State parks are typically established to preserve natural or native habitats for wildlife while simultaneously providing recreational experiences for humans. However, because of their proximity to urban centers, the level of human visitation associated with state parks may be highly variable. Little information has been published regarding the eff ect of human visitation levels on wildlife esca...
Low pollinator visitation in harsh environments may lead to pollen limitation which can threaten population persistence. Consequently, avoidance of pollen limitation is expected in outcrossing species subjected to habitually low pollinator service. The elevational decline in visitation rates on many high mountains provides an outstanding opportunity for addressing this question. According to a ...
This investigation tested the incremental utility of cognitive retraining as a component within a program designed to prevent child maltreatment. High-risk families (N = 96) were randomly assigned to a control condition, home visitation modeled after the Healthy Start program (unenhanced home visitation), or home visitation that included a cognitive component (enhanced home visitation). Mothers...
Ecological and temporal factors can influence animal foraging patterns and may obscure our understanding of how native and exotic species interact. To understand how such factors affect foraging, the visitation of native and exotic bees and wasps was observed at nectar feeders within Mexican agroforestry systems, while documenting (1) vegetation management (low-shade vs. high-shade coffee), (2)...
A B S T R A C T Previous studies have shown that African Americans have less favorable impressions about wildlands and recreate on wildland areas less frequently than do whites. However, most of these investigations have been conducted on non-rural populations. Rural perceptions of wildlands and visitation to such areas have received relatively little attention. In this exploratory study, we pr...
background: visitation of patients admitted at intensive care units (icus) is a controversial issue in the field of health care. it is commonly believed that the presence of family members might bring about physiological changes, such as tachycardia and hypertension, in icu patients. aim: this study aimed to evaluate the effects of scheduled visitation on the physiological indices of conscious ...
The topic of critical care visitation has been researched and discussed over the past 25 years and still remains controversial. There still remain many concerns over the benefits of open or flexible visitation. A review of some research conducted in the past several years, perceived barriers to open visitation, and the benefits will be presented in this article.
Successful communication is critical to the fitness of individuals and maintenance of populations, but less is known regarding the social contexts and reactions to scent marking by other individuals in solitary carnivores, including pumas. We evaluated the responses of resident male pumas to visitation and scent marking by potential competitors (other male pumas) and potential mates (female pum...
OBJECTIVE This study aimed to determine which visitation policy was the most predominant in Brazilian intensive care units and what amenities were provided to visitors. METHODS Eight hundred invitations were sent to the e-mail addresses of intensivist physicians and nurses who were listed in the research groups of the Brazilian Association of Intensive Care Network and the Brazilian Research ...
The diversity and abundance of wild insect pollinators have declined in many agricultural landscapes. Whether such declines reduce crop yields, or are mitigated by managed pollinators such as honey bees, is unclear. We found universally positive associations of fruit set with flower visitation by wild insects in 41 crop systems worldwide. In contrast, fruit set increased significantly with flow...
