Post-glacial Fluvial response and Landform development in the upper Muskegon River valley in North-Central Lower Michigan, U.S.A.
2020Co-Authors: Alan F Arbogast, Juleigh R Bookout, Bradley R Schrotenboer, Amy Lansdale, Ginny L Rust, Victorino A BatoAbstract:This study focuses on the upper part of the Muskegon River system in north-central Lower Michigan and is the first to reconstruct the post-glacial history of Fluvial Landform development in the core of North America's Great Lakes region. Results indicate that the upper Muskegon River valley contains four alluvial terraces and numerous paleomeanders. Radiocarbon dating of peats within these old channels provides a good chronology for stream behavior and Landform development. The T-4 terrace is a paired Pleistocene outwash/lacustrine surface that probably formed about 12,500 years ago. The T-3 terrace is a fill-strath surface that was cut between about 12,000 and perhaps 9500 years ago. The geometry of macromeanders on this surface suggests that stream discharge was ∼ 8 times greater than during the Holocene. The Pleistocene/Holocene transition is marked by a major period of downcutting that likely began as the climate warmed/dried and sediment yield diminished. This period of downcutting potentially lasted through the drier middle Holocene, creating a 6-m-high escarpment in the valley. The Muskegon River then began to aggrade when the climate became wetter. Subsequently the river again incised, creating the paired T-2 terrace, about 3400 years ago when the climate became still wetter. T-2 paleomeanders indicate that stream discharge at this time was consistent with the modern river. In the past 2500 years, the stream has constructed a poorly defined complex of T-1 terraces. These surfaces likely formed due to complex response associated with more variable climate. This study demonstrates that the upper Muskegon River has a similar post-glacial history as streams on deglacial and periglacial landscapes elsewhere in the world

niche construction within riparian corridors part i exploring biogeomorphic feedback windows of three pioneer riparian species allier river france
2017Co-Authors: Borbala Hortobagyi, Dov Jeanfrancois Corenblit, Johannes Steiger, Jeanluc PeiryAbstract:Abstract Within riparian corridors, biotic-abiotic feedback mechanisms occur between woody vegetation strongly influenced by hydrogeomorphic constraints (e.g., sediment transport and deposition, shear stress, hydrological variability), Fluvial Landforms, and morphodynamics, which in turn are modulated by the established vegetation. During field investigations in spring 2015, we studied 16 alluvial bars (e.g., point and lateral bars) within the dynamic riparian corridor of the Allier River (France) to assess the aptitude of three pioneer riparian Salicaceae species (Populus nigra L., Salix purpurea L., and Salix alba L.) to establish and act as ecosystem engineers by trapping sediment and constructing Fluvial Landforms. Our aim is to empirically identify the preferential establishment area (EA; i.e., the local areas where species become established) and the preferential biogeomorphic feedback window (BFW; i.e., where and to what extent the species and geomorphology interact) of these three species on alluvial bars within a 20-km-long river reach. Our results show that the EA and BFW of all three species vary significantly along the longitudinal profile, i.e., upstream-downstream exposure on the alluvial bars, as well as transversally, i.e., the main hydrological connectivity gradient from the river channel toward the floodplain. In the present-day context of the Allier River, P. nigra is the most abundant species, appearing to act as the main engineer species affecting Landform dynamics at the bar scale; S. purpurea is established and acts as an ecosystem engineer at locations on alluvial bars that are most exposed to hydrosedimentary flow dynamics, while S. alba is established on the bar tail close to secondary channels and affects the geomorphology in mixed patches along with P. nigra. Our study highlights the role of functional trait diversity of riparian engineer species in controlling the extent of Fluvial Landform construction along geomorphic gradients within riparian corridors exposed to frequent hydrogeomorphic disturbances.

