Life history traits (mean and maximum body length of females, number of embryos per
brood= brood size, embryo diameter, number of broods per female, lifespan of females) for …

" The merits of this work are many. A rigorous integration of phylogenetic hypotheses into
studies of adaptation, adaptive radiation, and coevolution is absolutely necessary and can …

The snail Physella virgata virgata, a widely distributed freshwater pulmonate, was observed
to change its life-history characteristics in the presence of the crayfish Orconectes virilis in …

We have presented a formal model for the quantitative analysis of phylogenetic and specific
effects on the distribution of trait values among species. Total trait values are divided into …

Phenotypic plasticity is the ability of a genotype to modify its phenotypic characteristics in
response to different environments. Theory predicts that adaptive plasticity should primarily …

Demographic and life history characteristics of the intertidal whelk Nucella lapillus were
measured across a wave—exposure gradient to quantify the variation in, and identify the …

Many empirical analyses of life‐history tactics are based on the assumption that
demographic variation ought to be greatest among populations or species living in different …

The reproductive strategy of the salamander Ambystoma talpoideum was studied on an age-
specific basis in five breeding populations using ponds subjected to different annual …

This chapter is an introduction to the Phylum Mollusca and a review of freshwater gastropod
systematics, evolution, regional distribution and diversity, reproduction and life history …

Poecilogony, defined as more than one mode of reproduction within a single species, has
been reported in various invertebrates, including mollusks and polychaetes. Many cases …
