The ecological connectivity of whale shark aggregations in the Indian Ocean: a photo-identification approach [PDF]

Royal Society Open Science, 2016
Genetic and modelling studies suggest that seasonal aggregations of whale sharks (Rhincodon typus) at coastal sites in the tropics may be linked by migration.

Redesigning photo-ID to improve unfamiliar face matching performance. [PDF]

Journal of Experimental Psychology: Applied, 2014
Viewers find it difficult to match photos of unfamiliar faces for identity. Despite this, the use of photographic ID is widespread. In this study we ask whether it is possible to improve face matching performance by replacing single photographs on ID documents with multiple photos or an average image of the bearer.

Residency, movement patterns, behavior and demographics of reef manta rays in Komodo National Park [PDF]

PeerJ, 2022
Background The reef manta ray (Mobula alfredi) is a globally threatened species and an iconic tourist attraction for visitors to Indonesia’s Komodo National Park (NP). In 2013, manta ray fishing was banned in Komodo NP and its surroundings, preceding the

Photo identification laws and perceptions of electoral fraud

Research & Politics, 2021
Photo identification (ID) laws are often passed on the premise that they will prevent voter fraud and/or reduce perceptions of electoral fraud. The impact of ID laws on perceptions of electoral fraud remains unsettled and is complicated by widespread ...

Skin lesions on common bottlenose dolphins (Tursiops truncatus) from three sites in the Northwest Atlantic, USA. [PDF]

PLoS ONE, 2012
Skin disease occurs frequently in many cetacean species across the globe; methods to categorize lesions have relied on photo-identification (photo-id), stranding, and by-catch data.

Rapid physiological colouration change is a challenge - but not a hindrance - to successful photo identification of giant sunfish (Mola alexandrini, Molidae)

Frontiers in Marine Science, 2023
Photo ID is a common tool in ecology, but has not previously been attempted for the ocean sunfishes (Mola spp., Molidae; ‘molids’). The technique, based on body patterns, could potentially be informative for studying the seasonal occurrence of giant ...

Matching Face Images Taken on the Same Day or Months Apart: the Limitations of Photo ID [PDF]

Applied Cognitive Psychology, 2013
SummaryIt is well‐established that matching images of unfamiliar faces is rather error prone. However, there is an important mismatch between face matching in laboratory and realistic settings. All of the currently available face‐matching databases were designed to establish the baseline level of unfamiliar face perception.

PhotoId-Whale: Blue whale dorsal fin classification for mobile devices.

PLoS ONE, 2020
Photo-identification (photo-id) is a method used in field studies by biologists to monitor animals according to their density, movement patterns and behavior, with the aim of predicting and preventing ecological risks.

A dataset of sea turtle occurrences around the Taiwan coast [PDF]

Biodiversity Data Journal, 2022
We describe a dataset of sea turtle sightings around the coast of Taiwan and its islands (Hoh and Fong 2022). This data collection was initiated by TurtleSpot Taiwan, a citizen-science project that collects sea turtle sighting data. This dataset includes

Viewers base estimates of face matching accuracy on their own familiarity: Explaining the photo-ID paradox [PDF]

Cognition, 2015
Matching two different images of a face is a very easy task for familiar viewers, but much harder for unfamiliar viewers. Despite this, use of photo-ID is widespread, and people appear not to know how unreliable it is. We present a series of experiments investigating bias both when performing a matching task and when predicting other people's ...
