- Regional and seasonal flight speeds of soaring migrants and the role of weather conditions at hourly and daily scales (2015, background): “While the general timing of migration may in part be endogenously controlled in response to day length (Gwinner and Helm 2003, Visser et al. 2010), general climatic conditions also influence timing of migration (Shamoun-Baranes et al. 2010).”
- Climatic effects on timing of spring migration and breeding in a long‐distance migrant, the pied flycatcher Ficedula hypoleuca (2005, unknown): “One constraint in advancing spring arrival may be the lack of genetic variation in the birds’ spring arrival date, which depends mainly on photoperiodic cues at the wintering grounds (Gwinner 1996, Gwinner and Helm 2003).”
- Bird migration in the southern hemisphere: a review comparing continents (2008, background): “Thus with respect to endogenous control and orientation, these southern hemisphere migrants display mechanisms similar to northern hemisphere species, especially those travelling from Europe to Africa (Gwinner and Helm 2003).”
- What decision rules might pink-footed geese use to depart on migration? An individual-based model (2009, background): “An extensive literature shows that many migratory birds arrive every year at a fixed date, using endogenous rhythms under photoperiod control (Gwinner and Helm 2003; Newton 2008).”
- A framework for the study of genetic variation in migratory behaviour (2006, unknown): “…to arise from direct influences of local environmental conditions, but also to be a consequence of different reaction norms to the environmental cues used to synchronise the annual cycle with seasonal fluctuations in resource availability (Widmer 1999; Gwinner and Helm 2003; Helm et al. 2005).”
- Travelling to breed (2006, background): “Given the limited scale of reaction measured in days of advancement there must be additional timing factors involved, and it is but a short step to implicate the endogenous circannual rhythmicity well documented for birds by Gwinner and coworkers (Gwinner and Helm 2003).”
- Vertebrate road-kill patterns in Mediterranean habitats: Who, when and where (2015, background): “With the aim to control for species phenology we also included the photoperiod variation, a variable potentially affecting seasonal behaviors (directly or indirectly) and consequently the abundance or activity variations of a large number of species (Fryxell and Sinclair, 1988; Gwinner and Helm, 200”
- Climate change and timing of avian breeding and migration throughout Europe (2007, background): “…hypoleuca · Sturnus vulgaris Resale or republication not permitted without written consent of the publisher Clim Res 35: 93–105, 2007 mechanisms based on circannual clocks, which are synchronised with day length variation during a particular part of the year (Gwinner 1996, Gwinner & Helm 2003).”
- How Migrants Get There: Migratory Performance and Orientation (2007, background): “One answer to this problem is to rely on an inherited endogenous program that encodes both direction and distance to migrate (for a review, see Gwinner and Helm 2003), as well as the amount of energy needed for longer nonstop flights.”
- Animal migration: is there a common migratory syndrome? (2006, background): “Hormonal involvement is complex and interacts with other aspects of particular physiologies such as circannual rhythms in birds (Gwinner and Helm 2003).”
