Richard A. Erickson, Eric E. Eager, Patrick Kocovsky, David C. Glover, Jahn L. Kallis, K. R. Long
2018, Ecological Modelling (387) 163-171
Natural resource managers and ecologists often desire an understanding of spatial dynamics such as migration, dispersion, and meta-population dynamics. Network-node models can capture these salient features. Additionally, the state-variable used with many species may be appropriately modeled as a continuous variable (e.g., length) and management activities sometimes can only target individuals of...

Variation in the vital rates of an Antarctic marine predator: the role of individual heterogeneity
J. Terrill Paterson, Jay J. Rotella, William A. Link, Robert A. Garrott
2018, Ecology (99) 2385-2396
Variation in life‐history traits such as lifespan and lifetime reproductive output is thought to arise, in part, due to among‐individual differences in the underlying probabilities of survival and reproduction. However, the stochastic nature of demographic processes can also generate considerable variation in fitness‐related traits among otherwise‐identical individuals. An improved understanding...

Sophie N. Chu, Zhaohui Aleck Wang, Meagan Gonneea Eagle, Kevin D. Kroeger, Neil K. Ganju
2018, Marine Chemistry (206) 7-18
The lateral export of carbon from coastal marshes via tidal exchange is a key component of the marsh carbon budget and coastal carbon cycles. However, the magnitude of this export has been difficult to accurately quantify due to complex tidal dynamics and seasonal cycling of carbon. In this study, we use in situ, high-frequency measurements of dissolved inorganic...
A causal partition of trait correlations: using graphical models to derive statistical models from theoretical language
James P. Cronin, Donald Schoolmaster
2018, Ecosphere (9) 1-15
Recent studies hypothesize various causes of species‐level trait covariation, namely size (e.g., metabolic theory of ecology and leaf economics spectrum), pace‐of‐life (e.g., slow‐to‐fast continuum; lifestyle continuum), evolutionary history (e.g., phylogenetic conservatism), and ecological conditions (e.g., stabilizing selection). Various methods have been used in attempts to partition trait correlation among these...

Interpretation of low‐temperature thermochronometer ages from tilted normal fault blocks
Samuel Johnstone, Joseph P. Colgan
2018, Tectonics (37) 3647-3667
Low‐temperature thermochronometry is widely used to measure the timing and rate of slip on normal faults. Rates are often derived from suites of footwall thermochronometer samples, but regression of age vs. structural depth fails to account for the trajectories of samples during fault slip. We demonstrate that in rotating fault...
