| This study compared niche breath, prey size, and diet variability in two pairs of sympatric species of terrestrial insectivorous birds, each pair containing one species that can persist in small forest fragments and one that does not. The pairs were Myrmeciza ferruginea and Sclerurus rufigularis; and Formicarius colma and F. analis, respectively. The prey availability in forest fragments was also sampled and compared to the availability in continuous forests. Niche breath indices did not differ between pair members, but diet variability differed in the opposite direction from that hypothesized. Although the two bird species most vulnerable to fragmentation fed on larger prey than less vulnerable species, prey availability, including that based on prey size... |

| The Czech locality of Merkur-Nord (MN 3) has yielded one species of erinaceid and five species of talpids. The hedgehogs are represented by a few fossils of Galerix only. The talpid assemblage is characterised by a dominance of Mygalea magna. The position of Mygalea within the Desmaninae, which previously had been open to some doubt, could be ascertained. The excellent preservation of the material, including post-cranial remains, allowed the association of humeri to all of the five talpid species. The position of Desmanella, represented by the new species D. gudrunae, as a uropsiline talpid is confirmed, as for the first time a Desmanella dentition could be associated with a uropsiline type of humerus. Overall, the talpid assemblage shows its greatest... |

| The hominid bearing strata from the Liang Bua cave on Flores have yielded a large amount of microvertebrate remains. Among these are three mandibles of shrews, the first record of fossil insectivores from the island. The fossils, representing two different species, are not referable to any of the known Recent shrews from Flores, and are probably part of the extinct insular fauna. Since mandibles alone do not offer sufficient characters to allow even a generic classification, they are published in open nomenclature as Crocidura or Suncus sp. A, and sp. B. Από τα στρώματα με Hominidae από το σπήλαιο Liang Bua της νήσου Φλόρες έχει ανασκαφτεί ένας σημαντικός αριθμός ευρημάτων μικροθηλαστικών.

| The insectivores from the Thrace locality of Karydia (MN 4) are described, as well as an erinaceid molar from thenearby locality of Komotini (MN 5). The Karydia assemblagecontains the same genera of the Greek MN 4 localityAliveri, with the addition of a shrew and of Plesiosorex. An M2 of the latter is the southernmost occurrence of this genus, and the first record from the Mediterranean area. At the species level there are differences between Karydia and Aliveri. As Galerix kostakii n.sp. from Karydia is interpreted as a descendant of G. symeonidisi from Aliveri, a younger age for the Thrace locality, as was already assumed on the basis of the rodents, is confirmed. A model is proposed in which the symeondisi-kostakii lineage gives rise to Parasorex, of... |

| Floating litter banks are an ephemeral habitat consisting of branches, twigs, flowers, seeds, and fruits that are trapped on the stream water surface by a variety of retention mechanisms. These heterogeneous materials form a deep layer of dead plant matter that is colonized by a variety of organisms, including fish that forage on the aquatic macroinvertebrates found in this unique habitat. In this study, we aimed to characterize which fish species occupy the floating litter banks and their trophic characteristics, as well as determine if fish assemblage composition and species richness can be predicted by the size of the floating litter banks. Fish sampling was conducted in five rivers located in the Amazon basin. Of the 31 floating litter banks sampled... |

| Introduction Research of Miocene and Pliocene insectivores has a long history in Germany. Already in the middle of the 19th century Miocene insectivore species have been described from South German localities. Most of these were authored by Herman von Meyer, who deserves to be named a pioneer of German insectivores research. Weisenau, today part of the city of Mainz, is the type locality of Dimylus paradoxus described by von Meyer (1846:473). Haslach near Ulm yielded the type of Cordylodon haslachensis, also described by von Meyer (1859: 174). The widely known Steinheim fauna yielded among others the type of Parasorex socialis, again described by von Meyer (1865:884). Von Meyer often received fossils from private collectors for determination. Usually, he... |

| The micromammal fauna from the Middle Miocene (Middle Aragonian) of La Retama, eastern central Spain, is described. It is a relatively poor rodent fauna composed by ten species only, associated to a highly diverse bat fauna, which includes five genera. The insectivores are represented by two species. This fossil assemblage has been correlated to zone Db (MN 5). The palaeoenvironmental reconstruction based on micromammals indicates open and dry conditions for this locality. Se describen los micromamíferos del Mioceno medio (Aragoniense medio) de La Retama, sector centro-oriental español. La fauna de roedores es relativamente pobre y está compuesta únicamente por diez especies. Sin embargo, cabe destacar la elevada diversidad de los quirópteros,... |
