Towards liveness detection in keystroke dynamics: Revealing synthetic forgeries

Systems and Soft Computing, 2022
While the accuracy of keystroke dynamics verification systems has traditionally been evaluated using a zero-effort attack model, the current trend is to recognize that such an approach is too optimistic.

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

People and Nature, EarlyView.
Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

On the shape of timings distributions in free-text keystroke dynamics profiles

Heliyon, 2021
Keystroke dynamics is a soft biometric trait. Although the shape of the timing distributions in keystroke dynamics profiles is a central element for the accurate modeling of the behavioral patterns of the user, a simplified approach has been to ...

The collective application of shorebird tracking data to conservation

Conservation Biology, EarlyView.
Abstract Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia

Conservation Biology, EarlyView.
Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...
