New EMRRP Publication: Aboveground wetland vegetation growth responses to simulated sediment (April 27, 2023)
River sediment diversions are large-scale restoration techniques intended to rehabilitate Louisiana's degraded coastal wetlands by mimicking historic crevasse splays, thereby stimulating land building and vegetation growth. In this research, monospecific sods of three foundational marsh species (Spartina patens, Spartina alterniflora, Typha latifolia) were studied with a range of anticipated sediment diversion scenarios in a mesocosm setting.

New EMRRP Publication: Simple statistical models can be sufficient for testing hypotheses with population time-series data (September 27, 2022)
Time-series data offer wide-ranging opportunities to test hypotheses about the physical and biological factors that influence species abundances. Although sophisticated models have been developed and applied to analyze abundance time series, they require information about species detectability that is often unavailable. We propose that in many cases, simpler models are adequate for testing hypotheses.
