Modelling the thermal requirements of these species is critical for projecting the impacts of climate change on forests and for developing appropriate adaptation strategies. Fitting models to phenological observations requires long time series of data, but such data are scarce. Researchers would benefit from combining databases from different locations to fit a single model. The aims of this study are to model the thermal requirements for flowering of the most relevant angiosperm tree species in central Europe and to determine if the accuracy of the models can be improved by limiting the geographic spread of the calibration data. To this end, we fitted the PhenoFlex phenology modelling framework using various subsets of records from the Pan-European Phenology database, which were paired with local temperature data. We used all available data for five species (<em>Acer platanoides, Alnus glutinosa, Betula pendula, Corylus avellana</em> and <em>Fraxinus excelsior</em>) to fit general thermal requirement models. We also fitted models using subsets of the dataset, limiting the calibration sets to data from climatically homogeneous regions and different geographical extents. The general models had average mean absolute errors of 8.51–15.15 days, indicating that they are effective in forecasting flowering onset for central Europe. Predictions did not improve when fitting models with data from temperature-homogeneous areas or from within small geographical extents. These findings suggest that fitting several models to cover parts of an extensive region does not necessarily perform better than fitting a single model for the whole region. This implies that including data from different locations within central Europe when calibrating models would increase the size of calibration datasets without causing a significant increase in model errors. This may help alleviate problems of data scarcity.</div></div>","PeriodicalId":50839,"journal":{"name":"Agricultural and Forest Meteorology","volume":"360 ","pages":"Article 110302"},"PeriodicalIF":5.6,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142609787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that: (i) ontogenetic growth trends of trees cause the radial growth rate to follow a typical unimodal pattern along the radius gradient.

In drylands, these organisms are known to thrive alone or coexisting with each other. Yet, how multiple combinations of biocrusts and vascular plants influence C cycling remains poorly understood. Here, we conducted a mesocosm field experiment in the Chinese Loess Plateau to investigate the influence of six contrasting microsites (bare soil, biocrust, shrub alone, shrub with biocrust, grass alone, and grass with biocrust) on ecosystem C fluxes, including changes in net ecosystem exchange (NEE), ecosystem respiration (<em>R</em><sub>e</sub>), and gross primary productivity (GPP). We also analyzed the influence of environmental factors (e.g., water and solar radiation) on ecosystem C fluxes across different microsites. Finally, the annual (2022.6–2023.6) NEE was simulated and estimated based on a random forest model to quantify the contributions (net C uptake or emissions) of biocrusts and vascular plants and their coexistence to C budgets in drylands. Our results showed that biocrusts and vascular plants largely regulate C fluxes in this dryland, and more importantly, that the manner in which these biotic components are combined, strongly influence the outcomes for C fluxes. In particular, we showed that microsites of biocrusts, vascular plants, and their coexistence increased GPP and <em>R</em><sub>e</sub> by 1.2–6.1, 1.5–56.2, and 1.1–50.0 times, respectively, compared to bare soil microsite. All these microsites supported a net C uptake (–0.31 to –10.84 μmol m<sup>–2</sup> s<sup>–1</sup>) except from bare soil, which was net C emission (+1.39 μmol m<sup>–2</sup> s<sup>–1</sup>). However, we also found that compared to vascular plant microsites, biocrust-vascular plant coexistence reduced NEE, <em>R</em><sub>e</sub>, and GPP by 21 %–29 % (closer to zero), 39 %–40 %, and 12 %–33 % respectively, suggesting some sort of competition among biotic components. Also, annual NEE was 37 %–159 % (closer to zero) lower at biocrust-vascular plant coexistence compared to biocrusts or vascular plants thriving alone. Correlation analysis results showed that temporal variation in C fluxes of biocrusts, vascular plants, and their coexistence were mainly driven by soil water content and photosynthetically active radiation. In summary, our work showed that vascular plants and biocrusts are key drivers of C cycling in this dryland, and further provide novel insights that considering the different biotic components of these drylands alone and in combination is critical to finetune our measurements for C fluxes in a context of climate change.</div></div>","PeriodicalId":50839,"journal":{"name":"Agricultural and Forest Meteorology","volume":"360 ","pages":"Article 110298"},"PeriodicalIF":5.6,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142601136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to delimit environmental regions with similar crop growth conditions and to identify the main climatic factors limiting rainfed maize yield, using the state of Kansas as a case study. For this purpose, databases encompassing the period from 1993 to 2021 period, including NOAA weather station data (<em>n</em> = 208), USDA county maize yield data, and crop phenology reports at the agricultural district scale, were compiled for analysis.

In this work, we examined whether there is genetic variation in DED resistance plasticity and the roles of tree growth, phenology and anatomical traits in plastic responses. We established two experimental plots with 12 <em>Ulmus minor</em> genotypes in two environmentally contrasting locations in Spain: Madrid, under an inland continental climate, and Valencia, under a coastal Mediterranean climate. We monitored growth and phenology detecting high plasticity in both traits. In the inland plot, genotypes were taller and showed a more synchronized phenology than in the coast. A first DED-pathogen inoculation was carried out 45 days after the average flushing date in each location, after which trees exhibited more symptoms inland. A second inoculation was carried out by dividing the coastal plot trees into early and late flushing trees and inoculating each group at 45 days after its average flushing date. Therein, susceptibility rose to a level close to the inland plot. In both inoculations, we detected a significant genotype-by-location interaction in DED resistance. The xylem anatomy revealed high plasticity and a significant genotype-by-location interaction in most traits. In the coastal trial, trees formed narrower vessels and stored more starch before inoculation. The synchrony of leaf phenology, higher growth rate, lower starch reserves and higher structural vulnerability of earlywood to DED possibly favored susceptibility in the inland plot.

Across all the 16 genera studied, a similar proportion of trees, 26.23 % and 25.73 %, exhibits rebound effect in the first year after weak and strong stresses, respectively. The amplitudes of growth rebound, measured as the difference between the mean of ring-width indices in the rebounding year and the subsequent eight years, are 0.242 and 0.266 after weak and strong stresses, respectively. Conifers generally rebound at a higher proportion but to a lesser amplitude than broadleaves. Furthermore, a higher proportion and greater amplitude of rebound were observed in trees having longer age and slower growth. Our findings provide a new perspective of tree resilience to disturbances and shed insights into the processes of forest recovery after growth suppressions.</div></div>","PeriodicalId":50839,"journal":{"name":"Agricultural and Forest Meteorology","volume":"359 ","pages":"Article 110285"},"PeriodicalIF":5.6,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142563269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
