Carbon‐focused climate mitigation strategies are becoming increasingly important in forests. However, with ongoing biodiversity declines we require better knowledge of how much such strategies account for biodiversity. We particularly lack information across multiple trophic levels and on established forests, where the interplay between carbon stocks, stand age, and tree diversity might influence carbon–biodiversity relationsh...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
Janzen‐Connell effects in a forest BEF experiment: Strong distance‐dependent seedling establishment of multiple speciesNARA Subscribed
The Janzen‐Connell (JC) hypothesis is a major ecological explanation for high species richness, in particular in tropical forest ecosystems. Central components of the JC hypothesis are noncompetitive effects of distance and density dependence, two drivers that contribute independently to species coexistence, but are ultimately linked in the field. However, although numerous studies provide evidence for either distance‐ or dens...
Exotic plant species are locally adapted but not to high ultraviolet‐B radiation: a reciprocal multispecies experimentNARA Subscribed
Ultraviolet ( UV ) radiation intensities differ among global regions, with significantly higher levels in the southern hemisphere. UV ‐B may act as an environmental filter during plant invasions, which might particularly apply to plant species from Europe introduced to New Zealand. Just like for any other abiotic or biotic filter, successful invaders can cope with novel environmental conditions via plastic responses and/or thr...
A comparison of native and invasive populations of three clonal plant species in Germany and New ZealandNARA Subscribed
Aim Our aim was to test for changes in growth patterns of three clonally growing plant species ( Achillea millefolium , Hieracium pilosella and Hypericum perforatum ) between native and invaded regions. We addressed the hypotheses that with differing important life‐history traits, invasive populations perform better than native populations, and that this expected better performance is linked to weakened trade‐offs between indi...
