Either spring breeding or autumn breeding. Taken
from Desender et al. (2010) and Ribera et al. (2001)
1=carnivore (Harvey et al. 2008; Ribera et al. 2001)
1=herbivore (Harvey et al. 2008; Ribera et al. 2001)
1=omnivore (Harvey et al. 2008; Ribera et al. 2001)
1=brachypterous species (Luff 2007, Lin et al. 2007)
1=wing dimorphic speices (Luff 2007, Lin et al.
2007)
1=macropterous species (Luff 2007, Lin et al. 2007)
Attribute
Female body size in mm (Roberts 1996)
Number of months adult females active 1=short (35 months); 2=medium (6-7 months); 3=long (>7
months). Taken from Harvey et al. (2002)
Standardised niche parameters between 0 and 1.
Niche position is 0 for the species which prefer the
moistest habitats and 1 for the species which
prefer the driest habitats (Entling et al. 2007)
Standardised niche parameters between 0 and 1.
Niche position is 0 for the species which prefer the
most open habitats and 1 for the species which
prefer the most shaded habitats (Entling et al.
2007)
1=exact species is listed as ballooning in Bell et al.
(2005)
1=active hunting strategy (Uetz et al. 1999)
1=running hunters (Uetz et al. 1999)
1=ambush hunters (Uetz et al. 1999)
1=stalking hunters (Uetz et al. 1999)

1=Mega/meso/microphanerophyte;
2=Chamaephyte; 3=Hemicryptophyte; 4=Nonbulbous geophyte; 5=Therophyte. (Hill et al. 2004)
1=perennial; 2=biennial; 3=annual (Hill et al. 2004)
1=woody species (Hill et al. 2004)

1=seeds dispersed by wind (Grime et al. 2007)
1=too small to be measured easily; 2=≤ 0.20 mg;
3=0.21-0.50 mg; 4=0.51-1.00 mg; 5=1.01-2.00 mg;
6=2.01-10.00 mg; 7=≥ 10 mg. (Grime et al. 2007)
1=little or no vegetative spread; 2=Tussock-forming
graminoid, may slowly spread; 3=Rhizome shortly
creeping; 4=Rhizome far-creeping. (Hill et al. 2004)
1=transient seed banks present during the summer
and germinated synchronously in autumn;
2=transient seed banks present during winter and
germinated synchronously in late winter or spring;
3=a small amount of seed persists in the soil, often
for >5 years but concentrations of seed in the soil
are only high after seed has just been shed;
4=there is a large bank of long persistent seeds in
the soil throughout the year. (Grime et al. 2007)
