A novel viral infection in a Captive Colony of pelagic red crabs (Pleuroncodes planipes) from California.

Captive, pelagic red crabs (Pleuroncodes planipes) had shortened lifespans and cutaneous black spots. Histologically, epidermal and mesenchymal cells had 3-5 µm diameter intranuclear inclusions, necrosis, vacuolation, and/or hyperplasia. The remaining organs were histologically unremarkable.

Polyglucosan storage disease in a black-capped parrot (Pionitesmelanocephalus).

Following an episode of sudden lethargy, an 18-month-old female black-capped parrot (Pionites melanocephalus) died while being examined. On gross examination, there was fluid within the coelom, hepatomegaly with yellow colouration and the heart appeared enlarged with pallor throughout the myocardium. On histological examination, cardiomyocytes were swollen with loss of cross striations and contained 6-12-μm diameter intrasarcoplasmic pale grey inclusions of storage material.

Amyloid-producing ameloblastoma of the maxilla in a 17-year-old cynomolgus macaque (Macacafascicularis).

Amyloid-producing ameloblastomas (APAs) are a histological variant of ameloblastoma in which the neoplastic odontogenic epithelial cells are associated with the production of amyloid. This jaw-associated entity has been only rarely described in animals and purportedly does not exist in humans. This report is the first description of an APA in a primate.

Uveal iridophoroma in a betta fish (Betta splendens).

Chromatophoromas are neoplasms arising from pigment cells in vertebrates. Iridophoromas are a type of chromatophoroma that are reported in several teleost species. There are multiple case reports of this diagnosis in betta fish (Betta splendens), but all previously reported cases originated from the skin.

A global database of soil seed bank richness, density, and abundance.

A soil seed bank is the collective name for viable seeds that are stored naturally in the soil. At the species or population level, the ability to form a seed bank represents a strategy for (re)colonization following a disturbance or other change in the local environmental conditions. At the community level, seed banks are thought to buffer local diversity during periods of environmental change and are often studied in relation to the potential for passive habitat restoration.
