“…For studies aiming to describe the arable land system landscape structure, we propose metrics that reveal more information about connectivity, fragmentation, and diversity, such as contagion index, patch richness density, and Shannon's diversity index, as they jointly reflect how a given matrix facilitates or hinders migration and re-colonization of habitat patches or remnants [56]. In this study, the relationship between the diversity of epigaeic arthropods and landscape structure in the northern plains was found at different landscape scales, which supported the previous study [57].…”

Understanding the multi-scale effects of arable land landscape on epigaeic arthropod diversity is essential for biodiversity conservation and agroecosystem services. Our study explored the overall effect of landscape elements on epigaeic arthropod diversity at three scales of landscape, habitat, and field. We selected 11 areas to sample using the trap method, and construct models of landscape elements and biodiversity data. The results showed that: (1) On the landscape scale, 1500 m was the optimal radius. Shannon’s diversity index and interspersion and juxtaposition index can explain the diversity of epigaeic arthropods at the level of 76.7%. (2) On the habitat scale (the radius less than 100 m), habitat types significantly affected the species number, Pielou evenness index, and individual number of epigaeic arthropods (p < 0.05). The distribution of epigaeic arthropods had an obvious margin effect. (3) On the field scale, we also revealed The Shannon diversity index and Pielou evenness index of herb vegetation structure can explain the change of epigaeic arthropod community structure at the level of 69.1%. We believe that an appropriate scale is the best lever to protect agricultural biodiversity. Our research can promote multi-scale integrated conservation of regional biodiversity and sustainable development of agricultural systems.

“…For example, the seasonality of weather patterns can affect the emergence, growth, dispersal and reproduction of some surfaceactive arthropods (Pinheiro et al 2002;Bowie et al 2014). In particular, leaf beetles (Chrysomelidae) and ground beetles (Carabidae) are active in the wet season and find shelter under debris, rocks and leaf litter where they overwinter to escape the cold and harsh climatic conditions that come with the dry season (Bj€ orkman & Eklund 2006;Gall e et al 2018;Pizzolotto et al 2018;Hoffmann et al 2021). As such, weather patterns may play an important role in driving the assemblages of surface-active arthropods.…”

“…Influences of the seasonal activity of surfaceactive arthropods are complex and interconnected (Pinheiro et al 2002;Anjos et al 2016;Tembe & Mukaratirwa 2020), making it difficult to separate and test these factors independently. Several studies have investigated the effect of season on arthropod activity and abundance (Pinheiro et al 2002;Suheriyanto et al 2019;Marquart et al 2020;Hoffmann et al 2021). However, most studies focus on single groups and not much work has been carried out on the collective response of various arthropod groups.…”

Preliminary patterns of seasonal changes in species composition of surface‐active arthropods in a South African savannah

et al. 2022

Surface‐active arthropods have limited dispersal abilities and their abundances are responsive to changes in the environment. Their sensitivity allows for the identification of aspects of environmental variation that are responsible for changes in community assemblages of these arthropods. Limited dispersal abilities allow for changes in the populations of surface‐active arthropods to be linked reliably to changes in their local environment. In this study, we tested the hypothesis that seasonal variation in resource availability drives assemblages of three groups of surface‐active arthropods (ants, beetles and spiders). Ten study sites were selected, where sampling was carried out continually during the wet, austral summer season (December 2018–February 2019) and then repeated at the same sites in the dry winter season (June 2019–August 2019) in a mesic savannah of Mpumalanga province, South Africa. Pitfall trapping was used to sample the surface‐active arthropods. We found 89 morphospecies of ants, 48% of which were members of the Myrmicinae, while 32% of the 163 morphospecies of beetles were the Scarabaeidae. There were 262 morphospecies of spiders, of these, 22% were from the Salticidae. We found similar abundance and species richness of ants between seasons but significantly greater abundance and species richness of beetles and spiders in summer than in winter. These results show that the impact of seasonal variation in resource availability differs among arthropod taxa. However, the species compositions of all three taxa were significantly different between summer and winter. These results can be explained by the ‘niche differentiation hypothesis’ coupled with the ‘resource‐ratio hypothesis’. Additionally, these results highlight the role that temporal and dietary niche differentiation play in driving the assemblage composition of surface‐active arthropods in a mesic savannah.

“…Agricultural landscapes may contain a variety of refuge habitats spanning from near-natural, like kettle holes (Platen et al 2016), forest patches (Fournier and Loreau 2001) to novel, anthropogenic habitats, like grasslands around wind turbines (Pustkowiak et al 2018). Since particular properties differ between habitats, like habitat age, habitat complexity and disturbance intensity, habitats may harbor on the one hand different carabid species (Hoffmann et al 2021;da Silva et al 2008;Fairchild et al 2000), but may also modulate the impact of land-use intensi cation on carabids in the respective habitats. For instance, dispersal limitation of non-arable species may be particularly strong in novel habitats, since species had less time to colonize new patches.…”

The increase of agricultural fields leads to habitat loss and fragmentation of (semi-)natural habitats (SNHs) that provide refuge sites for a variety of taxa. Carabid beetles are reliable biodiversity indicators and provide important ecosystem services in agricultural landscapes. However, it still remains unclear how carabid beetles inhabiting SNHs respond to increasing arable field cover as a measure of land-use intensification. We predict that the relationship between arable field cover and carabid beetle abundance and species richness is specific to habitat type and species ecology. We tested our predictions in an intensively used agricultural landscape in northeast Germany and sampled carabid beetles at two different insular SNHs within arable fields: grassland patches of wind turbines (novel SNH) and kettle holes (natural SNH). Our multi-spatial-scale analyses revealed that with increasing arable field cover the proportion of arable species increases for both SNH types. However, we found contrasting relationships in species richness and abundance between the SNHs. At the grassland patches around wind turbines, arable field cover negatively affected arable species´ richness and abundance as well as non-arable species´ richness. In contrast, at kettle holes, arable species richness and abundance increased with arable field cover, while non-arable species were not affected. In summary, our study demonstrates that the effect of land-use intensification on carabid beetles is highly dependent on the specific habitat type and species ecology. Our findings highlight the importance of habitat type for managing SNHs within agricultural landscapes while improving our understanding of how land-use intensification affects carabid beetle diversity.
