Dispersal_Data sheet1
Nb: row number
Study_id: one id per study per study species (same as List_studies sheet)
Type_dispersal: Natal dispersal / Breeding dispersal / Both types
Age_class: Juvenile (meaning juvenile and subadult) / Adult / All
Sex_class: Male / Female / All
Other_class: can be a treatment class / population / year etc = give details when
appropriate for multiple estimates per age and sex class per study
Dispersal_metric (all metric are reported in %, meters and day units)
1. Age at dispersal: age at which individuals dispersed (when available, has not been
systematically searched for at the beginning of the literature survey)
2. Daily movement capacity = total movement distance traveled (m per day) during
dispersal movements (sometimes difficult to distinguish from standard
movements)
3. Dispersal distance = distance traveled during dispersal (in m)
4. Dispersal fraction: % of individuals moving from one patch to another (the others
are residents)
5. Dispersal kernel: some aspects of the dispersal kernel (in meters)
6. Genetic dissimilarity : Fixation index Fst value at a given spatial scale of enquiry
or an estimate of Fst
1
Qualitative patterns (age / sex / scale of dispersal)
7. Genetic dissimilarity slope and intercept: estimates of the components of the
isolation-by-distance model of Rousset (1997) when available (unfortunately not
all studies have done this in a standardized manner)
8. Immigration fraction: % of individuals recruited in the population from another
population (the others are residents)
9. Incidence function: exponential parameter of the classical Hanski definition of the
incidence function, describing potential decrease of dispersal with distance
10. Range expansion: contemporary estimate of range expansion (m/year)
Genetic_marker: type of genetic marker used for genetic estimates
Shape: shape of the dispersal kernel or movement kernel (see terminology in the sheet)
Metric_mean: mean of the estimate
Metric_SE: standard error of the estimate when available
Metric_scale: spatial scale (meters) at which the estimate was obtained
Metric_timing: time duration during which the estimate was obtained
Number_individuals: sample size for the estimate
Number_demes: number of study populations
He: expected heterozygosity
Ho: observed heterozygosity
Comment: usually some free comment on how data were extracted from the reference
