The neural basis of Drosophila larval light/ darkness preference

In a project funded by NSFC,a team led by Associate Professor Gong Zhefeng and Professor Liu Li from the Institute of Biophysics,Chinese Academy of Sciences,discovered that two pairs of central brain neurons control the switch of the preference between light and darkness,by applying the GAL4/UAS system to block function of certain neural cells and investigating the consequent changes in Drosophila larval light avoidance behavior.A short report article published on Science on Oct.22,2010 reported this discovery. According to the report,animal behaviors are generally quite flexible.Animals can adjust their behavior according to the changes in natural environment,nutritional condition as well as factors like age.But,

Exceptionally preserved brachiopods from the Chengjiang Lagerst（a｜¨）tte（Yunnan,China）：Perspectives on the Cambrian explosion of metazoans

The Cambrian explosion was coined to describe the geologically sudden appearance of numerous bilaterian body plans（Phyla）around the Ediacaran-Cambrian transition,around 565-520million years ago.Many explanations and conjectures have been postulated in order to explain the pattern and duration of this explosive radiation of many different phyla of early metazoans.Here,we focus on the evolution of a phylum of marine suspension-feeding animals—the brachiopods,as exemplified by the exceptionally preserved taxa from the celebrated Chengjiang Konservat Lagerst（a｜¨）tte（Yunnan,China）.The abundant soft-bodied preservation at these fossil quarries gives us the only firm insights into what brachiopods looked like and how they functioned and lived when they first appeared on the Earth.Studies of Chengjiang brachiopods demonstrate that the early animals developed a remarkably varied organization of tissues and organs shortly after the onset of Cambrian explosion.In the marine suspension-feeding brachiopods,most importantly the tentaculate feeding structure of early brachiopods is already differentiated into two shapes of lophophore,anteriorly coiled（spiralled）and posteriorly arching tentacle crowns and the unique latter type was previously not documented from fossil and living brachiopods.Also unlike any known Recent brachiopod,all the known Cambrian brachiopods from Chengjiang have an open digestive tract that was disposed either as a Ushaped gut in linguliform and stem group brachiopods,or straight gut with a posterior anus in some calcareous-shelled stocks.Moreover,in contrast toliving lingulids,all the Cambrian brachiopods have an epibenthic lifestyle either cemented by a ventral valve or attached by variable pedicles to establish complex ecological community encompassing primary tierers and variable secondary tierers.It is therefore assumed that brachiopods were the first benthic metazoan that achieved their success in ecological stratification and tiering complexity by late Atdabanian.The setae are also important for the brachiopod suspension-feeding life style,and in the Chengjiang braehiopods they include two types cilia-like and spine-like setae.The mantle canals of different braehiopod species are also distinctly variable in arrangement,mainly disposed in pinnate,baeulate and peripheral conditions.Of these,the peripheral disposition of mantle canals is for the first time proposed here so as to differentiate from the bifurcate condition in recent lingulids in that the former is devoid of posteriorly extending main trunks of sinus,but possesses a diverging dorsal vascula media in dichotomy.
