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 ...

Publisher Summary The chapter discusses the viruses of invertebrates. The great majority of the viroses described among the invertebrates occur in the Insecta. In the Lepidoptera, newly found nuclear polyhedroses, intestinal cytoplasmic polyhedroses, and granuloses have been added to the list of inclusion body viroses.

Chronobiology International, 1989
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 ...

Progress in Neurobiology, 1999
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.

GnRH in the invertebrates: an overview
2002Publisher Summary This chapter provides an overview of GnRH in the invertebrates. The gonadotropin-releasing hormone (GnRH), which was previously called luteinizing hormone-releasing hormone (LHRH), represents a pivotal peptide in animal reproduction.

Lamins are the main component of the nuclear lamina and considered to be the ancestors of all intermediate filament proteins. They are localized mainly at the nuclear periphery where they form protein complexes with integral proteins of the nuclear inner membrane, transcriptional regulators, histones and chromatin modifiers.

Veterinary Clinics of North America: Exotic Animal Practice, 2004
Invertebrates are attracting increasing interest within the veterinary profession. They are also significant in their own right; as the Council of Europe's "Charter on Invertebrates" points out, they are the most important component of wild fauna as well as providing food, contributing to agriculture and forestry, and aiding medicine,industry, and ...

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.
