B71 - Population Dynamics for Trophic Biomass Pyramid Invasive species that do not rely on ecosystem gaps are poorly understood, yet they pose serious threats to ecosystem health. Author(s): Selini ...

A pyramid of biomass shows the mass - in grams or kilograms - of the population of the trophic levels in a food chain. Converting the two previous pyramids of number into biomass means they look ...

The findings, published in the journal Current Biology, external, are an example of an "inverted trophic pyramid": the average biomass in the channel is skewed towards predators rather than prey.

Once fish biomass goes below 665 kilograms per hectare, trophic pyramids lose the hourglass shape that allows them to transfer energy quickly and efficiently, according to the research.

Increasing temperature and productivity change biomass, trophic pyramids and community‐level omega‐3 fatty acid content in subarctic lake food webs. Global Change Biology , 2020; DOI: 10.1111 ...

With a current estimate of ~1,000 million tons, mesopelagic fishes likely dominate the world total fishes biomass. However, recent acoustic observations show that mesopelagic fishes biomass could ...
