Ecology and Evolution, Volume 15, Issue 10, October 2025.Jaguars in the northern end of their distribution have recently become the center of conservation efforts; however, the State of Chihuahua has been underrepresented in monitoring projects. We present five new records of jaguars in high altitudes as well as the first evidence of two jaguars exhibiting cooperative behavior in Mexico.

No need to replace an “anomalous” primate (Primates) with an “anomalous” bear (Carnivora, Ursidae)
ZooKeys, 2015 By means of mitochondrial 12S rRNA sequencing of putative “yeti”, “bigfoot”, and other “anomalous primate” hair samples, a recent study concluded that two samples, presented as from the Himalayas, do not belong to an “anomalous primate”, but to an ...

Ecology and Evolution, Volume 15, Issue 10, October 2025.We used direct observations, camera traps, and environmental DNA (eDNA) to identify secondary consumers of sap from wells created by red‐naped (S. nuchalis) and Williamson's (S. thyroideus) sapsuckers among three groups of shrubs and trees in south‐central Colorado, USA.

Enamel Structure of Arctoid Carnivora: Amphicyonidae, Ursidae, Procyonidae, and Mustelidae [PDF]
Journal of Mammalogy, 2001 Enamel of several fossil and recent arctoid carnivores was studied with light and scanning electron microscopy. As in other carnivorans, 3 types of Hunter-Schreger bands (HSB) were observed: undulating, acute-angled, and zigzag HSB, which differ in their 3-dimensional complexity.

野生动物学报, 1987 研究大熊猫的免疫分类学性状,并讨论大熊猫在解剖学、遗传学和分子生物学方面的特征,认为大熊猫与熊类亲缘关系密切是无可辩驳的。主张大熊猫更为适宜的分类地位是并入熊科（Ursidae）,再立大熊猫亚科（A11uropodinae）。问题的提出关于大熊猫和小熊猫在分类学上的地位,一百多年来一直是生物学上一个难解之谜。虽然有不少学者,尤其是我国的学者把大熊猫划为独立的一科,把小熊猫划入浣熊科 （Procyonidae）,但是纵观发表的50篇论文表明,把大熊猫分为熊科（Ursidae）、浣熊科和自成大熊猫科 ...

Ecotone Might Provide Key Refugium for Sky Island Mammals in the Southern Appalachian Mountains
Ecology and Evolution, Volume 15, Issue 10, October 2025.Sky islands are among the most biodiverse ecosystems in the world but face a disproportionately high threat from climate change. We examined the spruce‐fir–northern hardwood ecotone as a possible refugium for mammals in the Southern Appalachian red spruce (Picea rubens)–Fraser fir (Abies fraseri) sky islands.

Occurrence and structure of epipharyngeal pouches in bears (Ursidae)
Journal of Anatomy, 2001 The infrequent mention of epipharyngeal pouches occurring in some species of bears indicates the scarcity of morphological and functional knowledge about these structures. In order to provide precise morphological data on the structure of these remarkable formations and to verify their taxonomic utility, the pharyngeal regions of 1 spectacled bear and ...
