Growth of two Pisidium (Bivalvia, Sphaeriidae) species in the laboratory

Oecologia, 1980
Growth of Pisidium casertanum and P. subtruncatum from the profundal of the eutrophic Lake Esrom was followed at four temperatures in the laboratory. The growth rate of both species increased with increasing temperature, but the maximum in P. casertanum was attained at 12° C, instead of at 20° C as in P. subtruncatum.

The distribution and conservation of threatened Sphaeriidae on British grazing marshland

Biodiversity and Conservation, 2005
Freshwater sphaeriid bivalves are poorly known ecologically, particularly uncommon species such as Pisidium pseudosphaerium (UK RDB (Red Data Book) staus = ‘rare’). In the UK, this species occupies grazing marsh where conservation opportunities might be shared with other threatened molluscs. We surveyed sphaeriids including P.

Significance of Litter Size in Musculium Securis (Bivalvia: Sphaeriidae)

Ecology, 1978
Experiments were carried out to determine the effects of population density on the natality of Musculium securis (Prime). Laboratory studies showed that: (1) total recruitment increased with increasing densities of parental stock, to an asymptotic value, (2) that recruitment was greater than the reproductive carrying capacity, and (3) that the total ...

Carbon dioxide output in the respiration of three Pisidium species (Bivalvia, Sphaeriidae)

Oecologia, 1977
The carbon dioxide output in respiration of Pisidium casertanum, P. henslowanum and P. conventus was studied in the laboratory. A closedbottle method was used, and the amount of dissolved inorganic carbon was measured with an infrared gas analyser. The mean value of the constant b in equation R=aW b, where R is the respiration rate and W the ash-free ...
