Table 1. Study design and species trait moderator variables used in the meta-analysis.

Moderator Type	ModeratorVariable	Categoryor Range	Description
StudyDesign	Study Type	Amount-based	Wetland amount was measured as the percent wetland area in a landscape orbuffer (area-based buffers)
		Configuration-based	Wetland amount was measured as the number of wetland patches in a landscape,or using wetland isolation (nearest-neighbour distances) or connectivity(incidence function model) metrics
	Sampling Effort	Area-dependent	Sampling effort increased in proportion to the sampled wetland area
		Area-independent	Sampling effort was consistent across sampled wetlands
		Unknown	Sampling effort was unknown
	Patch Area	Included	Sampled wetland area was included in the calculation of wetlandamount in the landscape
		Not included	Sampled wetland area was not included in the calculation of wetlandamount in the landscape
SpeciesTrait	Home RangeSize	0.001–35600	Mean annual home range or territory size (ha)
	Body Length	2.5–1200	Mean body length across both sexes (cm)
	Reproductive rate	2–16000	Mean litter or clutch size multiplied by the mean number of litters orclutches per year
