| Title | The social brain hypothesis | Type | Journal Article | ||

1998 | Publication | Evolutionary Anthropology: Issues, News, and Reviews | Abbreviated Journal | Evol. Anthropol. |

| Keywords | brain size – neocortex – social brain hypothesis – social skills – mind reading – primates | ||||
| Abstract | Conventional wisdom over the past 160 years in the cognitive and neurosciences has assumed that brains evolved to process factual information about the world. Most attention has therefore been focused on such features as pattern recognition, color vision, and speech perception. By extension, it was assumed that brains evolved to deal with essentially ecological problem-solving tasks. © 1998 Wiley-Liss, Inc. | ||||

| Notes | Robin Dunbar is Professor of Evolutionary Psychology and Behavioural Ecology at the University of Liverpool, England. His research primarily focuses on the behavioral ecology of ungulates and human and nonhuman primates, and on the cognitive mechanisms and brain components that underpin the decisions that animals make. He runs a large research group, with graduate students working on many different species on four continents. | Approved | no | ||

| Title | Mucosal antibodies can be measured in air-dried samples of saliva and feces | Type | Journal Article | ||
| Year |
1998 | Publication | Journal of Immunological Methods | Abbreviated Journal | |
| Volume | 215 | Issue | 1–2 | Pages | 163-172 |
| Keywords | Saliva; Feces; IgA; IgG; Air-drying | ||||
| Abstract | IgA antibodies reflecting airways or intestinal mucosal immune responses can be found in saliva and feces, respectively, and IgG antibodies reflecting serum antibodies can be found in saliva. In this study, antibodies were detected in samples of saliva and feces which had been air-dried at room temperature (+20°C) or +37°C, and stored at these temperatures for up to 6 months. In saliva the antibody levels increased, while the antibodies in feces decreased upon storage. The individual IgA antibody concentrations which were adjusted by using the ratios of specific IgA/total IgA were relatively stable in both saliva and feces, and correlated with corresponding antibody levels in samples which had been stored at -20°C. The results indicate that air-dried saliva and feces can be used for semiquantitative measurements of mucosal antibodies, even after prolonged storage at high temperatures and lack of refrigeration. | ||||

| Title | Discrimination learning in the white rhinoceros | Type | Journal Article | ||
| Year |
1998 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |
| Volume | 58 | Issue | 1–2 | Pages | 197-202 |
| Keywords | Rhinoceros; Learning | ||||
| Abstract | This study examined the ability of two adult white rhinoceroses (Ceratotherium simum simum) to develop a visual discrimination between an open circle and a triangle. These stimuli were presented as black symbols on large white cards. The cards were presented 4.6 m apart and a food reward was given if the subject approached the open circle. Ten discrimination choices were given daily until each subject reached the criterion of 80% correct responding over a block of 50 trials. The female reached the criterion over trials 151–200, while the male required considerably longer (trials 501–550). The male's discrimination was dramatically affected by a shift in the food reward. This study demonstrates that these rhinos were able to develop a successful discrimination and this protocol could be used to further examine their visual acuity. | ||||

Tierpsychol., 44, 323-331 (1977), ISSN 0044-3573/ASTM-Coden: ZETIAG.1 Abstract African and Asiatic Wild Asses (Equus africanus and Equus hemionus) live in unstable groups or herds of variable composition. Some of the adult stallions are territorial in large territories in which they tolerate other ♂♂. The territorial ♂♂ are dominant over all their conspecifics |
