Imitation and Traditions in Wild Banded Mongooses
Evidence has accumulated in recent years indicating that traditions are not a unique feature of human societies but may be common in primates and some other mammals. However, most documented cases remain contentious because observational studies of free-living animals suffer from interpretive weaknesses, whereas social diffusion experiments performed in captivity may not reflect conditions foun...
متن کاملCauses and consequences of intergroup conflict in cooperative banded mongooses
http://dx.doi.org/10.1016/j.anbehav.2017.01.017 0003-3472/© 2017 The Authors. Published by Elsevier (http://creativecommons.org/licenses/by/4.0/). Conflict between groups is a notable feature of many animal societies. Recent theoretical models suggest that violent intergroup conflict can shape patterns of within-group cooperation. However, despite its prevalence in social species, the adaptive ...
متن کاملReproductive competition triggers mass eviction in cooperative banded mongooses.
In many vertebrate societies, forced eviction of group members is an important determinant of population structure, but little is known about what triggers eviction. Three main explanations are: (i) the reproductive competition hypothesis, (ii) the coercion of cooperation hypothesis, and (iii) the adaptive forced dispersal hypothesis. The last hypothesis proposes that dominant individuals use e...
متن کاملBehaviour: Begging Is a Joint Effort in Banded Mongooses
Lack of competition for food items in banded mongoose litters allows pups to benefit from more demanding siblings, suggesting that in this species begging may not be entirely selfish.
متن کاملGroups of banded matrices with banded inverses
AproductADF1 : : : FN of invertible block-diagonalmatrices will be bandedwith a banded inverse. We establish this factorization with the numberN controlled by the bandwidthsw and not by the matrix size n:When A is an orthogonal matrix, or a permutation, or banded plus finite rank, the factors Fi have w D 1 and generate that corresponding group. In the case of infinite matrices, conjectures rema...
