Contribution to the knowledge of the family Otoplanidae Hallez, 1892 (Rhabditophora, Proseriata) in the Mediterranean [PDF]
, 2009 A growing awareness is rising that present perception of marine biodiversity is inadequate, and based upon unrepresentative data. The inadequacy of knowledge on taxonomy and distribution of marine organisms is particularly acute for interstitial ...

Pan-phylum comparison of nematode metabolic potential [PDF]
, 2015 Nematodes are among the most important causative pathogens of neglected tropical diseases. The increased availability of genomic and transcriptomic data for many understudied nematode species provides a great opportunity to investigate different aspects ...

Classical transmitters and their receptors in flatworms
Parasitology, 2005 The flatworm nervous system employs a wide repertoire of neuroactive substances, including small chemical messengers, the so called classical transmitters, and several types of neuropeptides. A large body of research accumulated over four decades has provided a wealth of information on the tissue localization and effects of these substances, their ...

eLife, 2018 Schistosomes infect more than 200 million people. These parasitic flatworms rely on a syncytial outer coat called the tegument to survive within the vasculature of their host.

Hox and ParaHox genes in Nemertodermatida, a basal bilaterian clade [PDF]
, 2006 Molecular evidence suggests that Acoelomorpha, a proposed phylum composed of acoel and Nemertodermatida flatworms, are the most basal bilaterian animals.

Neuropeptide signalling systems in flatworms
Parasitology, 2005 Two distinct families of neuropeptides are known to endow platyhelminth nervous systems – the FMRFamide-like peptides (FLPs) and the neuropeptide Fs (NPFs). Flatworm FLPs are structurally simple, each 4–6 amino acids in length with a carboxy terminal aromatic-hydrophobic-Arg-Phe-amide motif. Thus far, four distinct flatworm FLPs have been characterized,

The evolutionary origins of volition [PDF]
, 2006 It appears to be a straightforward implication of distributed cognition principles that there is no integrated executive control system (e.g. Brooks 1991, Clark 1997). If distributed cognition is taken as a credible paradigm for cognitive science this in
