A Gender-Selective Harvesting Strategy: Weak Allee Effects and a Non-hyperbolic Extinction Boundary
Acta Biotheor. 2023 Mar 18;71(2):11. doi: 10.1007/s10441-023-09462-w.ABSTRACTRecently a gender-selective harvesting strategy has been proposed for possible control of aquatic invasive species, wherein females of the invasive species are harvested, whilst stocking the males (abbreviated as FHMS strategy) (Lyu et al. in Nat Resour Model 33(2):e12252, 2020). We consider the FHMS strategy with a weak Allee effect, and show that its extinction boundary need not be hyperbolic. To the best of our knowledge, this is the first example of a non-hyperbolic extinction boundary in two-compartment mating models structured by sex. The mo...

Random with Respect to Fitness or External Selection? An Important but Often Overlooked Distinction
Acta Biotheor. 2023 Mar 18;71(2):12. doi: 10.1007/s10441-023-09464-8.ABSTRACTMutations are often described as being "random with respect to fitness." Here we show that the experiments used to establish randomness with respect to fitness are only capable of showing that mutations are random with respect to current external selection. Current debates about whether or not mutations are directed may be at least partially resolved by making use of this distinction. Additionally, this distinction has important mathematical, experimental, and inferential implications.PMID:36933070 | DOI:10.1007/s10441-023-09464-8 (Source: Acta Biotheoretica)
