This article examines the use of photo-elicitation interviews as a qualitative research method when studying aspects of adolescent behaviour. In particular, it describes and evaluates the use of photo-elicitation interviews to investigate the outdoor education experiences of a group of 34 (12 male, 22 female) New Zealand secondary school students (aged 14-15 years old) who attended a school-based outdoor education programme, referred to throughout as 'school camp'. Results indicate that the use of cameras, and hence photographs, are attractive features of the technique that render it suitable for engaging young people in academic research and exploring social experiences. While the inclusion of cameras also presents some methodological limitations and ethical considerations, photo-elicitation interviewing is a useful addition to the suite of qualitative research methods employed in outdoor education research.

1. An increasing number of studies have shown that senescence, the functional decline in traits and increased risk of mortality with increasing age, occurs in organisms in wild populations, but there is a wide range of diversity in the patterns of senescence across species.2. The antagonistic pleiotropy and the disposable soma theories of senescence predict that there will be life-history trade-offs between performance at early-and late-life stages. Plants show variation in senescence patterns and thus provide an opportunity to evaluate life-history trade-offs and senescence. Many plant species can be easily followed demographically and their environments, resources and allocation to reproduction can be manipulated, which makes them particularly good models to address these questions. 3. We compared the results from 22 studies of plant senescence in the wild and compiled 20 examples of life-history trade-offs in plants. Some of the unique features of plants that may influence senescence patterns and trade-offs in the wild are highlighted through the results.4. We found all three age-specific patterns: age decline, age improvement and no change with age for plants in the wild. Most species showed an age-dependent decline in at least one trait but, even within a species, the age-specific patterns of traits varied. Results also showed that trade-offs vary across environments and that plants can manipulate their resource pool through increases in photosynthesis, which will influence the manifestation of trade-offs.5. We conclude that aspects of plant biology including dynamic resource pools, the impact of size, dormancy and below-ground storage may influence both the patterns of senescence and life-history trade-offs. The diversity of plant life forms and life cycles provide a wealth of opportunities to experimentally study senescence in the context of life-history trade-offs.

This paper reports on a New Zealand study that obtained firsthand narrative accounts from a group of Year 10 (14 to 15 years old) secondary school students who were provided with 27-exposure disposable cameras on which they were asked to take a series of photographs to record what a residential school camp was like for them. Follow-up individual photoelicitation interviews with the 32 self-selected respondents (21 female, 11 male) revealed that school camp is an enjoyable, socially different experience where students are able to spend time with their friends and develop their peer networks in a temporary community. Researchers are encouraged to use photo-elicitation interviews when their research objectives traverse the changing preoccupations of adolescents or of other groups during their life courses, and practitioners should consider developing programmes that incorporate the social youth development outcomes salient to adolescent participants.
