TLDR
This book builds a mechanistic, resource-based explanation of the structure and functioning of ecological communities and explores such problems as the evolution of "super species," the differences between plant and animal community diversity patterns, and the cause of plant succession.
The metacommunity concept: a framework for multi-scale community ecology
TLDR
This framework is used to discuss why the metacommunity concept is useful in modifying existing ecological thinking and illustrate this with a number of both theoretical and empirical examples.
HUMAN ALTERATION OF THE GLOBAL NITROGEN CYCLE: SOURCES AND CONSEQUENCES
Nitrogen is a key element controlling the species composition, diversity, dynamics, and functioning of many terrestrial, freshwater, and marine ecosystems. Many of the original plant species living
Agricultural sustainability and intensive production practices
A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they
Biodiversity loss and its impact on humanity
TLDR
It is argued that human actions are dismantling the Earth’s ecosystems, eliminating genes, species and biological traits at an alarming rate, and the question of how such loss of biological diversity will alter the functioning of ecosystems and their ability to provide society with the goods and services needed to prosper is asked.
Solutions for a cultivated planet
TLDR
It is shown that tremendous progress could be made by halting agricultural expansion, closing ‘yield gaps’ on underperforming lands, increasing cropping efficiency, shifting diets and reducing waste, which could double food production while greatly reducing the environmental impacts of agriculture.
Global food demand and the sustainable intensification of agriculture
TLDR
Per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960 and forecasts a 100–110% increase in global crop demand from 2005 to 2050.
Land Clearing and the Biofuel Carbon Debt
TLDR
Converting rainforests, peatlands, savannas, or grasslands to produce food crop–based biofuels in Brazil, Southeast Asia, and the United States creates a “biofuel carbon debt” by releasing 17 to 420 times more CO2 than the annual greenhouse gas reductions that these biofuel reductions would provide by displacing fossil fuels.
Competition and Biodiversity in Spatially Structured Habitats
TLDR
The spatial competition hypothesis seems to explain the coexistence of the numerous plant species that compete for a single limiting resource in the grasslands of Cedar Creek Natural History Area and provides a testable, alternative explanation for other high diversity communities, such as tropical forests.
Biodiversity and Ecosystem Functioning: Current Knowledge and Future Challenges
TLDR
Larger numbers of species are probably needed to reduce temporal variability in ecosystem processes in changing environments and to determine how biodiversity dynamics, ecosystem processes, and abiotic factors interact.
