Summary
Global warming disrupts ecosystem functions, impacting energy transfer and nutrient cycling. Maintaining species diversity is crucial for ecosystem resilience and essential services.
Area of Science:
- Ecology and Environmental Science
- Climate Change Biology
- Ecosystem Function and Services
Background:
- Ecosystem functions, including energy transfer and nutrient cycling (carbon, oxygen, nitrogen), are fundamental to planetary health.
- Global warming is altering these critical processes and the interactions between organisms.
- Ecosystem services, vital for human society, are threatened by these changes.
Purpose of the Study:
- To review the mechanisms of ecosystem functions and their alteration by global warming.
- To analyze the impacts of rising temperatures on species interactions and ecosystem services.
- To provide guidelines for research quantifying the link between ecosystem function and global warming.
Main Methods:
- Review of scientific literature on ecosystem functions, energy transfer, and nutrient cycling.
- Analysis of case studies demonstrating the effects of global warming.
- Development of research guidelines focusing on species diversity, functional groups, and resilience.
Main Results:
- Increased temperatures negatively affect interactions between autotrophs and heterotrophs, impacting ecosystem services.
- Heightened species co-extinction rates are a potential consequence of warming.
- Species diversity acts as a critical buffer for ecosystem services against warming impacts.
Conclusions:
- Maintaining species diversity is essential for ecosystem resilience and the continued provision of ecosystem services.
- Long-term monitoring and targeted research are necessary to understand and mitigate warming impacts.
- Adaptive conservation strategies informed by localized research are key to long-term planning.

01:50Global 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.
01:27Microbes 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...
01:50Threats 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...
01:16What 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.
02:26Ecological Disturbance
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.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...
01:39Keystone Species
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a pivotal role in the...
