The majority of flowering plants require animals for pollination, a critical ecosystem service in natural and agricultural systems. However, quantifying useful estimates of pollinator visitation rates can be nearly impossible when pollinator visitation is infrequent. We examined the utility of an indirect measure of pollinator visitation, namely pollen receipt by flowers, using the hummingbird-...

Open visitation has been highly recommended by critical care groups but is not prevalent in practice. Here we discuss the present study on current visitation practices in US ICUs and discuss several factors affecting open visitation. We conclude with suggestions on achieving more liberal visitation practices.

OBJECTIVE Visitation is a method for external peer review. The goal is to improve the quality of patient care by giving feedback on quality of competence and performance of a professional during a practice visit. Feedback is offered as recommendations for improvement. This study aims to evaluate the effects of visitation and to determine which factors are related to the effectiveness of visitat...

Children's psychological adjustment following parental separation or divorce is a function of the characteristics of the custodial parent, as well as the degree of postdivorce parental cooperation. Over time, custody has shifted from fathers to mothers and currently to joint arrangements. In this retrospective chart review of family court clinic records we examined predictors of custody and vis...

Planning the artificial pollination of agricultural crops requires knowledge of the floral biology and reproductive system of the crop in question. Many studies have shown that rapeseed (Brassica napus Linnaeus) is self-compatible and self-pollinated, but its productivity may be increased by insect visitation. In the present study, the floral biology and the response of productivity to insect v...

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 ...
