Threats to Biodiversity

Threats to Biodiversity

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...

Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

What is Climate?

What is Climate?

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Microbes and Climate Change

Microbes and Climate Change

Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...

Summary

This summary is machine-generated.

Climate change causes species extinctions primarily through altered species interactions, like reduced food availability, not just heat tolerance limits. Further research is needed to understand these complex extinction drivers.

Area of Science:

Ecology
Climate Change Biology
Conservation Biology

Background:

Anthropogenic climate change is a projected major driver of species extinctions.
Understanding the specific proximate causes of these extinctions is critical for effective conservation.
Limited physiological tolerance to heat is often assumed to be the primary cause.

Purpose of the Study:

To systematically review the proximate causes of climate-change related extinctions.
To assess the empirical support for different extinction drivers.
To identify knowledge gaps in understanding climate-driven extinctions.

Main Methods:

Systematic review of case studies on climatic impacts relevant to extinctions.
Analysis of 136 identified case studies.
Focus on demonstrated local extinctions attributed to anthropogenic climate change.

Main Results:

Only seven case studies identified proximate causes of demonstrated local extinctions due to climate change.
No studies showed a direct link between local extinction and limited high-temperature tolerance.
Species interactions, particularly decreased food availability, were frequently implicated as proximate causes.

Conclusions:

Current knowledge of climate-change related extinction proximate causes is limited.
Species interactions play a significant role in population declines and extinctions linked to climate change.
Future research should focus on identifying proximate causes, especially those involving species interactions.