Populus nigra L. establishment and Fluvial Landform construction: biogeomorphic dynamics within a channelized river
2016Co-Authors: Dov Jeanfrancois Corenblit, Johannes Steiger, Angela M Gurnell, Borbala Hortobagyi, Gaspard Charrier, José Darrozes, Virginia Garófano-gómez, Alexandre Garreau, Eduardo González, Frédéric JulienAbstract: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 of P. nigra have colonized gravel point bars along the channelized River Garonne, France, during the last 20 years and have enhanced the vertical, lateral and longitudinal development of the bars. For this period, the geomorphic characteristics of two wooded point bars on this laterally stable river are closely linked to the spatial distribution and intensity of establishment and resistance of different cohorts of P. nigra. Furthermore, P. nigra colonization dynamics were controlled by engineer effects of this same species. This relationship is illustrated by a significant correlation between key geomorphic and biological variables measured in situ and characterized with a set of four aerial photographs taken between 2000 and 2010. The development of wooded point bars, which are discrete biogeomorphic units, over the studied period, appear to result from a specific biogeomorphic positive feedback of matter aggregation and vegetation establishment related to sediment trapping and stabilization by pioneer engineer plants.We propose a conceptual model of biogeomorphic unit construction for channelized, lateral stable rivers.We consider the resultant biogeomorphic units as functional from an ecological point of view because P. nigra enhances at the cohort scale (i) its own inherent capacity to resist hydrogeomorphic disturbances, and (ii) its resilience capacity as a result of successful colonization, especially downstream of mature poplar stands.

plants intertwine Fluvial Landform dynamics with ecological succession and natural selection a niche construction perspective for riparian systems
2009Co-Authors: Dov Jeanfrancois Corenblit, Johannes Steiger, Angela M Gurnell, Robert J NaimanAbstract:Aim To contribute to the development of a macroevolutionary framework for riparian systems, reinforcing conceptual linkages between earth surface processes and biological and ecological processes. Location Riparian systems. Methods Literature review leading to an original proposition for perceiving the functioning of riparian systems in a new and different way. Results Riparian systems provide diverse Landforms, habitats and resources for animals and plants. Certain organisms, defined as ‘ecosystem engineers’, significantly create and modify the physical components of riparian systems. Many studies have highlighted such engineering effects by animals on riparian systems, but the identification and understanding of the effects and responses of plants within Fluvial corridors have emerged only recently. The modulation of matter, resources and energy flows by engineering plants helps establish characteristic sequences of Fluvial Landform creation and maintenance associated with synergetic ecological successions. We relate this process to the concept of niche construction, developed mainly by evolutionary biologists. Feedbacks between adaptive responses of riparian plants to flow regime and adjusting effects on biostabilization and bioconstruction are discussed in the context of niche construction at the scale of ecological succession and the evolution of organisms. Main conclusions Our conceptualization forges an integrated approach for understanding vegetated Fluvial systems from a macroevolutionary perspective, for elucidating riparian ecosystem dynamics and potentially for establishing long-term stream conservation and restoration strategies.

reciprocal interactions and adjustments between Fluvial Landforms and vegetation dynamics in river corridors a review of complementary approaches
2007Co-Authors: Dov Jeanfrancois Corenblit, Johannes Steiger, Eric Tabacchi, Angela M GurnellAbstract:Abstract Until recently, one-way relationships between flow dynamics, geomorphology and plant ecology were considered dominantly when studying the functioning of river systems, whereby Fluvial Landforms and hydrogeomorphic processes drive the evolution of riparian plant communities. However, biological communities may significantly control geomorphic processes and have strong impacts on Landform dynamics. In order to fully identify the processes linked to river dynamics (changes in time and space of Fluvial Landforms and associated plant communities), conceptual multidisciplinary progress is clearly needed. To understand the mutual interactions and feedbacks between Fluvial Landforms and vegetation community dynamics, this paper presents a detailed literature review of Fluvial geomorphology, riparian plant ecology and hydraulic engineering knowledge. The historical and recent development of ecological plant succession theory toward the integration of hydrogeomorphic disturbances is discussed as well as the integration of vegetation within geomorphology as a significant Landform control factor, incorporating both hydrogeomorphic controls on riparian vegetation dynamics and mechanical impacts of vegetation structures on flow properties and sediment dynamics. Recent progress in ecology, hydraulic engineering and Fluvial geomorphology emphasises interdependence between biological and physical forms and processes. Based on this literature review, a ‘Fluvial biogeomorphic succession’ concept is proposed to link Fluvial Landform and riparian vegetation community evolution within a bi-directional model. The succession of Fluvial Landforms and associated vegetation communities is composed of four main critical phases that represent a shift in the relative dominance of hydrogeomorphic and ecological processes as a response to biostabilisation and passive bioconstruction processes. The positive feedbacks associated with this shift lead to the development of characteristic biogeomorphic structures such as vegetated banks, islands or floodplains, which are moderated by the biogeomorphic functional roles of ‘ecosystem engineers’ that induce or reinforce the positive feedbacks. This Fluvial biogeomorphic succession concept relates the natural Darwinian selection and ecological succession theories to Fluvial geomorphology.

