Insights on COVID-19 impacts, challenges and opportunities for India's biodiversity research: From complexity to building adaptations.

The COVID-19 pandemic has impacted every sphere of human society. The paradigm shift of focus to COVID-related research and management has significantly affected various scientific domains, including biodiversity conservation. We assessed the perceptions of early-career researchers working for biodiversity conservation across India, to understand the impacts of the ongoing pandemic on their research. We administered an online questionnaire survey to 565 respondents, who identified four key areas that are affected by the pandemic: (1) research, (2) conservation (3) education, and (4) communication and networking. Respondents (89.2%) perceived that their fieldwork, followed by travel for meetings and funding were the most affected due to COVID-19 outbreak and subsequent lockdown. Nonetheless, responses on the impact varied between different professional categories and were disproportionate. Our study highlights that majority of the respondents (80%) advocate for stakeholder-driven policies and management practices as the most effective strategy to promote biodiversity conservation, in the post-COVID-19 world. To this end, as a post-pandemic response, we propose holistic solutions such as optimising research funding and collaborations, and supporting and strengthening them by citizen science and big data analytics. Our findings and recommendations will also serve as a paradigm for post-COVID-19 biodiversity policy, advocacy and implementation of the post 2020 biodiversity action plan that supports eco civilization.

Calappid and leucosiid crabs (Crustacea: Decapoda: Brachyura) from Kerala, India, with the description of a new species of Mursia Desmarest, 1823, from the Arabian Sea and redescription of M. bicristimana Alcock & Anderson, 1894.

Eleven species of calappid and leucosiid crabs were identified from by-catch landed by trawlers at four fishing ports in Kerala, India that were surveyed in 2007 and supplemented by material obtained in January 2013. Four species are reported for the first time from India, six are new records for Kerala. The status of Mursia bicristimana Alcock & Anderson, 1894, is clarified and the species redescribed. A new species of Mursia is described from the Gulf of Aden, Arabian Sea. 

Ferroelectric thin-film capacitors and piezoelectric switches for mobile communication applications.

Thin-film ferroelectric capacitors have been integrated with resistors and active functions such as ESD protection into small, miniaturized modules, which enable a board space saving of up to 80%. With the optimum materials and processes, integrated capacitors with capacitance densities of up to 100 nF/mm2 for stacked capacitors combined with breakdown voltages of 90 V have been achieved. The integration of these high-density capacitors with extremely high breakdown voltage is a major accomplishment in the world of passive components and has not yet been reported for any other passive integration technology. Furthermore, thin-film tunable capacitors based on barium strontium titanate with high tuning range and high quality factor at 1 GHz have been demonstrated. Finally, piezoelectric thin films for piezoelectric switches with high switching speed have been realized.
