Progress of Ecological Restoration Research Based on Bibliometric Analysis.

With the deterioration of the global/regional ecological environment, ecological restoration plays an important role in sustainable development. However, due to the differences in research methods, objectives, and perspectives, the research results are highly diverse. This makes it necessary to sort the publications related to ecological restoration, clarify the research status, grasp the research hotspots, and predict the future research trends.

[Habitat selection and use of Francois's langurs (Trachypithecus francoisi) in Guangxi Province, Fusui area].

To explore the influence of habitat fragmentation on the ecology of the Francois's langur (Trachypithecus francoisi), data on habitat use were collected from a group of Francois's langurs living in an isolated hill in the Fusui Rare Animal Nature Reserve, Guangxi Province, from March to December 2001. To identify the effect of human activities on vegetation, 10 vegetation quadrats were sampled in the habitat, including 5 on the slopes with more human disturbance, and 5 on the hill-tops with less human disturbance. Because of human destruction, not only the number of plant species, diversity and density, but also the densities of preferred foods for Francois's langurs were less on the slope than those on the hill-top.

A novel piezoelectric quartz crystal immnuosensor based on hyperbranched polymer films for the detection of alpha-Fetoprotein.

This paper reports a novel piezoelectric quartz crystal immnuosensor based on hyperbranched polymer films for the detection of alpha-Fetoprotein. In this strategy, the sensing interfaces consist of a primary cystamine monolayer assembled onto Au electrodes associated with the piezoelectric quartz crystal. The monolayer is further modified with a new hyperbranched polymer which was synthesized through direct polycondensation of monomer 5-[3-(4-aminophenyl) propionylamino] isophthalic acid.

Feeding strategy of François' langur and white-headed langur at Fusui, China.

We investigated the diet of a group of François' langur inhabiting a forest fragment between August 2002 and July 2003 to add to our knowledge of behavior and ecology of this langur. Our objective was to study whether the François' langur would adopt a feeding strategy similar to the white-headed langur in the same nature reserve. Data indicated that a total of 37 plant species were eaten by François' langur; however, only ten species accounted for 90% of the total feeding time.

Ranging behavior of the François' langur (Trachypithecus francoisi) in the Fusui Nature Reserve, China.

Data on activity budgets and ranging patterns were collected from March to December 2001 for one group of François' langurs (Trachypithecus francoisi) inhabiting a forested part of the Fusui Nature Reserve, Guangxi province, China. Our results indicate that the total size of the home range of the study group during the study period was 19 ha. The majority of their activities (52%) occurred within a small area, 22%, of their home range, and was concentrated in or near quadrats containing their sleeping sites, which may reduce the time and energetic cost of travel.
