| 200 word (maximum) main text. | Body size is a central feature of any organism, reflecting its physiology, ecology and evolutionary history. Marine microplankton are major contributors to the particulate inorganic carbonate (foraminifers and coccolithophorids) and opal flux (radiolaria and diatoms) in the ocean and, hence, size changes in these organisms can influence global biogeochemical cycles. This paper discusses abiotic influences on micro- and macroecological size changes among major marine plankton groups, linking these to evolutionary size changes during the Neogene. We review the patterns and outline the causes of size changes geographically and through time in coccolithophorids, foraminifers and radiolarians.
The main feature of the Neogene size record is a dramatic size increase in foraminifers, a similarly dramatic reduction in the size range of coccolithophorids and highly variable size patterns in radiolarians. We argue that the observed pattern is too complex to be explained by a simple common forcing and propose that speculations on the response of oceanic biomineralisation to global warming have to consider the scales at which marine plankton evolve. |
| Optional extra content | Abstracts can optionally also include:
references, images, extra text. I.e they can be extended abstracts, but they must include a basic abstract. Any extra content will appear after the main text. Including an image or two is especially welcome. These can only be submitted in jpeg or png format and must be <500kb in size. |
Abstract submission
Pleas submit abstracts as an email message or attachment. Send to: tmsconf2020@gmail.com.
Acceptable formats - plain text, MS Word file (.docx), .rtf, and for images .jpeg or .png. Deadline 15th October 2020.
Abstract selection
Virtual conferences have the added advantage that they widen participation for those who might not otherwise be able to participate. We strongly encourage early career researchers and those from historically underrepresented groups in STEM to attend and present. If abstract selection is necessary (in the case that there are more abstracts received than talk slots available), we will prioritise students and other early career researchers, and abstracts will be anonymised before selection to avoid unconscious bias.
Posters
Abstract submission
Abstracts for posters should be submitted in the same format as for talks tmsconf2020@gmail.com and by the same deadline, 15th October. Maximum of two posters per first author. Posters can be on any micropalaeontology-related topic, but should document recent original work by the authors. There is no limit on the total number of posters we can show and we will not vet posters for scientific excellence.
Poster preparation
- Posters should be prepared as for a printed poster (portrait or landscape format) then saved as a PDF file for upload (NB This is the default format if you wish to try something different feel free to contact us).
- Colour can be used freely.
- PDFs are highly scaleable so there is a lot of flexibility in how you size them, i.e. there is no need for precise instructions.
- Basically produce the poster so it looks right on your computer then save it as a PDF.
- As an example the posters here were produced originally in Powerpoint for A0 physical printing then saved as A4 pdf documents from inside Powerpoint.
- A good poster should look (1) interesting at a fairly small scale (2) be easily read on a laptop screen.
- You can expect readers to pan and zoom around the page, but text should be legible at a scale where you can fit about a quarter of the poster on screen.
- Posters will not be edited and the content is entirely the responsibility of the authors.
- Posters may be rejected if they are are not relevant to the conference (i.e. if they don't deal in some way with micropalaeontology or the biology of microfossil producing groups), or if they include plagiarised material, offensive content, etc.
- Avoid using copyright images or obtain permission in advance (NB Images can be copied from mikrotax and nannotax without specific permission but please acknowledge the source).
- If you wish to limit use of your poster include a copyright notice on it, and consider applying access control to the PDF file - you can do this in AcrobatPro, or similar software, or you can ask us to do it for you.
- File size - the smaller the file size the easier it will be for people to view your poster. Maximum file size is 10Mb and we strongly recommend having much smaller files - ideally <2Mb.
- The main cause of large file size is large images - e.g. a single camera image may be 10Mb in size where you only need it to be 200kb. Photoshop and similar programs allow you to resize images before including them on a poster. AcrobatPro and similar programs allow you to save PDFs with the images compressed.
- If you have a poster with a large file size a straightforward solution is to extract the component files from a copy of the file, find the large files, reduce their size, then replace them in the original file. With Powerpoint presentations, you can change the file extension to .zip, then unzip the package and find the images in the contents. This is explained here, on Macs you need to (1) change the file extension to .zip, (2) extract the files using StuffIt expander or similar. Alternatively for Macs FileJuicer does the file extraction perfectly.
Poster submission
Please submit posters as an email attachment. Send to: tmsconf2020@gmail.com. Deadline 1st November, but earlier submissions are welcome, and you do not need to wait for "approval" of abstracts.
Acceptable formats - pdf, ppxt, jpeg, png. We recommend sending as pdf files but if you are not able to generate pdf files we can do the conversion of pptx files. Alternatively, if you prefer to minimise use of your files, you can send them as an image file. Posters will be scanned for viruses and if any are detected we will request new clean copies.
