Research Overview
I study the relationship between pollutant speciation and toxicity. This considers the fate and transformation of environmental pollutants. This is done through the use of analytical chemical tools to study organism responses to pollutants. I am also enthused by the application and comparison of ecotoxicity assays to various environmental sample. I also use general research skills in soil microbiology and biochemistry. Specific areas of interest are:
- Fate of inorganic/ organic pollutants in the environment
- Development of bioassays to assess environmental toxicity
- Chemical and biological techniques for environmental restoration
- Soil genesis and classification and linkage to soil biology

Current Research
Current Research Group
The current research group has several strands. Mostly the focus is on process level soil microbiology as a response to perturbations- mainly pollution. Biosensors are widely used to quantify and better understand these mpacts and to relate to the aspects of bioavailability. To an extent these enable sustainable solutions to be developed and bespoke risk assessment to be measured.
If you are interested in joining the group then have a think about the work that the current group and recently completed members have contributed.
Dr. Lenka Mbadugha complements the research team with her expertise in pollution monitoring, biosensor development and soil carbon dynamics.
Rosie Boyko has completed her PhD studying the link between soil pH management and sward quality with reference to Scotland and food security. Thnayan Alonaizi is studying soil-based enzymes to devise recolonisation techniques in impacted soils. This bioaugmentation work is a new twist of remediation work with hydrocarbons that we have done in the past. He is also transplanting functional biomes back into soils. Onome Omovie-Stephen is applying techniques for carbon fractionation to contrastingly managed soils to try and develop techniques to better sequester soil carbon. The great challenge is to understand carbon partitioning and links to function and availability.
Sapar Dossanov successfully defended his thesis: integrated approaches of risk and hazard assessment in current and historic metal mines. This work was further enhanced by Sandra Arroyo Sanchez who has upskilled the use of SEM and applied the risk assessment/ human exposure/ model approaches to Mexico. She aslo successfully defended her PhD.
Alexander Kani completed his work in bioleaching of metal wastes as a process for elemental recovery in a sustainable manner. The focus was on critical elements and we have widened the scope from mine wastes to other matrices and are developing resin based systems for capture.
Christoph Gade studied elemental cycling of mercury with a focus on marine sources and fate but extended this to wider geochemical concepts. The driver here is to truth test models that have been established making use of specific analytical approaches. He has also established some effective and innovative ecotoxicological testing.

Soil and vegetation parameters from re-visitation of fertilisation experiment at Ny-Alesund, Svalbard
In 1991 a nitrogen x phosphorus fertilisation experiment on dwarf shrub tundra close to Ny-Alesund, Svalbard was established. Treatments (0, 10, 50 kg N ha-1 yr-1; 0, 5 kg P ha-1 yr-1) were applied to Cassiope heath for 3 years and Dryas heath for 8 years. In 2011 the experiment was revisited to investigate the persistence of effects of fertilisation on species composition, vegetation nutrient status and ecosystem carbon stocks. The whole experiment has been led by Dr Sarah Woodin and colleagues, University of Aberdeen. The 2011 study, for which data are provided, was undertaken by Dr Lorna Street.- DOI

Effects of prior contest experience and contest outcome on female reproductive decisions and offspring fitness
Data from: Effects of prior contest experience and contest outcome on female reproductive decisions and offspring fitness Winning or losing a prior contest can influence the outcome of future contests, but it might also alter subsequent reproductive decisions. For example, losers may increase their investment in the current breeding attempt if losing a contest indicates limited prospects for future breeding. Using the burying beetle Nicrophorus vespilloides, we tested whether females adjust their prehatching and posthatching reproductive effort after winning or losing a contest with a same-sex conspecific. Burying beetles breed on carcasses of small vertebrates for which there is fierce intrasexual competition. We found no evidence that winning or losing a contest influenced reproductive investment decisions in this species. Instead, we show that a female's prior contest experience (regardless of its outcome) influenced the amount of posthatching care provided, with downstream consequences for the female's reproductive output; both winners and losers spent more time provisioning food to their offspring and produced larger broods than females with no contest experience. We discuss the wider implications of our findings and present a conceptual model linking contest-mediated adjustments in parental investment to population-level processes. We propose that the frequency of intraspecific contests could both influence and be influenced by population dynamics in species where contest experience influences the size and/or number of offspring produced.- DOI

