Quarter: 
April - June
Protocol Activities: 

Vegetation:

Planning calendar and field activities for 2011; Updating, correction and analysis of the database to participate in a workshop that will be promoted by RAINFOR.

 

Climate:

Climate Protocol developed the following activities: collection of climatic variables (precipitation, air temperature, relative humidity, solar radiation, diffuse radiation, photosynthetic active radiation - PAR and soil moisture), maintenance of sensors, data tabulation, sending data to the TEAM database; data analysis and discussion with Vegetation and Litterfall protocols, development of monthly and annual climatologic  bulletins with our results.

 

Terrestrial Vertebrates:

During this period focus on familiarization with the data analysis. In parallel, we made a planning application of the Protocol of terrestrial vertebrates in the Adolpho Ducke Reserve (north of Manaus). During this period the proposed new points were established in the field. We believe that these data will complement the knowledge of community dynamics of these organisms in the fragmentation and represent a significant increase in the number of collection points in the Central Amazon, achieving thus a number of 90 collection points, which is taken as ideal for the complication of the protocol. We also performed the selection of a temporary graduate scholarship to assist in the installation and logistical preparation of the excursions.

 

Protocol Problems: 

Vegetation:

- computer used to data analysis presented problems since last year and due to delay in contract renewal was not possible to get a new one;

- It was not reported the model of the compass we need to buy for use in mapping new individuals that will be recruited during the census;

- We don't receive the EcoPDA and the census will start in August. We need this equipment and training to use it.

 

Climate:

 - Problems occurred in the sensors that measure radiation Par, diffuse and global. We did the cleaning of sensors and other equipment, however the problem was not resolved. It is a defect in the equipment itself, and this needs to be replaced.

 

Logistical Problems: 

Terrestrial Vertebrates:

 

- One problem we face is to send supplies to the field to move to another camp. Often the driver has to go to the camp on weekends, outside work hours. I suggest that after the activity held in each "array" the team is transported to the city and return early next week for the field. This does not harm the sample and does not represent increased costs to implement the protocol.

Suggestions: 

Climate:

We are worried with the delay of the new equipment importation. The actual station is already showing defects, and we need to implement the new climate protocol

Another important point is with respect to variable wind direction and wind speed that is currently impaired by the vegetation around the station. This interference is already observed in the current protocol, because the automatic station - CR23X is installed in an area which is surrounded by vegetation with heights ranging from 10 to 35 m. Because of this natural barrier, the records of these two variables are affected. As a suggestion it would be interesting these two sensors be installed above the canopy allowing the registration of these variables more adequately, resulting also in a flexible time-series comparison with other experimental sites throughout the Amazon.
