Evolution of fast-growing piscivorous herring in the young Baltic Sea.

The circumstances under which species diversify to genetically distinct lineages is a fundamental question in biology. Atlantic herring (Clupea harengus) is an extremely abundant zooplanktivorous species that is subdivided into multiple ecotypes that differ regarding spawning time and genetic adaption to local environmental conditions such as temperature, salinity, and light conditions. Here we show using whole genome analysis that multiple populations of piscivorous (fish-eating) herring have evolved sympatrically after the colonization of the brackish Baltic Sea within the last 8000 years postglaciation.

Parasympathetic Dysfunction Prevails in GBA1-Associated Parkinson's Disease.

Background: The role played by sympathetic and parasympathetic autonomic branches in patients with Parkinson's disease carrying variants in the GBA1 gene (GBA-PD) is still elusive.

Objectives: To characterize cardiovascular autonomic function in GBA-PD and I-PD patients with early and mid-stage disease.

Methods: These assessments were performed: cardiovascular autonomic tests, analysis of heart rate and blood pressure variability, cardiac noradrenergic imaging.

Feline Panleukopenia Virus in a Marsican Brown Bear and Crested Porcupine, Italy, 2022-2023.

The virus species Protoparvovirus carnivoran 1 encompasses pathogens that infect both domestic and wild carnivores, including feline panleukopenia virus. We identified and characterized feline panleukopenia virus strains in a Marsican brown bear (Ursus arctos marsicanus) and a crested porcupine (Hystrix cristata) in Italy, extending the known host range of this virus.

Pathology-Based Animal Cancer Registry of Abruzzo and Molise Regions (Central Italy): A Ten-Year Retrospective Study (2014-2023).

Pets have a crucial role in cancer research. Specifically, dogs and cats share the same environment as their owners and thus may serve as sentinels of naturally occurring tumors that are linked to the exposure to environmental hazards. Quantitative comparison of tumor types may reveal unusual cancer frequencies, providing directions for research and generation of hypotheses of cancer causation in a specific area and identification of risk factors.

The Determination of the Prohibited Herbicide 4,6-Dinitro-Ortho-Cresol (DNOC) in Poisoned Domestic and Wild Animals in Italy.

This study reports the determination of DNOC in the baits and gastric contents of poisoned dogs and wild canids collected in the Abruzzo region between 2014 and 2022. A total of 663 samples of the baits and carcasses of domestic and wild animals were analyzed for the determination of DNOC through GC-MS. DNOC was found to be present in 58 cases from 663 analyzed samples, with 49 poison baits and nine gastric content samples from dogs and red foxes.
