Abstract

On the Cover: Celebrating the 50th anniversary of Journal of Biogeography, the cover is comprised of five circles representing each of the journal’s five decades and papers in the current issue. Centre: An example of avian predation on Odonata (dragonflies and damselflies) in the tropics: a Rufous-tailed Jacamar (Galbula ruficauda) has caught a Buenos Aires Darner (Aeshnidae: Rhionaeschna bonariensis) in the REGUA wetland reserve in the Atlantic Forest (Brazil), January 2018; photograph by Erik I. Svensson; pp. 489–502. Top right: Opuntia dillenii (Ker-Gawl.) Haw. is a perennial spiny plant from the Neotropical Cactaceae family and one of the most exotic invasive cactus in the Canary Islands, where it can impact the spurge shrubland dominated by the endemic cactiform Euphorbia canariensis L.; photograph by Jairo Patiño; pp. 576–590. Top left: Metabarcoding of shallow water benthic communities, such as this one in Azohia, western Mediterranean, Spain, yields complementary synchronous biogeographic and metaphylogeographic perspectives; photograph by Xavier Turon; pp. 515–527. Bottom left: Hemerocallis middendorffii Trautv. et C.A. Mey is a perennial herb in the temperate to alpine zone of eastern Asia; photography by Kazutoshi Masuda; pp. 551–563. Bottom right: The cover of the first issue (March 1974) and initial 14 volumes of the Journal of Biogeography were graced by this circular logo; the golden text celebrates the journal’s 50th year.
