Fisheries Occasional Publication No.72 - Western Rock Lobster Ecological Effects Of Fishing Research Plan., Rhys Brown
Fisheries occasional publications
The commercial West Coast Rock Lobster Fishery (WCRLF) targets the western rock lobster (WRL), Panulirus cygnus, averaging approximately 10,000 tonnes of lobsters each year. Currently approximately 450 to 500 boats operate in the Fishery in waters ranging from 5 m to 200 m depth adjacent to the Western Australian coast and stretching from Cape Leeuwin in the south to Shark Bay in the north. The Fishery is managed by the Department of Fisheries (DoF) in Western Australia, using an input control system designed to constrain exploitation/fishing effort and deliver sustainable catches. The annual value of the catch is estimated at …
Spots Of Adult Male Red-Spotted Newts Are Redder And Brighter Than In Females: Evidence For A Role In Mate Selection?, Andrew K. Davis, Kristine L. Grayson
Spots Of Adult Male Red-Spotted Newts Are Redder And Brighter Than In Females: Evidence For A Role In Mate Selection?, Andrew K. Davis, Kristine L. Grayson
Biology Faculty Publications
As aquatic adults, eastern red-spotted newts (Notophthalmus v. viridescens) are generally green with two rows of dorsal spots, which vary in number between individuals and range in colour from orange to red. The function of these spots is unknown, but it is possible that they serve as sexual ornamentations and we examined this hypothesis by testing for sexual dimorphism in spot characteristics. We used an image analysis approach that has been used previously with this and other amphibian species to compare the number, size and colour – redness (hue score) and brightness – of spots in 100 male …
Traversing Swanton Road, 1st Ed., James A. West
Traversing Swanton Road, 1st Ed., James A. West
Academic, Government & Associated Organizational Research Resources
Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …
Population Structure Of Coyote (Canis Latrans) In The Urban Landscape Of The Cleveland, Ohio Area, Rebecca M. Rashleigh, Robert A. Krebs, Harry Van Keulen
Population Structure Of Coyote (Canis Latrans) In The Urban Landscape Of The Cleveland, Ohio Area, Rebecca M. Rashleigh, Robert A. Krebs, Harry Van Keulen
Biological, Geological, and Environmental Faculty Publications
To obtain information on the population structure of coyote (Canis latrans) in an urban setting, a non-invasive genetic sampling technique was applied that consisted of DNA isolation from scat collected around the Cleveland metropolitan area. Muscle tissue was provided from two other coyotes. Amplifying the mitochondrial D-loop or control region produced 33 haplotypes from just 57 coyote sequences and two additional dog sequences from putative coyote-dog hybrids. The mitochondrial DNA genetic diversity in the Cleveland area was high, π 0.02, and composed of six distinct haplotype lineages. In addition, Fst values ranged from 0.07 between collections east and west of …
Roosting Ecology Of Rafinesque's Big-Eared Bat, Corynorhinus Rafinesquii, In Southeastern Mississippi, Austin Webb Trousdale Iii
Roosting Ecology Of Rafinesque's Big-Eared Bat, Corynorhinus Rafinesquii, In Southeastern Mississippi, Austin Webb Trousdale Iii
Dissertations
Rafinesque's big-eared bat, Corynorhinus rafinesquii, is considered rare and/or declining throughout its range. Concrete bridges are potentially important roosts for C. rafinesquii, especially in the Gulf Coastal Plain where the species' natural roosts (caves and large hollow trees) are inherently scarce. Successful efforts to monitor and conserve this species must account for its movements among multiple roosts and determine the duration of its roost use (including bridges) at different temporal scales. Therefore, I investigated roosting ecology of C. rafinesquii from 2000-2005 within a mixed hardwood-pine (Pinus spp.) system in southeastern Mississippi. I conducted surveys of concrete bridges to determine phenological …
What Do Students Have To Say About Ecology And Evolution? Using Podcasting To Apply Integrative Biology Themes Across The Tree Of Life, Amy M. Treonis, Malcolm Hill, Theresa Dolson, Sue Mcginnis, Elizabeth Miles
What Do Students Have To Say About Ecology And Evolution? Using Podcasting To Apply Integrative Biology Themes Across The Tree Of Life, Amy M. Treonis, Malcolm Hill, Theresa Dolson, Sue Mcginnis, Elizabeth Miles
Biology Faculty Publications
We describe a versatile podcasting assignment that requires students to (i) review primary and secondary literature relating to an assigned organism with the goal of identifying the main features of its ecology and evolution, (ii) prepare an enhanced podcast about their organism, and (iii) critique peer podcasts. The goal of this assignment is for each student to gain a fuller appreciation for and understanding of biological diversity. This assignment will enhance students' research, technology, and communication skills while reinforcing the main themes of integrative biology.

A Kinetic Model For Growth And Biosynthesis Of Medium-Chain-Length Poly-(3-Hydroxyalkanoates) In Pseudomonas Putida, Irene Tan Kit Ping
A Kinetic Model For Growth And Biosynthesis Of Medium-Chain-Length Poly-(3-Hydroxyalkanoates) In Pseudomonas Putida, Irene Tan Kit Ping
Irene Tan Kit Ping
A kinetic model is presented giving a mathematical description of batch culture of Pseudomonas putida PGA1 grown using saponified palm kernel oil as carbon source and ammonium as the limiting nutrient. The growth of the micro-organism is well-described using. Tessier-type model which takes into account the inhibitory effect of ammonium at high concentrations. The ammonium consumption rate by the cells is related ill proportion to the rate of growth. The intracellular production of medium-chain-length poly(3-hydroxyalkanoates) (PHA(MCL)) by P. putida PGA1 cells is reasonably modeled by the modified Luedeking-Piret kinetics, which incorporate a function of product Synthesis inhibition (or reduction) by …

Out Of South America: Multiple Origins Of Non-Native Apple Snails In Asia, Kenneth Hayes
Out Of South America: Multiple Origins Of Non-Native Apple Snails In Asia, Kenneth Hayes
Department of Biology Faculty Publications
Apple snails (Ampullariidae: Pomacea) native to the New World have become agricultural and environmental pests widely in southern and eastern Asia since their introduction in about 1980. Although their impacts have been extensively documented, considerable confusion persists regarding their identities and geographical origins. Efforts to resolve the confusion have suffered from inadequate taxonomic and geographical sampling from both native and introduced ranges. Using phylogenetic and genealogical methods, we analysed 610–655 bp of cytochrome c oxidase subunit I DNA sequences from 783 apple snails from 164 Asian locations and 57 native South American locations. In Asia, we found four species of …
Is The Amphibian Tree Of Life Really Fatally Flawed?, Darrel R. Frost, Taran Grant, Julian Faivovich, Raoul H. Bain, Alexander Haas, Celio F.B. Haddad, Rafael O. De Sá, Et Al.

Biology Faculty Publications
Wiens (2007, Q. Rev. Biol. 82, 55–56) recently published a severe critique of Frost et al.'s (2006, Bull. Am. Mus. Nat. Hist. 297, 1–370) monographic study of amphibian systematics, concluding that it is “a disaster” and recommending that readers “simply ignore this study”. Beyond the hyperbole, Wiens raised four general objections that he regarded as “fatal flaws”: (1) the sampling design was insufficient for the generic changes made and taxonomic changes were made without including all type species; (2) the nuclear gene most commonly used in amphibian phylogenetics, RAG-1, was not included, nor were the morphological characters that had justified …
