By comparing alternative measurements of horn length in the beetle Onthophagus taurus, we have investigated why scaling patterns differ between laboratories. We show that some measurements are confounded by including part of the head in the horn size measurement and consistently underestimate the allometry of horns in minor males. Our data show how linear measures that avoid confounding horn length with head size produce scaling patterns that support a positive allometry rather than a reprogramming model of horn growth. We also found horn volume was highly positively allometric this estimate of growth therefore further supports a positive allometry model.

Evolutionary rescue at different rates of environmental change is affected by trade‐offs between short‐term performance and long‐term survival Liukkonen, Martta; Kronholm, Ilkka; Ketola, Tarmo (Wiley-Blackwell, 2021)As climate change accelerates and habitats free from anthropogenic impacts diminish, populations are forced to migrate or to adapt quickly. Evolutionary rescue (ER) is a phenomenon, in which a population is able to avoid ...

Sexually selected traits evolve positive allometry when some matings occur irrespective of the trait Fromhage, Lutz; Kokko, Hanna (Wiley-Blackwell Publishing Ltd.; Society for the Study of Evolution, 2014)Positive allometry of secondary sexual traits (whereby larger individuals have disproportionally larger traits than smaller individuals) has been called one of the most pervasive and poorly understood regularities in the ...
