Digestibility of Common Forage Plants and Energetic Requirements of the Black-Tailed Prairie Dog
… from oxygen consumption tests and caloric requirements found in feeding trials. The prairie dog feeding trial results were 1.32 times greater than the RMR estimates.</p>

Determining the neuromuscular and energetic requirements of loaded and unloaded sprint efforts through experimental modeling new integrated approaches
… providing a more accurate representation of the energetic commitment required during sprints. Study 2 examines muscle activation patterns and the effects of various resistance sprints. Seventeen elite U17 soccer players completed sprints under unloaded and loaded conditions, with parachute and …

AMUR TIGER PREDATION AND ENERGETIC REQUIREMENTS IN THE RUSSIAN FAR EAST: NEW INSIGHTS FROM GLOBAL POSITIONING SYSTEM COLLARS
… drivers of tiger declines. Due to substantial energetic requirements, tigers can only survive and reproduce in areas with healthy prey populations. This may be particularly important for Amur tigers (P. t. altaica) in the Russian Far East, living at the northern limits and with the lowest prey …

How a Central-Place Forager (Callospermophilus lateralis) Modifies its Movement Behavior to Navigate a Risky Landscape and Maximize Fitness
… distribution of available seeds, and current energetic requirements were large factors in predicting where and how individuals traveled throughout their home ranges. Following winter torpor, energetic requirements were highest. The first seeds available existed in distinct clumps, not …

Form, function and flow in the plankton : jet propulsion and filtration by pelagic tunicates
… may be compensated by comparatively low energetic requirements.

On the mechanisms of substrate translocation by the ABC transporter MsbA
… assays, the detailed mechanisms and the energetics requirements of lipid transport by MsbA remain unclear. In this PhD project, I developed an in-vitro lipid transport assay for phospholipids with unmodified, long-acyl chains as well as for the hexa-acylated Lipid-A. To track these lipids …

The Relationship of Dominance, Reproductive State and Stress in a Non-Cooperative Breeder, The Domestic Horse (<em>Equus caballus</em>)
… a dominant position requires a high rate of energetically expensive aggressive displays and physical exertion. Lab based winnerloser studies, often conducted with individuals from non-social species, have shown that subordinates have higher stress hormone levels than dominant individuals …

Form, function and flow in the plankton : jet propulsion and filtration by pelagic tunicates
… may be compensated by comparatively low energetic requirements. Finally, a low Reynolds number mathematical model using accurately measured parameters and realistic oceanic particle size concentrations showed that submicron particles are encountered at higher rates than larger particles. …

Fluctuating human activity and associated anthropogenic food availability affect behaviour and parental care of Red-winged Starlings
… their offspring for maintaining their own energetic requirements, meaning that nestlings received less food on weekends. I also found that parents preferentially fed their nestlings natural food on week days, despite an increased availability of anthropogenic food. This suggests that, with …

The mechanism of collagenolysis : a substrate-centric view
… mechanism would in principle have large energetic requirements, but neither ATP nor other energy-rich molecules are necessary for collagenolysis. An alternative mechanism is that collagen exists in multiple states, some featuring structures that are unfolded in the vicinity of the …

The Role of Parkin-Mediated Mitophagy During Aging and Exercise in Skeletal Muscle
… mitochondria that are unable to sustain the energetic requirements of the cell are targeted for lysosomal degradation through a process termed mitophagy. Parkin is a ubiquitin ligase that is involved in mitophagy and the turnover of mitochondria. Parkin is extensively studied in neuronal …

Precise single cell monitoring reveals principles of cell growth
… cytokinesis. We next studied the metabolic and energetic requirements necessary for cell growth by monitoring immediate single cell growth response to nutrient depletion. To this end, we developed a method to gently exchange the fluid surrounding a cell while constantly monitoring cell growth. …

Redox-active materials for electrochemically-mediated separations
… recognition, reversible operation, and lower energetic requirements, all of which can be realized via only electrochemical stimuli without any chemical additives. In this work, the focused design of redox-active materials for imparting specific functionalities to electrosorption processes are …

The role of geophytes in stone age hunter-gatherer subsistence and human evolution in the greater cape floristic region
… driver in human evolution and supported the energetic requirements to sustain brain development throughout hominin evolution. Plants that possess underground storage organs (geophytes) have been put forward as the likely source of starch. Geophytes comprise a large portion of the plant …

Investigating the foraging ecology and energy requirements of a seabird population increasing in an intensely exploited marine environment
Their high energetic demands make seabirds sensitive to changes in prey availability, which is often reflected in their diet and energetic expenditure during breeding. Populations of the three seabirds endemic to southern Africa's Benguela upwelling ecosystem that rely on small pelagic fish have …

Feeding habits of the yellowtail flounder and production of its invertebrate prey on Georges Bank
… flounder was calculated by two methods. The bioenergetic method sums the food required to satisfy the energetic requirements of the fish. The second method is based on the weight of stomach contents and the rate of food evacuation from the stomach. The bioenergetic method gave consistently …
