Interaction Assessment (INTASS) is a field and analytic methodology for constructing population dynamics models. Because data collected in generating a model for one species comprise much of the information needed for other species, a small increase in effort can result in simultaneous expressions for the dynamics of multiple species. These expressions can be used to simulate whole community responses to environmental change, including management actions. Since publication of the most recent paper in this series, the INTASS methodology has undergone a large number of developments. These include the use of conceptual models to direct field and modeling efforts and incorporation of an information theoretic approach...

In 'Simulation to evaluate response of population models to annual trends in detectability', we provide data and R code necessary to create simulation scenarios and estimate trends with different population models (Monroe et al. 2019). Literature cited: Monroe, A. P., G. T. Wann, C. L. Aldridge, and P. S. Coates. 2019. The importance of simulation assumptions when evaluating detectability in population models. Ecosphere 10(7):e02791. 10.1002/ecs2.2791, http://onlinelibrary.wiley.com/doi/10.1002/ecs2.2791/full.

Maui’s threatened Haleakalā silversword forms the foundation of a diverse high-elevation community on Haleakalā, and is an ideal species for assessing how this ecosystem is responding to climate change. The silversword’s striking appearance makes it one of Hawaiʻi’s most recognizable species, and it is one of the main attractions drawing 1-2 million tourists to Haleakalā National Park each year. The plant was once considered a conservation success, when active management led to a population recovery in the early 20th century. Unfortunately, silversword populations are now declining, and climate change – namely decreasing precipitation and increasing temperatures – is thought to be responsible. The goal of this...
