Cross-Modal Recognition Of Familiar Conspecifics In Goats, Benjamin J. Pitcher, Elodie F. Briefer, Luigi Baciadonna, Alan G. Mcelligott

Recognition Collection

When identifying other individuals, animals may match current cues with stored information about that individual from the same sensory modality. Animals may also be able to combine current information with previously acquired information from other sensory modalities, indicating that they possess complex cognitive templates of individuals that are independent of modality. We investigated whether goats (Capra hircus) possess cross-modal representations (auditory–visual) of conspecifics. We presented subjects with recorded conspecific calls broadcast equidistant between two individuals, one of which was the caller. We found that, when presented with a stablemate and another herd member, goats looked towards the caller sooner and …

New Data On Small Mammals Of Neolithic Sites And Burial Grounds In Mongolia, Fedora Khenzykhenova, Nataly Schepina, Dashzeveg Tumen, Myagmar Erdene, Nataly Tsydenova, D. Khatanbaatar

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

New data about animals obtained by Mongolian paleoanthropologists, National University of Mongolia and Russian archaeologist, Institute of Mongolian, Buddist and Tibetan studies, Siberian Branch, Russian Academy of Sciences were obtained under the direction of Professors Dashzeveg Tumen and Myagmar Erdene. The faunistic materials were excavated from localities of different origins including burial grounds, old cities, and Neolithic sites in different areas of Mongolia. Species composition of the large mammal fauna included two species and, the small mammal fauna was represented by two species of lagomorphs, and six species of rodents which are also components of the recent fauna of Mongolia.

A Revised Checklist Of Mongolian Mammal Species, V. S. Lebedev, A. A. Bannikova, Ya. Adiya, S. Shar, A. V. Surov

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

A revised annotated checklist of Mongolian mammals is presented, supplemented with comments on modifications in species- and genus-level taxonomy introduced over the last 30 years. The checklist includes 140 species compared to 124 species recognized three decades ago by SOKOLOV & ORLOV (1980). Since then, four species were newly described; seven species were registered for the first time on Mongolian territory. Names for more than 20 taxa have changed, on most occasions this change occurred not for purely nomenclatural reasons but rather as a result of taxonomic revisions at the species level which have elevated the rank of many nominal …

Seasonal Change In The Avian Hippocampus., David F Sherry, Scott A Macdougall-Shackleton

Brain and Mind Institute Researchers' Publications

The hippocampus plays an important role in cognitive processes, including memory and spatial orientation, in birds. The hippocampus undergoes seasonal change in food-storing birds and brood parasites, there are changes in the hippocampus during breeding, and further changes occur in some species in association with migration. In food-storing birds, seasonal change in the hippocampus occurs in fall and winter when the cognitively demanding behaviour of caching and retrieving food occurs. The timing of annual change in the hippocampus of food-storing birds is quite variable, however, and appears not to be under photoperiod control. A variety of factors, including cognitive performance, …

Collapse Of An Ecological Network In Ancient Egypt, Justin Yeakel, Mathias Pires, Lars Rudolf, Nathaniel Dominy

Dartmouth Scholarship

The dynamics of ecosystem collapse are fundamental to determining how and why biological communities change through time, as well as the potential effects of extinctions on ecosystems. Here, we integrate depictions of mammals from Egyptian antiquity with direct lines of paleontological and archeological evidence to infer local extinctions and community dynamics over a 6,000-y span. The unprecedented temporal resolution of this dataset enables examination of how the tandem effects of human population growth and climate change can disrupt mammalian communities. We show that the extinctions of mammals in Egypt were nonrandom and that destabilizing changes in community composition coincided with …

High Muscle Mitochondrial Volume And Aerobic Capacity In A Small Marsupial (Sminthopsis Crassicaudata) Reveals Flexible Links Between Energy-Use Levels In Mammals, Terence Dawson, Koa Webster, Enhua Lee, William A. Buttemer

Faculty of Science, Medicine and Health - Papers: part A

We investigated the muscle structure–function relationships that underlie the aerobic capacity of an insectivorous, small (~15 g) marsupial, Sminthopsis crassicaudata (Family: Dasyuridae), to obtain further insight into energy use patterns in marsupials relative to those in placentals, their sister clade within the Theria (advanced mammals). Disparate hopping marsupials (Suborder Macropodiformes), a kangaroo (Macropus rufus) and a rat-kangaroo (Bettongia penicillata), show aerobic capabilities as high as those of ‘athletic’ placentals. Equivalent muscle mitochondrial volumes and cardiovascular features support these capabilities. We examined S. crassicaudata to determine whether highly developed aerobic capabilities occur elsewhere in marsupials, rather than being restricted to the …

Pleistocene Faunal Fossils From Bayangol I Site, Bulgan Aimag, Mongolia, Takao Sato, Fedora Khenzykhenova, Toshiaki Tsurumaru, Masao Ambiru, Jun Takakura, Yoshiaki Otsuka, Shigeo Iida, Natalya Schepina, Batmunkh Tsogtbaatar

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

During excavation of the Bayan-gol I Palaeolithic site in the Bulgan Aimak, Mongolia, some faunistic remains were recovered attributable to Aves (two species), Anura (two species), and mammals (three species). The fossil remains bear a considerable similarity to the corresponding species of today in Mongolia.

