Summary
Elk metabolism decreases in winter, with activity linked to temperature and food energy. This study quantifies these physiological changes in Vyatka taiga elk.
Area of Science:
- Zoology
- Physiology
- Ecology
Context:
- Winter conditions in the Vyatka taiga present unique challenges for elk survival.
- Understanding energy balance is crucial for wildlife management and conservation efforts.
Purpose:
- To investigate the morphometric and physiological parameters of elk during winter.
- To analyze metabolic rate, energy balance, and activity patterns in relation to environmental factors.
Summary:
- This study examined 170 elk, measuring morphometric parameters and calculating physiological indicators like specific metabolism and heat loss.
- Specific metabolism decreased from early to late winter in model elk (calf, male, female).
- Elk activity rhythms correlated with daily air temperature, and flight distance depended on energy intake.
Impact:
- Provides baseline data on elk physiology during winter, aiding in understanding their adaptation strategies.
- Highlights the relationship between environmental conditions, energy balance, and behavior in large herbivores.
- Informs conservation and management plans for elk populations in taiga ecosystems.

00:48Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

00:53Migration
9.1K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

01:32What is Natural Selection?
132.6K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

02:39Predator-Prey Interactions
22.3K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

01:50Threats to Biodiversity
27.8K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

01:57Adaptations that Reduce Water Loss
28.9K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
