We used comprehensive data on phylogenetics, migratory behavior, and past and future climate to test the climate‐migration associations in a large radiation of roughly 1300 suboscine passerine birds. We demonstrate that while longer‐distance migration is influenced overwhelmingly by seasonal fluctuations in temperature, tropical migrations have more ...

Comprehensive ecosystem model-data synthesis using multiple data sets at two temperate forest free-air CO2 enrichment experiments: Model performance at ambient CO2 concentration [PDF]
Free-air CO2 enrichment (FACE) experiments provide a remarkable wealth of data which can be used to evaluate and improve terrestrial ecosystem models (TEMs).

Role of Leaf Traits in Driving Genotypic Diversity‐Mediated Associational Effects in Silver Birch
We investigated two genotypes of silver birch (Betula pendula) growing in monocultures and genotype mixture plots to determine whether genotypic diversity causes leaf trait variation, and whether these changes are linked to herbivory. Genotypic diversity had a significant effect on herbivory, with one of the genotypes suffering more herbivory in 2 ...

Energy balance closure of a Pine ecosystem of the Indian Himalayan region shows that the drought caused by low soil moisture led to more of the available energy being directed toward sensible heat flux, thereby intensifying drought stress. ABSTRACT This study presents the energy balance dynamics of a mature Pine (Pinus roxburghii) ecosystem of the ...

Pruning after budburst to delay and spread grape maturity
Background and Aims The shift in phenological development is the most conspicuous biological effect of climate change in vineyards worldwide. Associated with the advancement in maturity there has been a compression of the harvest period that places significant pressure on vineyard and winery infrastructure.

Rethinking False Spring Risk [PDF]
Temperate plants are at risk of being exposed to late spring freezes. These freeze events - often called false springs - are one of the strongest factors determining temperate plants species range limits and can impose high ecological and economic damage.

Outbreak‐prone insects often undergo explosive population growth despite high natural mortality caused by predators, disease, host toxicity and inclement weather. Although contemporary forest pest management focuses on short‐term tree protection, there is increasing interest in developing strategies to directly suppress outbreaks.

Predicting the risk of frost occurrence after budburst of Norway spruce in Sweden. [PDF]
Temperature sums required for budburst in various Norway spruce ( (L.) H. Karst.) provenances were determined, and weather statistics were then used to predict the risk of potentially damaging frosts at 11 locations in Sweden. Frost risk was quantified as the probability of a frost occurring within 100 day-degrees (two weeks) after budburst.

This study investigated how climate change has affected carbon uptake in a subalpine spruce forest in Switzerland over 26 years. Air temperatures rose and soil moisture declined, while the amount of carbon the forest absorbed each year increased until 2012, then stabilized and decreased.
