Determining the habitat use of Varecia variegata in Maromizaha Protected Area, Madagascar [PDF]

open access: yes, 2017
Understanding the interaction between frugivores and their habitat is necessary for both primate and forest preservation. In Madagascar, Varecia variegata, are the most highly frugivorous lemur in the Lemuridae family This project examined the habitat

Rate variation during molecular evolution: creationism and the cytochrome c molecular clock [PDF]

open access: yes, 2017
Molecular clocks based upon amino acid sequences in proteins have played a major role in the clarification of evolutionary phylogenies. Creationist criticisms of these methods sometimes rely upon data that might initially seem to be paradoxical.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Gestion en métapopulation de Propithecus coronatus: une approche originale et multidisciplinaire pour la conservation d’une espèce en danger à Madagascar

open access: yesRevue de Primatologie, 2011
The crowned sifaka, Propithecus coronatus, is one of the most endangered lemur species in Madagascar. A conservation project has been established in partnership between GERP (Groupe d’Etude et de Recherche sur les Primates de Madagascar), The Aspinall ...

Investigation of marmoset hybrids (Cebuella pygmaea x Callithrix jacchus) and related Callitrichinae (Platyrrhini) by cross-species chromosome painting and comparative genomic hybridization [PDF]

open access: yes, 2005
We report on the cytogenetics of twin offspring from an interspecies cross in marmosets (Callitrichinae, Platyrrhini), resulting from a pairing between a female Common marmoset (Callithrix jacchus, 2n = 46) and a male Pygmy marmoset (Cebuella pygmaea, 2n

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

open access: yesBiological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Fragmentation des habitats et le devenir des lémuriens du Sud et du Sud-ouest de Madagascar

open access: yesRevue de Primatologie, 2011
Once called "green island", Madagascar is now one of the most degraded part of the world due to all kinds of human activities. Since men arrived on the island, progressive degradation of forests became more and more alarming for the survival of lemur ...

Depth of Edge Influence in a Madagascar Lowland Rainforest and Its Effects on Lemurs’ Abundance

open access: yesLand, 2022
Edge effects result from interactions between adjacent habitats, which can modify abiotic and biotic conditions and produce various negative effects on biodiversity.

Familiars: representing Facebook users’ social behaviour through a reflective playful experience [PDF]

open access: yes, 2009
In this paper, we describe the design and development of a social game called Familiars. Inspired by the daemons in Pullman’s “Dark Material” trilogy, Familiars are animal companions that sit on your Facebook profile and change into different animal ...

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

open access: yesOikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.
