Traits of the Leaf Economics Spectrum Do Not Always Relate to Species Biomass Proportions in Grassland Communities of Varying Diversity

Ecology and Evolution
Traits of the “leaf economics spectrum” (LES) relate to a functional trade‐off between slow and fast return on carbon investment, but it is not clear whether the globally observed trait‐relationships also hold in local plant communities.

Influence of summer transhumance practice in the Carpathians, Apuseni Mountains, Romania, on cattle milk production and quality

Frontiers in Animal Science
In the Apuseni Mountains, a particular type of short-distance transhumance has been practiced for hundreds of years, in which people move a proportion of their cattle to grassland at higher altitudes, allowing them to save the hay from the grassland ...

Taxon‐dependent multisite species turnover in fragmented habitats: comparing zeta diversity across birds, butterflies, and cursorial hunting spiders

Ecography, EarlyView.
Habitat fragmentation alters species diversity and reshapes community composition. However, conventional pairwise approaches to compositional variation (i.e. beta diversity metrics) do not explicitly characterize how species sharing or turnover change with the number of habitat patches.

Butterfly abundances but not patch occupancy buffered by vegetation heterogeneity during climatic extremes

Ecography, EarlyView.
As extreme climatic events are becoming more frequent, we need to understand what mechanisms could buffer populations to ensure their persistence. Fragmented populations may be especially vulnerable, as exemplified by species with metapopulation dynamics whose persistence is determined by a precarious balance between frequent local extinctions and ...

Thermal niche breadth shapes regional elevational range sizes of tropical‐like mountain stream insects: evidence for Janzen's tropical mountain passes hypothesis

Ecography, EarlyView.
The core of Janzen's tropical mountain passes hypothesis is that relatively stable annual temperature variation limits species' thermal tolerances breadth, which, in combination with steep elevational temperature gradients, constrains the elevational distributions of these species. In addition to thermal niche breadth, elevational ranges were shaped by

Grassland term definitions and classifications adapted to the diversity of European grassland-based systems

, 2014
Grasslands are represented in an unsatisfactory manner in agricultural statistics. The official definition of grasslands does not include vast areas of grazed shrubby and wooded ecosystems.

Nested Carbon Governance in Southeast Asia: Towards Just Nature‐Based Solutions?

Environmental Policy and Governance, EarlyView.
ABSTRACT Nature‐based solutions (NbS) have gained prominence as an integrated approach to addressing climate change and biodiversity loss while supporting sustainable development. Yet, their implementation across Southeast Asia remains fragmented and often contested.

Governing Agriculture or Farmers? Problem Representations of Biodiversity and Farm Loss in Swedens Strategy for the Common Agricultural Policy

Environmental Policy and Governance, EarlyView.
ABSTRACT European Union (EU) strategies for food supply address challenges of increasing, or at least maintaining, today's level of agricultural food production. At the same time, European farmland biodiversity continues to deteriorate despite considerable investments in measures to promote environmentally friendly farming practices.
