Hormones in Invertebrates

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 ...

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.

Biology of the Invertebrates

Is there a real need for another general textbook on invertebrate zoology? I would say no. Indeed, to begin with, there is little scope for imagination in this kind of endeavor since there already exist numerous volumes saying much the same thing about essentially the same organisms. The text in general is adequate in its presentation of the various phyla and each chapter begins with a useful s...

Iridoviruses of Invertebrates

Circular permution Genome is a linear molecule of DNA with different terminal sequences at the population level. Physical maps of such genomes are circular. Covert infection A sublethal infection that causes no obvious changes in the appearance or behavior of the host. Cytopathic effect Alteration in the microscopic appearance of cultured cells following virus infection. MCP Major capsid protei...
