Both candidates and interviewers agreed that the MMI format was reliable, fair and asked appropriate, easy-to-understand questions. In high-stakes interviews such as for specialty training in Modernising Medical Careers programmes, it is vital that all concerned have confidence in the selection process.
Human immunodeficiency virus, Neisseria gonorrhoeae/ Chlamydia trachomatis, and syphilis testing decreased with the implementation of mitigation measures for SARS-CoV-2 and did not return to 2019 levels by September 2020. However, primary and secondary syphilis diagnoses increased during mitigation measures. Sexual health services are essential during the SARS-CoV-2 pandemic.
Passive acoustic monitoring (PAM) can be a powerful tool to survey populations of soniferous species in natural settings. Using PAM allows monitoring of behaviour and activity unobtrusively to get a more accurate assessment of behavioural responses than traditional techniques. The use of PAM can also be beneficial for behaviourally cryptic species or other taxa that might be missed by more traditional sampling methods.
To quantify seasonality of reproduction in an aquatic invasive species and to assess possible interactions between both abiotic and biotic noise and acoustic ecology, we deployed multiple hydrophones to fully characterise the acoustic behaviour of round goby (Neogobius melanostomus), a highly invasive species. We also aimed to quantify levels of anthropogenic noise around the goby communities. We tested correlations of round goby calling rates with overall noise levels and the presence of boat traffic as direct tests of the hypothesised role of noise on natural acoustic behaviour of fish.
Round goby showed a clear diel patterning of calling behaviour, with the highest activity during the night and ceasing at midday; supporting the importance of acoustic—as opposed to visual—signalling for mate attraction. Calls also allowed us to pinpoint spawning areas for possible remediation. We saw no correlation between measures of background noise and calling behaviour or presence of boats and calling, suggesting that increased levels of noise have no effect on the natural calling behaviour of this species.
Passive acoustic monitoring of round goby calling behaviour is a promising technique for those interested in remediation of this highly invasive species, as it can be difficult to quantify population levels by more conventional means. The lack of noise effects we see suggests that noise from recreational boats does not disrupt signalling in this species with limited hearing range, although more investigation is needed to ascertain whether noise could be a stressor in other contexts.
Advection of teleost early life stages from nursery habitats can greatly impact year-class strength. Few studies test the effects of current on retention in freshwater fish eggs and larvae, so we used walleye (Sander vitreus) to assess current effects throughout egg and larval development and the role of substrate on egg retention. Eggs were removed from sand substrates at currents of 12 cm·s–1, but much higher speeds were required for removal from tile or stones. Larvae exhibited biphasic swimming ability, with slow swimming below 21 mm total length and rapidly increasing ability above 21 mm. These data necessitate adjusting models currently used to link water current and nursery advection in this and similar species, as the current effects were clearly substrate- and size-dependent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
