Spatial properties of landscapes modify the abundance and diversity of most animal assemblages in ways that need to be understood to plan and implement conservation initiatives, and evaluate their effectiveness. Seascape context (i.e. the spatial arrangement of ecosystems) mediates the effects of reserves on fish abundance, species richness and ecological processes in shallow coral reef and man...

nae of granular endoplasmic reticulum, dark cells with flattened cisternae, dark cells filled with colloid particles, and altered and destroyed cells. The ordinary type cells have previously been described in the thyroid during metamorphosis, whereas the unusual type has been overlooked. It was suggested that the two types of dark cells correspond to Langendorff's colloid cells and that all the...
