Why is functional biodiversity important?

Functional diversity is of ecological importance because it, by definition, is the component of diversity that influences ecosystem dynamics, stability, productivity, nutrient balance, and other aspects of ecosystem functioning.

What is a functional biodiversity?

Functional biodiversity refers to the set of species that contribute to ecosystem services in an agroecosystem. In other words, it is the biodiversity that is useful to farmers. It provides benefits that can be valued by the farmer through environmental management.

Why are functional traits important?

A need to develop better predictive capacity for how species respond to environmental change has in part motivated this focus. Functional traits are of most interest—those with a defined link to individual survival, development, growth and reproduction.

What is functional diversity and how do we care?

Functional diversity is a relatively nuanced way of comparing organisms based on their ecological differences, but its not a panacea. It may depend strongly on which traits are considered, interactions among multiple traits, and what the goals of the analysis are (and whether they may change).

Which of the following is an example of functional diversity?

Some examples include understanding species competitive abilities, patterns of species co-occurrence, community assembly, and the role of different traits on ecosystem functioning.

What are the benefits of biodiversity?

A healthy biodiversity offers many natural services

  • Protection of water resources.
  • Soils formation and protection.
  • Nutrient storage and recycling.
  • Pollution breakdown and absorption.
  • Contribution to climate stability.
  • Maintenance of ecosystems.
  • Recovery from unpredictable events.

How does the diversity of species within a functional type affect ecosystem processes?

If those resources limit growth, then increasing functional richness should lead to greater total productivity and decreased loss of resources from the ecosystem. Facilitative interactions among species could also lead to increases in ecosystem pools or process rates as species or functional richness increase.

What is a functional species?

From Wikipedia, the free encyclopedia. A functional group is merely a set of species, or collection of organisms, that share alike characteristics within a community. Ideally, the lifeforms would perform equivalent tasks based on domain forces, rather than a common ancestor or evolutionary relationship.

What is a plant functional trait?

Plant functional traits are defined as any morpho-, physio-, and phenological plant characteristics affecting overall plant fitness through their influence on survival, growth, and reproduction (Violle et al., 2007).

What are effects traits?

Trait-based approaches evaluate ecosystem functioning under environmental change by relating traits predicting changes in species densities (response traits) to traits driving ecosystem functioning (effect traits).

Why are diverse ecosystems important?

Biodiversity boosts ecosystem productivity where each species, no matter how small, has an important role to play. … A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all forms of life.

How is functional diversity measured?

Functional diversity metrics are calculated by associating species-by-site matrices, such as presence-absence or abundance of species, to the species’ functional traits; i.e. morphological or behavioural traits that are related to the role the species may perform in the ecosystem [5•].

What happens to ecosystem health when functional diversity declines?

Declining biodiversity lowers an ecosystem’s productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem’s services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).

What is alpha diversity and beta diversity?

Alpha diversity refers to the average species diversity in a habitat or specific area. Alpha diversity is a local measure. Beta diversity refers to the ratio between local or alpha diversity and regional diversity. This is the diversity of species between two habitats or regions.

How are ecosystems where amphibians and other species live functioning examples of the three scientific principles of sustainability?

How are ecosystems and the variety of species they contain related to the three principles of sustainability? They depend on solar energy and on the cycling of nutrients. Ecosystems also help to sustain biodiversity.
