Gamergates in the myrmicine genus <Emphasis Type="Italic">Metapone</Emphasis> (Hymenoptera:Formicidae)

Gamergates (i.e. mated reproductive workers) are mostly known from ant species within the Ponerinae. We report here the discovery of gamergates in two species of the subfamily Myrmicinae. Until now, mated reproductive females in colonies of myrmicine species have been considered morphologically distinct from the worker caste. However, in two species of the myrmicine Metapone (Metapone madagascarica and a newly discovered, not yet described Metapone species) all workers have six ovarioles and a spermatheca; and some of them are mated. There are no morphological differences between mated and non-mated workers. Field observations and laboratory studies indicate that colonies of the Metapone species can reproduce with gamergates only.     

Vocal acrobatics in a Chinese frog, <Emphasis Type="Italic">Amolops tormotus</Emphasis>

Although amphibians are highly vocal, they generally emit only a limited number of acoustic communication signals. We report here the extraordinarily rich vocal repertoire of Amolops tormotus, a ranid species in China. These frogs produce countless vocalizations, some of which share features of birdsong or primate calls, e.g., ultrasonic frequency components, multiple upward and downward FM sweeps, and sudden onset and offset of selective harmonic components within a call note. Frame-by-frame video analysis of the frog's calling behavior suggests the presence of two pairs of vocal sacs that may contribute to the remarkable call-note complexity in this species.

不同状态MnO2对废水中As(III)的吸附研究

利用MnO2对含As(III)废水进行了吸附实验, 结果表明, MnO2对As(III)有着较强的吸附能力, 其饱和吸附量为44.06mg/g(δ-MnO2)和17.9mg/g(ε-MnO2), 阴离子的存在使MnO2吸附量有所下降, 一些阳离子(如Ga3+、In3+)可增加其吸附量, 吸附后的MnO2经解吸后可重复使用.     

Inventory of emissions from major air pollutant categories in Turkey

In this study, an inventory of air pollutant emission estimates from major air polluting sources in Turkey for period between 1985 and 2005 with 5-year intervals were estimated. Inventory covers anthropogenic sources of five major air pollutants of particulate matter, sulfur dioxide, carbon monoxide, nitrogen oxides and non-methane volatile organic compounds. Their break-down with respect to main activity sectors were shown and their distribution by the largest industrial source categories were worked out as annual estimates. This inventory and its analysis point to serious environmental implications of air pollutants and a need to develop a policy plan for reducing these emissions.

分子生物学在渔业环境保护中的运用

分子生物学理论和技术在渔业环境保护与监测工作中的应用越来越得到人们的重视：生物体的多种酶已被用作监测水环境污染的指标；金属硫蛋白等生物体解毒体系在监测和防治水体重金属污染方面发挥显著作用；核酸是生物体遗传信息载体，以核酸质量变化监测水环境污染已取得较好的效果。据此就分子生物学在今后渔业环境保护中的运用提出了观点。
