Increasing The Depth Of Current Understanding: Sensitivity Testing Of Deep-Sea Larval Dispersal Models For Ecologists, Rebecca E. Ross, W. Alex M. Nimmo-Smith, Kerry L. Howell
Increasing The Depth Of Current Understanding: Sensitivity Testing Of Deep-Sea Larval Dispersal Models For Ecologists, Rebecca E. Ross, W. Alex M. Nimmo-Smith, Kerry L. Howell
School of Biological and Marine Sciences
Larval dispersal is an important ecological process of great interest to conservation and the establishment of marine protected areas. Increasing numbers of studies are turning to biophysical models to simulate dispersal patterns, including in the deep-sea, but for many ecologists unassisted by a physical oceanographer, a model can present as a black box. Sensitivity testing offers a means to test the models' abilities and limitations and is a starting point for all modelling efforts. The aim of this study is to illustrate a sensitivity testing process for the unassisted ecologist, through a deep-sea case study example, and demonstrate how sensitivity …

From Medicine To Butterflies And Back Again, C Parmesan
School of Biological and Marine Sciences
My research focuses on the current impacts of climate change on wildlife, from field-based work on butterflies to synthetic analyses of global impacts on a broad range of species across terrestrial and marine biomes. I work actively with governmental agencies and NGOs to help develop conservation assessment and planning tools aimed at preserving biodiversity in the face of climate change.

Capture Technique And Fish Personality: Angling Targets Timid Bluegill Sunfish,Lepomis Macrochirus, Alexander D.M. Wilson, Thomas R. Binder, Keegan P. Mcgrath, Steven J. Cooke, Jean Guy J. Godin
School of Biological and Marine Sciences
Size-selective harvesting associated with commercial and recreational fishing practices has been shown to alter life history traits through a phenomenon known as fishing-induced evolution. This phenomenon may be a result of selection pathways targeting life-history traits directly or indirectly through correlations with behavioral traits. Here, we report on the relationship between individual differences in behavior and capture technique (beach seining versus angling) in wild-caught juvenile bluegill sunfish ( Lepomis macrochirus ). Both fish caught by using a seine net (seined) and fish caught by using a lure (angled) were individually tested under standardized laboratory conditions for their boldness, water-column use, …

Climate Change And The Green Energy Paradox: The Consequences For Twaite Shad Alosa Fallax From The River Severn, U.K., Mw Aprahamian, Cd Aprahamian, Am Knights
Climate Change And The Green Energy Paradox: The Consequences For Twaite Shad Alosa Fallax From The River Severn, U.K., Mw Aprahamian, Cd Aprahamian, Am Knights
School of Biological and Marine Sciences
A stock–recruitment model with a temperature component was used to estimate the effect of an increase in temperature predicted by climate change projections on population persistence and distribution of twaite shad Alosa fallax. An increase of 1 and 2° C above the current mean summer (June to August) water temperature of 17·8° C was estimated to result in a three and six-fold increase in the population, respectively. Climate change is also predicted to result in an earlier commencement to their spawning migration into fresh water. The model was expanded to investigate the effect of any additional mortality that might arise …
Marine Plankton Phenology And Life History In A Changing Climate: Current Research And Future Directions, R Ji, M Edwards, Dl Mackas, Ja Runge, Ac Thomas
Marine Plankton Phenology And Life History In A Changing Climate: Current Research And Future Directions, R Ji, M Edwards, Dl Mackas, Ja Runge, Ac Thomas
School of Biological and Marine Sciences
Increasing availability and extent of biological ocean time series (from both in situ and satellite data) have helped reveal significant phenological variability of marine plankton. The extent to which the range of this variability is modified as a result of climate change is of obvious importance. Here we summarize recent research results on phenology of both phytoplankton and zooplankton. We suggest directions to better quantify and monitor future plankton phenology shifts, including (i) examining the main mode of expected future changes (ecological shifts in timing and spatial distribution to accommodate fixed environmental niches vs. evolutionary adaptation of timing controls to …

Water Bathing Alters The Speed–Accuracy Trade-Off Of Escape Flights In European Starlings, Bo Brilot, L Asher, M Bateson
Water Bathing Alters The Speed–Accuracy Trade-Off Of Escape Flights In European Starlings, Bo Brilot, L Asher, M Bateson
School of Biological and Marine Sciences
Birds of most species regularly bathe in water, but the function of this behaviour is unknown. We tested the hypothesis that water bathing is important in feather maintenance, and hence should enhance flight performance. We manipulated European starlings', Sturnus vulgaris, access to bathing water in a 2 × 2 design: birds were housed in aviaries either with or without water baths for a minimum of 3 days (long-term access) before being caught and placed in individual cages either with or without water baths for a further 24 h (short-term access). We subsequently assessed the speed and accuracy of escape flights …
Scientific Divers Quantify First Known Outbreaks Of Cold-Water Coral Disease, J Hall-Spencer, C Munn, K Hiscock
Scientific Divers Quantify First Known Outbreaks Of Cold-Water Coral Disease, J Hall-Spencer, C Munn, K Hiscock
School of Biological and Marine Sciences
Coral diseases are widely reported in the tropics but the first incidence of cold-water coral disease was not noted until 2002 when divers recorded an outbreak at 10-28 m depth off Lundy in a NE Atlantic marine protected area. The seafan Eunicella verrucosa exhibited coenchyme necrosis and subsequent diving surveys of >600 colonies at 13 sites since revealed that disease outbreaks were widespread in SW England to depths of 50 m from 2003-2008, possibly caused by infection by Vibrio bacteria at high temperatures.

Consistency In Context‐Specific Measures Of Shyness And Boldness In Rainbow Trout, Oncorhynchus Mykiss, Alexander D.M. Wilson, E. D. Stevens
Consistency In Context‐Specific Measures Of Shyness And Boldness In Rainbow Trout, Oncorhynchus Mykiss, Alexander D.M. Wilson, E. D. Stevens
School of Biological and Marine Sciences
AbstractShyness and boldness has been considered a fundamental axis of human behavioural variation. At the extreme ends of this behavioural continuum subjects vary from being bold and assertive to shy and timid. Analogous patterns of individual variation have been noted in a number of species including fish. There has been debate on the nature of this continuum as to whether it depends on context. That is, whether it is domain‐general (as in humans), or context‐specific. The purpose of our study was to test if shyness and boldness depends on context in rainbow trout, Oncorhynchus mykiss and to this end we …

Effects Of Towed Demersal Fishing Gear On Biogenic Sediments: A 5-Year-Study, Jm Hall-Spencer
Effects Of Towed Demersal Fishing Gear On Biogenic Sediments: A 5-Year-Study, Jm Hall-Spencer
School of Biological and Marine Sciences
Experimental scallop fishing was carried out using towed commercial dredges on sediments deposited by unattached coralline algae in order to quantify their sensitivity to damage from current fishing practices. These biogenic sediments are patchily distributed in European coastal waters (to -30 m depth around the UK and to -120 m in the Mediterranean) and are of international conservation importance. This paper describes the short and long-term effects of scallop dredging on previously unfished and fished areas of biogenic algal sediment in SW Scotland. Sediment cores taken biannually from 1994-99 were used to assess live coralline abundance on marked test and …
