Biochemical plasticity in seaweeds: assessment and optimisation of high value compounds
Schmid, Matthias (2016-02-16)Macroalgae are important primary producers and habitat forming organisms of the marine coastal zone. In response to different environmental parameters, the chemical composition of macroalage can change as an acclimation ... -
Developing an integrated approach to seaweed resource assessment
Rossiter, Thomas (NUI Galway, 2020-09-01)Increasing interest in the sustainable management of Irish macroalgal resources requires the development of a cost-effective and efficient methodology for quantifying the distribution of key species. Remote sensing provides ... -
Ecophysiological studies of selected macro- and microalgae: production of organic compounds and climate change interactions
Zacharias, Merry (2012-03-29)This study focused on algal ecophysiological and chemical responses of marine algae to environmental impacts, in particular, light including UV radiation, temperature and nutrients. Marine algae influence climate by affecting ... -
Impacts of natural and induced abiotic factors on phlorotannins in brown algae
Kirke, Dara Ann (2018-02-22)Phlorotannins are a group of highly bioactive marine polyphenols found exclusively in brown algae. They play multiple ecological roles in algae inhabiting stressful environments and, as a result, their natural concentrations ... -
Irish seagrass ecology and habitat mapping in the context of climate change
Beca-Carretero, Pedro (NUI Galway, 2019-01-28)Seagrasses play an important ecological role worldwide, providing numerous ecosystems services. Zostera marina is a dominant meadow-forming seagrass in temperate regions in the northern hemisphere, including Irish coasts. ... -
Voltammetric Characterization of Macroalgae-Exuded Organic Ligands in Response to Metal Exposure
Murray, Hollydawn (2013-09-30)Trace metal availability, and hence toxicity, is largely dependent on metal speciation. It is well established that in seawater complexation by organic ligands dominates the speciation of most metals including Cd, Cu, Pb, ...
