The larval morphology of three species of Pagurus (Decapoda, anomura) from California
This study is concerned with description of larval stages of Pagurus granosimanus, P. hemphilli and P. hirsutiusculus. All three are found intertidally in Northern California. Descriptions are based on laboratory raised zoea and glaucothoe.

Larval development and life history of Phyllaplysia taylori dall (Opistobranchiata: anaspidea)
… taxa. The taxonomic importance of embryonic or larval morphology has been limited only by the lack of detailed comparative morphological work on development. Fretter (1967) has shown that larval shell characteristics are reliable for taxonomic identification of some British prosobranchs. …

The social environment and the evolution of morphology in the burying beetle, <em>Nicrophorus vespilloides</em>
… how these various social interactions influence morphology at these different lifestages. I start by investigating how the social environment influences morphological evolution of offspring, by collecting data from replicate experimental populations that had been evolving for 39 generations in …

Larval dispersal and population connectivity: implications for offshore renewable energy structures
… MRED arrays could provide stepping-stones for larval dispersal, mediating species range expansions or invasions. As common members of hard-substrate fouling communities and likely colonisers of MREDs, the larval dispersal processes of barnacles (Cirripedia: Thoracia) in the Firth of Lorn …

Estudos comparados sobre morfologia de imaturos e comportamento de Sphecinae (Insecta: Hymenoptera: Sphecidae)
… work is comparatively studying the immature morphology and the nesting behaviour of species of Sphecinae, in a way to contribute to the understanding of the phylogeny of the group and discussing about hypotheses related to the evolution of the behavioural pattems. A key to genera and …

Larval development and feeding ecology of Hermissenda crassicornis (Eschscholtz) and Aeolidia papillosa (Linnaeus)
… a classification of metamorphic types based on larval shell type (Thompson, 1961) and on larval feeding behavior (ie. lecithotrophic vs. planktotrophic larvae). I agree with Thompson's (1967) distinction between direct and lecithotrophic developmental types in the sense that they represent …
