Climate effects and human impacts, that is, nutrient enrichment, simultaneously drive spatial biodiversity patterns. However, there is little consensus about their independent effects on biodiversity. Here we manipulate nutrient enrichment in aquatic microcosms in subtropical and subarctic regions (China and Norway, respectively) to show clear segregation of bacterial species along temperature ...

The purpose of this study is to investigate horizontal transport processes in the winter stratosphere using data with a resolution relevant for chemistry and climate modeling. For this reason the Freie Universität Berlin Climate Middle Atmosphere Model (FUB-CMAM) with its model top at 83 km altitude, increased horizontal resolution T42 and the semi-Lagrangian transport scheme for advecting pass...

A climate model that includes a coupled ocean biogeochemistry model is used to define large oceanic biomes in the North Pacific Ocean and describe their changes over the 21st century in response to the IPCC Special Report on Emission Scenario A2 future atmospheric CO2 emissions scenario. Driven by enhanced stratification and a northward shift in the mid-latitude westerlies under climate change,...

Olive (Olea europaea L.) consumption and production are socially and economically important in Iran. The aim of this experiment was to evaluate the vegetative characteristics, floral biology, fruit characteristics, oil percentage, and yield of eleven olive cvs. (‘Arbequina’, ‘Amygdalolia’, ‘Bledy’, ‘Roghani’, ‘Zard’, ‘Sevillana’, ‘Koroneiki’, ‘Conservalia’, ‘Gordal Sevillana’, ‘Manzanilla’, and...

From a simple and a global coupled model, we showed that the tropical and extratropical oceanatmosphere interactions and the teleconnection between the tropics and extratropics in these interactions are responsible for the co-variations of the decadal to interdecadal climate fluctuations in the tropical and extratropical Pacific. The subtropical oceanic Rossby waves are found to play an importa...

Subtropical forests are important carbon sinks and have a huge potential for mitigating climate change. However, few studies have developed biomass models to give robust estimates of subtropical forest aboveground and belowground biomass. Although wood density (WD) can greatly reduce the uncertainty in aboveground biomass (AGB) estimates in tropical forest, it has never been applied in other ec...

We present an assessment of the impact of future climate change on two key drivers of fire risk in Australia, fire weather and fuel load. Fire weather conditions are represented by the McArthur Forest Fire Danger Index (FFDI), calculated from a 12-member regional climate model ensemble. Fuel load is predicted from net primary production, simulated using a land surface model forced by the same r...

BACKGROUND Climate and sunlight (ultraviolet radiation) influence activity of atopic eczema. OBJECTIVE To evaluate the effect of moving from a subarctic/temperate climate to a sunny subtropical climate on children's atopic eczema. METHODS Children, 4-13 years, with severe atopic eczema were randomized to stay 4 weeks in Gran Canary (index patients = 30) and home in Norway (controls = 26), w...

[1] The Southern Hemisphere subtropical anticyclones (SAs) are important features of the Earth’s climate. A broad consensus among Coupled Model Intercomparison Project phase 3 and phase 5 climate models suggests an intensification of summer SAs over SH oceans in association with the increase in greenhouse gas concentrations in the atmosphere. Diagnostic and modeling analyses conducted here demo...
