Simaroubaceae is a monophyletic family in the order Sapindales with 22 genera and 109 species. Ailanthus altissima (Mill) Swingle, also known as the tree of heaven, is a highly invasive species, which systematically belongs to Simaroubaceae. Reproductive characteristics are essential for the deployment and maintenance of invasive species in new environments and examination of the reproductive s...
more than 32 alien (exotic) fish species belonging to 10 orders and 12 families (cyprinidae, gobiidae, salmonidae, anguilidae, mugilidae, centrarchidae, heteropneustidae, gasterosteidae, cichlidae, poecilidae, adrianichthyidae and pleuronectidae) were reported from iran of which 25 species are confirmed by specimens. some of the alien fishes (e.g., cyprinus carpio , carassius auratus , pesudora...
Shipping is among the most important ways to transfer the non-native species. In the present study, the transferability of the plankton species by the ballast water of 10 ships entering the Bushehr Port in the Persian Gulf has been investigated. The values of physicochemical parameters measured in the ballast waters showed that the average temperature, pH, salinity and TOC, were 26.2 0C, 8.17, ...
The risk of dispersing invasive species, especially human pathogens, through acts of bioterrorism, cannot be neglected. However, that risk appears quite low in comparison with the risk of dispersing animal pathogens that could dramatically burden the agricultural economy of food animal producing countries, such as Australia and countries in Europe and North and South America. Although it is not...
The present study aims to predict the potential geographic distribution and future expansion of invasive alien lionfish (Pterois miles) with ecological niche modelling along the Mediterranean Sea. The primary data consisted of occurrence points of P. miles in the Mediterranean and marine climatic data layers were collected from global databases. All the used models run 100% su...
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...
Invasive species are a growing threat in the United States, causing losses in biodiversity, changes in ecosystems, and impacts on economic enterprises such as agriculture, fisheries, and international trade. The costs of preventing and controlling invasive species are not well understood or documented, but estimates indicate that the costs are quite high. The costs of aquatic invasive species a...
