Can biodiversity help prevent the spread of plant diseases?

Burgeoning research has shown that high biodiversity frequently reduces rates of pathogen transmission and lowers disease risk for human beings, wildlife, livestock, and plants.

How does biodiversity affect disease?

Biodiversity probably has little net effect on most human infectious diseases but, when it does have an effect, observation and basic logic suggest that biodiversity will be more likely to increase than to decrease infectious disease risk.

Does biodiversity prevent disease?

Biodiversity protects ecosystems against infectious diseases, researchers have concluded. The finding suggests that loss of species from an environment could have dangerous consequences for the spread and incidence of infections, including those that affect humans.

Why does biodiversity prevent disease?

Two decades ago, we proposed that innate biodiversity can reduce the risk of infectious diseases through a dilution effect, in which species in diverse communities dilute the impact of host species that thrive when diversity declines (43).

Does biodiversity loss leads to an increased disease risk?

Several studies suggest that with the loss of biodiversity the transmission of diseases increases (Keesing et al. 2010). Thus biodiversity loss causes the loss of an important ecosystem service: buffering the spreading of infectious diseases to humans, animals and plants (Pongsiri et al.

How does biodiversity loss affect the spread of infectious diseases?

Wildlife hosts represent both habitat and resources for infectious disease agents; therefore, if biodiversity loss causes a reduction in host abundance, these disease agents may decline alongside their hosts.

Why is biodiversity important?

Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

How does high biodiversity help the stability of an ecosystem?

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

What are the effects of biodiversity loss?

Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.

What is diversity and biodiversity?

The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.

Why is biodiversity important 5 Reasons?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have 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 life forms.

How does biodiversity increase and decrease?

An area’s biodiversity increases and decreases with natural cycles. Seasonal changes, such as the onset of spring, create opportunities for feeding and breeding, increasing biodiversity as the populations of many species rise.
