To test this prediction Youngsteadt went to 20 sites where historical specimens were collected from 1970 to 1997
Sure enough scale abundance had increased at 16 of the 20 sites Youngsteadt says. Overall we found a total of about five times more scale insects in 2013 than on the historical specimens from the same locations.

The researchers focused specifically on the abundance of gloomy scales on red maple (Acer rubrum) trees at 26 sites in Raleigh North carolina.
So Dale collected gloomy scales at each site he was monitoring and dissected them to see how many young they were about to produce.
At the coolest sites--18.26 degrees Celsius (64.87 Fahrenheit)--the females were producing approximately 20 young Dale says.
At the warmest sites--20.12 degrees Celsius (68.22 Fahrenheit)--the females were producing around 60 young.
Populations at the warmest sites were over 200 times more abundant than those at the coolest sites.
Remote recorders were deployed at specific sites and the results were compared against observations from standard human field surveys of the same sites.

Trigona hyalinata spies that detect food sources marked by Trigona spinipes foragers will often displace T. spinipes from desirable sites in the wild
But Lichtenberg found in a controlled field study that the eavesdropping species will avoid desirable sources of food that have been visited frequently by T. spinipes (communicated by the larger number of pheromone markings at the site) to avoid being attacked.
The eavesdroppers could take over the highly visited sites by recruiting more of their nestmates or battling with T. spinipes bees

The addresses then were overlaid on maps with the locations of agricultural chemical application sites based on the pesticide-use reports to determine residential proximity.
The researchers found that during the study period approximately one-third of CHARGE Study participants lived in close proximity--within 1. 25 to 1. 75 kilometers--of commercial pesticide application sites.
Some associations were greater among mothers living closer to application sites and lower as residential proximity to the application sites decreased the researchers found.

They also set up pollen collectors at 34 sites and analyzed the concentration of ragweed pollen grains collected at each location.
They found that the amount of ragweed pollen in the air at a collection site was determined both by the abundance of ragweed plants within 10 meters (33 feet) of the collector and by the number of vacant lots within 1 kilometer (0. 62 miles) of the site.

and placed them at each site so they could watch how quickly they dissolved. To determine whether local growing conditions were poor for the grasses they planted healthy grass in each site
and then protected it from all herbivores including the crabs. To assess whether any site had too much nitrogen they took leaves of the grasses at each site back to the lab ground them up
and analyzed their chemistry. In the second week in July they measured herbivory at each site by walking a 20-meter line at each site
and then stopping every two meters to measure signs of crab damage on 100 cordgrass stalks.
They even measured how hard the marsh soil was at each site. When fall came they analyzed all the data.
The number crunching revealed that differences in herbivory at each site explained 73 percent of the variation in die off from at each site.

That's why the team chose to look at ESR project sites. We have this problem with nonnative plants coming in changing the fire cycle

Arkle and colleagues examined 101 sites that burned once between 1990 and 2003. To select their sites they compiled a database of fires
and ESR projects from which they randomly chose a set of project sites with a gradient of precipitation and annual temperatures but similar soil types.
Treated plots were not much more likely to be used by sage grouse than the burned and untreated on average
Arkle and his colleagues found little sagebrush cover at burned sites whether treated or not.
because some sites burned 20 years ago and still haven't recovered said Arkle. We did not see a trend of increasing sagebrush cover with time
if just 2. 5%of the land is developed within five kilometers of a site the birds will be half as likely to use it.
The outlier ESR sites preferred by sage grouse had healthier sagebrush and shared common climate and post-treatment weather conditions.

and far away from supplementary feeding sites located in the forest for ungulates such as deer and wild boar researchers found that those nests in the vicinity of feeding sites were depredated twice more.
This predation hotspot effect extends far away from the feeding site itself: in a radius of 1-km the probability of nest survival is lowered.
These sites attract not only deer and wild boar--the boar is also a nest predator--but also corvids rodents bears and other species of nest predators
