Deuterostome phylogeny reveals monophyletic chordates and the new phylum Xenoturbellida
Deuterostomes comprise vertebrates, the related invertebrate chordates (tunicates and cephalochordates) and three other invertebrate taxa: hemichordates, echinoderms and Xenoturbella. TheExpand

Neuronal Transcriptome of Aplysia: Neuronal Compartments and Circuitry
Molecular analyses of Aplysia, a well-established model organism for cellular and systems neural science, have been seriously handicapped by a lack of adequate genomic information. By sequencing cDNAExpand

Hormonal regulation of the humoral innate immune response in Drosophila melanogaster
SUMMARY Juvenile hormone (JH) and 20-hydroxy-ecdysone (20E) are highly versatile hormones, coordinating development, growth, reproduction and aging in insects. Pulses of 20E provide key signals forExpand

What is metamorphosis?
Metamorphosis (Gr. meta- "change" + morphe "form") as a biological process is generally attributed to a subset of animals: most famously insects and amphibians, but some fish and many marineExpand

Sperm survival in the female reproductive tract in the fly Scathophaga stercoraria (L.).
While sperm competition risk favours males transferring many sperm to secure fertilizations, females of a variety of species actively reduce sperm numbers reaching their reproductive tract, e.g. byExpand

Cross-kingdom hormonal signaling: an insight from thyroid hormone functions in marine larvae
SUMMARY Thyroid hormones (THs) are small, lipophilic signaling molecules built from tyrosine and iodine. TH action is well characterized in vertebrates, where these molecules play a fundamental roleExpand

Thyroid hormone metabolism and peroxidase function in two non-chordate animals.
In mammals, thyroid hormone (TH) signaling is essential for metabolic control, differentiation and homeostasis. These hormones are also involved in the regulation of metamorphosis in amphibians andExpand

Signaling mechanisms underlying metamorphic transitions in animals.
Metamorphosis in many animal groups involves a radical transition from a larval to a juvenile/adult body plan and the challenge of orchestrating 2 overlapping developmental programs simultaneously,Expand

Reduction in morphological plasticity in echinoid larvae: relationship of plasticity with maternal investment and food availability
Hypotheses: If phenotypic plasticity is costly or not beneficial to marine invertebrate larvae, then increased maternal investment into eggs should result in decreased plastic responses. If geneticExpand
