Predicting salmonid population ecology from individual fish responses to environmental changes: bridging behaviour, conservation and fisheries management.
… used in the management of the socio-economically and ecologically important chalk stream salmonid populations fail to incorporate fish behaviour and the interactions between fish with their environment and this limits their ability predicting management-relevant salmonid population responses to …

The Assessment of habitat condition and consevation status of lowland British woodlands using earth observation techniques.
… implementation of habitat preservation and management demands regular and spatially explicit monitoring of conservation status at a range of scales based on indicators. Woodland condition can be described in terms of compositional and structural attributes (e.g. overstorey, understorey, …

An Investigation of patterns of mammalian scavenging in relation to vertebrate skeletal remains in a Northwestern European context: forensic applications.
Mammalian scavenging, disarticulating, scattering and removal of human remains can alter and obscure both soft tissue and skeletal remains which are essential to making interpretations and identifications during forensic investigations. The effects of scavenging vary between regions, environments, …

Investigating the physical and ecological drivers of change in a coastal ecosystem: from individual to population scale impacts.
… of these changes are anthropogenically-driven and linked to long-term, climate-related phenomena. This thesis focusses on ecological change in soft sediment intertidal habitats. One of the largest harbours in Europe, Poole Harbour, is used as a case study. It contains a variety of important …

Functional analysis of secondary tropical dry forests in a region of the Colombia, Caribbean
… role conserving biodiversity in agricultural landscapes and this role is especially important for seasonally dry tropical forests (SDTF), one of the most threatened tropical forested ecosystems. The conservation value of secondary forest is increased by its capacity to maintain ecosystem …

Factors affecting the growth and recruitment of cyprinid populations of the River Wensum, Eastern England, with specific reference to roach Rutilus rutilus (L.).
… population of the River Wensum, Eastern England, has long been the topic of deliberation amongst the angling community due to a perceived decline in their catches since the 1970s. Analysis of fish population survey data collected by the Environment Agency and its predecessor organisations …

Habitat modelling and the ecology of the marsh tit (Poecile palustris).
Among British birds, a number of woodland specialists have undergone a serious population decline in recent decades, for reasons that are poorly understood. The Marsh Tit is one such species, experiencing a 71% decline in abundance between 1967 and 2009, and a 17% range contraction between 1968 and …

Impact of environmental change on ecological communities.
… impacts of environmental change on communities, and on individual species constrained by those communities, is seriously limited. However, as conservation efforts increasingly emphasise broad-scale approaches in terms of multi-species coverage and spatial scale, it is imperative that …

The foraging behaviour of granivorous birds: a mechanistic perspective.
… studied phenomenon for some groups of foragers and many mechanistic models of the functional response have been derived to account for variations in foraging behaviour. However, only a few functional response models have been applied to granivorous farmland birds and these models often have …

Analysis of the ecological principles underpinning forest landscape restoration: a case study of wood cricket (Nemobius sylvestris) on the Isle of Wight (UK).
Current woodland restoration programs are increasingly focussing on the creation of habitat networks in order to increase woodland cover and connectivity. However, the basic assumptions underpinning such strategies are largely untested for species associated with woodland habitat. For many woodland …

Evolution in the genus Arum: a comparative analysis of morpohological and genetic variation.
Testing the correlation of morphological and genetic marker variation enables the investigation of evolutionary processes. Knowledge of evolutionary processes can be used to identify those morphological characters that could be used to produce evolutionary meaningful taxonomies. This thesis aims to …

Integrating zooarchaeology into studies of Roman Britain and Medieval Russia.
This volume and supporting papers constitute the submission for an award of a PhD research degree by publication. Eleven works completed by the author within the last 15 years (eight published; three in press) have been submitted for consideration. All the papers are concerned with animal …

An Investigation of the key factors and processes that underlie the contemporary display of biological collections in British museums.
… prompted by the observed renaissance, explores and examines the factors and processes involved in the redevelopment of biological displays in British museums. Using a qualitative, grounded theory methodology and analytic process, the research focuses on three case study museums; Kelvingrove Art …

Livestock and landscape: exploring animal exploitation in later prehistory in the South West of Britain.
… generally only able to inform us about economy, and occasionally about symbolic behaviour. On the other hand, the use and division of landscape has been largely discussed in terms of social organisation. There has been a failure to appreciate that there is a reflexive relationship between …

Medical education, professional learning and action research in the health service: assessment, interventions and future models for General Practice vocational training of senior house officers.
… because of its large service commitment and poor educational structure, and this particularly applies to the hospital Senior House Officer (SHO) component of general practice vocational training. This study set out to assess the effect of local interventions to improve SHO education. This …

Sediment geochemistry - a case study approach.
… geochemistry of sediments is a very wide field and several important aspects must be taken into account, including, but not limited to, various methodological questions, the analysis of distribution patterns, determination of origins and the assessment of risks. Therefore, this research project …

Habitat suitablity modelling in the New Forest National Park.
… Forest National Park is a unique semi-natural landscape which contains many species and habitats which are rare and/or threatened. In order to effectively aid in the conservation of these species, particularly in the face of climate change, there is a requirement to know their habitat …

An Investigation into the successful establishment of a hay meadow community on clay capped landfill.
… species threatened by loss of existing natural and semi-natural habitats. Decommissioned landfill presents excellent opportunities for the creation of a number of habitat types. However, landfills are often sealed with a compacted clay cap which not only creates harsh growing conditions and poor …

The interaction of Sika deer (Cervus nippon Temminck 1838) with lowland heath mosaics.
… in many parts of the world. In the south of England large populations appear to be concentrated in landscapes comprising of mosaics of lowland heath, woodlands and grassland. Despite the association between the distribution of Sika deer and that of lowland heath, little is known regarding the …

An Evaluation of downland turf re-creation, using invertebrates as indicators.
… (SWD ESA) were used to evaluate re-created downland turf, a habitat created under one of the scheme management options. The novel habitat was compared to adjacent areas of established downland and to the edges of arable fields, by collecting vegetation data, and using invertebrates as indicators …
