Intra- and intersexual differences in parasite resistance and female fitness tolerance in a polymorphic insect
To understand host-parasite interactions, it is necessary to quantify variation and covariation in defence traits. We quantified parasite resistance and fitness tolerance of a polymorphic damselfly (Ischnura elegans), an insect with three discrete female colour morphs but with monomorphic males. We quantified sex and morph differences in parasite resistance (prevalence and intensity of water mi...
متن کاملIntersexual conflict in spiders
Reproductive strategies of males and females usually differ and. as a consequence, may impose asymmetric costs of reproduction on tire two sexes and result in conflict between the sexes. In spiders, males do not provide parental care and females can store sufficient sperm for several clutches. These characteristics define the stage for a conflict between males and females that occurs mainly ove...
متن کاملInduced Mutations in Habrobracon Eggs
S long ago as 1921 HOLTHUSEN observed an effect of anoxia on X-rayed A cells. Interest in this factor and its relation to radiation damage has recently been revived. BACQ (1951) has reviewed the earlier work and latest developments have been described by HOLLAENDER, BAKER and ANDERSON (1951), HOLLAENDER (1952) and GILES (1952). One group of investigators has been concerned with the question as ...
متن کاملMale dominance, female mate choice, and intersexual conflict in the rose bitterling (Rhodeus ocellatus).
An intersexual conflict arises when males and females differ in their reproductive interests. Although experimental studies have shown that females often mate with dominant males, it may not always be in the interest of a female to do so. Here we investigated the impact of male dominance on female mate choice and offspring growth and survival in the rose bitterling (Rhodeus ocellatus), a freshw...
متن کاملIntersexual partial diploids of phycomyces.
Sexual interaction between strains of opposite sex in many fungi of the order Mucorales modifies hyphal morphology and increases the carotene content. The progeny of crosses of Phycomyces blakesleeanus usually include a small proportion of anomalous segregants that show these signs of sexual stimulation without a partner. We have analyzed the genetic constitution of such segregants from crosses...
