The current status of the Hainan black-crested gibbon Nomascus sp. cf. nasutus hainanus in Bawangling National Nature Reserve, Hainan, China [PDF]

Oryx, 2004
The Hainan black-crested gibbon Nomascus sp. cf. nasutus hainanus is on the verge of extinction. Following studies in the late 1980s and early 1990s only limited observations were made of the remaining population in the Bawangling National Nature Reserve on Hainan Island, China, and the most optimistic estimation of the population size was 23 ...

Vocal Diversity and Taxonomy of Nomascus in Cambodia [PDF]

, 2005
It is usually thought that Nomascus gabriellae is the only Nomascus sp. in Cambodia. We studied vocal diversity among different wild popula-tions of Nomascus in Cambodia to assess their taxonomic relationships and to examine whether their vocal patterns ...

Simulated soundscapes and transfer learning boost the performance of acoustic classifiers under data scarcity

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 322-338, February 2026.
Abstract The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are

Continuous Audio‐Visual Sensor Monitoring Is More Effective Than Human Observers for Detecting Moor Macaques

American Journal of Primatology, Volume 88, Issue 1, January 2026.
Camera traps and PAM outperformed human transects in detecting moor macaques: sensors overcame point transect detectability after 2 days survey. Combining both audio‐visual methods achieved highest detectability, supporting audio‐visual sensors as essential tools for primate monitoring in tropical forests. ABSTRACT The number of species threatened with

Construction of an Ecological Security Pattern for the National Park of Hainan Tropical Rainforest on the Basis of the Importance of the Function and Sensitivity of Its Ecosystem Services

Land
The National Park of Hainan Tropical Rainforest (NPHTR) plays the crucial role of an ecological barrier for Hainan Island. It also serves as a valuable repository of tropical biological heritage for the world.

Complete Mitogenomes of the Critically Endangered Hainan Gibbon (Nomascus hainanus) Reveal Very Low Mitochondrial Diversity and Two Major Maternal Clades

Animals
The Hainan gibbon (Nomascus hainanus) is one of the most threatened primates, yet its mitochondrial haplotype diversity and genealogy remain poorly understood. This study investigated mitochondrial haplotype structure, genealogical history, and selective

海南热带雨林国家公园海南长臂猿食源植物组成

野生动物学报, 2021
2019年4—10月，利用访问调查法和样方调查法对海南长臂猿（Nomascus hainanus）食源植物展开调查，确定了海南长臂猿食源植物组成及其季节性变化。研究表明，海南长臂猿采食的食源植物有166种，隶属于52科99属。在雨季（5—10月），海南长臂猿食源植物有47科88属148种。在旱季（11月至翌年4月），海南长臂猿食源植物有39科61属90种。在雨季，海南长臂猿可采食成熟果实的植物种类较多，相对更容易获得食物。而在旱季能够取食果实的植物种类减少，结果量较低、且分布不集中 ...

Human Fragmentation Effects Are Genetically Detectable After 6 Years in an Island‐Endemic Plant

Ecology and Evolution, Volume 15, Issue 5, May 2025.
We provide direct evidence that anthropogenic infrastructures such as reservoirs and expressways have been capable of increasing genetic differentiation and, thus, modifying the phylogeographical pattern of Primulina heterotricha in just a six‐year period (two generations of the plant). ABSTRACT Anthropogenic disturbances have long been acknowledged to
