There are a bunch of interaction models out there, when should you think about using this one?

We then applied the new model to a case study of interactions between coyote, fisher, and marten in northern New York.

We detect interactions between species that we did not detect using co-occurence models! (11/13)

What I think is really neat here is the variable ecological contexts of use - from intraguild interactions to parasite- or predator- mediated competition through to trophic cascades. (9/13).

What if you are interested in interactions between more than two species? No problem, more species, more sub models. (8/13).

Our solution was to develop a framework that explicit considers species abundance using detection/non-detection data, leveraging well established occupancy and Royle-Nichols models. (7/13).

Modelling interactions as function of occupancy may be useful when interactions are so strong that the presence of one sp. predictably results in the exclusion of another, but this is v rare.

What to do in the common scenario where interactions are mediated by abundance? (6/13)

But when is modelling co-occurrence of species useful?

Check out these two scenarios thinking about interactions between foxes and coyotes.

In which one might we get useful inference thinking about interactions as a function of occupancy?

There are a number of methods which motivated by field observations of interactions can be used to model interactions. My fav is the Rota multi-species model. The heart of this co-occurrence model is a state model for estimating the latent occupancy state of a site. (4/11)

The difficulties of scaling up local observations of interactions between species to landscape-scales are exemplified when you consider that interactions vary in their strength and direction depending on habitat, community composition, and abundance of species of interest. (3/13)

Ecologists spend alot of time trying to understand species interactions. Species interactions are key in driving species distribution and abundance patterns on both local and landscape-scales. But demonstrating the role of species interactions in ecosystems is non-trivial. (2/13)
