Temporal changes in the spatial distribution of carabid beetles around arable field-woodlot boundaries

Abstract

Carabids are considered beneficial arthropods in agroecosystems, where they prey on crop pests or consume weed seeds. Therefore, knowledge of the spatial distribution of carabids in agricultural landscapes is crucial to efficiently manage the ecosystem services that they provide. In the present study, we investigated the spatial distribution of carabids around arable field-woodlot boundaries in different seasons: (1) early spring, (2) late spring, (3) summer and (4) late autumn. The spatial distribution of carabid abundance (activity-density) and species richness varied seasonally, and the total abundance was highest within arable fields, except in early spring when it peaked at the boundaries. The observed pattern was mainly driven by the spatial distribution of the open-habitat species, which aggregated near the field boundaries during winter and early spring. The open-habitat species penetrated into woodlots during the summer season but occurred almost exclusively outside woodlots in the other sampling periods. The abundance of the forest species was highest within woodlots with the exception of the early spring season, when their abundance peaked at the boundaries. Carabid species richness was highest within arable fields in close proximity to woodlot boundaries with the exception of the summer season, when the total species richness was similar across habitats.

Temperature effect on the temporal dynamic of terrestrial invertebrates in technosols formed after reclamation at a post-mining site in Ukrainian steppe drylands

“…To investigate the temporal dynamic in the abundance, species richness and species composition of invertebrate communities within the experimental polygon, animals were sampled using pitfall traps. The term "activity-density" is employed in some studies as this value is affected not only by population density but also by animal movement activity (Knapp et al, 2019). We investigated seven invertebrate groups closely associated with the soil environment or aboveground vegetation strata: (1) mollusks (Mollusca: Gastropoda), (2) spiders (Chelicerata: Arachnida), (3) millipedes (Myriapoda: Diplopoda), (4) centipedes (Myriapoda: Chilopoda), (5) terrestrial isopods (Malacostraca: Isopoda: Oniscidea); (6) insects (Tracheata: Insecta).…”

“…It is also important to note that several studies failed to find convincing correlations between the environment and the occurrence of spiders (Mallis & Hurd, 2005). The spatial distribution of carabids around arable field-woodlot boundaries was explored using logistic curves with the Huismann-Olf-Fresco models (Knapp et al, 2019). The species-specific effects of shrub cover on Arthropoda animal groups that act as indicators of degradation were revealed due to focusing on species niche breadths and optima (Hering et al, 2019).…”

“…In addition to habitat amount, landscape configuration strongly affects pests, enemies, and crop yield, though temporal dimensions remain largely under-explored (Haan et al, 2020). One robust finding across temperate agricultural landscapes is that habitat edges tend to support more diverse, abundant ground beetle (Roume et al, 2013;Duflot et al, 2017;Ng et al, 2018;Knapp et al, 2019) and spider communities (Öberg et al, 2007Royauté and Buddle, 2012;Mestre et al, 2018) in and around cereal fields, particularly early in the growing season. This observation demonstrates the contribution of semi-natural vegetation in patchy landscapes to overwintering habitat and timely recruitment of predators to crop fields (Bertrand et al, 2016;Gallé et al, 2018).…”

Scale-dependent environmental filtering of ground-dwelling predators in winter wheat and adjacent set-aside areas in Hungary

“…Although carabids and spiders are important ecosystem service providers (Bommarco et al 2013;Gagic et al 2017;Martin et al 2019), the effect of environmental filtering on them can vary depending on their functional traits. Utilizing a functional-trait based approach may provide better insight into the various processes in dynamic of agricultural landscapes than only considering taxonomic differences, such as species richness and/or abundance (Knapp et al 2019;Magura and Lövei 2019;Martin et al 2019). Whereas some functional traits, such as body size, wing morphology (as a proxy for dispersal) and habitat affinity (a proxy for fidelity) reflect environmental filtering through dispersal and their connection with feeding is indirect, hunting strategy is directly linked with the potential impact on pest populations (Schmidt-Entling and Döbeli 2009;Duflot et al 2014;Anjum-Zubair et al 2015;Gámez-Virués et al 2015;Gallé et al 2018Gallé et al , 2019Martin et al 2019).…”
