Renewable energy is a promising alternative to fossil fuel-based energy, but its
development can require a complex set of environmental tradeoffs. A recent increase in …

Sažetak The global energy demand is growing substantially. Clean and secure energy
supply is a must for our civilization's sustainable development. Solar and wind energy is …

Atmospheric nitrogen (N) deposition is a recognized threat to plant diversity in temperate
and northern parts of Europe and North America. This paper assesses evidence from field …

Human activity in the last century has led to a significant increase in nitrogen (N) emissions
and atmospheric deposition. This N deposition has reached a level that has caused or is …

Arid ecosystems cover∼ 40% of the Earth's terrestrial surface and store a high proportion of
the global nitrogen (N) pool. They are low-productivity, low-biomass, and polyextreme …

Empirical critical loads for N deposition effects and maps showing areas projected to be in
exceedance of the critical load (CL) are given for seven major vegetation types in California …

Plant invasions can affect fuel characteristics, fire behavior, and fire regimes resulting in
invasive plant-fire cycles and alternative, self-perpetuating states that can be difficult, if not …

Increased available soil nitrogen can increase biomass, lower species richness, alter soil
chemistry and modify community structure in herbaceous ecosystems worldwide. Although …

Biodiversity has been described as the diversity of life on earth within species, among
species, and among ecosystems. The rate of biodiversity loss due to human activity in the …

Primary production in deserts is limited by soil moisture and N availability, and thus is likely
to be influenced by both anthropogenic N deposition and precipitation regimes altered as a …
