“…However, due to the changes in prey abundance, the food source of Araneae changes throughout the year ( Edgar 1969 , Symondson et al 2002 , Saska et al 2013 ). In addition, Araneae are known to respond to environmental changes, and some species are highly sensitive to small changes in habitat structure and microclimate factors ( Buddle et al 2000 , Marc et al 1999 , Pearce and Venier 2006 , Reyes-Maldonado et al 2018 , Maelfait 1996 , Honek 1988 , 1997 ). The NMDS results in this study give insights into the impact of cover crop biomass over time on Araneae activity and its relationship with possible prey.…”

Relative to fallow-cash crop rotations, the addition of a cover crop can contribute to greater plant diversity and has the potential to conserve predatory arthropods. The transition of arthropods from a cover crop to a subsequent cash crop depends on several factors, such as cover crop biomass production and weather conditions. Information about the effect of cover crop planting and termination dates on arthropods in a subsequent corn system is limited. A two-year field study was conducted in Nebraska in 2018/2019 and 2019/2020 to evaluate the impact of cover crop planting and termination dates as a source for arthropods in the subsequent corn. A total of 38,074 and 50,626 arthropods were collected in the first and second year, respectively. In both years, adding a grass cover crop increased predatory arthropods but reduced yield in follow corn crop. Of the arthropods collected, Carabidae and Araneae had greater activity with cover crop biomass increments, whereas Collembola and Acari activity only increased in treatments with little or no cover crop biomass. Insect pest pressure was not significant in any treatment for either year. A cover crop planted in mid- or late-September and terminated at corn planting was identified as the best management strategy to maximize cover crop biomass, increase predator activity, and modify predator-prey dynamics. The results of this study provide growers with a cover crop management strategy to maximize cover crop biomass, beneficial arthropod activity, and potentially minimize insect pest problems; however, corn Zea Mays (L.) grain yield was reduced as cover crop biomass increased.

“…Spiders have occasionally been used as bioindicators, and in recent years some studies have underlined their potential as good bioindicators [115,116]. First, they are characterised by great taxonomic diversity and abundance in both natural and cultivated environments, with average annual abundance ranging from 50 to 150 individuals per square meter [117].…”

The dramatic increase in soil degradation in the last few decades has led to the need to identify methods to define not only soil quality but also, in a holistic approach, soil health. In the past twenty years, indices based on living communities have been proposed alongside the already proven physical-chemical methods. Among them, some soil invertebrates have been included in monitoring programs as bioindicators of soil quality. Being an important portion of soil fauna, soil arthropods are involved in many soil processes such as organic matter decomposition and translocation, nutrient cycling, microflora activity regulation and bioturbation. Many studies have reported the use of soil arthropods to define soil quality; among taxa, some have been explored more in depth, typically Acari and Collembola, while generally less abundant groups, such as Palpigradi or Embioptera, have not been investigated much. This paper aims to evaluate and compare the use of different soil microarthropod taxa in soil degradation/quality studies to highlight which groups are the most reported for soil monitoring and which are the most sensitive to soil degradation. We have decided not to include the two most present and abundant taxa, Acari and Collembola, in this paper in consideration of the vast amount of existing literature and focus the discussion on the other microarthropod groups. We reported some studies for each taxon highlighting the use of the group as soil quality indicator. A brief section reporting some indices based on soil microarthropods is proposed at the end of this specific discussion. This paper can be considered as a reference point in the use of soil arthropods to estimate soil quality and health.

“…Tetragnatha play crucial roles in riparian ecosystems as the primary predators of insects emerging from aquatic larval stages ( Okuma 1968 ; Barrion and Litsinger 1984 ) and as a source of prey for other predatory taxa, notably birds ( Gunnarsson and Wiklander 2015 ). Both their integral nature in riparian communities and their sensitivity to changes in water availability make them important bioindicators ( Reyes-Maldonado et al . 2017 ).…”

Climate-driven changes in hydrological regimes are of global importance and are particularly significant in riparian ecosystems. Riparian ecosystems in California provide refuge to many native and vulnerable species within a xeric landscape. California Tetragnatha spiders play a key role in riparian ecosystems, serving as a link between terrestrial and aquatic elements. Their tight reliance on water paired with the widespread distributions of many species make them ideal candidates to better understand the relative role of waterways versus geographic distance in shaping population structure. To assist in better understanding population structure, we constructed a reference genome assembly for T. versicolor using long read sequencing, scaffolded with proximity-ligation Omni-C data. The near-chromosome-level assembly is comprised of 174 scaffolds spanning 1.06 Gigabase pairs, with a scaffold N50 of 64.1 megabase pairs and BUSCO completeness of 97.6%. This reference genome will facilitate future study of T. versicolor population structure associated with the rapidly changing environment of California.
