Study Notes
Biodiversity and Ecosystems
- Biodiversity is usually greater in tropical regions near the equator due to warm temperatures and abundant rainfall.
- Tropical rainforests cover less than 10% of Earth's surface but harbor approximately 90% of the world's species, showcasing their richness in biodiversity.
Marine Biodiversity
- Marine biodiversity is generally higher in coral reef ecosystems, which are often referred to as the "rainforests of the sea" for their diversity and productivity.
Threats to Biodiversity
- A primary reason for the likely slowing of biodiversity in the future is habitat loss, driven by human activities like deforestation, urbanization, and pollution.
Biodiversity Processes
- Biodiversity encompasses various processes including evolution, species interactions, ecological systems, and genetic variation within species.
Conservation Biology Focus
- The focus of conservation biology is to understand and protect biodiversity from threats like habitat degradation, climate change, and invasive species.
Origin of Conservation Biology
- The term 'conservation biology' originated in the 1980s as a response to increasing awareness of biodiversity loss and the need for scientific research to inform conservation efforts.
Interdisciplinary Nature
- The interdisciplinary nature of conservation biology is based on integrating knowledge from ecology, genetics, sociology, economics, and policy-making to address conservation issues comprehensively.
First International Conference on Conservation Biology
- 'The First International Conference on Research in Conservation Biology’ was convened by Michael Soule, a prominent figure in the field, to foster discourse and collaboration among scientists.
Motivation for the Conference
- The conference was prompted by the urgent need to address the rapid loss of biodiversity and to develop strategies for conservation and sustainable use of natural resources.
