Ecological Disturbance02:26

Ecological Disturbance

21.3K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Threats to Biodiversity

27.6K
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...

Mutation, Gene Flow, and Genetic Drift01:09

Mutation, Gene Flow, and Genetic Drift

65.2K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).

Predator-Prey Interactions02:39

Predator-Prey Interactions

22.0K
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.

Osmoregulation in Insects01:47

Osmoregulation in Insects

17.8K
Malpighian tubules are specialized structures found in the digestive systems of many arthropods, including most insects, that handle excretion and osmoregulation. The tubules are typically arranged in pairs and have a convoluted structure that increases their surface area.

What is Natural Selection?01:32

What is Natural Selection?

131.3K
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.

Area of Science:

  • Ecology
  • Environmental Science
  • Entomology

Background:

  • Insects face numerous global change drivers, including habitat fragmentation, agricultural intensification, pollution, and climate change.
  • Previous research often focused on single stressors, limiting a comprehensive understanding of cumulative impacts on insect populations.

Purpose of the Study:

  • To provide an overview of recent developments in insect response to global change drivers.
  • To synthesize findings on major insect functional groups and their interactions with other organisms.
  • To cover major global change drivers, both individually and in combination.

Main Methods:

  • Literature review of recent developments in the field.
  • Focus on main functional groups of insects and their interactions.
  • Inclusion of all major global change drivers (landscape modification, climate change, agricultural management) singly and in interaction.

Main Results:

  • Recent research increasingly employs multi-factor manipulations to study insect responses.
  • Linkages between different research subdisciplines (e.g., habitat destruction, climate change) are becoming more recognized.
  • The review covers interactions among various global change drivers and their effects on insects.

Conclusions:

  • A comprehensive understanding requires studying multiple global change drivers and their interactions.
  • Future research should focus on integrating findings across subdisciplines.
  • Statistical and conceptual frameworks are needed to effectively analyze interactions in ecological studies of insects.
