The rapid decline in the extent and health of coastal salt marshes has created a need for nondestructive methods for evaluating the condition of salt marsh ecosystems. This paper describes simultaneous uses of field sampling and remote sensing approaches to understand salt marsh ecosystem functions and species distributions and discusses the implications for salt marsh monitoring using remote s...

Plants species require macro and micro nutrients to complete the growth cycles such as photosynthesis, enzyme activities and secondary metabolite production. The objective of the present study was to investigate the effects of salinity on biomass as well as macro and micro nutrients uptake in the medicinal plant of Andrographis paniculata (AP). In this regard, a split plot experiment was carrie...

low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...

this research was carried on in order to investigate the response of wheat cultivars to salinity tension as factorial experiment and in complete randomized block design in four replications in islamic azad university shoushtar branch. in this experiment the response of nine wheat cultivars including chamran, karchia66, mahoti, roshan, alvand, kavir, ghods, atrak and tjan at vegetative growth st...

abstract- the crop water stress index (cwsi) is the most common index to monitor and assess crop water stress, based on canopy temperature. to calculate cwsi, upper and lower baselines adaptable to different environments are needed. in this study, empirical and theoretical limiting baseline equations were developed to determine eggplant cwsi values at different levels of water deficit and salin...

Transparency is an effective form of camouflage, but it must be present throughout the entire volume of an animal to succeed. Certain environmental stressors may cause physiological responses that increase internal light scattering, making tissue less transparent and more conspicuous to predators. We tested this in the transparent grass shrimp, Palaemonetes pugio, which is found in shallow estu...
