanently or transiently. Their efficacy can therefore be reduced if transgene-associated fitness costs reduce the relative performance of releas...
متن کاملFitness costs in spatially structured environments.
The clustering of individuals that results from limited dispersal is a double-edged sword: although it allows for local interactions to be mostly among related individuals, it also results in increased local competition. Here I show that, because they mitigate local competition, fitness costs such as reduced fecundity or reduced survival are less costly in spatially structured environments than...

متن کاملQuasi-Incestuous Paliyan Marriage in Comparative Perspective
Quasi-incestuous marriages of South Indian Paliyan foragers are described and compared with broadly similar arrangements in nine other cultures. Twelve percent of Paliyan marriages occur through pedogamous union with stepand adopted children, some calling this their preferred form of marriage. Paliyan subsistence, households, types of marriage, and pedogamy are described. Although two sample cu...
متن کاملOccasional Identity or Occasional Reference ?
André Gallois argues that individuals that undergo fission are on some occasions identical, but on others distinct . occasional identity however, is metaphysically costly . i argue that we can get all the benefits of occasional identity without the metaphysical costs . on the proposed account, the names of ordinary material objects refer indeterminately to stages that belong to reference classe...
