Abstract:
Habitat and dietary preferences and ranging behaviour were assessed from January 1989 to May 1991 in the nearly treeless Pennine uplands at Allenheads, using radio-telemetry, transect walks and faecal analysis. Male home range size was smaller than female (maximum 455 hectares). The population density of 0.07 birds/hectare was average for Black Grouse. Mortality was mainly due to predation. On four occasions (N=15) radio-tagged hens did not breed. Chicks fed predominantly on invertebrates in their first two weeks of life, with vegetation predominant thereafter.

Abstract:
Aspects of the ecology of black grouse (Tetrao Tetrix), a species of international conservation concern, in commercial plantation forests were investigated between 1996 - 1998 at three study areas in Scotland. The aim was to identify the species' habitat and area requirements in first and second rotation forestry. The distribution of males was assessed using lek surveys and studied at two spatial scales in the mixed rotation forest landscape of Cowal, Argyll and at two spatial and temporal scales in highland Perthshire - a less afforested region. In addition, a radio-tracking study was underta

Abstract:
Ecological modelling is of great benefit to conservation research by allowing ecologists to investigate natural systems and make predictions about future conditions; applications of ecological modelling have been greatly improved in recent decades by methodological and technological advances. One research area where ecological modelling can contribute greatly is research into the impact of environmental changes on plant and animal populations (McRae et al. 2008). Land use changes have the potential to impact species of conservation concern through habitat loss and fragmentation, an effect that

As planted forests mature and are clearfelled in patches, second rotation tree crops (restocks) become available to black grouse, a species of conservation concern in the UK.

The aims of this study therefore, were to investigate the recovery of field-layer vegetation and the invertebrate population from restock through to canopy closure of planted trees, assess the duration of habitat availability and food resources to black grouse, and understand how forest management could

A previous study with a group of adolescents, made up of 40 boys and 26 girls from 6th. to 8th. grades, showed personalized preferences, without a group tendency and linked to complex games.

Doutoramento em Engenharia Florestal e dos Recursos Naturais - Instituto Superior de Agronomia<br>This study evaluates the agricultural intensification effects on steppe bird populations of cereal fields and fallows. Through the analysis of landscape dynamics between 2002–2011, a gradient of agricultural intensification was identified in selected areas of Baixo Alentejo. In cereal fields, total bird abundance of steppe and resident birds decreased along the intensification gradient. During the breeding season, this trend should be related to an increase in height and density of vegetation

(+)-(2R,3R)-1,1,4,4-Tetraphenylbutane-1,2,3,4-tetraol (TETROL) and its derivatives were reacted with varying molar ratios of titanium isopropoxide (2:1, 1:1 and 1:2 tetraol:titanium isopropoxide) in an attempt to prepare potential titanium-based tetraol catalysts for enantioselective transformations. In each case, infrared and HNMR spectra suggested that the product was formed. We tentatively proposed that the structure of the catalyst was a spiro-type, but we could not determine conclusively what its exact structure was, despite using numerous techniques at our disposal (molecular modelling c

Abstract:
Re-experiencing trauma in the form of intrusive, image-based memories (here referred to as flashbacks) is a hallmark symptom of Post-Traumatic Stress Disorder (PTSD). There are successful treatments available for full-blown PTSD; however, these can only be administered one month post trauma. There are limited interventions that can be administered to reduce flashbacks in the early aftermath of trauma. The overarching aim of this thesis was to use an experimental psychopathology approach, the trauma film paradigm, to investigate the reduction of flashbacks post-trauma using the cognitive task,
