Dongjing Sun, visiting scientist.
Home institute: Experimental Center of Tropical Forestry, Chinese Academy of Forestry
I completed my BA and MSc in forestry and forest ecology at the Faculty of Forestry, Guangxi University, China, and have been working as a research scientist at the Experimental Center of Tropical Forestry, Chinese Academy of Forestry, in Pingxiang city, Guangxi Province, China since 2011. Generally, my interest is in multifunctional and effective forest management models for plantation system, estimating the ecological functions in different ecosystems, and understanding how environmental factors affect the productivity and ecological functions of the forest.

Esthevan Gasparoto, visiting graduate student.
Home university: University of São Paulo, São Paulo, Brazil
Esthevan was born and raised in São Paulo, Brazil. He obtained his forest engineering degree from the Federal University of Sao Carlos (UFSCar) in Brazil, and is currently an MSc student in Forest Management at University of São Paulo (ESALQ/USP). In 2014-2015 he participated of the Emerging Leader in the Americas Program (ELAP) as a visiting researcher at UBC under the supervision of Peter Marshall. His task involved the integration of orbital images and multivariable geostatistics approaches to estimate of wood volume in Eucalyptus spp. pulp forests. Esthevan’s special interests involve multivariable analysis, geostatistics, and new technologies for forest inventory.

My study focuses on abortive phenomenon of pecan, especially the off-year abortive phenomenon, in the process of development on two promoting varieties, Mahan and Pawnee. Through slice observation of light microscope on these two species, scanning electron microscopy (SEM) and transmission electron microscopy (SEM), the internal growth phases are divided into four discrete periods. Nonaborting and aborting pistillate flowers were compared in each period to find out aborting stages of development of pistillate flowers. At the same time, in the experiment of pecan phenology phase and annual growth, the accumulation of a large number of basic data is used to establish a model to predict pecan annual output. As a whole, my interest is to estimate the annual production of fine varieties after understanding and making clear the internal development process and external influencing factors, which, having a significant economic benefit, therefore may improve and stabilized the pecan yields.
