How many bird and mammal extinctions has recent conservation action prevented?

Aichi Target 12 of the Convention on Biological Diversity (CBD) aims to ‘prevent extinctions of known threatened species’. To measure its success, we used a Delphi expert elicitation method to estimate the number of bird and mammal species whose extinctions were prevented by conservation action in 1993 - 2020 (the lifetime of the CBD) and 2010 - 2020 (the timing of Aichi Target 12). We found that conservation prevented 21–32 bird and 7–16 mammal extinctions since 1993, and 9–18 bird and 2–7 mammal extinctions since 2010. Many remain highly threatened, and may still become extinct in the near future. Nonetheless, given that ten bird and five mammal species did go extinct (or are strongly suspected to) since 1993, extinction rates would have been 2.9–4.2 times greater without conservation action. While policy commitments have fostered significant conservation achievements, future biodiversity action needs to be scaled up to avert additional extinctions

How many bird and mammal extinctions has recent conservation action prevented?

Aichi Target 12 of the Convention on Biological Diversity (CBD) contains the aim to ‘prevent extinctions of known threatened species’. To measure the degree to which this was achieved, we used expert elicitation to estimate the number of bird and mammal species whose extinctions were prevented by conservation action in 1993–2020 (the lifetime of the CBD) and 2010–2020 (the timing of Aichi Target 12). We found that conservation action prevented 21–32 bird and 7–16 mammal extinctions since 1993, and 9–18 bird and two to seven mammal extinctions since 2010. Many remain highly threatened and may still become extinct. Considering that 10 bird and five mammal species did go extinct (or are strongly suspected to) since 1993, extinction rates would have been 2.9–4.2 times greater without conservation action. While policy commitments have fostered significant conservation achievements, future biodiversity action needs to be scaled up to avert additional extinctions.https://wileyonlinelibrary.com/journal/conlMammal Research Institut

Incursion of Schmallenberg virus into Great Britain in 2011 and emergence of variant sequences in 2016

Schmallenberg virus (SBV) is a vector-borne orthobunyavirus in the family Bunyaviridae, first identified in Germany before rapidly spreading throughout Europe. To investigate the events surrounding the incursion of this virus into Great Britain (GB) and its subsequent spread, archived sheep serum samples from an unrelated field survey in 2011 were analysed for the presence of SBV specific antibodies, to determine the earliest date of seroconversion. This serological study, along with analysis of the spatial spread of the sources of samples submitted for SBV analysis after January 2012, suggests that SBV entered GB on more than one occasion and in more than one location. Phylogenetic analysis of SBV sequences from 2012 ovine samples, from a variety of counties and dates, demonstrated a non-linear evolution of the virus, i.e. there was no distinct clustering between host species, geographical locations or during the outbreak. This also supports the notion of multiple viruses entering GB, rather than a single virus incursion. Premature termination signals were present in several non-structural putative protein sequences. One SBV sequence exhibited large deletions in the M segment of the genome. After the first outbreak in 2011–2012, interest in SBV in GB waned and continuous surveillance was not upheld. The re-emergence of SBV in 2016 has raised renewed concern and ended speculation that SBV might have been eradicated permanently from GB. When SBV sequences from 2012 were compared with those from the re-emergence in 2016–2017, a second distinct clade of SBV was identified that separates recent strains from those observed during the first outbreak

Impact of COVID-19 Restriction on Weight, Physical Activity, Diet and Psychological Distress on People with PCOS

Background: People with polycystic ovary syndrome (PCOS) have higher weight gain and psychological distress compared to those without PCOS. While COVID-19 restrictions led to population level adverse changes in lifestyle, weight gain and psychological distress, their impact on people with PCOS is unclear. The aim of this study was to investigate the impact the 2020 COVID-19 restrictions had on weight, physical activity, diet and psychological distress for Australians with PCOS. Methods: Australian reproductive-aged women participated in an online survey with assessment of weight, physical activity, diet and psychological distress. Multivariable logistic and linear regression were used to examine associations between PCOS and residential location with health outcomes. Results: On adjusted analysis, those with PCOS gained more weight (2.9%; 95% CI; 0.027–3.020; p = 0.046), were less likely to meet physical activity recommendations (OR 0.50; 95% CI; 0.32–0.79; p = 0.003) and had higher sugar-sweetened beverage intake (OR 1.74; 95% CI 1.10–2.75; p = 0.019) but no differences in psychological distress compared to women without PCOS. Conclusions: People with PCOS were more adversely affected by COVID-19 restrictions, which may worsen their clinical features and disease burden. Additional health care support may be necessary to assist people with PCOS to meet dietary and physical activity recommendations.Margaret McGowan, Siew Lim, Sharleen L. O, Reilly, Cheryce L.
