(Table 1) Date, deployment location, tag longevity, and satellite data of humpback whales (Megaptera novaeangliae) off New Caledonia

Knowledge of the local and migratory movements of humpback whales (Megaptera novaeangliae) from New Caledonia is very limited. To investigate this topic, we attached satellite-monitored tags to 12 whales off southern New Caledonia. Tag longevity ranged from 1 to 52 days (X = 22.5 days). Tagged whales generally moved to the south or southeast, with several spending time in a previously unknown seamount habitat named Antigonia before resuming movement, generally toward Norfolk Island or New Zealand. However, 1 female with a calf traveled the entire length of the western coast of New Caledonia (~450 km) and then west in the direction of the Chesterfield Reefs, a 19th century American (''Yankee'') whaling ground. None of the New Caledonia whales traveled to or toward eastern Australia, which is broadly consistent with the low rate of interchange observed from photo-identification comparisons between these 2 areas. The connections between New Caledonia and New Zealand, together with the relatively low numbers of whales seen in these places generally, support the idea that whales from these 2 areas constitute a single population that remains small and unrecovered.

Brachiopods in Early Carboniferous

Changes in Mississippian global paleogeography derived from the reconfiguration of the continents, a reversal in ocean currents and global cooling. Although the tectonic and climatic changes are well-documented, their effects on the distribution of brachiopod fauna are poorly documented. Here we present systematic quantitative analyses on global paleobiogeography based on a global brachiopod database from the Mississippian (i.e., Tournaisian, Visean, and Serpukhovian). The dataset consists of 2123 species of 344 brachiopod genera from 1156 localities. Our results reveal that global provincialism was not evident during the Tournaisian and Visean Stages. Two realms, i.e., the Gondwanan and Paleoequatorial Realms, are recognized during the Tournaisian. The Paleoequatorial Realm dominates during the Visean Stage, whereas the Gondwanan Realm is not documented due to the absence of data points. In contrast to the early and middle Mississippian stages, faunal provincialism is greatly enhanced in the Serpukhovian Stage with Paleotethyan and North American realms easily distinguished. This indicates that the Rheic Ocean was closed before the Serpukhovian due to the collision between Gondwana and Laurussia, that disrupted faunal interchange between the Paleotethys and North America. In addition, the paleolatitude-related thermal gradient was enhanced and the Boreal Realm was distinguished from the Paleotethyan Realm during the onset of the Late Palaeozoic Ice Age (LPIA) in the Serpukhovian. The paleolatitude diversity gradient pattern further shows a distinct shift of diversity center from the southern tropic zone in the Tournaisian and Visean to the northern tropic zone in the Serpukhovian.

PanPlot - software to visualize profiles and core logs

The program PanPlot was developed as a visualization tool for the information system PANGAEA. It can be used as a stand-alone application to plot data versus depth or time or in a ternary view. Data input format is tab-delimited ASCII (e.g. by export from MS-Excel or from PANGAEA). The default scales and graphic features can individualy be modified. PanPlot graphs can be exported in platform-specific interchange formats (EMF, PICT) which can be imported by graphic software for further processing.
