The two constructs of interest were (a) students' attitudes toward women in science and society and (b) students' assessment of the classroom climate for women. The data included 398 matched pretest and posttest survey responses from a control group, a minimal enrichment group, and an increased enrichment group. Findings indicated that, although small course revisions did not influence students' attitudes toward women in science and society, such revisions had a positive influence on students' assessments of the classroom climate.}, number={1}, journal={PSYCHOLOGY OF WOMEN QUARTERLY}, author={Wyer, Mary and Murphy-Medley, Deena and Damschen, Ellen I. and Rosenfeld, Kristen M. and Wentworth, Thomas R.}, year={2007}, month={Mar}, pages={96–102} } @article{hess_bartel_leidner_rosenfeld_rubino_snider_ricketts_2006, title={Effectiveness of biodiversity indicators varies with extent, grain, and region}, volume={132}, ISSN={["1873-2917"]}, DOI={10.1016/j.biocon.2006.04.037}, abstractNote={Abstract The use of indicator taxa for conservation planning is common, despite inconsistent evidence regarding their effectiveness. These inconsistencies may be the result of differences among species and taxonomic groups studied, geographic location, or scale of analysis. The scale of analysis can be defined by grain and extent, which are often confounded. Grain is the size of each observational unit and extent is the size of the entire study area. Using species occurrence records compiled by NatureServe from survey data, range maps, and expert opinion, we examined correlations in species richness between each of seven taxa (amphibians, birds, butterflies, freshwater fish, mammals, freshwater mussels, and reptiles) and total richness of the remaining six taxa at varying grains and extents in two regions of the US (Mid-Atlantic and Pacific Northwest). We examined four different spatial units of interest: hexagon (∼649 km 2 ), subecoregion (3800–34,000 km 2 ), ecoregion (8300–79,000 km 2 ), and geographic region (315,000–426,000 km 2 ). We analyzed the correlations with varying extent of analysis (grain held constant at the hexagon) and varying grain (extent held constant at the region). The strength of correlation among taxa was context dependent, varying widely with grain, extent, region, and taxon. This suggests that (1) taxon, grain, extent, and study location explain, in part, inconsistent results of previous studies; (2) planning based on indicator relationships developed at other grains or extents should be undertaken cautiously; and (3) planning based on indicator relationships developed in other geographic locations is risky, even if planning occurs at an equivalent grain and extent.}, number={4}, journal={BIOLOGICAL CONSERVATION}, publisher={Elsevier BV}, author={Hess, George R. and Bartel, Rebecca A. and Leidner, Allison K. and Rosenfeld, Kristen M. and Rubino, Matthew J. and Snider, Sunny B. and Ricketts, Taylor H.}, year={2006}, month={Oct}, pages={448–457} } @article{firon_shaked_peet_pharr_zamski_rosenfeld_althan_pressman_2006, title={Pollen grains of heat tolerant tomato cultivars retain higher carbohydrate concentration under heat stress conditions}, volume={109}, ISSN={["0304-4238"]}, DOI={10.1016/j.scienta.2006.03.007}, abstractNote={Exposure to high temperatures (heat stress) causes reduced yield in tomatoes (Lycopersicon esculentum), mainly by affecting male gametophyte development. Two experiments were conducted where several tomato cultivars were grown under heat stress, in growth chambers (day/night temperatures of 31/25 °C) or in greenhouses (day/night temperatures of 32/26 °C), or under control (day/night temperatures of 28/22 °C) conditions. In heat-sensitive cultivars, heat stress caused a reduction in the number of pollen grains, impaired their viability and germinability, caused reduced fruit set and markedly reduced the numbers of seeds per fruit. In the heat-tolerant cultivars, however, the number and quality of pollen grains, the number of fruits and the number of seeds per fruit were less affected by high temperatures. In all the heat-sensitive cultivars, the heat-stress conditions caused a marked reduction in starch concentration in the developing pollen grains at 3 days before anthesis, and a parallel decrease in the total soluble sugar concentration in the mature pollen, whereas in the four heat-tolerant cultivars tested, starch accumulation at 3 days before anthesis and soluble sugar concentration at anthesis were not affected by heat stress. These results indicate that the carbohydrate content of developing and mature tomato pollen grains may be an important factor in determining pollen quality, and suggest that heat-tolerant cultivars have a mechanism for maintaining the appropriate carbohydrate content under heat stress.}, number={3}, journal={SCIENTIA HORTICULTURAE}, author={Firon, N. and Shaked, R. and Peet, M.

This review is the result of an interdisciplinary fusion of science and women's studies to critically assess teaching tools in undergraduate ecology education. We examine: (1) the representation of women and the coverage of social and cultural context in introductory ecology textbooks, and (2) student learning about women's contributions to ecology. Discipline demographics reveal that women are presented in textbooks less often than expected, and that explicit discussions of the social and cultural context of science are rare. When course content is enriched with material about women's contributions, student's awareness of women scientists improves. Such knowledge can play a critical role in proactively challenging students' perceptions of ecology and ecologists, creating a more positive classroom climate for all students, and introducing novel avenues of questioning and discovery.}, number={4}, journal={FRONTIERS IN ECOLOGY AND THE ENVIRONMENT}, author={Damschen, EI and Rosenfeld, KM and Wyer, M and Murphy-Medley, D and Wentworth, TR and Haddad, NM}, year={2005}, month={May}, pages={212–219} }
