Chimpanzees possess a large number of behavioral and cultural traits among nonhuman species. The "disturbance hypothesis" predicts that human impact depletes resources and disrupts social learning processes necessary for behavioral and cultural transmission. We used a dataset of 144 chimpanzee communities, with information on 31 behaviors, to show that chimpanzees inhabiting areas with high human impact have a mean probability of occurrence reduced by 88%, across all behaviors, compared to low-impact areas. This behavioral diversity loss was evident irrespective of the grouping or categorization of behaviors. Therefore, human impact may not only be associated with the loss of populations and genetic diversity, but also affects how animals behave. Our results support the view that "culturally significant units" should be integrated into wildlife conservation.

In this study, surface water, sediment, and fish samples were collected from five regions along the northern coasts of Cyprus during both summer and winter seasons to assess their microplastic contamination levels. In surface waters, the highest microplastic concentrations per square meter were recorded in the following order: Karpaz (North) (0.16 MP/m), Güzelyurt (0.

In agriculture, biosecurity, and human health, the rapid and accurate detection of pathogens and pests is crucial. Our study investigates the sensitivity and practicality of six guide RNA (gRNA) production methods for use in Nanopore Cas9-targeted sequencing (nCATS), focusing on their implications for multiplexed pathogen and pest detection. Each production method generated a library of eight gRNAs capable of excising ~ 1.

Compared to sun-exposed melanomas, acral melanomas are genetically diverse and occur in areas with low sun exposure and high mechanical loads. During metastatic growth, melanomas invade from the epidermis to the dermis layers through dense tumor stroma and are exposed to fibrillar collagen architectures and mechanical stresses. However, the role of these signals during acral melanoma pathogenesis is not well understood.

Epigenetic processes, such as DNA methylation, show potential as biological markers and mechanisms underlying gene-environment interplay in the prediction of mental health and other brain-based phenotypes. However, little is known about how peripheral epigenetic patterns relate to individual differences in the brain itself. An increasingly popular approach to address this is by combining epigenetic and neuroimaging data; yet, research in this area is almost entirely comprised of cross-sectional studies in adults.

Purpose: The aim of this study was to evaluate the radiological-functional outcomes and rotator cuff (RC) status following humeral intramedullary nailing (IMN), comparing the anterolateral standard approach (group 1) and the percutaneous antero-acromial approach (group 2).
Methods: This observational prospective monocentric study was conducted from August 2021 to March 2023. Inclusion criteria included: two-parts proximal (surgical neck) and diaphyseal Humeral fractures treated with IMN; 12-month follow-up; age between 18 and 85 years; good performance status (excluding neurologic deficits or mental disorders).
