  • Att lära sig laga mat – en del av hem- och konsumentkunskapens didaktik
  • 2013
  • swepub:Mat_conferencepaper_t (swepub:level_scientificother_t)abstract
    • Det obligatoriska ämnet hem- och konsumentkunskap (hkk) syftar till att elever ska utveckla kunskaper och intresse för hushållets verksamheter. På grundsärskolan i Sverige har elever med lindrig utvecklingsstörning tre gånger så mycket hkk som elever i grundskolan. Den här studien fokuserar på ämnesdidaktik i hkk på grundsärskolan. Mat, måltider och hälsa är ett centralt innehåll i hkk och innefattar hur man lagar mat genom val av matlagningsmetoder, recept, ingredienser och redskap. Att lära sig laga mat har historiskt sett skett genom att man har varit tillsammans med de som behärskar kunskapen och sedan tagit efter. Att kunna laga mat kan ses som kunskaper för livet och kan bidra till mer hälsosamma matvanor. Att förstå hur elever lär sig matlagning är därför något centralt för att utveckla en ämnesdidaktik inom hkk. Syftet med studien är att undersöka och diskutera vilka artefakter som elever möter och använder sig av när de lär sig matlagning i hkk-undervisning. Teoretisk utgångspunkt är sociokulturell teori med särskilt fokus på elevers användning av artefakter. Metoden är deltagande observation. Resultatet visar att elever i de undersökta grupperna har stora svårigheter att använda recept för att lära sig laga mat, ändå är recept något som lärare måste förhålla sig till enligt kursplanen. Hur kan praktiskt kunnande likt matlagning läras ut? Är receptet som instruktion en didaktisk omöjlighet? De spörsmål som studien ger upphov till rör inte enkom elever med särskilda behov, utan förmodligen många andra som behöver lära sig matlagning. Vad kan vara problemet med att göra deltagande observationer i en studie som denna? Vilka likheter och skillnader kan man tala om när det gäller ämnesdidaktik i teoretiska respektive praktiska ämnen?

  • Litteraturläsning i förskolan
  • 2013
  • swepub:Mat_book_t (swepub:level_scientificother_t)abstract
    • Tidiga textmöten hjälper barn att utveckla strategier i sin senare läsning och ger dem en inre motivation att söka läsupplevelser och kunskap om omvärlden. Den tidiga läsningen sätter på så vis spår i den fortsatta litteratur- och språkutvecklingen, men också i kunskapsutvecklingen i stort. Men hur arbetar förskolepersonal med uppdraget att grundmura nyfikenhet och lust till läsning? Och hur kan litteraturläsningens potential som kunskapskälla tas tillvara? I bokens första del undersöker författarna vilka förutsättningar barnen ges vid ett antal förskolor i Sverige att utveckla kunskap med litteraturens hjälp. I den andra delen resonerar de kring tematiskt arbete i förskolan och vilken funktion läsning av skönlitteratur kan ha i sådana sammanhang. Men de ger även konkreta planeringsförslag på teman – teman om familjekonstellationer och om natur, djur och miljö – där ett uttalat syfte med litteraturläsningen är just att stödja barnens kunskapsutveckling. Litteraturläsning i förskolan vänder sig främst till blivande och yrkesverksamma förskollärare. Den erbjuder också värdefull läsning för bibliotekarier som samarbetar med förskolan.

  • Innate responses of mallard ducklings towards aerial, aquatic and terrestrial predators
  • 2012
  • record:In_t: Behaviour. - Leiden, Netherlands : Brill Academic Publishers. - 0005-7959 .- 1568-539X. ; 149:13-14, s. 1299-1317

    • Reproductive success in ducks is strongly influenced by predation on the breeding grounds. Ducklings are targeted by a range of terrestrial, aerial and aquatic predators, giving a strong selective advantage to individuals and broods that have effective ways to avoid predation. In experiments on naive mallard (Anas platyrhynchos) ducklings without an accompanying adult female we investigated the innate ability to identify and avoid threats at varying intensity from aerial, aquatic and terrestrial predators. Ducklings displayed increased vigilance in response to pre-recorded calls of predatory birds, representing a low level of threat. They did not react to visual and olfactory stimuli generated by motionless northern pike (Esox lucius). Neither did they show a strong response to caged American mink (Neovison vison) (visual and olfactory stimuli), although they avoided the area with the mink, indicating a certain level of recognition. High intensity threats were simulated by staging attacks from aerial (goshawk, Accipiter gentilis) and aquatic predators (northern pike). The aerial attack made ducklings dive and scatter under water, whereas the response to attack by pike was to run on the water and scatter in different directions. The lack of response to a ‘passive’ pike and the rather weak avoidance of mink indicate that olfactory cues are not as important in identifying a potential predatory threat by ducklings as are auditory cues. Visual cues appear to be of little importance unless they are combined with movement, and a clear response is only triggered when the intensity of predator threat is high. Mallard ducklings, thus, show an innate capacity to adjust anti-predator behaviour to different predator types and to threat intensity. Our study highlights the general trade-off between foraging needs and predator avoidance, but also second-order trade-offs in which innate avoidance behaviour towards one type of predator may increase predation risk from another.

