Subsurface water piping prevents meromixis in a deep volcanic crater lake (Dominica, West Indies)
Bryan M. Maitland, Brian O’Malley, Donald J. Stewart
2019, Hydrobiologia (839) 119-130
Boeri Lake—a small (3.6 ha) but deep (39.6 m) crater lake on Morne Micotrin in Dominica, West Indies—presents a limnological enigma; it exhibits strong morphometric and circumstantial evidence for meromixis, yet it is not stratified. We tested the hypothesis that water seepage from Boeri Lake overcomes morphometric drivers of stratification...

Facilitating adaptation to climate change while restoring a montane plant community
Christina Leopold, Steve C. Hess
2019, PLoS ONE (14)
Montane plant communities throughout the world have responded to changes in temperature regimes by shifting ranges upward in elevation, and made downslope movements to track shifts in climatic water balance. Organisms that cannot disperse or adapt biologically to projected climate scenarios in situ may decrease in distributional range and abundance...

Alexander L. Handwerger, Eric J. Fielding, Mong-Han Huang, Georgina L. Bennett, Cunren Liang, William H. Schulz
2019, Journal of Geophysical Research: Earth Surface (24) 1782-1797
Episodically to continuously active slow-moving landslides are driven by precipitation. Climate change, which is altering both the frequency and magnitude of precipitation world21 wide, is therefore predicted to have a major impact on landslides. Here we examine the behavior of hundreds of slow-moving landslides in northern California in response to large...

Ryan D. Carle, Jonathan J. Felis, Rodrigo Vega, Jessie Beck, Josh Adams, Veronica Lopez, Peter J. Hodum, Andres Gonzalez, Valentina Colodro, Tiare Varela
2019, The Condor (121)
Understanding susceptibility of seabirds to fisheries bycatch requires quantifying overlap of seabird at-sea habitat with fisheries’ distribution and effort. Pink-footed Shearwaters (Ardenna creatopus) are vulnerable seabirds that breed only in Chile. Recently, high rates of Pink-footed Shearwater bycatch (i.e. >1,500 observed mortalities 2015–2017) were documented by observers in central Chilean...

Response of water chemistry and young-of-year brook trout to channel and watershed liming in streams showing lagging recovery from acidic deposition
Daniel C Josephson, Gregory B. Lawrence, Scott D. George, Jason Siemion, Barry P. Baldigo, Clifford E. Kraft
2019, Water, Air, & Soil Pollution (230)
Reductions in sulfur emissions have initiated chemical recovery of surface waters impacted by acidic deposition in the Adirondack region of New York State. However, acidified streams remain common in the region, which limits recovery of brook trout (Salvelinus fontinalis) populations. To investigate liming as a method to accelerate recovery of...

Kubelka et al. (Report, 9 November 2018, p. 680-683) claim that climate change has disrupted patterns of nest predation in shorebirds. They report that predation rates have increased since the 1950s, especially in the Arctic. We describe methodological problems with their analyses and argue that there is no solid statistical...
