Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

120
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Frequency-dependent Selection01:21

Frequency-dependent Selection

22.0K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Global Climate Change01:50

Global Climate Change

24.3K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Responses to Heat and Cold Stress

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.

Threats to Biodiversity01:50

Threats to Biodiversity

22.2K
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...

Summary

Climate change significantly impacts insects, particularly hyperparasitoids, due to their sensitive life histories. More research is urgently needed to understand these effects on insect populations and biological control.

Area of Science:

  • Ecology
  • Entomology
  • Climate Change Biology

Background:

  • Anthropogenic climate change, characterized by rising temperatures and extreme weather events, profoundly affects insect physiology, phenology, behavior, populations, and communities.
  • Hyperparasitoids, insects developing on primary parasitoid hosts, are particularly vulnerable due to traits like low fecundity, slow development, small population sizes, and their position high in the food chain.

Purpose of the Study:

  • To review existing evidence on the direct and indirect impacts of temperature and climate change on hyperparasitoid populations.
  • To discuss the potential feedback mechanisms of hyperparasitoid responses on ecological communities and biological control programs.

Main Methods:

  • Literature review synthesizing data on temperature and climate-related effects on hyperparasitoids.
  • Focus on impacts mediated through plants, herbivores, and primary parasitoid hosts, especially at higher temperatures.

Main Results:

  • Evidence suggests significant direct and indirect effects of climate change on hyperparasitoid populations.
  • Cascading effects through lower trophic levels and host-parasitoid interactions are key pathways of impact.

Conclusions:

  • Despite their ecological importance, the effects of climate change on hyperparasitoids remain largely understudied.
  • Further research is crucial to predict and mitigate potential disruptions to insect communities and biological control services.
