Evidence from Vibrissal Musculature and Function in the Marsupial Opossum Monodelphis Domestica
3483 The Journal of Experimental Biology 216, 3483-3494 © 2013. Published by The Company of Biologists Ltd doi:10.1242/jeb.087452 RESEARCH ARTICLE The evolution of active vibrissal sensing in mammals: evidence from vibrissal musculature and function in the marsupial opossum Monodelphis domestica Robyn A. Grant1, Sebastian Haidarliu2, Natalie J. Kennerley3 and Tony J. Prescott3,* 1Division of Biology and Conservation Ecology, Manchester Metropolitan University, Manchester M1 5GD, UK, 2Department of Neurobiology, The Weizmann Institute, Rehovot, Israel and 3Department of Psychology, University of Sheffield, Western Bank, Sheffield S10 2TN, UK *Author for correspondence ([email protected]) SUMMARY Facial vibrissae, or whiskers, are found in nearly all extant mammal species and are likely to have been present in early mammalian ancestors. A sub-set of modern mammals, including many rodents, move their long mystacial whiskers back and forth at high speed whilst exploring in a behaviour known as ‘whisking’. It is not known whether the vibrissae of early mammals moved in this way. The grey short-tailed opossum, Monodelphis domestica, is considered a useful species from the perspective of tracing the evolution of modern mammals. Interestingly, these marsupials engage in whisking bouts similar to those seen in rodents. To better assess the likelihood that active vibrissal sensing was present in ancestral mammals, we examined the vibrissal musculature of the opossum using digital miscroscopy to see whether this resembles that of rodents. Although opossums have fewer whiskers than rats, our investigation found that they have a similar vibrissal musculature. In particular, in both rats and opossums, the musculature includes both intrinsic and extrinsic muscles with the intrinsic muscles positioned as slings linking pairs of large vibrissae within rows. -

Rita1,*, M. Drago1,2, F. Galimberti3, L. Cardona1 1Biodiversity Research Institute (IRBio) and Department of Evolutionary Biology, Ecology and Environmental Science, Faculty of Biology, University of Barcelona, Avinguda Diagonal 643, 08028 Barcelona, Spain 2Departamento de Ecología & Evolución, Centro Universitario Regional Este (CURE), Universidad de la República, Tacuarembó s/n, 20000 Maldonado, Uruguay 3Elephant Seal Research Group, Sea Lion Island, Falkland Islands ABSTRACT: Individual specialization can be an advantageous strategy that increases predation success and diminishes intra-population competition. However, trophic specialization can be a handicap in changing environments if the individuals are unable to use different prey or feeding grounds in response to change. Southern elephant seals Mirounga leonina allow us to explore this trade-off as they migrate, returning to haul out on land, for 2 extended periods, to breed and to moult. They fast during both periods, but the energetic cost is higher during the breeding season, leading to a poorer body condition after the breeding fast than after the moulting fast. We ana- lysed the carbon (δ13C) and nitrogen (δ15N) isotopic composition of skin and fur samples from Falk- land Islands elephant seals. The isotopic values provided information about the foraging strategy of the seals during the pre-breeding season and pre-moulting season, respectively. We assessed individual specialization as the variation between periods of an individual with respect to the variability of the whole population. -
Historical Perspectives Nobuyuki Miyazaki (Born 4 August 1946)
Aquatic Mammals 2012, 38(2), 189-203, DOI 10.1578/AM.38.2.2012.189 Historical Perspectives Nobuyuki Miyazaki (born 4 August 1946) Nobuyuki Miyazaki began his career as a research associate at the University of Ryukyus, Japan, obtaining his Ph.D. in 1975 under Professor Nishiwaki. He established a Japanese research team focused on marine pollution and hazardous chemicals using marine mammals as an indica- tor species. Dr. Miyazaki organized the research project “Coastal Marine Environment” that was conducted by United Nations University, Ocean Research Institute of The University of Tokyo, and Iwate Prefecture. He worked as general coor- dinator of the Japanese Society for Promotion of Science’s Multilateral Core Univer sity Program “Coastal Marine Science” with other distinguished scientists from five Asian countries. In collabora- tion with Dr. Y. Naito, he developed an advanced Nobuyuki Miyazaki (Photo courtesy of John Anderson) data logger and camera logger, and he also estab- lished the “Bio-Logging Science” program at the University of Tokyo. Since 1990, he has conducted international ecological research of Lake Baikal in cooperation with colleagues from Russia, the United Kingdom, Belgium, Switzerland, and the United States. Dr. Miyazaki has published more than 270 English and 13 Japanese peer-reviewed papers, nine English and 51 Japanese books, and seven Eng lish and 109 Japanese reports. He also has given 316 presentations at national and inter- national conferences. 190 Miyazaki Seal Survey in Eurasian Waters in Collaboration with Russian Scientists Nobuyuki Miyazaki, Ph.D. Professor Emeritus, The University of Tokyo, Japan E-mail: [email protected] I. -
