Zoology: Invertebrates that Parasitize Invertebrates

The genome of an orthonectid, a group of highly modified parasitic invertebrates, is drastically reduced and compact, yet it shows the bilaterian gene toolkit. Phylogenetic analyses place the enigmatic orthonectids within Spiralia, although their exact placement remains uncertain.

Perspective: Research Activity of Enteropancreatic and Brain/Central Nervous System Hormones Across Invertebrates and Vertebrates1

SYNOPSIS. During the past two decades there have been rapid advances in our knowledge of the structure and function of the protein hormones in the brain and gastroenteropancreatic system (GEP). Many published articles have highlighted the superfamily of hormonal peptides, specifically, the mechanisms and control of peptide synthesis in neural and non-neural tissues, and gene structure. Here we ...

Operant conditioning in invertebrates.

Learning to anticipate future events on the basis of past experience with the consequences of one's own behavior (operant conditioning) is a simple form of learning that humans share with most other animals, including invertebrates. Three model organisms have recently made significant contributions towards a mechanistic model of operant conditioning, because of their special technical advantage...
