New Caledonia: a very old Darwinian island?

- 27 October 2008
New Caledonia must be considered as a very old Darwinian island, a concept that offers many more fascinating opportunities of study, as it is contradicted by geological evidence indicating long Palaeocene and Eocene submersions and by recent biogeographic and phylogenetic studies. Expand
Phylogeny of Dictyoptera: Dating the Origin of Cockroaches, Praying Mantises and Termites with Molecular Data and Controlled Fossil Evidence

The authors' datings suggest that crown-Dictyoptera—and stem-mantises—would date back to the Late Carboniferous, a result compatible with the oldest putative fossil of stem-dictyopteran suborders, and suggests a scenario of replacement in carnivory among polyneopterous insects. Expand
The phylogeny of cockroach families: a cladistic appraisal of morpho-anatomical data
- P. Grandcolas
- 1 March 1996
Seventy-two morpho-anatomical characters were examined in 221 genera belonging to the families Blattidae, Polyphagidae, Blattellidae, and Blaberidae and it was necessary to elevate the Anaplectinae and Pseudophyll... Expand
The phylogeny of termites (Dictyoptera: Isoptera) based on mitochondrial and nuclear markers: Implications for the evolution of the worker and pseudergate castes, and foraging behaviors.

- 1 August 2008
The data support a traditional hypothesis of foraging behavior, in which the evolutionary transition from a one-piece type to a separate life type occurred through an intermediate behavioral form. Expand
Evolution on a shaky piece of Gondwana: is local endemism recent in New Caledonia?
A molecular phylogenetic approach is used to answer the question of whether the diversification of the Neocaledonian cockroach genus Angustonicus belonging to the subfamily Tryonicinae from Australia and New Caledonia is less than two million years old or recent diversifications after Tertiary geological catastrophic events.

Assessing biodiversity with sound: Do acoustic diversity indices reflect phylogenetic and functional diversities of bird communities?
Test theoretically whether functional and phylogenetic diversities could be reflected by acoustic diversity indices in bird communities and showed that acoustic diversity was correlated with phylogenetic diversity, when the branch lengths of the tree were considered, and to functional diversity, especially body mass and reproduction.

Taxonomic bias in biodiversity data and societal preferences

- 22 August 2017
Results show that societal preferences, rather than research activity, strongly correlate with taxonomic bias, which lead to assert that scientists should advertise less charismatic species and develop societal initiatives (e.g. citizen science) that specifically target neglected organisms. Expand
Biodiversity Sampling Using a Global Acoustic Approach: Contrasting Sites with Microendemics in New Caledonia
The hypothesis that global acoustic analyses can detect acoustic differences between sites with similar species richness and similar ecological context, but with different species assemblages is supported. Expand
Acoustic indices for biodiversity assessments: Analyses of bias based on simulated bird assemblages and recommendations for field surveys
To evaluate how measures of acoustic diversity may depart from actual species richness, seven acoustic indices were selected and applied to simulated recordings of bird assemblages under different field conditions and none of the indices fulfilled the three criteria necessary for a perfect proxy of species richness. Expand
Species' diversity in the New Caledonian endemic genera Cephalidiosus and Nobarnus (Insecta: Heteroptera: Tingidae), an approach using phylogeny and species' distribution modelling
The results show that environmental conditions are probably important for the distribution of the genus Cephalidiosus, in conjunction with other factors such as resource (host plant) distribution, but suggest that the same environmental conditions have not influenced the speciation processes and diversification in the genus.
