Evolution of two novel feeding strategies among caenogastropod molluscs, suspension feeding in calyptraeids such as Crepidula fornicata and predatory feeding with a pleurembolic proboscis among neogastropods, may have both involved elongation of the anterior esophagus. Emergence of predatory feeding with a proboscis is particularly significant beca...
Developmental modularity may facilitate morphological evolution by allowing
phenotypic change of a developing body component without negatively impacting other
components. I examined foregut development in Amphissa columbiana, a predatory
neogastropod with a highly derived foregut and in Crepidula fornicata, a phytoplanktonfeeder with a less derive...
Long viewed as a mostly noble, atmospheric species, recent work demonstrates that nitrogen in fact cycles throughout the Earth system, including the atmosphere, biosphere, oceans, and solid Earth. Despite this new-found behaviour, more thorough investigation of N in geologic materials is limited due to its low concentration (one to tens of parts pe...