Relier la biogéomorphologie Fluviale à l’écologie évolutive : un focus sur les arbres riverains pionniers
2020Co-Authors: Corenblit, Dov Jean-françois, Steiger Johannes, Mazal Lucas, Till-bottraud IrèneAbstract:International audienceWithin rivers, riparian trees such as poplars or willows respond to the flood regime, but they also controlhydrogeomorphological processes and Fluvial Landform dynamics. It is now recognized that feedbacks between riparian trees and hydrogeomorphological processes occur during their life, leading to the emergence of biogeomorphological units such as vegetated islands, river banks and floodplain surfaces. Based on our empirical observations and on a synthesis of the most recent findings in geomorphology, plant ecology and evolutionary ecology, we describe the four steps of co-construction between riparian trees and Fluvial Landforms. We describe the tight bi-directional coupling between the biological and geomorphological components as a “biogeomorphological life cycle” where the biological development of the plant requires a sequence of biotically driven geomorphological changes of the river channels. We point out that riparian trees which grow in dense stands enhance their capacity to protect each other from mechanical constraints related to water flow and sediment transport, to trap fine sediment, organic matter and nutrients and thus to survive, exploit resources, and reach sexual maturity between exceptional, high magnitude floods, i.e. facilitate each other. We suggest that direct positive interactions (cooperation and altruism) between plants could enhance the ecological process of niche construction.Dans les cours d’eau, les arbres riverains tels que les peupliers ou les saules répondent au régime de crues, mais ils contrôlent également les processus hydrogéomorphologiques et la dynamique des formes Fluviales. Il est maintenant reconnu que des rétroactions entre les arbres riverains et les processus hydrogéomorphologiques se produisent au cours de leur vie. Ces rétroactions conduisent à l’émergence d’unités biogéomorphologiques telles que des îles Fluviales, des berges et des niveaux de plaine alluviale végétalisée. À partir de nos observations empiriques et d’une synthèse des découvertes les plus récentes en géomorphologie, écologie végétale et écologie évolutive, nous présentons les quatre étapes de la co-construction entre les forêts riveraines et les formes Fluviales. Nous décrivons le couplage bidirectionnel étroit entre les composantes biologiques et géomorphologiques comme un « cycle de vie biogéomorphologique » au cours duquel le développement biologique de la plante nécessite une série de changements géomorphologiques des lits fluviaux sous contrôle biotique. Nous soulignons que les arbres riverains qui se développent dans des peuplements denses se protègent les uns les autres des contraintes mécaniques liées à l’écoulement et au transport sédimentaire. Ensemble, ils piègent également plus efficacement les sédiments fins, la matière organique et les nutriments. Ainsi, ils renforcent leur capacité à survivre, à exploiter les ressources et à atteindre la maturité sexuelle entre des crues exceptionnelles de forte magnitude, ce qui correspond à une interaction de facilitation. Nous suggérons que des interactions positives directes (coopération et altruisme) entre les plantes pourraient renforcer le processus écologique de construction de niche
