good morning. I strongly suspect that we don't really know (or agree) what geographic ranges are, and therefore, our estimates of how species' ranges are shifting in the Anthropocene are uninterpretable. I wrote something about this: doi.org/10.1111/2041... and I'll share the main findings...

Measuring the edges of species' geographic ranges
The fundamental unit of spatial ecology is a species range: the geographical area that it occupies. Species ranges are delineated by range edges (also known as boundaries or limits). Why range edg...

I am making my group read @kokkonut.bsky.social primer on continuous time models in ecology (doi.org/10.1111/2041...). Clearest presentation of Gillespie algorithm I've seen.
Comparison of deterministic and stochastic dynamics in the Lotka-Volterra predator–prey system. (a), four different limit cycles depicting deterministic predictions when starting the cycle at different densities for predators and prey, and (b–d) one run of a stochastic implementation of the same process using the Gillespie algorithm (starting at N1 = 1000, N2 = 100). The purple arrow in (a) exemplifies the problem with the Euler equation: Extrapolating from the current direction of change is prone to ‘miss the curve’. In (b–d), the first three cycles are in green, the next three in blue and the final three in red, to make it more visually clear that the system is not bound to always spiral outwards (from blue to red), the opposite can happen too (from green to blue), but the outwards movement is often observed last because it makes the population very prone to extinction. Other parameters: b = 2, B1 = 5, B2 = 1, a = 0.1, μ = 1, n = 150.
