Summary: Metabolic theory aims to address ecological and evolutionary issues by incorporating physical principles of energy and mass exchange, with individual growth models being the fundamental basis. There is confusion and controversy surrounding the origins, application, logical consistency, and realism of these models. Putter's original insights have influenced subsequent growth theories, such as von Bertalanffy's and the DEB theory, leading to advancements in understanding metabolic patterns at the individual level.

Summary: We investigated the connection between biological energy utilization rates and the biomass sustained by this energy utilization at both organism and biosphere levels. By compiling a dataset consisting of over 10,000 measurements of metabolic rates from more than 2,900 species, and quantifying energy utilization rates on a biomass-normalized basis for different components of the biosphere, we found that energy utilization rates vary greatly. The correlation between mass-normalized energy utilization rates and biomass carbon turnover rates suggests global mean turnover rates for terrestrial soil biota, marine water column biota, and marine sediment biota.

Summary: The krill Nyctiphanes australis is the most abundant and ecologically important euphausiid in southern Australia and New Zealand coastal and shelf waters. The species lives in coastal environments which are currently susceptible to shifts in temperature and productivity. The study used Dynamic Energy Budget models (DEB) to analyze the temperature and food dependency of growth and reproduction of Nyctiphanes species. The results show that higher temperatures and low food levels may decrease the energetic content and diameter of the eggs, potentially leading to a decline in N. australis populations and affecting coastal marine ecosystems and inshore fisheries.

Summary: This study uses single-cell FRET measurements of pyruvate levels to discover large periodic fluctuations in bacterial glycolysis when starved E. coli is exposed to glycolytic sources. These fluctuations are primarily controlled by biochemical reactions around the pyruvate node and propagate to other cellular processes, potentially leading to temporal heterogeneity of cellular states within a population.

Summary: Understanding the interactions among multiple stressors is crucial for ecological risk assessment and ecosystem management, although collecting empirical data for all interactions is often impractical. Results from a study on chemical stressors and inter-specific competition impacting greenback cutthroat trout revealed that chemical exposure was the major stressor in colder temperatures, while competition mostly affected the trout population in warmer environments. Individual-level effects of stressors were not predictive of the type of interactions between stressors at the population level, which varied between temperature scenarios.

Summary: DNA metabarcoding methods have been used to quantify marine benthic biodiversity, but the relationship between DNA sequences of a species and its biomass/abundance is still complicated. This study compared traditional morphological approaches with molecular approaches to estimate abundance and biomass of benthic intertidal mudflat samples, finding a relationship between biomass and read abundance for some annelid taxa. The quantification of abundance and biomass using molecular approaches is hindered by DNA ecology and the compositional nature of sequencing data.

Summary: This study focuses on the energetics and Dynamic Energy Budget (DEB) parameters of chondrichthyans, with the aim of understanding the characteristics and differences among different species. The results show that the mass of neonates as a fraction of the mother's mass is a key factor influencing the inter-specific scatter in ultimate reproduction rate. Additionally, the study reveals that chondrichthyans can be classified as demand-species (sharks and rays) or supply-species (ray-finned fish and chimaeras) based on their energy consumption patterns.

Summary: The flatfish nursery function in the Wadden Sea has been affected by increased seawater temperature, leading to changes in settling, habitat suitability, and growth performance of flatfish species. Some age groups of plaice, flounder, and dab have disappeared or decreased in density, while 0-group sole has shown increased growth. The rise in water temperatures and abundance of predators have also resulted in increased mortality rates for 0-group plaice. The decrease in density of juvenile plaice and dab in the Wadden Sea has not impacted recruitment to North Sea stocks, suggesting other areas have taken over the nursery function. However, the predicted increase in seawater temperature may further reduce the growth potential of plaice and dab and ultimately lead to their disappearance from the Wadden Sea.

Summary: Populations of large fish in the North Sea have recently started to increase, possibly due to reduced fishing pressure. However, the recovery of these populations needs to be viewed in a long-term perspective. A study on the critically endangered common skate species complex found that its current abundance is still below historical levels and limited to the northern North Sea.

Summary: This study simulates the survival of early life stages of NEA cod and haddock under the combined influence of natural processes and pollutants, and investigates the impact on adult fish populations in the event of a major oil spill. The research shows how dynamic ocean processes control the magnitude of population losses due to an oil spill, with the largest impacts occurring during the initial rise in marine productivity and spawning season. The reproductive health of adult fish populations remained unaffected in all scenarios.

Summary: Spatial variability in fish food-web structure in the Wadden Sea was studied by comparing stomach content and bulk stable isotopes of fish species caught in the Ems and Marsdiep basins. The findings showed that most fish species in both basins were generalist feeders, with a few key prey species driving the food web. The study also revealed spatial differences in prey preferences, which were likely influenced by local predator and prey abundances.

Summary: Community analysis revealed significant changes in the abundance, biomass, and spatial distribution of macrofauna communities in the East-Frisian Wadden Sea from the 1980s to 2018, likely in response to environmental changes and anthropogenic stressors. The total abundance and biomass decreased, particularly in the eastern regions of the study site, possibly due to de-eutrophication processes. However, the abundance and biomass of the invasive bivalve Ensis leei increased significantly.

Summary: Birds, including the bobwhite quail, undergo tissue remodeling and energy allocation during reproduction. This study utilized a Dynamic Energy Budget model to investigate the energy fluxes associated with reproduction in bobwhite quail. The results suggest that energy is primarily used to fuel the metabolic costs of building and maintaining the reproductive system, rather than directly for egg production. This model has implications for studying avian physiology, quail management, and conservation efforts.
