Freshwater fishes of the Waterberg aquatic ecoregion, South Africa: Diversity, taxonomic conflicts and conservation concerns

open access: yesJournal of Fish Biology, EarlyView.
Abstract Southern Africa is a region denoted by both high levels of fish diversity, some of it cryptic and unrecognised by current taxonomy, and severely threatened freshwater ecosystems. The Waterberg, a key aquatic ecoregion of the greater Limpopo River basin in South Africa, represents an area with high terrestrial conservation value but is lacking ...

Dynamic colour change predicts movement behaviour in a diadromous fish

open access: yesJournal of Fish Biology, EarlyView.
Abstract Dynamic changes in colour and pattern facilitate key behavioural functions in animals, particularly camouflage for predator avoidance. However, the benefits of colour change depend on the environmental and behavioural contexts. We tested how colour change interacts with movement behaviour in a freshwater fish by filming individuals in an open ...

Changes in size‐at‐age of juvenile Atlantic salmon cohorts over the past 50 years and linkages to environmental factors

open access: yesJournal of Fish Biology, EarlyView.
Abstract Quantifying the potential effects of climate change on juvenile salmonid body length at a large spatiotemporal scale is challenging given the multitude of biological processes and methodological constraints. In the present work, we analysed potential changes in size‐at‐age of juvenile Atlantic salmon cohorts over the past 50 years in the ...

Transnational film production and the tourist gaze : on Hou Hsiao-hsien’s Café Lumière and Flight of the red balloon

open access: yes, 2018
This article attempts to reexamine the multiple forms of displacement in and of the film to which the new historical era gave rise, and thereby critically engage with the questions of transnational capital flow, global tourism and spectatorship, and ...

Distributional patterns and habitat associations of sturgeon chub in western Missouri River tributaries of South Dakota

open access: yesJournal of Fish Biology, EarlyView.
Abstract There is a growing body of literature that suggests riverine fish are some of the most threatened taxa on a global scale. Similarly, the literature suggests less‐altered tributaries may offer refugia for large‐river specialists. The greater Mississippi River basin, including the Missouri River system, has been subjected to anthropogenic ...

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

open access: yesJournal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.
