New Caledonia: a very old Darwinian island?

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.
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.
Snags and large trees drive higher tree microhabitat densities in strict forest reserves
Patterns of fish species richness in the Seine River basin, France
Variation in fish assemblage structure was examined in different rivers of the Seine Basin. Factor analysis was used to identify similarities among samples and species, and to show ichtyological…
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.
Multiple prismatic calcium phosphate layers in the jaws of present-day sharks (Chondrichthyes; Selachii)
Jaws of large individuals, over 2 m in total length, of the shark speciesCarcharodon carcharias andIsurus oxyrinchus (mako shark), andGaleocerdo cuvieri (tiger shark) and Carcharhinus leucas (bull shark) of the family C Archarhinidae were found to have multiple, up to five, layers of prismatic calcium phosphate surrounding the cartilages.
Phylogeny and evolution of exaggerated traits among the Tingidae (Heteroptera, Cimicomorpha)
- É. Guilbert
- 1 October 2001
The relationships between the studied taxa show that there is a global tendency for pronotal and hemelytral traits to evolve from simple to exaggerated, and such evolution occurs in three clades independently.
Isobathymetric Line Simplification with Conflict Removal Based on a B-spline Snake Model
A new method for the smoothing of isobathymetric lines for marine chart construction, based on a snake model, respects constraints of legibility and safety which impose a direction for curve deformation.
Traits and evolution of wing venation pattern in paraneopteran insects
Several Palaeozoic and early Mesozoic fossils that were ascribed to Paraneoptera are reinterpreted, and the attribution of several to this superorder is confirmed as well as possible attribution of Zygopsocidae (Zygopsocus permianus Tillyard, 1935) as oldest Psocodea.
The indicator side of tree microhabitats: A multi-taxon approach based on bats, birds and saproxylic beetles
National and international forest biodiversity assessments largely rely on indirect indicators, based on elements of forest structure that are used as surrogates for species diversity. These proxies…
