Age dating of groundwater has been used to reconstruct...
Interactive range‐limit theory (iRLT): An extension for predicting range shifts
Alexej P. K. Siren, Toni Lyn Morelli
2020, Journal of Animal Ecology (89) 940-954
A central theme of range‐limit theory (RLT) posits that abiotic factors form high‐latitude/altitude limits, whereas biotic interactions create lower limits. This hypothesis, often credited to Charles Darwin, is a pattern widely assumed to occur in nature. However, abiotic factors can impose constraints on both limits and there is scant...
