Phosphorus cycling by mussels (Unionidae: Bivalvia) in Lake St. Clair, and in mussel tissue, and by measuring rates of biodeposition and excretion. Mean rates of biodeposition and excretion for ., the most abundant species, were 6.3 μg P (g shell-free dry wt)-. h-. and 1.3 μg P (g shell-free dry wt)-. h-., respectively; body tissue phosphorus content was 2.7 percent o遍及 发表于 2025-3-30 21:08:57
