Geologic exploration for petroleum resources has created a network of linear clearings, known as seismic lines, that have altered the local hydro-climatological conditions within the ecosystems that they cross, including peatlands. Accordingly, understanding the interaction between human activities and hydrological fluxes in peatlands is crucial for identifying the processes sensitive to these types of disturbances, especially in a region with a subhumid climate. This study aims to assess the effect of seismic lines on evapotranspiration from the understory at different sites in northern Alberta. Actual evapotranspiration (AET) was measured using weighing lysimeters and chamber techniques, and potential evapotranspiration (PET) was calculated based on the Penman and Priestley–Taylor equation. Understory AET on the seismic lines was 59% and 33% higher than in the adjacent ecosystem, based on lysimeter and chamber measurements, respectively. Furthermore, we also observed that the soil temperature, available photosynthetically active radiation (PAR) and plant community composition were the primary drivers of the AET measured using chambers, while wind speed and PAR controlled the AET measured by lysimeters. We estimated that ground layer PET on the line was 51% higher than off the line. These variations affected the Priestley–Taylor coefficient of evaporability (<i>α</i>) values so that the <i>α</i> value on the seismic line (0.73) was higher than off the line (0.61). Accounting for transpiration from trees, it was determined that the AET from seismic lines exceeds the AET from adjacent areas by 31%. Considering the ubiquitous nature and high spatial density of seismic lines in the boreal region, these changes to a dominant water loss mechanism will have a considerable impact on hydrological fluxes and result in an altered water budget, with potential implications at the watershed scale.</p>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 6","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eco.70102","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927684","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}

The aim of our study was to disentangle the influence of aquatic habitat availability, aquatic habitat connectivity, and environmental conditions on the α-, β- and γ-diversity of phytoplankton, rotifers, microcrustaceans and macrophytes in shallow lakes from the Lower Paraná River floodplain. We conducted sampling campaigns during four hydrological conditions, including wet and extremely dry periods. We estimated the biodiversity of each biological group, assessed limnological conditions and calculated the availability and connectivity of aquatic habitats at both local (shallow lake) and landscape (floodplain) scales with active microwave Sentinel-1 and optical multispectral Sentinel-2 satellite data, combined with a geographic information system approach. To evaluate the influence of the studied variables on biodiversity, we applied generalised linear mixed models for α-diversity and a Mantel test for β-diversity. At the local scale, habitat availability and connectivity positively influenced overall α-diversity, while turbid and nutrient-rich conditions favoured phytoplankton but hindered microcrustacean α-diversity. At the landscape scale, β-diversity was more strongly associated with the heterogeneity of limnological conditions than with habitat connectivity, except for microcrustaceans, which were equally associated with both variables. Our study deepens the understanding of the main mechanisms of hydrology on the biodiversity of different biological groups and across spatial scales in the Lower Paraná River floodplain.

While restoration thinning likely affects soil moisture as well, it is unknown how significant or long-lasting such effects are. Especially little is known about the influence of thinning on root-zone soil moisture used by mature trees. In this study, we used 5 years of data from 126 soil water potential sensors to examine patterns in root-zone (25–100 cm) soil moisture in thinned and non-thinned dense ponderosa pine (<i>Pinus ponderosa</i>) forests as well as the edge areas (boundary) between them during 1–6 years post-thinning. We focused on the spring dry season and calculated three metrics: mean soil water potential, days to onset of soil drying and days spent under a critical drying threshold beyond which ponderosa pine experiences physiological drought stress. We found that thinned areas were consistently significantly wetter and spent less time under critical drying conditions than either non-thinned edge or non-thinned dense forest. Importantly, the thinned forest also experienced more consistent water availability compared to non-thinned forest, regardless of year-to-year precipitation variability. South-facing non-thinned edge areas dried earlier than either of the other treatments and may be especially vulnerable to drought.

