A physical, chemical and biological characterization of river systems is needed to evaluate their ecological quality and support restoration programs. Herein, we describe an approach using water chemistry, physical structure and land use fo...
Sampling Efforts for Estimating Fish Species Richness in Western USA River Sites [0.03%]
美国西部河流鱼类物种丰富度的抽样调查

Fish species richness is an indicator of river ecological condition but it is particularly difficult to estimate in large unwadeable rapidly flowing rivers. Intensive multi-gear sampling is time consuming, logistically complex and expensive...
Benthic macroinvertebrate field sampling effort required to produce a sample adequate for the assessment of rivers and streams of Neuquén Province, Argentina [0.03%]

Soda lakes and pans represent saline ecosystems with unique chemical composition, occurring on all continents. The purpose of this study was to identify and characterise the main environmental gradients and trophic state that prevail in the...
DNA based association and description of the larval stage of Drusus melanchaetes McLachlan, 1876 (Trichoptera: Limnephilidae: Drusinae) with notes on ecology and zoogeography [0.03%]
基于DNA的Drusus melanchaetes McLachlan, 1876(毛翅目: 河蛾科: Drusinae组)幼虫期的关联和描述，并附上生态学和动物区系理论注释
Johann Waringer,Wolfram Graf,Steffen U Pauls et al.
Johann Waringer et al.
At three alpine locations in Switzerland adults of Drusus melanchaetes and unknown Drusinae larvae which could not be identified with existing keys were sampled. Based on DNA association with adults, we identified the unknown larvae as D. m...
Description of the larval stage of Drusus mixtus (Pictet, 1834) (Trichoptera: Limnephilidae: Drusinae) with notes on its ecology and zoogeography [0.03%]
Drusus mixtus（Pictet，1834）（Trichoptera：Limnephilidae：Drusinae）的幼虫阶段描述及其生态和动物地理学笔记
Johann Waringer,Wolfram Graf,Thomas Pitsch et al.
Johann Waringer et al.
In the Swiss Jura adults of Drusus mixtus and unknown Drusinae larvae which could not be identified with existing keys were sampled. Based on ripe pupae, the unknown larvae were identified as D. mixtus. The association was confirmed by spec...
A new fish-based multi-metric assessment index for cyprinid streams in the Iranian Caspian Sea Basin [0.03%]

Species distribution modelling, as a central issue in freshwater ecology, is an important tool for conservation and management of aquatic ecosystems. The brown trout (Salmo trutta) is a sensitive species which reacts to habitat changes indu...
Pressure-specific and multiple pressure response of fish assemblages in European running waters [0.03%]
欧洲流水系统中鱼类群落对压力的特异性和多重压力响应

We classified homogenous river types across Europe and searched for fish metrics qualified to show responses to specific pressures (hydromorphological pressures or water quality pressures) vs. multiple pressures in these river types. We ana...
Natural organic matter and iron export from the Tanner Moor, Austria [0.03%]
奥地利Tanner Moor的天然有机物和铁输出

Franz Jirsa et al.
Samples from a pristine raised peat bog runoff in Austria, the Tannermoor creek, were analysed for their iron linked to natural organic matter (NOM) content. Dissolved organic carbon < 0.45 μm (DOC) was 41-64 mg L-1, iron 4.4-5.5 mg L-1. S...
