John B. S. Haldane (1892-1964), noted British geneticist, physiologist, and popularizer of science, established new paths of research in population genetics and evolution. Emphasizing the immensity of the Milky Way in the night sky and the fact that there were 400,000 species of beetles but only 8,000 species of mammals, he is reported to have said, “If one could conclude as to the nature of th...

In evolutionary biologist circles, J.B.S. Haldane’s quip to a theologian that from his studies, he has learned God has an ‘‘inordinate fondness of beetles’’, is a perennial favorite to quote, misquote and modify, even though it’s unclear whether the encounter ever actually happened. The point was simply that, but for the vagaries of evolution, beetles were among the most diverse groups of speci...

Cut flower gifting preferences are relatively unexplored in Germany. This study proposes a model that investigates the impact of attitudinal, experiential, and socio-demographic factors on cut German consumers. For this purpose, an online survey with representative sample 978 residents was conducted. Partial least squares structural equation modelling shows active passive engagement plants natu...

Why do some groups of organisms, like beetles, have so many species, and others, like the tuataras, so few? This classic question in evolutionary biology has a deep history and has been studied using both fossils and phylogenetic trees. Phylogeny-based studies have focused on tree balance, which compares the number of species across clades of the same age in the tree. These studies have suggest...
