Effects Of Predation Upon The Long-Spined Sea Urchin Diadema Antillarum By The Spotted Spiny Lobster Panulirus Guttatus, Meredith D. Kintzing, Mark J. Butler Iv

Biological Sciences Faculty Publications

Sea urchins, important herbivores in marine ecosystems, are strongly impacted by both the direct and indirect effects of predation, and the long-spined sea urchin Diadema antillarum is no exception. Once abundant on Caribbean coral reefs, D. antillarum populations were decimated by disease in the early 1980s, and only where their natural predators have been over-fished has D. antillarum recovery been observed. Spiny lobsters (Palinuridae) are predators of sea urchins, and although there are several species of spiny lobster in the Caribbean, only the spotted spiny lobster Panulirus guttatus is restricted to coral reefs where D. antillarum dwells. We investigated the …

Oceanography, Geology, Biogeography, And Fisheries Of The Eastern Central Atlantic, Merete Tandstad, Ana Maria Caramelo, Fabio Carocci, Kent Carpenter, Jonnell C. Sanciangco

Biological Sciences Faculty Publications

[Introduction] This species identification guide focuses on the marine species occurring in the eastern Atlantic Ocean from Gibraltar in the north (36°00'N) to the middle of Namibia in the south (23°00'S) and westward to 30°00'W longitude (FAO Fishing Area 34) and to 20°00'W longitude (FAO Fishing Area 47) (Fig 1). Estuarine species, as well as species that only spend part of their life cycle in marine waters (anadromous and catadromous species) are also included.

The West African coast encompasses some of the most productive areas in the world, supporting important fishery resources and a unique diversity. Fisheries constitute an important …

Status Reports Of The Fisheries And Aquatic Resources Of Western Australia 2013/14. State Of The Fisheries, W.J Fletcher, K. Santoro

Status Reports of the Fisheries and Aquatic Resources

The Status Reports of the Fisheries and Aquatic Resources of Western Australia (SRFAR) provide the public with an annual update on the state of the fish stocks and other aquatic resources of Western Australia (WA) managed by the Department of Fisheries (Department). These reports outline the most recent assessments of the cumulative risk status for each of the aquatic resources (assets) within WA’s six Bioregions using an Ecosystem Based Fisheries Management (EBFM) approach.

Distribution And Elimination Of 3-Trifluoromethyl-4-Nitrophenol (Tfm) By Sea Lamprey (Petromyzon Marinus) And Non-Target, Rainbow Trout (Oncorhynchus Mykiss) And Lake Sturgeon (Acipenser Fulvescens), Michael W. Le Clair

Theses and Dissertations (Comprehensive)

The pesticide, 3-trifluoromethyl-4-nitrophenol (TFM), has been highly successful in the control of sea lamprey (Petromyzon marinus) populations in the Great Lakes. Treatments with TFM involve applying it to streams, where it targets larval sea lamprey which live burrowed in the stream substrate. While the toxic mechanism of TFM has been elucidated, and its effects on sea lamprey described, its effects on non-target fish species such as rainbow trout (Oncorhynchus mykiss) and lake sturgeon (Acipenser fulvescens) are not as well understood. The present work demonstrated that rainbow trout show a great capacity to detoxify the lampricide using glucuronidation, when exposed to …

Connecting Model Species To Nature: Predator-Induced Long-Term Sensitization In Aplysia Californica, Maria J. Mason, Amanda J. Watkins, Jordann Wakabayashi, Jennifer Buechler, Christine Pepino, Michelle Brown, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Previous research on sensitization in Aplysia was based entirely on unnatural noxious stimuli, usually electric shock, until our laboratory found that a natural noxious stimulus, a single sublethal lobster attack, causes short-term sensitization. We here extend that finding by demonstrating that multiple lobster attacks induce long-term sensitization (>= 24 h) as well as similar, although not identical, neuronal correlates as observed after electric shock. Together these findings establish long-and short-term sensitization caused by sublethal predator attack as a natural equivalent to sensitization caused by artificial stimuli.
