“…Legacies of heavy metal contamination in urban soils are a consequence of past industrial manufacturing, smelting, and waste disposal, as well as widespread use of products such as leaded gasoline and lead‐based paints (Pouyat et al 2010, Wortman and Lovell 2013). Exposure to elevated levels of heavy metal pollutants in urban soils can have reproductive (Hendrickx et al 2003, Lagisz and Laskowski 2008), developmental (Scheifler et al 2002, Lagisz 2008, Cheruiyot et al 2013), immunological (Stone et al 2002, Migula et al 2004, Sorvari et al 2007), and behavioral (Eraly et al 2009, Sorvari and Eeva 2010) impacts on arthropods, including ground‐dwelling predators that experience direct and indirect exposure (Gardiner and Harwood 2017). Contamination of vacant lot soils by heavy metals was identified as a local environmental stressor for ground‐dwelling beetle communities in this study, with more functionally similar beetle communities found in highly contaminated vacant lots.…”

Community assembly is the process by which local communities are organized and maintained from the regional species pool. Understanding processes of insect assembly are of interest in "shrinking" cities where vacant land has become abundant as a result of protracted economic decline and population loss. Vacant land represents a viable conservation space for insects such as beetles that contribute to ecosystem services including pest suppression, decomposition, and nutrient cycling. However, the inherent heterogeneity of cities may pose challenges for beetle dispersal from source populations, while quality of the urban environment may constrain establishment. The objective of this study was to investigate the constraints to ground-dwelling beetle community assembly in vacant lots and pocket prairies of Cleveland, Ohio using a functional trait-based approach. Functional traits with a strong predictive capacity for ecological functions were measured on beetle species collected via pitfall traps. Assembly of beetle communities was primarily constrained by dispersal limitations to colonization. Over 93% of species found within treatments were capable of flight, and functional diversity of beetle communities was higher across all treatments than expected by chance. Once beetles colonized, successful establishment was influenced by heavy metal contamination and mowing frequency, with these disturbances shaping communities based on body size, antennae length, and origin. Colonization of dispersal-limited species could be facilitated by increasing connectivity among greenspaces in cities, while establishment could be enhanced by managing local environmental conditions. Understanding how insect communities are structured in urban ecosystems provides context for observed patterns of biodiversity, advances conservation efforts, and fosters ecosystem services.

“…For example, increased evapotranspiration, such as in Madison, WI, USA [22], is influenced by soil moisture and urban warming, and may play a significant role in tree physiology [108][109][110], condition and herbivory [55,73]. Simultaneous measurement of climate variables and urban variables such as land cover, population density and impervious surface is crucial in addressing confounding factors associated with urban environments, such as air quality [65,66], water or soil pollution [111][112][113][114], soil compaction and invasive species [115][116][117]. Understanding the potential for acclimation or adaptive evolution by urban species (and the potential for non-adaptive genetic drift and gene flow) is also important in validating cities as surrogates for global change.…”

Urbanization represents an unintentional global experiment that can provide insights into how species will respond and interact under future global change scenarios. Cities produce many conditions that are predicted to occur widely in the future, such as warmer temperatures, higher carbon dioxide (CO) concentrations and exacerbated droughts. In using cities as surrogates for global change, it is challenging to disentangle climate variables-such as temperature-from co-occurring or confounding urban variables-such as impervious surface-and then to understand the interactive effects of multiple climate variables on both individual species and species interactions. However, such interactions are also difficult to replicate experimentally, and thus the challenges of cities are also their unique advantage. Here, we review insights gained from cities, with a focus on plants and arthropods, and how urban findings agree or disagree with experimental predictions and historical data. We discuss the types of hypotheses that can be best tested in cities, caveats to urban research and how to further validate cities as surrogates for global change. Lastly, we summarize how to achieve the goal of using urban species responses to predict broader regional- and ecosystem-level patterns in the future.

“…Work on different aspects of populational diversity on genetic (Siepel, 1988;Den Boer et al, 1992;Lagisz et al, 2010) and morphological (Emetz, 1986;Schwerk & Jaskuła, 2018) levels allow one to state that P. oblongopunctatus is one of the best studied species of ground beetles. P. oblongopunctatus is a typical element of urban forest plantations and anthropogenically transformed territories (Grechanichenko & Guseva, 2000;Magura et al, 2008;Gardiner & Harwood, 2017). Thus, the studied species of ground beetle is a practical object for modeling changes in the range in conditions of global climate changes, one of the priority factors which affects natural populations in XXI century (Kotze 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.
