Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, EarlyView.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Propagation and Production of Seacoast Marshelder

EDIS, 2004
Seacoast marshelder (Iva imbricata Walter [Asteraceae]), occurs on coastal dunes throughout the south Atlantic and Gulf region (coastal Virginia to coastal Texas) and is used for dune restoration and stabilization projects (Figure 1).

Seagrasses are most vulnerable to marine heatwaves in tropical zones: local‐scale and broad climatic zone variation in thermal tolerances

New Phytologist, EarlyView.
Summary Under a changing climate, it is imperative that we understand how species may respond to temperature impacts, which can differ among populations of the same species due to local drivers. Thermal tolerance data, which can be used to assess an organism's upper thermal limits, is valuable to identify species and/or populations' susceptibility to ...

Valorisation of Dune Sand Treated with Lime and Scrap Tyre Rubber Powder as a Road Foundation Material.

Journal of Materials and Engineering Structures, 2020
The purpose of the work presented in this paper is the treatment of dune sand; which is abundant in the region of  Djelfa (Algeria), with different lime and tyre rubber powder in order to valorise them in road construction.

Divergent Phosphorus‐Mining Strategies in Simple and Compound Cluster Roots in Extremely Phosphorus‐Impoverished Soils in Southwest Australia

Plant, Cell &Environment, EarlyView.
ABSTRACT Most Proteaceae and some Fabaceae species produce specialised cluster roots (CRs), and are abundant in severely phosphorus (P)‐impoverished soils in southwest Australia. Two types of CRs, compound and simple, have been identified. However, the difference in their P‐mining strategies remains unclear. Therefore, we conducted glasshouse and field

Evaluating the Effect of Cement and ARG Fiber on the Mechanical and Microstructural Properties of Dune Sand

Advances in Civil Engineering
Despite its collapsible nature and weakness, desert sand can be used for construction purposes all over the world if properly stabilized. Therefore, the aim of this study is to evaluate the effectiveness of cement and fiber in stabilizing locally ...

Wetland plant growth in recycled glass sand versus dredged river sand: evaluating a new resource for coastal restoration

Restoration Ecology, EarlyView.
Sand made from recycled glass cullet could supplement limited dredged river sand (dredge) in coastal wetland restorations; however, its suitability for wetland plants is unknown. In two experiments, we compared the biomass of several wetland plants in recycled glass sand to growth in dredge.

Field‐grown coastal dune plants exhibit similar survival, growth, and biomass in recycled glass substrate and natural beach sand

Restoration Ecology, EarlyView.
Restoration of coastal dunes following tropical storm events often requires renourishment of sand substrate dredged from offshore sources, although dredging has well‐described negative ecological impacts and high economic costs. As a potential solution, recycled glass sand (cullet) made from crushed glass bottles has been proposed as a potential ...
