Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

Boreas, EarlyView.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.

Microbial Contributions to Primate Reproduction

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 1, March 2026.
ABSTRACT Reproduction is a complex process, and microbes play a far greater role than previously imagined. This review explores the ways that microbiomes influence the rich tapestry of reproductive processes and outcomes within the primate lineage, including pre‐copulatory and post‐copulatory mechanisms.

The next widespread bamboo flowering poses a massive risk to the giant panda [PDF]

, 2019
The IUCN Red List has downgraded several species from “endangered” to “vulnerable” that still have largely unknown extinction risks. We consider one of those downgraded species, the giant panda, a bamboo specialist.

The American Black Bear (Ursus americanus) as an Apex Predator: Investigating the Ecological Role of the World's Most Abundant Large Carnivore

Mammal Review, Volume 56, Issue 1, March 2026.
Black bears as apex predators. American black bears can (1) produce top‐down effects on ungulates equal to or exceeding those of typical apex predators and (2) modify the spatiotemporal behaviour of other carnivores, including pumas and coyotes. We argue that the term ‘apex predator’ is highly context dependent and not a species‐wide status.

Giant panda twin rearing without assistance requires more interactions and less rest of the mother-A case study at Vienna Zoo.

PLoS ONE, 2018
The giant pandas' (Ailuropoda melanoleuca) reproductive strategy is unique among mammals. Yet there are characteristics of giant panda behaviour we do not fully understand.

Phaeohyphomycotic dermatitis in a giant panda (Ailuropoda melanoleuca) caused by Cladosporium cladosporioides. [PDF]

Med Mycol Case Rep, 2013
We report here a clinical case of phaeohyphomycosis in an 18-year-old male giant panda (Ailuropoda melanoleuca). Skin lesions on the giant panda disappeared following 2 months of treatment with ketoconazole. Three months after discontinuing the treatment, there was a clinical and mycological relapse.

Electroejaculation and semen analysis and freezing in the giant panda (Ailuropoda melanoleuca) [PDF]

Reproduction, 1983
Semen was collected by a standardized electroejaculation procedure from a giant panda on 4 occasions. Ejaculate volume, sperm count and % sperm motility were 2.3-3.6 ml, 62-562 x 10(6) spermatozoa/ml and 45-85%, respectively. The results, although limited to a single male, suggested a seasonal influence on ejaculate and gonadal parameters with improved
