Acoustic detection of radiotracked foraging bats in temperate lowland forests
Publication date: Available online 26 June 2018Source: Mammalian BiologyAuthor(s): Laurent Tillon, Michel Barataud, Sylvie Giosa, Stéphane AulagnierAbstractDuring the recent years studies of bat activity are predominantly based on ultrasound detection. However this method suffers from several biases such as different species call ranges, temporal and habitat-related variability. In order to test the bias linked to the detection of whispering gleaning bats in temperate lowland forests, we equipped several individuals of Myotis bechsteinii and Plecotus auritus with transmitters and followed them on their foraging grounds wh...

Who nose the borzoi? Turbinal skeleton in a dolichocephalic dog breed (Canis lupus familiaris)
Publication date: Available online 26 June 2018Source: Mammalian BiologyAuthor(s): Franziska Wagner, Irina RufAbstractThe domestic dog (Canis lupus familiaris) shows a high intraspecific morphological diversity in its facial shape with a less well-known effect of different snout length types on the intranasal structures, i.e. the turbinal skeleton. Sighthounds are supposed to have a less developed sense of smell in favor of their visual abilities. It has been proposed that within the small space of a sighthound’s slender snout the turbinals are less in number and reduced. In a recent ethological study the English greyhou...

Chemical compounds in Neotropical fruit bat-plant interactions
Publication date: Available online 30 June 2018Source: Mammalian BiologyAuthor(s): Lays Cherobim Parolin, Fabricio Augusto Hansel, Gledson Vigiano Bianconi, Sandra Bos MikichAbstractFruit-eating bats are important seed dispersers in tropical forests. Olfaction seems to be the main sense used by these bats to locate and select food. Previous studies have demonstrated that they identify and select volatile organic compounds, being able to track essential oils of their preferred fruits. However, the specific role played by different compounds in this attraction is largely unknown. Here, we used chromatographic analysis and at...

Do wolves hunt freshwater fish in spring as a food source?
Publication date: July 2018Source: Mammalian Biology, Volume 91Author(s): Thomas D. Gable, Steve K. Windels, Austin T. HomkesAbstractIn April–May 2017 we documented GPS-collared wolves (V034 and V046) from the same pack in northern Minnesota responding to a spring fish (northern pike and presumably white suckers) run, which to our knowledge is the first description of wolves outside of a coastal marine enviroment using fish as a seasonal food source. During this period, we opportunistically observed V046 hunting and consuming fish along a single creek, and documented a substantial number of wolf-killed fish in this area....

Landscape-level field data reveal broad-scale effects of a fatal, transmissible cancer on population ecology of the Tasmanian devil
Publication date: July 2018Source: Mammalian Biology, Volume 91Author(s): C.E. Grueber, S. Fox, K. Belov, D. Pemberton, C.J. HoggAbstractIn order to project and plan for the future of threatened species, conservationists require good quality estimates of basic population parameters, such as population sex ratios and breeding rates. These data can be difficult to obtain in many threatened species where pervasive threats perturb population dynamics. For Tasmanian devils, previous studies at several sites across Tasmania revealed demographic consequences of the fatal and transmissible devil facial tumour disease (DFTD). In th...

Light-independent magnetosensitive behaviour in the Djungarian hamster (Phodopus sungorus)
Publication date: July 2018Source: Mammalian Biology, Volume 91Author(s): Sandra Malewski, Sabine Begall, Hynek BurdaAbstractAlthough magnetoreception is known to be widespread in the animal kingdom, the underlying perception mechanism is still poorly understood, thus representing one of the most relevant research gaps. Currently, a light-independent magnetic-particle mediated mechanism and a light-dependent radical pair mechanism are the two mainly discussed hypotheses for terrestrial animals. Hamsters are highly interesting mammalian models for studies on this topic, because, based on their ecology, both mechanisms seem ...

Bats of the Philippine Islands—A review of research directions and relevance to national-level priorities and targets
Publication date: July 2018Source: Mammalian Biology, Volume 91Author(s): Krizler Cejuela Tanalgo, Alice Catherine HughesAbstractEffective science-based conservation priorities and policies are crucially important to effectively maintain biodiversity into the future. For many threatened species and systems, insufficient information exists to generate priorities, or the mechanisms needed to effectively conserve species into the future, and this is especially important in megadiversity countries like the Philippines, threatened by rapid rates of development and with few overarching strategies to maintain their biodiversity. ...

Habitat occupancy by Artibeus planirostris bats in the Pantanal wetland, Brazil
In this study, we ask whether vegetation structure determines the occupancy by and detectability of the fruit-eating bat Artibeus planirostris among habitats in the Pantanal wetland. We mistnetted bats in the wet and dry seasons, and measured vegetation structures in 36 sites systematically established each 1 km. The probability of occupancy was negatively influenced by the mean distance between trees, with a pronounced decrease in sites with less than about 16 trees per hectare, and the detectability was negatively influenced by moonlight. Artibeus planirostris tended to widely occupy the available vegetation gradient, ...

Evaluation of methods to monitor wild mammals on Mediterranean farmland
Publication date: July 2018Source: Mammalian Biology, Volume 91Author(s): Ana M. Valente, Héctor Binantel, Diego Villanua, Pelayo AcevedoAbstractManagers have, over the years, searched methods with which to monitor wildlife populations that will have the best cost-performance balance for each case scenario. Monitoring techniques are of particular importance when attempting to attain either population density estimates or species richness values, since they enable management decisions to be made. It is, therefore, imperative to assess the capability of the methods employed to detect a wide range of species as a means to ev...

Density-related pattern of variation in body growth, body size and annual productivity in the common hamster
Publication date: July 2018Source: Mammalian Biology, Volume 91Author(s): Ivana Petrová, Martina Petriláková, Jan Losík, Ana Gouveia, Ira E.D. Damugi, Emil TkadlecAbstractBody size is one of the most influential life history traits, often covarying with population density. While decreasing in some organisms, such as large herbivores, body size may increase with population density in small ones, such as voles. Unlike small voles, the common hamster (Cricetus cricetus L.), the endangered Eurasian rodent, does not exhibit cyclic population dynamics but it does have large variation in population numbers and high reproducti...

Unveiling the identity of Kerr's Atlantic tree rat, Phyllomys kerri (Rodentia, Echimyidae)
Publication date: July 2018Source: Mammalian Biology, Volume 91Author(s): Edson Fiedler de Abreu-Júnior, Alexandre Reis Percequillo, Lena Geise, Yuri L.R. Leite, Ana Carolina LossAbstractArboreal spiny rats of the genus Phyllomys are the most diverse group of echimyid rodents in the Atlantic Forest. Many species of Phyllomys have small geographic ranges and are rare in scientific collections. One of them is Phyllomys kerri known from only three specimens collected in a single locality almost 80 year s ago. The identity and the taxonomic validity of this enigmatic species has been questioned in recent decades. Field su...

Mapping risk: Quantifying and predicting the risk of deer-vehicle collisions on major roads in England
Publication date: July 2018Source: Mammalian Biology, Volume 91Author(s): Luca Nelli, Jochen Langbein, Peter Watson, Rory PutmanAbstractWildlife-vehicle collisions are increasing across both Europe and North America, with considerable implications for animal populations themselves, for human safety and in terms of economic cost. Deer are generally the primary species involved in large mammals-vehicle collisions. Classical mitigation measures have however proven to have a limited efficacy. The development of tools aimed at predicting the real-time risk of hitting deer on a particular stretch of road can improve both human a...
