Biomass‐to‐volume ratio as a central continuous functional trait for marine zooplankton

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2673-2687, September 2025.
Abstract Gelatinous zooplankton are an important component of many ecosystems and important for ecosystem structure and carbon cycling. However, this group is generally not considered in biogeochemical models. Here we investigate the biomass‐to‐volume ratio as an underappreciated “master trait” that allows for the incorporation of a large diversity of ...

The contribution of metabolic theory to ecology

open access: yesEcological Monographs, Volume 95, Issue 3, August 2025.
Abstract The metabolic theory of ecology (MTE) has been an important strand in ecology for almost a quarter of a century, renewing interest in the importance of body size and the role of energy. The core of the MTE is a hydrodynamic model of the vertebrate cardiovascular system that predicts allometric scaling of metabolic rate with exponents in the ...

On Coelenterata: Validation and Des­cription of the Superphylum Coelenterata (Leuckart, 1847)

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2017
It has been suggested to combine the following three phyla of lower invertebrates in the superphylum Coelenterata (Leuckart, 1847): Plathelminthes Schneider, 1873, Cnidaria (Leuckart, 1847), and Ctenophora (Leuckart, 1847).
