Diurnal colour change in a sexually dimorphic trait in the Andean lizard Anolis heterodermus (Squamata: Dactyloidae)

Sexual dimorphism in body size, shape and colour is widespread in lizards as well as in other taxa. In the context of sexual selection, these sex differences are commonly manifested as exaggerated male traits, which are selected by females to assess the quality of males. However, differences in sex by environment interactions can also lead to sexual dimorphism. The genus of Anolis lizards is particularly well known for sharp sexual dimorphism in dewlap colour and size; however, this is not the case in all anole species. Using digital image analyses, I assessed the existence of sexual differences in the diurnal change in colour and size of a conspicuous patch on the tail of the lizard Anolis heterodermus Duméril 1851. Results showed that the tail patch of both males and females changed in colour, but not size, from red to blue throughout the day in a similar fashion. This process took almost half a day to complete and occurred in the absence of conspecifics, suggesting that the change itself may not have an active role in social communication. However, the colour patches of males were consistently larger. The cause of the substantial variation in colour and size of the tail patch of A. heterodermus is still unknown and deserves more research. This study highlights the importance of continuous wildlife observations to identify life history traits that may be important in animal behaviour but are challenging to observe in nature.

焦亚硫酸盐金相浸蚀染色试剂的工艺理论探讨

该文实验研究了不同酸度条件下的焦亚硫酸盐溶液的染色效果，并测量了这些溶液的溶液电位随存放时间的变化。试验表明，焦亚硫酸盐试剂的着色速度随溶液酸度的增加而加快，这是由于酸度增加导致溶液电位的负移。但过量的酸化将使溶液急剧分解，而不能着色，随溶液配制后存放时间的增加，溶液电位不断正移，这与溶液的不断分解有关。溶液的搅拌会使溶液电位负移，因此该类试剂在应用时，控制溶液的存放时间与搅拌是重要的。

红莲罐头的工艺研究

通过护色、漂白还原,使红莲罐头的颜色呈亮黄白色。预煮时在预煮液中加入一定浓度的氯化钙,以固定莲子的外部形状使罐头中不致于出现过多的沉淀。经本工艺可得到色泽鲜亮、品质优良的红莲罐头。     

《丘园记》与后印象主义

本文主要将《丘园记》同梵.高的部分作品进行比较,评述《丘园记》体现的后印象主义风格。《丘园记》中,弗吉尼亚.伍尔夫以细腻的文笔,大胆的色彩对比,展现在人们面前的宛如一幅后印象主义油画,表达了伍尔夫对大自然的热爱。《丘园记》中,伍尔夫以丘园为背景,一只蜗牛为线索,四组人物的故事片断为情节完成了一组既联系又独立的画面,而这些充满象征意义的画面则表达了她的内心世界。弗吉尼亚.伍尔夫虽然出身上层社会,却具有一定的社会意识和民主意识。她在《丘园记》中对上层社会的虚伪进行讽刺,同时对处在社会下层的小人物给与同情。这些都使《丘园记》不论从形式上,还是从内容上,都具备了一定的后印象主义特征。
