Characteristics of the mosquito are described as “pretty”, colored black with an white abdomen and white bands on its legs. With warmer climates emerging, the Asian tiger mosquito is able to broaden its relocation rate. However, an Iowa State University team found the mosquito making a home in Des Moines, Lee, and Polk counties in central Iowa. The harshness of winters in states like Iowa assumed to end the reproducing of the insect. Since the 1980s, imports from Southeast Asia left traces of Aedes albopictus, the Asian tiger mosquito in southeastern states like California. The effects of climate change in Iowa has caused an unintentional import of Asian tiger mosquitoes to rise. While at Brucemore, they found a new winner, an Atlantic white cedar that now holds the title of state champion. The state champion tree is a black walnut located on the University of Iowa’s Pentacrest. The two frequently measure Eastern Iowa trees. Last week, Rouw measured Atlantic white cedars at the Brucemore estate in Cedar Rapids, where he saw University of Iowa arborist Andy Dhal. “Especially some of those that were so big and impressive and unique that after they came down, you’re looking at the contenders and there’s nothing else that comes close.” “I had so many big trees I’ve been monitoring so many years it’s almost like losing a friend,” Rouw said.
Some of the lost trees include a 92-foot-tall ponderosa pine in Cedar Rapids and a 70-foot tall butternut in Lisbon. In his 2021 update, he noticed that many trees that had been previously on the list no longer existed due to the derecho.
His findings are shared on the Big Trees of Iowa official registry for the DNR. Mark Rouw, who resides in Des Moines, has measured Iowa’s largest trees for more than 40 years. One of the leading causes of tree loss was the derecho in 2020. Climate change has caused the loss of hundreds of trees around the state. Intense temperature changes, lack of rain, and more frequently occurring storms have harmed Iowa’s tree population. As plastic production continues to grow, some researchers and environmental advocates are concerned about the increased likelihood for people to have microplastics in their bodies. Vethaak also plans to increase the number of polymers assessed alongside the number of participants, diversifying the results significantly. The team plans to increase its sample size to better inform their data and deepen their understanding of these particles. “The particles are there and are transported throughout the body.” “It is certainly reasonable to be concerned,” Vethaak said. Dick Vethaak, an ecotoxicologist professor at Vrije Universiteit Amsterdam in the Netherlands who worked on the research, told The Guardian that the study’s results are a breakthrough as it is the first indication of any particles from plastics in a person’s blood. Some of the samples showed more than one type of plastic at a time. The new research was published in the journal Environmental International and examined 22 participant’s blood samples. The researchers have found that babies and young children are the most vulnerable when it comes to chemical and particle exposure like this. Through this travel, particles can lodge themselves in a person’s organs. While the impact on one’s health if they have microplastics in their bloodstream is currently unknown, the research shows that particles of pollution can travel around the body. Of the people scientists tested, 80 percent showed trace particles of microplastics. News research found microplastic pollution in human blood for the first time. Now it will move to the House, which is considering a separate bill that allows some retailers – grocers and some others – to opt out of accepting container returns. If retailers opt out of the program, more redemption centers will be needed so consumers can return their containers and collect their 5-cent deposit. One of the main points of disagreement between the two sides is whether the increased handling fee will be enough to encourage new or expanded redemption centers to open. Retailers that continue to accept containers will continue to receive a penny per container. The bill increases the handling fee for redemption centers from 1 cent to 3 cents per container. Jason Schultz, R-Schleswig, floor manager of Senate File 2378, said it was “an attempt to save the bottle bill.” Democrats who opposed the legislation said it would do the opposite. Redemption centers would get a raise, and beverage wholesalers would continue to keep unredeemed deposits. U nder a bill that was approved Tuesday by the Iowa Senate retailers would be allowed to opt out of accepting bottle and can returns starting in 2023.
