James O'Dwyer (University of Illinois Urbana-Champaign) and Sally Otto (UBC) interviewed Robert D. Holt, the Arthur R. Marshall, Jr., Chair in Ecological Studies at the University of Florida. We chatted with Bob as he recounted his journeys as a naturalist turned scholar. His interests guided him into some influential early conversations that turned into a life-long career at the interface of modelling in ecology and evolution.
On advice to students:
“Maintain some breadth in your experience”
“Read monographs...read annual reviews, because someone has synthesized 100s of papers that you don’t have to read because you get the high points."
“Start writing right away...Put everything down...even simple models can have interesting insights.”
Notable quote: “When people do write down models, they often try to make them pretty complicated from the get go. And maybe that is where you have to end up but I think there are way stations which are like step stools to understanding more complex systems from simple systems."

Most “aha” moments:
(1) Working out the mathematics of apparent competition and then realizing that a more general proof was possible based on isoclines, broadening the result to any model with similar properties (#1 Holt 1977 TPB)
(2) Recognizing that noise can lead to a higher number of individuals in a sink population than expected from the average growth rate, now known as the 'inflationary effect’ (#123 Gonzalez & Holt 2002). This idea recently contributed to understanding why SARS-CoV-2 cases were less well controlled because of the lack of coordination among jurisdictions (#356 Kortessis et al. 2020 PNAS).
(3) Stripping down the complexities of the evolution of species ranges to: when can a sink population adapt to its local environment, expanding its niche? This led to a series of papers on evolutionary rescue (#48 Gomulkiewicz and Holt 1995 Evolution) and on niche evolution in sink populations (#70, #72 Holt and Gomulkiewicz 1997a,b; #87 Gomulkiewicz and Holt 1999 TPB).
Favourite paper that you wish was better known: #59 Holt 1996 in Evolutionary Ecology, which explored the deep connections between senescence and trade-offs in selection among ages and local adaptation and trade-offs in selection across space.
