Annual survival and breeding dispersal of a seabird adapted to a stable environment: implications for conservation

Abstract: Understanding the spatial dynamics of populations is essential for conservation of species at the landscape level. Species that have adapted to stable environments may not move from their breeding areas even if these have become sub-optimal due to anthropogenic disturbances. Instead, they may breed unsuccessfully or choose not to breed at all. Damara Terns Sternula balaenarum feed off the highly productive Benguela Upwelling System. They breed on the coastal desert mainland of Namibia where development and off… Show more

“…However, as marsh terns depend on unpredictable breeding habitats (inland marches, fish ponds, flooded meadows), they should exhibit a higher degree of nomadism/emigration than 'non-marsh terns' and, consequently, a lower survival rate (Robinson and Oring 1997;Braby et al 2012). Our data show-as do data of other studies-that an unpredictable breeding habitat yields low breeding site fidelity (Robinson and Oring 1997;Southern and Southern 1982).…”

“…Philopatry also tends to be higher in large, stable colonies than small colonies and/or colonies in less stable habitat (Austin, 1949;McNicholl, 1975;Renken and Smith, 1995;Sánchez et al, 2004;Dittmann et al, 2007;Ratcliffe et al, 2008;Braby et al, 2012). Because most research has focused on large, stable colony sites, an additional upward bias in estimates of philopatry exists.…”
