Abstract: Recent work on the ecosystem service of bio ersity suggests that higher pollinator ersity could lower pollen limitation, but these two aspects of plant–pollinator communities have only rarely been causally connected. Here we present a review of studies that produced quantitative assessments of both pollinator ersity and evenness as well as pollen limitation of focal plant species. Although pollen limitation is expected to be lower when pollinator ersity is high, our analysis suggests this relationship is weak. The relationship may be obscured when features of the plant species (e.g., average level of specialization) are confounded with features of the plant communities (e.g., habitat). We encourage researchers investigating pollen limitation to consider including measures of ersity of the floral visitors, and their effectiveness. These data would permit a more powerful test of the relationships among these variables and improve our understanding of the critical elements of stable plant–pollinator networks.

Abstract: To compare patient reported outcomes between robotic assisted surgery and non-robotic assisted surgery. This was an international web-based survey based on a qualitative research and literature review, an internet-based questionnaire was developed with approximately 70 items. The questionnaire included both closed and open-ended questions. Responses were received from 193 men of whom 86 had received either open (OP) or robotic (RALP) surgery. A statistically significant (p=0.027), ranked analysis of covariance was found demonstrating higher recent distress in the robotic (RALP) surgery group. Although not statistically significant, there was a pattern of men having robotic (RALP) surgery reporting fewer urinary and bowel problems, but having a greater rate of sexual dysfunction. Men who opt for robotic surgery may have higher expectations for robotic (RALP) surgery, when these expectations are not fully met they may be less likely to accept the consequences of this major cancer surgery. Information regarding surgical choice needs to be tailored to ensure that men diagnosed with prostate cancer are fully informed of not only short term surgical and physical outcomes such as erectile dysfunction and incontinence, but also of potential issues with regards to masculinity, lifestyle and sexual health.

Abstract: Within the Apiaceae, subtle variation in reproductive characters such as dichogamy, pollinator specificity and umbel density may cause cryptic specialisation and be responsible for the ersity of life histories and gender expression in the family. To address the paucity of information for Australian species we investigated the reproductive ecology of the native perennial herb, Trachymene incisa Rudge subsp. incisa. T. incisa exhibits protandry within flowers and umbels however, an overlap of 3 days in male and female phases among umbels of consecutive orders permits geitonogamous pollination. There are 72 ± 2.0 (n = 74) white flowers per umbel and nectar is presented during the male and female phases. Apis mellifera appears to be the main diurnal pollinator. The pollen : ovule ratio is 1902 : 1, indicating that T. incisa is a facultatively xenogamous species. The long phase of pollen presentation and the low natural seed set of about 45% implies that many flowers are functioning as pollen donors only. Controlled pollination experiments showed that self-pollen led to lower seed set than cross, open and supplemental applications. Early and late-produced cohorts differed in days to emergence but not in seed mass or final percentage emergence.

Abstract: To explore issues related to sexual function and relationships, for men and their wives or partners, following diagnosis and treatment for prostate cancer. A diagnosis of prostate cancer and subsequent treatment result in a significant number of men experiencing some impairment to their sexual function. There is scant research into the impact of changed sexual function on these men's masculinity, sexuality, intimate relationships and their needs regarding counselling and supportive care. Internet-based survey. Focus groups and couple interviews were used to improve validity for questionnaire items designed to provide insight into men's experiences of prostate cancer in areas such as sexual function and relationships. The questionnaire included both closed and open-ended questions and had the option for the wife or partner to complete a section. Qualitative research revealed 17 specific categories within three key themes: sexual dysfunction, loss of libido and masculinity. The questionnaire found, unexpectedly, the majority of men said that they had sufficient emotional and psychological support. Wives artners confirmed cancer had impacted on their partner's feelings of masculinity (71%), compared to 42% of men who felt that this was the case. Predictors of loss of libido, erectile dysfunction and 'feeling less of a man' were developed. Univariate predictors included hormone therapy, regrets about treatment choice, cancer having impacted on masculinity and distress during the last week. Men are not able to clearly identify the challenges prostate cancer brings especially changes to their masculinity. The findings strongly suggest that for men with prostate cancer, nursing assessments of men's sexual health be augmented by information gained from their partners further, these assessments should be augmented with a careful exploration of these men's psyche guided by the knowledge that masculinity influences perceptions of self (being a man) and help seeking.
