Mating behaviour,nympho-imaginal development and description of a new Mesabolivar species (Araneae: Pholcidae) from the Brazilian dry forest

A new species of Mesabolivar is described from Brazilian forests: Mesabolivar delclaroi. The mating behaviour, postembryonic development, number of egg sacs and eggs, birth rate, number of instars, developmental time until adulthood, sex ratio and size of cephalothorax (per instar) were recorded. The sexual behaviour was described and categorized into four steps: courtship, pre-copulation, copulation and post-copulation. After hatching, individuals presented five instars until maturity. The mean number of eggs (42 ± 16.6) and live births (31.5 ± 3.4) of the first egg sac were significantly greater than that of a second one (23.8 ± 3.8, and 19.25 ± 3.9, respectively). The developmental time from birth to adulthood (130.8 ± 9.6 days) did not differ significantly between egg sacs produced (128.61 ± 11.1). The size of the cephalothorax did not differ among adults or between sexes. The sex ratio revealed a shift in favour of females (4: 3).     

Studies on gorgoderid digeneans from Australian and Assian Freshwater fishes

Pseudophyllodistomum gen. nov. is proposed for a section of Phyllodistomum Braun, 1899. The new genus is distinguished by the simple form of the uterus, the eggs which reach over 60 μm long in length, the saccular excretory bladder, the 2[3 + 3 + 3) + (3 + 3 + 3)] = 36 flame-cell formula, the metacercaria which may have fully developed genitalia and is parasitic in decapod crustaceans, the use of corbiculid bivalves as first intermediate hosts, and the cercaria which has a long tail not enclosing the cercarial body. Two species, P. johnstoni sp. nov. and P. murrayense sp. nov., are described from Australian freshwater fish and five new combinations of previously described Phyllodistomum species from Asian freshwater fish are proposed — P. macrobrachicola (Yamaguti, 1934) comb. nov., P. lesteri (Wu, 1938) comb. nov., P. srivastavai (Rai, 1964) comb. nov., P. lucknowense (Pandey, 1970) comb. nov. and P. mingense (Tang, 1985) comb. nov. The first intermediate host of P. johnstoni is a Corbiculina species. The long-tailed cercariae infect the gonads of palaemonid prawns, Macrobrachium spp., in which they grow to unencysted metacercariae which may have fully developed genitalia. The metacercaria of P. murrayense also infects a Macrobrachium species. The evolution of the Gorgoderinae is discussed and it is suggested that, prior to the erection of Pseudophyllodistomum, Phyllodistomum may have encompassed as many as five different phylogenetic lines, each with similar adult morphology but distinguishable by life-cycle characters. It is postulated that more study will lead to further division of Phyllodistomum.

低碳生活的非线性规划

文章首先在查找资料的基础上充分认识低碳生活,给出了低碳生活的定义,并给出一组关于各项生活行为的单位消耗量的碳排放量指标和消费支出的数据。随后建立了以最低碳排放量为目标的非线性规划模型。考虑到在减少碳排放的同时要兼顾生活质量的保证,利用模糊方法建立各类消费支出的生活质量模糊隶属函数,保证生活质量不低于人均生活质量水平。通过优化求解,得到一组满足要求的各项生活行为的需求值。最后,在分析结果的基础上提出了家庭日常生活减少碳排放量的措施,为指导低碳生活的发展提出一些建议。
