Purpose Worksite health promotion programs (WHPPs) are able to promote a healthier lifestyle for blue-collar workers in freight transport, yet their participation is generally low. This study aims to identify different health lifestyle classes among blue-collar workers in freight transport and investigate the relationship between class membership and WHPP participation. Methods Data from 16,897 employees were obtained from an...
A multi‐proxy record of climate variability during the Loch Lomond Stadial (GS‐1) at Old Buckenham Mere, East England, UKNARA Subscribed
Northwest Europe experienced high‐amplitude climate change at the onset and end of the Younger Dryas (YD; ca 12 800–11 600 cal a BP), a crucial period to develop our understanding of natural climate dynamics. European palaeoclimatological records generally suggest a bipartite structure of the YD, potentially due to a northward retreat of the polar front around 12 100 cal a BP. However, several recent studies have shown more co...
The effect of climate at origin on Douglas-fir growth, leaf traits and embolism resistance along a rainfall gradient in Central EuropeNARA Subscribed
Key message In Douglas-fir grown in Central Europe, growth and specific leaf area differed between coastal and interior provenances but little intra-specific variability was found for the Huber value and xylem safety. Abstract In Central Europe, the economically most important timber species for roundwood production, Norway spruce, has been severely affected by recent global change-type drought events. Due to its large spatial...
Geography and ecology shape the phylogenetic composition of Amazonian tree communitiesNARA Subscribed
Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location Amazonia. Taxon A...
Promoting effects of aluminum addition on chlorophyll biosynthesis and growth of two cultured iron‐limited marine diatomsNARA Subscribed
Aluminum (Al) may play a role in the ocean's capacity for absorbing atmospheric CO 2 via influencing carbon fixation, export, and sequestration. Aluminum fertilization, especially in iron (Fe)‐limited high‐nutrient, low‐chlorophyll ocean regions, has been proposed as a potential CO 2 removal strategy to mitigate global warming. However, how Al addition would influence the solubility and bioavailability of Fe as well as the phy...
Switches between nitrogen limitation and nitrogen–phosphorus co‐limitation in the subtropical North Atlantic OceanNARA Subscribed
Concentrations of bioavailable inorganic nitrogen (N) and phosphorus (P) are simultaneously depleted in the (sub)tropical North Atlantic Ocean, but it remains unclear if phytoplankton growth rates are N limited or N–P co‐limited. Here we present findings from three bottle‐scale experiments using a four‐by‐four matrix of low‐level N and P additions, conducted at one site in the subtropical North Atlantic Ocean. Phytoplankton re...
Phytoplankton community response to episodic wet and dry aerosol deposition in the subtropical North AtlanticNARA Subscribed
Atmospheric aerosol deposition into the low latitude oligotrophic ocean is an important source of new nutrients for primary production. However, the resultant phytoplankton responses to aerosol deposition events, both in magnitude and changes in community composition, are poorly constrained. Here, we investigated this with 19 d of field and satellite observations for a site in the subtropical North Atlantic. During the observa...
