Species reintroductions and translocations are widely used management interventions to restore locally extinct or augment severely depleted species. In such projects, the human dimension issues that influence success of these conservation encountered at five different stages project life cycle: (1) planning, (2) initiation, (3) implementation, (4) ending stage, (5) post-exit. Overlooking failing consider in any phases could jeopardise translocation project's success. When dimensions included...
The intestinal microbiome is essential to human health and homeostasis, implicated in the pathophysiology of disease, including congenital heart disease cardiac surgery. Improving reducing inflammatory metabolites may reduce systemic inflammation following surgery with cardiopulmonary bypass (CPB) expedite recovery post-operatively. Limited research exists this area identifying animal models that can replicate changes after CPB necessary. We used a piglet model two groups, (n=5) control...
Congenital heart disease (CHD) is the most common birth defect, occurring in roughly 40,000 U.S. births annually. Malnutrition and feeding intolerance (FI) CHD range from 30% to 42% are associated with longer hospitalization increased mortality. Cardiopulmonary bypass (CPB) required for surgical repair of induces a systemic inflammatory response worsening intestinal dysbiosis leading epithelial barrier dysfunction (EBD), possibly contributing postoperative FI. The objective this study was...
Abstract China announced the development of its first 5 national parks in 2021, primary objective which is to conserve natural state and integrity ecosystems. As such, ecosystem services biodiversity levels are crucial assessment factors for parks. For Giant Panda National Park (GPNP), we evaluated ecological sensitivity based on water soil erosion rocky desertification; headwater conservation, conservation; presence giant panda ( Ailuropoda melanoleuca ) sympatric species (e.g., takin [...

One strategy to protect endangered species, and improve the quality of habitat meet needs both wildlife human communities that rely on large protected areas (such as national park), is by zoning its management for multiple uses. We assessed whether multi-use Giant Panda National Park (GPNP) could achieve goal protecting panda population habitat, while also promoting community development. integrate presence data, disturbance distribution, environmental factors evaluate suitability,...
The creation of nature reserves is the most direct way to save endangered species populations and their habitat. Development giant panda (Ailuropoda melanoleuca) reserve network in China was initiated 1960s, though effort create new boomed considerably after year 2000. Given this rapid development protected areas habitats, potential conflicting interests between conservation administrations local economic development, it essential assess role overall network. We utilized data from national...
Giant pandas (Ailuropoda melanoleuca) were historically hunted using dogs and are currently threatened by free-roaming their associated diseases. To better understand the spatial magnitude of this threat, we used a GIS approach to investigate edge effects on giant panda habitat. We first examined two nature reserves with contrasting dog populations: Liziping, many (~0.44/km2), Daxiangling, few (~0.14/km2). Spatial analysis indicated that at Liziping (but not Daxiangling) showed shift in...
Giant pandas (Ailuropoda melanoleuca) are now confined to fragmented habitats in western China, with more than 60 % of individuals inhabiting 63 protected areas. Knowledge the environmental features required by giant is critically important for area spatial arrangement and subsequent assessments. Here we developed a distribution model Tangjiahe Nature Reserve using Ecological Niche Factor Analysis (ENFA) model. We found that less 40 this key reserve high suitability pandas, highly suitable...

Habitat degradation is a major threat to the survival of chiru (Pantholops hodgsonii). Detailed knowledge for habitat conservation in this steppe-dwelling ungulate needed if effective and management strategies are be developed. The distribution potential relative value on regional scale remains unknown, hindering landscape planning. Our aim was identify rank across Chang Tang region Tibetan Plateau. We assessed overall suitability using geographical data, field surveys, information contained...
To achieve reproduction, male solitary mammals need to locate females using chemical communication with high levels of precision. In the case giant pandas, total estrus period was usually 15 days each year, however, successful mating activity is finished within 3 from respective home range. The pattern where multiple males compete for female requires employ efficient systems communicate their phases. verifying whether scent secretions pandas changes by gender and progression, microbiota...
Polyomaviruses infect a wide variety of mammalian and avian hosts with broad spectrum outcomes including asymptomatic infection, acute systemic disease, tumor induction.Viral metagenomics general PCR methods were used to detected viral nucleic acid in the samples from diseased healthy giant pandas.A novel polyomavirus, panda polyomavirus 1 (GPPyV1) nasal cavity dead (Ailuropoda melanoleuca) was characterized. The GPPyV1 genome is 5144 bp size reveals five putative open-reading frames coding...
ABSTRACT The potential threat of domestic dogs to wildlife habitat in China is not widely recognized, despite their large population, lack regulations regarding control, and they pose native species. In a case study 2017, we surveyed villages surrounding Liziping Nature Reserve, the primary site for release captive‐born giant pandas ( Ailuropoda melanoleuca ) into wild. We conducted surveys dog owners assess population size, demographics, free‐roaming status, vaccination sterilization...
Understanding how population density relates to habitat underlies basic ecological theory and is pertinent conservation issues. Chiru (Pantholops hodgsonii) are an endangered steppe-dwelling ungulate endemic the Tibetan plateau. To prepare effective management strategies for this species, we require detailed knowledge of relationship between group size conditions. We surveyed Chang Tang region Tibet used data collected along vehicular line transects record presence chiru. Using niche factor...
