Impacts Of The Mycotoxin Zearalenone On Growth And Photosynthetic Responses In Laboratory Populations Of Freshwater Macrophytes (Lemna Minor) And Microalgae (Pseudokirchneriella Subcapitata)., Ej Eagles, R Benstead, S Macdonald, R Handy, Th Hutchinson Jan 2019

Impacts Of The Mycotoxin Zearalenone On Growth And Photosynthetic Responses In Laboratory Populations Of Freshwater Macrophytes (Lemna Minor) And Microalgae (Pseudokirchneriella Subcapitata)., Ej Eagles, R Benstead, S Macdonald, R Handy, Th Hutchinson

School of Biological and Marine Sciences

Mycotoxins are an important class of chemicals of emerging concern, recently detected in aquatic environments, potentially reflecting the influence of fungicide resistance and climatic factors on fungal diseases in agricultural crops. Zearalenone (ZON) is a mycotoxin formed by Fusarium spp. and is known for its biological activity in animal tissues; both in vitro and in vivo. ZON has been reported in US and Polish surface waters at 0.7 - 96 ng/L, with agricultural run-off and wastewater treatment plants being the likely sources of mycotoxins. As some mycotoxins can induce phytotoxicity, laboratory studies were conducted to evaluate the toxicity of ZON …

Bioavailability And Effects Of Microplastics On Marine Zooplankton: A Review., Zara L.R. Botterell, Nicola Beaumont, Tarquin Dorrington, Michael Steinke, Richard C. Thompson, Penelope K. Lindeque

School of Biological and Marine Sciences

Microplastics are abundant and widespread in the marine environment. They are a contaminant of global environmental and economic concern. Due to their small size a wide range of marine species, including zooplankton can ingest them. Research has shown that microplastics are readily ingested by several zooplankton taxa, with associated negative impacts on biological processes. Zooplankton is a crucial food source for many secondary consumers, consequently this represents a route whereby microplastic could enter the food web and transfer up the trophic levels. In this review we aim to: 1) evaluate the current knowledge base regarding microplastic ingestion by zooplankton in …

Patchiness In Habitat Distribution Can Enhance Biological Diversity Of Coastal Engineering Structures, Eva Cacabelos, Richard C. Thompson, Afonso C.L. Prestes, José Manuel N. Azevedo, Ana I. Neto, Gustavo M. Martins

School of Biological and Marine Sciences

© 2018 John Wiley & Sons, Ltd. Urbanization of coastal habitats is increasing worldwide. However, most man-made structures are poor surrogates for the habitats they replace and can strongly impact the diversity and functioning of coastal habitats. The value of coastal engineering can be enhanced by the provision of microhabitats that facilitate colonization by marine life. One step forward is moved in this research by combining species coexistence theory, resource patchiness and applied ecology in order to find ways that maximize the biological diversity of coastal defence structures. Featureless areas of a seawall were modified by the addition of microhabitats …

A Catchment-Scale Perspective Of Plastic Pollution, Fredric M. Windsor, Isabelle Durance, Alice A. Horton, Richard C. Thompson, Charles R. Tyler, Steve J. Ormerod Jan 2019

A Catchment-Scale Perspective Of Plastic Pollution, Fredric M. Windsor, Isabelle Durance, Alice A. Horton, Richard C. Thompson, Charles R. Tyler, Steve J. Ormerod

School of Biological and Marine Sciences

Plastic pollution is distributed across the globe, but compared with marine environments, there is only rudimentary understanding of the distribution and effects of plastics in other ecosystems. Here, we review the transport and effects of plastics across terrestrial, freshwater and marine environments. We focus on hydrological catchments as well-defined landscape units that provide an integrating scale at which plastic pollution can be investigated and managed. Diverse processes are responsible for the observed ubiquity of plastic pollution, but sources, fluxes and sinks in river catchments are poorly quantified. Early indications are that rivers are hotspots of plastic pollution, supporting some of …

Oscillations in the Earth’s temperature and the subsequent retreating and advancing of ice-sheets around the polar regions are thought to have played an important role in shaping the distribution and genetic structuring of contemporary high-latitude populations. After the Last Glacial Maximum (LGM), retreating of the ice-sheets would have enabled early colonizers to rapidly occupy suitable niches to the exclusion of other conspecifics, thereby reducing genetic diversity at the leading-edge. Bottlenose dolphins (genus Tursiops) form distinct coastal and pelagic ecotypes, with finer-scale genetic structuring observed within each ecotype. We reconstruct the postglacial colonization of the Northeast Atlantic (NEA) by bottlenose dolphins …

Gravel Beach Cross- And Alongshore Response To An Extreme Event: Beach Length And Headland Proximity Controls, Rj Mccarroll, G Masselink, M Wiggins, Tim Scott, O Billson, D Conley Jan 2019

Gravel Beach Cross- And Alongshore Response To An Extreme Event: Beach Length And Headland Proximity Controls, Rj Mccarroll, G Masselink, M Wiggins, Tim Scott, O Billson, D Conley

