2017, Neotropical Ichthyology (15) 1-12
Populations show spatial-temporal fluctuations in abundance, partly due to random processes and partly due to self-regulatory processes. We evaluated the effects of various external factors on the population numerical abundance of curimba Prochilodus lineatus in the upper Paraná River floodplain, Brazil, over a 19-year period. Panel data analysis was applied to examine...
Role of a naturally varying flow regime in Everglades restoration
Judson Harvey, Paul R. Wetzel, Thomas E. Lodge, Victor C. Engel, Michael S. Ross
2017, Restoration Ecology (25) S27-S38
The Everglades is a low-gradient floodplain predominantly on organic soil that undergoes seasonally pulsing sheetflow through a network of deepwater sloughs separated by slightly higher elevation ridges. The seasonally pulsing flow permitted the coexistence of ridge and slough vegetation, including the persistence of productive, well-connected sloughs that seasonally concentrated prey...

Seasonality of change: Summer warming rates do not fully represent effects of climate change on lake temperatures
Luke Winslow, Jordan S. Read, Gretchen J. A. Hansen, Kevin C. Rose, Dale M. Robertson
2017, Limnology and Oceanography (62) 2168-2178
Responses in lake temperatures to climate warming have primarily been characterized using seasonal metrics of surface-water temperatures such as summertime or stratified period average temperatures. However, climate warming may not affect water temperatures equally across seasons or depths. We analyzed a long-term dataset (1981–2015) of biweekly water temperature data in...

Earthquake-induced landslide (EQIL) inventories are essential tools to extend our knowledge of the relationship between earthquakes and the landslides they can trigger. Regrettably, such inventories are difficult to generate and therefore scarce, and the available ones differ in terms of their quality and level of completeness. Moreover, access to existing...
Continuously amplified warming in the Alaskan Arctic: Implications for estimating global warming hiatus
Kang Wang, Tingjun Zhang, Xiangdong Zhang, Gary D. Clow, Elchin E. Jafarov, Irina Overeem, Vladimir Romanovsky, Xiaoqing Peng, Bin Cao
2017, Geophysical Research Letters (44) 9029-9038
Historically, in situ measurements have been notoriously sparse over the Arctic. As a consequence, the existing gridded data of surface air temperature (SAT) may have large biases in estimating the warming trend in this region. Using data from an expanded monitoring network with 31 stations in the Alaskan Arctic, we...
Causes of distal volcano-tectonic seismicity inferred from hydrothermal modeling
Cecile A. Coulon, Paul A. Hsieh, Randall A. White, Jacob B. Lowenstern, Steven E. Ingebritsen
2017, Journal of Volcanology and Geothermal Research (345) 98-108
Distal volcano-tectonic (dVT) seismicity typically precedes eruption at long-dormant volcanoes by days to years. Precursory dVT seismicity may reflect magma-induced fluid-pressure pulses that intersect critically stressed faults. We explored this hypothesis using an open-source magmatic-hydrothermal code that simulates multiphase fluid and heat transport over the temperature range 0 to 1200 °C....
