1 We investigated the factors producing zonation patterns of the dominant plants in south-eastern USA salt marshes where Juncus roemerianus dominates the high marsh, and Spartina alterniflora the middle and low marsh. 2 Juncus did not occur naturally in the Spartina zone and performed poorly when transplanted there, irrespective of whether neighbours were present or removed, indicating that its...

This project utilizes microfluidic systems to study how groups of liver cells acquire emergent tissue properties. Hepatocytes (the parenchymal cells of the liver) respond to many cues in their microenvironment: neighboring cells, growth factors, extracellular matrix, dissolved oxygen, and their interactions. One tissue property of interest is the compartmentalization of gene expression in multi...

in western and southern watersheds of isfahan province, combinations of natural and human factors have caused numerous landslides related damages. one of the main strategies for restricting the damage caused by the landslide is to avoid these regions. for this purpose, it is necessary to prepare precise landslide hazard zonation map for such areas. for this purpose, by aerial photos, satellite ...

Abstract: Aim Zooplankton functional groups play an important role in lake functioning and can readily respond to environmental changes may be associated with phytoplankton changes. In warmer regions, zooplankton species have a smaller body size, which decreases their grazing capacity, attenuating top-down control throughout phytoplankton. We evaluated density biomass of relationship algal hori...

Here, we present a novel method for culturing kidneys in low volumes of medium that offers more organotypic development compared to conventional methods. Organ culture is a powerful technique for studying renal development. It recapitulates many aspects of early development very well, but the established techniques have some disadvantages: in particular, they require relatively large volumes (1...

Land preservation and restoration are important tools for managing imperiled aquatic species, but they are often applied in the absence of a transparent scheme of geographic prioritization. To help guide preservation and restoration efforts in the Conasauga River Basin in Georgia and Tennessee, we used the “Zonation” algorithm to prioritize sub-watersheds. Zonation is a prioritization system th...

Abstract. The use of mass flow simulations in volcanic hazard zonation and mapping is often limited by model complexity (i.e. uncertainty correct values parameters), a lack quantification, approaches to incorporate this into maps. When quantified, simulation errors are typically evaluated on pixel-pair basis, using the difference between simulated observed (“actual”) map-cell evaluate performan...
