摘要: Summary Postembryonic ontogenetic development in Porcellio scaber was observed on an individual basis over 90 weeks. Under optimal nutritive conditions, the duration of to maturity showed high inter-individual variability and ranged from 60 Both growth rates mortality juvenile woodlice depended available food source, alder litter being highest, oak lowest, birch intermediate quality. The experimentally manipulated pH level that, turn, affected some leaf traits density activity litter-colonizing microbiota minor significance. Previous results present study suggest that sources low value affect isopod populations by (1) increasing (2) reducing reproductive success adult females, (3) juveniles, therefore (4) delayed maturity.
