As an endemic and critically-endangered wildlife species in China,the giant panda(Ailuropoda melanoleuca)has attracted widespread attention from all sectors of society regarding its survival status.In this study,the impact of earthquake-dameged areas on the distribution and activities of giant pandas in the Qionglai Mountains was analyzed by comparing data from two giant panda surveys conducted in the Qionglai Mountains of Sichuan Province and combining with remote sensing(RS)data from relevant regions.The results indicated that there was only a small area of overlap between the earthquake-damaged areas and giant panda activity trace points.The main earthquake-damaged areas were distributed at elevations(3,500-4,100 m)higher than the primary elevation range of giant panda distribution(1,700-3,100 m).In the Wolong Nature Reserve,no major earthquake damage was observed in the central section east of Provincial Highway 303 with relatively more giant panda activities.Within the Caopo Nature Reserve,the earthquake-damaged areas were mostly concentrated in the northeastern corner and along the border with the Wolong Nature Reserve.However,no large-scale giant panda activity traces were detected in these areas during either of the two surveys.Overall,the range of giant panda activities showed no signs of decline.Therefore,the impact of earthquakes on giant panda activities remains limited. 展开更多

Giant panda writing is a classic form of thematic nature writing.Since the scientific discovery and the popularization of the giant panda by naturalists,this writing tradition has spanned nearly a century.Throughout this process,Chinese giant panda writing has developed its own distinct characteristics.Western giant panda writing encompasses genres such as scientific essays,fieldwork notes,and documentary works.Within Chinese giant panda writing,reportage,popular science works,and comprehensive,systematic documentary works all have representative authors and texts.In recent years,IP-oriented giant panda books have shown notable performance.While Chinese giant panda writing exhibits diverse types and perspectives,its scientific rigor,informative value,and innovative expression still require enhancement.As a form of thematic nature writing,giant panda writing provides valuable insights for writings on other subjects. 展开更多

Applying visual grammar theory,this study examines representational,interactive,and compositional meanings of the giant panda in Western media cartoons related to China from 1999 to the present.Distinct phases in the panda’s representation were identified and illustrated by cases of cartoons in major Western media.These phases trace shift of panda cartoon image from a symbol of peace and friendliness to a politicized emblem of China’s international stance.Key visual trends,such as transitivity,color symbolism,scale enlargement,and increasing compositional complexity,embody the panda’s role in shaping China’s global image and its function in international discourse.These trends reflect the panda’s transformation into a contested symbol,which mediates between China’s self-representation and Western perceptions of its geopolitical rise.By situating the analysis within the context of China’s growing global influence,this study contributes to visual and media studies,demonstrating how cultural symbols are recontextualized to reflect and shape geopolitical narratives. 展开更多

The role that visual discriminative ability plays among giant pandas in social communication and individual discrimination has received less attention than olfactory and auditory modalities.Here,we used an eye-tracker technology to investigate pupil fixation patterns for 8 captive male giant pandas Ailuropoda melanoleuca.We paired images(N=26)of conspecifics against:1)sympatric predators(gray wolves and tigers),and non-threatening sympatric species(golden pheasant,golden snub-nosed monkey,takin,and red panda),2)conspecifics with atypical fur colora-tion(albino and brown),and 3)zookeepers/non-zookeepers wearing either work uniform or plain clothing.For each session,we tracked the pan-da's pupil movements and measured pupil first fixation point(FFP),fixation latency,total fixation count(TFC),and duration(TFD)of attention to each image.Overall,pandas exhibited similar attention(FFPs and TFCs)to images of predators and non-threatening sympatric species.Images of golden pheasant,snub-nosed monkey,and tiger received less attention(TFD)than images of conspecifics,whereas images of takin and red panda received more attention,suggesting a greater alertness to habitat or food competitors than to potential predators.Pandas'TFCs were greater for images of black-white conspecifics than for albino or brown phenotypes,implying that familiar color elicited more interest.Pandas reacted differently to images of men versus women.For images of women only,pandas gave more attention(TFC)to familiar combinations(uniformed zookeepers and plain-clothed non-zookeepers),consistent with the familiarity hypothesis.That pandas can use visual perception to discriminate intra-specifically and inter-specifically,including details of human appearance,has applications for panda conservation and captive husbandry. 展开更多

The giant panda(Ailuropoda melanoleuca),as a rare and endangered wild animal in China,has attracted wide attention from all walks of life.In this study,the changes of disturbances in the habitat of giant panda population in the Qionglai Mountains of Sichuan Province were studied and analyzed by comparing the data of two giant panda surveys in Qionglai Mountains and combining with the remote sensing(ES)data of related areas.The results showed that the number of general disturbances in the habitat of giant pandas in Qionglai Mountains greatly reduced in 10 years,and the types of disturbances also changed greatly.The logging disturbance which was most distributed in the third survey almost disappeared in the fourth survey,and the grazing disturbance in the habitat became the disturbance type with the highest encounter rate.The density of human activities in the whole mountain system greatly decreased,but the scope was slightly expanded.Baoxing and Lushan were areas with high density of giant panda activities,and the number of various human activities was relatively large.In the two surveys,the avoidance effect of giant pandas on logging,grazing,roads,hunting and other disturbances showed significant differences.The activity density of local small populations of giant pandas in Qionglai Mountains changed. 展开更多

The general aim of this study is to find the relationship between the panda distribution and human activities. Comparison of the potential panda habitat and the real panda distribution shows a difference between them. Seven human activities were identified and analyzed. They are settlements, farming, road construction, firewood collection, timber production, mining and Chinese medicinal plant collection. The spatial distributions of these activities were characterized. The analysis of their spatial distributions and the pandas' habitat and distribution revealed that there is a relation existing between the human activities and the panda distribution, and the Giant Pandas have disappeared from the areas where the human activities are concentrated. GIS is the main tool used in this study to collect, store, retrieve, transform and present the spatial data of human activities and panda habitat and distribution in Wolong Nature Reserve. 展开更多
