“…The role of engineer species in modifying sediment dynamics and landform processes has recently caught the interest of the scientific community with respect to biogeomorphology e.g. 1,2 . Currently, biogeomorphology research is focused on water sediment-driven systems in coastal areas where plant species play a key role in shaping the ecosystem e.g.…”

Striped seagrass meadows are formed by narrow ribbons which are elevated over the seabed and separated by channels. Limited information on the genesis and development of this morphological pattern, including the adaptive responses of associated biota, is preventing holistic insight into the functioning of such protected ecosystems. This paper assessed the structural dynamics of a Posidonia oceanica striped meadow and the distribution and 3D orientation of the associated bivalve Pinna nobilis . Our analysis of the interaction between bedforms, bottom currents, and the distribution of P. nobilis revealed that the striped seascape is the result of a self-organisation process driven by feedback interactions among seagrass growth, sediment deposition, and hydrodynamics. The results suggest that the ribbon wall is the most suitable sub-habitat for this species, because it supports the highest density of P. nobilis, compared to the meadow top and bottom. Here, specimens can take advantage of the resuspension induced by hydrodynamics and open their shells towards the current, thus enhancing food intake. Therefore, our results show that self-organisation in striped seagrass meadow affects the distributional pattern of P. nobilis, providing new insights into the autoecology of this species beyond the conservation implications for its habitat.

In agreement with the coastal sedimentary environment, a distinction between different scales and associated fluvial landforms can be made, although cross‐scalar linkages are increasingly a focus area (Gurnell et al ., 2019; Kleinhans et al ., 2019; Rice et al ., 2019).…”

“…At the small scale, research has focused on the relationships between bioweathering, bioerosion, and bioprotection (e.g. Naylor et al ., 2012; Coombes et al ., 2013; Coombes, 2016). At a larger scale, several efforts are aimed at investigating the effects of animal burrowing on sediment transport (e.g.…”

Biogeomorphology has been expanding as a discipline, due to increased recognition of the role that biology can play in geomorphic processes, as well as due to our increasing capacity to measure and quantify feedback between biological and geomorphological systems. Here, we provide an overview of the growth and status of biogeomorphology. This overview also provides the context for introducing this special issue on biogeomorphology, and specifically examines the thematic domains of biogeomorphological research, methods used, open questions and conundrums, problems encountered, future research directions, and practical applications in management and policy (e.g. nature‐based solutions). We find that whilst biogeomorphological studies have a long history, there remain many new and surprising biogeomorphic processes and feedbacks that are only now being identified and quantified. Based on the current state of knowledge, we suggest that linking ecological and geomorphic processes across different spatio‐temporal scales emerges as the main research challenge in biogeomorphology, as well as the translation of biogeomorphic knowledge into management approaches to environmental systems. We recommend that future biogeomorphic studies should help to contextualize environmental feedbacks by including the spatio‐temporal scales relevant to the organism(s) under investigation, using knowledge of their ecology and size (or metabolic rate). Furthermore, in order to sufficiently understand the ‘engineering’ capacity of organisms, we recommend studying at least the time period bounded by two disturbance events, and recommend to also investigate the geomorphic work done during disturbance events, in order to put estimates of engineering capacity of biota into a wider perspective. Finally, the future seems bright, as increasingly inter‐disciplinary and longer‐term monitoring are coming to fruition, and we can expect important advances in process understanding across scales and better‐informed modelling efforts. © 2020 The Authors.

“…This has given impetus to the emerging discipline of eco‐hydromorphology (Clarke, Brucea‐Burgess, & Wharton, ; Vaughan et al, ), evidenced by new legislative drivers (EC Habitats Directive, Water Framework Directive, WFD; Vaughan & Ormerod, ), and increased research combining ecology, hydrology, and fluvial geomorphology as a response to concerns about anthropogenic impacts (e.g., riparian loss, abstraction, damming, and channelization) on river systems. Eco‐hydromorphology with its origins (Hickin, ; Thorne, ; Coombes, ) in bio‐geomorphology is now a highly active research area at the interface between ecology and geomorphology, focusing on the many and varied interactions and feedbacks between organisms and the physical Earth. However, perhaps due to its infancy as a discipline, research reporting on the eco‐hydromorphological consequences of climate change for river systems has, thus far, been limited (Baptist, ; Martínez‐Fernández, Van Oorschot, De Smit, González del Tánago, & Buijse, ), including where ecosystem instability is likely to occur at the regional, catchment or habitat scale.…”

Climate change and European rivers: An eco‐hydromorphological perspective

Climate change is expected to modify temperature and precipitation patterns throughout Europe, leading to warmer drier summers; wetter, milder winters; and an extended growing season. Alterations to feedbacks between important eco‐physical structuring processes driven by climate change may modulate river morphology, floodplain characteristics, and their biological communities. Current understanding is reviewed and synthesised to explore the potential responses, mechanisms, and ramifications of climatic shifts for the European riverscape. Fundamental drivers of change are expected to be (a) disturbance deviation beyond the historical norm and (b) vegetation morphodynamics, a key river process where ecological and fluvial‐geomorphological attributes interact to shape the physical environment. Increased seasonal temperature, summer drought, and winter flooding may affect the colonisation, growth, and mortality of plant species with consequences for riverscape structure and function as succession patterns adjust with repercussions for hydraulics and sediment dynamics. Such opposing winter and summer climate regimes are likely to impact vegetation patch dynamics, reflected in an increasingly variable patch mosaic as disturbance intensity deviates further from historical background conditions. How changes to climate drivers manifest themselves in individual river systems will also be affected by attributes such as catchment topography, geology, vegetation type, and previous human alterations. Where large scale change occurs, it will have consequences for the type and function of biological communities inhabiting the riverscape. Conventional engineering responses to meteorological disturbance will amplify the effect on river biota by reducing their ecological resilience, highlighting the need for a management response that integrates ecological and societal benefits simultaneously.
