© 2018 Elsevier Ltd The honeycomb worm Sabellaria alveolata is capable of building extensive bioconstructions, including what are currently considered Europe's largest biogenic reefs. The size and volume of these bioconstructions, however, vary greatly, such that not all habitats engineered by S. alveolata may be easily identified as reefs. Given that European environmental legislation protects marine habitats that are classified as “reefs” it is important to identity a clear set of definition criteria. Furthermore, quantifiable and unequivocal criteria are also needed to evaluate the ecological (health) state of these reefs, in order to best monitor and protect them. Here we …

Taxonomy, Biogeography And Ecology Of Andean Tardigrades At Different Spatial Scales, Balbina Ramsay
Taxonomy, Biogeography And Ecology Of Andean Tardigrades At Different Spatial Scales, Balbina Ramsay
School of Biological and Marine Sciences Theses
Micrometazoans are animals smaller than 2 mm. Their biogeography is poorly understood, and tardigrades provide a tractable phylum for exploring distribution patterns at a variety of scales. Polylepis forest habitat offers considerable advantages for making tardigrade comparisons across a wide range of scales in the Andes. This thesis aims to improve identifications of tardigrades with a character matrix approach, to assess the relative importance of habitat and bryophyte host on tardigrades, to describe the fine-scale spatial structure of tardigrade assemblages, and to estimate the sampling effort required for a reliable estimate of tardigrade diversity within Polylepis forest. Samples of bryophytes …

Economic Resilience In Great Britain: An Examination Of The Determinants Of The 2008 Crisis Impact On Gb's Local Authority Districts, Anastasios Kitsos
Other Faculty of Arts, Humanities and Business Theses
In 2008, a severe economic crisis hit economies around the world. Its effects included a significant loss of GDP and employment which led to several social ills associated with recessions. However, the crisis did not impact all places with the same severity. This thesis investigates the crisis impact across GB Local Authority Districts during 2008-2014 within a framework that utilises the concept of economic resilience. However, this concept does not have a universally accepted definition or methodology of investigation. Hence, the study adopts an operational definition, comparing the conditions in local labour markets before and after the start of the …

Pan-Mediterranean Holocene Vegetation And Land-Cover Dynamics From Synthesised Pollen Data, Jessie Woodbridge, Neil Roberts, Ralph Fyfe
More Faculty of Science and Engineering Research
AimThe Mediterranean is characterized by diverse and spatially heterogeneous mosaic landscapes. Within this study, a cluster analysis-based method is developed for the classification of Mediterranean vegetation types based on modern and fossil pollen datasets. The application of this approach to multiple pollen records spanning the Mediterranean region has allowed temporal variations in vegetation dynamics to be explored throughout the Holocene. We ask how far back stable baseline vegetation communities can be identified in the pollen record, and whether those types considered to be characteristic of the Mediterranean landscapes have been present in the past as well as at the present.LocationThe …

© 2017 International Association for Vegetation Science. Aims: To apply the Landscape Reconstruction Algorithm (LRA) to pollen count data from multiple sites to estimate local vegetation abundance and compare with charcoal-derived records of burning. Location: Exmoor, southwest England, UK. Methods: Pollen count data from 16 sites were transformed to estimates of distance-weighted vegetation abundance using the LRA (REVEALS and LOVE models), correcting for bias in pollen production and dispersal. Charcoal concentration data from six sites were normalized using Box-Cox transformation to produce z-scores. Moving-window correlation was undertaken to compare pollen percentage values for key taxa (Calluna, Poaceae) and localized burning. …

Eco-Efficiency Of High-Yielding Variety Rice Cultivation After Accounting For On-Farm Environmental Damage As An Undesirable Output: An Empirical Analysis From Bangladesh, N-E Sabiha, R Salim, S Rahman
School of Geography, Earth and Environmental Sciences
This study computes the eco-efficiency of high-yielding variety (HYV) rice production by including an on-farm environmental damage index (OFEDI) as an undesirable output using data envelopment analysis. It then identifies its determinants by applying an interval regression procedure on a sample of 317 farmers from north-western Bangladesh. Results reveal that the mean level of the OFEDI-adjusted production efficiency (i.e. eco-efficiency) is 89 per cent, whereas ignoring OFEDI adjustment (i.e. with OFEDI = 0) reduces the mean level of efficiency to 69 per cent, implying that the production of undesirable output or on-farm environmental damage induces an efficiency loss of 20 …

