“…This suggests that such changes must be accompanied by changes at wider scales, notably at the landscape scale or even in a way that contributes to mitigate climate change. These results coincide with studies showing that landscape-level crop diversity enhance pest control (Redlich et al, 2018) and that some specific crop rotations considered at the landscape scale greatly influence carabid distributions within agricultural landscapes (Marrec et al, 2017).…”

Understanding effects on the huge diversity of cropping systems on local biodiversity is challenging but necessary to implement agroecological systems. Through a functional approach, the translation of cropping systems into resource and disturbance gradients is promising to decipher the relationship between cropping systems and biodiversity but has never been implemented for arthropods. To investigate contributions of resource and disturbance gradients arising from cropping systems vs environmental context (regional effect, meteorological conditions and landscape characteristics) on beneficial arthropod communities, we used a dataset collected in 60 crop fields from three French areas over a five-years period. It includes all farmers interventions, crop sequences, meteorological data, landscape composition and carabid samplings. We found that the environmental context contributed to about 75% of explained carabid variations on average, while resource and disturbance gradients contributed to about 25% of explained carabid variations. The resource and disturbance gradients were particularly important in winter and spring preceding the spring-summer period to determine carabid variations. Moreover, we identified thresholds above which resource and disturbance gradients start being beneficial or detrimental for carabids. For example, a Treatment Frequency Index above 2.07 in spring decreased the total activity density of carabids during the spring-summer period. Synthesis and application. While implementing for the first time a functional approach to understand the effects of different facets of cropping systems on arthropods, our study also allows us to identify periods and thresholds above which specific practices affect carabids. The identification of such thresholds can guide the provision of recommendations for policy, stakeholders and farmers about how to reduce cropping systems' impact on arthropods.

“…Crop habitat filtering was the highest in late spring, while it was almost inexistent in early spring. This seemingly random assembly of species in early spring can be explained by the fact that abundance-activity of carabid species in fields does not entirely depend on the present crop type, but mainly on the previous crop type(s) in the succession, and on the landscape context as carabid may colonize crops from nearby habitats at the onset of the growing season (e.g., Marrec et al, 2015, 2017). Because of crop rotation, farmlands are highly dynamic landscapes, both in space and time.…”

Trait-based community assembly studies have mostly been addressed along spatial gradients, and do not consider explicitly a fundamental dimension governing community assembly, the time. Nevertheless, such consideration seems particularly necessary in systems in which organisms have to face regular disturbances and rapid changes in vegetation phenology, such as in intensively managed farmlands. In this study, we aimed at understanding how the functional diversity of carabid beetle communities varied across the growing season in response to crop type. We tested three alternative hypotheses on mechanisms underlying the community assembly. We used data from a long-term monitoring conducted over nine years in an intensively-managed farmland in central western France, in a total of 625 fields. First, we measured morphological traits related to body size, dispersal mode, and resource acquisition on the 13 dominant carabid species (> 85 % of all trapped individuals) and identified three independent dimensions of functional specialization within our species pool along axes of a PCA and highlighted key traits for community assembly. Second, we evaluated the community assembly temporal dynamics and the impact of habitat filtering and niche differentiation in the different crop types with time, using linear mixed-effects models. We showed that functional species assembly of carabid beetle communities occurring in crop fields varies importantly intra-annually, with strong variations in these dynamics depending on crop type and crop phenology. Each crop acted as a filter on carabid communities for body size and resource-acquisition traits, and functional differentiation between crops increased with time. We did not find any evidence of habitat filtering on traits related to dispersal mode. Our results emphasize the major role of crop phenology but also disturbances involved by agricultural practices such as crop harvesting on changes in community assembly, likely due to seasonal and inter-annual redistributions of species in agricultural landscapes in response to such changes. The temporal dimension cannot be ignored to understand the assembly of local carabid communities in farmlands.

“…The study (Pajač Živković et al 2018) showed the positive effect of exclusion nets on A. dorsalis in an apple orchard of Croatia, thus confirming their value in assessing the introduction of new agricultural measures into practice. Marrec et al (2017) evaluated the impact made on activity and density of A. dorsalis by local crops, current year, landscape composition, and their interaction, and inter-annual changes in landscape composition due to crop rotations. Pitfall traps were installed in 188 fields in France, and the results revealed the beetle to be more abundant in oilseed rape and landscapes with a higher proportion of oilseed rape in the previous year.…”

Shifts in the bioclimatic range of Anchomenus dorsalis – specialized entomophage – were modeled in the MaxEntsoftware package and are presented on habitat maps. For the prediction, we used two climatic scenarios – mild (RCP2.6) and extreme (RCP8.5). Under the considered scenarios, the further warming would lead to shift and extension of the range to the north, northeast and east and decrease in the number of populations in the southern regions of Europe. The most important bioclimatic indicators which describe the geographic distribution of A. dorsalis are mean annual air temperature, mean daily amplitude of temperature for each month, overall amount of precipitations in the coldest quarter of the year, minimum temperature of the coldest month, mean temperature of the warmest quarter of the year, and annual amount of precipitations. Global warming causes the bioclimatic range of A. dorsalis to shift northeast and east in intracontinental territories, and west and northwest on islands. This species of ground beetle is an important object in monitoring of the condition of natural and agrarian ecosystems, sensitive to the growing global climate changes.  Poikilothermic animals may suffer from overheating, and even if they live far in the northern hemisphere, the ability of their organism to withstand increase in the environmental temperature is limited. Mild winters (with higher temperatures) may increase the mortality of A. dorsalis by exhausting their energy reserves.