Maternal effects alter the severity of inbreeding depression in the offspring
Data from: Maternal effects alter the severity of inbreeding depression in the offspring A maternal effect is a causal influence of the maternal phenotype on the offspring phenotype over and above any direct effects of genes. There is abundant evidence that maternal effects can have a major impact on offspring fitness. Yet, no previous study has investigated the potential role of maternal effects in influencing the severity of inbreeding depression in the offspring. Inbreeding depression is a reduction in the fitness of inbred offspring relative to outbred offspring. Here, we tested whether maternal effects due to body size alter the magnitude of inbreeding depression in the burying beetle Nicrophorus vespilloides. We found that inbreeding depression in larval survival was more severe for offspring of large females than offspring of small females. This might be due to differences in how small and large females invest in an inbred brood because of their different prospects for future breeding opportunities. To our knowledge, this is the first evidence for a causal effect of the maternal phenotype on the severity of inbreeding depression in the offspring. In natural populations that are subject to inbreeding, maternal effects may drive variation in inbreeding depression and therefore contribute to variation in the strength and direction of selection for inbreeding avoidance.- DOI

Data and R code for What you see is where you go: visibility influences movement decisions of a forest bird navigating a 3D structured matrix
Animal spatial behaviour is often presumed to reflect responses to visual cues. However, inference of behaviour in relation to the environment is challenged by the lack of objective methods to identify the information that effectively is available to an animal from a given location. In general, animals are assumed to have unconstrained information on the environment within a detection circle of a certain radius (the perceptual range; PR). However, visual cues are only available up to the first physical obstruction within an animal’s PR, making information availability a function of an animal’s location within the physical environment (the effective visual perceptual range; EVPR). By using LiDAR data and viewshed analysis, we model forest birds’ EVPRs at each step along a movement path. We found that the EVPR was on average 0.063% that of an unconstrained PR and, by applying a step-selection analysis, that individuals are 1.57 times more likely to move to a tree within their EVPR than to an equivalent tree outside it. This demonstrates that behavioural choices can be substantially impacted by the characteristics of an individual’s EVPR and highlights that inferences made from movement data may be improved by accounting for the EVPR.- DOI

Data from: Mutation accumulation and the formation of range limits
The dynamics of range formation are important for understanding and predicting species distributions. Here, we focus on a process that has thus far been overlooked in the context of range formation; the accumulation of mutation load. We find that mutation accumulation severely reduces the extent of a range across an environmental gradient, especially when dispersal is limited, growth rate is low and mutations are of intermediate deleterious effect. Our results illustrate the important role deleterious mutations can play in range formation. We highlight this as a necessary focus for further work, noting particularly the potentially conflicting effects dispersal may have in reducing mutation load and simultaneously increasing migration load in marginal populations.- DOI

Data from: Sex differences in risk perception in deep-diving bottlenose dolphins leads to decreased foraging efficiency when exposed to human disturbance
1. Individuals make behavioural decisions by weighing potential advantages and costs (e.g. increased food intake vs. increased risk of predation). When animals change their activities in response to a perceived threat, their energetic input may decline. Marine ecotourism, including whale and dolphin watching, is growing globally and cetaceans perceive interactions with tour vessels as a form of risk. Observable behavioural changes need to be linked to bioenergetic effects to determine the potential population consequences of this disturbance. 2. We developed a theoretical optimal dive model for bottlenose dolphins under three potential types of perceived risk resulting from human interactions at the surface (decreasing instantaneous risk, increasing instantaneous risk and no risk). We compared the predictions of these theoretical models to observed dive cycles of foraging male and female dolphins in the presence and absence of tour vessels. We used mixture models to classify dive types and mixed effects models to analyse changes in the interbreath interval of surface and bottom dives and the frequency of estimated bottom dives. 3. Males significantly increased bottom time and performed fewer bottom dives when boats were present, matching predictions of our theoretical model for perceived decreasing instantaneous risk. In contrast, females significantly decreased bottom times and increased the frequency of bottom dives, matching predictions from the model for perceived increasing instantaneous risk. Therefore, our empirical results suggest differences in the perception of risk between sexes. 4. Synthesis and applications. By comparing theoretical predictions with observed dive data, our study suggests that boat interactions during foraging can cause decreased net energy gain over a foraging bout for both sexes, with females being more impacted. The population under study is currently listed as critically endangered. Understanding whether these predicted energetic impacts affect an individual's vital rates will provide a link to the population-level consequences of this disturbance. Previous analytical approaches have failed to capture the costs associated with disturbance during foraging, leading to management recommendations that only protect animals from increased energetic expenditure. We suggest that the current management scheme should be revised to include foraging areas in order to secure the energy intake of animals.- DOI

