Climate change causes greenhouse gas emission by plants
|
Global warming seems to be self-sustaining by making plants emit the potent greenhouse gas, methane (CH4), while simultaneously reducing their assimilation of CO2. This conclusion was obtained by Mirwais M. Qaderi and David M. Reid from University of Calgary, Canada, who tested methane emission and several growth parameters from six crop species grown under various environmental conditions. An increase in temperature from 24/20 °C (day/night) to 30/26 °C led to a 15% increase in methane emission, while the effect of water stress, which will accompany global warming in many regions, increased emission of the greenhouse gas by 22%. The figures are average measurements from faba bean, sunflower, pea, canola, barley and wheat. Under ambient conditions the six crops emitted between 85 (barley) and 170 (pea) ng methane per g dry weight per hour. At the same time, the higher temperature caused CO2 assimilation to decrease 27%, while water stress reduced CO2 assimilation by 31%. The researchers will now investigate how elevated CO2 levels affect methane emission in order to get a better picture of how global warming can turn plants into greenhouse gas contributors.

NEW: Post open positions and meetings on the SPPS homepage
|
| |
|
|
You can access the new sections from the SPPS homepage under the 'Open Positions' and 'Meetings & Links' tabs. From www.spps.fi
|
|
|
Two exciting new features on the SPPS homepage allows the plant community to share information on open positions and forthcoming meetings. The new sections - Open Positions and Meetings & Links - list available research positions and forthcoming meetings in all fields of plant biology, respectively, so you can easily browse through them and find the information, that is right for you.
The new sections are not limited to those who are looking for a new job or a meeting to go to. You can also post your own open positions or meetings and share them with colleagues all over the world. These new features make it extremely easy to recruit the best candidates and to attract a crowd for your meeting or conference. Posting a new open position or meeting is a breeze and below you can see how you can do it in just a few, simple steps.
1.On the SPPS homepage, click the 'Open Positions' tab to enter the new section. The column to the left displays all the open positions, while the right column contains a form where you can enter details of the position you want to post. Lets have a closer look at the form....
2.The form contains the relevant fields for your open position. Start filling in the fields and make sure to type a correct email address in the Contact-field and a legal internet address in the More info-field. Under Description you can type up to 1000 characters.
3.When you have filled in all the details, click Post position. Don't worry about if everything is strictly correct. The system will automatically check if all fields are filled out and if the email address appears to be valid. Even if everything is OK, you will still have the option to correct the information or even cancel your posting.
4.Ups.... You forgot to fill in the Location-field!
5.Fill in the field and correct any other fields if necessary. Then press Post corrections - or cancel.
6.With no red warnings your open position is now ready to be submitted, and you see it exactly as it will appear on the SPPS homepage. If you are satisfied press Submit final position - or continue to make corrections in the form on the right.
7.Congratulations! Your open position has now been submitted to the SPPS secretary and upon approval it will be posted on the homepage. This step is needed only to assure that unserious spam-like entries will not appear among the real postings on the Open Positions section. Approval will only take a short time - from a few hours to a few days.

It is just as simple to post a new meeting. Try it now!
|
|
|
Now that you are familiar with how to post an open position, you will have no trouble posting a new meeting under the Meetings and Links section - it follows exactly the same simple procedure.
We hope that the members og SPPS, the readers of the SPPS Newsletter and all other with an interest in plant biology will embrace these two new features.
Check out the new Open Positions and Meetings & Links sections here.
