Uniparental incubating birds must resolve the trade-off between self-maintenance and incubation. This balance manifests through diverse incubation behaviours that vary significantly among species and geographic regions. However, limited research has examined the variability of incubation behaviours across species and regions.

However, the differences in spatial variability and assembly mechanisms of various taiga forest soil microbial taxa remain poorly understood. Here, we assessed the spatial patterns of bacterial and fungal communities, their assembly processes, and the influencing factors in taiga forest ecosystems in Xinjiang, China.

For many birds, harsh weather in winter often imposes a strong selective effect on their survival, and only the individuals with certain phenotypes may survive. However, whether the selective effect on phenotype varies with winter weather conditions has been poorly investigated.

Flagship birds play a key role in raising conservation funds, increasing awareness of biodiversity conservation, and maintaining ecosystem services. This study selected flagship bird species in Lishui, Zhejiang Province, China, and assessed their conservation effectiveness and ability to serve as umbrella species.

Uncovering the dispersal pattern of a threatened species facilitates conservation efforts. Most species of Galliformes are forest-dwelling terrestrial birds with a weak dispersal ability and high conservation priorities.

However, the coevolutionary relationships between eye size and ecological factors, behaviours and brain size in birds remain poorly understood. Here, we investigate whether eye size evolution is associated with ecological factors (e.

However, the status of protected wildlife in PAs remains unclear. In this study, we conducted a national assessment of the status of protected wildlife and suggested an optimization plan to overcome these shortcomings.

However, the indirect impacts of changes in human activities are often easily overlooked. We conducted surveys of Reeves's Pheasant () and its sympatric species by camera traps in forest-type nature reserves in three different scenarios: pre-lockdown, lockdown and post-lockdown.

Previous studies have demonstrated the impact of livestock grazing and human presence on the habitat use of birds, whereas little is known about the effect of free-ranging livestock on bird behaviour. Reeves's Pheasant () is endemic to China and has been threatened by habitat loss and fragmentation, illegal logging, and human disturbance over the past 20 years.

Oil and its pollutants, which enter environment through natural oil seepage and many human activities, have considerable impacts on birds. We summarized the research advances in how oil pollutants influence birds and the cleaning technology of polluted birds and their habitats. The toxicity and destruction to feather structure are the major impacts of oil pollution on birds.

However, it remains unclear how the movement patterns of the Reeves's Pheasant () respond to human disturbance in human-dominated landscapes. We tracked the movement of 40 adult individual Reeves's Pheasants during the breeding season, and used the dynamic Brownian bridge motion model and kernel density estimation to analyze the diurnal movement patterns of Reeves's Pheasants and their response to human presence.

Difficulties involved in fieldwork at high elevations cause challenges in researching mechanisms facilitating species coexistence. Herein, we investigated Snow Partridge () and Tibetan Snowcock (), the only two endemic Galliformes on the QTP, to understand species coexistence patterns and determine how they live in sympatry for the first time.

Objective: Our goal was to investigate the function of all five vestibular end-organs pre- and post-cochlear implantation in children with LVAS and normal CT.
Methods: In this retrospective cohort study, 34 children (age 4-17 years) with bilateral profound sensorineural hearing loss (SNHL) undergoing unilateral CI were included.
Human infrastructure development drives habitat loss and fragmentation worldwide. In China, over the last 20 years, rapid infrastructure development impacted the habitats of endangered species. To facilitate conservation efforts, studies of how human infrastructure affects the distribution of Reeves's pheasant (), an endangered species by the International Union for Conservation of Nature (IUCN) and a nationally protected species in China, are critically needed.

Children with an enlarged vestibular aqueduct (EVA) need CI for severe or profound hearing loss, with excellent outcomes in hearing rehabilitation. However, vestibular function influenced by CI in children with EVA has not been clarified.

In altricial birds, where parents feed their offspring at the nest for a period of time, parent birds must balance the benefit from increased nest visits and the cost from increased nest predation resulting from their nest visits being detected by predators. Empirical evidence has shown a relationship between parental nest visits and nest predation risks, and parents have been found to be able to reduce the chance of being detected by predators by synchronizing their feeding visits while maintaining feeding rate unchanged.

However, landscape change and unreasonable zoning designations often render these protected areas inadequate. Therefore, regular evaluation of the efficacy of protected lands is critical for maintaining and improving management strategies.

Lateral bias in limb use, as a type of behavioral lateralization, occur in many species, but the reasons for the coexistence of left- and right-biased individuals in a population remain poorly understood. We examined the footedness of male yellow-bellied tits () when they used feet to clamp mealworms against a perch, and tested its association with other fitness-related behavioral traits (i.

Materials And Methods: In this study, we loaded tetracycline onto TiO nanotubes to demonstrate its antibacterial properties and biocompatibility. The two-layered anodic TiO nanotubes with a honeycomb-like porous structure were fabricated by using a two-step anodization, and they were loaded with tetracycline by using a simplified lyophilization method and vacuum drying.
Accurate individual identification is required to estimate survival rates in avian populations. For endangered species, non-invasive methods of obtaining individual identification, such as using molted feathers as a source of DNA for microsatellite markers, are preferred because of less disturbance, easy sample preparation and high efficiency. With the availability of many avian genomes, a few pipelines isolating genome-wide microsatellites have been published, but it is still a challenge to isolate microsatellites from the reference genome efficiently.
