“…Due to their invertebrate faunas [83][84][85][86][87], riparian zones are extremely valuable for invertebrate conser-vation [88,89]. Our study and others have shown that woody riparian buffers are important habitat patches by providing food for terrestrial invertebrates (e.g., Cicadidae), sites for web construction (e.g., Tetragnathidae) and ambush-hunting (e.g., Thomisidae and Clubionidae), life-stage microhabitats and shelter (e.g., Culicidae), and sites for overwintering and laying eggs (e.g., Carabidae) [9,43,49,90,91]. Woody riparian buffers may provide essential habitat diversity (via plant diversity) that helps support diverse assemblages of riparian invertebrates (e.g., consumers) [81].…”

Stream and terrestrial ecosystems are intimately connected by riparian zones that support high biodiversity but are also vulnerable to human impacts. Landscape disturbances, overgrazing, and diffuse pollution of agrochemicals threaten riparian biodiversity and the delivery of ecosystem services in agricultural landscapes. We assessed how terrestrial invertebrate communities respond to changes in riparian vegetation in Romanian agricultural catchments, with a focus on the role of forested riparian buffers. Riparian invertebrates were sampled in 10 paired sites, with each pair consisting of an unbuffered upstream reach and a downstream reach buffered with woody riparian vegetation. Our results revealed distinct invertebrate community structures in the two site types. Out of 33 invertebrate families, 13 were unique to either forested (6) or unbuffered (7) sites. Thomisidae, Clubionidae, Tetragnathidae, Curculionidae, Culicidae, and Cicadidae were associated with forested buffers, while Lycosidae, Chrysomelidae, Staphylinidae, Coccinellidae, Tettigoniidae, Formicidae, and Eutichuridae were more abundant in unbuffered sites. Despite statistically equivocal results, invertebrate diversity was generally higher in forested riparian buffers. Local riparian attributes significantly influenced patterns in invertebrate community composition. Our findings highlight the importance of local woody riparian buffers in maintaining terrestrial invertebrate diversity and their potential contribution as a multifunctional management tool in agricultural landscapes.

“…Management of the organic matter input to the soil is key for maintaining soil quality and durable crop production. Soil organic matter (SOM) contributes to soil fertility and crop growth by numerous ways such as the binding and buffering of plant nutrients (Murphy, 2015), providing habitat and food for soil organisms (Sapkota et al, 2012;Aldebron et al, 2020), maintaining soil moisture (Lipiec et al, 2006) and improving the soil structure (Masri & Ryan, 2006;Simansky et al, 2013). Besides these functions, SOM is a form of carbon sequestration and is therefore important for mitigating greenhouse gas emissions (Lal, 2004;Iranmanesh & Sadeghi, 2019).…”

“…Strengthening these environmental features supports a more diverse array of flora and fauna (including arthropods) (Huston and Marland 2003, Welti et al 2017, Aldebron et al 2020, and this increased habitat complexity provides more niches, structure, resources, etc. that may have allowed the AMP arthropod community to maintain diversity while also absorbing higher numbers of S. invicta.…”

“…A keystone goal of AMP producers is to increase the resilience of an operation by bolstering various aspects of the environment, e.g., vegetation diversity, soil microbiota, soil physical properties, and water holding capacity (Teague et al 2011, Hillenbrand et al 2019). Strengthening these environmental features supports a more diverse array of flora and fauna (including arthropods) (Huston and Marland 2003, Welti et al 2017, Aldebron et al 2020), and this increased habitat complexity provides more niches, structure, resources, etc. that may have allowed the AMP arthropod community to maintain diversity while also absorbing higher numbers of S. invicta .…”

The red imported fire ant, Solenopsis invicta, is one of the most prolific invasive species to the Southeastern U.S. These invaders preferentially colonize highly disturbed land and grassland habitat. Management of livestock in pasture systems can have a profound impact on the level of disturbance in grassland habitats, and we hypothesized that pasture management would have a significant effect on S. invicta abundance in the Southeastern U.S., and arthropod diversity would negatively correlate with this invasive species. We studied the effects that pasture management systems (based on stocking density, rotation frequency, and insecticide application rates) have on fire ant mound abundance and arthropod diversity for the soil, foliar, and dung communities. S. invicta mounds were quantified and mound areas were documented along transect lines in six pastures. Soil and foliar arthropod communities were collected along the same transect lines, and dung communities sampled from pats within the pasture system. Pastures managed under adaptive multi-paddock (AMP) practices had 3.35× more S. invicta mounds and 4.64× more mound area than their conventionally managed counterparts. However, arthropod diversity did not correlate with S. invicta abundance for any of the three arthropod communities sampled. This study shows pasture management can have a significant impact on S. invicta mound abundance, but arthropod communities in AMP managed pastures did not suffer decreased diversity from increased abundance of S. invicta. Additionally, this study demonstrates that this invasive species does not necessarily contribute to diversity decline, at least under AMP pasture systems.
