Abstract

Climate change has led to intensification and poleward migration of the Southeastern Pacific Anticyclone, forcing diverging regions of increasing, equatorward and decreasing, poleward coastal phytoplankton productivity along the Humboldt Upwelling Ecosystem, and a transition zone around 31° S. Using a 20-year dataset of barnacle larval recruitment and adult abundances, we show that striking increases in larval arrival have occurred since 1999 in the region of higher productivity, while slower but significantly negative trends dominate poleward of 30° S, where years of recruitment failure are now common. Rapid increases in benthic adults result from fast recruitment–stock feedbacks following increased recruitment. Slower population declines in the decreased productivity region may result from aging but still reproducing adults that provide temporary insurance against population collapses. Thus, in this region of the ocean where surface waters have been cooling down, climate change is transforming coastal pelagic and benthic ecosystems through altering primary productivity, which seems to propagate up the food web at rates modulated by stock–recruitment feedbacks and storage effects. Slower effects of downward productivity warn us that poleward stocks may be closer to collapse than current abundances may suggest.

DATA & FILE OVERVIEW

File included: Barnacle_Recruitment_Data_for_Long-Term_Analyses_cleaned.csv

Comma-separated values file containing long-term barnacle recruitment records.

Number of rows: 12,930 data rows

Number of variables: 24 columns

General structure: Each row represents a recruitment-plate observation associated with site, date, plate identifier, deployment duration, taxonomic counts, geographic region, and period classification.

Relationship between files: Single data file.

No separate ancillary file included in the current data package.

METHODOLOGICAL INFORMATION

Data collection method: Larval recruitment was monitored using 10 × 10 cm Plexiglas plates covered with SafetyWalk 3M.

Method from associated publication.

Study system: Rocky-shore intertidal barnacles, primarily Jehlius cirratus and Notochthamalus scabrosus.

Study sites: Eleven primary sites along 29-34°S; subset of 19 exposed rocky-shore sites monitored over multiple years.

Analytical standardization: Because plate exposure duration varied, recruitment rates used in the associated publication were standardized by days in the field and expressed as individuals per 100 cm² per day.

Exposure-duration filter used in paper: Collectors exposed for fewer than 15 days or more than 45 days were excluded from the main analyses.

The uploaded CSV includes both records within and outside this analytical window.

DATA-SPECIFIC INFORMATION FOR: Barnacle_Recruitment_Data_for_Long-Term_Analyses_cleaned.csv

Missing data codes: Empty cells

Empty cells represent missing, unavailable, not recorded, or not applicable values.

Zero values: 0

Numeric zero values should be interpreted as observed counts of zero individuals, cyprids, recruits, or other recorded categories. Zeros are distinct from empty cells.

Exposure range check: 11,514 records within 15-45 days; 1,416 outside this range; 35 with days < 15; 1,381 with days > 45.

Relevant for reproducing the associated publication.
