A Review of Non-Invasive Sampling in Wildlife Disease and Health Research: What's New?

In the last decades, wildlife diseases and the health status of animal populations have gained increasing attention from the scientific community as part of a One Health framework. Furthermore, the need for non-invasive sampling methods with a minimal impact on wildlife has become paramount in complying with modern ethical standards and regulations, and to collect high-quality and unbiased data. We analysed the publication trends on non-invasive sampling in wildlife health and disease research and offer a comprehensive review on the different samples that can be collected non-invasively. We retrieved 272 articles spanning from 1998 to 2021, with a rapid increase in number from 2010. Thirty-nine percent of the papers were focussed on diseases, 58% on other health-related topics, and 3% on both. Stress and other physiological parameters were the most addressed research topics, followed by viruses, helminths, and bacterial infections. Terrestrial mammals accounted for 75% of all publications, and faeces were the most widely used sample. Our review of the sampling materials and collection methods highlights that, although the use of some types of samples for specific applications is now consolidated, others are perhaps still underutilised and new technologies may offer future opportunities for an even wider use of non-invasively collected samples.

Behavior of Wildlife Species in Urban Areas to Changing Conditions during COVID-19 Lockdowns: A Review.

The COVID-19 crisis remains an international health disaster with serious impacts on health and business. As countries asked, and continue to ask, their human populations to stay at home to limit the spread of coronavirus, wild animals have been spotted exploring the empty streets of some of the world's largest urban areas.E This period of unusually reduced human mobility can provide invaluable insights into human-wildlife interactions. Reduced human mobility during the pandemic reveals critical aspects of our impact on wild animal welfare, providing important guidance on how best to share space on this crowded planet. Lockdown effects have been drastic, sudden, and widespread. Countries have also responded in broadly similar ways across large parts of the world, presenting invaluable replicates of this phenomenon. This paper will highlight various adaptations and changes in behavior developed by wild animals in urban areas during the early pandemic period. They concerned the effects on wildlife and ecosystems that are related to human activities, possible interactions between humans and wildlife, and the perspectives on wildlife and ecosystem management going forward.
