Key causes of the decline included habitat loss and conversion to intensive agriculture and urbanization, pollution, particularly from pesticides and fertilizers, as well as biological factors, such as pathogens and introduced species and climate change.
What factors can make the beetles population decrease?
Possible causes of the decline have been identified as habitat destruction, including intensive agriculture, the use of pesticides (particularly insecticides), urbanization, and industrialization; introduced species; and climate change.
What is causing insect decline?
Insects are declining in abundance in many parts of the world, and species are being lost at a rapid rate, especially through the felling of tropical trees. Scientists warn that these declines and losses are undermining the ecosystems on which many lives depend. One of the known root causes is habitat loss.
Whats causing the sharp decline in insects and why it matters?
Scientists cite many factors in the fall-off of the worlds insect populations, but chief among them are the ubiquitous use of pesticides, the spread of monoculture crops such as corn and soybeans, urbanization, and habitat destruction.
Why is the burying beetle endangered?
— The U.S. Fish and Wildlife Service has announced the downlisting of the American burying beetle from endangered to threatened despite the absence of the beetle from most of its range, ongoing habitat destruction from the oil and gas industry, and new information that climate change is decimating the species in the ...

How has climate change contributed to bark beetle attacks?
With continued changes in climate, many tree species will be exposed to conditions that are potentially less suitable for optimal growth, thereby making them more susceptible to bark beetle attacks.
Were there giant bugs in prehistoric times?
Giant insects ruled the prehistoric skies during periods when Earths atmosphere was rich in oxygen. Insects reached their biggest sizes about 300 million years ago during the late Carboniferous and early Permian periods.
Are insects really disappearing?
Insects are the most abundant group of animals on the planet. There are an estimated 10 quintillion of them on Earth. But in recent years, scientists have found disturbing evidence that insect populations are on the decline around the world.
Can burying beetle fly?
Like many parents around the world, burying beetles provide a cozy nursery for their offspring. Unlike most parents, however, Nicrophorus vespilloides beetles build that nursery by plucking fur and feathers from small animal carcasses and then coating the bare bodies with special secretions.

What eats the American burying beetle?
Prey species were generally less plentiful. Widespread cutting of forests increased edge habitat, which led to more predators and scavengers such as foxes, raccoons, opossums, skunks and crows. All competed with the beetles for carrion. The optimum-sized, carrion food-base was reduced throughout the beetles range.
