Playing with persona:Highlighting older adults’ lived experience with the digital media

During the COVID-19 pandemic lockdowns (2020-2021), almost all facets of life were rendered digital – health, work, schooling, and logistics. In this phenomenon, not only did digital access become synonymous with social inclusion but inequalities were also amplified – particularly in the case of older adults (65 years and over). Contemporary older adults represent one of the most diverse spectrums of digital media users – spanning from technologically savvy to non-users. As the first generation of older adults to age in and through data in a data-saturated world, their understandings and experiences can teach us much about the possibilities and limitations of new media. Understanding these practices through cultural probes – like drawing, photos and writing prompts – can enable playful behaviours that not only elicit new thoughts and actions but also allow insight into some of the tacit lived experience that can support opportunities for technological use. In this paper, we ask: How can we playfully co-design through personas to enhance understandings of older adults’ lived experience of digital media? In this paper, we focus on the six co-design workshops in which we deployed personas as representations of digital experience to challenge, explore, provoke and help build nuanced tools for implementation. Through personas, speculative fiction and lived experience collide, offering some fascinating ways to rethink the digital-social dimension for older adults now and into the future

Climatic and Biogeochemical Effects of a Galactic Gamma-Ray Burst

It is likely that one or more gamma-ray bursts within our galaxy have strongly irradiated the Earth in the last Gy. This produces significant atmospheric ionization and dissociation, resulting in ozone depletion and DNA-damaging ultraviolet solar flux reaching the surface for up to a decade. Here we show the first detailed computation of two other significant effects. Visible opacity of NO2 is sufficient to reduce solar energy at the surface up to a few percent, with the greatest effect at the poles, which may be sufficient to initiate glaciation. Rainout of dilute nitric acid is could have been important for a burst nearer than our conservative nearest burst. These results support the hypothesis that the characteristics of the late Ordovician mass extinction are consistent with GRB initiation.Comment: 12 pages, 2 figures, in press at Geophysical Research Letters.

The past and future roles of competition and habitat in the range-wide occupancy dynamics of Northern Spotted Owls

Slow ecological processes challenge conservation. Short-term variability can obscure the importance of slower processes that may ultimately determine the state of a system. Furthermore, management actions with slow responses can be hard to justify. One response to slow processes is to explicitly concentrate analysis on state dynamics. Here, we focus on identifying drivers of Northern Spotted Owl (Strix occidentalis caurina) territorial occupancy dynamics across 11 study areas spanning their geographic range and forecasting response to potential management actions. Competition with Barred Owls (Strix varia) has increased Spotted Owl territory extinction probabilities across all study areas and driven recent declines in Spotted Owl populations. Without management intervention, the Northern Spotted Owl subspecies will be extirpated from parts of its current range within decades. In the short term, Barred Owl removal can be effective. Over longer time spans, however, maintaining or improving habitat conditions can help promote the persistence of northern spotted owl populations. In most study areas, habitat effects on expected Northern Spotted Owl territorial occupancy are actually greater than the effects of competition from Barred Owls. This study suggests how intensive management actions (removal of a competitor) with rapid results can complement a slower management action (i.e., promoting forest succession)

The role of incentive-based instruments and social equity in conservation conflict interventions

Conflicts between biodiversity conservation and other human activities are multifaceted. Understanding farmer preferences for various conflict mitigation strategies is therefore critical. We developed a novel interactive game around farmer land management decisions across 18 villages in Gabon to examine responses to three elephant conflict mitigation options: use of elephant deterrent methods, flat-rate subsidy, and agglomeration payments rewarding coordinated action for setting land aside for elephants. We found that all three policies significantly reduced participants’ inclinations to engage in lethal control. Use of deterrents and agglomeration payments were also more likely to reduce decisions to kill elephants in situations where levels of social equity were higher. Only the two monetary incentives increased farmers’ predisposition to provide habitats for elephants, suggesting that incentive-based instruments were conducive to pro-conservation behavior; different subsidy levels did not affect responses. Likewise, neither participants’ socioeconomic characteristics nor their real-life experiences of crop damage by elephants affected game decisions. Killing behavior in the games was 64% lower in villages influenced by protected areas than in villages surrounded by logging concessions, highlighting the need to address conservation conflicts beyond protected areas. Our study shows the importance of addressing underlying social conflicts, specifically equity attitudes, prior to, or alongside addressing material losses

Climate emergency summit III:nature-based solutions report

An RSGS & SNH report from the Climate Summit held in April 2020"The Climate Emergency is the result of burning fossils fuels and changes in the way we use the land that short-circuit global carbon and nitrogen cycles. To remain within safe climate limits (1.5-2°C), the remaining carbon budget for all people, and for all time, is now so small that stopping fossil fuel use, while essential, will not by itself address the problem. Changing the way we use the land and sea is now essential. Nature-based solutions are vital to creating a safe operating space for humanity.

Range-wide sources of variation in reproductive rates of northern spotted owls

We conducted a range-wide investigation of the dynamics of site-level reproductive rate of northern spotted owls using survey data from 11 study areas across the subspecies geographic range collected during 1993–2018. Our analytical approach accounted for imperfect detection of owl pairs and misclassification of successful reproduction (i.e., at least one young fledged) and contributed further insights into northern spotted owl population ecology and dynamics. Both nondetection and state misclassification were important, especially because factors affecting these sources of error also affected focal ecological parameters. Annual probabilities of site occupancy were greatest at sites with successful reproduction in the previous year and lowest for sites not occupied by a pair in the previous year. Site-specific occupancy transition probabilities declined over time and were negatively affected by barred owl presence. Overall, the site-specific probability of successful reproduction showed substantial year-to-year fluctuations and was similar for occupied sites that did or did not experience successful reproduction the previous year. Site-specific probabilities for successful reproduction were very small for sites that were unoccupied the previous year. Barred owl presence negatively affected the probability of successful reproduction by northern spotted owls in Washington and California, as predicted, but the effect in Oregon was mixed. The proportions of sites occupied by northern spotted owl pairs showed steep, near-monotonic declines over the study period, with all study areas showing the lowest observed levels of occupancy to date. If trends continue it is likely that northern spotted owls will become extirpated throughout large portions of their range in the coming decades
