Leaf litter species preference in the pill bug ( Armadillidium sp. ) Emily Byrne Kevin Isherwood Greg McGuire Jonathan O’Keefe
The pill bug, Armadillidium sp. Widespread terrestrial crustacean Susceptible to desiccation Physiological adaptations Behavioural adaptations Respiratory mechanisms
Habitat preference Flexible diet comprised primarily of decaying matter Moist, dark environments Decaying > fresh leaf litter
Species- specific leaf litter High quality litter> low quality litter Panlasiui (2011) Oak, Quercus agrifolia, > Blue Gum, Eucalyptus globulus Tuck & Hassall (2003) Dicotyledon litter > grass litter Morisawa et al. (2002) Japanese Cedar, Cryptomeria japonica – natural repellant
Current study Investigate if the pill bug, A rmadillidium sp. has a preference for local leaf litter species Hypothesis: individuals will prefer broad-leaf species
Experiment 1: Leaf litter species preference 3 trials Wet leaves Dark environment Picea rubensQuercus rubens Thuja occidentalis Acer saccharum
Experiment 2: Effects of moisture and humidity Spruce dried in oven Maple dunked in well water
Discussion Hypothesis: preference for broad leaf species Drying of leaves potentially a major contributor
Discussion Cloudsley-Thompson & Constantinou 1987 Presence of a thigmokinetic response Takeda 1980 Possible aggregation pheromones
Aims of the session: Take measurements of leaves + see if xerophytes have a different pattern of mass loss Learn about the adaptations xerophytes have.
