Kiwi, population modeling, Rstats, fish stock assessment, data wrangling, plus any shiny distraction from what I should be doing.
17 years of volunteer bird counts at Brook Waimārama Sanctuary show what predator eradication delivers: robin numbers up 17×, tomtit up 18×, tūī 3×, bellbird 2.3× since 2017. New paper w/ K. Chamberlain, Notornis. doi.org/10.63172/244...

New in ICES journal: length–weight relationships for Pacific yellowfin tuna aren't fixed — they vary by region, season, depth & bait. We find a "linear safe zone" (98–161 cm) and show data source matters more than model form for biomass estimates. Open access 🐟 doi.org/10.1093/ices...
Spatiotemporal variation in the length–weight relationship of Pacific yellowfin tuna reflects biological and fishery factors and affects aggregate weight estimation
Abstract. Length–weight relationships (LWRs) underpin biomass estimation in tuna stock assessments, yet they are typically treated as spatially and tempora
