Using GPS-enabled decoy turtle eggs to track illegal trade.

Helen Pheasey, David L Roberts, Daniela Rojas-Cañizales, Carmen Mejías-Balsalobre, Richard A Griffiths, Kim Williams-Guillen,

The insatiable human appetite for wildlife products drives species to extinction, spreads disease and has negative consequences for the economies of source countries [1,2]. As a major transnational enterprise, illegal wildlife trade is valued between eight and 26.5 billion US dollars annually [3,4]. Because law enforcement is often only reactive, ... Read more >>

Accuracy in the identification of orchids of the genus Angraecum by taxonomists and non-taxonomists

Thomas H Mackay-Smith, David L Roberts,

Misidentification of taxa is understudied but has the potential to be a highly problematic issue. If misidentification is prevalent, there could be significant ramifications for work which relies upon a reliable taxonomic base, such as the description of new species, estimating the size of populations and species prioritisation. Here we ... Read more >>

Integrative cognitive remediation for early psychosis: Results from a randomized controlled trial.

Olina G Vidarsdottir, David L Roberts, Elizabeth W Twamley, Berglind Gudmundsdottir, Engilbert Sigurdsson, Brynja B Magnusdottir,

Early application of cognitive remediation may help prevent the development of long-term functional impairments that characterize psychotic disorders. Interventions that encompass both neurocognitive and social-cognitive training may work synergistically to bridge the gap between cognitive gains and functional outcomes in early psychosis. We integrated three cognitive remediation approaches: Neuropsychological Educational ... Read more >>

Wildlife supply chains in Madagascar from local collection to global export

Janine E Robinson, Iain M Fraser, Freya A V St. John, J Christian Randrianantoandro, Raphali R Andriantsimanarilafy, Julie H Razafimanahaka, Richard A Griffiths, David L Roberts,

International trade in wildlife is a complex multi-billion dollar industry. To supply it, many animals are extracted from the wild, sourced from biodiversity-rich, developing countries. Whilst the trade has far-reaching implications for wildlife protection, there is limited information regarding the socio-economic implications in supply countries. Consequently, a better understanding of ... Read more >>
