Disentangling the role of climate and soil on tree growth and its interaction with seed origin.

When considering options for adapting forests under climate change, climate is treated as the dominant driver of forest growth, while soil properties are often ignored mainly due to shortage of accurate data. The effects of climate and soil on forest growth may vary due to local adaptation to both climate and soil, and these local adaptations might need to be considered when transferring seed provenances under climate change. Data from 29 provenance trials of Norway spruce (Picea abies (L.

Varying selection differential throughout the climatic range of Norway spruce in Central Europe.

Predicting species distribution changes in global warming requires an understanding of how climatic constraints shape the genetic variation of adaptive traits and force local adaptations. To understand the genetic capacity of Norway spruce populations in Central Europe, we analyzed the variation in tree heights at the juvenile stage in common garden experiments established from the species' warm-dry to cold-moist distribution limits. We report the following findings: First, 47% of the total tree height variation at trial sites is attributable to the tree populations irrespective of site climate.

Effect of chronic kidney disease on macrophage cholesterol efflux.

Aims: Patients with chronic kidney disease (CKD) have a high risk to develop atherosclerosis. The capacity of high-density lipoproteins (HDL) or serum to accept cholesterol from macrophages and the capacity of macrophages to export excess cholesterol are critical for the atheroprotective role of reverse cholesterol transport. HDL cholesterol acceptor capacity was reported to be decreased in middle aged hemodialysis patients, but the role of confounding factors remains unclear.
