Anaplastic cutaneous plasmacytoma in a dog

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract Extramedullary cutaneous plasmacytoma is an uncommon tumour in dogs and rare in cats, often linked to chronic inflammation or prolonged antigenic stimulation. It typically affects middle‐aged to older dogs, involving the head, trunk, limbs and digits.

A test of the thermal melanism hypothesis in the wingless grass-hopper Phaulacridium vittatum

, 2013
Altitudinal clines in melanism are generally assumed to reflect the fitness benefits resulting from thermal differences between colour morphs, yet differences in thermal quality are not always discernible.

Paler within the city: Carotenoid‐based colouration covaries negatively with the proportion of impervious surface in great tit (Parus major) territories across Europe

Journal of Animal Ecology, Volume 95, Issue 11, Page 2200-2213, November 2026.
Across six European cities, great tits in more impervious territories had paler carotenoid‐based plumage, but not lower brightness or UV chroma. This suggests that urban habitat imperviousness is associated specifically with lower carotenoid pigment deposition, rather than broad changes in feather reflectance or structural quality.

Genetic Spectrum of Non‐PTPN11 Variants in Noonan Syndrome and Related RASopathies: Findings From a Russian Cohort

Clinical Genetics, Volume 110, Issue 5, Page 527-537, November 2026.
Noonan syndrome and related conditions are caused by variants in multiple genes. We analyzed 456 Russian patients using a 23‐gene panel and found disease‐causing variants in non‐PTPN11 genes in 85 cases. NF1, SOS1, BRAF, and SHOC2 explained half of these diagnoses.

Comparative venom analysis between melanistic and normally coloured phenotypes of the common adder (Vipera berus)

Royal Society Open Science
Snake venom is an ecologically relevant functional trait directly linked with a snake’s fitness and survival, facilitating predation and defence. Snake venom variation occurs at all taxonomic levels, but the study at the intraspecific level is still in ...

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Beyond Pigmentation: Dermoscopic Vascular Patterns Reveal Novel Risk and Protective Factors in Melasma

Journal of Cosmetic Dermatology, Volume 25, Issue 11, November 2026.
ABSTRACT Objective To investigate the correlation between the dermoscopic severity of telangiectasia and key pathophysiological features in melasma, and to identify the risk factors associated with vascular pattern severity. Methods In this cross‐sectional study, 137 female melasma patients were classified into four vascular types based on dermoscopic ...
