Responses to Drought and Flooding

11.8K
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.

Adaptations that Reduce Water Loss

27.8K
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.

Ecological Disturbance02:26

Ecological Disturbance

20.6K
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.

Precipitation Processes01:12

Precipitation Processes

4.5K
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...

Ecological Succession02:17

Ecological Succession

21.1K
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Precipitation and Co-precipitation

4.0K
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...

Summary

Extreme climatic events impact ecosystems more than average changes. Ecosystem responses vary geographically, making broad predictions difficult, especially in diverse tropical regions.

Area of Science:

  • Ecology
  • Climate Change Biology
  • Ecosystem Science

Background:

  • Ecosystems may be more sensitive to extreme climatic events than to gradual changes in mean conditions.
  • Previous studies on ecosystem responses to climatic variability were geographically and biologically limited.
  • Understanding geographic and biological scope is crucial for interpreting varied experimental results.

Purpose of the Study:

  • To investigate the sensitivity of aquatic ecosystems within tank bromeliads to rainfall manipulation across the Neotropics.
  • To characterize ecosystem responses based on invertebrate functional composition, biological stocks, and ecosystem fluxes.
  • To determine if ecosystem responses to rainfall variation differ based on geographic location and local species composition.

Main Methods:

  • Rainfall was manipulated in tank bromeliads across seven Neotropical sites.
  • Aquatic ecosystem responses were assessed by analyzing invertebrate functional composition, biomass, bacterial density, decomposition, carbon, and nitrogen.
  • Hydrology within bromeliads and taxonomic composition of functional groups were considered to explain site-specific differences.

Main Results:

  • Invertebrate functional composition was the most sensitive response metric, despite the presence of drought-tolerant families.
  • Total invertebrate biomass showed universal insensitivity due to averaging of opposing responses between functional groups.
  • Rainfall effects on invertebrate functional composition varied geographically due to site-specific hydrology and differing family responses.

Conclusions:

  • Establishing universal thresholds for 'safe ecosystem functioning' is challenging due to differing sensitivities of ecosystem components and geographic variability.
  • Ecological forecasts for climate change may be spatially restricted, particularly in tropical systems with high species turnover and mediated habitat impacts.
  • Habitat properties significantly mediate climatic impacts, influencing the applicability of ecosystem response thresholds across diverse geographic locations.
