The reality of climate change poses a significant threat to global biodiversity. As temperatures rise, the survival of individual species will ultimately depend on their ability to adapt to changes in habitat and their interactions with other species.
A new study published in the Proceedings of the National Academy of Sciences examines movement of the Eastern (Papilio glaucus) and Canadian (Papilio Canadensis) tiger swallowtail butterfly over a 32-year period within the geographic region where the two species mate, called the hybrid zone. The findings highlight the impact of changing climates and provide critical information for the protection and management of biodiversity.
Tuberculosis-causing mycobacteria use a select group of proteins known as virulence factors to transmit the disease, which infects roughly one third of the world’s population and causes 1.7 million deaths annually. Those proteins are cargo transported by molecular machinery, a microscopic gateway that promotes the survival of bacteria in the host.
A new study by researchers at the University of Notre Dame and Michigan State University, published in the Proceedings of the National Academy of Sciences, reveals that mycobacteria can sense when this molecular machine is present.
According to a new study, researchers have improved their method of tracking species by using the biological material those organisms leave behind known as environmental DNA (eDNA).
Scientists at the University of Notre Dame have found that exposure to just 10 minutes of light at night suppresses biting and manipulates flight behavior in the Anopheles gambiae mosquito, the major vector for transmission of malaria in Africa, according to new research published in the journal Parasites and Vectors.
By understanding how they respond to toxic elements, scientists can look at how environmental changes caused by agriculture and road runoff or warming temperatures and climate change could impact populations in lakes, rivers and standing bodies of water.
Jennifer Tank, Galla Professor in the Department of Biological Sciences co-authored new research published in the journal Proceedings of the National Academy of Sciences.
Jeff Schorey, a world-renowned expert with pioneering work on the role of exosomes in infectious diseases, has been studying mycobacterial disease for almost two decades.
