Effects of Different Harvest Times on Nutritional Component of Herbaceous Peony Flower Petals by Weixing Li, Xiaomei Song, Yanmin Hua, Jun Tao, Chunhua Zhou

“…Herbaceous peony (Paeonia lactiflora Pall.) flowers can be used as edible flowers, but few studies concerned about their edible values and the optimal harvest season. In this study, petals of three herbaceous peony cultivars including “Dafugui,” “Hongyan Zhenghui,” and “Yangfei Chuyu” at four different development stages were used as materials to measure the content of soluble sugar, organic acid, protein, vitamin C (Vc), total phenolics, total flavonoids, mineral elements, and superoxide dismutase (SOD) activity, with the aim to understand the variation tendency of the nutritional ingredients and bioactive components in herbaceous peony flower petals during development and to determine the optimal harvest time for herbaceous peony flowers with better edible qualities. …”

Different nitrogen uptake patterns of plant and soil microorganisms in the forest-grassland transition zone on the Loess Plateau by Lina Wang, Xu Deng, Ying Zhou, Xueqi Geng, Zeling Zhang, Yakun Tang

“…IntroductionIt is unclear whether plants and microorganisms achieve niche complementarity by taking up different inorganic nitrogen (N) forms to alleviate N competition, particularly in N–limited regions.MethodsThis paper conducted a 15-day 15N tracer study (15NH4NO3 or 15NH4NO3) in situ to quantitatively calculate the uptake rates of plants and microorganisms in four stands (pure Hippophae rhamnoides L, pure Pinus tabuliformis Carrière, mixed H. rhamnoides–P. tabuliformis, and Artemisia gmelinii Weber ex Stechm grassland) in the forest–grassland transition zone on the Loess Plateau during the growing season. Among them, H. rhamnoides and P. tabuliformis can associated with arbuscular mycorrhizal and ectomycorrhizal, respectively.ResultsThe results indicated that H. rhamnoides in the pure stand and A. gmelinii preferred to take up 15NO3–, whereas P. tabuliformis in the pure stand preferred 15NH4+. …”

Extent of spike shedding and stem wilting of pepper (Piper nigrum L.) in Morogoro District, Tanzania by Abdul Jafari Shango, Ramadhani Omari Majubwa, Amon Petro Maerere

“…Approximately 53% of respondents reporting the disorders used Jatropha to support the pepper vines, and 93% of the farmers reported the disorders to occur during the dry season. A greater proportion of the interviewed farmers (92.1%) reported applying no measures to control spike shedding and stem wilting of pepper. …”

Resource availability and competition shape pollinator trophic specialization in longleaf pine savannas by Pablo Moreno-García, Johanna E. Freeman, Benjamin Baiser, Joshua W. Campbell, Daijiang Li

“…We used samples collected over an entire flowering season in 24 xeric pine savannas in north-central Florida, USA and evaluated the effects of plant availability and pollinator competitor pool on three aspects of trophic specialization: taxonomic specialization (pollinator selection of plant species), phylogenetic specialization (pollinator selection of plant phylogenetic lineages), and functional specialization (pollinator selection of plant functional traits). …”

Wastewater-based estimation of temporal variation in shedding amount of influenza A virus and clinically identified cases using the PRESENS model by Hiroki Ando, Michio Murakami, Masaaki Kitajima, Kelly A. Reynolds

“…In this study, we applied two mathematical models to previously collected wastewater and clinical data from four U.S. states during the 2022/2023 influenza season, dominated by the H3N2 subtype. First, we modeled the relationship between the detection probability of IAV in wastewater and FluA case counts, using a logistic function. …”
