Branchiopods
Occasionally, large branchiopods can also be found in rain pools of the eastern and central Austrian lowlands, where topography and climate favour the existence of astatic water bodies. Differences in hydrology, temperature and water chemistry requirements may be reflected in local species compositions and species seasonal appearance.Brachiopods. Brachiopods are rare in modern oceans, but were very common in the past (only 325 living species but more than 12,000 fossil species). The body is covered in a shell that is made of two halves (valves) that are held in place by muscles. The valves can be opened (by the muscles) at one end to allow water in and out of the shell ...

Branchiopods would later have shed ...Different branchiopods have different ecological preferences, and with large taphocoenosis data sets it is possible to determine aspects of the palaeoenvironment. Many cladoceran remains have been accurately identified to species [15,16,17,18]. In contrast, the large branchiopods are rarely used or even recorded in such studies [10,19].After identifying roosts of these species, we used tweezers to scrape faeces from branches, avoiding any contact with soil. The samples were collected with a minimum distance of one meter apart to ...Approximately 800 species of branchiopods are found worldwide in freshwater ponds, lakes, and inland saline waters such as the Great Salt Lake in Utah.

Since most branchiopods produce dormant propagules directly (Cáceres, 1997), the better strategy is to mature and reproduce as soon as possible before the hydroperiod ends (Hildrew, 1985; Brendonck et al., 2000). However, terminating dormancy is complex as regards detecting environmental signals as well as the pressure of synchronizing with ...Our 1995 ‘Checklist of the Anostraca’ covered all species described through 31 December 1993 along with those described in the volume from the Second International Large Branchiopod Symposium (Hydrobiologia 298).This supplement includes new species (14) described through 31 December 1996, one change in rank and one new species …
