  • Monitoring amphibian species with complex chromatophore patterns: a non-invasive approach with an evaluation of software effectiveness and reliability
    de Julien Renet, Lisa Leprêtre, Jocelyn Champagnon, Philippe Lambret In The Herpetological Journal, 29:1 (January, 2019), 13-22 En ligne : www.thebhs.org[...] The estimation of demographic parameters in wild populations is strengthened by individual identification. For amphibians, various techniques are used to either temporarily or permanently mark individuals for identification. Photo-identification of body patterns offers a non-invasive technique. However, the reliability of photo-recognition software is key to the reliable ...

    de Manon C.M. Hess, François Mesléard, Elise Buisson In Ecological Engineering, 127 (2019), 48-57 En ligne : linkinghub.elsevier.com[...] Many anthropic activities generate soil disturbances, favoring competitive, fast growing invasive plant species at the expense of natives. Active restoration of invasion-resistant plant communities is increasingly recognized as a relevant strategy to combat invasive plant colonization in disturbed areas, but results are often unsatisfying. Historical effects, referred as “priority effects” ...
