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 ...

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

A mark-recapture approach for estimating population size of the endangered ringed seal (Phoca hispida saimensis).

PLoS ONE, 2019
Reliable population estimates are fundamental to the conservation of endangered species. We evaluate here the use of photo-identification (photo-ID) and mark-recapture techniques for estimating the population size of the endangered Saimaa ringed seal ...

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.

NOTE: National Benefits of Ethiopia’s Digital ID Project and Its Implementation (Amharic)

Mizan Law Review, 2023
Identification system is divided into Foundation ID and Functional ID. There is the need for foundational ID in Ethiopia that fulfills international standards even though Kebele ID serves as a de-facto foundational ID.

Long-Term Photo-Identification Reveals the Population Dynamics and Strong Site Fidelity of Adult Whale Sharks to the Coastal Waters of Donsol, Philippines

Frontiers in Marine Science, 2018
Donsol in the Philippines is the longest running community-based whale shark (Rhincodon typus) ecotourism site in Southeast Asia, with peak visitation in 2012 of over 27,000 tourists. In order to understand this aggregation and the importance of the area
