Image credit: Anahi Espindola & Tara Pelletier Congratulations to Entomology's Anahí Espíndola, co-author of a new research paper, “Predicting plant conservation priorities on a global scale,” published in the Proceedings of the National Academy of Sciences. Anahi co-developed a machine learning algorithm that predicts which plant species may be eligible for the IUCN Red List of Threatened Species. Researchers hope this algorithm will help prioritize conservation efforts.

This first assessment of planetary boundaries for antibiotic and pesticide resistance shows several boundaries have already been crossed. “Based on current trends in antibiotic, insecticide and herbicide resistance, we conclude that the states of all six assessed variables are beyond safe zones, with three variables surpassed regionally or globally.” Find full press release on SESYNC’s news page.

Publication: "Effect of Genetic Diagnosis on Patients with Previously Undiagnosed Disease"  Congratulations to Brett Kent on his latest publication, “The Geology and Vertebrate Paleontology of Calvert Cliffs, Maryland, USA”, published on Sept. 25th in Smithsonian Contributions to Paleobiology.
Over 100 years have passed since the last comprehensive review of fossils from Calvert Cliffs was published. This new publication updates us on the new discoveries found among the cliffs. Within this multi-authored volume, “Bretton W. Kent describes the cartilaginous fish fauna, consisting of 54 species—3 ratfishes, 39 sharks, and 12 skates and rays—a fauna rich in large predatory sharks and large neritic rays. In an addendum to Kent’s chapter, he and David J. Ward describe a new species of giant thresher shark with serrated teeth.” Read the full release here.  UMD Scientists, Heather H. Disque, Kelly A.

Climate change, transgenic corn adoption and field-evolved resistance in corn earworm. Pests aggravate the agricultural costs of climate change. Understanding climate change interaction with transgenic crops, a key insect pest management strategy, helps minimize agricultural losses. We found that increasing temperature anomaly and its interaction with high Bt acreage probably accelerated Bt resistance development in a major crop pest, corn earworm. Bt resistant corn earworms may spread further given extensive Bt adoption, and their range expansion due to climate change. We highlight the need to incorporate evolutionary processes affected by climate change into Bt resistance management programs, and the challenges posed by climate change for Bt biotechnology based insect pest management.

Building engineered structures, such as dams and dikes, has been the conventional approach to water management. Some suggest that such "gray" infrastructure make way for "green" ecosystem-based approaches. Margaret Palmer, Director of the National Socio-Environmental Synthesis Center (SESYNC) co-authored in support of managing water in a green way.
 An adult brown marmorated stink bug (Halyomorpha halys) feeding on the ripe fruits of a serviceberry tree. Image credit: Michael Raupp A new study by entomologists at the University of Maryland shows that brown marmorated stink bugs have a strong preference for ripe fruit. The study, published online June 25, 2015 in the Journal of Pest Science, reports the number of stink bugs feeding on nearly 4,000 fruit-bearing ornamental trees representing more than 200 popular varieties grown for sale at commercial nurseries. The researchers found that trees with ripe fruit attracted more than twice as many adult stink bugs compared with trees bearing immature fruit.
