Previous estimates of a generic level phylogeny for the ubiquitous parasitoid wasp subfamily
Microgastrinae (Hymenoptera) have been problematic due to short internal branches deep …

Calyptraeid gastropods are well know for the taxonomic difficulties caused by their simple,
phenotypically variable shells. In this paper I demonstrate that what was previously …

When building the tree of life, variability of phylogenetic signal is often accounted for by
partitioning gene sequences and testing for differences. The same considerations, however …

Despite the great abundance and diversity of molluscs, only a few have attained “model
research organism” status. One of those species is the slipper snail Crepidula fornicata. Its …

Specimens of four sympatric intertidal limpet species (Siphonaria dayi, S. tenuicostulata, S.
anneae and S. nigerrima) were collected from four localities on the east coast of South Africa …

In recent decades, rapid coastal development has threatened the scarce seagrass beds.
Therefore, more comprehensive research on the ecosystem of the seagrass beds in Penang …

In marine invertebrates, polymorphism and polyphenism in mode of development are known
as “poecilogony.” Understanding the environmental correlates of poecilogony and the …

Crepipatella occulta n. sp. is described from the intertidal zone in northern Chile. This
species is morphologically cryptic with two other Crepipatella species from Chile …

Species invasions are occurring at an increasing rate in coastal environments. Accurately
identifying introductions is a critical issue to take full advantage of the new invasion …