Background: Obesity and dental caries are two of the most common conditions affecting children and both have significant implications on children’s wellbeing and future health. Even though research into the relationship between the two conditions has been conducted for many years, results to date remain equivocal. Furthermore, the majority of the studies only examined individual-level determinants of the two conditions. Aim: The current work aimed to examine the nature, direction and effect size of the relationship between obesity and caries in children in Plymouth, United Kingdom. It also aimed to better understand the individual and the broader environmental determinants of …

Does Capture Method Or The Presence Of Aquatic Protected Areas Influence The Selective Harvest Of Behavioural Types In Largemouth Bass?, Ell Cooke, Alexander D.M. Wilson, Chris K. Elvidge, Sj Cooke
School of Biological and Marine Sciences
Selectively removing fish based on particular traits, such as body size, may shift trait abundance in the remaining population, resulting in a phenomenon called fisheries-induced evolution. Recently, there is growing interest in evaluating the effects of fisheries-induced evolution on fish behaviour. Aquatic protected areas (APAs) have been designated in some habitats in efforts to prohibit harvesting and maintain natural ranges of phenotypic variation for impacted species. Here, we attempted to test whether APAs that prohibit all forms of fishing have an evolutionary influence on adult largemouth bass (Micropterus salmoides) behaviour by investigating the relationship between capture method and behavioural type. …

Aggregations of living unattached corallines, previously often referred to as nodules, were given the name rhodoliths by Bosselini and Ginsburg ( 1971 ). Adey and MacIntyre ( 1973 ) provided an early discussion of their genesis and distribution. Such aggregations have long been known as maerl in the North East Atlantic, a Breton term for unattached thalli that lack a shell or pebble core (Irvine and Chamberlain 1994 ). Here, we provide an overview of rhodolith/maerl occurrence in the colder/temperate waters of the North Atlantic and summarize the distribution, species composition, biodiversity and ecological importance of these habitats.

Research Challenges And Conservation Implications For Urban Cat Management In New Zealand, Kh Kikillus, Gk Chambers, Mj Farnworth, Km Hare
School of Biological and Marine Sciences
Over the past 20 years, conservation efforts in New Zealand have moved from being concentrated in rural and isolated island locations, where exotic mammalian predators are often controlled, to begin to bring native fauna back to major cities. However, human–wildlife conflicts arise when conservation occurs in close proximity to cities. These are particularly intense when companion animals are involved either as potential predators or prey of high-value conservation animals. Within New Zealand, this conflict is particularly fraught around domestic cats (Felis catus) in the urban environment. Cats in New Zealand are recognised as major introduced predators of native fauna, but …

Eco-Engineered Rock Pools: A Concrete Solution To Biodiversity Loss And Urban Sprawl In The Marine Environment, Lb Firth, Ka Browne, Am Knights, Sj Hawkins, R Nash
School of Geography, Earth and Environmental Sciences
In coastal habitats artificial structures typically support lower biodiversity and can support greater numbers of non-native and opportunistic species than natural rocky reefs. Eco-engineering experiments are typically trialed to succeed; but arguably as much is learnt from failure than from success. Our goal was to trial a generic, cost effective, eco-engineering technique that could be incorporated into rock armouring anywhere in the world. Artificial rock pools were created from manipulated concrete between boulders on the exposed and sheltered sides of a causeway. Experimental treatments were installed in locations where they were expected to fail and compared to controls installed in …

Increasing The Depth Of Current Understanding: Sensitivity Testing Of Deep-Sea Larval Dispersal Models For Ecologists, Rebecca E. Ross, W. Alex M. Nimmo-Smith, Kerry L. Howell
School of Biological and Marine Sciences
Larval dispersal is an important ecological process of great interest to conservation and the establishment of marine protected areas. Increasing numbers of studies are turning to biophysical models to simulate dispersal patterns, including in the deep-sea, but for many ecologists unassisted by a physical oceanographer, a model can present as a black box. Sensitivity testing offers a means to test the models' abilities and limitations and is a starting point for all modelling efforts. The aim of this study is to illustrate a sensitivity testing process for the unassisted ecologist, through a deep-sea case study example, and demonstrate how sensitivity …
