Ecología y Biodiversidad

Study Notes

Ecología

Ecology is the study of the relationships between organisms and their environment.
It examines the interactions between organisms and their physical and biological surroundings.
Key concepts include energy flow, nutrient cycling, population dynamics, and community structure.
Ecosystems are dynamic systems composed of interacting biotic and abiotic components.
Biodiversity is a crucial aspect of ecology. Healthy ecosystems tend to support high biodiversity.
Ecological principles are fundamental to conservation efforts and environmental management.

Biodiversidad

Biodiversity encompasses the variety of life on Earth at all levels, from genes to ecosystems.
It includes genetic diversity, species diversity, and ecosystem diversity.
High biodiversity contributes to ecosystem stability and resilience.
Biodiversity is essential for ecosystem services (e.g., nutrient cycling, pollination).
Threats to biodiversity include habitat loss, pollution, overexploitation, invasive species, and climate change.
Conservation efforts focus on protecting and restoring habitats, mitigating threats, and promoting sustainable practices.
Species richness and evenness are important metrics used to quantify biodiversity.

Cambio Climático

Climate change refers to long-term shifts in temperatures and weather patterns.
These shifts may be natural, but since the 1800s human activities have been the main driver of climate change, primarily due to the burning of fossil fuels.
Greenhouse gases trap heat in the atmosphere, leading to a warming planet.
Impacts of climate change include rising sea levels, more frequent and intense heat waves, changes in precipitation patterns, and disruptions to ecosystems.
Climate change affects biodiversity by altering habitats, disrupting migration patterns, and increasing the risk of extinction for many species.
Mitigation involves reducing greenhouse gas emissions through renewable energy sources and energy efficiency.
Adaptation strategies focus on adjusting to the unavoidable impacts of climate change, such as developing drought-resistant crops or building seawalls.
Climate change is a global challenge that requires international cooperation and global action to address.
Understanding the interconnectedness of ecosystems and the effects of climate change are vital for effective conservation strategies.
The impacts of climate change are not uniform across the globe. Some regions experience more severe effects than others.
Evidence of climate change includes rising global temperatures, melting glaciers and ice sheets, and changes in precipitation patterns.
Feedback loops can exacerbate climate change, for example, melting ice can reduce the Earth's reflectivity, causing more warming.
Climate models play a critical role in projecting future climate scenarios and informing adaptation and mitigation strategies.
