The purpose of this study was to determine the morphometrical characteristics of the larval hooks of Echinococcus granulosus in Turkey. The number of rostellar hooks (NH) and the total length of long blades, length of the blade of the long hooks, the total length of small blades and the length of the blade of the small hooks were measured in sheep and cattle isolates. The principal component and discriminant function analyses were used to analyze the data. Rostellar structure of protoscoleces was very similar in the sheep and cattle samples. According to the correlation matrix, the hook number and the hook length was negatively correlated. However, the correlation between the hook lengths was positive. It was found that the morphometric characteristics of the samples from the sheep and cattle closely resembled each other.

Antibiotics are extensively used in livestock production to prevent and treat diseases, but their environmental impact through contamination of rivers and groundwater is a growing concern. The specific antibiotics involved, their sources, and their geographic distribution remain inadequately documented, hindering effective mitigation strategies for river and groundwater pollution control caused by livestock production. Here we develope the spatially explicit MARINA-Antibiotics (China-1.

Nonadditive genetic effects pose significant challenges to traditional genomic selection methods for quantitative traits. Machine learning approaches, particularly kernel-based methods, offer promising solutions to overcome these limitations. In this study, we developed a novel machine learning method, KPRR, which integrated a polynomial kernel into ridge regression to effectively capture nonadditive genetic effects.

Arbuscular mycorrhizal fungi (AMF) form extensive symbiotic relationships with plants, which are critical for plant-driven biogeochemical cycles and ecosystem functions. Grazing and mowing, which are common grassland utilization patterns globally, significantly alter plant community characteristics as well as soil nutrients and structure, thereby potentially influencing AMF communities. However, the effects of these grassland managements on AMF community structure and ecological processes remain unclear.
