“…However, these rare events can be ecologically relevant and could also contribute significantly to gene flow. Landscape genetics seems a more sensible way forward to assess dispersal ability (Cox et al ., 2020), taking advantage of recent development of microsatellites (McKeown et al ., 2018). CMR and telemetry should not be abandoned, only repurposed (see below for CMR and “Habitat” for telemetry).…”

“…Total abundance differs between years (Supporting Information Table S4), probably related to winter rainfall (Méndez et al, 2017). Four‐year cycles in abundance related to a fixed 4‐year development time (Drake, 1994) can be rejected (Cox et al ., 2020).…”

“…Local studies in Ukraine also found high genetic diversity (Snegin, 2011(Snegin, , 2014 but showed indication of lower genetic diversity in an anthropogenically influenced population (Snegin et al, 2017). A population genetic study near Brussels indicates a loss of the metapopulation structure in the last decades (Cox et al, 2020).…”

Reliable information for the conservation of many insects is lacking due to a poor knowledge of their ecology. Here, we review the biological knowledge about the European stag beetle (Lucanus cervus), in which recent advances are improving the basis for successful conservation. A review of the biological and ecological literature about this species identified an exponential increase in both total and peer‐reviewed articles after Natura 2000 regulations. Recent progress in the last two decades has been made in solving taxonomic problems, as well as in habitat description through radiotelemetry and habitat models. Dependence on large old‐growth forest has given place to a more complex picture of habitat use along the distribution range of this species. Monitoring protocols have been developed that will allow to assess conservation status and actual decline. Stag beetle conservation would benefit from a better understanding of larval demography, quantification of microhabitat requirements, landscape genetics and quantification of historical and current threats. Lessons learned include the need to solve taxonomic problems and to target methodological bottlenecks. The stag beetle is one of the few European saproxylic organisms that can engage the broad public through outreach activities and therefore its role as an umbrella species should be promoted.

“…These, coupled with the vulnerable characteristics inherent to these habitat specialists-such as limited and sex-biased dispersal, a small effective population size and a naturally scattered distribution (Harvey et al, 2011;Rink & Sinsch, 2007)collectively impact their population abundance, long-term sustainability and genetic composition (Frankham et al, 2002;Krauss et al, 2003;Miklín & Čížek, 2014). However, saproxylic beetles in general have received limited genetic study before their decline, and only a few investigations have delved into the effects of patchy habitat distribution on gene flow, genetic diversity and population structure (Cox et al, 2020;Melosik et al, 2020;Oleksa, 2009;Oleksa et al, 2013Oleksa et al, , 2015Schauer et al, 2018).…”

“…Due to its rarity, charismatic appearance and various intriguing aspects of its life, numerous ecological data are available on this beetle (Bardiani et al, 2017;Chiari et al, 2014;Mader, 2010;Rink & Sinsch, 2007;Tini et al, 2017). Genetic investigations conducted by Solano et al (2016), McKeown et al (2018 and Chen et al (2019) have also contributed to our understanding, although there is a noticeable scarcity of studies focusing on population genetics (Chen et al, 2019;Cox et al, 2019Cox et al, , 2020McKeown et al, 2018;Popa et al, 2023;Snegin, 2011Snegin, , 2014Solano et al, 2016). The genetic information is crucial for guiding conservation efforts and supporting sustainable habitat use.…”

Despite the significance of saproxylic beetle species for ecosystems, the investigation of fine‐scale population genetics within the stag beetle, Lucanus cervus, remains notably limited. Because of their limited dispersal distances and habitat fragmentation, high genetic structure and low genetic diversity are expected in its populations. To evaluate the impact of habitat fragmentation on genetic diversity and structure, we examined 150 specimens of L. cervus from three sites in western Poland: two forest stands and one stand located in an Oak avenue. We utilised 19 microsatellite DNA loci for this examination. Results of neighbour‐joining analysis and principal coordinates analysis, values of differentiation indexes (G'ST, D(Jost) and FST) and rare/private allele frequencies indicated weak genetic differentiation among individuals collected from the tree sites. A spatial component to the genetic structure was identified through STRUCTURE (LOCPRIOR), isolation by distance tests and spatial autocorrelation analysis. The genetic diversity remained relatively high (HE: 0.49–0.51), with no inbreeding observed and no significant differences in mean relatedness among individuals from sampling sites. Limited genetic differentiation between the individuals of L. cervus from the investigated sites may result from a lag time since fragment isolation, unrestricted gene flow and marker/sample size limitations. Though weak, the significant differentiation between two of the sites may be linked to environmental differences and distance. Genetic data support treating individuals from forests as a single management unit. Non‐invasive sampling suffices for genetic studies, but achieving balanced sampling is crucial for precise historical demography estimates of endangered species.
