Benthic Invertebrate Community Structure
Fundamental to the scientific method is the use of controls or control conditions against which results obtained under test conditions are compared. In field studies, all variables cannot be controlled and replicates cannot be randomly assigned to treatments, so an attempt is made to choose test and control conditions (often represented by different sites) that are as similar as possible; the v...
متن کاملInvertebrate Neuroglia-junctional Structure and Development
The morphological characteristics of the neuroglial cells of invertebrates are reviewed, including the ultrastructural and enzyme cytochemical features of their cell bodies and attenuated cytoplasmic processes, the various ways they ensheath the nerve cells, including the loosely myelinated condition, their modifications due to intraganglionic localization and their interactions with other glia...
متن کاملEvolutionary trends in invertebrate ganglionic structure
Early Bilateria developed the basic characteristics of ganglionic organization. Features such as the divergence of longitudinal axon bundles into functionally unique tracts, the separation of centers for motor pattern generation and exteroceptive sensory integration, the segregation of limb motor centers to lateral neuropils, and the genesis of glomerular microarchitecture occur in representati...

متن کاملInvertebrate Immunity. Mechanisms of Invertebrate Vector-Parasite Relations
effects of aldosterone on its target organ; renal handling of calcium and phosphate is discussed only superficially (other ions do receive more careful attention); acid-base balance is mentioned in a single page under the heading "Control of the Urinary pH." On the whole, however, the discussion of physiology is fair, if less than comprehensive, and serves nicely to complement the more thorough...
