Factors affecting the (in)accuracy of mammalian mesocarnivore scat identification in South‐western Europe
Journal of Zoology - Tập 289 Số 4 - Trang 243-250 - 2013
Pedro Monterroso, Diana Castro, Teresa Luísa Silva, Pablo Ferreras, Raquel Godinho, Paulo C. Alves
AbstractResearch on terrestrial carnivore ecology frequently relies on scat identification and analysis. However, species assignment is commonly based on scat morphology. Potential errors in scat identification are rarely accounted for and might contribute to substantial bias of the final results. Using molecular methods, we evaluate the accuracy of species identif...... hiện toàn bộ
Coexistence of the tiger and the common leopard in a prey‐rich area: the role of prey partitioning
Journal of Zoology - Tập 295 Số 2 - Trang 122-131 - 2015
Sandro Lovari, Chiranjibi Prasad Pokheral, Shant Raj Jnawali, Leonida Fusani, Francesco Ferretti
AbstractEcological theory predicts that sympatric species should avoid competition through diet, spatial and/or temporal partitioning. In carnivores, interference is widespread between species with similar diets. Smaller species are expected to differentiate their diet from that of larger, dominant ones, to reduce the risk of potentially lethal encounters. Interfer...... hiện toàn bộ
Unexpected locomotor behaviour: brachiation by an Old World monkey (Pygathrix nemaeus) from Vietnam
Journal of Zoology - Tập 263 Số 1 - Trang 101-106 - 2004
Craig Byron, Herbert H. Covert
AbstractMore than 70 h of positional behaviour data were collected on the red‐shanked douc langur Pygathrix nemaeus, Delacour's langur Trachypithecus delacouri, Hatinh langur Trachypithecus laotum, and the white‐cheeked crested gibbon Hylobates leucogenys in ...... hiện toàn bộ
Genetic similarity between Akodon olivaceus and Akodon xanthorhinus (Rodentia: Muridae) in Argentina
Journal of Zoology - Tập 247 Số 1 - Trang 43-52 - 1999
Oliver P. Pearson, Margaret F. Smith
AbstractOn an East–West transect in northern Patagonia, the steppe‐inhabiting mouse Akodon (or Abrothrix) xanthorhinus meets the forest‐inhabiting Akodon (Abrothrix) olivaceus on the eastern side of the An...... hiện toàn bộ
Activity patterns of pipistrelle bats (Pipistrellus pipistrellus) in Oxfordshire
Journal of Zoology - Tập 228 Số 1 - Trang 69-80 - 1992
Celia Maier
A maternity colony of pipistrelle bats (Pipisfrellus pipistrellus), in Oxfordshire, was monitored between 1 March 1989 and 6 October 1989. An infra‐red ‘automatic bat counter’ was installed at the roost, to record the number of bats entering and leaving each minute throughout the night. Air temperature, light intensity at sunset, cloud cover, wind speed and rain ...... hiện toàn bộ
Activity patterns of Pipistrelle bats (Pipistrellus pipistrellus) in north‐east Scotland
Journal of Zoology - Tập 190 Số 3 - Trang 285-295 - 1980
Susan M. Swift
Pipistrellus pipistrellus emerge from their nursery roosts in north‐east Scotland about 35 minutes after sunset, at light intensities of between 15 and 35 lux. Cloud cover, windspeed, ambient temperature, rain, light mist and moonlight have no apparent effect on the time or pattern of emergence. Throughout pregnancy and lactation, emergence lasts for about an ho...... hiện toàn bộ
Stable isotope ecology of the common hippopotamus
Journal of Zoology - Tập 276 Số 2 - Trang 204-212 - 2008
Thure E. Cerling, John Harris, John Hart, Prince Kaleme, Hans Klingel, Meave G. Leakey, Naomi E. Levin, RL Lewison, Benjamin H. Passey
AbstractThe diet of African hippopotamids can be documented through stable carbon isotope ratios (13C/12C) analyses of enamel and other tissues. The common hippopotamus Hippopotamus amphibius is widely assumed to be a pure grazer; however, the 13C/12C rati...... hiện toàn bộ
Ecological correlates of hind‐limb length in the Carnivora
Journal of Zoology - Tập 241 Số 2 - Trang 381-408 - 1997
Michelle A. Harris, Karen Steudel
What determines the lengths and proportions of mammalian limbs? While the answer to this question is still largely unknown, a number of workers have recently begun analysing the selection of morphology in a rigorous framework, searching for quantitative links between structure, performance, and their ecological and behavioural context. The present study investigates a variety of ecological...... hiện toàn bộ
Locomotor behaviour in Plio‐Pleistocene sabre‐tooth cats: a biomechanical analysis
Journal of Zoology - Tập 238 Số 3 - Trang 395-413 - 1996
William Anyonge
The locomotor behaviour of some large extinct carnivores, including several species of Plio‐Pleistocene sabre‐tooth cats, is here reconstructed, based on a comparison of the cross‐sectional geometric properties and linear dimensions of their femora and humeri with those of large modern carnivores. The long bones are modelled as simple beams, thereby allowing the use of basic beam theory in...... hiện toàn bộ
Ontogenic dietary changes in South American sea lions
Journal of Zoology - Tập 279 Số 3 - Trang 251-261 - 2009
Massimiliano Drago, Luís Cardona, Enrique A. Crespo, Àlex Aguilar
AbstractStable isotopes of carbon and nitrogen in the skull bones of South American sea lions Otaria flavescens from the Chubut province (Argentina) were analysed to determine whether their feeding habits change during ontogeny. The stable isotope analysis showed that δ13C steadily increased...... hiện toàn bộ
