Impacts of Climate Change on Ecosystems and Biodiversity in the United States

Climate change is significantly affecting species, populations, and ecosystems in the United States. Changes include alterations in the characteristics of organisms, shifts in biological event timing, and disruptions in geographic ranges. These impacts can lead to extinctions when species can't adap

Evolutionary Insights from the Ordovician Period

The Ordovician period was marked by significant events such as the average temperature and atmospheric CO2 levels, the emergence of diverse life forms, glacial events leading to mass extinctions, and the survival of the fittest in evolving environments. Primitive reefs, major evolutionary radiation

The Impact of Continental Drift on Earth's Biogeography

Continental drift, caused by the movement of tectonic plates, has had profound effects on Earth's habitats and the distribution of organisms. From the formation of supercontinents to the separation of land masses, these geological processes have led to climate change, speciation events, mass extinct
