Patrick Nichols @saltwaterpatrick.bsky.social · 25/09/2026Rainy season in the subarctic 🌧️ ☔ We're harnessing it all to detect forest-dwelling creatures 🦉 #NORTHDIVeRSITY #eDNA #science 020
Reposted by Patrick NicholsDr. Nyssa Silbiger @nsilbiger.bsky.social · 25/09/2026New paper! 🪸🌊 As reefs shift, the communities that replace corals can reshape the chemical environment around them. Laurel shows how community metabolism creates “chemical legacies” that alter coral physiology. @aslo.org aslopubs.onlinelibrary.wiley.com/doi/10.1002/...aslopubs.onlinelibrary.wiley.comCommunity metabolism generates chemical legacies that alter coral physiologyCoral reefs are among the world's most diverse ecosystems and contribute substantially to ocean productivity and the carbon budget. Disturbances are shifting reefs to altered community states, yet ho... 0135
Patrick Nichols @saltwaterpatrick.bsky.social · 04/09/2026Set up a tarp in the forest, catch rain running off the canopy, collect the throughfall with our 3D-printed sampler. Simple as that. We're using OMNIeDNA CANOPY to find out what's living above us... just from rain washing off leaves and bark. 🌲🧬 #eDNA #CitizenScience #Biodiversity #NORTHDIVeRSITY 040
Patrick Nichols @saltwaterpatrick.bsky.social · 03/09/2026Testing our open-source 3D-printed OMNIeDNA TORRENT sampler in Finnish rivers Simple, efficient, and designed for anyone to use... we're democratizing eDNA biomonitoring from the Baltic to boreal streams. 🔬🧬 #eDNA #OpenScience #Biodiversity #CitizenScience #Finland #NORTHDIVeRSITY 021
Patrick Nichols @saltwaterpatrick.bsky.social · 28/07/20262 yrs of eDNA on Hawaiian reefs shows a persistent core (sponges, annelids, algae) anchors site identity. Rare taxa drive temporal noise (wind/waves/tides). eDNA = stable communities, not just transient DNA. Spatial > temporal. #eDNA #biodoversity #coralreefs 📄 doi.org/10.1111/mec.... 021

Monitoring key species under industrial pressure using simple DNA tests from a moving boat to inform conservation.

Patrick Nichols @saltwaterpatrick.bsky.social · 29/06/2026Off to sea soon! ⛵️ Built this eDNA sampling planner to figure out how many sites I can actually sample before I go. Play with the parameters & plan smarter. Free to use! pknichols.com/ednabler/ #eDNA #MarineScience #Fieldwork #NORTHDIVeRSITY 070
Patrick Nichols @saltwaterpatrick.bsky.social · 23/06/2026I'm tired of seeing conservation efforts bottlenecked by the cost of fancy equipment. So, we went back to the drawing board. If we want to protect biodiversity, we need tools that can be deployed at scale. Fewer bells and whistles. More data. #eDNA #Biodiversity #Conservation #NORTHDIVeRSITY 130
Patrick Nichols @saltwaterpatrick.bsky.social · 07/05/2026Just wrapped #BioMonWeek26 on democratizing eDNA. Passive samplers (PEDS) for invasive algae + detection of endangered seals & otters. Simple, scalable, no-frills filtration. Let's make molecular biomonitoring more accessible!! 🧬 020
Patrick Nichols @saltwaterpatrick.bsky.social · 09/04/2026eDNA flagged Chondria tumulosa far beyond Hawaiʻi, but multilocus sequencing revealed a cryptic sister lineage, not range expansion. Takeaway: “false positives” in eDNA can reflect hidden diversity, not detection error. Single-locus markers ≠ enough. #eDNA #CrypticSpecies #InvasionBiology 110
Patrick Nichols @saltwaterpatrick.bsky.social · 24/11/2025Winter has arrived. Commuting through the snowy wonderland is quite the change of pace! 010
Patrick Nichols @saltwaterpatrick.bsky.social · 26/08/2025After nearly a decade studying marine biology in Hawai‘i and earning two degrees at UH Mānoa, it’s time for a new chapter. Grateful for all the lessons, mentors, and aloha that shaped me here. Excited to begin a postdoc in applied conservation and genomics — a hui hou, Hawai‘i🌊#PhDone 020
Patrick Nichols @saltwaterpatrick.bsky.social · 25/08/2025Can we circumvent the cumbersome filtration of #edna from seawater to detect rare taxa? Yes! Passively deploying simple cost-effective cotton membranes can, with trade-offs of course. @sednasociety.bsky.social doi.org/10.7717/peer... 084
