Sponges (Porifera) are among the earliest evolving metazoans. Their filter-feeding body
plan based on choanocyte chambers organized into a complex aquiferous system is so …

Annelid disparity has resulted in morphological-based classifications that disagree with
phylogenies based on Sanger sequencing and phylogenomic analyses. However, the data …

Background Biomphalaria pfeifferi is the world's most widely distributed and commonly
implicated vector snail species for the causative agent of human intestinal schistosomiasis …

As sentinel species, earthworms such as Eisenia spp. and Lumbricus spp. have been
considered among the best bioindicators or biomonitors for soil ecosystems owing to their …

Current sequencing technologies are making available unprecedented amounts of genetic
data for a large variety of species including nonmodel organisms. Although many …

Trichoplax adhaerens (phylum Placozoa) is a very simple organism that lacks a nervous
system. However, its genome contains many genes essential for neuronal function and …

Abstract Background Earthworms (Crassiclitellata) are a diverse group of annelids of
substantial ecological and economic importance. Earthworms are primarily terrestrial …

Pontoscolex corethrurus is the most widespread earthworm species in tropical and sub-
tropical zones and one of the most studied in soil science. Although, ecological interactions …

Background We have a limited understanding of genomic interactions that occur among
partners for many symbioses. One of the most important symbioses in tropical reef habitats …

Background Populations of the earthworm, Lumbricus rubellus, are commonly found across
