The IMSP Research Colloquium provides a venue for the presentation of researches done by faculty members of IMSP or by invited speakers. It serves as a forum for scholarly debate and discussion of research problems of a collaborative nature.
29th Research Colloquium (March 15, 2013)
"Physics in honeybee embryonic development under thermal stress*"
by Prof. Lou Serafin M. Lozada
Embryonic development in an organism follows several stages of cellular division, migration, and segregation dictated by several factors. These could be governed by proteins, morphogenes and other biological elements that are affected by physical parameters like temperature, viscosity of the cellular system, and cell size. In this study, we determined the effect extreme temperatures on embryonic development. In this talk, I will present how temperature affects the development of honey bee Apis mellifera embryo. We examine the number of cells and cellular movement along the anterior-posterior axis during the embryonic development at -7oC, 35oC and 42oC. Results show that the number of cells and the rate of cell division are highest at the anterior for three temperatures during the first 8 hours of development. However, values are low in embryos kept at -7oC while highest at 42oC. At later time, only the samples kept at 35oC continue to develop. For future works, our group would like to study cellular communication during development and ventilation in beehives.
*This lecture is based on the undergraduate thesis of Ms. Ma. Angelique T. Mangubat (BS Applied Physics), which was successfully defended in March 2012. This work was conducted in collaboration with Dr. CR Cervancia and Mr. A Fajardo of the UPLB Bee Program. Lou was Ms. Mangubat's thesis adviser.
"On Mathematics of Neurosociology"
by Prof. Jomar F. Rabajante
I will share some ideas on how to apply mathematics in the study of brain structure and function. I will discuss some aspects of Theoretical Neuroscience and some thoughts about relationship of Neurobiology and Sociology. This talk will focus on the factors affecting the collective behavior of eusocial species.
I will also take this an opportunity to impart to the audience the various research activities that the Computational Bee Ecology group of the UPLB Bee program is doing.
