AI Article Synopsis
- The study investigates how hunger influences puma behavior in areas where urban development meets wildland, particularly their risk avoidance of residential spaces.
- Well-fed pumas tend to avoid residential patches, even though these areas have more prey, whereas hungry pumas are more likely to venture into these areas despite the risks.
- The findings highlight the potential for increased puma-human conflicts as the animals' hunger drives them into closer proximity with human populations.
Article Abstract
In Focus: Blecha, K. A., Boone, R. B., & Alldredge, M. W. (2018). Hunger mediates apex predator's risk avoidance response in wildland-urban interface. Journal of Animal Ecology, 87, 609-622. https://doi.org/10.1111/1365-2656.12801 Puma (Puma concolor), an apex predator, can live at the edge of cities where pockets of low-density human dwellings form residential patches in the wildland-urban interface. Blecha, Boone, and Alldredge () tracked puma via global positioning system (GPS) telemetry collars to determine when and where they hunted and made kills. Well-fed puma (1-2 days between kills) strongly avoided residential patches despite these areas having higher mule deer (Odocoileus hemionus) densities and higher kill success for puma. However, the strong avoidance of residential patches completely disappeared as puma became hungrier (4-10 days since last kill) making it more likely that hungry individuals hunted in residential areas and ultimately increasing the likelihood of puma-human conflict.

Although wild boar invasion is a common human-wildlife conflict worldwide, it is difficult to solve. Understanding the characteristics of wild boar invasion into farmland, accurately predicting the areas where wild boar invasions will occur, and implementing effective prevention and control measures are key to effectively alleviating conflicts between humans and wild boars. From 2021 to 2023, we conducted field surveys and experimentally determined the effectiveness of prevention and control measures in the Huanan and Tonghe Counties in order to explore the landscape and farmland factors affecting wild boar invasion, as well as to evaluate the effectiveness of different combinations of prevention and control measures.

The influences of landscape pattern on water quality are dependent on spatial-temporal scales. However, the effects of landscape composition, landscape configuration, and landscape slope metrics on seasonal water quality at different spatial scales remain unclear. Based on the total nitrogen, total phosphorus, nitrate-N, and ammonium-N data from 26 sampling sites in the Qingshan Lake watershed, this study coupled landscape pattern analysis, redundancy analysis, and partial redundancy analysis to quantify the spatiotemporal scale effects of landscape pattern on riverine nitrogen （N） and phosphorus （P） concentrations.

Increased temperatures associated with urbanization (the "urban heat island" effect) have been shown to impact a wide range of traits across diverse taxa. At the same time, climatic conditions vary at fine spatial scales within habitats due to factors including shade from shrubs, trees, and built structures. Patches of shade may function as microclimate refugia that allow species to occur in habitats where high temperatures and/or exposure to ultraviolet radiation would otherwise be prohibitive.

Cause-specific estimates of mortality and the subsequent effects on life expectancy worldwide are valuable metrics to gauge progress in reducing mortality rates. These estimates are particularly important following large-scale mortality spikes, such as the COVID-19 pandemic.

Background: Few studies focus on the associations of green space composition and configuration with children's allergic rhinitis (AR).
Methods: A multi-center population-based cross-sectional study was performed in 7 cities in mainland of China between 2019 and 2020, recruiting 36,867 preschool children. Information on the current AR symptoms and demographics were collected by questionnaire.
