“…Based on this finding, Andersson and Waldeck (2007) and Waldeck et al (2008) concluded that the high host-parasite relatedness among laying Eider hens is not an effect of natal philopatry alone but also forms some additional kin-biasing mechanism. This means that Eider females recognize first-order relatives (siblings, mother-daughter pairs), and possibly also maternal halfsiblings, when laying parasitically in their nests.…”

“…Using protein fingerprinting of egg albumen, Andersson and Waldeck (2007) and Waldeck et al (2008) estimated that the mean relatedness in Eiders tended to be higher among host-parasite pairs than among random pairs of spatially close neighbors. Based on this finding, Andersson and Waldeck (2007) and Waldeck et al (2008) concluded that the high host-parasite relatedness among laying Eider hens is not an effect of natal philopatry alone but also forms some additional kin-biasing mechanism.…”

We investigated the presence of kin-biased cooperative breeding in the Common Eider (Somateria m. mollissima), a colonial seaduck commonly presumed to have a high rate of natal philopatry. Based on a 23-yearlong time series of individually marked mothers and daughters, we found that on average 18% of the study population consisted of first-order relatives: mothers, daughters, and female siblings. However, there were years with no or only a few first-order kin pairs present. This was due to the overall low duckling survival in this species and the high rate of natal dispersal in this population. There was no apparent tendency for timely nesting relatives (laying within 3 days of each other) to approach each other, indicating no firm kin recognition. In a 3-year sampling of DNA from egg shell membranes, the annual rate of intraspecific brood parasitism in the population varied between 25 and 67%. However, becoming parasitized had no effect on the subsequent choice of brood tending tactics, i.e., whether to tend alone or communally. Neither was the choice of brood tending tactics affected by the number of own eggs in the clutch or by the female body condition. However, becoming a communal brood-tender was jointly contributed by the presence of alien eggs in the nest and the presence of first-order kin in the colony during early breeding. The greatest effect on females favoring communal brood care instead of rearing alone was due to the number of similar-aged broods nearby at the time of nest exodus. We found no evidence of firm kin recognition among individuals in our study population. ZusammenfassungVerwandtschaftsstruktur und Brutpflegetaktik in einer Population der Europäischen Eiderente (Somateria m. mollissima)Wir haben das Auftreten von verwandtschaftsbasiertem kooperativem Brüten bei der Europäischen Eiderente (Somateria m. mollissima) untersucht, einer koloniebrütenden Meerente, bei der im Allgemeinen eine ausgeprägte Geburtsortstreue angenommen wird. Basierend auf einer 23 Jahre währenden Zeitreihe individuell markierter Mütter und Töchter fanden wir, dass durchschnittlich 18% der untersuchten Population aus Verwandten ersten Grades bestanden: Müttern, Töchtern und Schwestern. Es gab jedoch Jahre, in denen nur wenige Verwandtschaftspaare ersten Grades anwesend waren. Dies war auf die insgesamt niedrige Ü berlebensrate der Entenküken bei dieser Art und die hohe Rate der Abwanderung vom Geburtsort in dieser Population zurückzuführen. Verwandte, die innerhalb von drei Tagen mit der Eiablage begannen, zeigten keine offensichtliche Tendenz, sich einander zu nähern, was darauf hindeutet, dass Verwandte nicht sicher erkannt werden. Die Entnahme von DNA-Proben aus der Eischalenmembran über einen Zeitraum von drei Jahren zeigte, dass die jährliche Rate von intraspezifischem Brutparasitismus in der Population zwischen 25 und 67% variierte. Ob ein Nest parasitiert wurde oder nicht, hatte jedoch keinen Einfluss darauf, ob Communicated by P

“…This general Wnding has important implications for the study of Wne-scale genetic structure, patterns of inbreeding and social interactions between kin (Lessells et al 1994;MacColl et al 2000;Ronce et al 2000;Van de Casteele and Matthysen 2006;Waldeck et al 2008). If parents return to the same family-rearing areas in subsequent years (Drent 1984;Nack and Andersen 2006) this pattern may even be reinforced by increased proximity between oVspring from diVerent families.…”

Family movements before independence influence natal dispersal in a territorial songbird

2009

Dispersal behaviour in territorial species is typically assumed to be independent of parental behaviour except for the possible role of parental eviction from the natal territory. Great tits defend exclusive territories at the onset of breeding but after fledging undertake substantial excursions with dependent offspring, sometimes covering distances equivalent to ten or more breeding territories and even moving across open spaces into neighbouring woodlots. We show that postfledging family movements are significantly associated with subsequent dispersal directions of recruits by comparing observed angles of movement with a simulated distribution taking into account the patchy nature of the landscape. However, the extent of family movements did not predict dispersal distances. Our findings provide an explanation for previously observed similarities in dispersal direction between siblings in the same study population, as well as for effects of nest site location on dispersal. More generally we show the existence of a novel mechanism for parents to influence dispersal and fine-scale kinship structure among their offspring.

“…Consequently, the simulation is forced to start at a specific location, but can then move according to the set conditions in the given space. In the real world however, this is not always useful: when studying, for example, migration patterns (Codling et al 2010), nest borrowing (Waldeck et al 2008), or fusion of high and low frequency GPS points, the ability to specify an ending point can be crucial. Technitis et al (2015) introduced the Random Trajectory Generator (RTG), an algorithm that enables the user to create randomly varying, possible trajectories between endpoints, based on principles of Time Geography.…”

An Algorithm for Empirically Informed Random Trajectory Generation Between Two Endpoints

We present a method to create empirically informed, and thus realistic, random trajectories between two endpoints. The method used relies on empirical distribution functions, which define a dynamic drift expressed in a stepwise joint probability surface. We create random discrete time-step trajectories that connect spatiotemporal points while maintaining a predefined geometry, often based on real observed trajectories. The resulting trajectories have multiple uses, such as to generate null models for hypotheses testing, to serve as a basis for resource selection models, through the integration of spatial context and to quantify space use intensity.
