“…However, this could result from autocompaction, as indicated above, in the estuarine sediments or reflect tidal changes within the estuarine system70. While regionally, data from Quarteira, does not support that claim, this inflexion has been reported in several estuaries707172 demanding further research.…”

The uncertainties surrounding present and future sea-level rise have revived the debate around sea-level changes through the deglaciation and mid- to late Holocene, from which arises a need for high-quality reconstructions of regional sea level. Here, we explore the stratigraphy of a sandy barrier to identify the best sea-level indicators and provide a new sea-level reconstruction for the central Portuguese coast over the past 6.5 ka. The selected indicators represent morphological features extracted from coastal barrier stratigraphy, beach berm and dune-beach contact. These features were mapped from high-resolution ground penetrating radar images of the subsurface and transformed into sea-level indicators through comparison with modern analogs and a chronology based on optically stimulated luminescence ages. Our reconstructions document a continuous but slow sea-level rise after 6.5 ka with an accumulated change in elevation of about 2 m. In the context of SW Europe, our results show good agreement with previous studies, including the Tagus isostatic model, with minor discrepancies that demand further improvement of regional models. This work reinforces the potential of barrier indicators to accurately reconstruct high-resolution mid- to late Holocene sea-level changes through simple approaches.

“…At times, historically and during the Saxby Gale in 1869 [66,67], the Isthmus has been inundated with waters from the Bay of Fundy [37,68]. Storm surges funnel up the Bay of Fundy-a dynamic marine system with the highest recorded tides in the world (16.3 m)-culminating in the Chignecto Bay [69][70][71]. The elevation of the entire region is less than 90 m above sea level and is dominated in the southern region by low-lying salt marshes, wetlands, and bogs [46].…”

Inclusive knowledge systems that engage local perspectives and social and natural sciences are difficult to generate and infuse into decision-making processes but are critical for conservation planning. This paper explores local tacit knowledge application to identify wildlife locations, movement patterns and heightened opportunities and barriers for connectivity conservation planning in a critical linkage area known as the Chignecto Isthmus in the eastern Canadian provinces of Nova Scotia and New Brunswick. Thirty-four local hunters, loggers, farmers and others with strong tacit knowledge of wildlife and the land participated in individual interviews and group workshops, both of which engaged participatory mapping. Individuals’ data were digitised, analysed and compiled into thematic series of maps, which were refined through participatory, consensus-based workshops. Locations of key populations and movement patterns for several species were delineated, predominantly for terrestrial mammals and migratory birds. When comparing local tacit-knowledge-based maps with those derived from formal-natural-science models, key differences and strong overlap were apparent. Local participants provided rich explanatory and complementary data. Their engagement in the process fostered knowledge transfer within the group and increased confidence in their experiential knowledge and its value for decision making. Benefits derived from our study for conservation planning in the region include enhanced spatial data on key locations of wildlife populations and movement pathways and local insights into wildlife changes over time. Identified contributing factors primarily relate to habitat degradation and fragmentation from human activities (i.e., land use and cover changes caused by roads and forestry practices), thereby supporting the need for conservation measures. The generated knowledge is important for consideration in local planning initiatives; it addresses gaps in existing formal-science data and validates or ground truths the outputs of existing computer-based models of wildlife habitat and movement pathways within the context of the complex social-ecological systems of the place and local people. Critically, awareness of the need for conservation and the value of the participants’ shared knowledge has been enhanced, with potential influence in fostering local engagement in wildlife conservation and other planning initiatives. Consistent with other studies, engagement of local people and their tacit knowledge was found to (i) provide important insights, knowledge translation, and dissemination to complement formal, natural science, (ii) help build a more inclusive knowledge system grounded in the people and place, and (iii) lend support to conservation action for connectivity planning and human-wildlife co-existence. More broadly, our methods demonstrate an effective approach for representing differences and consensus among participants’ spatial indications of wildlife and habitat as a means of co-producing knowledge in participatory mapping for conservation planning.

“…These changes might have impacted the tidal frame, currents and sediment transport. In fact, dramatic changes in the tidal frame have been modeled for the Bay of Fundy in response to the catastrophic breakdown of a barrier system (Shaw et al 2010). Also, tidal changes have been recorded in Delaware Bay over the last 4000 years in response to the change of the basin shape during the late Holocene sea-level rise (Leorri et al 2011).…”

Paleoenvironmental Reconstruction Project, led from Cologne University. These, and many other international scientific projects in Ethiopia, owe Mohammed a debt of gratitude: he was an essential and indefatigable colleague, making use of his wide-ranging network of friends to smooth the path of fieldwork and conferences, working with Ethiopian, French, American, German and British partners with tireless energy, great good-humor, and boundless enthusiasm. Personally, I owe much to Mohammed for 18 years of fruitful collaboration and close friendship, during which we shared many memorable times-coring Rift valley lakes, surveying Lake Tana, exploring Mechara caves, and fieldwork on horseback in the mountains of southwestern Ethiopia. Without his skills and enterprise, the work would have been almost impossible, and certainly far less enjoyable. He was a marvelous raconteur, with an in
