Nearly 40-50% of total global photosynthesis occurring on earth is primarily due to the presence of these algal populations [1]. Microalgae have been identified as a viable feedstock for biofuels due to their efficient capabilities to convert sunlight and CO2 to biomass (which is of great importance for the feed, fuel and chemical industries), can thrive in fresh to saline waters, and the abili...

Construction of coastal ports makes port area and nearby sea area become high risk region of ecological emergency and environmental pollution. It is helpful for providing references to protect ecological environment of port by quantifying port ecological carrying capacity. This paper will transfer resources and energy consumed in port production and operation to four ecological productive lands...

Introduction Soil salinity is an important limiting factor for crop yield improvement, which affects 5-10% of arable lands approximately 75-100 million ha worldwide, depending on estimates (Szabolcs, 1994; Munns, 2002). Most crops are sensitive to salt stress at all stages of plant development, from seed germination through vegetative and reproductive growth. Salt originates from marine geologi...

biodiversity refers to all forms of living animals, plants and microorganisms and agro-biodiversity is a component of biodiversity that represents diversity in arable lands. the aim of this study was to determine the biodiversity status of agro-ecosystems of shahr-e-rey city located in south of tehran, through calculating species richness index using rarefaction method. to the collect required ...

Data on the dynamics of species composition resource plants postagrogenic and forest lands are presented. The object study is abandoned arable land fields, felling with growth pine crops. Over period from 2006 to 2021, projective cover vegetation have changed. Judging by value coefficient floristic generality P. Ja??ard, in coincided only 27%, 15 years later - 36%. Thus, as environment formed a...
