This paper is in line with the previous publication on the wood inhabiting Hyphomycetes from Gilan province (Iran). As a results, 22 taxa were identified which are listed as follows: Arthrinium state of Apiospora montagnei, Arthrinium saccharicola, Arthrobotrys sp., Berkleasmium sp., Clonostachys rosea, Cryptocoryneum sp., Cylindrocladium colhonii, Dendrostilbella sp., Dendryphion comosum, Endo...

every year a large number of migratory wintering water birds, rest in the wetlands situated in the northern provinces of iran. the wetlands are very important ecosystems for these creatures. due to ecological importance of water birds, the results of this study (the birds’ populations and their changes) are helpful to monitor them and are especially important to manage the wetlands. in this stu...

gilan province is among the most important regions of iran for rice production. the general aim of this research is to determine the best variety of rice for planting, so that the minimum level for farmer's expected living gross margin can be provided. on the other hand, determining the best variety with regard to the risk in price is another aim of this research. to this end two risk models ba...

Over the past few years, the syndrome of streptococcosis has been associated with outbreaks in rainbow trout (Oncorhynchus mykiss, Walbaum) and caused significant economic losses in the aquaculture industry in Iran. The main purpose of this work was molecular identification of some causative agents of streptococcosis in rainbow trout.

Abstract Estimating sediment load of rivers is one the major problems in river engineering that has been using various data mining algorithms and variables. It desirable to obtain accurate estimates while techniques limit computational intensity when datasets are large. This study investigates usefulness geo-morphometric factors machine learning (ML) models for predicting suspended (SSL) severa...

nowadays, invasive species are a major threat to biodiversity and create many economic losses. modeling for predict the distribution trends of invasive species is considered as a biodiversity management tool. raccoon is a native species in north and central america, and nowadays it is an invasive species in many countries such as japan, germany and russia. raccoon was observed for the first tim...
