Home, with what remains: A sorting-house as a form of occupancy right

North of La Rochelle, the Baie de l'Aiguillon bears witness to a structurally invasive past, partially camouflaged in its shallow waters. 400 hectares of abandoned oyster beds locally known as crassats, remnants of the shellfish industry, lie in the intert ...

Effects of temperature on tidally influenced coastal unconfined aquifers

David Andrew Barry, Li Pu, Chenming Zhang

Aquifer-ocean temperature contrasts are common worldwide. Their effects on flow and salinity distributions in unconfined coastal aquifers are, however, poorly understood. Based on laboratory experiments and numerical simulations, we examined the responses ...

Inorganic carbon and nitrogen assimilation in cellular compartments of a benthic kleptoplastic foraminifer

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin, Maria-Evangelia Giovani

Haynesina germanica, an ubiquitous benthic foraminifer in intertidal mudflats, has the remarkable ability to isolate, sequester, and use chloroplasts from microalgae. The photosynthetic functionality of these kleptoplasts has been demonstrated by measuring ...

An overview of cellular ultrastructure in benthic foraminifera: New observations of rotalid species in the context of existing literature

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

We report systematic transmission electron microscope (TEM) observations of the cellular ultrastructure of selected, small rotalid benthic foraminifera. Nine species from different environments (intertidal mudflat, fjord, and basin) were investigated: Ammo ...

Cellular pathways of carbon and nitrogen assimilation in kleptoplastic foraminiferal species

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Kleptoplasty is the process by which an organism sequesters algal chloroplasts while discarding or digesting other algal components. This ability is encountered in different organisms, including benthic foraminifera. Among kleptoplastic foraminiferal speci ...

A benthic foraminifera species respond to anoxia with a strong metabolic shift suggesting a state of dormancy

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Low-oxygenation events are more and more frequent and strong on continental shelves and in coastal areas where renewal of bottom waters is slow. Among the meiofauna living in such environments, foraminifera are among the most tolerant to the lack of oxygen ...

Unstable Pore-Water Flow in Intertidal Wetlands

David Andrew Barry

Salt marshes are important intertidal wetlands strongly influenced by interactions between surface water and groundwater. Bordered by coastal water, the marsh system undergoes cycles of inundation and exposure driven by the tide. This leads to dynamic, com ...

Tidally driven multiscale pore water flow in a creek-marsh system

David Andrew Barry

Intertidal wetlands are complex hydrological systems characterized by strong, dynamic interactions between coastal surface water and groundwater, driven particularly by tides. We simulated such interactions with a focus on three-dimensional, variably satur ...

Tide-induced surface water and groundwater interactions in coastal wetlands

David Andrew Barry

Intertidal wetlands such as salt marshes are complex hydrological systems characterized by strong, dynamic interactions between coastal surface water and groundwater, driven particularly by tides. We simulated such interactions with a focus on 3D, variably ...

Developing methods to assess the extent of naturalized slash pine populations and their habitats characteristics in South East Queensland, Australia

Blaise Etienne Marceau Dhont

Slash pine is an exotic commercial species that is widely planted across South East Queensland’s coastal region. Several studies have observed naturalized slash pine populations around plantations, although there have been minimal efforts to control report ...
