Carry-Over or Compensation? The Impact of Winter Harshness and Post-Winter Body Condition on Spring-Fattening in a Migratory Goose Species
Clausen, Kevin K.; Madsen, Jesper; Tombre, Ingunn (Journal article, 2015)Environmental conditions at one point of the annual cycle of migratory species may lead to cross-seasonal effects affecting fitness in subsequent seasons. Based on a long-term mark-resighting dataset and scoring of body ... -
Combining modelling tools to evaluate a goose management scheme
Baveco, Johannes M.; Bergjord, Anne-Kari; Bjerke, Jarle W.; Chudzinska, Magda E.; Pellissier, Loïc; Simonsen, Caroline E.; Madsen, Jesper; Tombre, Ingunn; Nolet, Bart A. (Journal article; Peer reviewed, 2017)Many goose species feed on agricultural land, and with growing goose numbers, conflicts with agriculture are increasing. One possible solution is to designate refuge areas where farmers are paid to leave geese undisturbed. ... -
Could Have Gone Wrong: Effects of Abrupt Changes in Migratory Behaviour on Harvest in a Waterbird Population
Madsen, Jesper; Christensen, Thomas Kjær; Balsby, Thorsten J. S.; Tombre, Ingunn (Journal article; Peer reviewed, 2015)To sustainably exploit a population, it is crucial to understand and reduce uncertainties about population processes and effects of harvest. In migratory species, management is challenged by geographically separated changing ... -
Environmental factors affecting numbers of pink-footed geese Anser brachyrhynchus utilising an autumn stopover site
Jensen, Gitte Høj; Tombre, Ingunn; Madsen, Jesper (Journal article; Peer reviewed, 2016)NorwayFor huntable waterbird species, the autumn migration strategy may be important for their fitness, as their behaviour and environmental factors may influence their exposure to hunting mortality. Hunting activity may ... -
Goose management schemes to resolve conflicts with agriculture:Theory, practice and effects
Eythórsson, Einar; Tombre, Ingunn; Madsen, Jesper (Journal article; Peer reviewed, 2017)In 2012, the four countries hosting the Svalbard population of pink-footed goose Anser brachyrhynchus along its flyway launched an International Species Management Plan for the population. One of the aims was to reduce ... -
Hunting migratory geese: is there an optimal practice?
Jensen, Gitte Høj; Madsen, Jesper; Tombre, Ingunn (Journal article; Peer reviewed, 2016)Since the mid-20th century, many European and North American goose populations have increased dramatically in numbers, causing conflict with agricultural interests in their staging and wintering areas. In some cases, to ... -
Implementation of the first adaptive management plan for a European migratory waterbird population: The case of the Svalbard pink-footed goose Anser brachyrhynchus
Madsen, Jesper; Williams, James Henty; Johnson, Fred A.; Tombre, Ingunn; Dereliev, Sergey; Kuijken, Eckhart (Journal article; Peer reviewed, 2017)An International Species Management Plan for the Svalbard population of the pink-footed goose was adopted under theAgreement on theConservation of African-Eurasian Migratory Waterbirds in 2012, the first case of adaptive ... -
Is it worthwhile scaring geese to alleviate damage to crops? – An experimental study
Simonsen, Caroline Ernberg; Madsen, Jesper; Tombre, Ingunn; Nabe-Nielsen, Jacob (Journal article; Peer reviewed, 2015)Summary 1.Increasing population sizes of geese are the cause of numerous agricultural conflicts in many regions of the Northern Hemisphere. Scaring is often used as a tool to chase geese away from fields, either as a means ... -
Landscape selection by migratory geese: Implications for hunting organisation
Jensen, Gitte Høj; Pellissier, Loïc; Tombre, Ingunn; Madsen, Jesper (Journal article; Peer reviewed, 2017)Over the last decades, many wild goose populations have increased significantly and are now causing conflicts with socioeconomic and biological interests. To mitigate impacts of rapid population increases, population control ... -
Late snow melt moderates herbivore disturbance of the Arctic tundra
Anderson, Helen B.; Speed, James David Mervyn; Madsen, Jesper; Pedersen, Åshild Ønvik; Tombre, Ingunn; van der Wal, René (Journal article; Peer reviewed, 2016)Resilience of tundra vegetation to disturbance by herbivores can be low and lead to ecosystem state shifts. Pink-footed geese Anser brachyrhynchus are the most numerous herbivore on Svalbard and disturb vegetation when ... -
Linking public participation in scientific research to the indicators and needs of international environmental agreements
Danielsen, Finn; Pirhofer-Walzl, Karin; Adrian, Teis P.; Kapijimpanga, Daniel R.; Burgess, Neil D.; Jensen, Per M.; Bonney, Rick; Funder, Mikkel; Landa, Arild Magne; Levermann, Nette; Madsen, Jesper (Peer reviewed; Journal article, 2014)Different monitoring approaches collect data that can measure progress toward achieving global environmental indicators. These indicators can: (1) Audit management actions; (2) Inform policy choices; and (3) Raise awareness ... -
Scaring as a tool to alleviate crop damage by geese: Revealing differences between farmers’ perceptions and the scale of the problem
Simonsen, Caroline; Tombre, Ingunn; Madsen, Jesper (Journal article; Peer reviewed, 2017)Expanding populations of farmland foraging geese are causing escalating conflict with agriculture. We used questionnaires to investigate farmers´ perceptions in mid-Norway of spring staging geese and the extent to which ... -
Spatio–temporal distribution of greylag goose Anser anser resightings on the north-west/south-west European flyway: guidance for the delineation of transboundary management units
Bacon, Léo; Madsen, Jesper; Jensen, Gitte Høj; de Vries, Lisenka; Follestad, Arne; Koffijberg, Kees; Kruckenberg, Helmut; Loonen, Maarten; Månsson, Johan; Nilsson, Leif; Voslamber, Berend; Guillemain, Matthieu (Journal article; Peer reviewed, 2019)In western Europe, the majority of wild goose populations have increased exponentially over the last decades. Such increase is the source of many socio–ecological conflicts. The need for coordinated management actions to ... -
Time series analysis reveals synchrony and asynchrony between conflict management effort and increasing large grazing bird populations in northern Europe
