Check out our new paper in @molecology which explores how #CRSIPR can be used for targeting #DNA #barcodes, entire #chloroplast #genomes, and the relative #abundance of species in a sample. Read here: buff.ly/4aPeCLf 🧬🥼 @Brown_IBES
CRISPR technology offers an exciting opportunity for targeted sequencing in biodiversity science. Curious how DNA barcodes and entire chloroplast genomes can be enriched using CRISPR methods and without the need for PCR? Read: buff.ly/4aPeCLf
🧵 1/3

ALT A diagram outlining the difference between PCR and CRISPR based pipelines for DNA barcoding. Unlike PCR-based approaches where PCR reagents must successfully amplify target regions and sequenced on a lab-based sequencer, CRISPR based approaches enrich target regions using the CRISPR-Cas complex and sequenced using portable sequencing technologies (e.g., ONT). Where PCR-based approaches may be laborious and require expensive equipment, CRISPR-based methods are faster, more versatile and precise.

Using a series of experiments, @BethanColquhoun and @tyler_kartzinel show #CRISPR can be used to target diagnostic #DNAbarcodes (>1,000 bp) and entire #chloroplast #genomes (>120,000 bp) in single- and mixed-species samples: bit.ly/CRISPRtargetseq

So thankful to have @lsweyrich join @EEB_Brown today and give an incredible seminar! Great to think about how the evolutionary histories of our microbiomes can help shape modern medical practices. Thanks for joining us, Laura 🙏🏼
Exciting @EEB_Brown departmental seminar today, about the evolutionary history of the human #microbiome, by @lsweyrich.

PhD projects to study dolphins social behaviour available in my lab @UQscience with @sb_dolphins. If interested DM me or email me. Scholarships open end of February! Open to National and International applicants!
The goals of #conservation biology often center around taxonomy, ecology, and genetics…but what about #microbiomes?
Our latest paper looks at koala gut microbiomes and genetics! 🐨🦠🧬💩

We show:
1) koala gut microbiomes show large variability across the landscape
2) koala landscape microbial patterns do not match landscape population genetic patterns (genetics are often considered when designing koala conservation initiatives)

So, could microbiome research could help us better understand natural variation, the composition, structure, and function of living systems, and how to maintain the resilience and ability of living systems to persist over time? We think so!

🚨Review the controversy around abundance filtering in #DNAmetabarcoding. Develop intuition. Ponder Yellowstone bison and bighorn sheep diets 🦬🐑
Read our review in @molecology 👇🏼

@tyler_kartzinel @PTFreeman +others
What does it mean to be ‘conservative’ with dietary DNA metabarcoding data? Popular strategies may do more harm than good, according to a perspective by @BethanColquhoun et al.
Review the controversy. Develop intuition. Ponder Yellowstone bison diets. Read buff.ly/32qpyRi
So many people (including many students from @EEB_Brown) contributed to this review and I'm so grateful for their collaboration and input!
We hope this review will lead to open-discussions in #DNAmetabarcoding about how to best deal with low-abundance reads. Transparency is key!

Can abundance-filtering in #DNAmetabarcoding influence ecological interpretation? Simple answer: yes! Long answer: it's complex. Check out our new paper to find out more and see some solutions that may help us navigate this issue!
