Summary: Understanding the energy requirements and prey consumption of Arctic predators, particularly the bowhead whale in Disko Bay, is crucial for assessing their vulnerability to climate change. Using unmanned aerial vehicle photogrammetry, researchers measured the body size and condition of bowhead whales to quantify their energy requirements and prey consumption. The study found that the body condition of adult whales increased over time and their energy requirements and prey consumption were correlated with body length.

Summary: This study aims to understand the physiology and condition of Antarctic krill, particularly juvenile krill, during winter. The researchers found that juvenile krill maintain high respiration rates and respond positively to increased food concentrations during winter. They rely on lipid stores accumulated in summer and autumn to survive the winter. The health of juvenile krill during winter depends on their ability to accumulate lipid reserves and find sufficient food, making changes in food availability a potential issue for them.

Summary: A major limitation of dietary toxicity studies on rodents is the variation in food consumption between treatments, which can impact study outcomes. Models based on dynamic energy budget theory offer a solution by separating chemical stress and food consumption inputs to understand their effects on growth rate. A new method for calculating feeding input f, based on observed relationships between food consumption and body size, shows promise in improving model accuracy in toxicology studies.

Summary: This study investigated the impact of urbanization on individual damselflies by examining variables such as body mass, wing spot size and energy reserves. The results showed no relation between these variables and the degree of urbanization, suggesting the resilience of rubyspot damselflies in urban environments. This finding has important implications for insect conservation, emphasizing the need to design cities that promote the presence and conservation of insect species.

Summary: Individual performance determines population dynamics. The condition index, a measure of individual performance, has been recommended as a tool in fisheries management and conservation. However, the lack of understanding of the relationship between individual-level processes and population-level responses hinders its adoption. In this study, we use composite modeling to link individual condition to population status and explore the effects of fishing pressure on the condition index.

Summary: This study used Yellowfin Bream as a case study to quantify potential errors in consumption and growth rate estimates when using diet data from different regions and times. The results showed a large uncertainty in consumption rate estimates due to diet diversity, emphasizing the need for caution when considering bioenergetic results among locations, times, and ontogeny.

Summary: Time-restricted feeding (TRF) is an effective dietary intervention for weight loss through negative energy balance. This study found that TRF increased fecal energy loss and showed a trend in increasing urine energy loss without affecting energy expenditure. TRF also improved glycemic profiles, heart rate, respiration rate, and metabolic flexibility.

Summary: This study investigated the effects of feeding ration on the growth, physiology, carbon allocation, energy budget, and CO2 fluxes of sea cucumber. The results showed that a feeding ration of 3% led to the highest specific growth rate, while a ration of 7% resulted in negative growth. Feeding ration significantly influenced carbon intake, nitrogen intake, and energy intake. The findings provide a theoretical basis for the development of efficient low-carbon aquaculture technology and sustainable industry.

Summary: Time-restricted feeding is crucial for weight management as it affects metabolism, but previous studies have often confused feeding time with fasting time; Researchers have introduced a new time-optimized feeding plan to better analyze the effects of meal timing on the body, and to more accurately simulate human eating patterns in the laboratory; According to the data, controlling the timing of carbohydrate and fat oxidation can effectively limit fat accumulation.

Summary: The use of Body Condition Score (BCS) has become a common and reliable tool to assess the health and nutritional status of animals in lab-animal science. However, the current BCS criteria are not directly applicable to clawed frogs (Xenopus laevis) due to their intracoelomic fat body. This study aimed to establish a species-specific BCS for clawed frogs and improve the housing conditions in lab-animal facilities.

Summary: The research showed that low light and feeding did not have a synergistic or additive effect in mitigating the negative impacts of elevated temperature on coral physiology and carbon budgets. Instead, the effects were species-specific and feeding alone was critical for meeting metabolic demand at elevated temperatures.

Summary: Time-restricted feeding and continuous calorie restriction have similar effects on gut peptides involved in satiety, but the former may reduce hunger. Current research is still lacking, and more evidence and studies are needed to draw definitive conclusions.

Summary: The study reveals that black-and-white ruffed lemurs primarily feed on fruits, but shift towards a folivorous diet during fruit-lean seasons. They also reduce activity time, increase resting time, and prefer higher canopy levels during this period for thermoregulation benefits.

Summary: The common jellyfish Aurelia spp. has a significant predation impact on zooplankton in coastal regions. A bioenergetic model based on ingested food and respiration was used to understand the growth of Aurelia spp. The model shows good agreement with data in well-fed conditions, but departs from the data when prey concentrations are suboptimal and fluctuating.

Summary: Demosponges are filter-feeding organisms composed of modular units. The filtration rate of demosponges is related to their size, but the relationship varies depending on the type of sponge. Small single-osculum sponges exhibit a scaling relation between filtration rate and volume, while multi-oscula sponges and large single-osculum sponges have different scaling relationships. The observed decline in volume-specific filtration rate from small to large sizes is discussed.

Summary: Sponges, one of the earliest and simplest animal groups, share basic characteristics with other filter-feeding invertebrates. They are abundant in coastal regions where they filter water for food particles and play a crucial ecological role. Understanding the growth of sponges compared to other filter-feeders is important. Little is known about the growth rate of sponges, so a bioenergetic growth model was used to study their growth.

Summary: Filter-feeding invertebrates play a crucial role in the marine ecosystem, as they serve as essential links between suspended food particles and higher trophic levels. This review focuses on studying the growth of various filter-feeding organisms, such as sponges, jellyfish, bryozoans, polychaetes, copepods, bivalves, and ascideans. The growth of these organisms is analyzed using a bioenergetic growth model based on filtration and respiration rates. The findings suggest that the exponents in the model, which represent these rates, are often similar, and the size-specific growth rate of filter-feeding organisms may be exponential or a power function of time.
