Cascading Disturbances in Florida Bay, USA: Cyanobacteria Blooms, Sponge Mortality, And Implications For Juvenile Spiny Lobsters Panulirus Argus
TLDR
It is confirmed that the sponge die-off was widespread and its occurrence coincided with areas that had been exposed to the cyanobacteria bloom, and this cascade of disturbances has dramatically altered the community structure of affected hard bottom areas and demonstrates the coupled dynamics of this shallow marine ecosystem. Expand
Life history of the spotted spiny lobster, Panulirus guttatus, an obligate reef-dweller
TLDR
Population dynamics of the spotted spiny lobster, Panulirus guttatus, were examined at Looe Key Reef, Florida, USA, from April 1987 to August 1989; Adults sheltered within the reef during the day and foraged on top of the reef at night. Expand
Population dynamics of juvenile Caribbean spiny lobster, Panulirus argus, in Florida Bay, Florida
TLDR
It is indicated that lobsters in some areas in Florida Bay can reach Florida's legal harvestable size (76 mm CL) 1.5 years after settlement, and the relationship between recruitment and immigration of juveniles and postlarvae is stronger than was previously believed. Expand
Nocturnal foraging of the Caribbean spiny lobster (Panulirus argus) on offshore reefs of Florida, USA
TLDR
It is concluded that Panulirus argus can forage successfully wherever suitable prey items, especially molluscs, are abundant, however, where a wide range of substrata, including rubble, is available, rubble is preferred because of its abundant, accessible prey. Expand
Evaluation of effort reduction in the Florida Keys spiny lobster, Panulirus argus, fishery using an age-structured population analysis
TLDR
Age-structured analysis of the catches-at-age indicated that fishing mortality decreased by 16%, even as landings increased, and it is not known whether the increase in landings was due to natural population fluctuations or to positive results of trap reduction. Expand
Overgrazing of a large seagrass bed by the sea urchin Lytechinus variegatus in Outer Florida Bay
TLDR
Effects of the removal of seagrass biomass have already resulted in the depletion of epifaunal-infaunal mollusk assemblages and resuspension of fine-grained surface sediments-which have caused significant changes in community structure and in the physical properties of the sediments, and may lead to additional, longer-term, indirect effects that may extend beyond the boundaries of the grazed areas and into adjacent coastal ecosystems. Expand
Role of physical refugia: implications from a mass sponge die-off in a lobster nursery in Florida
TLDR
The availability of alternative, previously underused shelter in the affected region, continued production in the larger unaffected nursery region, and high postlarval supply that fortuitously coincided with sponge loss all offset a stronger effect. Expand
Factors Affecting the Recruitment of Juvenile Caribbean Spiny Lobsters Dwelling in Macroalgae
TLDR
The results imply that the population dynamics ofjuvenile P argus dwelling in macroalgae are not typically regulated by density-dependent processes, although density- dependent predation may be locally important in patches when settlement is episodically high. Expand
Factors Affecting Growth and Maturation of Spiny Lobsters, Panulirus argus, in the Florida Keys
TLDR
Overall growth rates of sublegal-sized and large ( CL) spiny lobsters, Panulirus argus, in the Florida Keys were lower in winter than in summer; changes in growth rates signified a shift in energy use at onset of maturation. Expand
