Latitudinální proměna ideálního stromu podle metabolické teorie
… similar questions by working in a framework of metabolic theory of ecology. Considering diameter-height relationship scaling models predict a scaling coefficient (slope of a regression line on log-log scale) β = 2/3, others β = 2 to 3. For diameter-standing leaf biomass relationship I found in …

Changing consumer strength in a changing climate
… Ocean warming and acidification alter the metabolic demands of organisms and the strength at which they interact with each other. The metabolic costs of changing abiotic conditions vary between interacting pairs of species, and as such, their strength of influence on one another may change …

Towards a Temporal Theory of Ecology: Body Mass Role for Activity Patterns of North American Artiodactyls
… the evolutionary trajectory of a species. The metabolic theory of ecology links body mass to multiple ecological traits. This study seeks to extend these insights to activity patterns at a macroecological scale, using the large repository of camera trap dataset to explore the relationship …

Energy Flow in a Floodplain Aquifer Ecosystem
… lower than the ¾ power scaling predicted by metabolic theory. Invertebrate production was dominated by copepods (Diacyclops, Acanthocyclops, Bryocamptus), Stygobromus amphipods, and amphibiont stoneflies, and ranged from 26.9 to 4200 mg C/m3 sediment/year. Production and density showed a …

Body Size Histories in Cenozoic Reptiles From Global to Community Scales
… temperatures, which support predictions from metabolic theory. Conflicting relationships between size and temperature observed in the past and present suggest that, across the Cenozoic, the influence of temperature was superseded by other factors facilitating size increase. Such factors …

Latitudinal variation in plankton size spectra along the Atlantic Ocean
… relationships that exist between body mass and metabolic activity, and between body mass and the ecological regulation of population density. In this way, plankton size has an important role in structuring the rates and pathways of material transfer in the marine pelagic food web, and …

The Impacts of Disruptive Environmental Change on Vital Microbial Ecosystems
… a mix of experiments, observational studies, and theory, we investigate the dynamic interplay between microbes and their changing environment.</p><p>In our first research chapter, we address these questions using data from a longterm whole-ecosystem warming experiment at a boreal peatland. We …

The Effect of Spatial and Environmental Drivers on Patterns in Species Richness and Composition
… have been initiated by island biogeography. Theory on island biogeography has particularly been improved by a better representation of time related components including speciation and environmental change. Oceanic islands are not stable systems but follow a characteristic ontogeny. After the …

Inter-individual variation within social groups: how metabolic rate shapes the pace of life
Metabolic rate (MR) is often cited as the fundamental rate which determines the rate of all biological processes by shaping energetic availability for the various physiological, behavioral, and life-history traits that contribute to performance. Furthermore, the metabolic theory of ecology posits …

La Metabolomica: una nuova era in Cardiologia. Le nostre esperienze originali nei campi dell' insufficienza cardiaca, della cardiopatia ischemica e dell' ipertensione polmonare
… of a broad range of metabolites providing a metabolic picture able to identify metabolic changes. On these basis we carried out a metabolomics on three settings of cardiovascular diseases: a) heart failure; b) Stable coronary artery disease; c) Pulmonary hypertension in systemic sclerosis. …
