“…To a certain extent, our analysis probably has also been biased by assigning adult traits to populations with variable growth stages. This can be problematic for woody pioneer Salicaceae species, which are the main ecosystem engineers along the Garonne (Corenblit et al, ) and the Allier (Hortobágyi, Corenblit, Steiger, & Peiry, ) rivers, and show a high variability of traits and physiognomy between their growth forms (Corenblit et al, ; Kerkhoff, Fagan, Elser, & Enquist, ). Furthermore, we aggregated individual traits at the community scale, as recommended by Ackerly and Cornwell ().…”

Plant communities and dynamics can be characterized according to species composition or plant traits. Here, we used species composition and plant traits to compare their effectiveness in discriminating the biogeomorphological (involving reciprocal feedbacks between physical and biological processes) and ecological (mainly biologically driven) phases of the fluvial biogeomorphological succession (FBS) model. The comparison was done between two French rivers, the largely unchannelized lower Allier and the channelized middle Garonne. One reach representative of each river section was selected for the study. Within each river reach, we chose two contrasted study sites in terms of channel and floodplain dynamics: a reference site (least altered channel and floodplain dynamics) and an altered site (laterally stabilized by riprap and constrained). In the four study sites, we sampled vegetation in 402 plots of 4 m2. The 512 species identified in the plots were characterized in terms of plant traits (20) from a literature review. When comparing reaches in unconstrained ordinations and permutational multivariate analyses of variance, both species composition and plant traits led to a similar identification of the biogeomorphological and the ecological successional trajectories. Nevertheless, the trait approach was less influenced by local and regional bioclimatic, hydrogeomorphological, and anthropogenic settings and thus produced a more comprehensive and general classification of the biogeomorphological and ecological phases of the FBS model. A lower than expected contrast between the four sites was found, because neither species composition nor plant traits could entirely characterize distinct successional trajectories occurring in our reference or altered sites. Furthermore, our results contributed to a better understanding of the multiple successional trajectories that can occur in midlatitude river corridors. It also showed that relating plant traits to their effects on fluvial landform dynamics remains a core challenge in explaining succession including feedback mechanisms between hydrology, morphodynamics, and vegetation dynamics.

“…SfM is increasingly becoming more popular amongst scientists due to its affordability and the existence of easy-to-use commercial and open source software applications that allow even nonscientists to build three-dimensional models of surface features which are subjects of scientific research (Wróżyński, Pyszny, Sojka, Przybla, & Murat-Blażejewska, 2017). SfM has been used in a vast array of ecohydrological and river management applications such as for the observation of different river stages (Duró, Crosato, Kleinhans, & Uijttewaal, 2018;Niedzielski, Witek, & Spallek, 2016), analysis of feedbacks between fluvial geomorphology and riparian vegetation (Hortobágyi et al, 2017); floodplain inundation mapping (Schumann, Muhlhausen, & Andreadis, 2019) and river management and restoration (Kubota, Kawai, & Kadotani, 2017;Marteau, Vericat, Gibbins, Batalla, & Green, 2017).…”

“…Due to its spatial coverage, potential for high temporal repeat rates and ability to access previously unreachable locations, remote sensing has increasingly been utilized to map and monitor river environments (e.g., Carbonneau, Fonstad, Marcus, & Dugdale, 2012;Marcus & Fonstad, 2010). Furthermore, novel remotely sensed techniques involving digital photogrammetry processing techniques such as structure from motion (SfM) combined with the use of unmanned aerial vehicles (UAVs) have opened up new opportunities for costeffective, user-friendly remote sensing with high monitoring frequency and mapping of land surfaces changes on fine spatial scales (DeBell, Anderson, Brazier, King, & Jones, 2016;Hortobágyi, Corenblit, Steiger, & Piery, 2017).…”

Mediterranean intermittent rivers and ephemeral streams: Challenges in monitoring complexity

et al. 2019

In most cases, intermittent rivers and ephemeral streams (IRES) form the principal surface water bodies in Mediterranean regions and people are heavily dependent on them. Strong reliance on such streams results in numerous pressures, and complex relationships are formed between their various natural and anthropogenic components, which creates numerous challenges to decision-makers who require a better understanding of IRES to establish effective measures to restore ecosystem functionality and implement changes, while maintaining human well-being. In this paper, we present a conceptual framework that identifies process cascades and links to identify the variables governing Mediterranean IRES and map their complex interrelations.Climate is the main external driver, and it affects IRES through precipitation, temperature, wind action, and geomorphic factors, which in turn influence the physical and biological attributes of IRES. Monitoring challenges and knowledge gaps are presented from the conceptual framework, highlighting the need to identify solutions for the monitoring and mapping the spatio-temporal variability of flow regimes and their influence on bio-physical variables and mapping and quantifying ecosystem services for integrated environmental management. Finally, we argue that remote sensing techniques, specifically, the combined use of unmanned aerial vehicles and structure from motion photogrammetry, are key to bridging gaps in understanding and meeting the challenges of managing Mediterranean IRES.

“…An increasing body of studies explicitly focuses on feedbacks between plants and geomorphology to better understand structure and functions of different categories of BEs (Stallins, 2005;Corenblit et al, 2009;Eichel et al, 2013). Analyses of data collected in situ are commonly conducted with exploratory multivariate tools using pairs of environmental and plant species data tables (Gurnell et al, 2010;Eichel et al, 2015;Hortobágyi et al, 2018). To explore a link between geomorphic and biological variables, canonical correspondence analysis (CCA, Ter Braak, 1986), canonical correlation analysis (CANCOR, Hotelling, 1936), redundancy analysis (RDA, Rao, 1964), co-inertia analysis (COIA, Dolédec and Chessel, 1994), and non-metric multidimensional scaling (NMDS, Kruskal and Wish, 1978) are widely used.…”

A bivariate model for estimating reciprocal causality within biogeomorphic ecosystems: The cross‐lagged panel model

Biogeomorphic ecosystems (e.g. rivers, salt marshes, mangroves and coastal dunes) are shaped by feedbacks between geomorphology and engineer plants that occur at various spatiotemporal scales. The classical bivariate and multivariate statistical methods currently used in biogeomorphology do not permit clear identification of reciprocal causality between geomorphic and biological variables. The aim of this article is to present the potential of the cross‐lagged panel model (CLPM) to estimate reciprocal associations (causality) between one geomorphic and one biological variable over time. This tool, which originates from behavioural, social, medical and educational sciences, has clear potential as a novel approach to causal analysis in the context of biogeomorphic ecosystems. We provide a case study of the application of CLPM for analysing biogeomorphic feedbacks between topography and Populus nigra L. physiognomy on a wooded point bar of the Garonne River, France. © 2018 John Wiley & Sons, Ltd.
