Titanium dioxide nanoparticles (TiO(2)NPs) generally have positive effects on growth and physiological parameters in plants, but their impacts on photosynthesis and antioxidant system are poorly understood. This work aimed to assess the effects of TiO(2)NPs on photosynthetic performance and antio...

The objective was to evaluate water-soluble carbohydrate (WSC) and crude protein (CP) concentration of perennial ryegrass (PRG) cultivars with different genetic potential for producing WSC under two contrasting agronomic managements in temperate climate (southern Chile). A 4 x 2 factorial design ...

Agricultural land covers approximately 40% of Earth's land surface and affects hydromorphological, biogeochemical and ecological characteristics of fluvial networks. In the northern temperate region, agriculture also strongly affects the amount and molecular composition of dissolved organic matte...

We analyzed C band and L band interferometric synthetic aperture radar (InSAR) data acquired from 2003 to 2011 to search for volcanic deformations at Llaima volcano, Southern Andes (38.69 degrees S, 71.73 degrees W). There, specific environmental conditions (steep slopes, snow- or ice-capped summ...

Antarctic and Subantarctic lakes are unique ecosystems with relatively simple food webs, which are likely to be strongly affected by climate warming. While Antarctic freshwater invertebrates are adapted to extreme environmental conditions, little is known about the factors determining their curre...

Earth is heading towards a climate that last existed more than three million years ago (Ma) during the 'mid-Pliocene warm period'(1), when atmospheric carbon dioxide concentrations were about 400 parts per million, global sea level oscillated in response to orbital forcing(2,3) and peak global-me...

Climate change and infectious disease by the chytrid fungus Batrachochytrium dendrobatidis (Bd) are major drivers of amphibian extinctions, but the potential interactions of these two factors are not fully understood. Temperature is known to influence (1) the infectivity, pathogenicity and virule...
