2026-02-02 – Weekly Biology News : Lyrebirds mimic chainsaws

Last week in the Biology community, members engaged in a wide range of discussions, reflecting the diverse interests of our forum. The conversation on effective eDNA courses for coastal surveys was particularly vibrant, with members sharing their experiences and recommendations. Environmental concerns were a significant theme, as seen in the detailed thread about the impact of 6PPD-quinone in stormwater on coho salmon. Additionally, members explored innovative ways to maintain tranquility in the lab environment and shared fascinating insights into animal behavior, especially lyrebirds’ unique vocal mimicry.

Looking forward to another week of engaging discussions. Whether you’re contributing or just reading along, your involvement makes this community what it is.

On our last coastal eDNA run, pre-loading sterile 0.45 µm filters and getting them on ice within 2 hours halved dropouts — always bring a ‘field blank’ because contamination spreads like glitter. Courses help, but a quick mock survey before the real tide window taught us more; anyone tried Longmire’s buffer instead of freezing on site?

@liatorr, I’ve found that using a larger volume of water for filtration can really improve eDNA yields, kind of like trying to catch more fish with a bigger net. Just make sure your filters can handle it without clogging! How’s your team tackling contamination issues?

I’ve found that getting those eDNA samples on ice fast is crucial — like keeping ice cream from melting at a summer picnic! Also, using a personal sterile jar for your samples can avoid cross-contamination; it’s all about keeping things tidy in the field.
