..., respectively. Amphistegina bicirculata preferentially dwells below 30 m depth and can be found alive, in very clear waters, down to 100 m ( Hohenegger, 1995 ; Hallock, 1999 ). Finally, A. papillosa is the deepest dwelling taxon, surviving to at least 130 m (e.g., Hottinger, 1977 ; James et al., 1999...

...%) and Amphistegina bicirculata (0–5.3%). The sediment ( figs. 6D , 6H ) is a skeletal coarse sand to gravel, generally poorly sorted. The grain fraction consists mainly of relict grains, often encrusted by corallinacean algae, along with varying amounts of large red algal nodules and branched fragments...

... operculinoides, Nummulites venosus, Baculogypsinoides spinosus, Amphistegina bicirculata and A. papillosa ( Langer and Hottinger, 2000 ) because no investigations about their northern and southern distribution boundaries have been conducted, nor have the necessary temperature measurements been made. Analogous...

... of reef microfaunas and macrofaunas, although the corals present are small (centimeter size). The very low diversity of the overall fauna suggests initial derivation from a reef-flat environment; the rare occurrence of deeper-water species such as Amphistegina bicirculata resulted from transport...

Two large rotaliines ( Operculina sp. and Calcarina calcar ) are found as single specimens and were omitted from analysis. In addition, two thin amphisteginids, Amphistegina bicirculata and A. papillosa , are present...

These successions of species along an environmental gradient are termed coeno-clines ( Whittaker, 1973 ), and can be used for gradient determination based on species proportions in the form of transfer...
