- The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

- Among the nine National Parks of Nepal, Sagarmatha National Park (SNP), established in 1976, and declared an UNESCO World Heritage Site in 1979, is one of the most attractive parks of the world-with the existence spectacular mountain ranges, among them, the Mt. Everest, Lhotse, Cho Oyu, Tamserku, Nuptse, Amadamlam and Pumori, glacial valleys, and rich biodiversity of the Himalayan ecological Zone in the Khumbhu region has become an obvious choice for tourists, trekkers and mountaineers from around the world. The tourists that visit this area have contributed signifi cantly towards improving the livelihood opportunities, but at the same time have put pressure on the environmental as well as sociocultural aspects of the people of the host area. The Sagarmatha region has spectacular features including mountain peaks, glaciers and lakes, snow fed rivers and natural streams, scenic tourist destinations, valuable fl ora and fauna, agricultural and pastoral economy, unique cultural tradition, and trends etc. All these features are under pressure due to growing human activities and their intervention which ultimately brings change in the climatic pattern of the region. Therefore, concrete efforts to balance the natural ecosystem and avoiding environmental and cultural damage are necessary, for maintaining a long-lasting image of this region.

- BackgroundThe magnitude of protection conferred following recovery from COVID-19 or by vaccine administration, and the duration of protective immunity developed, remains ambiguous. MethodsWe investigated the factors associated with anti-SARS-CoV-2 S1 IgG decay in 519 individuals who recovered from COVID-19 illness or received COVID-19 vaccination with two commercial vaccines, viz., an adenoviral vector-based (AZD1222) and a whole-virion-based inactivated (BBV152) vaccine in Chennai, India from March to December 2021. Blood samples collected during regular follow-up post-infection/-vaccination were examined for anti-SARS-CoV-2 S1 IgG by a commercial automated chemiluminescent immunoassay (CLIA). ResultsAge and underlying comorbidities were the two variables that were independently associated with the development of a breakthrough infection. Individuals who were >60 years of age with underlying comorbid conditions (viz., hypertension, diabetes mellitus and cardiovascular disease) had a ~15 times and ~10 times greater odds for developing a breakthrough infection and hospitalization, respectively. The time elapsed since the first booster dose was associated with attrition in anti-SARS-CoV-2 IgG, where each month passed was associated with an ebb in the anti-SARS-CoV-2 IgG antibody levels by a coefficient of -6 units. ConclusionsOur findings advocate that the elderly with underlying comorbidities be administered with appropriate number of booster doses with AZD1222 and BBV152 against COVID-19.
