The sand lizard in Britain is well on the way to extinction, thanks to the destruction of its favoured habitats – sand dunes and dry heath. The author, who has been engaged in full-time research on the surviving populations, has started breeding sand lizards in captivity, using animals taken from sites that are being destroyed, and hopes to reintroduce them in protected areas.

The Impact

Purpose The purpose of this study is to assess the role of animals in creating a satisfactory experience at a natural park by investigating the impact on visitors of the exposure to, or absence of, fauna, towards the visitors’ overall experience. Design/methodology/approach The work is based on a quantitative data collection of tourists visiting a nature park. Altogether, 532 valid questionnaires were collected and used for the analysis. A series of factor analyses was conducted on pull and push factors for animal encounters. The resulting factor domains (FDs) were used as independent variables in ordinal logistic regression models to describe customer satisfaction. Findings The results of this study show that important FDs characterize the main visitor characteristics. Although human–animal encounters are an important factor for some visitors, the encounters should be encouraged in the most natural manner possible and not in captivity. This brings us to the concept of “Interpretation”, where guides and guided tours can help with the encounters. Information given prior to and during the visit can ensure visitors are aware that animal encounters are subject to nature and cannot be guaranteed. Originality/value The presence of areas where a number of animals are in captivity and can be viewed by visitors is an important decision for national parks and protected areas, as animals represent a potential attraction for visitors. Nevertheless, this decision creates an ethical dilemma in relation to the exploitation of animals, exacerbated by recent and increasing pressure on sustainable management. This study provides valuable results for guiding park managers in making reasoned decisions.

Microhabitat separation and diel activity patterns of Planigale gilesi and P. tenuirostris (Marsupialia: Dasyuridae).

Diel activity patterns and microhabitat use by the partially subterranean dasyurid marsupials Planigale gilesi and P. tenuirostris were studied in captivity. In the laboratory, a chamber was constructed that had a surface area and 'underground' cracks and cavities typical of the species' natural microhabitat. Infra-red light beams monitored the daily activity of individuals over 3 consecutive days under simulated photoperiods and temperatures typical of summer and winter. The larger species, P. gilesi, is more active than P. tenuirostris and, under summer conditions, is nocturnal; in winter it becomes more diurnal. Planigale tenuirostris is primarily nocturnal under summer and winter conditions. Both P. gilesi and P. tenuirostris exhibited short-term activity cycles that respectively, were: in summer 1 h 40 min and 1 h 25 min, and in winter 3 h 21 min and 2 h 56 min. Frequencies of activity bouts showed diel variations in P. gilesi but were constant in P. tenuirostris. Frequencies of rests showed diel variations in both species. Changes in total activity and in the proportion of surface-related activity are closely interrelated between P. gilesi and P. tenuirostris and may operate to reduce possible competitive interactions.

The London School of Economics was founded in 1895 to teach vocational and commercial subjects to part-time students. By 1920 the majority of students were full-time, studying the London BSc (Econ.) degree that was, however, a general social sciences degree for which very few students pursued the economics major option. The appointment of Lionel Robbins as Professor of Economics in 1929 opened the way for undergraduate teaching at the LSE to be moved towards economics, with staff appointments being made that would further this end. The bulk of the student body, however, continued to pursue a broad social sciences pathway, and it was only by shutting down the BCom degree in the later 1940s that Robbins was eventually able to bring about the shift from a broadly vocational school to one in which ‘modern’ social sciences dominated.

Visibility measurement is the most human-oriented measurement discussed because the objective of such measurement is to determine the distance at which humans (pilots, seamen, etc.) can see objects. Thus we are concerned with light that can be seen by humans (0.4 to 0.7μm), the way human eyes perceive such light, and then with the transparency of the atmosphere. Throughout this chapter, in the discussion of atmospheric transparency or absorption, the range of wavelengths from 0.4 (violet) to 0.7μm (red light) will be assumed. Cloud height is a remote sensing measurement but is included here because airport meteorological systems usually include a cloud height sensor. According to the WMO, meteorological visibility by day is defined as the greatest distance that a black object of suitable dimensions, situated near the ground, can be seen and recognized when observed against a background of fog, sky, etc. Visibility at night is defined as the greatest distance at which lights of moderate intensity can be seen and identified.

The Way

SUMMARYIn this paper, we puzzle the way that sovereignty has been a sketchily present dynamic in conservation discourses. In the case of the world's many island communities whose colonial histories extend into the present in virtually every domain, silences around sovereignty in conservation contexts are particularly notable for the way they suggest the enduring domination of local communities by distant metropoles. Here, we provide a review of several critical issues in Pacific Islands contexts – biosecurity, food security, intellectual and material property rights and protected areas – that highlight the importance of conceptualizing sovereignty beyond the state to better enhance conservation outcomes. The novel approach we take in regard to these problems is to encourage conservation practitioners to more deeply engage with the ‘ecological futures’ that indigenous and local island communities are weaving in a period of active (re)articulations of sovereignty in conception, legal constitution and everyday engagements with island environments.

Britain has a mainly temperate climate, but there are some hot habitats, such as sand dunes, heathlands and shallow-water areas, which may be vital to the survival of certain species – Dartford warbler, sand lizard, natterjack toad are examples. The author suggests it is therefore vital to conserve extensive examples of these habitats to preserve the wildlife that depends on them. Unfortunately they are habitats that have suffered considerable destruction.
