The application of short and highly polymorphic microhaplotypes based on nonbinary-SNPs in kinship testing of extremely degraded samples
<p>Kinship testing becomes more difficult in extremely degraded samples. But commonly used genetic markers cannot completely solved this problem. Microhaplotype combining the advantages of STR and SNP may be a promising genetic marker for kinship testing in extremely degraded samples. Therefore, in this study, 36 short and highly polymorphism microhaplotype loci with length smaller than 100 bp and Ae greater than 3.0 were developed, of which 29 loci met the Hardy-Weinberg and linkage equilibrium. The CPD and CPE of these 29 loci were 0.99999999999999999999999997036 and 0.9999999945, respectively. Allele dropout of these loci was not observed in extremely degraded samples. Through simulated kinship analysis, the effectiveness of paternity testing reached 98.39% at threshold of 4/-4, and effectiveness of full-sibling testing reached 93.01% at threshold of 2/-2, which were greater than that of 15 STR loci. After combining with other 50 short and highly polymorphic microhaplotype loci, the effectiveness of half-sibling testing also reached 82.42% at the threshold of 2/-2. Our developed short and highly polymorphic microhaplotype loci may be useful for paternity testing and full-sibling testing in extremely degraded samples, and after combining with other short and highly polymorphic microhaplotype loci, may be helpful to analyze the more distant kinship relationship.</p>

Wai Gelao (Dingjiapo) kinship terms
<p>On April 23, 2013, I visited the Wai Gelao 歪仡佬 of Dingjiapo 丁家坡, Funing County, Yunnan, China. Zhang Tingjin 张庭金, 83, could only remember several kinship terms in the Wai Gelao language.</p> <p>She also reported that “big brother 大哥” in Green Gelao of Laozhai 老寨, Mabo Village 马波村 is a33 wai33.</p>
Data for: Kinship, dear enemies, and costly combat: The effects of relatedness on territorial overlap and aggression in a cooperative breeder
<p>Many species maintain territories, but the degree of overlap between territories and the level of aggression displayed in territorial conflicts can vary widely, even within species. Greater territorial overlap may occur when neighbouring territory holders are close relatives. Animals may also differentiate neighbours from strangers, with more-familiar neighbours eliciting less-aggressive responses during territorial conflicts (the "dear enemy" effect). However, research is lacking on how both kinship and overlap affect territorial conflicts, especially in group-living species.</p> <p>Here we investigate kinship, territorial overlap, and territorial conflict in a habituated wild population of group-living cooperatively breeding birds, the southern pied babbler <em>Turdoides bicolor</em>. We find that close kin neighbours are beneficial. Territories overlap more when neighbouring groups are close kin, and these larger overlaps with kin confer larger territories (an effect not seen for overlaps with unrelated groups). Overall, territorial conflict is costly, causing significant decreases in body mass, but conflicts with kin are shorter than those conducted with non-kin. Conflicts with more-familiar unrelated neighbours are also shorter, indicating these neighbours are "dear enemies". However, kinship modulates the "dear enemy" effect; even when kin are encountered less frequently, kin elicit less-aggressive responses, similar to the "dear enemy" effect. </p> <p>Kin selection appears to be a main influence on territorial behaviour in this species. Groups derive kin-selected benefits from decreased conflicts and maintain larger territories when overlapping with kin, though not when overlapping with non-kin. More generally, it is possible that kinship extends the "dear enemy" effect in animal societies.</p>

Data from: Kinship and association in a highly social apex predator population, killer whales at Marion Island
Social structure is a core element of population biology, influenced by intrinsic and environmental factors. Intra-taxon comparisons of social organization are useful in elucidating the role of such ecological determinants of sociality. Killer whales Orcinus orca are widely distributed, social delphinids with diverse morphology, diet, behaviour, and genetics, but few studies have quantitatively examined social structure in this species. We used 7 years of individual identification data on killer whales at Marion Island, Southern Ocean, to calculate the half-weight association index among 39 individuals, creating a weighted association network. There were long-term associations between individuals, though associations were dynamic over time. We defined 8 social modules using a community detection algorithm and these typically contained 3 individuals of various ages and sexes. Pairwise genetic relatedness among 20 individuals was not significantly correlated with association index. Individuals were on average more related within than between social modules, but social modules contained related as well as unrelated individuals. Likely parent pairs of 6 individuals indicated mating between social modules.
Data from: Adaptive responses and disruptive effects: how major wildfire influences kinship-based social interactions in a forest marsupial
Environmental disturbance is predicted to play a key role in the evolution of animal social behaviour. This is because disturbance affects key factors underlying social systems, such as demography, resource availability and genetic structure. However, because natural disturbances are unpredictable there is little information on their effects on social behaviour in wild populations. Here, we investigated how a major wildfire affected cooperation (sharing of hollow trees) by a hollow-dependent marsupial. We based two alternative social predictions on the impacts of fire on population density, genetic structure and resources. We predicted an adaptive social response from previous work showing that kin selection in den-sharing develops as competition for den resources increases. Thus, kin selection should occur in burnt areas because the fire caused the loss of 80% of hollow-bearing trees, but no detectable mortality. Alternatively, fire may have a disruptive social effect, whereby post-fire home range-shifts 'neutralise' fine-scale genetic structure, thereby removing opportunities for kin selection between neighbours. Both predictions occurred: the disruptive social effect in burnt habitat and the adaptive social response in adjacent unburnt habitat. The latter followed a massive demographic influx to unburnt 'refuge' habitat that increased competition for dens, leading to a density-related kin selection response. Our results show remarkable short-term plasticity of animal social behaviour and demonstrate how the social effects of disturbance extend into undisturbed habitat due to landscape-scale demographic shifts. We predicted long-term changes in kinship-based cooperative behaviour resulting from the genetic and resource impacts of forecast changes to fire regimes in these forests.
