Table 3 Categories of exposure to code in the systematic map

From: What evidence exists on the possible effects of urban forms on terrestrial biodiversity in western cities? A systematic map protocol

Categories of exposure Description Example reference from test list or scoping exercise
Morphological characteristics Description of street widths and its spatial organization, building heights [32]
Connectivity Connectivity between urban items and vegetated areas (green spaces, urban gardens, remnants, etc.) [33]
Urban development scenarios Use of urban or ecological modelization [34]
Urban projects Comparing spaces before and after the construction of urban projects [35]
Urban density Study of sectors characterized by a variable density of housing, buildings and population [37]
Major types of urban areas Either large sectors such as "dense urban", "suburban", etc., in terms of degree of compactness or land-use patterns or description of the urban form through function (e.g. residential, business areas, industrial) [38]
Urbanization gradient Description of types of urban form even if the discriminating element is the percentage of urban land use by impervious surfaces [39]
