Plant-animal interactions are important pathways for the transfer of energy within ecosystems, where both advantageous and unfavorable interactions support ecosystem health. [ 1 ] [ 2 ] Plant-animal interactions can take on important ecological functions and manifest in a variety of combinations of favorable and unfavorable associations, for ...
Ecosystem ecology is the integrated study of living and non-living components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals , bedrock , soil , plants , and animals .
On broad geographic scales, climate is the factor that "most strongly determines ecosystem processes and structure". [4]: 14 Climate determines the biome in which the ecosystem is embedded. Rainfall patterns and seasonal temperatures influence photosynthesis and thereby determine the amount of energy available to the ecosystem. [8]: 145
Overall, the effects of climate change increase stress on ecosystems, and species unable to cope with the rapidly changing conditions will go extinct. [28] While modern climate change is caused by humans, past climate change events occurred naturally and have led to extinctions.
Among aquatic and terrestrial ecosystems, patterns have been identified that can account for this variation and have been divided into two main pathways of control: top-down and bottom-up. [22] [23] The acting mechanisms within each pathway ultimately regulate community and trophic level structure within an ecosystem to varying degrees. [24]
One way of mapping terrestrial (land) biomes around the world. A biome (/ ˈ b aɪ. oʊ m /) is a distinct geographical region with specific climate, vegetation, and animal life.It consists of a biological community that has formed in response to its physical environment and regional climate.
Macroecology is a subfield in ecology that uses a methodological approach that investigates the empirical patterns and mechanistic processes by which the particulate components of complex ecological systems generate emergent structures and dynamics [1] Unlike traditional ecology, which focuses on local and small-scale interactions, macroecology seeks to identify general emergent patterns ...
This stream operating together with its environment can be thought of as forming a river ecosystem. River ecosystems are flowing waters that drain the landscape, and include the biotic (living) interactions amongst plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions of its many parts.
