The comparisons involved two aspects: taxonomic (differences among species within tribes and differences among tribes) and ecological (diet composition: vegetation, invertebrates, or fish and the foraging mode: browsing, dabbling, shallow diving, and deep diving). The relative size of the encephalon (E) and its parts (optic tectum, OT; cerebellum, C; brain stem, BS; hemispheres, H) were described using appropriate indices. Five of them, called the cerebral-body indices (E\/BW, OT\/BW, C\/BW, BS\/BW, H\/BW), involved a ratio between the weight of E or its parts and that of the body (BW). Four intracerebral indices (OT\/E, C\/E, BS\/E, H\/E) and allometric equations were used as well. Almost all the indices showed a high intraspecific variability within the Anserini and Mergini; on the other hand, the intracerebral indices did not differ between the species of the Anatini and Aythyini (except for OT\/E in the Aythyini). Between-tribe differences were reflected in all 9 indices. The birds feeding on different diets were found to differ in their OT\/E and H\/E. The herbivorous anserifom OT\/E was clearly lower than that of those birds feeding on invertebrates and fish. The highest OT\/E was that of the piscivorous birds. In terms of foraging mode, significant differences were revealed in 7 out of the 9 indices used (differences in OT\/BW and C\/BW proved non-significant). OT\/E of the browsing birds was clearly lower than that of the deep diving ducks; BS\/E of the browsers was much lower than that of the dabbling and shallow diving ducks. Geese and swans (browsers) showed much higher H\/E compared to the deep diving sea ducks. The latter revealed the highest C\/E, but significant differences were detected only in comparison with C\/E of the shallow diving ducks. The taxonomic (among tribes) and ecological comparisons showed more differences in the intracerebral indices than in the cerebral-body indices.<\/jats:p>","DOI":"10.1159\/000084315","type":"journal-article","created":{"date-parts":[[2005,3,11]],"date-time":"2005-03-11T10:14:42Z","timestamp":1110536082000},"page":"244-261","source":"Crossref","is-referenced-by-count":15,"title":["Anseriform Brain and Its Parts versus Taxonomic and Ecological Categories"],"prefix":"10.1159","volume":"65","author":[{"given":"El\u017cbieta","family":"Kalisi\u0144ska","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2005,4,15]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1159%2F000006598"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1159%2F000113243"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1159%2F000118782"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1159%2F000143668"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1159%2F000113235"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1469-7998.1985.tb04920.x"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1469-7998.1985.tb04946.x"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1098%2Frspb.2003.2413"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1098%2Frspb.1993.0129"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00709377"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1159%2F000113557"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1439-0469.1984.tb00652.x"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00338056"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1126%2Fscience.2196673"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.2307%2F2409412"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1098%2Frspb.1992.0068"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1159%2F000113239"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1159%2F000047228"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1439-0264.1997.tb00097.x"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1073%2Fpnas.86.4.1388"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1163%2F156853902320387918"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1159%2F000076784"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.2307%2F1368999"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1038%2F293057a0"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1017%2FS095283690100036X"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00318396"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1159%2F000114353"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.1159%2F000114349"},{"key":"ref29","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00315637"},{"key":"ref30","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00347023"},{"key":"ref31","doi-asserted-by":"publisher","DOI":"10.1159%2F000116581"},{"key":"ref32","doi-asserted-by":"publisher","DOI":"10.1002%2Fcne.901640403"},{"key":"ref33","doi-asserted-by":"publisher","DOI":"10.1079%2FPNS19940062"},{"key":"ref34","doi-asserted-by":"publisher","DOI":"10.1002%2Fneu.480270103"},{"key":"ref35","doi-asserted-by":"publisher","DOI":"10.1159%2F000047204"}],"container-title":["Brain, Behavior and Evolution"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/84315","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/84315","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:42:10Z","timestamp":1745466130000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000084315"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2005]]},"references-count":35,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2005,4,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000084315","archive":["Portico"],"relation":{},"ISSN":["0006-8977","1421-9743"],"issn-type":[{"value":"0006-8977","type":"print"},{"value":"1421-9743","type":"electronic"}],"subject":[],"published":{"date-parts":[[2005]]}}}
