Article
Full-text available
The unsustainable use of wildlife increases the risk of species extinction. In biodiversity-rich Indonesia, information on the scale of wildlife use is limited and requires further study. To address this, we explored the potential of text messaging (short message service; SMS) surveys to investigate levels and spatial patterns of domestic wildlife...
Article
Full-text available
Changing public behaviour is an essential step for successful conservation, and can be achieved through effective use of message framing. However, its use in the conservation sector is not well-studied. We first performed a content analysis to assess what types of framing styles environmental non-governmental organisations (ENGOs) often employ for...
Article
Full-text available
Flagship species are an important tool for mobilizing support for conservation. Here, we extend this concept to include individual organisms, whose characteristics, fates, and connections to people can garner public attention, attract conservation support, and spur activism. Flagship individuals typically share a similar suite of characteristics, i...
Article
Full-text available
Celebrities can generate substantial attention, and influence public interest in species. Using a large‐scale examination of publicly available data, we assessed whether species across six taxonomic groups receive more attention on Wikipedia jj(according to their page views) when named after celebrities than when not. We conducted our analysis for...
Article
Full-text available
The use of English as the common language of science represents a major impediment to maximising the contribution of non-native English speakers to science. Yet few studies have quantified the consequences of language barriers on the career development of researchers who are non-native English speakers. By surveying 908 researchers in environmental...

Co‐design, an approach that seeks to incorporate the experiences and perspectives of different stakeholders, is increasingly being used to develop audience‐oriented behaviour change interventions. The complexity of wildlife consumption behaviour makes the co‐design approach an important potential tool for the design of conservation interventions th...
Preprint
Sharks, rays and their cartilaginous relatives (Class Chondricthyes, herein ‘sharks’) are amongst the world’s most threatened species groups, primarily due to overfishing, which in turn is driven by complex market forces including demand for fins. Understanding the high-value shark fin market is a global priority for conserving shark and rays, yet...
Article
Societal awareness of, and engagement with, environmental problems is a critical prerequisite for effective conservation programs. Research has revealed a strong general pattern whereby public attention received by cultural products diminishes over time. If transposed to conservation, this transience of societal attention is likely to be of major i...
Chapter
Full-text available
Historically, conservationists have focused on financial and technical solutions to human-wildlife conflicts (Redpath et al., 2013). It has become clear that although these are important to generate a context where change is possible, more attention to human behaviour is needed to achieve longer-term human-wildlife coexistence (Veríssimo & Campb...
Article
Full-text available
The first target of the Convention for Biological Diversity (Aichi target 1) was to increase public awareness towards the values of biodiversity and actions needed to conserve it - a key prerequisite for other conservation targets. Monitoring success in achieving this target at a global scale has been difficult until recently. However, the increase...

Full-text available
As human-wildlife conflicts become more frequent, serious and widespread worldwide, they are notoriously challenging to resolve, and many efforts to address these conflicts struggle to make progress. These Guidelines provide an essential guide to understanding and resolving human-wildlife conflict. The Guidelines aim to provide foundations and prin...
Chapter
Full-text available
Impact evaluations assess the causal link between an action (e.g. erecting a fence) and the outcomes (e.g. a change in the rate of crop raiding by elephants). This goes beyond understanding whether a project has been implemented (e.g. whether activities were completed) to understanding what changes happened due to the actions taken and why they...

Regulation of natural resource use might have unintended spillover impacts beyond the policy targets. Overexploitation is a major cause of species extinction and banning wildlife trade is a common and immediate measure to tackle it. However, few rigorous studies have investigated consequences of wildlife trade bans, and those few studies have focus...
Article
Full-text available
Illegal wildlife trade (IWT) is threatening many species across the world. It is important to better understand the scale and characteristics of IWT to inform conservation priorities and actions. However, IWT usually takes place covertly, meaning that the data on species, trade routes and volumes is limited. This means that conservationists often h...

The archipelago state of Malta is renowned as a “blackspot” for illegal bird hunting. Since joining the European Union (EU), Maltese hunters have experienced restrictions on what and how much they can hunt. This article describes Malta's current enforcement efforts which, assisted by the Army and by volunteers from conservation groups, exceed EU st...
Article
The ongoing global biodiversity crisis not only involves biological extinctions, but also the loss of experience and the gradual fading of cultural knowledge and collective memory of species. We refer to this phenomenon as 'societal extinction of species' and apply it to both extinct and extant taxa. We describe the underlying concepts as well as t...

When striving to motivate support for conservation, there is often a bias in focus and funding for some species over others (such as flagship species, because they are attractive and recognisable to the public). However, species’ names can also influence peoples’ attitudes and feelings towards them, and celebrity endorsement can lead to increased a...
Article
Full-text available
Reducing demand for wildlife products has been recognised as an important global priority. However, consumer demand is a complicated phenomenon involving numerous interacting biological and socio-economic factors, operating at a range of scales and time periods. The demand for elephant ivory is an excellent illustration of the gaps in our current k...
