Guarantee of financial support for student James Savage, signed by William Tudor and John Cooper, 1799 July 25

This legal agreement, a guarantee of financial support for entering student James Savage (A.B. 1803), was signed on July 25, 1799 by his two guarantors, William Tudor and John Cooper. The document was also signed by two witnesses, William Tudor's sons John Henry Tudor and Frederic Tudor. The agreement specifies that, in the event of Savage's failure to settle all financial obligations to the President and Fellows of Harvard College during the course of his studies, the two guarantors would be responsible for a payment of two hundred ounces of silver. It seems that the Tudors and Cooper were relatives of Savage, thus explaining their desire to assure his entry to Harvard by entering into this financial obligation.

Letter from Daniel Upton to James Savage, 1799 September 29

Daniel Upton wrote this letter from Machias, Maine on September 29, 1799; it is addressed to James Savage, who was then a freshman at Harvard College. In the letter, Upton advises Savage to study ardently, avoiding the temptation to procrastinate. He thanks Savage for having sent him a copy of "Mr. Lowell's oration" and sends greetings to a Mr. Holbrook and Mr. Jones. He also passes along the fond wishes of those in Machias who know Savage, including John Cooper and his wife, Phineas Bruce and his wife, and Hannah Bruce (Upton's future wife). Upton explains that he is writing the letter in a hurry because he is sending it on board with Captain Merryman, who is about to set sail, presumably for Boston.

Building genetic networks using relatedness information : a novel approach for the estimation of dispersal and characterization of group structure in social animals

Natal dispersal is an important life history trait driving variation in individual fitness, and therefore, a proper understanding of the factors underlying dispersal behaviour is critical to many fields including population dynamics, behavioural ecology and conservation biology. However, individual dispersal patterns remain difficult to quantify despite many years of research using direct and indirect methods. Here, we quantify dispersal in a single intensively studied population of the cooperatively breeding chestnut-crowned babbler (Pomatostomus ruficeps) using genetic networks created from the combination of pairwise relatedness data and social networking methods and compare this to dispersal estimates from re-sighting data. This novel approach not only identifies movements between social groups within our study sites but also provides an estimation of immigration rates of individuals originating outside the study site. Both genetic and re-sighting data indicated that dispersal was strongly female biased, but the magnitude of dispersal estimates was much greater using genetic data. This suggests that many previous studies relying on mark–recapture data may have significantly underestimated dispersal. An analysis of spatial genetic structure within the sampled population also supports the idea that females are more dispersive, with females having no structure beyond the bounds of their own social group, while male genetic structure expands for 750 m from their social group. Although the genetic network approach we have used is an excellent tool for visualizing the social and genetic microstructure of social animals and identifying dispersers, our results also indicate the importance of applying them in parallel with behavioural and life history data.

Unrelated helpers neither signal contributions nor suffer retribution in chestnut-crowed babblers

Alloparental care by distant/nonkin that accrue few kin-selected benefits requires direct fitness benefits to evolve. The pay-to-stay hypothesis, under which helpers contribute to alloparental care to avoid being expelled from the group by dominant individuals, offers one such explanation. Here, we investigated 2 key predictions derived from the pay-to-stay hypothesis using the chestnut-crowed babbler, Pomatostomus ruficeps, a cooperatively breeding bird where helping by distant/nonkin is common (18% of nonbreeding helpers). First, we found no indication that distant or nonkin male helpers advertised their contributions toward the primary male breeder. Helpers unrelated to both breeders were unresponsive to provisioning rates of the dominant male, whereas helpers that were related to either the breeding male or to both members of the pair were responsive. In addition, unrelated male helpers did not advertise their contributions to provisioning by disproportionately synchronizing their provisioning events with those of the primary male breeder or by provisioning nestlings immediately after him. Second, no helper, irrespective of its relatedness to the dominant breeders, received aggression when released back into the group following temporary removal for 1-2 days. We therefore find no compelling support for the hypothesis that pay-to-stay mechanisms account for the cooperative behavior of unrelated males in chestnut-crowned babblers.
