Aerobic And Anaerobic Degradation And Mineralization Of C-14 Chitin By Water Column And Sediment Inocula Of The York-River-Estuary, Virginia, Jn Boyer Jan 1994

Aerobic And Anaerobic Degradation And Mineralization Of C-14 Chitin By Water Column And Sediment Inocula Of The York-River-Estuary, Virginia, Jn Boyer

VIMS Articles

Potential rates of chitin degradation (C(d)) and mineralization (C(m)) by estuarine water and sediment bacteria were measured as a function of inoculum source, temperature, and oxygen condition. In the water column inoculum, 88 to 93% of the particulate chitin was mineralized to CO2 with no apparent lag between degradation and mineralization. No measurable dissolved pool of radiolabel was found in the water column. For the sediment inocula, 70 to 90% of the chitin was degraded while only 55 to 65% was mineralized to CO2. C-14 label recoveries in the dissolved pool were 19 to 21% for sand, 17 to 24% …


Vertical Migration Of Blue Crab Callinectes Sapidus Megalopae: Implications For Transport In Estuaries, Ej Olmi Jan 1994

Vertical Migration Of Blue Crab Callinectes Sapidus Megalopae: Implications For Transport In Estuaries, Ej Olmi

VIMS Articles

Following larval development in coastal waters, postlarvae (megalopae) of the blue crab Callinectes sapidus Rathbun enter inlets and, against the net seaward flow of estuarine waters, move upstream to juvenile habitats. Abundance and vertical distribution of blue crab megalopae in the York River, Virginia, USA, a subsetuary of Chesapeake Bay, was quanitified to examine the hypothesis that megalopae are not transported simply as passive particles, but display behaviors that augment their immigration. Megalopal abundance and depth distribution and environmental variables were measured at shallow (3 to 4 m) sites in 1988 and 1989 and at a deep (10 m) site …
