Habitat fragmentation and its lasting impact on Earth’s ecosystems
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.

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.
Primary forests are irreplaceable for sustaining tropical biodiversity
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.
Drought Sensitivity of the Amazon Rainforest
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.
The fate of Amazonian forest fragments: A 32-year investigation
RAIN FOREST FRAGMENTATION AND THE DYNAMICS OF AMAZONIAN TREE COMMUNITIES
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.

The results presented here suggest that the total biomass of these plots has on average increased and that there has been a regional-scale carbon sink in old-growth Amazonian forests during the previous two decades.
