From RUTGERS UNIVERSITY and the YGTBFKM department. I laughed out loud when I saw this study title. My first thought: Other than these researchers, who gives a flying roach (an arthropod) about how bugs were affected by a hurricane in New York City? There’s far bigger issues to worry about and insects are tremendously resilient. Who funds this junk? The answer is below. SMH.
Urban insects are more resilient in extreme weather
Rutgers University-Camden rersearch examins how arthropods survive hurricanes in urban centers
CAMDEN – A study led by Amy Savage, a Rutgers University-Camden assistant professor of biology, will help researchers understand how to make predictions and conservation decisions about how organisms living in cities will respond to catastrophic weather events.
Savage’s analysis, conducted in New York City, compared the diversity of arthropods – insects such as ants, bees, beetles, and wasps – that were living in parks and street medians before and after Hurricane Sandy, which ravaged parts of New Jersey and New York in 2012.
The study, “Homogenizing an Urban Habitat Mosaic: Arthropod diversity declines in New York City parks after Super Storm Sandy,” was published in the journal Ecological Applications.
The study shows that before the storm, the diversity was higher in the parks than in street medians. After the storm, arthropod diversity in the parks declined, resulting in communities in parks becoming indistinguishable from those in street medians. In other words, the higher diversity detected in parks before the storm was absent from post-storm samples.
According to the Rutgers-Camden researcher, the study supports the hypothesis that organisms living in high-stress urban medians possess adaptions to disturbance, making them more resilient to the effects of extreme weather events than organisms living in relatively low-stress city parks.
Researchers found that the arthropods that were most vulnerable to flooding were the same groups that were most sensitive to chronic stress in medians compared with parks before the storm.
“These data suggest that one result of the increasing frequency and intensity of extreme weather events will be homogenization of diversity in cities and that the direction of this simplification of urban communities may be quite predictable,” says Savage. “It’s very encouraging because it suggests that we may be able to make smart management decisions to mitigate the damaging effects of extreme weather events on urban ecosystems.”
In August of 2012, Savage began studying how diversity differed across habitats with different levels of environmental stress. Two months later, Hurricane Sandy struck Manhattan. Savage’s team of researchers began studying the post-Sandy effects in the spring of 2013.
“When the storm hit, we were in a unique position to study how these arthropod communities responded to extreme storms,” says Savage. “Testing these contrasting hypotheses was an opportunity to not only help people understand and plan for diversity changes after extreme weather events, but also to provide important data that would move the field of ecology forward.”
The research can be useful in future studies on how resilient urban ecosystems are to extreme weather events.
“Between Hurricanes Harvey, Irma, and Maria, the 2017 Atlantic hurricane season underscores this point,” says Savage. “We can now use our data from Manhattan after Super Storm Sandy to make predictions about how diversity may change in Houston after Hurricane Harvey and in the urban centers of Puerto Rico after Hurricanes Irma and Maria, among other areas affected by these storms.”

The NSF sure wastes a lot of money
It’s a government agency. That’s its job.
It is a well-known fact (or at least it should be) that there are ”disaster species” that expand and multiply when there has been some kind of more or less widespread disturbance, like a grass-fire or a hurricane or an asteroid impact. Ordinarily these species eke out a marginal existence on small-scale disturbed habitats like e. g. street medians. And yes, such disaster biota are usually (but not always) less diverse than more stable biota.
I think in all fairness we should see this from their standpoint as well. “Oh boy! All of Central Park has become disturbed habitat, Go for it guys!”
However I can tell those pioneering “researchers” in advance that it doesn’t last. Such “weedy” species can’t compete long-term with forms better adapted to more stable habitat, so in a few years time things will be back to normal. Particularly for arthropods which are well-nigh impossible to exterminate.
By the way all urban organisms tend to be a bit “weedy”, species that require really long-term stability don’t do well in cities. Dandelions, not Sequoias.
Has anyone else noticed the disappearance of both insects and birds in their area.
Yes, fewer insects.
Lots of birds.
Winter . . . . and Black Oil Sunflower seeds tend to do that.
DAMN!
I sure hope someone thought to heat all those turtle tunnels.

I know. Turtles aren’t bugs. But, bugs just might possibly sometimes use them too? NYC just needs to fund smaller but longer tunnel that will link with all the turtle tunnels down south.
Of course, that may introduce an even worse, alternate “consensus”.

“Urban insects are more resilient in extreme weather”
Urban insects? Really! Insects are tough little things, been around a lot longer than, so called, intelligent mammals such as humans. Insects can be thrust up high in to the atmosphere, freeze, fall back to earth, thaw and go about what they were doing before the interruption as if it never happened.
I agree, this study is junk!
