Dispersal is a central aspect of the ecology, evolution, and conservation of species. Predicting how species will respond to changing environmental conditions requires understanding factors that produce variation in dispersal. We explore one source of variation, differences between sexes within a spatial population network. Here, we compare the dispersal patterns of male and female Parnassius smintheus among 18 subpopulations over 8 years using the Virtual Migration Model. Estimated dispersal parameters differed between males and females, particularly with respect to movement through meadow and forest matrix habitat. The estimated dispersal distances of males through forest were much less than for females. Observations of female movement showed that, unlike males, females do not avoid forest nor does forest exert an edge effect. We explored whether further forest encroachment in this system would have different effects for males and females by fitting mean parameter estimates to the landscape configuration seen in 1993 and 2012. Despite differences in their dispersal due presumably to both habitat and physiological differences, males and females are predicted to respond in similar ways to reduced meadow area and increased forest isolation.

Social media writing groups are an emerging phenomenon in the academic world. Combining the discipline, mentorship, and peer support of face-to-face writing groups, with the convenience, global reach, and interdisciplinary networks of social media, they offer a way for scholars to apply new digital technologies to the old problem of developing, maintaining, and protecting an academic writing practice. Despite their growing popularity, however, there has been little critical or empirical analysis of these groups. Using Shut Up & Write Tuesdays (SUWT) as a case study, this chapter examines the purpose, use, outcomes, and challenges of a social media writing group for academics. Usage data from the three SUWT Twitter accounts, a survey of SUWT participants, and the narrative reflections of the SUWT hosts, are drawn together to highlight the value, strengths, and limitations of social media writing groups as a scholarly activity in the digital age.
