Reproduction in two species of arctic arachnids, Pardosa glacialis and Alopecosa hirtipes
I investigated the relationship between clutch size, female size and mass, and clutch mass in two species of arctic spiders, Alopecosa hirtipes and Pardosa glacialis (Araneae: Lycosidae). Female mass and number of young were significantly correlated with female size in both years of the study. Cocoo...

Summary: | I investigated the relationship between clutch size, female size and mass, and clutch mass in two species of arctic spiders, Alopecosa hirtipes and Pardosa glacialis (Araneae: Lycosidae). Female mass and number of young were significantly correlated with female size in both years of the study. Cocoon mass was significantly correlated with female size in 1991 only. These results are discussed within the context of reproductive trade-offs and models of reproductive effort based on size. |
