- This pattern describes the changing structure and productivity of the predator-prey biomass pyramid, which represents the biomass of communities at different levels of the food chain.了解详细信息：This pattern describes the changing structure and productivity of the predator-prey biomass pyramid, which represents the biomass of communities at different levels of the food chain.www.science.org/doi/10.1126/science.aac6284Predator–prey interactions in natural ecosystems generate complex food webs that have a simple universal body-size architecture where predators are systematically larger than their prey.www.nature.com/articles/s41559-019-0899-x
The predator-prey power law: Biomass scaling across ... - Science
2015年9月4日 · We show a robust scaling law that emerges uniquely at the level of whole ecosystems and is conserved across terrestrial and aquatic biomes worldwide. This pattern …

Consistent predator-prey biomass scaling in complex food webs
2022年8月25日 · We find a consistent, sub-linear scaling pattern whereby predator biomass scales with the total biomass of their prey with a near ¾-power exponent within food webs - …
between predator and prey biomass underpinned by changes in prey density or the average size of prey? Our results reveal fundamental similarities in predator and prey biomass scaling...
growth pattern influences predator-prey interactions and underpins pyramid shape. Several of these patterns are highly regular (R2 > 0.80) and yet are unexpected from classic …
Refuge-mediated predator–prey dynamics and biomass pyramids
2018年4月1日 · In this paper, we develop a model describing the predator–prey interactions when prey have access to a refuge. We investigate the effects of the prey refuge on the …

(PDF) The predator-prey power law: Biomass scaling
2015年9月4日 · We find that predator and prey biomass follow a general scaling law with exponents consistently near 3⁄4. This pervasive pattern implies that the structure of the biomass pyramid becomes ...
Modeling inverted biomass pyramids and refuges in ecosystems
2009年6月10日 · We devise predator–prey models to describe three mechanisms that can lead to IBPs: (1) well-mixed populations with large prey turn-over rate, (2) well-mixed populations with …
The predator-prey power law: Biomass scaling across terrestrial …
We show a robust scaling law that emerges uniquely at the level of whole ecosystems and is conserved across terrestrial and aquatic biomes worldwide. This pattern describes the …
Pyramids and cascades: a synthesis of food chain functioning and ...
Food chain theory is one of the cornerstones of ecology, providing many of its basic predictions, such as biomass pyramids, trophic cascades and predator–prey oscillations. Yet, ninety years …
Refuge-mediated predator–prey dynamics and biomass pyramids
2018年4月1日 · First, we study the effects of refuge on predator–prey dynamics and on biomass pyramids. Secondly, we investigate the impacts of fishing and predator migration on refuge …
