Kate Mathers and colleagues describe their latest research which aims to fill a much needed knowledge gap in the effects of artificial floods on subsurface habitats Naturally, river systems and their flow regimes are dynamic, reacting to changing meteorological events such as intense rainfall or annual snowmelt. This hydrological variability is vital in supporting a healthy river system because fluctuating flows regulate sediment transport (gravels … Continue reading Can artificial floods restore ecological health below the riverbed?
Dalal Hanna, aquatic and landscape ecologist, talks about her article reviewing riverine ecosystem service quantification. This paper was on the 2018 list of highly commended papers for this year’s Southwood Prize early career researcher award. An additional video about Dalal’s research is available here. Read the full article, A review of riverine ecosystem service quantification: research gaps and recommendations in issue 55:3 of Journal of … Continue reading Why quantifying riverine ecosystem services matters
Exploring the importance of autocorrelation in flow-ecology management, Associate Editor, Angela Strecker discusses the recent article by Bruckerhoff et al., Flow–ecology relationships are spatially structured and differ among flow regimes. In ecology, it is widely accepted that stream flow is a master variable for fishes. Human alterations to rivers have changed the flow regime significantly, often dampening the natural variability and changing the timing of … Continue reading Go with the flow
Dalal Hanna et. al.’s paper, A review of riverine ecosystem service quantification: Research gaps and recommendations features in issue 55:3 of Journal of Applied Ecology. Watch this video to find out more. ‘Rivers provide numerous ecosystem services, including drinking water and irrigation. They also provide habitat to some our favourite food sources like fish, and places to go for fun recreational activities like swimming. To ensure … Continue reading Video: Riverine ecosystem service quantification
Tributaries, river management and damming. In this post, Associate Editor Tadeu Siqueira comments the recent article by John Sabo and colleagues, Pulsed flows, tributary inputs, and food-web structure in a highly regulated river. The damming of large rivers has been common practice, probably since Thomas Edison built one of the first hydroelectric stations in 1882. Most important rivers in economically developed regions have already been … Continue reading Tributaries may reset the legacy of dams in large rivers
In this week’s blog, Associate Editor, Andre Punt comments on the recent paper by Yamane et al. Tracking restoration of population diversity via the portfolio effect. Many fisheries are managed to avoid populations dropping below threshold levels, and closing them to harvest when this happens. The implications of closures can be substantial for those who gain commercial or recreational benefits from harvest, as well as … Continue reading Tracking restoration of population diversity via the portfolio effect
Issue 54:4’s Editor’s Choice post is written by Shelley Arnott. The article chosen is Critical catchments for freshwater biodiversity conservation in Europe: identification, prioritisation and gap-analysis by Savrina F. Carrizo and colleagues. Aquatic ecosystems around the world are threatened with environmental changes resulting in critical loss of biodiversity; 81% of freshwater populations monitored for the Living Planet Index have declined in abundance between 1970 and … Continue reading Editor’s choice 54:4 – The identification of critical catchments for freshwater conservation
