An Economic Valuation of Pollination Services in Georgia
The production of many crops depends on biotic pollination. As pollinator populations decline, assessments of the potential consequential loss of economic value are critical.

Pollination ecology of the invasive tree tobacco Nicotiana glauca: comparisons across native and non-native ranges [PDF]
, 2012 Interactions with pollinators are thought to play a significant role in determining whether plant species become invasive, and ecologically generalised species are predicted to be more likely to invade than more specialised species.

Nordic Journal of Botany, EarlyView.A new species, Centaurea baghmalekensis Negaresh (Asteraceae) in C. sect. Microlophus (Cass.) DC., is described and illustrated from the Khuzestan Province, southwestern Iran. The new species is morphologically most similar to Centaurea pabotii Wagenitz, a recently described species from the Khuzestan Province.

Oikos, 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.

Both density‐ and frequency‐dependent effects determine plant growth in a dune heath ecosystem
Oikos, EarlyView.We tested the hypothesis that both density‐ and frequency‐dependent interactions play important roles in determining plant growth in a dune heath ecosystem at several levels of available nitrogen. Plant growth was measured using the pin‐point method in a five‐block experiment with four nitrogen levels.

Habitat loss reshuffles ecological and evolutionary interactions in a seed dispersal network
Oikos, EarlyView.In tropical forests, habitat loss reshapes species composition, favoring generalists and recently emerged lineages while specialists and older evolutionary lineages are lost. However, how changes in species ecological attributes and evolutionary history affect ecological processes is poorly explored.
