Alan Kasprak, Joel B. Sankey, Daniel D. Buscombe, Joshua Caster, Amy E. East, Paul E. Grams
2018, Progress in Physical Geography: Earth and Environment (42) 739-764
In river valleys, sediment moves between active river channels, near-channel deposits including bars and floodplains, and upland environments such as terraces and aeolian dunefields. Sediment availability is a prerequisite for the sustained transfer of material between these areas, and for the eco-geomorphic functioning of river networks in general. However, the...

Dynamic occupancy modeling of temperate marine fish in area-based closures
Jay Calvert, Chris McGonigle, Suresh Sethi, Bradley Harris, Rory Quinn, Jon Grabowski
2018, Ecology and Evolution (8) 10192-10205
Species distribution models (SDMs) are commonly used to model the spatial structure of species in the marine environment, however, most fail to account for detectability of the target species. This can result in underestimates of occupancy, where nondetection is conflated with absence. The site occupancy model (SOM) overcomes this failure...

Geena F. Littel, Amanda M. Thomas, Annemarie S. Baltay Sundstrom
2018, Geophysical Research Letters (45) 9579-9587
Tectonic tremor can be used to constrain seismic‐wave attenuation for use in ground‐motion prediction equations (GMPEs) in regions where moderately sized earthquakes occur infrequently. Here we quantify seismic‐wave attenuation by inverting tremor ground motion amplitudes in different frequency bands of interest, to determine frequency dependence of and spatial variations in...
The ecology of movement and behaviour: a saturated tripartite network for describing animal contacts
Kezia R. Manlove, Christina M. Aiello, Pratha Sah, Bree Cummins, Peter J. Hudson, Paul C. Cross
2018, Proceedings of the Royal Society B: Biological Sciences (285)
Ecologists regularly use animal contact networks to describe interactions underlying pathogen transmission, gene flow, and information transfer. However, empirical descriptions of contact often overlook some features of individual movement, and decisions about what kind of network to use in a particular setting are commonly ad hoc. Here, we relate individual movement...

2018, Journal of Wildlife Management (83) 109-120
Conserving tidal-marsh bird communities requires strategies to address continuing pressures from human development to the effects of increasing rates of sea-level rise. Knowing tidal-marsh bird distributions and population sizes are important for developing these strategies. In the Northeast United States, where estimates of sea-level rise are 3 times higher than...
Patch age since disturbance drives patch dynamics for flycatchers breeding in both reservoir and riverine habitat
Tad C Theimer, Mark K. Sogge, Eben H. Paxton
2018, Ecosphere (9)
Species dependent upon early-successional landscapes often occupy patches at different stages of recovery after disturbance. The demographic processes that drive patch dynamics in these systems have rarely been described but are important for developing effective conservation and management plans, especially when humans have modified the timing and intensity of disturbances...

The digital elevation model documented here provides a tool for calibrating tsunami models to effects of the 1945 Makran tsunami that were observed in Karachi Harbour. The DEM bathymetry is derived from soundings made mainly during the first 8 years post-tsunami. While deficient in its portrayal of...
A bioenergetics evaluation of temperature‐dependent selection for the spawning phenology by Snake River fall Chinook salmon
John M. Plumb
2018, Ecology and Evolution (62) 351-354
High water temperatures can increase the energetic cost for salmon to migrate and spawn, which can be important for Snake River fall‐run Chinook salmon because they migrate great distances (>500 km) at a time when river temperatures (18–24°C) can be above their optimum temperatures (16.5°C). Average river temperatures and random combinations...

Incorporating teleseismic tomography data into models of upper mantle slab geometry
Daniel E. Portner, Gavin P. Hayes
2018, Geophysical Journal International (215) 325-332
Earthquake-based models of slab geometry are limited by the distribution of earthquakes within a subducting slab, which is often heterogeneous. The fast seismic velocity signature of slabs in tomography studies is independent of the distribution of earthquakes within the slab, providing a critical constraint on slab geometry when earthquakes are...
