Pattern of play behavior in infant (age 1 to 12 months) white-headed langurs in limestone forests, southwest China.

Play behavior is a significant trait of immature nonhuman primates (hereafter primates) that plays an important role in sensory, locomotor, socio-cognitive, and developmental processes. It has been suggested that the function of play is to practice and improve motor skills related to foraging, avoiding predators, attracting mates, raising offspring, and strengthening the skills needed for the formation and maintenance of social bonds. From September 2009 to August 2010, we investigated the play behavior of 1-12 month-old infant white-headed langurs () a Critically Endangered primate species endemic to China.

Complete mitogenome of the Common Koel Linnaeus 1758 (Aves: Cuculidae).

The Common Koel Linnaeus 1758, belongs to the family Cuculidae and order Cuculiformes. This omnivorous bird exhibits obligate nest parasitism. Here, the complete mitogenome of was determined and phylogenetically compared with those of other Cuculidae species.

First determination and analysis of the complete mitochondrial genome of X-ray tetra (Ulrey, 1894) (Actinopteri, Characidae).

The complete mitochondrial genome of the X-ray tetra (, Ulrey, 1894) was determined by using next-generation sequencing technology, and its mitochondrial genome characteristics were analyzed. The sequence total length was 16,753 bp, and the A + T content was 57.44%.

Forest seasonality shapes diet of limestone-living rhesus macaques at Nonggang, China.

Limestone forests are an unusual habitat for primates, but little information is available for the genus Macaca in such habitats, making a comparative understanding of extant limestone primates' behavioral adaptation incomplete. We collected data on the diet of rhesus macaques (Macaca mulatta) in a limestone habitat at Nonggang Nature Reserve, southwestern Guangxi, China, and examined the effects of forest seasonality on their diet. Our results indicated that a total of 114 species of plants are consumed by macaques.

Dietary adaptations of Assamese macaques (Macaca assamensis) in limestone forests in Southwest China.

Limestone hills are an unusual habitat for primates, prompting them to evolve specific behavioral adaptations to the component karst habitat. From September 2012 to August 2013, we collected data on the diet of one group of Assamese macaques living in limestone forests at Nonggang National Nature Reserve, Guangxi Province, China, using instantaneous scan sampling. Assamese macaques were primarily folivorous, young leaves accounting for 75.