Data from: Taking movement data to new depths: Inferring prey availability and patch profitability from seabird foraging behavior
Detailed information acquired using tracking technology has the potential to provide accurate pictures of the types of movements and behaviors performed by animals. To date, such data have not been widely exploited to provide inferred information about the foraging habitat. We collected data using multiple sensors (GPS, time depth recorders, and accelerometers) from two species of diving seabirds, razorbills (Alca torda, N = 5, from Fair Isle, UK) and common guillemots (Uria aalge, N = 2 from Fair Isle and N = 2 from Colonsay, UK). We used a clustering algorithm to identify pursuit and catching events and the time spent pursuing and catching underwater, which we then used as indicators for inferring prey encounters throughout the water column and responses to changes in prey availability of the areas visited at two levels: individual dives and groups of dives. For each individual dive (N = 661 for guillemots, 6214 for razorbills), we modeled the number of pursuit and catching events, in relation to dive depth, duration, and type of dive performed (benthic vs. pelagic). For groups of dives (N = 58 for guillemots, 156 for razorbills), we modeled the total time spent pursuing and catching in relation to time spent underwater. Razorbills performed only pelagic dives, most likely exploiting prey available at shallow depths as indicated by the vertical distribution of pursuit and catching events. In contrast, guillemots were more flexible in their behavior, switching between benthic and pelagic dives. Capture attempt rates indicated that they were exploiting deep prey aggregations. The study highlights how novel analysis of movement data can give new insights into how animals exploit food patches, offering a unique opportunity to comprehend the behavioral ecology behind different movement patterns and understand how animals might respond to changes in prey distributions.- DOI

Data from: The Odonate Phenotypic Database, a new open data resource for comparative studies of an old insect order
We present The Odonate Phenotypic Database (OPD): an online data resource of dragonfly and damselfly phenotypes (Insecta: Odonata). Odonata is a relatively small insect order that currently consists of about 6400 species belonging to 32 families. The database consists of a variety of morphological, life-history and behavioral traits, and biogeographical information collected from literature sources. We see taxon-specific phenotypic databases from Odonata and other organismal groups as becoming an increasing valuable resource in comparative studies. Our database has phenotypic records for 1011 of all 6400 known odonate species. Methods The Odonate Phenotypic Database (OPD) is an online data resource of dragonfly and damselfly phenotypes (Insecta: Odonata). The database consists of multiple morphological, life-history and behavioral traits, and biogeographical information collected from literature sources. We see taxon-specific phenotypic databases from Odonata and other organismal groups as becoming an increasing valuable resource in comparative studies. The database is accessible at http://www.odonatephenotypicdatabase.org/, and a static version with an information file about the variables in the database is archived at Dryad.- DOI

Data from: Two decades of altered snow cover does not affect soil microbial ability to catabolize carbon compounds in an oceanic alpine heath
Snow strongly affects ecosystem functioning in alpine environments with potential carry-over effects outside of snow periods. However, it is unclear whether changes in snow cover affect microbial community functioning in summer. In a field experiment, we tested whether manipulation of snow cover affected the functional capabilities of the microbial community either directly, or indirectly through concomitant changes in the vegetation. While 23 years of differential snow depth and persistence fundamentally changed the vegetation composition, the microbial community's ability to catabolize a range of carbon compounds was not altered. Instead, soil moisture content was the key driver of carbon catabolism by the microbial community.- DOI

