Indeed, individuals of this species tend to aggregate under shelters maximizing their density when predation risks are high, and they select shelters that are scaled to their group size [29].
Generally, wolves minimised the risk of exposure at breeding sites by avoiding human-made structures, selecting shelter from vegetation and avoiding agricultural lands.
Selecting shelter sites and evaluating the spatial distribution of urban shelters in Jing'an District are essential preconstruction steps.
The selected shelter models are all published by the International Federation of Red Cross and Red Crescent Societies (IFRC) in Transitional Shelters 8 Designs (IFRC 2011).
Equation 3 formulates the capacity constraint, which ensures that the capacity of a selected shelter can meet the demands of residents, while Eq. 4 expresses the distance constraint, affirming that the distance between communities to a selected shelter is less than the maximum evacuation distance.
In this study, it is assumed that all residents in a community will be allocated to the same shelter using the shortest evacuation route from the community to the selected shelter.
When two or more eligible women were identified in a selected shelter, the youngest woman was enrolled.
Potential study participants are randomly selected from an anonymous list of all employees with ID working in each randomly selected sheltered workshop and then contacted by the staff of the sheltered workshops, informed about the study and asked whether research staff may contact them.
It was decided for economic reasons that a maximum of 15% of all employees of each randomly selected sheltered workshop will be assessed, so that the number of sheltered workshops to be randomly selected from each specific stratum resulted directly from the randomisation process.
