    Notes: [Auszug] SIR - Vane-Wright suggests1 that one of the most telling points against batesian mimicry is likelihood, on the grounds that chemical defence is more likely to evolve because it provides more reliable protection. We are not aware of any evidence that this argument is valid. Evolution is ...

    Acquisition of immunity in cattle against the blue tick,Boophilus decoloratus (1991)

    Notes: Abstract It is well known that ixodid ticks have the ability to induce immunity in their host. We demonstrate, for the first time, that the tickBoophilus decoloratus induced immunity in its bovine host, since the mean weight of engorged females fed on naive animals dropped from 201.5 mg, to 173.7 mg and 155.3 mg, for females fed on calves previously exposed once and twice, respectively, toB. decoloratus infestations. Ticks which had been transferred from one individual host to another one were able to complete their feeding period on a sensitive host. Such ticks were significantly heavier ( $$\bar x$$ 245.2 mg) than those fed on a naive ( $$\bar x$$ 201.5 mg) host for the entire normal feeding period. A negative correlation between the mean weight of the engorged female ticks and the level of serum gamma globulins in the host was also demonstrated.