  • Pike predation affects breeding success and habitat selection of ducks
  • 2011

    • 1. Fish and ducks often belong to the same local food web, and several studies indicate that there is a general negative effect of fish on breeding ducks. This pattern has so far been addressed mainly within the framework of competition for common invertebrate prey, while predation by large fish as a force behind settlement and abundance patterns in ducks remains largely unknown. This is the first study to address the effect of fish predation on breeding ducks, isolated from that of competition, and the first experiment to explore the ability of ducks to identify and avoid lakes with high risk of fish predation. 2. We used a before-after control-impact design and 11 naturally fishless lakes. Waterfowl on the lakes were surveyed during the breeding season of 2005. Large adult pike (Esox lucius) were added to two lakes in early spring 2008, and waterfowl surveys were repeated on all 11 lakes. 3. Pike introduction did not affect the number of pairs on lakes during the nesting season in any of three focal duck species (mallard Anas platyrhynchos, teal Anas crecca, and goldeneye Bucephala clangula). During the brood-rearing season, however, there was a decrease in duck days in teal and goldeneye in lakes with pike, with similar trends observed in mallard. The number of goldeneye ducklings was also significantly lower in lakes with pike. We were unable to determine whether the response was attributable to direct pike predation or to broods leaving experimental lakes, but in either case, our study demonstrates high fitness costs for ducks breeding on lakes with pike. 4. The apparent inability of nesting ducks to detect pike and the clear fitness implications may influence the annual recruitment of ducks on a larger scale as pike are both common and widespread. Vegetation complexity and food abundance are likely to be of overriding importance when breeding ducks are choosing a nesting site. As pike have a strong influence on breeding birds, relying on vegetation and cues of food abundance, while ignoring indicators of predation risk from fish, could lead to lakes with pike acting as an ecological trap.

  • Presence of fish affects lake use and breeding success in ducks
  • 2010
  • record:In_t: Hydrobiologia. - : Springer. - 0018-8158 .- 1573-5117. ; 641:1, s. 215-223
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Several previous studies indicate that presence of fish has negative effects on waterbirds breeding on lakes, owing either to competition for common invertebrate prey or fish predation on ducklings/chicks. However, others have reported results to the contrary and it remains unresolved what factors trigger, inhibit, and modulate fish-waterbird interactions. The present study was designed to test the effect of fish presence per se, with a minimum of variation in possibly confounding environmental variables. Thus, after stratifying for area, depth, altitude, pH, and total phosphorus we compared 13 lakes with and 12 without fish (mainly pike Esox lucius and perch Perca fluviatilis) with respect to (i) general species richness of waterbirds, (ii) species-specific utilization and breeding success of two dabbling ducks (mallard Anas platyrhynchos and teal Anas crecca) and a diving duck (goldeneye Bucephala clangula). General species richness of waterbirds was higher on fishless lakes. Overall use (bird days) and brood number of teal and goldeneye were higher on fishless lakes. The latter also had more benthic and free-swimming prey invertebrates compared to lakes with fish. Mallard use, mallard brood number, and abundance of emerging insects did not differ between lake groups. Generalized linear models including fish presence as factor and considering seven environmental variables as covariates, confirmed that all waterbird variables except mallard days and broods were negatively correlated to fish presence. There was also a residual positive relationship of lake area on general species richness, teal days, and teal broods. Our data demonstrate a stronger effect of fish presence on diving ducks and small surface feeding ducks than on large surface-feeding ducks. We argue that observed patterns were caused by fish predation on ducks rather than by fish-duck competition for common prey.

  • Adaptive capacity in the multi-level management system of migratory waterbirds : a case study of participatory goose management in Sweden
  • 2022
  • record:In_t: Journal of Environmental Planning and Management. - : Routledge. - 0964-0568 .- 1360-0559.
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Adaptive management (AM) is one approach to manage migratory waterbirds, but obstacles to the implementation of AM require adaptive capacities in the management system (rules, institutions, action situations). This study aims to examine the adaptive capacity of participatory goose management in Sweden. Considering the biophysical and institutional context, we analyzed how tangible, individual, and governance assets were associated with technical and social learning. Interviews with informants in the national council for geese, swans, and cranes, and local management groups (LMGs) were conducted, and documentation reviewed. Results revealed evidence of a local preparedness in areas with an LMG. Nevertheless, the study highlighted a need to formalize the evolving system, to consider a more systematic implementation of AM (including regulations allowing for adaptive responses), and to ensure stakeholder acceptance for management tools and visions. The study illustrates the need for a broad set of assets to ensure learning in participatory management.

  • Are birdwatchers willing to participate in local goose management? : A case study from Sweden
  • 2023
  • record:In_t: European Journal of Wildlife Research. - : Springer. - 1612-4642 .- 1439-0574. ; 69:2
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Stakeholder involvement in wildlife management is important and requires knowledge about factors motivating such participation. With several goose populations increasing in Europe and goose management incorporating multiple objectives, involvement of stakeholder groups with diverse interests is needed. In this study, we examined how evaluations of geese (attitude and acceptance capacity), but also experiences of birdwatching and birdwatcher identity, were associated with willingness to participate in local goose management. A survey among members of Sweden's largest birdwatching organization was conducted (n = 5010). The majority of respondents, 64%, displayed a divided evaluation of geese, most frequently in terms of an overall positive attitude towards geese but a low acceptance for current goose population levels (i.e. acceptance capacity). Birdwatchers' willingness to participate in goose management was generally low. Whereas they were more willing to take part in goose counts (i.e. monitoring) than to participate in local goose management groups, they were least willing to contribute to mitigating crop damage through scaring geese. Results further revealed that birdwatchers with a divided evaluation of geese and an entirely positive evaluation displayed the highest willingness to participate in goose management. However, a stronger distinct birdwatcher identity as a result of more birdwatching experiences was even more strongly associated with higher willingness to take part in goose management. The results highlight a need to intensify efforts to engage stakeholder groups with an interest in conservation issues in the participatory goose management system in Europe.
