Resumen
La biodiversidad de las islas está determinada por los cambios climáticos del pasado. Las islas más grandes durante el Último Máximo Glacial (LGM) tienen más especies endémicas hoy en día, destacando el impacto de los cambios ambientales en la evolución de las especies.
Área de la Ciencia:
- Ecología
- Biogeografía
- Biología evolutiva
Sus antecedentes:
- Los modelos de biogeografía insular tradicionalmente ven las islas como entidades geológicas estáticas o que cambian lentamente.
- Estos modelos a menudo pasan por alto el profundo impacto de las oscilaciones climáticas rápidas y a corto plazo, como los ciclos glaciales, en los ecosistemas de las islas.
- Las fluctuaciones climáticas del Cuaternario tardío alteraron significativamente el área de la isla, el aislamiento y la conectividad, dinámicas que no fueron completamente capturadas por las teorías existentes.

01:50Global Climate Change
29.6K
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
15
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
27.8K
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?
21.3K
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.

01:30Marine Microbial Ecology
14
Marine microbial ecosystems are shaped by distinct physicochemical limits, including high salinity, low nutrient availability, and fluctuating oxygen levels. These conditions favor smaller microbial cell sizes, which maximize their surface-to-volume ratio for efficient nutrient uptake.Microbial activity and community composition are closely linked to biogeochemical cycles, particularly in dynamic environments like estuaries, where halotolerant microbes thrive in response to variable salinity...

02:31Habitat Fragmentation
21.8K
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.