Beitrag Zur Säugetierfauna Des Staatlichen Naturschutzgebietes Azas In Tyva/Südsibirien = Contributions To Fauna And Ecology Of Small Mammals Of State Nature Reserve “Azas” In The Republic Of Tyva /South Siberia, Annegret Stubbe, Michael Stubbe, V. V. Unžakov, A. P. Saveljev, N. I. Putincev, W. Stubbe

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

During 1988-2004 Russian and German biologists carried out a research of biodiversity of the mountain taiga within the territory of State Nature Reserve “Azas” (Republic of Tyva/Russia). Along with executing the main task – studying and development of an aboriginal population of Tuvinian beavers Castor fiber tuvinicus – materials on the fauna of small mammals of the Todzha kettle were collected. On the basis of samples (about 550 collected micromammals) information on the occurrence, reproduction and morphometric characteristics of four species of Insectivora, six species of Chiroptera and eleven species of small Rodentia inhabiting the territory of the reserve “Azas” …

Facts From Faeces: Prey Remains In Wolf, Canis Lupus, Faeces Revise Occurrence Records For Mammals Of British Columbia’S Coastal Archipelago, Michael H. H. Price, Chris T. Darimont, Neville N. Winchester, Paul C. Paquet

Biogeography and Ecological Opportunity Collection

Archipelagos often harbour taxa that are endemic and vulnerable to disturbance. Conservation planning and research for these areas depend fundamentally on accurate and current taxonomic inventories. Although basic ecological information is in its infancy, the temperate rainforest islands of coastal British Columbia are undergoing rapid human-caused modification, particularly logging. We report herein new mammal records for these islands as determined by prey remains in the faeces of Wolves (Canis lupus), the area’s apex mammalian terrestrial predator. Of particular interest is our detection of Marten (Martes americana) on islands previously inventoried and island occupancy by Moose (Alces alces), which have apparently …

An Allometric Comparison Of Microsomal Membrane Lipid Composition And Sodium Pump Molecular Activity In The Brain Of Mammals And Birds, Anthony J. Hulbert, Paul Else, Nigel Turner

Faculty of Health and Behavioural Sciences - Papers (Archive)

Previous research has shown that the lipid milieu surrounding membrane proteins may be an important factor in determining their activity. To investigate this we have examined sodium pump molecular activity and microsomal membrane lipid composition in the brain of five mammalian and eight avian species ranging in size from 30 g mice to 280 kg cattle and 13 g zebra finches to 35 kg emus, respectively. Sodium pump (Na⁺,K⁺-ATPase) activity was higher in the smaller species and showed a significant allometric decline with body mass in both the mammals (μmol P_i h^-1 mg wet …

Mammals, Birds, And Butterflies At Sodium Sources In Northern Ontario Forests, D. Fraser

Feeding Behavior Collection

Wildlife seen at natural sodium-rich springs and at roadside pools contaminated by highway de-icing salt in northern Ontario included two species of wild ungulates, one species of rodent, three species of birds, and two species of butterflies. The three birds were finches of the sub-family Carduelinae, noted for feeding almost exclusively on plant material. The mammalian species were also herbivorous. Apart from Porcupines (Erethizon dorsaturn), small mammals were rarely seen at the saltwater locations, perhaps because of their apparent preference to ingest salt in solid form rather than in water.

Abundance And Distribution Of Large Mammals In The Upper Ogun Game Reserve, Oyo State, Nigeria, T. A. Afolayan, K. R. N. Milligan, S. O. Salami

Nature Collection

In this study, three indirect methods [counts of animal droppings, footprints, and tracks) were used as indices to estimate the abundance and distribution of large mammals in the Upper Ogun Game Reserve, which is located in a typical Southern Guinea savanna zone of Nigeria. Thirteen animal species were recorded; kob, bushbuck, hartebeest, roan antelope and duicker were the most abundant. The distribution of large mammals appears to be controlled by several factors: accessibility to the River Ogun [the main source of water in the reserve), availability of food and cover, and the extent of illegal hunting.
