📣Our line-up for our next theoretical ecology series (crossing three continents!),

It will have been 5 years since we started, and still all our seminars are fully open on Zoom (iite.info/seminar/).

There is no need to register, but you can sign up to email updates here iite.info/seminar-emai...

Come and work with us! Review of candidates will begin ~1 October with rolling consideration thereafter. If you are unable to apply early, contact the search committee chair (me) to discuss timelines.

Population Biology Modeling & Theory (PBMT) is a peer-reviewed journal reporting advances in modeling and theory within population biology. Its scope spans demography, ecology, epidemiology, evolutionary biology, population genetics, and phylogenetics. PBMT will be online soon.

We use invasion growth rates to develop the "Community Disassembly Graph". Nodes represent coexisting communities and directed edges represent transitions from one community composition to another due to extinction. We can use this graph to identify possible secondary extinctions. (4/X)

We apply recently-developed techniques from dynamical systems theory and modern coexistence theory to identify (1) WHEN and WHY secondary extinctions occur. We demonstrate that invasion growth rates (per capita growth rates of species when rare) can achieve these goals! (3/X)

Coexistence outcomes often depend on the complex interplay of species interactions. Consequently in some cases, the extinction of one species can trigger the loss of another, a process known as secondary extinction, as explained by a plaque I came across at the Bronx Zoo. (2/X)

Excited to share a new pre-print in collaboration with @sebastianschreiber.bsky.social, "Using Modern Coexistence Theory to understand community disassembly"! We set out to understand how techniques used to study coexistence can be extended to understand community disassembly. (1/X)
Using modern coexistence theory to understand community disassembly
Community disassembly examines how species extinction alters ecological communities. Sometimes, the extinction of one species can trigger the loss of others, known as secondary extinction. These secon...

Applications are provided to serial transfer models, data-based Lotka-Volterra models with mortality pulses, & spatial models of consumers with reproductive pulses. They illustrate the storage effect, unexpected extinctions, and the importance of the timing between reproductive pulses. 5/5

When the invasion graph is acyclic, coexistence occurs iff every subcommunity has at least one missing species with a positive invasion growth rate (IGR). Alternatively, if a subcommunity is permanent and all missing species have negative IGRs, there is an extinction attractor 4/5
