Evaluation of Tikrit Dune Sand Soil Enhanced with CKD

E3S Web of Conferences, 2023
Dune sands occupy large parts of Iraq, posing significant challenges for infrastructure building. Geotechnical research and stabilization for dune soils are necessary to determine the engineering features of these soils as a foundation material in ...

Effects of organic amendments on sand dune fixation

International Journal of Recycling of Organic Waste in Agriculture
Background Poor physical and chemical properties of sand dune soil are the main constrains in afforestation of sand dune in desertified area. The aim of this study is to improve the physical and chemical properties of dune soil in Elrawakeeb Dry Land ...

Spatial Variation in Coastal Dune Evolution in a High Tidal Range Environment

Remote Sensing, 2020
Coastal dunes have global importance as ecological habitats, recreational areas, and vital natural coastal protection. Dunes evolve due to variations in the supply and removal of sediment via both wind and waves, and on stabilization through vegetation ...

Effects of spacing and admixture of three leguminous species on above ground biomass on sandy hills of Khuzestan, Iran [PDF]

تحقیقات جنگل و صنوبر ایران, 2011
In order to study the above ground biomass of three leguminous species in different planting (pure and mixed) for biological sand dune fixation, this investigation was carried out on sandy hills of Khuzestan province, located in southwest of Iran.

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

Journal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

Oikos, EarlyView.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

The Bet-Hedging Strategies for Seedling Emergence of Calligonum mongolicum to Adapt to the Extreme Desert Environments in Northwestern China

Frontiers in Plant Science, 2018
Calligonum mongolicum is a dominant native perennial shrub on sand dunes in arid deserts of northwestern China, and is therefore widely used in sand dune stabilization in these regions.

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.
