Are warmer oceans good or bad for #fish? 🐟 The answer is a dangerous paradox. Our new paper in @natecoevo.nature.com shows how marine heatwaves may create “fake” fish gains that mask a large-scale crash. Read our findings here: www.nature.com/articles/s41...

Chronic ocean heating fuels ‘staggering’ loss of marine life, study finds Fish levels fall by 7.2% with as little as 0.1C of warming per decade, northern hemisphere research shows

Estimating global bee species richness and taxonomic gaps - Nature Communications Bees are crucial for the maintenance of healthy ecosystems, yet rigorous estimates of their species’ richness are lacking. This study estimates taxonomic gaps for bees around the world and provides a ...

New paper alert! "Estimating global bee species richness and taxonomic gaps" suggests that we have thousands of bee species left to describe and decades of taxonomic work ahead of us. We also provide the methods needed to apply more broadly :)

Screening, sorting, and the feedback cycles that imperil peer review The process of peer review is vital to contemporary science, but is also under enormous strain. This study uses mathematical models to dissect the threats to the long-term viability of peer review, su...

1. Kevin Gross and I have a new paper out today PLOS Biology.

We used economic models based around screening games and the market for unpaid labor to highlight a meltdown cycle threatening peer review.

A comparison of protocols for isolating and extracting host DNA from caribou (Rangifer tarandus) fecal pellets - Conservation Genetics Resources Conservation Genetics Resources - Fecal samples are valuable for wildlife genetic studies where invasive tissue sampling is difficult, expensive, or negatively impacts welfare. However, fecal DNA...

Congrats to Samantha Barrette for publishing her honours thesis! 🎉👏 While are many ways to get host DNA from fecal pellets, the effectiveness of different approaches is rarely compared. We tackled this in caribou using a full factorial design and a new qPCR assay: link.springer.com/article/10.1...

Degradation of fish food webs in the Anthropocene The decrease in body size driven by the selective species turnover is widely altering fish food web topology and function.

New paper out examining fish food web degradation in the Anthropocene. We show the structure of aquatic food webs are changing-- even when species richness doesn’t. These signals are strongly associated with decreases in body size within fish communities. www.science.org/doi/10.1126/... 🌐🐠🐡🦈🐟

The Importance of Effective Population Size in Conservation and Biodiversity Monitoring Effective population size (Ne) is a key concept in biology and conservation. Stripped to its bare essentials, it reflects how much genetic drift a population experiences, expressed as a number of ind...

We have compiled a special issue for @evolappjournal.bsky.social on Effective population size in Conservation and Biodiversity Monitoring, dedicated to the late Michael W. Bruford.
This SI is a must read for everyone who struggles with what "effective population size" means.

We are seeking to appoint four full-time field assistants to work on the Wytham Tit Project for 4-8 weeks in spring 2026. Two 8-week field assistants will join the nest monitoring team; duties for these posts will include (i) collecting standardised data from nest-box breeding populations of blue and great tits, (ii) catching and ringing parent birds, (iii) ringing nestlings, and (iv) inputting data collected in the field. These positions with run from approximately Tuesday 7th April to Monday 1st June. Successful candidates for these positions must have (or be qualified to obtain) a BTO permit to ring adult great tits and blue tits. A further two field assistants will be hired to support a project collecting behavioural (foraging) data for great tits breeding in the Wytham population. These roles will involve a significant amount of nightwork. Duties will include (i) setting up and calibrating electronic tracking equipment and nest box cameras in the field, (ii) mapping tracking equipment locations using GPS, (iii) helping with catching and ringing parent birds and fitting tracking devices, (iv) assisting with mistnetting to re-trap tagged parents, and (v) inputting data collected in the field. These positions with be approximately 7 and 4 weeks in duration, starting from 13th April and 4th May, respectively. Possession of a BTO ringing permit with misnet endorsement and driving license are highly desirable for these roles. All fieldwork will take place in Wytham Woods, near Oxford. All Successful candidates must be able to demonstrate skill and enthusiasm for biological research as well as experience of fieldwork under arduous conditions, and both lone work and working as part of a team. Due to the short-term nature of these posts, successsful applicants must already have the right to work in the UK. Salary & Accommodation: Field assistants will be paid at grade 5.2 (£17.37/hour). Contact eleanor.cole@Biology.ox.ac.uk

We are hiring at the Wytham Woods for the upcoming field season. 4 roles available. Please share with anyone who might be interested. #UKbirds #birdringing
