The ELIXIR Biodiversity Community: Understanding short- and long-term changes in biodiversity.

Biodiversity loss is now recognised as one of the major challenges for humankind to address over the next few decades. Unless major actions are taken, the sixth mass extinction will lead to catastrophic effects on the Earth's biosphere and human health and well-being. ELIXIR can help address the technical challenges of biodiversity science, through leveraging its suite of services and expertise to enable data management and analysis activities that enhance our understanding of life on Earth and facilitate biodiversity preservation and restoration.

Recommendations for connecting molecular sequence and biodiversity research infrastructures through ELIXIR.

Threats to global biodiversity are increasingly recognised by scientists and the public as a critical challenge. Molecular sequencing technologies offer means to catalogue, explore, and monitor the richness and biogeography of life on Earth. However, exploiting their full potential requires tools that connect biodiversity infrastructures and resources.

Hair cortisol measurement in older adults: Influence of demographic and physiological factors and correlation with perceived stress.

Aims: This study aimed to investigate correlation between hair cortisol levels and perceived stress scale (PSS) in addition to a range of demographic and physiological factors in a sample of older adults.

Experimental: Hair cortisol concentrations were established from 42 older adults aged between 60 and 80 years old. Age, sex, hair colour, smoking status, employment status, daytime sleeping, medication, waist to hip ratio (WHR) and PSS scores were assessed through a questionnaire.
