In ecology, biotic and abiotic factors encompass all the living and non-living parts of an ecosystem. Biotic factors pertain to living organisms and their relationships. Abiotic factors are the ...

Since Charles Darwin, biologists have been using the so-called "biotic interactions" hypothesis to explain, at least in part, why the tropics around the equator are so species rich. The hypothesis ...

Ecosystem is a system or phenomenon of interaction between abiotic and biotic factors in a certain area of the biosphere. The biosphere may be divided into smaller ecological units each of which ...

Surprisingly, we found that biotic, or living, interactions are crucial in shaping biodiversity patterns even in the extreme ecosystems of the Antarctic Dry Valleys.' Antarctica is a nearly ...

Members of the public are invited to join area naturalists and their colleagues for the 2014 "BioBlitz" that will focus on biotic interactions, such as the critically important role of pollinating ...

Main conclusions: Our study, spanning an entire continental-scale biota, helps to establish a generalized relationship among life-history traits and rarity in lichens and highlights the significance ...

Predicting the location of such ecological refuges is challenging, because they are shaped by the habitat requirements of native and invasive species, their biotic interactions, and the spatial and ...

The competition for niches is shaped by species’ interactions with the environment, which includes both abiotic elements (climate, water, soil, and such) and biotic elements (in other words ...

“A fundamental question is uncovering the role of biotic interactions in shaping antibiotic susceptibility in microbiomes. In particular, understanding how microbial interactions alter the ...
