Evaluating early-warning indicators of critical transitions in natural aquatic ecosystems
Alena Sonia Gsell, Ulrike Scharfenberger, Deniz Ozkundakci, Annika W. Walters, Lars-Anders Hansson, Annette B. G. Janssen, Peeter Noges, Philip Reid, Daniel Schindler, Ellen van Donk, Vasilis Dakos, Rita Adrian
2016, Proceedings of the National Academy of Sciences of the United States of America (113) E8089-E8095
Ecosystems can show sudden and persistent changes in state despite only incremental changes in drivers. Such critical transitions are difficult to predict, because the state of the system often shows little change before the transition. Early-warning indicators (EWIs) are hypothesized to signal the loss of system resilience and have been...
Testing geomorphology-derived rupture histories against the paleoseismic record of the southern San Andreas fault
Katherine M. Scharer, Ray J. Weldon, Sean Bemis
2016, Conference Paper, Proceedings of the 7th PATA Days, 2016
Evidence for the 340-km-long Fort Tejon earthquake of 1857 is found at each of the high-resolution paleoseismic sites on the southern San Andreas Fault. Using trenching data from these sites, we find that the assemblage of dated paleoearthquakes recurs quasi-periodically (coefficient of variation, COV, of 0.6, Biasi, 2013) and requires...
Does paleoseismology forecast the historic rates of large earthquakes on the San Andreas fault system?
Glenn Biasi, Katherine M. Scharer, Ray J. Weldon, Timothy E. Dawson
2016, Conference Paper, Proceedings of the 7th PATA Days, 2016
The 98-year open interval since the most recent ground-rupturing earthquake in the greater San Andreas boundary fault system would not be predicted by the quasi-periodic recurrence statistics from paleoseismic data. We examine whether the current hiatus could be explained by uncertainties in earthquake dating. Using seven independent paleoseismic records,...

Hanging out at the airport: Unusual upside-down perching behavior by Eurasian Jackdaws (Corvus monedula) in a human-dominated environment
Todd E. Katzner
2016, Wilson Journal of Ornithology (128) 926-930
Animals occupying human-dominated environments show the capacity for behavioral flexibility. Corvids are among the most intelligent synanthropic bird species. During a layover at Schipol Airport in Amsterdam, Netherlands, I photographically documented Eurasian Jackdaws (Corvus monedula) perching upside down from a building cornice. In contrast to other reports of hanging birds,...
Evolutionary traps as keys to understanding behavioral maladaptation
Bruce A. Robertson, Anna Chalfoun
2016, Current Opinion in Behavioral Sciences (12) 12-17
Evolutionary traps are severe cases of behavioral maladaptation that occur when, due to human activity, the cues animals use to guide their behavior become uncoupled from their fitness consequences. The result is that animals can prefer the most dangerous resources or behaviors, even when better options are available. Traps are...
Modeling the effects of tile drain placement on the hydrologic function of farmed prairie wetlands
Brett Werner, John Tracy, W. Carter Johnson, Richard A. Voldseth, Glenn R. Guntenspergen, Bruce Millett
2016, Journal of the American Water Resources Association (52) 1482-1492
The early 2000s saw large increases in agricultural tile drainage in the eastern Dakotas of North America. Agricultural practices that drain wetlands directly are sometimes limited by wetland protection programs. Little is known about the impacts of tile drainage beyond the delineated boundaries of wetlands in upland catchments that may...

Craig R. Allen, Hannah E. Birge, Shannon Bartelt-Hunt, Rebecca A. Bevans, Jessica Burnett, Barbara Cosens, Ximing Cai, Ahjond S. Garmestani, Igor Linkov, Elizabeth A. Scott, Mark D. Solomon, Daniel R. Uden
2016, Sustainability (8)
Eighty-five percent of United States citizens live in urban areas. However, research surrounding the resilience and sustainability of complex urban systems focuses largely on coastal megacities (>1 million people). Midsize cities differ from their larger counterparts due to tight urban-rural feedbacks with their immediate natural environments that result from heavy...
