Global Climate Change01:50

Global Climate Change

24.7K
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.

Threats to Biodiversity

22.9K
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...

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Responses to Heat and Cold Stress

13.8K
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.

Osmoregulation in Insects01:47

Osmoregulation in Insects

16.7K
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.

Frequency-dependent Selection01:21

Frequency-dependent Selection

22.2K
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.

Summary

Flying insect populations declined dramatically in a pristine Colorado meadow over 20 years. Rising summer temperatures, especially nighttime lows, are linked to this alarming 72.4% decrease in insect abundance.

Area of Science:

  • Ecology
  • Entomology
  • Climate Change Research

Background:

  • Global insect declines threaten ecosystem stability and services.
  • Impacts on less-disturbed ecosystems remain understudied.
  • Subalpine meadows are sensitive indicators of environmental change.

Purpose of the Study:

  • To quantify flying insect abundance trends in a relatively pristine subalpine meadow.
  • To investigate the relationship between insect declines and weather variables.
  • To identify potential drivers of insect population changes in undisturbed environments.

Main Methods:

  • Collected flying insect abundance data over 15 seasons (2004-2024).
  • Utilized 38 years of local weather data.
  • Applied information-theoretic analysis to model weather-related factors influencing insect abundance.

Main Results:

  • Annual insect abundance declined by an average of 6.6%, totaling a 72.4% decrease over 20 years.
  • Increased previous summer temperatures, particularly daily minimums, correlated with seasonal insect declines.
  • Rising summer temperatures (0.8°C per decade) are a significant factor in long-term insect loss.

Conclusions:

  • Significant insect declines are occurring even in relatively pristine ecosystems.
  • Climate change, specifically warming summer temperatures, is a key driver of these declines.
  • Precipitous insect loss jeopardizes ecosystem functions like pollination and nutrient cycling.
