Environmental DNA (eDNA) metabarcoding is emerging as a novel, objective tool for monitoring marine metazoan biodiversity. Zooplankton biodiversity in the vast open ocean currently monitored through continuous plankton recorder (CPR) surveys, using ship-based bulk sampling and morphological identification. We assessed whether eDNA (2 L filtered seawater) could capture similar Southern Ocean zooplankton conventional CPR (~1,500 seawater per sample). directly compared with (a) (b) of collected...
Plankton are the base of marine food webs, essential to sustaining fisheries and other life. Continuous Recorders (CPRs) have sampled plankton for decades in both hemispheres several regional seas. CPR research has been integral advancing understanding dynamics informing policy management decisions. We describe how can contribute global diversity monitoring, being cost-effective over large scales providing taxonomically-resolved data. At OceanObs09 an integrated network surveys was envisaged...
Macroecological relationships provide insights into rules that govern ecological systems. Bergmann's rule posits members of the same clade are larger at colder temperatures. Whether temperature drives this relationship is debated because several other potential drivers covary with temperature. We conducted a near‐global comparative analysis on marine copepods (97 830 samples, 388 taxa) to test rule, considering drivers. Supporting we found better predicted size than did latitude or oxygen,...
DNA metabarcoding is an efficient method for measuring biodiversity, but the process of initiating long-term DNA-based monitoring programmes, or integrating with conventional programs, only starting. In marine ecosystems, plankton surveys using continuous recorder (CPR) have characterized biodiversity along transects covering millions kilometres time-series spanning decades. We investigated potential use in CPR surveys. Samples (n = 53) were collected two Southern Ocean and metazoans...
We provide an analysis of zooplankton distributions in the circumpolar Southern Ocean based on samples collected by international SCAR Continuous Plankton Recorder Survey (SO-CPR). analysed SO-CPR measurements relation to satellite and oceanographic model hind-cast data over period 1997–2018. These environmental were chlorophyll-a concentration, net primary productivity (VGPM model), sea-surface temperature (SST), mixed layer depth, sea ice spatial gradient SST (as indicator ocean fronts)....
Planktonic Foraminifera are unique paleo-environmental indicators through their excellent fossil record in ocean sediments. Their distribution and diversity affected by different environmental factors including anthropogenically forced climate change. Until now, historical changes have not been fully assessed at the global scale. Here we present FORCIS (Foraminifera Response to Climatic Stress) database on foraminiferal species from 1910 until 2018 published unpublished data. The includes...
The Southern Ocean surrounding Antarctica harbours some of the most pristine marine environments remaining, but is increasingly vulnerable to anthropogenic pressures, climate change, and invasion by non-native species. Monitoring biotic responses cumulative impacts requires temporal spatial baselines ongoing monitoring - traditionally, this has been obtained continuous plankton recorder (CPR) surveys. Here, we conduct one longest environmental DNA (eDNA) transects yet, spanning over 3000...
Abstract Marine zooplankton time series are crucial to understand the dynamics of pelagic ecosystems. However, most observational only a few decades long, which limits our understanding long-term dynamics, renders attribution observed trends global change ambiguous, and hampers prediction future response environmental change. Planktonic foraminifera calcifying marine that have unique potential substantially extend view on plankton because their skeletal remains preserved for millions years...
Macroecological relationships provide insights into rules that govern ecological systems. Bergmann’s Rule posits members of the same clade are larger at colder temperatures. Whether temperature drives this relationship is debated because several other potential drivers covary with temperature. We conducted a near-global comparative analysis on marine copepods (100,326 samples, 388 taxa) to test Rule, considering drivers. Supporting we found better predicted size than did latitude or oxygen,...
