SummaryTwo species of invertebrates, Parachaeraps bicarinatus, a freshwater crayfish, and Helix pomatia, a garden snail, were examined for the presence of cells which could phagocytose particulate material introduced into their vascular systems. By means of blood clearance studies and histological techniques, it was demonstrated that there existed a ...

Masking effects are a common feature of daily rhythmicity in invertebrates; and, particularly with respect to activity/rest cycles in arthropods and mollusks, there are numerous examples of masking in response to external environmental stimuli. Internal masking, in which endogenous processes modulate circadian patterns, has also been documented in a ...

Octopamine (OA), a biogenic monoamine structurally related to noradrenaline, acts as a neurohormone, a neuromodulator and a neurotransmitter in invertebrates. It is present in relatively high concentrations in neuronal as well as in non-neuronal tissues of most invertebrate species studied. It functions as a model for the study of modulation in general.

We have characterized a prodynorphin-like molecule in an invertebrate, specifically in the rhynchobdellid leech Theromyzon tessulatum. The 14270 Da protein was purified by gel permeation chromatography, anti-leucine-enkephalin-affinity column separation followed by reverse-phase HPLC.

The aquatic invertebrates of Amazonian floodplains can be divided into three large communities: the zooplankton, the benthos and the perizoon. Most studies deal with zooplankton, concentrating on taxonomic aspects and on community structure during the hydrological cycle.

Invertebrates in neurotoxicology
Acta Biologica Hungarica, 2000Due to the relative simplicity of their nervous system, invertebrate animals were widely used in the past decades for studying the processes of excitability at membrane level, as well as the mechanisms of neuronal events and interneuronal communication. Parallel with investigating basic questions of neurobiology, lower animals have also been the object

Runx genes have been identified in all metazoans and considerable conservation of function observed across a wide range of phyla. Thus, insight gained from studying simple model organisms is invaluable in understanding RUNX biology in higher animals. Consequently, this chapter will focus on the Runx genes in the diploblasts, which includes sea anemones