Data from: Mimicry and mitonuclear discordance in nudibranchs: new insights from exon capture phylogenomics
Phylogenetic inference and species delimitation can be challenging in taxonomic groups that have recently radiated and where introgression produces conflicting gene trees, especially when species delimitation has traditionally relied on mitochondrial data and colour pattern. Chromodoris, a genus of colourful and toxic nudibranch in the Indo-Pacific, has been shown to have extraordinary cryptic diversity and mimicry, and has recently radiated, ultimately complicating species delimitation. In these cases, additional genome-wide data can help improve phylogenetic resolution and provide important insights about evolutionary history. Here, we employ a transcriptome-based exon capture approach to resolve Chromodoris phylogeny with data from 2,925 exons and 1,630 genes, derived from 15 nudibranch transcriptomes. We show that some previously identified mimics instead show mitonuclear discordance, likely deriving from introgression or mitochondrial capture, but we confirm one ‘pure’ mimic in Western Australia. Sister-species relationships and species-level entities were recovered with high support in both concatenated Maximum Likelihood (ML) and summary coalescent phylogenies, but the ML topologies were highly variable while the coalescent topologies were consistent across datasets. Our work also demonstrates the broad phylogenetic utility of 149 genes that were previously identified from eupulmonate gastropods. This study is one of the first to i) demonstrate the efficacy of exon capture for recovering relationships among recently radiated invertebrate taxa, ii) employ genome-wide nuclear markers to test mimicry hypotheses in nudibranchs and iii) provide evidence for introgression and mitochondrial capture in nudibranchs.- DOI

Multigenerational exposure to elevated temperatures leads to a reduction in standard metabolic rate in the wild
1. In light of global climate change, there is a pressing need to understand and predict the capacity of populations to respond to rising temperatures. Metabolic rate is a key trait that is likely to influence the ability to cope with climate change. Yet, empirical and theoretical work on metabolic rate responses to temperature changes has so far produced mixed results and conflicting predictions. 2. Our study addresses this issue using a novel approach of comparing fish populations in geothermally warmed lakes and adjacent ambient-temperature lakes in Iceland. This unique ‘natural experiment’ provides repeated and independent examples of populations experiencing contrasting thermal environments for many generations over a small geographic scale, thereby avoiding the confounding factors associated with latitudinal or elevational comparisons. Using Icelandic sticklebacks from three warm and three cold habitats, we measured individual metabolic rates across a range of acclimation temperatures to obtain reaction norms for each population. 3. We found a general pattern for a lower standard metabolic rate in sticklebacks from warm habitats when measured at a common temperature, as predicted by Krogh’s rule. Metabolic rate differences between warm- and cold-habitat sticklebacks were more pronounced at more extreme acclimation temperatures, suggesting the release of cryptic genetic variation upon exposure to novel conditions, which can reveal hidden evolutionary potential. We also found a stronger divergence in metabolic rate between thermal habitats in allopatry than sympatry, indicating that gene flow may constrain physiological adaptation when dispersal between warm and cold habitats is possible. 4. In sum, our study suggests that fish may diverge toward a lower standard metabolic rate in a warming world, but this might depend on connectivity and gene flow between different thermal habitats.- DOI

Similar foraging behaviour but different habitat use between failed and successful breeding albatrosses
3rd World Seabird Conference 2021 Abstract: Breeding failure is expected to induce behavioural changes in central place foraging seabirds. Indeed, failed breeders do not have to regularly come back to their colony for reproductive duties and thus, they are not constrained anymore in their movements for the rest of the breeding season. Accordingly, they are expected to adjust their at-sea behaviour, travelling longer in distance and/or time to reach foraging grounds. They are also expected to use different foraging areas to decrease local intra-specific competition with successful breeders. However, so far, only few studies have investigated the effect of breeding failure on individual behaviour and distribution. In this study, we compared the at-sea behaviour and habitat use of successful and failed Indian yellow-nosed albatrosses nesting in Amsterdam Island, Southern Indian Ocean, during two chick-rearing periods. Failed breeders exhibited the same at-sea foraging behaviour, travelling as far and as long as successful breeders. They also spent the same amount of time on their nest between at-sea trips. Nevertheless, habitat models revealed a partial spatial segregation of failed breeders, which used specific foraging areas characterized by deeper and colder waters, in addition to the ones they shared with successful breeders. Our study stresses the importance of considering breeding failure when aiming at understanding the spatial distribution of individuals, especially in a conservation perspective.

