Paola Vannucchi, Jason P. Morgan, Eli Silver, Jared W. Kluesner
2016, Geochemistry, Geophysics, Geosystems (17) 1966-1974
Here we propose a new framework for forearc evolution that focuses on the potential feedbacks between subduction tectonics, sedimentation, and geomorphology that take place during an extreme event of subduction erosion. These feedbacks can lead to the creation of a “depositionary forearc,” a forearc structure that extends the...

Combined use of isotopic and hydrometric data to conceptualize ecohydrological processes in a high-elevation tropical ecosystem
Giovanny M Mosquera, Rolando Celleri, Patricio X Lazo, Kellie B Vache, Steven Perakis, Patricio Crespo
2016, Hydrological Processes (30) 2930-2947
Few high-elevation tropical catchments worldwide are gauged and even fewer are studied using combined hydrometric and isotopic data. Consequently, we lack information needed to understand processes governing rainfall-runoff dynamics and to predict their influence on downstream ecosystem functioning. To address this need, we present a combination of hydrometric and water...
Integrating biology, field logistics, and simulations to optimize parameter estimation for imperiled species
Wendy E. Lanier, Larissa L. Bailey, Erin L. Muths
2016, Ecological Modelling (335) 16-23
Conservation of imperiled species often requires knowledge of vital rates and population dynamics. However, these can be difficult to estimate for rare species and small populations. This problem is further exacerbated when individuals are not available for detection during some surveys due to limited access, delaying surveys and creating mismatches...
