UrduA global study has uncovered a strong link between the microbes found in sewage and a country’s economic conditions. By analyzing samples from 60 countries, researchers found that the diversity of human-related microbes varies widely, influenced by factors such as export levels and social security. This study demonstrates how sewage can be a valuable tool for monitoring public health and assessing the impact of economic conditions on microbial communities worldwide.

Global patterns of Rhododendron diversity explained by island biogeography theory and habitat heterogeneity
• Global Rhododendron hotspots are mainly distributed in the Hengduan Mountains of southwestern China and the southern regions of the Himalayas.
• Rhododendron diversity patterns were most strongly explained by proxies of island biogeography theory (i.e., mountain area) and habitat heterogeneity (i.e., elevation range).
Study looks at Impact of Native American Land Use on Forests
In a new article published in the Journal of Biogeography, SUNY Geneseo geographer Associate Professor Stephen Tulowiecki and four undergraduate researchers examined the influence of Native American land use on the composition of historic forests in the Northeastern United States. The team found that Native American settlements and land use had a lesser effect on the distribution of tree species across the region when compared to climate and soil conditions.
Biologists awarded NSF grant to model evolution of Hawaiian plants
The research team will focus on 12 understudied plant groups — including Kadua, Wikstroemia and Psychotria — using new sequencing and modeling techniques to gain a broader idea of how Hawaiian plant diversity originated. The project includes conservation and educational components as well, including collecting new wild specimens for the National Tropical Botanical Garden herbarium.
