Manure odor profiling for flock-level monitoring on commercial layer pullet farms: Vaccination events as a model stressor.

Continuous, non-invasive, and objective methods to detect flock-level responses to stressors, including intestinal health deviations, are currently lacking in poultry. This proof of principle study investigated the potential of manure odor profiling in monitoring stress responses in Lohmann Brown Classic, Lohmann LSL Classic and Lohmann LSL Lite layer pullets. Stressors were represented by a Salmonella vaccination given to the pullets at wk 3 of age (Dataset 1 and Dataset 2) and wk 16 of age (Dataset 4) and a viral/bacterial vaccine cocktail given at wk 12 of age (Dataset 3).

Late Pleistocene onset of mutualistic human/canid ( spp.) relationships in subarctic Alaska.

Large canids (wolves, dogs, and coyote) and people form a close relationship in northern (subarctic and arctic) socioecological systems. Here, we document the antiquity of this bond and the multiple ways it manifested in interior Alaska, a region key to understanding the peopling of the Americas and early northern lifeways. We compile original and existing genomic, isotopic, and osteological canid data from archaeological, paleontological, and modern sites.

isolates contain frequent heterozygous structural variants and transposable elements within genes and centromeres.

The human fungal pathogen poses a significant burden on global health, causing high rates of mortality and antifungal drug resistance. is a heterozygous diploid organism that reproduces asexually. Structural variants (SVs) are an important source of genomic rearrangement, particularly in species that lack sexual recombination.

Key considerations when developing academic writing support for nursing and midwifery doctoral students: A scoping review.

Background And Aim: Academic writing is essential to achieve success for doctoral students and is often linked to their academic identity, which could provoke negative emotions leading to the risk of burnout and dropping out of their studies. Although academic writing is a substantial part of doctoral students' learning journey, there are no existing recommendations to guide the provision of effective support addressing nursing and midwifery doctoral students' needs in academic writing. This review aims to identify the key considerations that could facilitate education facilities and educators to provide effective support for academic writing among nursing and midwifery doctoral students, fostering a supportive environment for guidance and development.
