Grand Mesa Study Plot
Cleaned (quality checked) and continuous hourly records of snow energy and mass balance variables from Grand Mesa Study Plot (GMSP). GMSP is located in an opening in a pine forest on the northern rim of the Grand Mesa (39.050802, -108.061435) in west central Colorado at 3239 m. The site was funded b

Data from: How persistent are the impacts of logging roads on Central African forest vegetation?
1. Logging roads can trigger tropical forest degradation by reducing the integrity of the ecosystem and providing access for encroachment. Therefore, road-management is crucial in reconciling selective logging and biodiversity conservation. Most logging roads are abandoned after timber harvesting, h
Data from: Growth and carbon relations of mature Picea abies trees under 5 years of free-air CO2 enrichment
Are mature forests carbon limited? To explore this question, we exposed ca. 110-year-old, 40-m tall Picea abies trees to a 550-ppm CO2 concentration in a mixed lowland forest in NW Switzerland. The site receives substantial soluble nitrogen (N) via atmospheric deposition, and thus, trees are unlikel
Data from: The mechanical defence advantage of small seeds
Seed size and toughness affect seed predators, and size-dependent investment in mechanical defence could affect relationships between seed size and predation. We tested how seed toughness and mechanical defence traits (tissue density and protective tissue content) are related to seed size among trop
Data from: Observed forest sensitivity to climate implies large changes in 21st century North American forest growth
Predicting long-term trends in forest growth requires accurate characterisation of how the relationship between forest productivity and climatic stress varies across climatic regimes. Using a network of over two million tree-ring observations spanning North America and a space-for-time substitution
Geographic variation in vocalizations and evolution of North American pine grosbeaks
North American Pine Grosbeaks (Pinicola enucleator) vary geographically in two of their call notes. Variation is greatest in the location calls that communicate between individuals at great distances. Birds of the taiga and coastal Alaska give whistled calls, of which four categories have been ident
