Multi-sectoral Participatory Urban Forestry Development in Philippines Metropolitan Manila

The Luntiang Kamaynilaan Project (Metro ManilaGreening Project) launched in 1988 planted trees inmajor thoroughfares, center islands, school premisesand other idle public lands, was basically a governmenteffort. When the funds ran out, the project also fizzledout. In both projects however, it is evident that the keyfactor is peoples participation.Gaining lessons from the past two projects, thegovernment established a collaborative effort ofgovernment and non-government organizations.

Nutrient digestibility of angling baits for carp, Cyprinus carpio, with implications for groundbait formulation and eutrophication control

Abstract  To evaluate the suitability of angling groundbaits as a fish feed and the potential for nutrient loss, the macronutrient digestibility of four groundbaits was investigated in carp, Cyprinus carpio L., using a sieving method of faeces collection and chromic oxide. Apparent digestibility coefficients (ADCs) of protein and lipids were >80% for all angling baits. ADCs of nitrogen-free extracts and phosphorus (P) differed significantly between the test diets, probably because of divergent feed compositions and ingredient treatments. The generally high digestibility estimates indicated that fish feeding on angling groundbait will benefit from this food source. The differences in nutrient digestibility suggested that type of groundbait and ingredient used will have a major effect on potential eutrophication and fish production caused by groundbaiting. The principle of groundbaits to protect the environment should be to minimise the P-content of the groundaits and maximising P-digestibility and P-retention efficiency.

矮壮素对高羊茅生长特性影响的研究

试验采用0.8,1.0,1.2 mg/g 3种浓度的矮壮素(CCC)对草坪草高羊茅Festuca arundinacea进行处理,结果表明:3种浓度的矮壮素对高羊茅生长均产生不同程度的影响,其中 0.8 mg/g矮壮素处理使高羊茅株高、修剪量明显降低.综合考虑药效及成本,建议在实际生产中应用0.8 mg/g的矮壮素浓度.

GIS在生态土地分类中的作用

This paper depicted the physiographic landscape features and natural vegetation situation of study area (the eastern Jilin Province), and expatiates the definition, basic characters and its development of Ecological Land Classification (ELC). Based on the combination of relief map, satellite photography for study area and vegetation inventory data of 480 sample sites, a 5-class and a 15-class ecological land type map was concluded according to 4 important factors including slope, aspect, vegetation and elevation. Ecological Classification System (ECS) is a method to identify, characterize, and map ecosystems. The Ecological Land Type (ELT) was examined and applied initially in eastern Jilin Province. Foundation item: This paper was supported by Chinese Academy of Sciences “100 people” project and the Open Research Station of Changbai Mountain Forest Ecosystem.

犬腺病毒SY-45株不同大小蚀斑特性研究

应用蚀斑方法将SY－45毒株经过3次蚀斑纯化直到蚀斑大小相对稳定。从不同大小的蚀斑中挑选出三种蚀斑，大斑直径约3mm(简称LP）、中斑约2mm(简称MP）、小斑约1mm(简称SP）。分别在MDCK细胞上增殖并进行了三种不同大小斑毒对犬的毒力、免疫原性和在MDCK细胞上产毒量比较，以筛选最佳的疫苗株，试验结果表明用不同大小蚀斑病毒大剂量人工感染易感犬后，所有的试验犬临床症状和病理解剖学和病理组织学表现均正常；对挑选的4窝CAV HI抗体效价小于等于1：2的健康幼犬进行免疫试验，测定血清的中和抗体效价和血凝抑制抗体效价，结果表明：大斑毒的免疫原性要稍高于中斑毒，而明显高于小斑毒；不同大小蚀斑毒在MDKC细胞上产毒量差异很大，大斑毒可达10^7TCID50／mL、小斑毒达10^6TCID50／ml、小斑毒达10^4.5TCID^50/mL。综合所有试验结果表明：大斑毒株具有产毒量高、安全性好、免疫原性强的优点，是较为理想的疫苗株。

水飞蓟对动物机体免疫功能的影响研究

将小鼠分为四组，分别饲喂１０％水飞蓟、２０％水飞蓟、环磷酰胺（０．０１ｇ／ｋｇ）和空白对照（常规饲料），研究对小鼠免疫功能的影响。实验结果证明，水飞蓟各剂量组能增高小鼠外周血白细胞数目（Ｐ＜０．０１、０．００１）；提高小鼠腹腔巨噬细胞的吞噬率（Ｐ＜０．００１，０．００１）及吞噬指数（Ｐ＜０．０５、０．００１）并随剂量加大有增强的趋势；能促进小鼠淋巴细胞转化，提高淋巴细胞转化百分率（Ｐ＜０．０１、０
