Vertebrate Protein and Peptide Hormones
2016When analyzing invertebrates in the 1930s and 1940s, Berta and Hans Schaller developed the idea of neurosecretion using the large oceanic snail A. californica (Califonia sea hare) with its few and relatively large neurons. Neuropeptides have been found in all metazoans. Where whole genome sequences are available such as in bees A.

Gonadotropin-releasing hormone in invertebrates: Structure, function, and evolution
General and Comparative Endocrinology, 2006Gonadotropin-releasing hormone (GnRH) is central to the initiation and maintenance of reproduction in vertebrates. GnRH is found in all major groups of Phylum Chordata, including the protochordates. Studies on functional and structural evolution of GnRH have, in the past, focused exclusively on chordates.

The Complex of Steroid Hormones in Invertebrate Hydrobionts
Biologiâ vnutrennih vodThe presence of a complex of biologically active steroid compounds (BASC) – hydrocortisone, corticosterone, progesterone, testosterone and estrogens (vertebrate hormones) in invertebrate hydrobionts of different phylogenetic levels was revealed in the experiments.

Invertebrate Systems for the Study of Hormonal Effects on Behavior
1978Publisher Summary This chapter discusses invertebrate systems for the study of hormonal effects on behavior. It has long been known that hormones can have profound effects on behavior. The most familiar examples of these effects are the changes that occur in many vertebrates during their breeding seasons.

Chromatographic Detection and Immunoassay of Invertebrate Hormones
1974Bioassays of invertebrate hormones continue to serve a very useful purpose, but other approaches to detection that could become more specific and sensitive have been explored and are beginning to yield encouraging results. Principal alternatives that have been used both for isolation and identification of these hormones and analogs are radioimmunoassay
