How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Article

Previous studies have demonstrated a correlation between longevity and brain size in a variety of taxa. Little research has been devoted to understanding this link in parrots; yet parrots are well-known for both their exceptionally long lives and cognitive complexity. We employed a large-scale comparative analysis that investigated the influence of...

Is it possible to slow the rate of ageing, or do biological constraints limit its plasticity? We test the ‘invariant rate of ageing’ hypothesis, which posits that the rate of ageing is relatively fixed within species, with a collection of 39 human and nonhuman primate datasets across seven genera. We first recapitulate, in nonhuman primates, the hi...

In this article we present a standardized dataset on 6659 songbirds (Passeriformes) highlighting information relevant to species conservation prioritization with a main focus to support the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Data were collected from both scientific and grey literature as well as...
Article
Full-text available
We collated and synthesized information on 1,226 Elasmobranch species (i.e., sharks, rays, and skates) globally from a wide range of sources. We obtained curated and standardized data from online databases, legal documents, press releases, and websites. All data were standardized according to the taxonomic nomenclature described in the Catalogue of...

We collected data on the trade of seven turtle and tortoise species endemic to Indonesia and Malaysia (Amyda cartilaginea, Batagur borneoensis, Cuora amboinensis, Carettochelys insculpta, Heosemys annandalii, Heosemys grandis, and Heosemys spinosa). We collated data for: the operations and economics of three breeding farms and one ranching facility...

Is it possible to slow the rate of aging, or do biological constraints limit its plasticity? We test this ‘invariant rate of aging’ hypothesis with an unprecedented collection of 39 human and nonhuman primate datasets across seven genera. We first recapitulate, in nonhuman primates, the highly regular relationship between life expectancy and lifesp...
Article
Full-text available
Biodiversity loss is a major challenge. Over the past century, the average rate of vertebrate extinction has been about 100-fold higher than the estimated background rate and population declines continue to increase globally. Birth and death rates determine the pace of population increase or decline, thus driving the expansion or extinction of a sp...
Technical Report
Short reviews of known information relating to breeding biology and captive husbandry and any impacts, if relevant, of removal of founder stock from the wild for species selected by AC29
Article
Generation time is a fundamental component of extinction risk assessments for the International Union for Conservation of Nature’s Red List of Threatened Species. The calculation of generation time requires age‐specific data on survival and fecundity rates and knowledge of population growth rates. These data are generally lacking for threatened spe...
Technical Report
According to the CITES Decision 17.229 (a), the objective of this report is to provide a review of the number of facilities keeping Asian big cats (Felidae spp.) in captivity in the territories of Parties and the number of Asian big cats kept in these facilities. We compiled information from existing databases, published literature, grey literature...

Project
Given the current ocean crises, we believe that populations held in the world's aquariums can play an important role in the conservation of wild populations. Here we explore this issue from different perspectives.
Project
My team and I, we are working on different projects to use data from captive and wild populations to assess the laundering of species as a captive breed in the International Markets. We have worked with the CITES Secretariat on reports and are collaborating with MONITOR, TRAFFIC South East Asia and the IUCN ASAP. Our first projects are mostly devoted to turtles and sharks and rays.
Project
Determine limits of captive breeding by analysing zoo data from the ZIMS Species360 database
