A Persisting Equivalence

open access: yesNoûs, EarlyView.
ABSTRACT In several articles, McCall and Lowe have claimed that endurantism and perdurantism are “equivalent.” From this, they conclude that there is no fact of the matter as to whether we live in an endurantist world or in a perdurantist world. In this paper, I use the notion of Morita equivalence to show in which precise sense, McCall and Lowe's ...

Attraction of nocturnal scarab beetles by unusual floral volatiles in a Banksia (Proteaceae) with functionally diverse pollinators

open access: yesPlant Biology, EarlyView.
Banksia attenuata (Proteaceae) attracts nocturnal scarab beetles with an unusual floral scent—the beetles pollinate the flower as they feed on pollen and nectar and mate on the inflorescences. Abstract Pollination by beetles has evolved multiple times in flowering plants but with relatively few plant species adapted specifically to pollination by ...
