Responses to Drought and Flooding

10.6K
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

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...

Adaptations that Reduce Water Loss

25.2K
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.

Summary

Climate change negatively impacts wild bee fitness. Drought and heat reduce solitary bee reproduction by decreasing floral resources and directly affecting individual bees.

Area of Science:

  • Ecology
  • Climate Change Biology
  • Conservation Biology

Background:

  • Wild bees are crucial for ecosystems, but many species are declining.
  • Climate change is a major driver of these declines, impacting bees directly and indirectly through food resources.
  • Understanding local-scale impacts on individual bee fitness is key to explaining broad-scale population changes.

Purpose of the Study:

  • To investigate how local climate variations affect the individual fitness of five solitary bee species (genus Osmia).
  • To determine the direct and indirect (floral resource-mediated) effects of climate variables on bee reproductive output.

Main Methods:

  • Long-term monitoring (9 years) of brood cell production in over 700 individual female Osmia bees.
  • Surveys of floral abundance, considering species-specific host plants, across seven subalpine sites.
  • Recording local temperature and precipitation data to correlate with bee reproductive success.

Main Results:

  • Increased drought severity and high temperatures significantly reduced the total brood cells produced by nesting female bees.
  • Reduced floral host-plant availability in hotter, drier years partially mediated the negative impact of climate on bee reproduction.
  • Both direct physiological stress and indirect resource limitation contribute to climate change impacts on bee fitness.

Conclusions:

  • Climate change, particularly drought and heat, has direct and indirect negative effects on the fitness of solitary bees.
  • Floral resource availability is a critical factor mediating climate change impacts on bee populations.
  • Projected warming and drying trends are likely to negatively affect the demographic success of these solitary bees.
