Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Anisotropic community turn‐over at habitat edges informs on assembly drivers: simulation and empirical test on soil macrofauna

Oikos, EarlyView.
Biodiversity dynamics in heterogeneous landscapes is the result of a complex interplay between movement processes of organisms within and between habitat patches, and niche filtering processes due to spatially varying environmental conditions. Disentangling the relative influences of these different processes on community assembly and dynamics is a ...

Phenological characterization of Fagus sylvatica L. in Mediterranean populations of the Spanish Central Range with Landsat OLI/ETM+ and Sentinel-2A/B

Revista de Teledetección, 2020
The Spanish Central Range hosts some of the southernmost populations of Fagus sylvatica L. (European beech). Recent cartography indicates that these populations are expanding, going up-streams and gaining ground to oak forests of Quercus pyrenaica Willd.,

Dynamics of common wasps in New Zealand beech forests: a model with density dependence and weather [PDF]

Journal of Animal Ecology, 2002
Summary Nest densities of the common wasp ( Vespula vulgaris (L.)) were monitored at six sites for 13 years in the honeydew‐rich southern beech ( Nothofagus spp.) forests of New Zealand's South Island. Densities of wasp nests were among the highest in the world, up to 30 ha −1 , and at any one site varied ...
