Summary: Mycoplasma infections have been found in various species of waterfowl, with Mycoplasma anserisalpingitidis being the most frequently detected species. Wild geese may serve as a reservoir and vector for different Mycoplasma spp., leading to significant economic losses in the domestic goose industry.

Summary: Combining new neuroscientific techniques with reductive approaches that consider central brain components in time and space has generated significant progress, allowing researchers to move from description and explanation to prediction and control. This progress promises to improve human health and well-being.

Summary: The ecological-constraints model suggests that larger group size in animals is associated with higher travel costs and reduced nutritional intake due to within-group feeding competition. However, this model may not apply to folivorous animals that feed on more abundant and evenly distributed food. This study focuses on the seasonal frugivorous diet of western gorillas to investigate the applicability of the ecological-constraints model in the largest primate species.

Summary: The study found that emperor geese are arriving at wintering areas earlier and staying longer than in the past. More emperor geese are now choosing to winter closer to breeding areas in western Alaska, likely due to increasing habitat availability from shifting environmental conditions. Additionally, fewer emperor geese are using the core area of their wintering range, indicating decreased habitat quality or a decrease in migration distance via alternative locations. The results highlight a rapid response to habitat change likely due to warming temperatures and reduced ice cover, underscoring the importance of understanding complex interactions among migration distance, the environment, and habitat selection.

Summary: The management interventions of culling did not significantly increase individual social connectivity in a resident Canada goose population. Instead, the surviving geese responded by strengthening existing social relationships and forming new, compensatory relationships with local birds. However, the establishment of new associations was limited and occurred locally.

Summary: This study focuses on the effects of particle size distribution and nano-additives on the flowability and fluidization quality of Group C and Group A powders. The results indicate that nano-modulation can improve the flowability and gas-solid contact of Group C particles, while a narrower particle size distribution contributes to better flowability.

Summary: The AB blood group system has been found in both wild felids and domestic cats, with type A blood being the most common. There is variation between species, but not within species, and no evidence of geographical variation has been found. Further studies are needed to determine the clinical relevance of AB blood group in wild felids.

Summary: This study investigated the potential of using body size traits in the selection and breeding of high-yielding Wulong geese. The results showed that neck circumference, pubic spacing, neck length, and abdominal circumference are important indicators for selecting high-yielding geese.

Summary: The prevalence of Riemerella anatipestifer (RA) infection in different types of commercial poultry in Poland was evaluated, and the potential role of wild geese as vectors of this pathogen was verified. Results showed that the highest RA prevalence was found in duck (35.7%) and goose (30.0%) flocks, while the lowest was found in turkeys (3.2%). Most tested wild geese (94.7%) were RA positive. Phylogenetic analysis revealed low genetic diversity among the sequences analyzed, suggesting that RA isolates from commercial poultry circulate in wild bird populations but are not transmitted back to poultry.

Summary: Classifying elements of the Brauer group of a variety X over a p-adic field by p-adic accuracy gives a filtration on Br X. This filtration is related to that defined by Kato's Swan conductor. The refined Swan conductor controls the variation of evaluation maps on p-adic discs, providing a geometric characterization of the refined Swan conductor. We apply this to rational points on varieties over number fields, including the failure of weak approximation for varieties admitting a non-zero global 2-form.

Summary: Land use changes have had a positive impact on the wintering population of bar-headed geese, with abandoned croplands reducing human disturbance and larger water and grassland areas providing more foraging and resting opportunities for the geese.

Summary: Many Arctic-breeding animals are at risk from local extirpation due to habitat constriction and alterations in phenology caused by rapid global warming. Migratory species are also facing increasing anthropogenic pressures along their migration routes. These species can only survive by adjusting their migration, breeding timing, and range.

Summary: In the present Anthropocene, wild animals are globally affected by human activity. New Year fireworks have negative effects on wild birds, causing them to fly longer distances, higher altitudes, and more frequently change roosting sites, even when fireworks activity is reduced.

Summary: Researchers recognize the importance of cost-effective, non-invasive techniques for in-situ morphological measurements. We successfully measured the body sizes of wild Painted Storks in two different regions using a non-invasive digital method. Our study demonstrates the effectiveness of this method in classifying and predicting species characteristics and identifying eco-geographic patterns.
