Different habitat features can limit animal populations at different spatial scales. We examined habitat selection by Eurasian badger in a montado landscape in southern Portugal at four scales: core area (1 km2), home range (4 km2), social group territory (25 km2), and local population (100 km2). Our goals were to identify important habitats for conservation at each spatial scale (cell size) using candidate variables shown to be important by previous research. As expected, across all scales, badger occurrence was consistently and strongly correlated with dominance of cork oak and deciduous woodlands, and badgers seemed to avoid cultivated fields. Contrary to expectation, monocultures of conifers contributed positively to badger detection. The predictive ability of the models was poor at all scales, probably owing to our inability to include factors such as food, competitors, predators, undercover vegetation, and roads. Nonetheless, the models illustrate the importance to badgers of the montado, an ancient human-modified ecosystem that is threatened by current European Union agricultural conversion policies.

Oak trees are emblematic of California landscapes, they serve as keystone cultural and ecological species and as indicators of natural biological diversity. As historically undeveloped landscapes are increasingly converted to urban environments, endemic oak woodland extent is reduced, which underscores the importance of strategic placement and reintroduction of oaks and woodland landscape for the maintenance of biodiversity and reduction of habitat fragmentation. This paper investigated the effects of human urban development on oak species in California by first modeling historical patterns of richness for eight oak tree species using historical map and plot data from the California Vegetation Type Mapping (VTM) collection. We then examined spatial intersections between hot spots of historical oak richness and modern urban and conservation lands and found that impacts from development and conservation vary by both species and richness. Our findings suggest that the impact of urban development on oaks has been small within the areas of highest oak richness but that areas of highest oak richness are also poorly conserved. Third, we argue that current policy measures are inadequate to conserve oak woodlands and suggest regions to prioritize acquisition of conservation lands as well as examine urban regions where historic centers of oak richness were lost as potential frontiers for oak reintroduction. We argue that urban planning could benefit from the adoption of historical data and modern species distribution modelling techniques primarily used in natural resources and conservation fields to better locate hot spots of species richness, understand where habitats and species have been lost historically and use this evidence as incentive to recover what was lost and preserve what still exists. This adoption of historical data and modern techniques would then serve as a paradigm shift in the way Urban Planners recognize, quantify, and use landscape history in modern built environments.

Purpose
Despite increasing efforts to incorporate sustainability in curricula and practices of institutions of higher education, effective implementation remains challenging. The purpose of this study is to present an approach to incorporate sustainability into a practice-oriented research skills course, which was implemented at a small island state university in the Caribbean.


Design/methodology/approach
First-year university students followed a four-week course module, starting with the introduction of the sustainable development goals, and culminating in a symposium in which the students present the findings of their research projects to the campus community. Pre-course module and post-course module surveys measured the students' knowledge and perceptions regarding sustainability. These survey results were also compared with the result of a similar survey held for the university's employees.


Findings
The survey results suggested that following the course module increased students' knowledge about sustainable development, as well as their support for the university campus and its community putting more emphasis on teaching, practicing and encouraging sustainability. Interestingly, university employees scored significantly higher on the latter component than students, suggesting that in this case a lack of interest of the staff is not a barrier toward a sustainable campus.


Originality/value
The presented course module offers a novel and low-cost approach to introducing sustainability into a broad range of academic curricula, specifically tailored to the needs of institutes of higher education in small island states. The survey results suggest that this type of education may not only ensure reaching academic goals but also increase students' interest in sustainable development within their local environment.