School of Biological and Marine Sciences

Gravel beach morphologic change is a function of combined cross- and alongshore transport. At present, numerical methods deal with these processes separately. We present observations from Start Bay, UK, of extreme storm response and recovery, across five gravel subembayments (lengths 250 m to 5 km). An easterly storm sequence in Feb-Mar 2018 forced massive alongshore transport (rotation and headland bypassing) and cross-shore transport including erosion of the barrier, destruction of barrier-crest roads, and distribution of material offshore. We demonstrate that profile response is a function of embayment length and headland proximity, such that: (i) pocket embayments (~250 m) experience a …

Changes In The Biochemical And Nutrient Composition Of Seafood Due To Ocean Acidification And Warming, A. J. Lemasson, J. M. Hall-Spencer, V. Kuri, A. M. Knights

School of Biological and Marine Sciences

Ocean acidification and warming may threaten future seafood production, safety and quality by negatively impacting the fitness of marine species. Identifying changes in nutritional quality, as well as species most at risk, is crucial if societies are to secure food production. Here, changes in the biochemical composition and nutritional properties of the commercially valuable oysters, Magallana gigas and Ostrea edulis, were evaluated following a 12-week exposure to six ocean acidification and warming scenarios that were designed to reflect the temperature (+3 °C above ambient) and atmospheric pCO 2 conditions (increase of 350–600 ppm) predicted for the mid-to end-of-century. Results suggest …

Removal Of Intertidal Grazers By Human Harvesting Leads To Alteration Of Species Interactions, Community Structure And Resilience To Climate Change, Ana Chaverra, Evie Wieters, Andy Foggo, Antony M. Knights Jan 2019

Removal Of Intertidal Grazers By Human Harvesting Leads To Alteration Of Species Interactions, Community Structure And Resilience To Climate Change, Ana Chaverra, Evie Wieters, Andy Foggo, Antony M. Knights

School of Biological and Marine Sciences

Extreme fluctuations in abiotic conditions can induce a biological stress response (e.g. bleaching) detrimental to an organism's health. In some instances, organisms can recover if conditions are alleviated, such as through co-occurrence with other species that confer protection. Biodiverse, multitrophic communities are increasingly recognised as important promoters of species persistence and resilience under environmental change. On intertidal shores, the role of grazers as top-down determinants of algal community structure is well recognised. Similarly, the harvesting of grazers for human consumption is increasingly prevalent with potential to greatly alter the community dynamics. Here, we assess how differences in harvesting pressure of …

Observations Of Infragravity Dominance In The Swash Zone Of A Steep Gravel Beach, O Billson, P Russell, M Davidson, M Wiggins, Jak Mccarroll, T Poate, N Leonardi

School of Biological and Marine Sciences

Observations of the depth integrated and time averaged sediment transport on a mixed sand and gravel (MSG) beach are presented and analysed to examine the performance of a new portable streamer trap. Measurement of the longshore sediment transport rate in the surf zone remains one of the great challenges in coastal engineering and coastal sciences. Sediment traps for sand beaches have proven useful in the past, but are not suitable for MSG beaches. This paper describes a portable depth-integrated streamer trap designed to measure the depthintegrated combined bed load and suspended longshore sediment transport on MSG beaches. The device consists …

Gender Incongruence In Children, Adolescents And Adults, Susan Bewley, Damian Clifford, Margaret Mccartney, Richard Byng Jan 2019

Gender Incongruence In Children, Adolescents And Adults, Susan Bewley, Damian Clifford, Margaret Mccartney, Richard Byng

Peninsula Medical School

More individuals are requesting medical assistance for gender uncertainty or dysphoria and provision of adult NHS gender identity services (GIS) is changing. Despite minimal medical input to polarised debates, several issues are potentially concerning: reports of poor care; rapid rises in referrals of children and young people to GIS; public conflation of biological sex with socially influenced gender roles; and extensive uncertainty in the evidence base to guide practice. Medical practice should happen within robust human rights frameworks where individual patients always have their concerns heard. Generalists, with expertise in whole-person care, handling uncertainty and complexity, have a key role …

Modeling Cell Line-Specific Recruitment Of Signaling Proteins To The Insulin-Like Growth Factor 1 Receptor, Keesha E. Erickson, Dipak Barua, For Full List Of Authors, See Publisher's Website.

Chemical and Biochemical Engineering Faculty Research & Creative Works

Receptor tyrosine kinases (RTKs) typically contain multiple autophosphorylation sites in their cytoplasmic domains. Once activated, these autophosphorylation sites can recruit downstream signaling proteins containing Src homology 2 (SH2) and phosphotyrosine-binding (PTB) domains, which recognize phosphotyrosine-containing short linear motifs (SLiMs). These domains and SLiMs have polyspecific or promiscuous binding activities. Thus, multiple signaling proteins may compete for binding to a common SLiM and vice versa. To investigate the effects of competition on RTK signaling, we used a rule-based modeling approach to develop and analyze models for ligand-induced recruitment of SH2/PTB domain-containing proteins to autophosphorylation sites in the insulin-like growth factor 1 …
