Global Change and the Ecology of Cities
Urban areas are hot spots that drive environmental change at multiple scales. Material demands of production and human consumption alter land use and cover, biodiversity, and hydrosystems locally toExpand

Integrated approaches to long-term studies of urban ecological systems
This quote captures the spirit of the new urban emphasis in the US Long-Term Ecological Research (LTER) network. We know now that Earth abounds with both subtle and pronounced evidence of theExpand

Biogeochemical Hot Spots and Hot Moments at the Interface of Terrestrial and Aquatic Ecosystems
Rates and reactions of biogeochemical processes vary in space and time to produce both hot spots and hot moments of elemental cycling. We define biogeochemical hot spots as patches that showExpand

Socioeconomics drive urban plant diversity
Spatial variation in plant diversity has been attributed to heterogeneity in resource availability for many ecosystems. However, urbanization has resulted in entire landscapes that are now occupiedExpand

Inter‐biome comparison of factors controlling stream metabolism
SUMMARY 1. We studied whole-ecosystem metabolism in eight streams from several biomes in North America to identify controls on the rate of stream metabolism over a large geographic range. The streamsExpand

Stream denitrification across biomes and its response to anthropogenic nitrate loading
Anthropogenic addition of bioavailable nitrogen to the biosphere is increasing and terrestrial ecosystems are becoming increasingly nitrogen-saturated, causing more bioavailable nitrogen to enterExpand

Towards an ecological understanding of biological nitrogen fixation
N limitation to primary production and other ecosystem processes is widespread. To understand the causes and distribution of N limitation, we must understand the controls of biological N fixation.Expand

Nitrous oxide emission from denitrification in stream and river networks
Nitrous oxide (N2O) is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. Anthropogenic nitrogen (N) loading to river networks is a potentially importantExpand

TEMPORAL SUCCESSION IN A DESERT STREAM ECOSYSTEM FOLLOWING FLASH FLOODING
Recovery of a desert stream after an intense flash flooding event is described as a model of temporal succession in lotic ecosystems. A late summer flood in Sycamore Creek, Arizona, virtuallyExpand

The changing landscape : ecosystem responses to urbanization and pollution across climatic and societal gradients
Urbanization, an important driver of climate change and pollution, alters both biotic and abiotic ecosystem properties within, surrounding, and even at great distances from urban areas. As a result,Expand
