Macroinvertebrates, Heavy Metals and PAHs in Urban Watercourses [PDF]

open access: yes, 2001
Good quality stream water and sediments are crucial for the support of healthy stream flora and fauna but urban runoff degrades watercourses leaving a legacy of pollution in the stream sediments.

Assessing the freshwater quality of a large-scale mining watershed : the need for integrated approaches [PDF]

open access: yes, 2019
Water quality assessments provide essential information for protecting aquatic habitats and stakeholders downstream of mining sites. Moreover, mining companies must comply with environmental quality standards and include public participation in water ...

Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

Pre-impoundment Limnological Study of the Strawberry River in Northeastern Arkansas [PDF]

open access: yes, 1971
A study of pre-impoundment limnological characteristics of the Strawberry River was made from August, 1967 to June, 1968. Two collecting stations were established, one upstream which would not be inundated and a lower station which would be inundated ...

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

open access: yesJournal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Aquatic biosurvey of the Lovell River on UNH land [PDF]

open access: yes, 2003
We assessed the physical, chemical and biological conditions at two sites along the Lovell River on University of New Hampshire (UNH) -owned conservation land. The discharge was 4.4 m3 s-1 at Site 1 and 5.7 m3 s -1 downstream at Site 2.

Benthic and interstitial habitats of a lentic spring as invertebrate refuges during supra-seasonal drought [PDF]

open access: yes, 2013
Instream refuges are places where invertebrates persist during disturbances due to reduced adverse impacts. During droughts, low flows may be accompanied by elevated temperatures, and potential refuges including subsurface sediments and spring-fed ...

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

open access: yesJournal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

A comparison of results from previous and present investigations of benthic macroinvertebrates in the small and shallow Lake Shoji, Fuji Five Lakes, Japan

open access: yesFauna Norvegica, 2012
In order to clarify the current status of the benthic community of Lake Shoji, and to examine the difference with the last quantitative data of the lake by Miyadi (1932) and Kitagawa (1973), the distribution of benthic macroinvertebrates in this lake was
