Connecting The Dots - Recognition Of Artificial And Natural Shapes Relies On Representing Points Of High Information, Gunnar Schmidtmann, Nicholas Baker, Kevin J. Lande, Filipp Schmidt

School of Health Professions

Physiological and psychophysical evidence suggests that the visual system represents object outlines using prominent curvature features, particularly regions of extreme curvature (convex maxima and concave minima). These curvature extrema often coincide with points of high informational content (“surprisal”), but this relationship is only correlational. It remains unclear whether the visual system explicitly encodes curvature extrema or instead prioritizes the most informative contour locations. To address this, we conducted two shape-matching experiments comparing the roles of curvature extrema and surprisal in shape representation. Observers performed match-to-sample tasks in which smooth reference shapes were matched to simplified polygonal versions created by connecting …

Shelled Shut-Ins: A Conditional Escape Task Showing Perceptual Awareness In Hermit Crabs, Ari Drummond, John Spicer, Mark Briffa

School of Biological and Marine Sciences

Sentience is an increasingly popular topic in animal welfare and behavioural research. However, studying sentience can be difficult and contentious. Sentience has frequently been associated with ‘feelings’ and ‘subjective states’ not directly accessible to human observers; thus, investigating awareness in animals could be an alternative approach. Frameworks of awareness have been developed for the experimental examination of cognitive capacities that might underpin ‘feelings’ as affective states and subjective experiences. Using a framework of four hierarchically arranged levels of awareness (that is, perceptual, cognitive, assessment and executive), the awareness of an intertidal crustacean, the common hermit crab, Pagurus bernhardus , was …

Groundwater Spatial Variability Within An Atoll Island: Assessing Shallow Aquifer Heterogeneity With Geophysical And Physicochemical Measurements, N. I. Tobon-Velazquez, G. Masselink, T. J. O’Hare, R. Bates, F. K.J. Oberle, C. D. Storlazzi, D. C. Conley

School of Biological and Marine Sciences

This study examines the spatial variability of shallow groundwater on Dhigelaabadhoo Island using electromagnetic induction surveys, groundwater monitoring, and sediment analyses. The research reveals how variations in island morphology—such as differences in elevation, reef flat width, and sediment composition—affect the spatial distribution of groundwater lenses and the overall aquifer dynamics. Saltwater intrusion is especially pronounced in low elevated areas, with narrow reef flat plate and areas where higher hydraulic conductivity—driven by the presence of coarser sediments—is observed, whereas regions characterized by finer sediments, higher elevation, and wider reef flat plates tend to support more symmetric and less saline groundwater lenses. …

Testing The Transferability Of Ai Models For Cold-Water Coral Detection And Classification, Kyran P. Graves, Louise Allcock, David K.A. Barnes, Amelia E.H. Bridges, Kerry L. Howell

School of Biological and Marine Sciences

The proliferation of accessible deep-water imaging platforms has resulted in the acquisition of vast amounts of image data, resulting in an analysis bottleneck. Object detection is now being applied to assist the image annotation process, with the potential to reduce analysis time. However, for object detectors to effectively tackle the scale of the challenge, models need to be generalisable to allow the transfer between imaging platforms and in space. This study trains YOLOv5 object detection models to identify six coral morphology groups using annotated imagery collected by ROV ISIS in the UK (JC136). Model performance was tested with independent datasets …

Post-Release Mortality Of European Bass (Dicentrarchus Labrax) Discarded From Small-Scale Estuarine Fishing, J. E. Stewart, T. Stamp, P. Davies, A. Hall, T. Robbins, L. Stewart, E. V. Sheehan

