Beaver have expanded in their native habitats throughout the northern hemisphere in recent decades following reductions in trapping and reintroduction efforts. Beaver have the potential to strongly influence salmon populations in the side channels of large alluvial rivers by building dams that create pond complexes. Pond habitat may improve salmon productivity or the presence of dams may reduce...
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...

We documented riparian primary succession on an expansive floodplain (Kol River, Kamchatka, Russian Federation) that receives large nitrogen subsidies from spawning Pacific salmon. As is typical of primary succession, new alluvial deposits in the lower Kol floodplain were nitrogen poor (200 kg persulfate N/ha to 10 cm soil depth); however, nitrogen accumulated rapidly, and soils contained 1600 ...
The Iranian Persian chub is an endemic species of the family Cyprinidae known only from few localities in drainages of Southern Iran. It was originally described in the genus Pseudophoxinus as (Pseudophoxinus persidis) and then Petroleuciscus (as Petroleuciscus persidis). In this study, we examined phylogenetic relationships of the Iranian Persian chub with other relatives in the family Cyprini...
Iranocichla persasp. n. is described from the Shur, Hasanlangi and Minab River drainages flowing into the Persian Gulf at the Strait of Hormuz in southern Iran. It is distinguished from Iranocichla hormuzensis, from the Mehran River drainage, by nuptial males having a bright orange breast and lower part of the head (vs. black), a poorly developed or invisible (vs. distinctive) "Tilapia-mark" in...

Kol and Homburg recently hypothesized in these pages that the change, rather than currently evaluated absolute hormone values, is important for biological processes. We fully agree, but wish, with this communication, to add to their concept: opposing forces, balancing each other, in order to maintain a system's stability, permeates nature. Loss of such equilibrium, in turn, results in systemic ...
Barbatula restricta, new species, is described from the Saldan-Kol Lake in the upper Ob River drainage in the Altai Mountains. It is distinguished from all other species of Barbatula in Asia by its body depth increasing continuously between the nape and the dorsal-fin origin and a combination of characters: nares widely spaced, upper lip with a short medial incision, lower lip without lateral e...