Linking theory and data to forecast population dynamics of partially migratory seabird populations in the face of global change.
3rd World Seabird Conference 2021 Abstract: The effects of global change, including changes in seasonality and increased frequency and intensity of extreme events, might be expected to drive novel eco-evolutionary dynamics in seabird populations that are seasonally mobile. Identifying life-history traits, stages and locations that control the persistence and growth rates of seabird populations is crucial for conservation, but remains an open challenge. General theory and empirical data that incorporates dynamic variation in seasonal movement, and identifies fundamental principles of such systems, is still lacking. We devised full-annual-cycle models that capture key dimensions of demographic structure in a seasonally varying environment. First, we conceptualize movement through two variable vital rates: seasonal movement and its associated survival probability, and derive population growth rate and associated elasticities for stereotypical long-lived seabird species considering different levels of movement plasticity. Second, we evaluate the impacts of extreme climatic events in key life-history traits of a seasonally mobile metapopulation of European shags (Phalacrocorax aristotelis). We show that seasonal movement and its plasticity can substantially affect population persistence and growth rate, with effects comparable with survival or fecundity. Further, we quantify selection on key vital rates of migrants vs residents under extreme and benign conditions and explored its potential eco-evolutionary implications in the face of global change. Overall, we extend demographic and evolutionary theory and empirical studies by encompassing variable seasonal movement and revisiting its implications to understand and forecast open population dynamics under global change.

Reef effect of offshore structures on the occurrence and foraging activity of harbour porpoises
With increasing numbers of offshore structures to be decommissioned, a better understanding of their effect on marine predators is timely. There is some evidence that oil and gas platforms may attract marine mammals acting as artificial reefs. However, it is unclear whether different man-made structure designs have similar effects. Further, due to the lack of baseline data prior to installation, it is unknown whether artificial structures modify the diel patterns of occurrence and foraging behaviour of marine mammals. Here, we used passive acoustics to investigate the occurrence and foraging activity of harbour porpoises (Phocoena phocoena) around three artificial structures of different age and complexity. We deployed an array of echolocation click detectors (CPODs) in 2021, along a gradient of distances to these structures and assessed the extent to which porpoises were attracted to them. We also investigated the effect of these structures on the diel patterns of occurrence and foraging activity of porpoises. The probability of porpoise occurrence and foraging activity decreased with distance from offshore structures. A significant increase in porpoise occurrence and foraging was detected during night-time compared to daytime around all three offshore structures (< 200 m). Comparing pre- and post-installation porpoise detections, the daily patterns of occurrence and foraging activity shifted from a weak diel pattern before the structure was installed, to a strong nocturnal pattern when the structure was present. These findings provide evidence that marine mammals are attracted to man-made structures and that porpoises modify their diel patterns of occurrence and foraging activity around them. This research suggests that offshore structures play an important role as foraging areas for marine mammals and provides key information for the decommissioning process.,Echolocation detectors (CPODs; Chelonia Ltd) were deployed in August 2021 to study the occurrence and foraging activity of harbour porpoises around three redundant artificial structures within Scottish shelf waters: Jacky Wellhead O&G platform, Beatrice Bravo O&G platform, and Beatrice Demonstrator turbines (offshore renewable energy).,Data consist of 20 files and include the datasets and R code required to repeat all the analyses.

Technical method comparison of leaf area assessments from leaves scanned with a flatbed scanner.
Leaf scans were used for a technical comparison of different programs calculating leaf area. For this approach, a subset of leaf scans was compiled from trees in selectively logged forest at SAFE and in old-growth forest in Danum Valley and Maliau Basin, sampled during the BALI project traits campaign. Leaf area determination is compared for five different methods and twp groups of leaves: "easy" (mostly simple leaves and small to medium sized leaves that result in comparibly easy scans to analyse) and "tough" (usually big and compound leaves that lead to challenging scans with shadows). For the purpose of a methods comparison, leaf areas are not summed up per leaf or tree level but instead provided on the basis of each individual scan image.- DOI

Soil and litter chemistry, soil microbial communities and litter decomposition from tropical forest and oil palm
A study examining the interactions between soil chemistry, litter chemistry and soil microbial decomposers as controls on rates of litter decomposition across a tropical land use disturbance gradient. Co-located soil and litter samples were collected from old growth forest, moderately logged forest, heavily logged forest and oil palm plantations. Soil and litter were chemically characterised and soil bacterial and fungal community composition and abundance were measured. These were then combined in fully factorial ex-situ microcosms and measured litter decomposition rates at 3 time points during different stages of decomposition.- DOI
