Ecological and evolutionary processes have shaped current biodiversity patterns. For brackish-water ecosystems, Remane’s Artenminimum (‘species minimum’) concept argues that taxonomic diversity in organisms is lowest within the horohalinicum, which occurs at salinity 5 to 8. This concept developed from macrozoobenthos data; it originated from, and is still applied to, the geologically young Bal...

abstract: this study provides a new and updated checklist of the freshwater fishes of the persis region which drains to the persian gulf. the list is based on historical literature records and taxon occurrence data obtained from natural history collections and new fish collections. the confirmed freshwater fishes of the persis region (sub-basin) comprise 44 species in 34 genera, 14 families, 11...

Mozambique tilapia Oreochromis mossambicus were recently discovered in ‘Aimakapā Fishpond, a 12-hectare brackish-water wetland complex in Kaloko-Honokōhau National Historical Park, on the Island of Hawai’i. As a possible eradication method, we evaluated rotenone, a natural piscicide used in fish management and the active ingredient in plants traditionally used by indigenous Hawaiians for captur...

BACKGROUND Praziquantel (PZQ) is an effective pesticide against monogeneans. Its pharmacokinetics in fish may be affected by water environment and temperature. The present study was designed to compare the pharmacokinetics, tissue distribution, and elimination of PZQ in freshwater-acclimated grass carp and brackish water cultured grass carp. Plasma and tissue PZQ concentrations were determined ...

The diamondback terrapin, Malaclemys centrata centrata (Latreille), is a thoroughly aquatic turtle living in salt and brackish marshes and estuaries. From its habitat, it is obvious that this animal has to contend with various osmotic conditions. Bentley, Bretz & Schmidt-Nielsen (1967) and just recently Dunson (1969) have already investigated the problem of the salt and water balance in that sp...

Wetland grasses and grass-like monocots are very important natural remediators of pollutants. Their genetic improvement is an important task because introduction of key transgenes can dramatically improve their remediation potential. Tissue culture is prerequisite for genetic manipulation, and methods are reported here for in vitro culture and micropropagation of a number of wetland plants of v...

Abstract. Since the Quaternary Period, paleo-seawater intrusions have been suggested to explain observed saline groundwater that extends far inland in coastal zones. The Luanhe River delta (northwest coast of Bohai Sea, China) is characterized by distribution saline, brine, brackish, and fresh from coastline inland. this region exhibits a wide range total dissolved solids (TDS): 0.38–125.9 g L−...
