Among the ticks with morphological anomalies were: Argas persicus - fed female with atrophia of the third right leg together with the coxa from the chicken in the hen house (Mfakar Alsrki - Syria); Hyalomma marginatum - partly fed female with complete absence of the fourth right leg, was found on a sheep (Mfakar Alsrki); Ixodes ricinus - partly fed female with asymmetry of the body from the roe - deer (Popielno, province Suwałki); I. ricinus - partly fed female with anomaly in shape of the dorsal disk, was found probably on a cattle in province Kraków.
The cowslip plants (Primula veris L.) in two natural populations in Wielkopolska set fruits in 80% on plants with one generative shoot. Mean number of fruits by a rosette varied from 4.7–9.0. In both populations the mean number of fruits by a scape and the value of a real seed production by a single capsule was higher for rosettes with one scape than for plants with two generative shoots.
