The InsectAI COST action will support insect monitoring and conservation at the national and continental scale in order to understand and counteract widespread insect declines. The Action will bring together a critical mass of researchers and stakeholders in image-based insect AI technologies to direct and drive the research agenda, build research...

Common altmetrics indices are limited and biased in the social media that they cover. In this Perspective, we highlight how and why altmetrics should broaden its scope to provide more reliable metrics for scientific content and communication.

Biological invasions are a major threat to biodiversity, ecosystem functioning and nature's contributions to people worldwide. However, the effectiveness of invasive alien species (IAS) management measures and the progress toward achieving biodiversity targets remain uncertain due to limited and nonuniform data availability. Management success is u...

The expansion of human settlements over the past few centuries is responsible for an unprecedented number of invasive species introductions globally. An important component of biological invasion management is understanding how introduction history and postintroduction processes have jointly shaped present‐day distributions and patterns of populati...

Citizen Science (CS) or community science significantly contributes to the study and management of biological invasions. Public participation in research and management boosts awareness, engagement, scientific literacy and can reduce conflict in invasive species management. Technological developments such as social media, internet scraping, eDNA, a...

I am one of the collaborators. I have provided the data for DR Congo.

The vast volume of unstructured textual data, such as that found in research papers, news outlets, and technical reports, holds largely untapped potential for ecological research. However, the labour-intensive nature of manually processing such data presents a considerable challenge. In this work, we explore the application of three state-of-the-ar...

In the face of the global biodiversity crisis, collecting comprehensive data and making the best use of existing data are becoming increasingly important to understand patterns and drivers of environmental and biological phenomena at different scales. Here we address the concept of secondary data, which refers to additional information unintentiona...

Dialects are a specific form of geographic variation of birdsong with relatively sharp boundaries between distinct song characteristics, which provide opportunities for focused studies of processes underlying the emergence of spatial patterns in vocalization. Several songbird species that exhibit dialects became models for such research, and for so...

Tissue samples are frequently collected to study various aspects of avian biology, but in many cases these samples are not used in their entirety and are stored by the collector. The already collected samples provide a largely overlooked opportunity because they can be used by different researchers in different biological fields. Broad reuse of sam...

Abstract Invasive alien species are a major threat to biodiversity and human activities, providing a strong incentive to understand the processes by which alien invasion occurs. While it is important to understand the determinants of success at each of several invasion stages—transport, introduction, establishment, and spread—few studies have explo...

According to the most recent (2005) compendium on the history of the European hedgehog (Erinaceus europaeus) in New Zealand, this small insectivorous mammal was first brought from Europe to the South Island in the 19th century. This introduction has been presumed to be the source of hedgehogs that subsequently spread to the North Island. This view...

Song dialects, as a special case of geographic variation in vocalization, are useful tools in the study of a number of topics ranging from cultural evolution to the emergence of reproductive barriers, and thus continue to be the focus of many bird‐song studies. The Yellowhammer Emberiza citrinella is a common Palaearctic bird with a long breeding s...

New Zealand is home to around 40 alien bird species, but about 80 more were introduced in the 19th century and failed to establish. As most of these introductions were deliberate and documented in detail by the acclimatisation societies responsible for them, New Zealand bird invasions are often used as a model system to unravel what determines the...

Citizen science (CS) has evolved over the past decades as a working method involving interested citizens in scientific research, for example by reporting observations, taking measurements or analysing data. In the past, research on animal behaviour has been benefitting from contributions of citizen scientists mainly in the field of ornithology but...

Biological invasions are not only events with substantial environmental and socioeconomic impacts but are also interesting natural experiments, allowing the study of phenomena such as the cultural evolution of bird song following introduction. We took an excellent opportunity to compare the distribution of dialects of the yellowhammer (Emberiza cit...

The Yellowhammer Emberiza citrinella has several song types that differ in their ending. A research project from the Czech Republic has been analyzing this song variability on a large scale across Europe and New Zealand. The aim of the present work is to examine the situation in Switzerland, for which the first author has recorded the songs of 42 i...

New Zealand harbours a considerable number of alien plants and animals, and is often used as a model region for studies on factors determining the outcome of introductions. Alien birds have been a particular focus of research attention, especially to understand the effect of propagule pressure, as records exist for the numbers of birds introduced t...

The Yellowhammer (Emberiza citrinella) is a bird with a very long history of research in geographic song variation, dating back to the 1920s. Numerous features make the Yellowhammer a suitable model for studying songbird dialects: it is a common and easily recognizable species, has a simple song, keeps singing long into the season, and has dialects...
