Implication

Field and laboratory experiments show selective predation on seedlings by slugs, suggesting impacts on herb composition.

Key Points

The aim is to investigate how predation by Arion vulgaris affects seedlings of different herb species.
Conducted field experiment with 25 herb species exposed to slugs in a controlled setup.
Measured mortality rates of seedlings at the cotyledon stage after 7 days in the field.
Performed laboratory experiment exposing seedlings of 11 species to slugs for 9 hours at 20 °C.
Analyzed the correlation between field and laboratory mortality rates of seedlings.
Mortality rates of seedlings varied significantly, with some species showing over 95% mortality.
Larger seedlings had higher mortality rates compared to smaller ones.
Mortality patterns differed between therophytes and hemicryptophytes.
Field and laboratory experiments showed a marginally significant correlation in mortality rates.