This study uses the GAGES-II dataset (1981–2016) to examine relationships between environmental flow violations (EFVs) at stream gauges in the United States and characteristics of their upstream basins over two periods (1981–1998 and 1999–2016). The Variable Minimum Flow (VMF) approach was used to estimate environmental flows based on natural flow conditions for each hydrometric station. Basin characteristics were categorized into climate variability (precipitation and temperature changes), water withdrawals and geographical attributes. The variables representing these basin characteristics were then used as predictors or inputs to the random forest (RF) machine learning algorithm to analyse and predict temporal and spatial variations of EFVs based on the observed variations of predictors. The results of this study showed that approximately 55% of the 1625 stream gauges analysed exhibited EFV percentages exceeding 80% in both periods. Mapping these stations highlighted critical areas requiring intervention. Temporal EFV changes were assessed by comparing the two periods, and <i>K</i>-means clustering grouped stations into two clusters with distinct geographical and climatic characteristics. The RF models trained for prediction of average EFV differences between the two periods showed acceptable accuracy, with Kling–Gupta efficiency (KGE) values ranging from 0.5 to 0.7, although accuracy was higher in the stations in Cluster 2 covering more arid areas in the southwest. The feature importance analysis revealed that the dam storage-to-streamflow ratio (DSSR) and precipitation were key factors in humid areas (Cluster 1), while water withdrawal and temperature were more significant in arid areas (Cluster 2). A noticeable temporal shift was also observed as the relative importance of DSSR (water withdrawal) diminished (intensified) overtime. Given the large dataset and the diversity of factors considered, this methodology can be applied to the rest of the streamflow gauges in the United States, providing valuable insights for water resource management and environmental policy making.</p>\u0000 </div>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 6","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144915181","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}

To explore such dynamics, we developed a dynamical model for the changes of internal plant water storage (PWS) and soil moisture given a set of coupled balance equations. This trade-off was explored through the analysis of long-term plant fluxes over a range of climate regimes, providing constraints on water availability and demand while incorporating plant physiological mechanisms into the model framework. In conjunction, plant productivity was considered, taken as the plant carbon dioxide assimilation with an additional maintenance cost subtracted to account for varying internal plant water capacities. To explore these trade-offs analytically and characterize the long-term response to changing rainfall frequencies, a conceptual model was developed by linearizing the coupled ordinary differential equations (ODEs) governing PWS and soil moisture dynamics. This conceptual model produced clear PWS optima that decreased nonlinearly with increasing rainfall frequency, as plants with a higher PWS capacity maintained a higher minimum internal water storage overall. The model was then extended to include nonlinear components, including stochastic rainfall forcing. Under constant meteorological conditions, due to the cost associated with plant size along with the timescale of intake and water release, we found that net carbon uptake does not necessarily increase with larger maximum PWS capacities but is sustained for longer periods during drought due to transpiration being facilitated by internal water stores. This PWS reduces stress for water storing plants in climate regimes with high-intensity, low-frequency precipitation. Increased rainfall frequency and a decrease in intensity greatly reduce the overall optimal PWS capacity. Thus, the extended model confirms that optimal PWS decreases nonlinearly as the rainfall becomes more frequent and less intense, as in the conceptual model. This suggests that water storage plays a less critical role in wet environments that may show an increase in wet days, but not necessarily an increase in water availability. We then analysed remote sensing data trends in seasonally dry ecosystems and compared them with the nonlinear model to identify physically based mechanisms governing plant water use, identifying plant functional traits potentially coordinated with PWS.</p>","PeriodicalId":55169,"journal":{"name":"Ecohydrology","volume":"18 5","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eco.70078","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144910376","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}

We use the coho (<i>Oncorhynchus kisutch</i>) and Chinook (<i>Oncorhynchus tshawytscha</i>) salmon runs in Scott Valley, a 2 109 km² undammed rural watershed in northern California, USA, as a case study. Taking advantage of a nearly two-decade ecological monitoring dataset and long-term stream gauge measurements, we first examined hydrological–ecological correlations; then compared six different statistical modelling structures, using two techniques: LASSO and MARSS. In LASSO regressions, to balance the explanatory power of the models with the risk of overfitting, we used k-fold cross-validation to find the lowest error value of the tuning parameter lambda. In MARSS, we calculated models for each individual hydrologic metric and compared them using AICc values. Correlation coefficients indicate that hydrologic factors and spawner abundance both exert influence on juvenile fish production. Statistical models generally agreed that the hydrologic metrics with the highest coefficients are earlier river reconnection and greater fall flow magnitude during parents' spawning for coho, and lower wet season median flow and slower spring recession rate for Chinook (though this could change with additional years of data, especially for the smaller coho dataset). The influence of some metrics, notably fall flow difference from dry season, was positive or negative depending on the fish life stage in which the flow occurred.

Flow was found to mitigate the negative effect of deposited fine sediment on invertebrate communities in some instances. This was particularly the case for high antecedent flow metrics (e.g., high flows in the seven days prior to sampling).
