Herbivory changes biomass allocation but does not induce resistance among clones of an invasive plant
Zoe Becker, Paul J. Ode, Natalie West, Ian S. Pearse
2022, Arthropod-Plant Interactions (16) 297-307
Inducible responses to herbivores can be either localized or spread systemically throughout a plant. The ways in which clonal plants integrate their response to herbivores among clonal ramets is not well understood. Yet, this is important to understand the impacts that herbivores may have on clonal plants. We conducted a...
Geomorphic controls on floodplain connectivity, ecosystem services, and sensitivity to climate change: An example from the lower Missouri River
R. B. Jacobson, Kristen L. Bouska, Edward Bulliner, Garth A. Lindner, Craig Paukert
2022, Water Resources Research (58)
Floodplains of large rivers are exploited for agricultural production, industrial and municipal development, and transportation infrastructure. Recently, increased frequency of costly floods has prompted consideration of whether offsetting benefits might accrue from management of floodplains for ecosystem services. We employed a simple inundation model for 800 km of the Lower Missouri...
Land cover change effects on stormflow characteristics across broad hydroclimate representative urban watersheds in the United States
Kul Bikram Khand, Gabriel B. Senay
2022, Water (14)
Urban development alters stormflow characteristics and is associated with increasing flood risks. The long-term evaluation of stormflow characteristics that exacerbate floods, such as peak stormflow and time-to-peak stormflow at varying levels of urbanization across different hydroclimates, is limited. This study investigated the long-term (1980s to 2010s) effects of increasing urbanization...

Delaware and Landsat
U.S. Geological Survey
2022, Fact Sheet 2022-3064
Delaware’s status as the first State to ratify the U.S. Constitution is a well-known point of pride. “The First State” is among Delaware’s nicknames, alongside “the Blue Hen State,” “the Diamond State,” and “the Small Wonder,” the last of which relates to Delaware’s diminutive land area—larger only than Rhode Island. Less...

2022, Fact Sheet 2022-3061
Iowa is famous for plenty of reasons—its State Fair butter sculptures, its first-in-the-Nation presidential caucuses, and the Iowa Hawkeyes football team, whose mascot doubles as the State nickname—but “corn” might be the first word to cross the mind of a non-Iowan.Iowa consistently leads the United States in corn production and...

2022, Journal of Volcanology and Geothermal Research (430)
Hypocenter estimation at active volcanoes improves our understanding of their magmatic systems and indicates changing conditions at depth for continuously monitored volcanoes. The most active volcano in the Cascades Range, Mount St. Helens, has a multi-decadal earthquake catalog and it shows an apparent change in the depth distribution of seismicity before and after the...
