Responses to Heat and Cold Stress02:45

Responses to Heat and Cold Stress

13.4K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Predator-Prey Interactions02:39

Predator-Prey Interactions

16.9K
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.

Temperature-Dependent Growth of Brook TroutThe growth of brook trout is closely influenced by water temperature. Experimental data demonstrate how trout weight changes over a 24-day period in response to varying water temperatures. At lower temperatures, such as 15.5 degrees Celsius, brook trout show significant weight gain. However, as the temperature increases, the amount of weight gained steadily decreases. At the highest temperature measured, 24.4 degrees Celsius, trout experience a net...

Temperature Dependence on Reaction Rate

The Collision Theory
Atoms, molecules, or ions must collide before they can react with each other. Atoms must be close together to form chemical bonds. This premise is the basis for a theory that explains many observations regarding chemical kinetics, including factors affecting reaction rates.
The collision theory is based on the postulates that (i) the reaction rate is proportional to the rate of reactant collisions, (ii) the reacting species collide in an orientation allowing contact between...

Increased Body Temperature01:25

Increased Body Temperature

6.3K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Requirements for Human Life01:26

Requirements for Human Life

9.8K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Summary

Increased temperature variability, not just warming, hinders organisms' ability to adapt to predation. This impacts life history traits and population growth, posing a greater evolutionary risk.

Area of Science:

  • Ecology
  • Evolutionary Biology
  • Environmental Science

Background:

  • Life history evolution is linked to energy expenditure, which is influenced by temperature.
  • Rising temperature variability presents a novel environmental stressor for organisms.
  • Understanding responses to environmental variability is crucial for predicting species adaptation.

Purpose of the Study:

  • To investigate the effects of increased temperature variability on life history responses to predation risk.
  • To compare organismal responses under constant versus variable temperature regimes.
  • To assess the implications of temperature variability for population growth and inducible defenses.

Main Methods:

  • Experimental manipulation of temperature regimes (constant vs. variable).
  • Exposure of organisms to different predation risk levels.
  • Measurement of life history traits (e.g., neonate number/size, time to first brood) and population growth rate.
  • Assessment of inducible defense development.

Main Results:

  • Organisms under constant temperatures adjusted life history traits in response to predation risk.
  • Under variable temperatures, organisms failed to respond appropriately to predation risk.
  • Variable temperatures led to slower population growth rates.
  • Development of inducible defenses was impaired under variable temperatures.

Conclusions:

  • Increased temperature variability disrupts adaptive responses to ecological challenges like predation.
  • Failure to adjust life history and defenses under variable temperatures can slow population growth.
  • Temperature variability poses a more significant threat to species adaptation than a simple mean temperature shift.
