“…The impact of grazing on soil urease activity can vary depending on several factors, including grazing intensity, season, and vegetation type [52][53][54]. Generally, grazing emerges as the primary factor directly affecting soil urease activity in the forest-steppe ecotone, as highlighted by the PCA-MLR (Figure 7).…”

Grazing impacts soil enzyme activities by changing soil conditions and microbial functions. Yet, the specific effects of grazing on soil enzymes in different northeastern China forest-steppe vegetation types remain poorly understood. To examine this, catalase (CA), urease (UA), and cellulase (CEA) activities were measured in different vegetation types (NS, MF, CP, GL) under both grazing and non-grazing conditions. Soil microbial biomass carbon and nitrogen (MBC and MBN) and other soil factors were also studied to gauge their impact on enzyme activities. The results indicated that enzyme activities were influenced by grazing, soil nutrient levels, mineralization, and microbial biomass carbon and nitrogen content. Grazing exerted the most significant influence on UA. CEA was predominantly affected by the content of biomass nitrogen and soil mineralization. CA, on the other hand, was primarily influenced by soil nutrient levels. Grazing influenced enzyme activities differently based on vegetation type. Under grazing, CA showed higher values in NS, MF, CP, and GL (4.09, 2.42, 3.26, and 3.90 mL 0.1 mol L−1 KMnO4 g−1 soil 20 min−1, respectively) with increases ranging from 32.52% to 505.00% (p < 0.05). Additionally, UA values were significantly higher in MF and CP (0.24 and 0.59 mg NH4+-N g−1 soil d−1, respectively) with increases of 66.67% and 156.00%, while UA and CEA were lower in GL, showing reductions of 78.79% and 166.67% (p < 0.05) (0.33 NH4+-N g−1 soil d−1 and 0.06 mg glucose g−1 soil 72 h−1, respectively) under grazing conditions. These findings underscore the importance of vegetation types in the grazing effects on soil enzymes at the forest-steppe ecotone and suggest that further efforts should be made to strengthen grassland grazing management to mitigate negative impacts on soil environmental health.

“…The hemipteran superfamily Hylicelloidea Evans, 1956, as the basal lineage of the clade Clypeata Qadri, 1967, is the ancestral group of all the three modern cicadomorphan lineages (i.e., froghoppers [Cercopoidea Leach, 1815], hair and singing cicadas [Cicadoidea Latreille, 1802], and treehoppers and allies [Membracoidea Rafinesque, 1815, s.l.]). To date, this superfamily is divided into four families: Hylicellidae Evans, 1956, from the upper Paleozoic to the Lower Cretaceous of Australia and Eurasia (Lambkin, 2020); Chiliocyclidae Evans, 1956, from the Triassic of Australia, and some fossils from Argentina with disputed systematic position (Lara and Bashkuev, 2020); Mesojabloniidae Storozhenko, 1992, from the Triassic of Kyrgyzstan, Argentina, and Australia (Lambkin, 2019; Lara et al, 2021); and Minlagerrontidae Chen, Szwedo, and Wang in Chen et al (2019a), exclusively recorded in the mid-Cretaceous Kachin amber of northern Myanmar (Chen et al, 2020). Among the four hylicelloid families, Hylicellidae, with ~15 genera ascribed to three subfamilies (Hylicellinae Evans, 1956, Vietocyclinae Shcherbakov, 1988b, and Conjucellinae Shcherbakov, 2012), was dominant and widespread from the Triassic to Early Cretaceous (Lambkin, 2019; Chen et al, 2020).…”

The extinct family Hylicellidae, as the ancestral group of modern cicadomorphans, had a wide distribution and a very high species-level biodiversity from the Triassic to Early Cretaceous. We herein report 11 new hylicellid specimens from the Jurassic Daohugou beds of Inner Mongolia, NE China, and execute geometric morphometric analysis (GMA) to elucidate their systematic position. Our GMA and subsequent morphometric statistics indicate that 10 of our new specimens can be compared to the holotype of Cycloscytina gobiensis, and one is new to science. Cycloscytina incompleta new species is erected based on this specimen, with the following discriminatory tegminal traits: C3 almost as long as and slightly narrower than C2, and the forking position of stem M distinctly migrates towards wing apex and much apicad of the stem CuA bifurcating. Additionally, Cycloscytina plachutai is herein transferred to the procercopid genus Procercopina, resulting in P. plachutai new combination. To date, just a few body structures of Hylicellidae have been revealed, and the new whole-bodied hylicellids reported herein provide some novel insights on the evolution of basal Clypeata. This study also emphasizes the use of morphometric analysis in the systematics of wing-bearing insects such as hylicellids. UUID: http://zoobank.org/84a67eba-9b7c-4e27-a436-764802c4cdfb.

Extant cicada (Hemiptera: Cicadoidea) includes widely distributed Cicadidae and relictual Tettigarctidae, with fossils ascribed to these two groups based on several distinct, minimally varying morphological differences that define their extant counterparts. However, directly assigning Mesozoic fossils to modern taxa may overlook the role of unique and transitional features provided by fossils in tracking their early evolutionary paths. Here, based on adult and nymphal fossils from mid-Cretaceous Kachin amber of Myanmar, we explore the phylogenetic relationships and morphological disparities of fossil and extant cicadoids. Our results suggest that Cicadidae and Tettigarctidae might have diverged at or by the Middle Jurassic, with morphological evolution possibly shaped by host plant changes. The discovery of tymbal structures and anatomical analysis of adult fossils indicate that mid-Cretaceous cicadas were silent as modern Tettigarctidae or could have produced faint tymbal-related sounds. The discovery of final-instar nymphal and exuviae cicadoid fossils with fossorial forelegs and piercing-sucking mouthparts indicates that they had most likely adopted a subterranean lifestyle by the mid-Cretaceous, occupying the ecological niche of underground feeding on root. Our study traces the morphological, behavioral, and ecological evolution of Cicadoidea from the Mesozoic, emphasizing their adaptive traits and interactions with their living environments.
