Extended safe havens and between-group dispersal of helpers in a cooperatively breeding cichlid
In cooperative breeders, between-group dispersal of helpers is expected to occur if it increases their fitness. Genetic data suggest that helpers in the cooperatively breeding Lake Tanganyika cichlid Neolamprologus pulcher occasionally migrate into nearby groups where they again become helpers. We studied in the field how and why helpers migrate between groups by recording their ranging and soc...
متن کاملPaying to stay or paying to breed? Field evidence for direct benefits of helping behavior in a cooperatively breeding fish
Several hypotheses aim to explain the evolution of helping behavior, but conclusive experimental support for evaluating the relative importance of individual hypotheses is still larking We report on two field experiments* conducted to test the "territory inheritance" and "pay-to-stay" hypotheses in the cooperatively breeding cichlid fish Neolamprologus pulcher. The territory inheritance hypothe...
متن کاملCichlids do not adjust reproductive skew to the availability of independent breeding options
Helpers in cooperatively breeding species forego all or part of their reproduction when remaining at home and assisting breeders to raise offspring. Different models of reproductive skew generate alternative predictions about the share of reproduction unrelated subordinates will get depending on the degree of ecological constraints. Concession models predict a larger share when independent bree...
متن کاملHelpers increase daily survival rate of Southern Lapwing (Vanellus chilensis) nests during the incubation stage
Cooperative breeding is characterized by reproduction in the presence of helpers. The impact that these helpers have on the reproductive success of group members is one of the long-standing questions in cooperative breeding literature. In several cooperative species, helpers are known to provide benefits during different stages of the reproductive cycle. The aim of this study was to investigate...
متن کاملA Novel Collaboration Partner Model Based on the Personal Relationships of SNS
In this paper, we describe a novel model for locating appropriate ‘helpers’ for users based on the Chain of Friends (CoF) personal relationship in a SNS system, in order to locate appropriate ‘helpers’ for different users. This model is called SESNMM (Search Engine for Social Networked Mobile Model) and allows individual users, located in remote locations, to participate in a collaborative onli...
