Canonical correspondence analysis results indicated significant effects of total phosphorus, nitrite, dissolvent oxygen, electrical conductivity, bromate and boron on the distribution of macrophytes among streams, which was supported by results of the weighted average regression analysis. The IBMR indicated that the ecological quality status varied from bad to good in the studied streams. Deterioration in the water quality of a few ecosystems in the dry season compared to the rainy season was elucidated by the IBMR, which also distinguished the ecological conditions of streams. Results highlight that macrophyte species are one of the most important bioindicators to evaluate the ecological status of streams in Kahramanmaraş province due to their sensitivity to changes in environmental conditions.

By determining how meteorological variation leads to similar versus differing ecohydrological dynamics of forest and woodland ecosystems, we can gain insight on how future climate-driven declines may be realized. We characterized 23 mixed conifer forest (MC), ponderosa pine forest (PP) and piñon pine–juniper woodland (PJ) sites with different canopy covers in southern Nevada, USA. We compared meteorological variation between these sites and employed water balance modelling and information theory to estimate similarity in the density distributions of soil temperature (Ts), soil water potential (SWP) and transpiration partitioning into total evapotranspiration (T/ET) within and across ecosystems in wetter and drier seasons and in cooler and warmer decades. From 1941 to 2020, this location experienced declines in meteorological water deficit due to higher precipitation, although temperatures increased over more recent time periods (1981–2020). From 1981 to 2020, we generally found greater similarity in SWP and T/ET distributions within MC sites and PP sites in the cool season and in the warm season generally found greater similarity in Ts and T/ET distributions within and between PP and PJ sites (excepting T/ET between PJ sites and higher canopy cover PP sites). Recent warm decades promoted convergence in warm and cool season Ts dynamics, such that Ts dynamics generally became more similar between higher elevation MC sites and lower elevation PP–PJ sites. At the same time, warmer decades initiated divergence of SWP and T/ET dynamics within groups of MC–PP and PP–PJ sites that were formerly more similar to each other (excepting SWP in wet seasons). Although their dynamics will remain strongly coupled to precipitation, warming temperatures have the potential to promote divergence in the ecohydrological dynamics of ecosystems at lower and higher elevations in this sky island system and may also promote novel within-ecosystem divergence associated with variation in vegetation structural attributes.</p>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"17 7","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Grapevines are a valuable, long-lived species able to grow in hot and dry regions. We currently do not know whether rain-fed grapevines entirely rely on deep soil water or make substantial use of shallow water from summer precipitation events. Without knowing this, we poorly understand what fraction of summer precipitation inputs contributes to grapevine transpiration. This has implications for how we quantify grapevine-relevant precipitation budgets and for predicting the impacts of climate change on grape and wine production. We investigated grapevine water use in a vineyard in the Chianti region, central Italy. During the growing season of 2021, we monitored precipitation and soil moisture at 30- and 60-cm depth. We collected over 250 samples for stable isotope analysis from rainfall, soil, and plants. Since traditional plant water sampling is problematic for grapevines, we collected samples from shoots, leaves, and condensed leaf transpiration after sealed plastic bags were wrapped around a shoot. We use these alternative plant samples to reconstruct the isotopic signal in the xylem water and infer the plant's seasonal water origin throughout the growing season. The analysis of the seasonal origin of water revealed that, throughout the growing season, soil water and plant water received disproportional contributions by rain that had fallen in the winter, even when compensating for the Mediterranean climate of the area. Only in late summer did the grapevines use substantial amounts of summer rainfall, whose contribution occasionally became dominant. These results provide a better understanding of ecohydrological interactions and uptake dynamics in valuable socio-economic agroecosystems such as vineyards.</p>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eco.2711","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fish distribution data from 59 sites across 11 rivers of the Bhima River basin were collected, and pair-wise β<sub>Dissimilarity</sub> and site-wise local contribution to beta diversity (LCβD<sub>Sorensen</sub>) and its components (LCβD<sub>Turnover</sub> and LCβD<sub>Nestedness</sub>) were calculated. Power function regression was analysed to understand the decay in community similarity with geographical and environmental distances. Redundancy analysis was performed to investigate the relationship between fish distribution and environmental variables. Results indicated that species richness declined with increasing longitude from west to east. A negative relationship was observed between species richness and LCβD<sub>Sorensen</sub>. LCβD<sub>Turnover</sub> formed Ո-shaped curve at both ends of the species richness gradient, while LCβD<sub>Nestedness</sub> values exhibited Ս-shaped curve. No significant difference between mean LCβD<sub>Turnover</sub> and mean LCβD<sub>Nestedness</sub> across the sites was observed. The distance decay relationship between community similarity and both geographical and environmental distances follows the power law shape, and the slope of this relationship flattened with increasing distance. Precipitation, topography, temperature variation and dissolved oxygen played a pivotal role in shaping fish assemblages.

This study tests the hypotheses that <i>P. grandis</i> is using organic-rich soils that develop under their canopy and soil layering where organic soils contact carbonate sands as part of their water management strategy. We analysed the chemical and physical properties of soils from two atolls in the central Pacific Ocean, one wet (Palmyra, USA) and one dry (Nikumaroro, Kiribati). Additionally, we used HYDRUS-1D to simulate vadose zone water dynamics under a range of organic cap thicknesses (0, 14, 30 and 50 cm), precipitation intensities (1, 5 and 10 cm/h) and average precipitation amounts (50, 100, 200 and 400 cm/yr). Laboratory results indicate organic soils are strongly, though not exclusively, associated with <i>P. grandis</i>. Water holding capacity increases with soil organic carbon up to about 10% but not beyond that amount. Modelling results indicate significant water retained in organic soils where they overlie coarse carbonate sediments suggesting a capillary barrier development as the plant-mediated organic soil accumulates. Retained soil water extends modelled dry-down times of root-accessible soil by more than 3 weeks. This indicates that capillary barrier-enhanced water availability can help explain how <i>P. grandis</i> and other soil-building atoll species can exist across variable precipitation regimes.

The study systematically analyse the process of keyword changes and research hotspots in Chinese and international English literature, providing a detailed explanation of the differences in research hotspots and the reasons for their formation. The research indicates that since the inception of the term ‘ecohydrology’, relevant literature has displayed sluggish growth alongside rapid development. Additionally, alterations in primary keywords have differed between Chinese and English literature over time. However, ‘groundwater’ has consistently retained a significant amount of attention within Chinese literature. Groundwater has been extensively studied in Chinese literature, with a particular focus on eco-hydrological processes, their effects, modelling and techniques. Similarly, English language literature is abundant with keywords denoting pivotal concepts like the environment, hydrology, fauna and rivers. These areas have been the focal points of research for international scholars. Regional characteristics, ecological conditions, economic development level and scientific research priorities, among other factors, are all significant contributors to the development of the field of ecohydrology. Differences in research hotspots can also be attributed to geographical characteristics, ecological environment conditions and scientific research priorities. Over the past decade, there has been a gradual convergence in research between Chinese and English literature. The current hotspots of research in ecohydrology include basic research, theoretical applications and adaptive wide-area mechanistic research.
