#Northumberland coast, blow away the cobwebs and clear the mind.

Dark forces are preventing us fighting the climate crisis – by taking knowledge hostage | George Monbiot www.theguardian.com/commentisfre...

Transfer of genetic material from domesticated to wild salmon populations through fish farm escapes & interbreeding, is a significant risk to wild salmon populations. Identifying this pressure in wild populations requires the use of informative markers. New paper link.springer.com/article/10.1...

We do not have deliberate and politically driven reductions in long-term govt. science programmes in the UK. Nevertheless, budgetary constraints and a requirement to focus on immediate policy and regulatory data requirements are affecting the freswater data landscape nonetheless.

From NASA to the National Institutes of Health, federal agencies conduct research that universities cannot. Agency scientists speak with Nature about the irreplaceable facilities, institutional knowledge, and training opportunities that the country is losing. 🧪

I’m delighted to share that our latest research has just been published in HESS. We developed an unsupervised workflow to estimate river surface velocities from videos. Testing on 11,000+ videos against 274 gauging measurements showed excellent agreement. hess.copernicus.org/articles/29/...

New paper on effects of captive rearing of Atlantic salmon on body morphology in context of stocking "Humanity often tries to engineer its way out of environmental crises. But nature isn’t easily replaced. Sometimes, the best solution is to give it the space to recover on its own" bit.ly/4oykzmy

A fantastic job opportunity for someone to work at the interface between Atlantic salmon habitat modelling and management. Cutting edge research as part of an excellent project team.

New recommendations for water regulation in England and Wales. In Scotland of course the water industry is publicly owned through Scottish Water.

1. Accurate (unbiased and precise) quality controlled data are essential for understanding and monitoring trends in river temperature. However, researchers often collate and analyse data without consideration of these issues. A new 📜 & summary🧵 onlinelibrary.wiley.com/doi/10.1002/...

Do poor growth conditions at sea result in salmon returning to rivers to spawn at a younger or older age? New study shows that that rapid growth can lead to later maturation but maturation age can be influenced by shifts in growth during the marine migration link.springer.com/article/10.1... 🐟

1. Are you interested in assessing the status of Atlantic #salmon and brown #trout populations using electrofishing data? If so then this 🧵 is likely to be of interest to you. The latest report from the National Electrofishing Programme for Scotland #NEPS was published this week bit.ly/4jNrXH6 🧪🌎

Up above Loch Tummel. Time to go hunt for that pot of gold.

River temperature forecasts are likely to be required to inform fisheries management decisions under a rapidly changing climate. Interesting new paper: hess.copernicus.org/articles/29/...

Protection & creation of riparian woodland is one of the few management options available to mitigate river temperature increases under climate change. "riparian buffers wider than 15 m protected against water temperature increases..." agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Another day on the Northumberland coast😁

Why the hell doesn't Starmer do this about Farage...

Unwinding on the Northumberland coast. Beach walks, dogs, beer, food. Is there a better tonic?

"...we provide an updated global assessment of farmed salmon escape policies. Our findings reveal a rapid rise in the spread & implementation of escape regulations globally & the development of new technologies that aim to address this problem. www.sciencedirect.com/science/arti...

An improvement in freshwater biodiversity in England's rivers in the 1990s and early 2000s was linked to reduced zinc and copper pollution as coal use and heavy industry declined, say researchers. Read more about a new UKCEH-led study: www.ceh.ac.uk/press/biodiv... #rivers #WaterQuality 🧪 1/

It can be challenging to design and implement freshwater fish assessment methods at international scales due to differences in sampling methodologies and habitat characterisation. Here we consider opportunities to harmonise data to inform sea trout assessments doi.org/10.1002/aqc....

Juvenile chinook dispersal patterns identified through genetics "temperature was a dominant driver of dispersal, with individuals originating from warmer sections of the mainstem typically moving to cooler mainstem sections or tributaries" movementecologyjournal.biomedcentral.com/articles/10....

The Lancet, considered by some to be the world's leading medical journal (no, it is not a radical-Marxist-left-wing-rag), is living up to its well-deserved reputation and is not mincing words about the Musk administration's actions and their consequences: www.thelancet.com/journals/lan...

"...predicted dispersal patterns can carry significant uncertainties, arising from factors such as the accuracy of the driving hydrodynamics, PTM resolution, stochasticity of dispersal simulations, & parameterisation of the behavioural characteristics of the particles" doi.org/10.1016/j.ec...

Wild Atlantic #salmon populations are in decline across their native range. In Scotland, "spring" stocks are of particular concern. Understanding population processes & drivers of change can inform management action. Detailed long-term monitoring provides these insights tinyurl.com/Girnock-and-...

Important new paper on spatial & temporal variability of #introgression of farmed fish into wild Canadian #Atlantic #salmon rivers: "larger rivers with higher numbers of wild salmon consistently had lower proportions of hybrids than several of the smaller rivers" link.springer.com/article/10.1...

A Review from Haase et al summarizes freshwater conservation efficacy. Freshwater conservation appears to have lower frequency of positive outcomes compared to marine and terrestrial conservation. The authors offer insights for improvement in the future! go.nature.com/4h4oKm1

Characterising spatially and temporally heterogeneous groundwater and hyporheic exchange processes is extremely challenging. As a result these processes are often poorly represented, ignored or poorly parameterised in process based river temperature models. www.jstage.jst.go.jp/article/ras/...

Temperature, discharge and hydraulics can affect fish migration, spawning distribution and timing. Interesting study on the effects of climate change on suitability of upstream migration conditions for several diadromous species. cdnsciencepub.com/doi/10.1139/...

Forecasting river temperature is likely to become increasingly important in a warming climate, informing management decisions in activities as diverse as electricity generation and angling. Interesting new paper: www.mdpi.com/2306-5338/12...

New years hike up on the Ghlo range, #Perthshire #Scotland

"differences [in migration speed] are related to changes in local ocean conditions: years with lower on-shelf salinity, stronger on-shelf northwest currents, and stronger shelf-edge currents were associated with greater migration success" academic.oup.com/icesjms/adva...

Characterising hyporheic fluxes is always challenging! link.springer.com/article/10.1...

That's my "X" account deactivated. No going back now. Such a shame what's happened there. "Twitter" used to be a great platform to share and discover science and have informative and respectful conversations. I hope Bluesky continues to be a place for these types of interactions.
