Summary: Habitat selection analysis provides insights into how animals perceive different habitats and how these perceptions change over time or in relation to availability. It can be used to develop strategies for habitat management and conservation goals. GPS relocations of marked animals are the main data used in this analysis.

Summary: This study evaluated the exposure risk of Northern Pintail waterfowl wintering in two wetland habitats in the Purulia district of West Bengal. The study found that exposure through food plants ingestion and food-associated sediment consumption were the main sources of heavy metal exposure for the waterfowl. At one of the sites, the total exposure dose of all four metals exceeded the tolerable daily intake, posing a threat to the wintering herbivorous waterfowl populations.

Summary: The contemporary human diet is high in saturated fatty acids compared to that of our Palaeolithic ancestors, and the ratio of n-6 to n-3 polyunsaturated fatty acids (PUFAs) has greatly increased. This lifestyle and unsuitable diet have contributed to the rise of civilization diseases and sudden deaths. A study on mallard ducks aimed to analyze the fatty acid composition of selected tissues in relation to the human diet, where they were obtained, and their sex. The results showed that mallards from the Siedlce hunting district had lower levels of saturated and monounsaturated fatty acids, and higher levels of polyunsaturated fatty acids, n-6 PUFAs, and n-3 PUFAs in their breast muscles, indicating a higher health-promoting value in the meat from this region.

Summary: The genome sequence of a Sobemovirus was identified in the feces of northern pintail in Xinjiang, China, through metagenomic sequencing. This virus has a linear RNA molecule and is closely related to SoMV-WA and ATCC PV-109 with a nucleotide identity of 86.7%. Phylogenetic analysis suggests that the virus belongs to the species Sowbane Mosaic Virus. This is the first report of SoMV in the feces of wild birds and in China, indicating a potential role of northern pintail in the transmission of SoMV.

Summary: Our study on Northern Pintails wintering in Southern Europe supports the 'wintering strategy hypothesis', showing that their body mass increases in midwinter and decreases in late winter, indicating an energy-minimizing migration strategy through adapting fat reserves and exploiting food stock along their migration route. This strategy allows them to allocate more energy and time for activities such as moulting and pairing.

Summary: A qualitative analysis of mallard ducks' tissues and organs revealed the potential hygienic and toxicological threats related to lead and cadmium concentrations. The study found that mallards have a measurable response to environmental pollution with lead and cadmium, making them potential bioindicators of contamination levels. The ban on lead pellets in Poland may help reduce lead contamination in mallards' tissues and organs.

Summary: The study found that concentrations of toxic elements in sheep reared in northern Spain were within the ranges determined in other monitoring studies worldwide. Toxic element residues, except for cadmium in offal, were below the maximum limits established by the EU, posing no risk for human consumption. Essential trace elements concentrations were generally within the adequate-safe range established for sheep, with copper being an exception that required careful regulation in sheep flocks in the region.

Summary: The study found that the concentrations of potentially harmful elements in edible tissues of trout fish in the Phander Valley were within the threshold limits set by FAO. Chronic risk assessment showed that zinc consumption in fish muscle posed the highest risk for juveniles, while cadmium consumption posed the lowest risk for adults. High HQ values for juveniles consuming cadmium in fish tissues exceeded the threshold limit, indicating a potential chronic risk.

Summary: Despite mRNA-based SARS-CoV-2 vaccines showing over 90% efficacy, breakthrough infections can still occur, especially with variants like B.1.427/B.1.429. Most post-vaccine SARS-CoV-2 cases happened before full immunity was expected, and the B.1.427/B.1.429 variant was not more prevalent in vaccinated cases compared to unvaccinated healthcare personnel.

Summary: This study reports four cases of accessory thoracic muscle variations in an ethnically diverse whole-body donation population in Northern California. The findings show that different presentations of accessory thoracic muscles are common and may have close associations with the axilla. These findings provide valuable insights into the clinical implications of accessory thoracic muscles.
