Extinction debt (Landscape ecology 🏞️)
In ecology, extinction debt is the future extinction of species due to events in the past. The phrases dead clade walking and survival without recovery express the same idea. Extinction debt occurs because of time delays between impacts on a species, such as destruction of habitat, and the species' ultimate disappearance. For instance, lo...

How much does landform position matter for vegetation dynamics across Calgary?
I explored how ΔNDVI (2025-2024) varies across geomorphon classes (summit, ridge, slope, hollow, valley, etc.) using a large spatial dataset (~194k observations).
A few key points from the analysis:
• Non-parametric Kruskal–Wallis test shows statistically significant differences between geomorphons
• However, the effect size is moderate (ε² ≈ 0.04)
• Distributions strongly overlap — landform position matters, but it is not a deterministic driver
• Median ΔNDVI tends to be higher in lower landscape positions (hollows, footslopes, valleys), consistent with moisture and accumulation controls#EnvironmentalData #RemoteSensing #NDVI #LandscapeEcology #Geomorphology #DataAnalysis #RStats

Biogeography (Earth sciences 🌍)
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. Phytogeography is the branch of biogeography that stu...
