china's battle to save the environment.	by the year 2000 a great green wall of forests may be crossing the country from northwest to northeast, a total of 53 million hectares of green protection from encroaching deserts and erosion, stretching through 12 provinces to increase the nation's forest cover, which now stands at a mere 12.7% of china's territory. soils have been degraded to a critical level only within the past 150 years. at present, about one-sixth of the total land is affected by erosion. in 1988 more than 11 million hecta ...	1989	12291351
early homo and associated artefacts from asia.	the site of longgupo cave was discovered in 1984 and excavated in 1985-1988 by the institute of vertebrate paleontology and paleoanthropology (beijing) and the chongqing national museum (sichuan province). important finds include very archaic hominid dental fragments, gigantopithecus teeth and primitive stone tools. palaeomagnetic analysis and the presence of ailuropoda microta (pygmy giant panda) suggested that the hominid-bearing levels dated to the earliest pleistocene. in 1992, joint chinese ...	1995	7477345
[gap features of subalpine dark coniferous forest in wolong nature reserve].	this paper studied the size structure and formation pattern of gaps and the characteristics of gap makers (gm) in subalpine dark coniferous forests in wolong giant panda nature reserve, sichuan province, china. the results showed that the gap density was 18.5 per hm2, and the area of canopy gap and extended gap accounted for 28.4% and 60% of total forest area, respectively. canopy gap varied from 10 m2 to 1134.7 m2, and expanded gap varied from 84.11 m2 to 1646.3 m2. canopy gaps and expanded gap ...	2004	15707300
temporal changes in giant panda habitat connectivity across boundaries of wolong nature reserve, china.	global biodiversity loss is largely driven by human activities such as the conversion of natural to human-dominated landscapes. a popular approach to mitigating land cover change is the designation of protected areas (e.g., nature reserves). nature reserves are traditionally perceived as strongholds of biodiversity conservation. however, many reserves are affected by land cover changes not only within their boundaries, but also in their surrounding areas. this study analyzed the changes in habit ...	2007	17555215
serosurvey of ex situ giant pandas (ailuropoda melanoleuca) and red pandas (ailurus fulgens) in china with implications for species conservation.	conservation strategies for the giant panda (ailuropoda melanoleuca) include the development of a self-sustaining ex situ population. this study examined the potential significance of infectious pathogens in giant pandas ex situ. serologic antibody titers against canine distemper virus (cdv), canine parvovirus (cpv), canine adenovirus (cav), canine coronavirus (ccv), canine herpesvirus, canine parainfluenza virus (cpiv), toxoplasma gondii, neospora caninum, and leptospira interrogans were measur ...	2007	18229861

microsatellite variability reveals the necessity for genetic input from wild giant pandas (ailuropoda melanoleuca) into the captive population.	recent success in breeding giant pandas in captivity has encouraged panda conservationists to believe that the ex situ population is ready to serve as a source for supporting the wild population. in this study, we used 11 microsatellite dna markers to assess the amount and distribution of genetic variability present in the two largest captive populations (chengdu research base of giant panda breeding, sichuan province and the china research and conservation center for the giant panda at wolong, ...	2009	19222753
phylogenetic study of baylisascaris schroederi isolated from qinling subspecies of giant panda in china based on combined nuclear 5.8s and the second internal transcribed spacer (its-2) ribosomal dna sequences.	the nuclear ribosomal dna (rdna) region spanning 5.8s rdna and the second internal transcribed spacer (its-2) of baylisascaris schroederi isolated from the qinling subspecies of giant panda in shaanxi province, china were amplified and sequenced. sequence variations in the two rdna regions within b. schroederi and among species in the family ascarididae were examined. the lengths of b. schroederi 5.8s and its-2 rdna sequences were 156 bp and 327 bp, respectively, and no nucleotide variation was ...	2012	22402105
treatment and prevention of natural heartworm (dirofilaria immitis) infections in red pandas (ailurus fulgens) with selamectin and ivermectin.	ten of the 48 red pandas in the chengdu research base of giant panda breeding, sichuan province, china, died in 2006 after prolonged periods of depression, weight loss, and mucocutaneous membrane xanthochromia. during postmortem examination, live heartworms were found in the right cardiac ventricles and pulmonary arteries of all 10 animals. selamectin and ivermectin were used for clinical prophylaxis in the remaining red pandas between december 2006 and november 2010. we observed a gradual decre ...	2012	22306025
a new genotype of cryptosporidium from giant panda (ailuropoda melanoleuca) in china.	fifty-seven fecal samples were collected from giant pandas (ailuropoda melanoleuca) in the china conservation and research centre for the giant panda (ccrcgp) in sichuan and examined for cryptosporidium oocysts by sheather's sugar flotation technique. an 18-year-old male giant panda was cryptosporidium positive, with oocysts of an average size of 4.60×3.99 μm (n=50). the isolate was genetically analyzed using the partial 18s rrna, 70 kda heat shock protein (hsp70), cryptosporidium oocyst wall pr ...	2013	23810821
genetic variability of baylisascaris schroederi from the qinling subspecies of the giant panda in china revealed by sequences of three mitochondrial genes.	the present study examined the variations in three mitochondrial (mt) dna sequences, namely cytochrome b (cytb), cytochrome c oxidase subunit 3 (cox3) and nadh dehydrogenase subunit 5 (nad5), among baylisascaris schroederi isolates from the qinling subspecies of the giant panda in shaanxi province, northwestern china. no differences in length were detected in the three mt fragments from different isolates. the intra-specific sequence variations within all b. schroederi samples were 0-2.6% for pc ...	2014	23656289
prevalence and molecular characterization of cryptosporidium in giant panda (ailuropoda melanoleuca) in sichuan province, china.	cryptosporidium spp. have been extensively reported to cause significant diarrheal disease in humans and domestic animals. on the contrary, little information is available on the prevalence and characterization of cryptosporidium in wild animals in china, especially in giant pandas. the aim of the present study was to detect cryptosporidium infections and identify cryptosporidium species at the molecular level in both captive and wild giant pandas in sichuan province, china.	2015	26108274
