A short note on extractive foraging behavior in gray snub‐nosed monkeys

Extractive foraging (EF) involves the exploitation of hidden or embedded foods, generally any food that is not visible to the naked eye. Therefore, EF is particularly important for survival in marginal habitats as it provides seasonal fallback foods in low food availability seasons. Although many studies consider primates’ EF behavior and category, colobine species are usually categorized as non‐extractive foragers and few studies quantitatively examine their EF behavior. In this study, we examined the EF behavior of one colobine species, the gray snub‐nosed monkey (Rhinopithecus brelichi), at Yangaoping in Fanjingshan National Nature Reserve, Guizhou. We recorded 6 categories of EF behaviors. The most frequently sought‐out foods were seeds, young bamboo and invertebrates. Extracted foods accounted for an average of 26.02% of feeding records. As the monkey engages in little EF behavior in the winter when the food availability is low, these results seem to do not support the hypothesis that EF serves to secure additional resources during lean times in marginal or seasonal habitats. According to these findings, we suggest R. brelich should be considered as an extractive forager. Our study also highlights the need for increased representation of colobines in the EF literature to better inform the discussion concerning its link to primate brain evolution.     

通海县生物防火隔离带营建及其防火性能研究

2002～2005年,在通海县河西、九街、四街镇人工营造以旱冬瓜、川滇桤木为主栽树种的生物防火隔离带,共计21条,宽25m,总长36km.对所营造防火林带的防火效果进行调查分析,结果认为,防火林带树木生长讯速,抗火、耐火性强,有较好的阻火、隔火、断火功能,且节约经费,营造技术较为成熟,可以推广应用.

Effect of Cardinium Infection on the Probing Behavior of Bemisia tabaci (Hemiptera: Aleyrodidae) MED

Facultative endosymbionts can affect the growth, physiology, and behavior of their arthropod hosts. There are several endosymbionts in the invasive whitefly Bemisia tabaci Mediterranean (MED, Q biotype) that influence host fitness by altering stylet probing behavior. We investigated the probing behavior of B. tabaci MED infected with the facultative endosymbiont Candidatus Cardinium hertigii (Cardinium (Sphingobacteriales: Flexibacteraceae)). We generated genetically similar Cardinium-infected (C^*+) and uninfected (C^-) clonal sublines and analyzed the probing behavior of newly emerged adult on cotton (Malvales: Malvaceae), Gossypium hirsutum L., using electropenetrography (EPG). The C^- subline demonstrated a longer duration of E2 (2.81-fold) and more events of E2 (2.22-fold) than the C^*+ subline, indicating a greater level of sustained ingestion of plant phloem. These findings provide insight into the fitness costs (fitness of a particular genotype is lower than the average fitness of the population) of the Cardinium-infected B. tabaci.

南蝠捕食行为及其对稻田虫害发生的影响

为了解南蝠(Ia io)在维持稻田生态系统稳定性中的作用,采用粪便分析和直观法,研究了南蝠的捕食行为及其对稻田虫害发生的影响。结果表明:南蝠是控制农田害虫的有效天敌之一,在其捕食区域内稻田病虫害较轻,2～3km半径区域水稻的平均产量比6～7km半径区域增产98.2kg/667m2;南蝠的食物组成除鸟类外,还有鞘翅目、鳞翅目、半翅目、直翅目、膜翅目和蜱螨等昆虫/生物,多数种类昆虫均是水稻害虫或病害的传播者。南蝠在维护稻田生态系统稳定性和提高农作物产量方面具有重要的作用。
