Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden

open access: yesNordic Journal of Botany, EarlyView.
To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

Post fire seedling and resprout survival of Melasma laurina

open access: yes, 2019
For this research project we set out to see how seedling and resprout survival rate of melasma laurina would fare in the post fire environment found around pepperdine. The expected seedling survival was set to be 1% and the resprout survival was at 100%.

The hunt for Scabiosa trenta Hacq: how the pursuit of a phantom ignited a passion for botany and mountaineering

open access: yesNordic Journal of Botany, EarlyView.
Scabiosa trenta Hacq. was first described in 1782 by Balthasar Hacquet, with its specific epithet referring to the Trenta Valley in Slovenia. Since then, S. trenta has been the focus of numerous mountaineering and botanical expeditions, particularly by the alpinist Julius Kugy during the Golden Age of Alpinism, a period in the second half of 19th ...

The dominance of non‐native plants over native plants increases with the number of global change factors

open access: yesOikos, EarlyView.
Global environmental change and plant invasion are both recognized as key indicators of the Anthropocene. Still, how the number of co‐acting global change factors (GCFs) influence invaded plant communities remains unclear, even though in nature GCFs usually act together rather than alone.

ASSESSMENT OF WHITEBARK PINE SEEDLING SURVIVAL FOR ROCKY MOUNTAIN PLANTINGS

open access: yes, 2007
Whitebark pine (WBP) is a keystone species of Rocky Mountain alpine and subalpine areas. A pervasive non-native fungal disease (white pine blister rust), mountain pine beetle infestation, and successional replacement by shade-tolerant competitors ...

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

open access: yesOikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Severity, Logging and Microsite Influence Post-Fire Regeneration of Maritime Pine

open access: yesFire
We investigated the influence of fire severity, logging of burnt wood, local ecological factors and their interaction on the natural regeneration, survival and growth of maritime pine (Pinus pinaster Ait.), following a fire that took place in 2005 ...
