Threats to Biodiversity

22.9K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Ecological Disturbance

17.5K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Summary
This summary is machine-generated.

Fragmented forest landscapes with smaller, dispersed conifer patches increase spruce budworm (SBW) infestation risk. Landscape configuration metrics, like patch size and shape, are key drivers of SBW outbreaks, informing forest management strategies.

Area of Science:

  • Forestry
  • Ecology
  • Remote Sensing

Background:

  • Spruce budworm (SBW) is a major forest defoliator in North America.
  • SBW impacts are linked to host species availability and landscape configuration.
  • Long-distance dispersal of SBW suggests landscape structure influences infestation success.

Purpose of the Study:

  • To test the hypothesis that fragmented landscapes promote SBW infestations.
  • To investigate the role of landscape configuration in modulating SBW defoliation.
  • To identify drivers of SBW infestation probabilities and their evolution.

Main Methods:

  • Utilized Landsat imagery and Forest Resource Inventory data over 13 years in eastern Quebec.
  • Extracted landscape configuration metrics (area, aggregation, shape) for conifer patches.
  • Employed random forest models to estimate infestation probabilities based on configuration metrics.

Main Results:

  • Higher fragmentation of conifer patches correlated with increased SBW infestation risk.
  • Key indicators of high risk include small, variable patch sizes (<40 ha), low landscape patch index (<50%), high cohesion (>97%), and complex shapes.
  • The landscape patch index significantly influenced SBW infestation.

Conclusions:

  • Freely available Landsat data can effectively extract configuration metrics for spatial analysis.
  • Probability estimates from models highlight high-risk landscape configurations.
  • Findings inform forest management for reducing conifer stand fragmentation and infestation risk.
