Ecosystem Decay of Amazonian Forest Fragments: a 22-Year Investigation
We synthesized key findings from the Biological Dynamics of Forest Fragments Project, the world's largest and longest-running experimental study of habitat fragmentation. Although initially designedExpand
Habitat fragmentation and its lasting impact on Earth’s ecosystems
TLDR
An analysis of global forest cover is conducted to reveal that 70% of remaining forest is within 1 km of the forest’s edge, subject to the degrading effects of fragmentation, indicating an urgent need for conservation and restoration measures to improve landscape connectivity. Expand
Landscape moderation of biodiversity patterns and processes ‐ eight hypotheses
TLDR
This review uses knowledge gained from human‐modified landscapes to suggest eight hypotheses, which it hopes will encourage more systematic research on the role of landscape composition and configuration in determining the structure of ecological communities, ecosystem functioning and services. Expand
Primary forests are irreplaceable for sustaining tropical biodiversity
TLDR
It is found that biodiversity values were substantially lower in degraded forests, but that this varied considerably by geographic region, taxonomic group, ecological metric and disturbance type. Expand
Variation in wood density determines spatial patterns in Amazonian forest biomass
Uncertainty in biomass estimates is one of the greatest limitations to models of carbon flux in tropical forests. Previous comparisons of field-based estimates of the aboveground biomass (AGB) ofExpand
The fate of Amazonian forest fragments: A 32-year investigation
Abstract We synthesize findings to date from the world’s largest and longest-running experimental study of habitat fragmentation, located in central Amazonia. Over the past 32 years, Amazonian forestExpand
Drought Sensitivity of the Amazon Rainforest
TLDR
Records from multiple long-term monitoring plots across Amazonia are used to assess forest responses to the intense 2005 drought, a possible analog of future events that may accelerate climate change through carbon losses and changed surface energy balances. Expand
RAIN FOREST FRAGMENTATION AND THE DYNAMICS OF AMAZONIAN TREE COMMUNITIES
TLDR
It is revealed that fragmentation causes important changes in the dynamics of Amazonian forests, especially within ∼100 m of habitat edges, and edge effects will increase rapidly in importance once fragments fall below ∼100–400 ha in area, depending on fragment shape. Expand
Theory meets reality: How habitat fragmentation research has transcended island biogeographic theory
TLDR
Fragmentation often has diverse impacts on ecosystem properties such as canopy-gap dynamics, carbon storage, and the trophic structure of communities that are not considered by IBT, and is highlighted with findings from fragmented ecosystems around the world. Expand
Predicting the impacts of edge effects in fragmented habitats
Abstract We propose a protocol for assessing the ecological impacts of edge effects in fragments of natural habitat surrounded by induced (artificial) edges. The protocol involves three steps: (1)Expand
