Mitigating Effects of Nest Structure on Predation Risk in Hainan Partridge (<i>Arborophila ardens</i>). [PDF]

Ecol Evol
Enclosed nest structures can disrupt predator search efficiency and reduce predation risk. Predation rate in the uncovered group was significantly higher than that in the covered group. Our study highlights the functional limitations of nest‐structure evolution within complex predation environments.

Habitat restoration is the greatest challenge for population recovery of Hainan gibbons (Nomascus hainanus) [PDF]

Integrative Zoology, 2022
AbstractHainan gibbons are among the world's most critically endangered primates, with a remaining population of only 35 individuals distributed across 5 social groups in the Bawangling Branch of the Hainan Tropical Rainforest National Park, China.

Automatic detection for the world's rarest primates based on a tropical rainforest environment

Global Ecology and Conservation, 2022
Hainan gibbons are the most endangered primates in the world and are at risk of extinction at any time. Infrared trigger camera technology is one of the most effective means at present, however, the data obtained are characterized by massive ...

Evaluation of the Effectiveness of Regulatory Measures for the Use of Natural Ecological Space Based on the Remote Sensing-Driven PLUS-InVEST Model: A Case Study From the Central Mountainous Area of Hainan Island. [PDF]

Ecol Evol
Unreasonable reclamation and construction activities have led to a decline in habitat quality and loss of biodiversity in tropical rainforest areas, especially in key biodiversity regions globally. In this study, the remote sensing data‐driven PLUS‐InVEST coupled model was used to evaluate and forecast the habitat quality and degree of degradation in ...

Automated Detection of Gibbon Calls From Passive Acoustic Monitoring Data Using Convolutional Neural Networks in the "Torch for R" Ecosystem. [PDF]

Ecol Evol
Our paper presents a workflow utilizing deep learning with convolutional neural networks in the “torch for R” ecosystem for automated detection of gibbon calls from passive acoustic monitoring data. We compare six CNN architectures, assessing their performance on data sets of female calls from two gibbon species.

Home Range of the Endangered Beale's Eyed Turtle (<i>Sacalia bealei</i>) and the Implications for Conservation. [PDF]

Ecol Evol
This study examines the home range and spatial ecology of the endangered Beale's Eyed Turtle (Sacalia bealei) in China using radiotelemetry. We found that females had significantly larger home ranges during the breeding season compared to males, while no sex‐based differences were observed in the non‐breeding season. Our results underscore the species'

Mitogenomes of museum specimens provide new insight into species classification and recently reduced diversity of highly endangered Nomascus gibbons. [PDF]

Integr Zool
Our findings reveal that the western black crested gibbon (Nomascus concolor) did not divide into different subspecies, and the relatively low level of genetic diversity emphasizes the importance of monitoring this indicator for vulnerable wildlife.

Food plant diversity determines home range area and formation of a new family group of the world’s rarest primate

Frontiers in Environmental Science, 2022
Global primates are endangered, and thus it is important to know the determinants of primate population dynamics. It is widely reported that food plant diversity and nutrients are key determinants of many primate population dynamics.

Hainan Gibbons (Nomascus hainanus), the Most Threatened and Rarest Primate in the World

Journal of Biomedical Research & Environmental Sciences, 2022
Gibbons (Hylobatidae) are exclusively arboreal small apes only inhabiting in tropical rainforests of Southeast Asia [1]. Gibbons in Nomascus have 52 chromosomes and adult males and females are almost the same body size.

The Genetic Status of the Critically Endangered Hainan Gibbon (Nomascus hainanus): A Species Moving Toward Extinction. [PDF]

Front Genet, 2020
The Hainan gibbon (Nomascus hainanus), once widespread across Hainan, China, is now found only in the Bawangling National Nature Reserve. With a remaining population size of 33 individuals, it is the world’s rarest primate. Habitat loss and fragmentation are the primary drivers of Hainan gibbon population decline.
