Question

What is an example of a physical barrier? how might it affect where species are found?

Answer 1

Actual hindrances to dispersal comprise scenes that keep creatures from migrating. Mountains, waterways, and lakes are instances of actual hindrances that can restrict an animal types' dispersion.

Complete answer:
Physical barriers contribute to habitat fragmentation, influence species distribution and ranging behavior, and have an impact on population viability in the long term. Barrier permeability varies between species and has the potential to affect the competitive balance within animal communities by affecting co-occurring species differently.

Despite this, little attention has been paid to the effect of barriers on the spatial distribution of species within entire communities. Over a four-year period, we investigated the impact of a fence and rivers, two landscape features that may act as barriers to lions' space use and ranging behavior. Panthera leo, as well as spotted hyenas Crocuta crocuta, also known as African wild dogs Cheetahs Acinonyx jubatus in Northern Botswana.

Time, Place, Space, Climate, and Noise are the major environmental / physical barriers. Some of them are simple to change, while others may prove to be difficult roadblocks in the process of effective communication.

The water barriers of different islands influence species migration from one island to the next. The species of specific islands are specialized in order to survive on those islands.
One example of a finch bird was reported by Charles Darwin. The birds' beaks were specialized based on the food available on the islands.

Note: Insurmountable physical barriers, such as mountains, oceans, rivers, deserts, and, more recently, expansive human development, are the most visible limitations to a species' geographic distribution. These barriers directly obstruct species dispersal, particularly in the cases of oceans for terrestrial species, land masses for marine species, and transitions between freshwater and marine systems for many aquatic organisms. Some species are also hampered by physical barriers that emerge on a regular basis, such as in areas prone to flooding, fires, or volcanic eruptions.
