Book Reference The Diversity of Fish Otoliths, Past and Present by Dirk NOLF.
"The Diversity of Fish Otoliths Past and Present" (222 p. and 359 pl.) by Dirk NOLF is a monograph in natural sciences from the Operational Directorate “Earth and History of Life” of the Royal Belgian Institute of Natural Sciences (www.naturalsciences.be/institute/structure/index_ html#earth). It contains a historical and nomenclatural overview of otolith research in paleontology, with special emphasis on their great impact on the evaluation of the fossil record of teleostean fishes, and a systematic overview (with iconography) of the 1391 fossil species considered to be valid and of all Recent species for which otoliths have been found as fossil. For every species, the stratigraphic and geographic origin of the type material is given, and where available, also the collection numbers and depository of the holotype. Fossil species based on skeletons with otoliths in situ, but which do not have exclusively otolith-based primary types, are also included. An alphabetic list of all the 1797 nominal otolith-based fossil fish species, with an evaluation of their validity and their updated nomenclature is provided.

Book Reference The Diversity of Fish Otoliths, Past and Present
The Diversity of Fish Otoliths, Past and Present (Dirk NOLF)is a publication from the Operational Directorate “Earth and History of Life” of the Royal Belgian Institute of Natural Sciences (www.naturalsciences.be). This new book (222 p. & 359 pl.) contains a historical and nomenclatural overview of otolith research in paleontology, with special emphasis on their great impact on the evaluation of the fossil record of teleostean fishes, and a systematic overview (with iconography) of the 1391 fossil species considered to be valid and of all Recent species for which otoliths have been found as fossil. Otoliths of nearly all recent families and subfamilies are illustrated by at least one example, covering about 95% of all known extant taxa. For every fossil species, the stratigraphic and geographic origin of the type material is given, and where available, also the collection numbers and depository of the holotype. Fossil species based on skeletons with otoliths in situ, but which do not have exclusively otolith-based primary types, are also included. An alphabetic list of all the 1797 nominal otolith-based fossil fish species, with an evaluation of their validity and their actualized nomenclature is provided.

Article Reference The dynamics of ant mosaics in tropical rainforests characterized using the Self-Organizing Map algorithm
Ants, the most abundant taxa among canopy-dwelling animals in tropical rainforests, are mostly represented by territorially-dominant arboreal ants (TDAs) whose territories are distributed in a mosaic pattern (arboreal ant mosaics). Large TDA colonies regulate insect herbivores, with implications for forestry and agronomy. What generates these mosaics in vegetal formations, which are dynamic, still needs to be better understood. So, from empirical research based on three Cameroonian tree species (Lophira alata, Ochnaceae; Anthocleista vogelii, Gentianaceae; and Barteria fistulosa, Passifloraceae), we used the Self-Organizing Map (SOM, neural network) to illustrate the succession of TDAs as their host trees grow and age. The SOM separated the trees by species and by size for L. alata, which can reach 60 m in height and live several centuries. An ontogenic succession of TDAs from sapling to mature trees is shown, and some ecological traits are highlighted for certain TDAs. Also, because the SOM permits the analysis of data with many zeroes with no effect of outliers on the overall scatterplot distributions, we obtained ecological information on rare species. Finally, the SOM permitted us to show that functional groups cannot be selected at the genus level as congeneric species can have very different ecological niches, something particularly true for Crematogaster spp. which include a species specifically associated with B. fistulosa, non-dominant species and TDAs. Therefore, the SOM permitted the complex relationships between TDAs and their growing host trees to be analyzed, while also providing new information on the ecological traits of the ant species involved.

Article Reference The earliest Eocene mammal fauna of the Erquelinnes Sand Member near the French-Belgian border
The earliest Eocene Erquelinnes site was discovered in 1880, but its mammal fauna has been frequently ignored. This paper provides the first detailed overview of the Erquelinnes mammals since 1929. The new faunal list doubles the known diversity at Erquelinnes to a total of 16 species, now also including amphilemurids, hyaenodontids, mesonychids, louisinids, equids and diacodexeids. The majority of the Erquelinnes species is also present in the earliest Eocene Dormaal MP7 reference fauna, with as most notable exceptions the presence of a potentially dwarfed specimen of Dissacus, and of two perissodactyl taxa at Erquelinnes. The ceratomorph perissodactyl Cymbalophus cuniculus is also known from the earliest Eocene of England, but a specimen identified as cf. Sifrhippus sandrae is closely similar to contemporaneous primitive North American equids. This specimen represents the oldest unambiguous European equid and highlights faunal similarities between Europe and North America during this time interval. Faunal differences between Erquelinnes and Dormaal seem mostly due to depositional differences, and the Erquelinnes fauna represents a typical earliest Eocene fauna, closely similar to other MP7 and PEI faunas in Europe.
