Background and aims Cover crops are an important measure for carbon (C) sequestration in agriculture. However, little is known about the potential of cover crops to increase C under Nordic conditions and the efficiency of this measure over time. Here, we quantify the potential contribution of different cover crops to soil organic carbon (SOC) and organic matter fractions, and study how this is affected by the origin of the C i...

The climatic fluctuations during glaciations have affected differently arctic and temperate species. In the northern hemisphere, cooling periods induced the expansion of many arctic species to the south, while temperate species were forced to retract in southern refugia. Consequently, in some areas the alternation of these species set the conditions for competition and eventually hybridization. Hares in the Iberian Peninsula a...

Hepatocytes were isolated and cultured from Hoplias malabaricus using a non‐enzymatic protocol. From 6·9 to 9·4 × 10 7 hepatocytes g −1 of liver were isolated and cell viability was 65–85%. Fish hepatocytes attached well to untreated polystyrene flasks (Corning) as well as on treated surfaces with extracellular matrix proteins, i.e. fibronectin, matrigel or type I collagen coatings. Cells rapidly started migrating and reorgani...

Methods recently developed to infer population structure and admixture mostly use individual genotypes described by unlinked neutral markers. However, Hardy–Weinberg and linkage disequilibria among independent markers decline rapidly with admixture time, and the admixture signals could be lost in a few generations. In this study, we aimed to describe genetic admixture in 182 European wild and domestic cats ( Felis silvestris )...

We used noninvasive methods to obtain genetic and demographic data on the wolf packs ( Canis lupus ), which are now recolonizing the Alps, a century after their eradication. DNA samples, extracted from presumed wolf scats collected in the western Italian Alps (Piemonte), were genotyped to determine species and sex by sequencing parts of the mitochondrial DNA (mtDNA) control‐region and ZFX/ZFY genes. Individual genotypes were i...
