6% to 406. Here we present an updated catalog of that marine fish fauna, including voucher photographs of 280 species recorded there in 2017 and 2020. The Statia reef-fish fauna likely is incompletely documented as it has few small, shallow, cryptobenthic species, which are a major component of the regional fauna. A lack of targeted sampling is probably the major factor explaining that deficit, although a limited range of benthic marine habitats may also be contributing.Three new species of the genus Exocelina Broun, 1886 E. brazzasp. nov., E. amabilissp. nov. and E. mimikasp. nov. are described from New Guinea. The former two species are placed into the E. ekari group, while the latter is suggested to be a member of a separate lineage, the newly introduced E. skalei group. The only other species of that group is E. skalei Shaverdo & Balke, 2014. The group is phylogenetically sister of the E. Navitoclax ekari group. All species have been collected on the southern slopes of the New Guinea central range, a region that remains mostly unsampled.Two new species of Bembidion are described from river shores in North America. One, Bembidion mimbressp. nov., from the Gila River watershed in the lands of the Mimbres culture in New Mexico and Arizona, is closely related to the widespread Bembidion levigatum. DNA sequences from several linkage groups and morphology provide evidence of the distinctiveness of B. mimbres. The second, Bembidion corgenomasp. nov., has been the subject of recent genomic and transcriptomic studies. It belongs in the Bembidion transversale subgroup, and occurs from California north to British Columbia, east to Montana and Nevada. The B. transversale subgroup as a whole is reviewed, and morphological characters that distinguish B. corgenoma from the similar and sympatric B. transversale and B. erosum are described and illustrated. DNA sequences of these three species show no consistent differences in 28S, COI, CAD, and Topoisomerase, and a coalescent species delimitation analysis reveals no notable structure within the complex. This is the first known trio of species within Bembidion for which those genes provide no clear signal of species boundaries. A neotype is designated for the one name in the group that lacks a primary type, Bembidium haplogonum Chaudoir. Chromosomes of the new species and their relatives are as is typical for Bembidion, with eleven pairs of autosomes and an XY/XX sex chromosome system.We report new faunistic records of Pimpla Fabricius, 1804 from Uruguay. The following species are reported from the country for the first time P. albomarginata Cameron, 1846, P. caerulea Brullé, 1846, P. perssoni Gauld, 1991, and P. semirufa Brullé, 1846. In addition, we propose a replacement name for Pimpla rufipes Brullé, 1846 and provide diagnosis, digital images, and an identification key for all the Pimpla species known to occur in Uruguay.Bumble bees are vital to our agro-ecological system, with approximately 250 species reported around the world in the single genus Bombus. However, the health of bumble bees is threatened by multiple factors habitat loss, climate change, pesticide use, and disease caused by pathogens and parasites. It is therefore vitally important to have a fully developed phylogeny for bumble bee species as part of our conservation efforts. The purpose of this study was to explore the phylogenetic relationships of the dominant bumble bees on the Tibetan plateau and in northern China as well as their placement and classification within the genus Bombus. The study used combined gene analysis consisting of sequence fragments from six genes, 16S rRNA, COI, EF-1α, Argk, Opsin and PEPCK, and the phylogenetic relationships of 209 Bombus species were explored. Twenty-six species, including 152 gene sequences, were collected from different regions throughout China, and 1037 gene sequences representing 183 species were obtained from GenBank or BOLD. The results suggest that the 209 analyzed species belong to fifteen subgenera and that most of the subgenera in Bombus are monophyletic, which is in accordance with conventional morphology-based classifications. The phylogenetic trees also show that nearly all subgenera easily fall into two distinct clades short-faced and long-faced. The study is the first to investigate the phylogenetic placement of Bombus turneri (Richards), Bombus opulentus Smith, Bombus pyrosoma Morawitz, Bombus longipennis Friese, Bombus minshanensis Bischoff, and Bombus lantschouensis Vogt, all of which are widely distributed throughout different regions of China. The knowledge and understanding gained from the findings can provide a molecular basis to accurately classify Bombus in China and to define strategies to conserve biodiversity and promote pollinator populations.
The aim was to identify the differences in experiences of Danish healthcare leaders in the beginnning of the coronavirus (COVID-19) pandemic and to generate knowledge for future leadership during and post crises.
The global spread of COVID-19 has affected healthcare systems worldwide and has forced healthcare leaders to face challenges few were prepared for. It is expected that the pandemic may hit in several waves within the next year and therefore healthcare leaders must be prepared for these waves.
An online survey was developed, and comparative analyses were performed.
One hundred and sixty hospital leaders were invited, and 72% completed the questionnaire. Significant differences were found within three selected characteristics 1) Management level significantly more heads of departments experienced taking complex decisions (
=0.05), being able to work in a way consistent with their beliefs and values (
=0.05), and they were less likely to experience that collaboration with other leaders was advngly.
Leadership support during a healthcare crisis like the COVID-19 pandemic should strategically focus on ward managers, leaders with no formal management education and leaders with less than two years of experience. Hospital leaders may use this knowledge to re-contextualize what is already known about targeted leadership support during healthcare crises and to act accordingly.
