Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path ForwardNARA Subscribed
Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy. Underwater fish observation (UFObs) techniques, such as Underwater Visual Census (UVC), stereo‐Baited Remote Underwater Video (stereo‐BRUV) and Remotely Operated Vehicles (ROVs), play...
Sexually attractive males produce relatively more sons in an externally fertilising fishNARA Subscribed
According to the mate attractiveness hypothesis of biased progeny sex-ratio, sexually attractive males should produce relatively more sons. We tested this hypothesis with three-spined sticklebacks Gasterosteus aculeatus , a fish species with external fertilisation, in which the intensity of red breeding coloration is a sexually selected trait. We used reflecto-spectrophotometry and visual modelling to assess red breeding color...
To advance understanding of meiofauna, key components of marine benthic ecosystems, an international team conducted a morphology-based taxonomic survey and workshop around São Miguel, the largest Azorean island, in 2019. The survey yielded critical baseline data on meiofaunal diversity and, despite taxonomic challenges that limited identification of certain taxa, laid a solid foundation for further research. To expand these fi...
Bermudagrass is widely grown in the southern United States for its superior turfgrass quality and wear tolerance. However, inferior shade tolerance is a major limitation, especially in home lawns, parks or other landscapes where shady areas are prevalent. The identification of new sources of shade tolerance is key in development of cultivars with improved performance for this trait. In this study, 24 accessions collected from...
Plankton communities today and tomorrow—potential impacts of multiple global change drivers and marine heatwavesNARA Subscribed
In the context of global change, marine organisms are subjected not only to gradual changes in abiotic parameters, but also to an increasing number of extreme events, such as heatwaves. However, we still know little about the influence of heatwaves on the structure of marine communities, and experimental studies are needed to test the impact of heatwaves alone and in combination with other environmental drivers. Here, we condu...
Consistent Unimodal Body Length Distributions in Hundreds of Reef Fishes Across Diverse Life HistoriesNARA Subscribed
Animal body size distributions result from interactions of growth, mortality and recruitment. In ecology and fisheries science, theoretical models of fish body size distributions are widely used but rely on life‐history parameters—growth coefficient (K) and natural mortality rate (M)—that remain unknown for most species and are challenging to estimate. Analysing data from underwater visual surveys and exhaustive sampling, repr...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Adaptive variation in opsin expression of sticklebacks from different photic habitatsNARA Subscribed
We studied phenotypic and genetic adaptation of the visual system of three-spined sticklebacks, Gasterosteus aculeatus , from North Uist, Scotland. We quantified differences in opsin gene expression of the four cone opsin genes among wild-caught fish from three lakes with clear and from three with tea-stained water and their offspring that were raised in clear water. In addition, visual sensitivity of wild-caught fish was mode...
Climate change impacts on a sedimentary coast—a regional synthesis from genes to ecosystemsNARA Subscribed
Climate change effects on coastal ecosystems vary on large spatial scales, but can also be highly site dependent at the regional level. The Wadden Sea in the south-eastern North Sea is warming faster than many other temperate coastal areas, with surface seawater temperature increasing by almost 2 °C over the last 60 years, nearly double the global ocean mean increase. Climate warming is accompanied by rising sea levels, which...