School of Biological and Marine Sciences

Estuaries provide essential habitats for many fish species, but their confined and accessible nature may increase fish vulnerability to capture, and few empirical studies have quantified the value of restricting net fisheries in such areas. Furthermore, management measures for some fisheries promote discarding (e.g., of European sea bass; Dicentrarchus labrax), yet the mortality of fish discarded from small-scale inshore fisheries is poorly understood. We used condition assessments, Reflex Action Mortality Predictor scores and acoustic tracking to evaluate post-release mortality of bass captured in small-scale estuarine netting and angling. Gillnet-caught bass exhibited a range of stress responses and 20%–24% mortality shortly …

Investigating Spatial And Seasonal Differences In Microgastropod Assemblages Within The Little-Studied Camamu Bay, Brazil: A Potential Bioindicator For Remote Tropical Areas?, Francisco Kelmo, Sol De Maria Cesar Ferreira, Eduardo Henrique Galvão, Martin J. Attrill

School of Biological and Marine Sciences

This study investigates spatial and seasonal variation in the assemblages of benthic microgastropods (snails < 5–10 mm in length) within a poorly studied tropical bay. As these organisms are abundant, diverse and relatively easy to sample, with well-established taxonomy, they may prove a highly suitable group for ecological studies in such areas. Sediment samples were collected from three river basins in Camamu Bay, Brazil, during the wet and dry seasons. A total of 132 microgastropod species was recorded, demonstrating high diversity. The most abundant species were Eulithidium affine, Bittiolum varium, Cerithium atratum, Vitta virginea and Schwartziella bryerea. The least abundant species were Tenaturris gemma, Turbinella laevigata, Petaloconchus erectus, Parviturboides interruptus and Vitrinella cupidinensis. Statistical analysis revealed significant seasonal and spatial differences in diversity and assemblage composition, which correlated with environmental gradients. The results suggest that microgastropods are a suitable component of the biota for ecological and applied studies in marine sediments, particularly in remote tropical locations where full macrofaunal analysis may be challenging. Whilst further testing across impact gradients is needed, this approach offers a practical solution for ecological investigations in remote regions with limited taxonomic expertise and highlights microgastropods as a useful indicator taxon for impact biomonitoring in tropical marine sediments.

Mitochondrial Dysfunction In Alzheimer’S Disease And Related Sex Differences, Afzal Misrani, Conelius Ngwa, Fudong Liu

Faculty, Staff and Student Publications

Alzheimer's disease (AD), the most common form of dementia, accounts for 70% of cases and remains a major healthcare challenge due to its rising prevalence and lack of disease-modifying treatments. Clinically, AD is a sexually dimorphic disease. Women exhibit more rapid cognitive decline and accelerated brain atrophy during mild cognitive impairment and early dementia, whereas men more frequently present cardiovascular comorbidities, earlier mitochondrial dysfunction, and greater neuropsychiatric symptoms. AD is marked by amyloid-β (Aβ) plaques, neurofibrillary tangles, neuroinflammation, and neuronal loss, with mitochondrial dysfunction emerging as a key early contributor that exhibits sex specific phenotypes. Mitochondria are vital for neuronal …

Faculty, Staff and Student Publications

Background and purpose: We evaluated agreement and performance of non-contrast head-computerized tomography (NCHCT) and CT-perfusion (CTP) in identifying large core infarct in acute ischemic stroke (AIS) due to large vessel occlusion (LVO) undergoing endovascular therapy (EVT), using MRI as reference.

Methods: From our prospective multicenter registry, we identified patients with LVO-AIS due to internal carotid artery or middle cerebral artery M1occlusions who underwent EVT between 2017 and 2024. Final infarct volume (FIV) was defined using 24-48 h post-EVT diffusion-weighted imaging magnetic resonance imaging (MRI-FIV). To limit infarct growth bias, only patients with CTP-to-EVT start time < 3 h were included. Large core infarct was defined at FIV thresholds: 50, 70, and 100 mL. The primary outcome was agreement between NCHCT and CTP in identifying large core infarct using kappa-statistics. Large core was considered if NCHCT-ASPECTS< 6 or rCBF< 30% volume>70 mL on CTP (RAPID/Viz.AI). …
