Three different approaches were used to assess the kinship structure of two epiphytic bryophytes, Orthotrichum speciosum and O. obtusifolium, that have different dispersal strategies. The two species were sampled in a 200 ha landscape where species occurrence and host trees had been mapped previously. Local environmental conditions at sampled trees were recorded and kinship between individuals ...

10 Maloney and Dal Martello (2006) reported that similarity ratings of pairs of related and unrelated children were almost perfect predictors of the probability that those children were labeled as being siblings by a second group of observers. Surprisingly, similarity ratings were not good predictors of whether a sibling pair was same-sex or opposite-sex or how close a pair was in age, suggesti...

—This paper explores new roles that traditionally rural kinship networks organized around the marriage institution might play in improving labor market outcomes in urban Africa. Using new data from Kisumu, Kenya, and controlling for selection into marriage, we find that marriage significantly increases employment levels and incomes in our sample of migrants. At the same time, marriage increases...

Research on industrial clusters has shifted in a paradigmatic way from an exploration of structural ideal-types toward evolutionary explanations. Thus far, however, networks – the key concept in the former paradigm – and evolution – the focus in the latter – remain somewhat unconnected in the literature. This article addresses this gap by developing a comprehensive tri-polar analytical framewor...

Relatedness is a cornerstone of the evolution of social behavior. In the human lineage, the existence of cooperative kin networks was likely a critical stepping stone in the evolution of modern social complexity. Here we report the results of the first experimental manipulation of a putative cue of human kinship (facial self-resemblance) among ostensible players in a variant of the “tragedy of ...

UNLABELLED Two functions for pedigree-drawing available in R (http://www.r-project.org): plot.pedigree in kinship and pedtodot in gap are described. The latter requires graphviz (http://www.graphviz.org). They can produce many pedigree diagrams quickly into a single file, serving as alternatives to programs that only offer interactive use. AVAILABILITY Packages kinship and gap are available f...
