A total of 33 taxa of scaled chrysophytes were observed from 50 localities in and around the delta region of the Parana River, situated in the subtropics of Argentina. The study sites were divided into five groups based on their physical and chemical characteristics and location within the delta complex. The five groups included waterbodies situated on the delta, channels of the river, tributar...

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...

OBJECTIVE To investigate the possibility of Aphanius dispar (A.dispar) acting as intermediate host for Clinostomum complanatum (C. complanatum), from Mehran River, Hormuzgan Province of Iran. METHODS During a biological study of A. dispar in Mehran River, Hormuzgan Province, South of Iran, a total of 97 fish specimens were collected in 24 January 2006. RESULTS 4 specimens (4.12%) including ...

the reproductive biology of the iranian cichlid, iranocichla hormuzensis coad, 1988, was investigated for 13 consecutive months in lower mehran river, from august 2008 through august 2009. four hundred and eighty six individuals (252 males and 234 females) were captured using a seine net (5 mm mesh size). the observed sex ratio was 1m: 0.93f (χ², df = 1, p = 0.414). mean ± sd of total length (t...

Wetlands and water bodies in the Parana Delta River and Ibera System of northeast Argentina were studied for scaled chrysophytes. The Delta region of the Parana River is composed of a series of braided channels, streams and lagoons that extend over 17,500km2. Although the Delta is situated in the temperate zone, it experiences a more subtropical climate. The water ways of the Ibera System consi...

Megalopolis is a group of densely populated metropolitan areas that combine to form an urban complex. Since China introduced the economic reforms in late 1970s, the Chinese urban system has experienced unprecedented growth. The process of urbanisation prevailed in the 1980s, and the process of predominantly large city growth appeared to continue through 1990s and 2000s. In this study, the magni...
