Riparian forest potential to retain sediment and bromophenol concentrations in fish.
Biodiversity conservation has attracted growing concern and importance for global stability. The data presented by Luiz F. Pires and colleagues in this issue of the Anais da Academia Brasileira de Ciências (AABC) may soon earn some praise regarding a more effective stability of biodiversity. Their study aimed to check the efficiency of a riparian forest in trapping sediments coming from an upla...
متن کاملRiparian forest potential to retain sediment and carbon evaluated by the 137Cs fallout and carbon isotopic ratio techniques.
Riparian forests can provide an important service for aquatic ecosystems by sequestering hillslopederived sediments. However, the width of a riparian buffer zone required to filter sediments is not yet wellunderstood. Here are used two complementary tracers to measure sediment retention. The 137Cs technique and the soil carbon isotopic ratios (delta13C) are utilized to investigate sediment depo...
متن کاملBromophenol concentrations in fish from Salvador, BA, Brazil.
The main objective of this work is to evaluate the occurrence of bromophenols (2bromophenol, 4bromophenol, 2,4dibromophenol, 2,6dibromophenol and 2,4,6tribromophenol), in the flesh and guts in two species of the LutjanidaeFamily: Lutjanus synagris and Ocyurus chrysurus. The bromophenols were extracted by steam distillation with pentaneether (7:3 v/v), identified by reverse phase High Performanc...
متن کاملMercury concentrations in common carp (Cyprinus carpio) tissues, sediment and water from fish farm along the Karoun River in Iran
The Karoun River is major source of water for warmwater fish culture industry in southwest of Iran. The aim of the present study was to investigate the distribution of mercury in tissues of marketable common carp and in bottom sediments of fish farms in Khouzestan province. This study was carried out on 45 fish farms that are located on the bank of the Karoun River in Khouzestan province, sout...
متن کاملForest owner incentives to protect riparian habitat
Private landowners increasingly are asked to cooperate with landscape-level management to protect or enhance ecological resources. We examine the willingness of nonindustrial private forest owners in the Pacific Northwest (USA) to forego harvesting within riparian areas to improve riparian habitat. An empirical model is developed describing owners’ willingness to accept an economic incentive to...
