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.

Invertebrates in neurotoxicology [PDF]
Acta Biologica Hungarica, 2000 Due 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

Regeneration in invertebrates [PDF]
RENDICONTI LINCEI, 2008 The mechanisms of regeneration are reviewed from a genetic, cytological and molecular biological points of view. Planarians and Hydra have been chosen and illustrated as biological examples.

Is there “pain” in Invertebrates?
Behavioural Processes, 1986In contrast to nociception, the perception of pain, or pain experience, remains a subjective notion applicable to humans, but untestable with animals. Yet, when defined operationally as a physiological response induced in an animal by stimuli painful to humans, and resulting in a protective stimulus avoidance response, pain is amenable to testing with ...

Feeding Ecology of Stream Invertebrates
, 1979A review of various aspects of invertebrate-microbial interactions is presented. Food resources of stream invertebrates are distinguished by particle size (detritus), the presence of chlorophyll (periphyton), and high protein content (macrophytes ...

Veterinary Clinics of North America: Exotic Animal Practice, 2004
In this article, "Invertebrates" are considered to be all those animals that are not in the five main groups of vertebrates (Mammalia,Aves, Reptilia, Amphibia, and three classes of fish), and the term neoplasm is used in its traditional sense of "new, uncontrolled, growth".

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.

Veterinary Clinics of North America: Exotic Animal Practice, 2020
Invertebrates are becoming more popular and, as collections age, clients may seek veterinary intervention where the welfare of the animal must be considered. This article covers aging in many invertebrate species but with a focus on species likely to be seen in general practice.

Local adaptation in marine invertebrates.
Annual Review of Marine Science, 2011Local adaptation in the sea was regarded historically as a rare phenomenon that was limited to a handful of species with exceptionally low dispersal potential. However, a growing body of experimental studies indicates that adaptive differentiation occurs
