Introducing TropiCam‐AI: A taxonomically flexible automated classifier of Neotropical arboreal mammals and birds from camera‐trap data

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 4, Page 1235-1247, April 2026.
Abstract Rapid, accurate assessment of arboreal vertebrates in tropical forests remains a bottleneck for large‐scale biodiversity monitoring, due to the challenges and effort associated with traditional survey methods. To bridge this gap, arboreal camera‐trapping is emerging as a promising way to observe otherwise elusive species, opening new avenues ...

Genomics Insights Into High‐Latitude Adaptation of Tibetan Macaques

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
Tibetan macaques exhibit unique adaptations to cold, high‐latitude environments, including shortened tails and enhanced fat storage. Genomic analyses reveal a species‐specific TBX6 mutation linked to tail reduction and selection on lipid metabolism genes.

Present state of evolution and systematics of Platyrrhiny.

open access: yesAnthropological Science, 1995
南米大陸の熱帯雨林に生息する広鼻猿類の系統進化に関する研究は, ここ十数年の相次ぐ化石種の発見と分子生物学的手法の発展により飛躍的に進展している。現在の主な論点は, マーモセット類•サキ類•クモザル類 (ホエザルを含む) の大きな3つのグループと, 残りの4属 (リスザル•ヨザル•ティティモンキー•オマキザル)との系統的な関係である。特に後4者の系統的な位置に関しては, 古生物学的な解析,現生種の形態学的解析, 分子生物学的解析のいずれも決定的な結論を出すに至っていない. 広鼻猿類の進化の初期段階で, 非常に短い時間に急速に互いに分岐したのではないかと思われる。

To be or Not to be Hybrids? A Case‐Study in an Allochthonous Population Involving Illegal Introductions of the Endangered Golden‐Headed and Golden Lion Tamarins

open access: yesAmerican Journal of Primatology, Volume 88, Issue 1, January 2026.
Genetic analyses of an allochthonous population of Leontopithecus, illegally introduced into an area of the Brazilian Atlantic Forest in Rio de Janeiro, did not detect signs of hybridization. This data provides crucial information to support conservation efforts and prevent new threats to the endangered lion tamarins. ABSTRACT Allochthonous species can

Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae)

open access: yesAmerican Journal of Primatology, Volume 88, Issue 1, January 2026.
Spectral parameters of vocalizations distinguish lion tamarin species. Peak frequency, center frequency, and frequency at 5% and 95% were the most informative measures for separating species, with the trill being the vocalization that showed the most differences, and Leontopithecus caissara being the most distinct species of all.

Responses of wild titi monkeys, Callicebus coimbrai (Primates: Platyrrhini: Pitheciidae), to the habituation process

open access: yesZoologia (Curitiba), 2010
Adequate habituation of free-ranging subjects is essential for any field study, but is generally unsystematic. Here, attempts to habituate three titi monkey (Callicebus coimbrai Kobayashi & Langguth, 1999) groups are described, and factors determining ...

Variación heterocromática del cariotipo, en el Género Cebus que habita en Colombia

open access: yesActa Biológica Colombiana, 2001
El entendimiento de la diversidad de los primates es esencial para establecer prioridades en losplanes de su conservación, la taxonomía precede la conservación y en la mayoría de los génerosde los primates Platyrrhini, la taxonomía aún es controvertida. (

The Scent Gland Microbiomes of Wild Tamarins Provide New Insight Into Microbial Contributions to Olfactory Communication

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
Our study investigated the microbiomes of suprapubic and sternal scent glands in two wild tamarin species to explore their putative roles in odor production and communication. Using metagenomic sequencing, we identified 18 odor‐associated microbial taxa and 26 related metabolic pathways, finding significant differences in microbial diversity and ...

The prion protein and New World primate phylogeny

open access: yesGenetics and Molecular Biology, 2004
The PrP C prion protein contains 250 amino acids with some variation among species and is expressed in several cell types. PrP C is converted to PrP Sc by a post-translational process in which it acquires amino acid sequences of three-dimensional ...

Non‐Carious Cervical Lesions in Wild Primates: Implications for Understanding Toothpick Grooves and Abfraction Lesions

open access: yesAmerican Journal of Biological Anthropology, Volume 188, Issue 2, October 2025.
ABSTRACT Objectives In clinical settings, non‐carious cervical lesions (NCCLs) are often linked to abrasion, erosion, abfraction, or a combination of these factors. In archaeological and paleontological remains, the most common NCCL is the “toothpick groove,” yet little is known about the occurrence of these and other NCCLs in wild non‐human primates ...
