Between‐patch natal dispersal declines with increasing natal patch size and distance to other patches in the endangered Southern Dunlin Calidris alpina schinzii

Abstract: Sweden 5 Ljungv€ agen 3, V€ ar€ obacka, 430 22, Sweden Natal dispersal has profound consequences for populations through the movement of individuals and genes. Habitat fragmentation reduces structural connectivity by decreasing patch size and increasing isolation, but understanding of how this impacts dispersal and the functional connectivity of landscapes is limited because many studies are constrained by the size of the study areas or sample sizes to accurately capture natal dispersal. We quantified natal di… Show more

“…Each year fieldwork began in late April with searching for territories and resighting of birds, and continued until mid-July with searching for nests and broods. Fieldwork enabled us to effectively record the majority of adults and to follow their reproductive success (Pakanen et al 2011(Pakanen et al , 2017a. Adults were captured with mist-nets or cage traps while brooding chicks or incubating eggs.…”

“…1 Location of the breeding sites of Southern Dunlin on the west coast of Sweden (1 = Ödsmåls kile, 2 = Torkelstorp, 3 = Tjolöholm, 4 = Ölmevalla, 5 = Båtafjorden, 6 = Klosterfjorden, 7 = Getterön). See Pakanen et al (2017) for further details on the sites; note that the breeding sites Klosterfjorden and Getterön were excluded from the analyses presented here due to insufficient data on brood survival…”

“…The study population is isolated from other populations with the nearest breeding population being about 300 km away from our study population in the province of Scania, SW Sweden (Blomqvist et al 2010). Due to the isolation from other populations, and because all known breeding sites are monitored regularly, and dispersal between the sites is rare and controlled for, we were able to reliably estimate local recruitment (Pakanen et al 2017).…”

“…This could be the kind of difficult environmental conditions in which birds carrying geolocators incur more costs. Permanent emigration outside our study area is an unlikely explanation because there is little breeding habitat elsewhere within the Bothnian Bay area (Pakanen et al 2017), which is one of the advantages of studying survival in this population.…”

“…Due to lack of suitable breeding habitats, this population is confined to these clearly defined habitat patches and the closest populations are 400 km away. Therefore, extensive studies of this colour-ringed population allow detailed monitoring of movement and, by recording annual resightings, reliable examination of survival (see Pakanen et al 2016Pakanen et al , 2017 for more details on field methods).…”
