Chvalaea australis sp. nov. is described and illustrated, representing the first species of Chvalaea Papp & Földvári, 2002 from the Australasian Region. A discussion of the geographic distribution and the possible relationship among the species of the genus is provided.
To understand what makes some species successful invaders, it is critical to quantify performance differences between native and introduced regions, and among populations occupying a broad range of environmental conditions within each region. However, these data are not available even for the world’s most notorious invasive species. Here we introduce the Global Garlic Mustard Field Survey, a coordinated distributed field survey to collect performance data and germplasm from a single invasive species: garlic mustard (Alliaria petiolata) across its entire distribution using minimal resources. We chose this species for its ecological impacts, prominence in ecological studies of invasion success, simple life history, and several genetic and life history attributes that make it amenable to experimental study. We developed a standardised field survey protocol to estimate population size (area) and density, age structure, plant size and fecundity, as well as damage by herbivores and pathogens in each population, and to collect representative seed samples. Across four years and with contributions from 164 academic and non-academic participants from 16 countries in North America and Europe thus far, we have collected 45,788 measurements and counts of 137,811 plants from 383 populations and seeds from over 5,000 plants. All field data and seed resources will be curated for release to the scientific community. Our goal is to establish A. petiolata as a model species for plant invasion biology and to encourage large collaborative studies of other invasive species.
The species group effusus of the genus Pyrops Spinola, 1839 is reviewed and the nomenclatural history of the genus Pyrops is briefly summarized. One new species from eastern Borneo, Pyrops synavei sp. nov., is described. P. gunjii (Satô & Nagai, 1994) stat. nov. is proposed as a valid species instead of a subspecies of P. whiteheadi (Distant, 1889). P. maquilinganus (Baker, 1925) is removed from the effusus group and placed back into the candelaria group. P. cyanirostris (Guérin-Méneville, 1845) is removed from the group and not attributed to any of the currently defined species groups. An illustrated key to the species of the group with the addition of P. intricatus (Walker, 1857) and a distribution map are given. The effusus group is restricted to Borneo and adjacent Laut Island and presently contains 4 species: P. effusus (Distant, 1891), P. gunjii (Satô & Nagai, 1994) stat.nov., P. synavei sp. nov. and P. whiteheadi (Distant, 1889). Trophobiosis observations with the gecko Gehyra mutilata (Wiegmann, 1835) (Reptilia: Squamata: Gekkonidae) and two species of cockroaches (Insecta: Blattodea), one Dorylaea sp. and an unidentified species of Pseudophyllodromiinae, are reported and illustrated for P. whiteheadi; observation with a cockroach, Dorylaea sp., is reported for P. intricatus.
Datua brevirostris Lallemand, 1959 is transferred to the genus Egregia Chew Kea Foo, Porion & Audibert, 2011 in the Aphaeninae and the new combination Egregia brevirostris (Lallemand, 1959)
comb. nov. is proposed. Egregia marpessa Chew Kea Foo, Porion & Audibert, 2011, the type-species of the genus Egregia, is synonymized with Egregia brevirostris (Lallemand, 1959). A second species, Egregia laprincesse sp. nov. is described from Sumatra, extending the distribution of the genus hitherto recorded only from Borneo. Distribution maps and an identification key are provided. The male genitalia of E. brevirostris are illustrated and described. The genus Datua Schmidt, 1911 now contains a single species, D. bisinuata Schmidt, 1911.
In den Bürgerwissenschaften, auch bekannt unter dem englischen Begriff Citizen Science, existiert eine Vielzahl an Forschungsansätzen und Methoden. Während diese in vielen wissenschaftlichen Disziplinen gut etabliert sind, finden sich augenscheinlich relativ wenige davon in der medizinischen und Gesundheitsforschung. Allerdings zeigt ein Blick in die Praxis, dass bürgerwissenschaftliche Ansätze in der Medizin und Gesundheitsforschung durchaus praktiziert werden, jedoch häufig unter anderen Namen. Der Artikel bietet aus interdisziplinärer Perspektive einen (selektiven) Überblick über Begriffe, reflektiert diese und die dahinterstehenden Methoden und diskutiert sie vergleichend. Im Fokus steht dabei der Grad der Beteiligung der Bürger*innen bzw. Patient*innen an wissenschaftlicher Forschung.
In seinem unlängst erschienenen Buch „Citizen Science“ untersucht der Wissenschaftstheoretiker Peter Finke die Rolle von Laiinnen und Laien für die Wissenschaft. Sein Anliegen ist es, ihre Bedeutung für den Erkenntnisfortschritt wie auch für ein praxisbezogenes bürgerschaftliches Engagement darzulegen. Aus zahlreichen Blickwinkeln variiert Finke den Grundgedanken einer Kontinuität des Handelns von Laiinnen und Laien zu dem von Fachwissenschaftlerinnen und Fachwissenschaftlern, die durch die institutionalisierten Erscheinungsformen der Wissenschaft verschleiert wird. Demgegenüber sollen im vorliegenden Beitrag Aspekte der Diskontinuität hervorgehoben werden, die es zu berücksichtigen gilt, gerade wenn man von der Wichtigkeit einer Etablierung und Förderung von „Citizen Science“ überzeugt ist.
To improve data availability and exchange in the area of the WAP complex, West Africa’s largest continuous area of reserves, we set up a citizen science project on the iNaturalist platform, allowing contribution of observations, ideally documented by photographs and/or sounds. Along with the project we created a number of online field guides for the local flora. Within only two months, 852 observations of 312 species have been assembled. We expect this dataset to further grow in the future and complement existing data sets from scientific collections and surveys.
