And when small trout were denied the shrimp, they became willing to fight bigger fish, ones they normally would have fled, reports Marco Vindas.

The Urban Garden as Crime Fighter...

The Urban Garden as Crime Fighter... | Geography | Scoop.it

Community gardens have been long-regarded as symbols of neighborhood revitalization, but could a well-tended patch of grass actually help fight crime? A recently published study by the University of Pennsylvania’s Perelman School of Medicine suggests the answer may be yes.

Researchers randomly selected two clusters of vacant lots in Philadelphia — one that was later greened and one that functioned as the control — to examine the effects of greening. The researchers found that greening the vacant lots made nearby residents feel significantly safer, and that the greened lots could be linked to reductions in certain gun crimes in the area. Police crime data showed that area assaults both with and without guns lessened after the greening. Researchers posited that the difference could be chalked up to the fact that it’s easier to hide illegal guns and illicit activity in a trash-laden lot than it is in a green space, and that the greening may have fostered a greater sense of unity within the neighborhood...

Climate Change Devastating Ocean Fisherman: ‘Sometimes We’ll Catch 5,000 Pounds Of Jellyfish’

Climate Change Devastating Ocean Fisherman: ‘Sometimes We’ll Catch 5,000 Pounds Of Jellyfish’ | Geography | Scoop.it

For many U.S. fisherman, there's no debate about climate change. In New Jersey, researchers are finding fewer and fewer northern species and more and more southern species, forcing fisherman to reevaluate what they fish for. Off the coast of Oregon, ocean acidification and hypoxia (a depletion in the ocean’s oxygen which can cause dead zones) are two of the biggest problems facing the region’s ocean ecosystems. Rising water temperatures  are causing jellyfish populations to increase, damaging the marine food chain and clogging fishermen’s nets.
