1/n Are trained scientists required to collect data? Can we trust data from citizen scientists? After all, we could sure use all the biodiversity data we can get, given the changes wrought by the Anthropocene. NEW PAPER ALERT:

The state of biodiversity for most of the world is largely enigmatic due to a lack of long-term population monitoring data. Citizen science programs could substantially contribute to resolving this...

So. Much. Ratio. BTW, it's not the sentiment, it's the virtue signaling from a company that charges $12,290 to publish an open access paper in their flagship journal. For reference, average annual salary in the Global South is around $18,000.
Stop using ‘summer’, ‘winter’ and the rest when inviting researchers to events — it’s a small step, but it’s necessary and inclusive

In collaboration with @Scripps_Ocean @calcofi @noaaocean @microcean @Rovingdiver2 @GarfieldKwan we found that selective feeding and larger size-at-birth led to larger larval rockfish size, faster growth, and greater survival https://t.co/mBcQ11ftgD

Do you know of any study that quantifies intrasample variability in deltaN15, deltaC13 of fish fin tissue (or any other tissue) based on repeated measures? Beyond analytical error (based on standards). And not comparing different tissue types.

PhD chapter publication alert! Erica Mason's work here shows, across multiple decades, how both sporadic recruitment and harvest at spawning aggregations intensify/steepen/shorten boom and bust cycles in a critically important recreational fishery.
Sporadic recruitment & efficient harvest on #SpawningAggregations lead to multidecadal fluctuations in fishing opportunity for a popular fishery. What does #FisheryRecovery look like following more than a decade of collapse? #BarredSandBass
