A new model by Imperial College London and University of Lausanne researchers suggests that 'good genes' can sometimes lead to population collapse when males express traits that damage females. This can result in reduced female fecundity or even death, ultimately leading to a decline in population viability.
Researchers from the University of Queensland found that humpback whales have shifted their mating behaviour, with males giving up singing and instead fighting for dominance. This change is believed to be due to the increased population size after whaling cessation, as larger groups may deter other males from approaching potential mates.
