Abstract The history of the Western Transbaikalia terrestrial fauna of small mammals from the Neogene to the Holocene was traced based on fossil-bearing localities. The main factors influencing the development of the Transbaikalia biota and the environment were the gradually increasing climate cooling and aridization for the last four million years in the region.

Logging Disturbance

Comparisons are reported of the small mammal fauna of three distinct rainforests of south-east Queensland, with emphasis on the faunal response to indirect effects of low soil fertility and past logging disturbance. Cooloola rainforest sites (on infertile podzol soils) supported significantly fewer small mammals than did those at Mt Glorious (on fertile krasnozem soils). This was particularly evident where past logging disturbance was high. However, small mammal species differed in their response to site according to their degree of specialization. The relative abundance of species within Mt Glorious rainforest was comparatively even. In contrast, the small mammal fauna of Cooloola rainforest showed a high dominance-diversity relation with more opportunistic species predominant. Rodent movements and possibly diurnal activity also increased within disturbed secondary Cooloola rainforest. It is proposed that soil infertility, a strong plant commitment to chemical defence against herbivory, and a history of early logging, combine to suppress the abundance and diversity of small mammals within Cooloola rainforests.

This study is a corpus-based diachronic analysis of English reporting parentheticals, i.e. clauses introducing direct speech, placed after or in the middle of the reported message. The aim of the investigation is to trace the development of the construction throughout the history of English, establishing the main factors influencing the choice between VS and SV patterns (i.e. with and without quotative inversion respectively), showing how various reporting verbs were increasingly attracted to the construction, and demonstrating the gradual morphological reduction of the main reporting verbs: quoth and say. The study is based on syntactically annotated corpora of Old, Middle, Early Modern and Late Modern English, and uses other corpora to illustrate more recent changes. The study reveals that reporting clauses do not show regular quotative inversion with all subject types until the Early Modern English period and links this development to the emergence of the comment clause with say. It is also claimed that quotative inversion is not directly derived from the V-2 rule and that parenthetical reporting clauses have functioned as a separate construction since the Old English period.

Sierra Leone is situated at the western edge of the Upper Guinean Forests in West Africa, a recognised biodiversity hotspot which is increasingly threatened by habitat degradation and loss through anthropogenic impacts. The small mammal fauna of Sierra Leone is poorly documented, although bats and rodents account for the majority of mammalian diversity. Based on morphological, genetic and echolocation data, we recorded 30 bat (Chiroptera), three shrew (Soricomorpha) and eleven rodent (Rodentia) species at the Seli River in the north of the country in 2014 and 2016, during a baseline study for the Bumbuna Phase II hydroelectric project. In 2016, 15 bat species were additionally documented at the western fringe of the Loma Mountains, a recently established national park and biodiversity offset for the Bumbuna Phase I dam. Three bat species were recorded for the first time in Sierra Leone, raising the total number for the country to 61. Further, two bat species are threatened and endemic to the Upper Guinean Forest and several taxa of small mammals are poorly known or represent undescribed species. Overall, the habitats of the project area supported a species-rich small mammal fauna including species of global conservation concern. Suitable mitigation measures and/or offsets are necessary to maintain biodiversity and ecosystems in a region that is under high human pressure.

This work is based on a survey of small mammals carried out in the Chapada dos Veadeiros National Park, a natural reserve located in the mountains of the Planalto Central Goiano in the Cerrado of Central Brazil. The 227 specimens collected represented six marsupial and 13 rodent species. Taxonomic, karyologic, and ecologic considerations are present and discussed in the present work. Our data reflected the faunal heterogeneity with respect to both elevation and vegetation because only eight of the 19 species were collected at both high and low elevations. The composition of the small mammal fauna of the park is influenced by predominance of forest formations at low elevations and cerrado with rupestrian areas at high elevations. Presence of endemic species and one undescribed demonstrated that the cerrado has an endemic fauna and a little known diversity of small mammals.

Reconstructions of landscape features at the end of the Middle and Late Neopleistocene were carried out based on the study of the small mammal’s fauna. Faunal data indicate a wide development of steppetype landscapes on the Pre-Altai Plain in the interval from MIS 6 to the beginning of MIS 2. Both in warm and cold seasons, gophers predominated among small mammals in the region; striped hamsters, jerboas, zokors, southern birch mouses, narrow-headed voles and lemmings were less common. All these species are typical inhabitants of open biocenoses of the steppe or tundra-steppe type. Reconstructions based on microteriofauna materials are in good agreement with the study of fossil soils of the Pre-Altai Plain. Fossil soils show the development of steppe and forest-steppe landscapes during periods of warming. During the cold stages, loess deposits accumulated in the region, which can be considered as indicators of cryoarid steppes.

AbstractWe investigated fossil small mammals from a borehole near Moriaanshoofd (Zeeland, southwest Netherlands) in order to get better insights in the fossil mammal faunas that are found in the subsurface in the southwestern Netherlands, and to investigate the age and provenance of the mammal fauna that is being dredged from the deep tidal gullies in the nearby Oosterschelde estuary. The record in the borehole covers Gelasian (Early Pleistocene) to Holocene deposits, represented by six formations. Thirty-nine specimens of small mammals were obtained from the borehole. These fossils derived from the Early Pleistocene marine Maassluis Formation and from directly overlying deposits of a Late Pleistocene age. During Weichselian times (33–24 ka), a proto-Schelde River shaped the northern Oosterschelde area. The river reworked substantial amounts of Early and Middle Pleistocene deposits. At the base of the Schelde-derived fluvial sequence (regionally described as the Koewacht Formation), Gelasian vertebrate faunas were concentrated in the channel lag. The Late Pleistocene channel lag is almost certainly the main source for the rich Early Pleistocene vertebrate faunas with larger mammals dredged from the Oosterschelde.

Significant gaps in knowledge currently exist regarding the small mammal fauna of the Northern Kimberley (NOK) bioregion. Theda Station is a previously unsurveyed pastoral lease in the NOK. The aim of the current study was to determine the presence of small mammals (non-volant, <2 kg) on Theda Station and to compare these findings with those recently obtained on the adjacent Doongan Station. Between 2006 and 2014, 226 site surveys were conducted across 69 sites, with over 26 000 trap-nights encompassing a range of habitats. Thirteen of the 27 small mammal species known to occur in the NOK were detected. Four species (Pseudomys nanus, Rattus tunneyi, Zyzomys argurus and Sminthopsis virginiae) were common, five (Pseudomys delicatulus, Pseudantechinus ningbing, Dasyurus hallucatus, Isoodon macrourus and Petropseudes dahli) were detected less frequently, and four (Leggadina lakedownensis, Hydromys chrysogaster, Planigale maculata and Petaurus breviceps) were occasionally recorded. Our study provides important baseline data for small mammals in this region. It highlights the lack of detailed knowledge of both the presence of, and temporal fluctuations in, the region’s small mammal fauna. This study supports a non-uniform distribution of the small mammal fauna across the NOK, with Theda Station lying within a transition zone between the high rainfall rugged coastal and near-coastal areas and the lower rainfall areas of the east.
