Human land-use changes represent the most important drivers of biodiversity loss, and
amphibians and reptiles represent the most threatened groups of vertebrates globally …

Studying and protecting each and every living species on Earth is a major challenge of the
21st century. Yet, most species remain unknown or unstudied, while others attract most of …

The ability to perceive and recognise a reflected mirror image as self (mirror self-recognition,
MSR) is considered a hallmark of cognition across species. Although MSR has been …

Conservation science is a rapidly developing discipline, and the knowledge base it
generates is relevant for practical applications. It is therefore crucial to monitor biases and …

Over the last 25 years, research on biodiversity has expanded dramatically, fuelled by
increasing threats to the natural world. However, the number of published studies is heavily …

Citizen science is fundamentally shifting the future of biodiversity research. But although
citizen science observations are contributing an increasingly large proportion of biodiversity …

While greater research on threatened species alone cannot ensure their protection,
understanding taxonomic bias may be helpful to address knowledge gaps in order to identify …

Taxonomic bias is pervasive in organismal research; ie, research is not proportional to
organisms' frequency in nature (1–4). Quantifying research bias is difficult, but a reasonable …

As a cultural ecosystem service, the aesthetic value of landscapes contributes to human well-
being, but studies linking biodiversity and ecosystem services generally do not account for …
