Lobster Movements In Response To A Hurricane, Steven H. Jury, W. Huntting Howell, Winsor H. Watson Iii Mar 1995

Lobster Movements In Response To A Hurricane, Steven H. Jury, W. Huntting Howell, Winsor H. Watson Iii

Jackson Estuarine Laboratory

There are several anecdotal reports of the American lobster Homarus americanus moving to deeper water, or suffering increased mortality, in response to storm events. It has also been reported that changes In salinity and temperature, similar to those result~ng from storm events, can elicit avoidance behaviors. In 1991, during an ongoing lobster study, Hurricane Bob caused a substantial drop in salinity in the Great Bay Estuary, New Hamphlre, USA. This freshet, and possibly related environmental perturbations, was associated with increased movement of lobsters down the estuary toward the coast and a rise in catch in areas closer to the coast. …

Photosynthetic Responses Of Florida Seaweeds To Light And Temperature: A Physiological Survey, Arthur C. Mathieson, Clinton J. Dawes May 1986

Photosynthetic Responses Of Florida Seaweeds To Light And Temperature: A Physiological Survey, Arthur C. Mathieson, Clinton J. Dawes

Jackson Estuarine Laboratory

The photosynthetic responses of 37 tropical seaweeds (14 Chlorophyceae, 5 Phaeophyceae and 18 Rhodophyceae) were measured in a Gilson Warburg Apparatus under a variety of light and temperature regimes. The brown algae Padina vickersiae and Sporochnus pedunculatus exhibited the lowest saturation light intensity (263 μE/m2/sec), while five green algae (Acetabularia crenulata, Cladophora coelothrix, Dictyosphaeria cavernosa, Monostroma oxyspermum and Codium repens) had the highest light optima (3,843–4,258 μE/m2/sec). Overall, the Chlorophyceae exhibited the broadest range of light optima; in contrast, the Phaeophyceae primarily had low light optima, while several Rhodophyceae had higher light …

Seasonal Studies Of Florida Sublittoral Marine Algae, Arthur C. Mathieson, Clinton J. Dawes Jan 1975

Seasonal Studies Of Florida Sublittoral Marine Algae, Arthur C. Mathieson, Clinton J. Dawes

Jackson Estuarine Laboratory

The seasonal occurrence and reproduction of the sublittoral seaweed populations at four Florida sites are described. A total of 180 taxa were collected, including 105 Rhodophyceae, 49 Chlorophyceae, and 26 Phaeophyceae. The two southern sites in the Florida Keys showed higher numbers of species than the two northern sites off the central West Coast of Florida. The red algae were the most diverse group at each site. Green algae were more numerous than brown algae at the two Florida Key sites. Several of the species recorded represent extensions of known distributional ranges. Peak numbers of species were recorded during the …
