Spatial genetic structure of Scots pine (Pinus sylvestris) in Germany- results from the 4th German National Forest Inventory

Abstract In the course of the 4th German National Forest Inventory about 5,000 samples of Scots pine have been collected all over Germany. Analysis of 21 mitochondrial SNP markers on the collected samples allowed the detection of a clear spatial genetic structure separating North...

Alpine forest genomics—advances in the research field and perspectives ahead

Abstract Key message Alpine or mountainous forest genomics research is rapidly moving from classic population genetic studies toward exploring population environmental adaptation to address climate vulnerabilities. For alpine conifers in particular, future progress in sustainable...

Anthropogenic compound inputs decouple particulate and mineral-associated carbon pools in soils of a tropical urban agroecosystem

Urban soils accumulate diverse anthropogenic compounds (hereafter ACs). Yet, AC accumulation and its influence on soil organic carbon (SOC) dynamics remain poorly constrained. Here, we investigate how urbanisation-derived ACs affect SOC pools and composition in 618 arable topsoil...

Endogenous and exogenous control of tree architectural and hydraulic traits of European beech growing in natural populations

Abstract Key message Genetic components explain a moderate, yet statistically significant proportion of the phenotypic variation in tree architecture and hydraulic traits of beech trees growing in naturally regenerated monospecific stands. Abstract Drought tolerance of European b...

Food Security Versus Environmental Health: The Nitrogen Dilemma

ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the inf...

Potential of temperate agroforestry systems to deliver ecosystem services: An evidence map

Abstract. Agroforestry systems are promoted as multifunctional land-use strategies, yet evidence of their benefits, especially in temperate regions, remains fragmented. This umbrella review maps 42 meta-analyses to quantify the effects of agroforestry on environmental, climate, a...

Legacy effects of subsoil compaction and earthworm biopores on soil hydrophysical properties and root density in a temperate silt loam soil

The short- and medium-term effects of agricultural soil compaction are well documented, but its long-term impacts and the role of biopores in subsoil recovery remain poorly understood. This study evaluated legacy effects of subsoil compaction on soil hydrophysical properties and...

Population Structure, Fecundity, and Reproductive Patterns of Erichsonella attenuata (Isopoda: Valvifera: Idoteidae) in Tamiahua Lagoon, Veracruz, Mexico

Erichsonella attenuata is a free-living marine isopod distributed across the Gulf of Mexico; however, quantitative information on its population structure and reproductive biology remains limited. We examined 2315 individuals collected in Tamiahua Lagoon, Veracruz, Mexico, to des...

Plant species richness is key for restoring grassland butterfly assemblages

Abstract Palaearctic grasslands are heavily threatened by land‐use changes that lead to degradation and habitat loss. Thus, successful grassland restoration for vegetation and wildlife is urgently needed. Butterflies, as sensitive indicators, could provide a holistic view of rest...

Electoral outcomes of party families across regional development types in Europe

Abstract. The interplay between regional disparities and electoral outcomes is central to understanding political dynamics in Europe. In debates on the “geography of discontent”, radical-right party support is often linked to so-called left-behind regions. This study broadens tha...
