Scientists have warned decision-makers about the severe consequences of the global environmental crisis since the 1970s. Yet ecological degradation con- tinues and little has been done to address climate change. We investigated early-career conservation researchers' (ECR) perspectives on, and prioritization of, actions furthering sustainability. We...
Article
Conserving functionally diverse bird communities in European farmland is becoming critical, with no exception for regions of wine production. Management intensification combined with the loss of semi‐natural habitats in wine‐growing landscapes has led to a long‐term decline in birds of conservation concern, but also in once common insectivores and...

The global COVID-19 pandemic that we are currently facing is forcing most countries around the world to put in place social distancing and/or drastic population containment measures. A notable effect of these measures is the reduction of many urban economic activities. This decline in activities is directly linked to a reduction in several inter- and intra-urban physical flows, first and foremost among which are individual travel — all modes combined — and motorized transport of people and goods. These movements and transport are two major sources of anthropogenic noise in all spaces, both urban and rural. While we recognize the severity and serious consequences of the pandemic, we want to continue to do what we do the best: searching, testing, experimenting. In other words, we want to continue to question the world in which we live. Starting from the abnormal situation generated by the COVID-19 pandemic in territories placed in more or less strict containment, we propose to the Ecoacoustic international community to participate in a collection of urban sonic environments to document these rare urban soundscapes. Based on standardized global ecoacoustic monitoring over several weeks, we hope to achieve three scientific objectives: 1. To study in “ordinary spaces” the ecoacoustic diversity usually masked by anthropogenic noise. 2. To study the relationship between biophony and anthropophony within different levels of economic activity, as the economic activity of a territory will slowly be restored. 3. To finely characterize the relationship linking the anthropogenic noise to the level of stable economic activity of a territory.
