“…Immigration of carabids over water indicates that macropters dominate, even in drift material [ 70 , 71 ], suggesting that most drifting carabids are blown into the water from flight, and thus drift is less probable for large, flightless species. Our general observations of fewer flightless species on the islands are supported by other studies of carabids in freshwater systems [ 21 , 72 ] (but see [ 19 , 71 ]) and may result from occasional local extirpation on small islands with more infrequent re-colonization.…”

Life-history traits influence colonization, persistence, and extinction of species on islands and are important aspects of theories predicting the geographical distribution and evolution of species. We used data collected from a large freshwater lake (1,413 km2) in central Canada to test the effects of island area and isolation on species richness and abundance of carabid beetles as a function of body size, wing length, and breeding season. A total of 10,018 individual beetles from 37 species were collected during the frost-free period of 2013 using transects of pitfall traps on 30 forested islands ranging in area from 0.2 to 980.7 ha. Life-history traits improved the predictive ability and significantly modified the shape of species-area and abundance-area curves. Abundance and richness of small-bodied (< 13.9 mm), macropterous (winged), and spring-breeding species decreased with island area and increased with isolation. In contrast, richness and abundance of larger-bodied (> 14.0 mm) and flightless species increased with area, but not isolation. Body size of female Carabus taedatus Fabricius, the largest-bodied species, was positively related to island area, while body size on the adjacent mainland was most similar to that on smaller islands. Overall, species with large body size and low dispersal ability, as indicated by flightlessness, were most sensitive to reductions in area. We suggest that large-bodied, flightless species are rare on small islands because habitat is less suitable for them and immigration rates are lower because they depend on freshwater drift for dispersal to islands.

“…Carabid beetles are well suited to studies of island ecology and have been widely employed in this context [ 17 – 21 ]. Carabid dispersal is influenced by wing length and wing muscle development [ 22 – 25 ], thus effects of differences in dispersal ability on patterns of island occupancy can be studied [ 22 ].…”

“…This species is abundant in the forests of South Moravia (Šejnohová, 2006). The species dominates in the forests of Poland (Sklodowski, 2006(Sklodowski, , 2014Kwiatkowski, 2011;Sklodowski & Garbalinska, 2011;Zalewski et al, 2012). There numerous reports of finding this species in Lithuania (Tamutis et al, 2011).…”

Using geodata technology, we conducted a bioclimatic modeling of the spatial distribution of the common palearctic ground beetle – Pterostichus oblongopunctatus (Fabricius, 1787). The range of comfort of the territories included in this species’ range was obtained. We used the data on 510 sampling points, obtained as a result of the authors’ field surveys and the data base of the GBIF global fund of biodiversity and 19 climatic parameters from the WorldClim open base and MaxEnt program. The results determined the factors which have the greatest impact on the current distribution of P. oblongopunctatus. The main climatic factors affecting the distribution of P. oblongopunctatus are average annual temperature, average 24-hour amplitude of temperature over each month, average temperature over the driest quarter, average temperature over the warmest quarter of the year, total of precipitations in the driest month of the year. We performed a prediction of possible change in the range by two scenarios (RCP 2.6 and RCP 8.5) for 2050 and 2070. Using QGIS program, we estimated the areas of the species’ range, and compared them. According to the scenario RCP 2.6, by 2050, the range of the species will contract due to decrease in the territories with moderately continental climate, and by 2070, a restoration of the range would take place, for according to this scenario, the average annual temperature stabilizes. According to the scenario RCP 8.5, the range will contract by 2050 and will continue to decrease by 2070, for the concentration of CO2 continues to increase along with increase in average annual temperature. Climate changes can affect the life cycle of the beetle, its life expectancy and activity over the season. With changes in temperature, eggs and larvae of P. oblongopunctatus can be more vulnerable.

“…Dimorphic species in particular have been identified to be least threatened by fragmentation and species decline Barbaro and van Halder 2009;Nolte et al 2017). These species seem to benefit from a variable ecological strategy: during migration the number of individuals able to fly increases, which have a higher probability to successfully disperse and establish new populations, while under stable environmental conditions the number of flightless individuals increases, displaying higher fecundity and thus higher establishment abilities (den Boer et al 1980;Langellotto et al 2000;Zalewski et al 2012); also known as the oogenesis-flight syndrome (see Desender 2000). Macropterous species generally have a higher dispersal power and consequently better colonization and recolonization possibilities than brachypterous species (den Boer 1990).…”

Homburg for helping to complete and compile the species trait dataset, as well as two anonymous referees for their valuable comments on the manuscript. AbstractThe worldwide biodiversity crisis is ongoing. To slow down, or even halt future species loss it is important to identify potential drivers of extinction risk. Species traits can help to understand the underlying process of extinction risk. In a comprehensive study on 464 carabid beetle species, we used 2 ordinal logistic regression to analyze the relationship of species traits to extinction risk in Central Europe, taking phylogenetic relatedness into account. To consider varying trait responses in different habitat types, we also tested models for species groups associated with different habitat types (forest, open, riparian and wetland). Our results identified three traits of particular importance as predictors for high extinction risk: 1) high habitat specialization, 2) small distribution range size (which is not considered in the categorization of the German Red List), and 3) large body size. Furthermore, large macropterous species showed high extinction risk. Overall, species associated with mountainous, coastal and open habitats generally revealed a high risk of extinction, while most forest species showed a low extinction risk. However, forest species with predatory feeding behavior were threatened, as were wetland species that reproduce in autumn. Phylogenetic relatedness had no influence on how species traits predict carabid beetle extinction risk. In the light of these results, management and recovery plans for species which exhibit characteristic traits strongly associated with extinction risks, as well as the conservation and restoration of mountain, coastal and open habitats, have to be prioritized.
