From: Narrow environmental niches predict land-use responses and vulnerability of land snail assemblages

Light preference | Degree to which species occur in direct sunlight or shaded conditions | Deep shade, light shade, no shade, indifferent |
Humidity preference | Degree to which species occur at wet or dry conditions | Wet, moist and dry |
Drought resistance | Degree to which species can survive dry periods | Hours, days, weeks, months |
