With turfgrass being a crop of economic and ecological importance, management of pests attacking this crop should encourage the conservation of other beneficial invertebrates in the ecosystem. Thus, our objective was to quantify and compare the abundance of beneficial arthropod groups across turfgrass stands at three cover levels (0 %, ∼50 %, and 100 % cover) representing early, intermediate, and fully established sod. We hypothesized that beneficial arthropods would be less abundant in early-stage (sparse cover) sod than in fully covered turf, due to reduced habitat and resources at early stages. In 2021 and 2022, zoysiagrass (<em>Zoysia</em> spp.) sod fields with 0 %, 50 %, and 100 % turfgrass cover were selected, and arthropod abundance was documented using pitfall traps. The numbers of carabids, staphylinids, and parasitic hymenopterans in 2021 and the parasitic hymenopterans in 2022 were less abundant in turfgrass at the early stages of development. However, dermapterans were more abundant in the turfgrass at the early stages of development than fully covered. The abundance of Araneae increased when the turfgrass fully covered the ground. Although beneficial arthropods were prevalent at all stages of turfgrass development, they were less abundant at the early stages.

Studies predominantly focused on the Hymenoptera order and seed production. There were no consistent effects on pollinator richness, abundance or visitation nor on flower production; the significant effects, when observed, were mostly due to single influential papers. Our findings underscore the growing attention to this topic but highlight significant research gaps, particularly in tropical regions and concerning non-Hymenoptera pollinators. Additionally, although there is no consistent evidence, it is possible that edges boost pollinator abundance and visitation while simultaneously reducing fruit and/or seed production.

First, to quantify use and availability, we measured vegetation at the locations used by deer during May–June 2022, as well as in the general environment, then applied principal components analysis (PCA) to capture the major gradients in vegetation conditions. Second, to identify habitat selection, we tested for differences between use and availability in both the means and variance of vegetation characteristics. Finally, to depict how variance changed across scales, we constructed spatial and temporal variograms. Based on the first two axes of the PCA, we found that deer selected greater abundance in forage and lower variation in canopy closure. Across space, the selection for reduced variance in canopy appeared largely independent of scale (50–1000 m), implying that the perception capacity of deer may exceed this range. Across time, deer exhibited rising variance in forage abundance at short lags (4–12 h), resembling the periods (6–10 h) when movements were more linear. Deer thus selected for lower variance of habitat without selecting for disproportionate levels of habitat. We propose that selection for diminished variance is a fundamental property of habitat selection, whose scale-dependence might be uncovered with geostatistics.</div></div>","PeriodicalId":55564,"journal":{"name":"Acta Oecologica-International Journal of Ecology","volume":"128 ","pages":"Article 104103"},"PeriodicalIF":1.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144563551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review aims to assess the current status of IAPS, its impact on ecosystems and ecosystem services, and management efforts to maintain its distribution in South Africa. Various studies indicate that IAPS distribution is increasing at an alarming rate in South Africa. South Africa is home to many IAPS and the country is categorized as one of the most affected countries in the world. IAPS also have significant impacts on water resources of the country, rangelands quality (lowering the grazing potential), and soil health. IAPS generally create major impacts on the delivery of ecosystem services. Although considerable efforts have been made so far, IAPS continue to negatively impact the country's biodiversity and socioeconomics.
