Abstract Riparian vegetation responds to hydrogeomorphic disturbances and environmental changes also controls these changes. Here, we propose that the control of sediment erosion deposition by riparian is a key geomorphological ecological (i.e. biogeomorphic) function within fluvial corridors. In 3 year study, investigated correlations between dynamics along transverse gradient from main channel floodplain River Tech, France. Sediment rates varied significantly as biovolume intercepting...
Abstract Aim Within fluvial and coastal ecosystems world‐wide, flows of water, wind sediment generate a shifting landscape mosaic composed bare substrate pioneer mature vegetation successional stages. Pioneer plant species that colonize these at the land–water interface have developed specific traits in response to environmental constraints (response traits) are able modify habitat conditions by modulating geomorphic processes (effect traits). Changes environment under control engineer...
ABSTRACT Aim To contribute to the development of a macroevolutionary framework for riparian systems, reinforcing conceptual linkages between earth surface processes and biological ecological processes. Location Riparian systems. Methods Literature review leading an original proposition perceiving functioning systems in new different way. Results provide diverse landforms, habitats resources animals plants. Certain organisms, defined as ‘ecosystem engineers’, significantly create modify...
ABSTRACT Riverine ecosystems are recurrently rejuvenated during destructive flood events and vegetation succession starts again. Poplars (i.e. species from Populus genera) respond to hydrogeomorphological constraints, but, in turn, also influence these processes. Thus, poplar development on bare mineral substrates is not exclusively a one‐way vegetative process. Reciprocal interactions adjustments between sediment dynamics their life cycle lead the emergence of biogeomorphological entities...
Abstract River ecological functioning can be conceptualized according to a four‐dimensional framework, based on the responses of aquatic and riparian communities hydrogeomorphic constraints along longitudinal, transverse, vertical temporal dimensions rivers. Contemporary vegetation responds river dynamics at timescales, but vegetation, in one form or another, has existed Earth since least Middle Ordovician ( c . 450 Ma) been significant controlling factor geomorphology Late Silurian 420 Ma)....
Abstract Earth surface processes and landforms may have coadjusted † with plant morphology, biomechanics life‐history. We suggest that the colonization of land by plants at early Silurian, their propagation inside continents, represent critical phases coupling between geomorphic biological on a global scale. The consideration this involving geomorphic‐biological feedback mechanisms scales ecological succession organisms' evolution promote emergence an evolutionary geomorphology. Copyright ©...
Abstract This study compares the total suspended sediment (TSS), dissolved solids (TDS), and organic carbon (DOC) dynamics of two major inter‐tropical rivers, Congo in Central Africa Orinoco South America, focusing on sampling undertaken during period 2006–2010. Both rivers are characterized by similar mean annual discharges into Atlantic Ocean, its eastern western margins, respectively. For both results presented placed context available longer‐term hydrological time series (Congo:...
Abstract Populations of the riparian pioneer species Populus nigra L. which establish on alluvial bars within river channels modulate sediment dynamics and fluvial landforms. Dense cohorts P. have colonized gravel point along channelized River Garonne, France, during last 20 years enhanced vertical, lateral longitudinal development bars. For this period, geomorphic characteristics two wooded laterally stable are closely linked to spatial distribution intensity establishment resistance...
Abstract Plant communities and dynamics can be characterized according to species composition or plant traits. Here, we used traits compare their effectiveness in discriminating the biogeomorphological (involving reciprocal feedbacks between physical biological processes) ecological (mainly biologically driven) phases of fluvial succession (FBS) model. The comparison was done two French rivers, largely unchannelized lower Allier channelized middle Garonne. One reach representative each river...
Abstract Feedback between hydrogeomorphological processes and riparian plants drives landscape dynamics vegetation succession in river corridors. We describe the consequences of biogeomorphological feedback on formation vegetated fluvial landforms based observations from channelized Isère River France. The channel was laterally confined with embankments mostly straightened. From beginning 1970s to end 1990s, alternate bars were progressively but heavily colonized by vegetation. This context...
Rivers have an intricate relationship with the vegetation that colonizes them. Riparian plants, capable of thriving within river corridors, both respond to and influence geomorphology. Yet interactions between morphodynamics tend be context specific, making it challenging generalize findings locations. The current comprehension interaction physical processes, especially its effects on morphodynamics, still lacks clarity. This article examines numerous sources variation in plant responses to,...
Detecting signatures of life in sedimentary rocks lies the difficulty distinguishing them from abiotic signals and interpreting their formational conditions, particularly when working on planetary systems that are different Earth, such as Mars (Corenblit et al., 2023). Research this field is booming, thanks to development deployment detection tools either orbit or surface. great interest due its early history comparable Earth during Noachian period > 3.7 Ga (Lapôtre, 2022).

Abstract Fluvial processes of erosion, sediment transport and deposition determine the changing form sedimentary structure naturally adjusting riparian zones. Riparian storage has both scientific management importance in relation to: (i) quantities that are involved; (ii) quality sediment; (iii) dispersal biological materials, notably vegetation propagules transported deposited association with sediment. After discussing significance sedimentation processes, this paper reviews methods for...
This paper focuses on one aspect of riparian zone change associated with channel incision. It presents information sedimentation within the River Garonne, France, derived from both historical and contemporary sources. The investigated is morphologically complex, containing a remnant island cut-off channel. Information drawn sources permits reconstruction planform cross-profile change, as well an assessment changes in rates patterns. Very significant are identified over last 50 years:...

Abstract Climate change and river regulation are negatively impacting riparian vegetation. To evaluate these impacts, process‐based models preferred over data‐driven approaches. However, they require extensive knowledge about ecohydrological processes. facilitate the implementation of such models, key drivers woodland successional pathways across three reaches, in Austria, Portugal, Spain, were explored, employing two complementary The principal component analyses highlighted importance...

Many riparian ecosystems in European temperate regions have lost their inherent, highly dynamic character due to human-induced impacts such as river channelization and flow regulation. The lower course of the Allier River (France) is one last remaining free meandering segments, thus, constitutes an opportunity investigate succession processes a dynamic, system. We analyzed (i) dynamics phases based on eight sets aerial images corridor over five decades (1967-2014), (ii) dominant trajectories...
