Frogs and flows: Using life-history traits and a systematic review to establish water-dependent functional groups for stream frogs in New South Wales, Australia Ecohydrology (IF 2.6) Pub Date : 2024-03-18 Daniel W. Coleman, Rebecca J. Wood, Michael Healey
Hydrological alteration has contributed to the global decline of stream frogs. Flows support stream frog reproduction, juvenile development, food resources, and maintain habitats for all life stages. At present, there is a lack of information regarding the specific water requirements necessary for the conservation of stream frogs. To address this gap, we developed a traits-based approach that serves

δ2H isotopic offsets in xylem water measurements under cryogenic vacuum distillation: Quantifying and correcting wood‐water hydrogen exchange influences Ecohydrology (IF 2.6) Pub Date : 2024-03-16 Seth E. Younger, John Blake, C. Rhett Jackson, Doug P. Aubrey
Stable isotopes δ18O and δ2H are used to infer vegetation water sources. In some studies, significant xylem water δ2H offsets from potential source waters have been observed. The offsets appear to be more prevalent with cryogenic vacuum distillation (CVD) of plant water. Hypothesized mechanisms for these offsets include changes during plant water uptake and transport, and methodological problems. We

Impacts of vegetation dynamics on hydrological simulations under drought conditions in a humid river basin in Southern China Ecohydrology (IF 2.6) Pub Date : 2024-02-27 Cancan Liu, Yongqin David Chen
Vegetation plays an essential role in the atmospheric and hydrological processes, and vegetation responds differently to climate change in various regions, especially in extreme climates. Therefore, the use of static prescribed vegetation information from past years in numerical models can be a source of biases in hydrological simulations. However, previous studies have mainly focused on the effects

Hayes
Unnatural changes in river flow patterns resulting from peak-operating hydropower plants adversely impact freshwater ecosystems. In particular, the rapid dewatering of shoreline habitats during artificial flow down-ramping puts early fish life stages at a high risk of becoming stranded if they fail to follow receding water levels in time. While extensive research has been conducted on the effects of

Fish stranding in relation to river bar morphology and baseflow magnitude: Combining field surveys and hydrodynamic–numerical modelling Ecohydrology (IF 2.6) Pub Date : 2024-01-26 Daniel S. Hayes, Christoph Hauer, Günther Unfer
Hydropeaking mitigation based on down-ramping thresholds is crucial to avoid stranding of fish and ensure sustainable hydropower production. However, the risk of stranding is influenced by several biotic and abiotic factors that interact with the ramping rate, including river morphology and baseflow magnitude. Also, at the river bar scale, the lateral or horizontal down-ramping velocity may be of even

A false paradigm? Do biocrust types necessarily reflect ‘successional stages’? Ecohydrology (IF 2.6) Pub Date : 2023-12-13 Giora J. Kidron, Bo Xiao
The term ‘succession’ was first proposed to describe the gradual development of plants from an initial stage such as a bare ground to a well-developed plant community, which at its peak, may reach a climax (primary succession). Accordingly, the earlier and fast growing stage (such as an annual plant community) may grant stability, organic matter and nutrients to the latter, high-biomass and slow-growing

An inconvenient trend: Decadal decline in ground height of swamps in Southern Illinois Ecohydrology (IF 2.6) Pub Date : 2023-09-14 Beth A. Middleton
An understanding of the long-term trends of ground height and sedimentation in a landscape context can provide a framework to better understand the impacts of agricultural development on floodplain processes. This study examined long-term changes in ground height using surface elevation tables (SETs) and sediment deposition measurements in the Cache River floodplains of Southern Illinois including

Testing transpiration rates of juvenile Aleppo pine trees using the heat ratio method under laboratory conditions Ecohydrology (IF 2.6) Pub Date : 2023-09-13 Ana M. Sabater, José Antonio Valiente, Juan Bellot, Alberto Vilagrosa
Tree transpiration considerably contributes to evaporative fluxes to the atmosphere in terrestrial ecosystems. Accurate transpiration quantification provides relevant information about forest water use and may benefit adaptive forest management, especially in a global change context. Tree transpiration can be measured by several methods, and sap flow measurements are one of the most valued. However

Identification of driving factors for chlorophyll-a in multi-stable shallow lakes of China employing machine learning methods Ecohydrology (IF 2.6) Pub Date : 2023-09-12 Shan Qu, Jian-jian Wang, Amit Kumar, Zhi-Guo Yu, Wan-Qi Zhao
Due to the rapid increase in urbanization and anthropogenic activity in the lake catchment, nutrients like phosphorus and nitrogen are abundant in urban sewage, leading to lake eutrophication and promoting algal blooms. Chlorophyll-a (Chl-a) is an important indicator of algal blooms; thus, predicting concentration is vital for lake restoration and management. Literature reveals that most of the previous
