BUTTERFLIES AND PLANTS: A STUDY IN COEVOLUTION
TLDR
The relationship between butterflies and their food plants is investigated, the examination of patterns of interaction between two major groups of organisms with a close and evident ecological relationship, such as plants and herbivores. Expand
IMPACT OF POPULATION GROWTH
TLDR
The study concludes that population growth should be controlled to keep pace with agricultural development so that the two districts can achieve economic development. Expand
HUMAN APPROPRIATION OF THE PRODUCTS OF PHOTOSYNTHESIS
TLDR
The figures reflect the current patterns of exploitation distribution and consumption of a much larger population; there must be limits to growth. Expand
Accelerated modern human–induced species losses: Entering the sixth mass extinction
TLDR
Estimates of extinction rates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way and a window of opportunity is rapidly closing. Expand
Human Appropriation of Renewable Fresh Water
Humanity now uses 26 percent of total terrestrial evapotranspiration and 54 percent of runoff that is geographically and temporally accessible. Increased use of evapotranspiration will confer minimalExpand
Economic value of tropical forest to coffee production.
TLDR
The value of tropical forest in supplying pollination services to agriculture translates into approximately 60,000 USD per year for one Costa Rican farm during 2000-2003, which is commensurate with expected revenues from competing land uses and far exceeds current conservation incentive payments. Expand
Are We Consuming Too Much?
This paper articulates and applies frameworks for examining whether consumption is excessive. We consider two criteria for the possible excessiveness (or insufficiency) of current consumption. One isExpand
Should agricultural policies encourage land sparing or wildlife‐friendly farming?
As the demands on agricultural lands to produce food, fuel, and fiber continue to expand, effective strategies are urgently needed to balance biodiversity conservation and agricultural production.Expand
ECOSYSTEM SERVICES: Benefits Supplied to Human Societies by Natural Ecosystems
Human societies derive many essential goods from natural ecosystems, including seafood, game animals, fodder, fuelwood, timber, and pharmaceutical products. These goods represent important andExpand
