A paper presentation is 20 minutes long or less and describes a research project and its findings, or a well-documented theoretical/practical perspective.To register a paper presentation, please send us an abstract with your name, institutional affiliation, presentation title, 150-word description, and up to five (5) keywords. Also, please identify the conference theme(s) (see above) and send this material: RCIS@ryerson.ca; Deadline extended until Dec. 14, 2012.
Special panels are 90 minutes long and typically consist of 3-4 presentations (or 3 papers and a discussant). If you wish to propose and organize a panel, please collect all information (i.e. panel title, names of presenters, presentation titles, presentation abstracts of up to 150 words each, and keywords) and send it as a package to: RCIS@ryerson.ca; Deadline extended until Dec. 14, 2012.

Roundtables are 90 minutes long and are less structured than paper panels. A roundtable can contain 3-6 discussants exchanging ideas and/or demonstrating methods of practical relevance. If you wish to propose and organize a roundtable, please collect all information (i.e. roundtable title, names of presenters, a 150 word abstract describing the theme of the roundtable, and keywords) and send it as a package to: RCIS@ryerson.ca; Deadline extended until Dec. 14, 2012.
An online conference evaluation form is available at www.aacu.org/meetings/diversityandlearning/DL2012/evaluation.cfm. Your feedback is important to us and we hope that you will take a few minutes to tell us about your conference experience and recommendations for future Network events.
The main chemical components of S. invicta venom are 2-methyl-6-alkyl or alkenylpiperidines (Chen et al. 2009). However, other pyridine alkaloids were also isolated and identified, including, 2-methyl-6-undecylpyridine, 2-methyl-6-tridecenylpyridine-isomer, 2-methyl-6-tridecenylpyridine-isomer, 2-methyl-6-tridecylpyridine, 2-methyl-6-pentadecenylpyridine-isomer, and 2-methyl-6-pentadecylpyridine (Chen et al. 2019a). Liu et al. (2017) suggested that by using the whole body solvent-soaking method, an adequate amount of fire ant venom alkaloids can be extracted for chemical analyses and bioassays. Fox et al. (2018) also developed a straightforward method for extracting within minutes aculeate S. invicta venoms by centrifugation. The venom alkaloids of S. invicta have many functions. For example, an alkaloid isosolenopsin A from S. invicta queens could knockdown its competitors rapidly and plays a role in successful nest founding (Fox et al. 2019). Venom alkaloids can also inhibit germination and hyphal growth of entomopathogenic fungi (Obin and Vander Meer 1985). Research has shown that venom alkaloids inhibited the plant pathogen Pythium ultimum and bacterial canker of tomato, and thus there is the possibility for developing venom alkaloids as novel fungicides and bactericides (Li et al. 2012, 2013). Cuticular hydrocarbons (CHCs) are a type of chemicals that prevent desiccation, aside from playing a role in signal communication (Hu et al. 2017). Xu et al. (2018a) found that CHCs of S. invicta can retain more water under relatively higher temperature, which helps S. invicta in occupying warmer environment, and they concluded that CHCs played an important role in shaping the distribution of fire ants in the USA. 2ff7e9595c
