There are several geographic features that separate two ecozones. These may be the alps, oceans, deserts, or even seas.
The main feature that separates the Nearctic and Neotropical ecozones in the Western Hemisphere is the presence of the Isthmus of Panama. This land bridge connects North and South America, allowing for some species to migrate between the two ecozones while others remain isolated.
A mountain range often separates two ecozones as it can create different climate conditions and habitats on either side, leading to distinct ecological zones.
The Lombok Strait
The Isthmus of Panama
The Andes mountain range separates the Neotropical ecozone to the east and the Nearctic ecozone to the west in the western hemisphere. The Andes act as a significant barrier, influencing climate and species distribution in these two distinct ecozones.

The Sahara Desert.
There are several geographic features that separate two ecozones. These may be the alps, oceans, deserts, or even seas.
Mountains are the most dominant feature that separates azerbaijan from turkmenistan.
Palearctic and Afrotropic.
Two major ecozones that cover the western hemisphere are the Nearctic ecozone, which includes North America, and the Neotropical ecozone, which covers Central and South America. These ecozones contain diverse habitats and species due to the varied climate and geography found in the western hemisphere.
