Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

Reproductive inequalities in the acanthocephalan Corynosoma cetaceum: looking beyond "crowding" effects [PDF]

open access: yes, 2018
Background: At present, much research effort has been devoted to investigate overall (average) responses of parasite populations to specific factors, e.g., density-dependence in fecundity or mortality. However, studies on parasite populations usually pay
