Sentences with phrase «disease leading to the extinction»

Not exact matches

The study has found that Darwin's frogs are infected with the fungal pathogen Batrachochytrium dendrobatidis (Bd), and despite an absence of obvious mortality researchers have noted population declines, leading them to believe that these infected populations are at a serious risk of extinction within 15 years of contracting the disease.

The disease caused by Bd, chytridiomycosis, has led to the recent decline or extinction of 200 frog species worldwide.

Importantly, these threats have led to tiger populations becoming smaller and more fragmented, making them much more susceptible to sudden population declines and even extinction due to disease.

If left unchecked, the disease could cause a further devastating reduction in the Mongolian saiga population, and potentially lead to extinction.

It makes places uninhabitable for some plants and animals, leading to extinctions and redistribution of species, threatening food production with alien pests and diseases.

But other elements could potentially also contribute to a collapse: an accelerating extinction of animal and plant populations and species, which could lead to a loss of ecosystem services essential for human survival; land degradation and land - use change; a pole - to - pole spread of toxic compounds; ocean acidification and eutrophication (dead zones); worsening of some aspects of the epidemiological environment (factors that make human populations susceptible to infectious diseases); depletion of increasingly scarce resources [6,7], including especially groundwater, which is being overexploited in many key agricultural areas [8]; and resource wars [9].
