- Journal of biogeography innovation awardsPublication . Dawson, Michael N; Correia, Ricardo; Li, Qin; Matthews, Thomas J.; Palmeirim, Ana FilipaABSTRACT: We are delighted to publish the first collection of papers submitted in response to the announcement of the Journal of Biogeography (JBI) Innovation Awards. These manuscripts were considered using JBI's standard editorial and peer review processes, and were additionally ranked in terms of the originality of their ideas, identification of a gap in knowledge, impact of findings and quality of preparation of the manuscript at each round of editorial review. The set published here are the top ranked among the submissions, and also hold their own among the novel, insightful, consequential and well-prepared manuscripts submitted year-round to JBI. The papers address a range of topics within biogeography's broad remit, the focal taxa represent divergent lineages of eukaryotes and other organisms with which they interact, and the research or teams span continents. We congratulate William Carvalho, Thais Vasconcelos and Frederic Windsor as the inaugural recipients of the journal of Biogeography Innovation Awards and their co-authors for sharing in this success.
- History of colonisation and updated distribution of the Monarch butterfly Danaus plexippus (Linnaeus, 1758) and its hostplants in mainland Portugal, Azores and MadeiraPublication . Palma, Luís; Vasconcelos, Sasha; Palmeirim, Ana Filipa; Cancela, JPABSTRACT: The first observations of the Monarch butterfly (Danaus plexippus) in Iberia date from 1886, although breeding records emerged almost a century later: 1960 in Spain, 1980s–1990s in Madeira and Azores, and 2003 in mainland Portugal. We reviewed the history of the colonisation of mainland and insular Portugal by the Monarch butterfly and its hostplants (Gomphocarpus fruticosus, G. physocarpus and Asclepias curassavica). We also compiled available historical and recent occurrence records as a basis for countrywide surveys of the butterfly and hostplants, to update their current distributions in Portugal. Locations for only a few of the older records represented newly rediscovered populations in the field, although recent occurrences were often confirmed. Hostplants were scarce and monarchs absent in northern and central mainland Portugal, but both were quite common in the southwest. In Madeira, hostplants were found in two locations, while monarchs were common and widespread. In the Azores, small hostplant patches were observed on four of seven surveyed islands, whereas monarchs were rare and restricted to two islands. Abandoned/semi-abandoned orange orchards represent the butterfly’s stronghold in Portugal, with the species being increasingly scarce along rivers and road verges where hostplants are declining. Hostplant persistence is unstable, with many patches removed, while others have expanded or colonised new areas. Overall, hostplants appear to be declining, with implications for the persistence of monarch butterflies in the country.
