Animal telemetry is a powerful tool for observing marine animals and the physical environments that they inhabit, from coastal continental shelf ecosystems to polar seas open oceans. Satellite-linked biologgers networks of acoustic receivers allow be reliably monitored over scales tens meters thousands kilometres, giving insight into their habitat use, home range size, phenology migratory patterns biotic abiotic factors drive distributions. Furthermore, environmental variables can collected...
Ocean sunfish (Mola mola) were believed to be inactive jellyfish feeders because they are often observed lying motionless at the sea surface. Recent tracking studies revealed that actually deep divers, but there has been no evidence of foraging in water. Furthermore, surfacing behaviour ocean was thought related behavioural thermoregulation, record body temperature. Evidence feeding water obtained using a combination an animal-borne accelerometer and camera with light source. Siphonophores...
Self-organization of moving objects in hydrodynamic environments has recently attracted considerable attention connection to natural phenomena and living systems. However, the underlying physical mechanism is much less clear due intrinsically nonequilibrium nature, compared with self-organization thermal Hydrodynamic interactions are believed play a crucial role such phenomena. To elucidate fundamental nature many-body at finite Reynolds number, here we study system co-rotating hard disks...
Significance Monitoring ocean surface winds is essential for understanding and atmosphere interactions weather forecasts. However, wind measured by satellite scatterometers buoys are spatially temporally coarse, particularly in coastal areas. We deployed small global positioning system units on soaring seabirds to record their tracks. Seabirds were accelerated tail or slowed down head during flight, so flight speed changed relation direction. Taking advantage of these changes speed, we...
Bovine coronavirus (BCoV) is zoonotically transmissible among species, since BCoV-like viruses have been detected in wild ruminants and humans. BCoV causing enteric respiratory disease widespread cattle farms worldwide; however, limited information available regarding the molecular characterization of because its large genome size, despite significant economic impact. This study aimed to better understand genomic evolutionary dynamics via comparative sequence phylogenetic analyses through...
We experimentally demonstrate the observation of a frequency-shift dynamics at temporal boundary in terahertz (THz) region relying on scheme that controls structural dispersion metal-semiconductor waveguide. Ultrafast structural-dispersion switching is achieved within subpicosecond timescale by illuminating waveguide surface with an optical pump pulse during propagation THz Owing to relatively high conversion efficiency, up 23%, under condition frequency shift sufficiently larger than...

We documented the fluctuation of daily time budgets in Japanese black bears (Ursus thibetanus japonicus) throughout year using continuous day-to-day data from activity sensors integrated into global positioning system collars, during 2003–2009. evaluated influence availability food resources on active conjunction with differences sex and reproductive status females (with or without offspring). The fluctuated nonlinearly year. There were 3 turning points at which level clearly changed...
Ants are an important food resource for most of bear species. During the summer, Japanese black bears (Ursus thibetanus japonicus) use grasslands in ∼60 km2 Ashio area as ant feeding site. We studied levels myrmecophagy using GPS locations and activity sensor information along with direct observations 2 during 2004 2005. measured species composition, biomass, nutrient contents ants estimated through scat analysis. Both number biomass were higher than adjacent forest areas. recorded 15...
Bovine respiratory diseases (BRD) are associated with various predisposing factors, such as physical and physiological stress bacterial viral pathogens. These stressors viruses suppress immune defenses, leading to growth in the upper tract invasion of pathogens into lower tract. Therefore, continuous monitoring causative would contribute early detection BRD. Nasal swabs sera from 63 clinically healthy calves were continuously collected seven farms Iwate prefecture 2019 2021. We attempted...
The Japanese black bear (Ursus thibetanus japonicus) is a forest-dwelling species and can be very difficult to observe directly in most of its habitats. Therefore, as research tool evaluate activity patterns time budgets, we fitted GPS radiocollars with sensors on 4 bears, 2 males females, during 2003–06 the Ashio Mountains, which have open Through comparison observations from video camera sensor values, categorized activities either resting (inactive) or feeding short distance movements...
We examined food habits and home-range elevations of Japanese black bears (Ursus thibetanus japonicus) in relation to Fagaceae mast production Toyama Prefecture. Nine (four males five females) fitted with GPS collars were tracked for various periods from July December 2005–2007. investigated the each bear using traces found at GPS-fix locations. Bears selectively fed on Fagus crenata when F. Quercus crispula was abundant consumed Q. serrata scarce. When both scarce, multiple alternatives,...

Abstract Breakfast skipping has become an increasing trend in the modern lifestyle and may play a role obesity type 2 diabetes. In our previous studies healthy young individuals, single incident of breakfast increased overall 24-h blood glucose elevated postprandial glycaemic response after lunch; however, it was difficult to determine whether this due omission or extra energy (i.e. lunch plus contents). The present study aimed assess measure their hormone levels when individuals had...
Breeding success and survival in colonial seabirds are influenced by nest location, physical surroundings, external disturbances. Nest location may also directly or indirectly affect individual foraging behavior physiological conditions, shaping reproductive survival. Despite these influences, few studies have integrated the analysis of behavior, status. In this study, we analyzed 20 black-tailed gulls (Larus crassirostris) nesting center a colony within protected area (Central Group, CG)...
Understanding the relationship between behavior and physiological state, as well species differences in responses, is key to identifying behavioral adaptations necessary for wild animals avoid deterioration, thereby enhancing their survival fitness. A commonly used measure of condition oxidative stress, which results from an imbalance damage—often exacerbated by respiration during exercise indicative physical harm—and antioxidant capacity, reflects organism’s ability recover such damage....
