“…Moreover, the mixed model offered the opportunity to study specific effects of landscape through random effect analysis. However, this opportunity to study the whole data set of replicated landscapes with a mixed model seems to be rarely used (Castillo et al., ; Short Bull et al., ; Villemey et al., ; but see Jaffé et al., , who did not replicate landscapes but species).…”

“…Replication offers the opportunity to extract general landscape effects across all replicates but also to focus on the specific contribution of each landscape. The few studies using replicated landscapes show that generalization was not straightforward and that extrapolating from one landscape to another could be misleading (Castillo et al., ; Hand et al., ; Richardson et al., ; Villemey et al., ). For example, by comparing twelve landscapes, Short Bull et al.…”

Functional connectivity in replicated urban landscapes in the land snail (Cornu aspersum)

et al. 2018

Urban areas are highly fragmented and thereby exert strong constraints on individual dispersal. Despite this, some species manage to persist in urban areas, such as the garden snail, Cornu aspersum, which is common in cityscapes despite its low mobility. Using landscape genetic approaches, we combined study area replication and multiscale analysis to determine how landscape composition, configuration and connectivity influence snail dispersal across urban areas. At the overall landscape scale, areas with a high percentage of roads decreased genetic differentiation between populations. At the population scale, genetic differentiation was positively linked with building surface, the proportion of borders where wooded patches and roads appeared side by side and the proportion of borders combining wooded patches and other impervious areas. Analyses based on pairwise genetic distances validated the isolation-by-distance and isolation-by-resistance models for this land snail, with an equal fit to least-cost paths and circuit-theory-based models. Each of the 12 landscapes analysed separately yielded specific relations to environmental features, whereas analyses integrating all replicates highlighted general common effects. Our results suggest that urban transport infrastructures facilitate passive snail dispersal. At a local scale, corresponding to active dispersal, unfavourable habitats (wooded and impervious areas) isolate populations. This work upholds the use of replicated landscapes to increase the generalizability of landscape genetics results and shows how multiscale analyses provide insight into scale-dependent processes.

“…Even heterogeneous arable land has been shown to provide habitats for many butterfly species, highlighting the importance of conserving mosaic landscapes (Loos et al, 2014). Furthermore, landscape structure affects butterfly dispersal between habitat fragments: some landscape features can enhance dispersal whereas others act as barriers (Ricketts, 2001;Klaus et al, 2015;Villemey et al, 2016).…”

High cover of forest in the landscape matrix has been shown to weaken the negative effects of habitat fragmentation on grassland butterflies. No studies have however focused on examining species‐specific responses of grassland butterflies to forest. The data from 3 years of butterfly monitoring in Southern Finland were used to test whether the amount of forest cover in the surrounding landscape affected the abundance of grassland butterfly species in semi‐natural grasslands, field margins, and forest edges. More than half of the studied species benefitted from high cover of forest. Species with the strongest preference for forested landscapes were Lycaena virgaureae, Argynnis adippe, Argynnis aglaja, and Boloria selene, which probably find suitable resources in herbaceous habitats at forest edges and clearings. Several small‐sized species were positively affected by surrounding forest cover in field margins but not in the other habitat types. Although field margins are suboptimal habitats for grassland butterflies, they provide important corridors for dispersal. High cover of forest in the landscape matrix may enhance butterfly dispersal along field margins by reducing windiness, which is likely to be most important for small‐sized species with poor dispersal capacity. The most abundant grassland species showed little or no preference for forested landscapes. Our results suggest that high cover of forest enhances the persistence of most grassland butterflies, including declining species, in boreal agricultural landscapes. The responses to forest are however strongly dependent on species‐specific properties and habitat types.

“…It shows medium dispersal capacity with mean dispersal distances ranging from about 50 to 300 m (Schneider et al, 2003; Ouin et al, 2008; Stevens et al, 2013). Previous studies revealed that both land cover (arable lands and forests) and LTIs (motorway and railway) could affect its dispersal (Villemey et al, 2016; Remon et al, 2018). Finally, Abax parallelepipedus is an opportunistic carnivorous ground-beetle (Loreau, 1983) that inhabits the upper layer of litter in forest environments (Loreau, 1987).…”

13Large-scale Transportation Infrastructures (LTIs; roads, railways, etc.) are among the main de-14 terminants of landscape fragmentation, with strong impacts on animal dispersal movements and 15 functioning of metapopulations. Although the detection of the impacts of LTIs is now facilitated 16 by landscape genetic tools, studies are often conducted on a single specie, while it is acknowledged 17 that different species might react differently to the same obstacle. Multi-specific approaches are 18 thus required to get a better overview of the impacts of human-induced fragmentation, especially in 19 landscapes crossed by multiple LTIs whose impacts can accumulate. We surveyed two vertebrates 20 species (the grass snake Natrix helvetica and the midwife toad Alytes obstetricans) and two insect 21 species (the butterfly Maniola jurtina and the ground-beetle Abax parallelepipedus) in a landscape 22 fragmented by six LTIs: a motorway, a railway, a country road, a gas pipeline, a power line and a 23 secondary road network. Using multiple linear regressions and commonality analyses on both clas-24 sical and hierarchical genetic distances computed over reduced spatial scales, we showed that 38% 25 of the overall explained genetic variability across all species was due to LTIs. While the butterfly 26 was seemingly not impacted by any LTI, the genetic structure of the three ground-dwelling species 27 was mostly influenced by roads, motorway and railway. LTIs, and especially roads, mostly acted as 28 barriers to gene flow, barrier effects accounting for 85% of the overall variance in genetic distances 29 explained by LTIs across species. Although the power line did not affect any studied species and the 30 1 gas pipeline only impacted gene flow in the ground-beetle through forest fragmentation, other LTIs 31 systematically affected at least two species. Importantly, we showed that some LTIs could some-32 how promote gene flow, embankments probably providing favourable habitats for vertebrate species. 33Considering the high variability in species response to LTIs, we argue that drawing general conclu-34 sions on landscape connectivity from the study of a single species may lead to counterproductive 35 mitigation measures and that multi-species approaches are to be more systematically considered. 36
