Introduction
Andrew Want currently works at the University of Hull's Energy and Environment Institute. Andrew is a marine ecologist pursuing a multi-faceted research approach to uncover mechanisms that underpin marine population responses to environmental changes created as the transition to decarbonise energy generation accelerates. This includes close partnership with the European Marine Energy Centre exploring the impacts of marine growth in the offshore renewable energy industry.

A novel system was developed to deploy settlement panels to monitor biofouling growth in situ and evaluate antifouling coatings at depths representative of operational conditions of full-scale marine renewable energy devices. Biofouling loading, species diversity, and succession were assessed at depths ranging from 25-40 m at four tests sites in Or...
As part of ongoing commitments to produce electricity from renewable energy sources in Scotland, Orkney waters have been targeted for potential large-scale deployment of wave and tidal energy converting devices. Orkney has a well-developed infrastructure supporting the marine energy industry; recently enhanced by the construction of additional pier...
In the North-east (NE) Atlantic, most intertidal fucoids and warm-temperate kelps show unique low-latitude gene pools matching long-term climatic refugia. For cold-temperate kelps data are scarcer despite their unique cultural, ecological and economic significance. Here we test whether the amphi-Atlantic range of Laminaria digitata is derived from...
Temperature extremes are predicted to intensify with climate change. These extremes are rapidly emerging as a powerful driver of species distributional changes with the capacity to disrupt the functioning and provision of services of entire ecosystems, particularly when they challenge ecosystem engineers. The subsequent search for a robust framewor...
The biofouling of submerged anthropogenic surfaces and factors that contribute to the spread of non-indigenous species (NIS)
have both received substantial attention from researchers, regulators and the private sector focused on understanding their
economic, social and environmental consequences. This work has informed the development and impleme...
Wave energy has the potential to contribute in the transition to decarbonized electricity generation. Extracting wave energy might be expected to have ecological impacts on rocky shore intertidal communities where exposure is one of the most important factors determining species structure and composition. With global climatic change, coastal exposu...
Amphiboreal taxa are often composed of vicariant phylogroups and species complexes whose divergence and phylogeographic affinities reflect a shared history of chronic isolation and episodic trans-Arctic dispersal. Ecological filters and shifting selective pressures may also promote selective sweeps, niche shifts and ecological speciation during col...
Marine habitats are being targeted for the extraction of offshore renewable energy (ORE) as part of the drive to decarbonise electricity generation. Unmanaged biofouling impacts ORE devices and infrastructure by elevating drag forces, increasing weight, and accelerating corrosion, leading to decreased performance and survivability, and extending co...
The spread of the brown seaweed Sargassum muticum is one of the best documented invasions of a non-native marine species. Observation of a potentially established population of S. muticum in the Orkney Islands archipelago, located off the northern coast of Scotland, was reported by recreational snorkellers in 2019 and 2020. The present study summar...
A new record of an individual of the invasive sea squirt, Styela clava , is reported from Scapa Flow in Orkney, Scotland. This represents a 1.54° latitudinal extension (168 km) from the previous northern-most record in UK waters. Diver surveys of hard substrates in the immediate area, part of local biosecurity protocols, did not find any additional...
The Scottish Wildlife Trust commissioned this desk-based natural capital assessment of the Orkney Islands Scottish Marine Region to identify the type, location, condition, importance and vulnerabilities of natural capital assets and associated ecosystem services that are of value to the Orkney community and potentially wider communities.
Water movements define some of the most important ecological factors determining the distribution of organisms in marine environments. This is true both at large spatial scales, where ecological connectivity and trophic coupling are defined by circulation patterns and vertical mixing structure, and at the much smaller scales at which individual org...
This study provides an audit of the potential blue carbon resources present in the coastal waters around Orkney, bounded by the 12 nautical mile limit and including the Loch of Stenness brackish water lagoon. This report builds on previous work in which blue carbon stocks in Marine Protected Areas in Scottish waters were estimated from i) contribut...
Extensive marine growth on man-made structures in the ocean is commonplace, yet there has been limited discussion about the potential implications of marine growth for the wave and tidal energy industry. In response, the Environmental Interactions of Marine Renewables (EIMR) Biofouling Expert Workshop was convened. Discussions involved participants...
Background
Loch Laxford SAC was established to afford protection for the marine features ‘large shallow
inlets and bays’ and 'reefs'. The aim of the current 2015 study was to carry out site condition
monitoring (SCM) of the designated features of the SAC, in order to identify any deterioration
in the condition of the features and to form a judgemen...
The Loch Laxford SAC was established to afford protection for the marine features 'large shallow inlets and bays' and 'reefs'. The aim of the current 2015 study was to carry out site condition monitoring (SCM) of the designated features of the SAC, in order form a judgement on their current condition. The 2015 SCM work largely took the form of a dr...
As part of the UK government's objective to deliver an increasing proportion of electricity from renewable sources, West Mainland, Orkney, is at the forefront of the development of wave-energy extraction devices. Exposure to wave energy plays a dominant role in shaping the Orkney landscape and determining the ecological community, but little is kno...
Many countries now recognise the need for mitigation of climate change induced by human activities and have incorporated renewable energy resources within their energy policy. There are extensive resources of renewable energy within the marine environment and increasing interest in extracting energy from locations with either large tidal range, rap...
The goal of this study was to determine the role of the pontine lateral parabrachial nucleus (LPBN) in the compensatory responses to blood loss. Conscious unrestrained rats with complete, partial, or sham bilateral ibotenic acid lesions of the LPBN were subjected to a hypotensive 16-ml/kg blood withdrawal via arterial catheter. Complete lesions (LP...
To study the changes in neuroautonomic regulation of heart rate and the effects of N(G)-nitro-L-arginine methyl ester (L-NAME), a competitive inhibitor of nitric oxide synthase, on efferent sympathetic cardiac activity and blood pressure during hypovolemic shock. Hypotension during hypovolemic shock may be attributable, in part, to the failure of n...
The goal of this study was to determine the role of the parvicellular component of the paraventricular hypothalamic nucleus (PVH) in the compensatory responses to blood loss. Male Sprague-Dawley rats were prepared with bilateral ibotenate lesions of the parvicellular PVH (PVHx; n = 5) or with sham lesions (Sham; n = 8). After >10 days recovery, hem...
1. The paraventricular hypothalamic nucleus (PVH) is a complex structure with both neuroendocrine and autonomic functions. It is a major source of vasopressin and the primary source of corticotropin-releasing factor. In addition, parvicellular PVH neurons have reciprocal connections with brain-stem autonomic centres and directly innervate sympathet...
The goal of this study was to determine the role of the pontine LPBN in the compensatory responses to blood loss (HEM). Male SpragueDawley rats were prepared with LPBN lesions by bilateral stereotaxic 400500 nl injections of 10 ug/ul ibotenic acid. After >10 days recovery, HEM was performed by gradual withdrawal of 16 ml/kg blood over 34 min, via a...
