Data from: The use of cattle Bos taurus for restoring and maintaining holarctic landscapes: conclusions from a long-term study (1946-2017) in northern England

Stephen J. G. Hall & Robert G. H. Bunce
Cattle Bos taurus can perform valuable ecological functions in the maintenance of high nature value (HNV) pastoral systems. They have also attracted attention as potentially filling the ecological niches of megaherbivores, notably the extinct aurochs Bos primigenius, in rewilding initiatives. Native cattle breeds are recognized under the 1992 Rio Convention as components of biodiversity. They are used in HNV settings, but their conservation as breeds has rarely been an important consideration for their management in...

1. Sedimentary pollen offers excellent opportunities to reconstruct vegetation changes over past millennia. Number of different pollen taxa or pollen richness is used to characterise past plant richness. To improve the interpretation of sedimentary pollen richness, it is essential to understand the relationship between pollen and plant richness in contemporary landscapes. This study presents a regional-scale comparison of pollen and plant richness from northern Europe and evaluates the importance of environmental variables on pollen and...

Data from: Canopy leaf area index at its higher end: dissection of structural controls from leaf to canopy scales in bryophytes

Ülo Niinemets & Mari Tobias
There is evidence that mosses with miniature foliage elements have extremely large leaf area indices (LAI), but it is unclear what canopy traits are responsible for these high LAI values in architecturally divergent mosses, and how the inherent tradeoffs limiting maximum LAI in vascular plants can be overcome in mosses. To determine the quantitative significance of different traits in determining LAI, we developed a method to dissect LAI into underlying functionally dependent constituent traits at...

Catchment properties and the photosynthetic trait composition of freshwater plant communities

Lars Lønsmann Iversen, A. Winkel, L. Baastrup-Spohr, A. B. Hinke, J. Alahuhta, A. Baattrup-Pedersen, S. Birk, P. Brodersen, P. A. Chambers, F. Ecke, T. Feldmann, D. Gebler, J. Heino, T. S. Jespersen, S. J. Moe, T. Riis, L. Sass, O. Vestergaard, S. C. Maberly, K. Sand-Jensen & O. Pedersen
Unlike in land plants, photosynthesis in many aquatic plants relies on bicarbonate in addition to carbon dioxide (CO2) to compensate for the low diffusivity and potential depletion of CO2 in water. Concentrations of bicarbonate and CO2 vary greatly with catchment geology. In this study, we investigate whether there is a link between these concentrations and the frequency of freshwater plants possessing the bicarbonate use trait. We show, globally, that the frequency of plant species with...
