ABSTRACT The effective population size ( N e ) is a key parameter in conservation and evolutionary biology, reflecting the strength of genetic drift inbreeding. Although demographic estimations are logistically time‐consuming, methods have become more widely used due to increasing data availability. Nonetheless, accurately estimating remains challenging, with few studies comparing estimates across molecular markers types estimators such as single‐sample based on linkage disequilibrium or sibship analyses versus temporal variance allele frequencies. This study aims at bridging this gap by analysing temporally spaced populations southern damselfly Coenagrion mercuriale ), bioindicator Odonata species concern found southwestern Europe's freshwater stream networks. A total 77 local were sampled from semi‐urbanised area located eastern France near Strasbourg city, yielding 2842 individuals that genotyped microsatellites 958 which also for 2092 SNPs. Spatial structure was stable over time, suggesting porosity between alternate‐year cohorts. When accounting spatial structure, consistent each set markers. Biologically meaningful results obtained when effect migration minimising considering metapopulation level differentiation boundaries. In terms applied management, most depicted metapopulations displayed large , indicating no immediate need measures mitigate anthropogenic pressures, provided continuous suitable network maintained. However, urbanisation negatively impacted levels close city. Because inform decisions, caution crucial interpreting estimates, especially continuously distributed undergoing migration. Altogether, our highlights challenge obtaining robust necessity careful interpretation relevant guidelines.
