  • Please upload your file by the deadline, even for presentations that have not applied for a poster award. In addition, the deadline for uploading graphical abstracts is under consideration. If you do not upload the files by the core time, they may be treated as unpublished, so please prepare early.

Poster Award

  • The Ecological Society of Japan awards excellent poster presentations to encourage students. The important criteria in the selection are the information transmission ability of the poster and the quality of the research. If multiple posters achieve the same score in the review, the poster that can be better understood in English will be ranked higher.

Consideration for color vision diversity and comfortable online resources

About 0.2–0.5% of females and 5–10% of males have visual characteristics that make it difficult to distinguish differences in colors such as red and green (color blindness). In online presentations, it is often difficult for speakers to point out sentences or figures using a pointer, and they often use only verbal explanations relying on colors (e.g., “The red points in the figure show a larger change than the green ones”). Such presentations are difficult for colorblind people to understand. Therefore, careful considerations for color barrier-free presentations are requested in online presentations. To put it simply, it is better to use orange and blue than red and green, and to use a layout that does not rely excessively on color.

Watching a screen for a long time can be a great burden for the audience. To reduce the burden on the eyes, the contrast between the background and text color should be reduced. If the background is white, it is effective to use slightly lighter black (gray) text. You can also use a pale color background to reduce the contrast between the black text and the background color. Reducing the contrast between the text and the background is also a barrier-free method for people with visual sensitivity.
