Kol River drains into the Persian Gulf and its watershed encompasses areas in Hormozgan, Kerman and Fars provinces. Identification of fish species of the river was conducted seasonally from summer to winter 2005. We selected 8 sampling stations based on the height of sea level from branches of Kol River near estuary. Totally, 160 specimens were caught with gillnet, cast net and hook. We i...
The genus Aphanius belong to the family Aphaniidae which is widely distributed in the Mediterranean basin, the Red Sea, the Persian Gulf and brackish and freshwaters of Iran, Pakistan and India. To date, 14 species have been described under the genus Aphanius, in Iran.

Disease-mediated threats posed by exotic species to native counterparts are not limited to introduced parasites alone, since exotic hosts frequently acquire native parasites with possible consequences for infection patterns in native hosts. Several biological and geographical factors are thought to explain both the richness of parasites in native hosts, and the invasion success of free-living e...
Both ecological and evolutionary processes can influence community assembly and stability, and native community members may respond both ecologically and evolutionarily as additional species enter established communities. Biological invasions provide a unique opportunity to examine these responses of native community members to novel species additions. Here, I use reciprocal transplant experime...
Exotic species have become increasingly significant management problems in parks and reserves and frequently complicate restoration projects. At the same time there may be circumstances in which their removal may have unforeseen negative consequences or their use in restoration is desirable. We review the types of effects exotic species may have that are important during restoration and suggest...
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...
Widespread replacement of native ecosystems by productive land sometimes results in the outbreak of a native species. In New Zealand, the introduction of exotic pastoral plants has resulted in diet alteration of the native coleopteran species, Costelytra zealandica (White) (Scarabaeidae) such that this insect has reached the status of pest. In contrast, C. brunneum (Broun), a congeneric species...
EWE, S.M.L., and STERNBERG, L.S.L., 2006. Water uptake patterns of an invasive exotic plant in coastal saline habitats. Journal of Coastal Research, 22(0), 000–000. West Palm Beach (Florida), ISSN 0749-0208. Schinus terebinthifolius Raddi (Schinus) is one of the most widely found woody exotic species in South Florida. This exotic is distributed across environments with different hydrologic regi...
