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...
Studies of zoochorous seed dispersal systems often consider crop size, yet seldom consider the kinds and amounts of fruits surrounding parent plants (the fruit neighborhood) when attempting to explain among-plant variation in fruit removal. We studied avian frugivory at 24 Schefflera morototoni trees from February to May 1998 in central Puerto Rico. The number of fruits removed by avian seed di...
For nearly two decades, home visitation has been promoted as a promising strategy to prevent child maltreatment, but reviews of the literature on home visiting programs have been mixed. This article examines how home visitation for the prevention of child maltreatment has evolved during the past 20 years. It reviews several home visitation programs focused on preventing child maltreatment and h...
Mate selection influences individual fitness, is often based on complex cues and behaviours, and can be difficult to study in solitary species including carnivores. We used motion-triggered cameras at 29 community scrapes (i.e. scent marking locations used by multiple individuals) and home range data from 39 GPS-collared pumas (Puma concolor) to assess the relevance of communication behaviours ...
1. Pollinator declines caused by forage habitat loss threaten insect pollination services. Pollinating insects depend on adequate floral resources, and their ability to track these resources. Variability of these resources and the effect on insect foraging choice is poorly understood. 2. We record patterns of visitation to six wildflower species and test the hypotheses that: pollinators prefere...
Most rewardless orchids engage in generalized food-deception, exhibiting floral traits typical of rewarding species and exploiting the instinctive foraging of pollinators. Generalized food-deceptive (GFD) orchids compete poorly with rewarding species for pollinator services, which may be overcome by flowering early in the growing season when relatively more pollinators are naive and fewer compe...
Intensive care medicine is a complex process with important repercussions for patients’ families. A systematic approach that incorporates family care is one of the pillars of humanized care. Beyond human aspects, this philosophy is associated with pragmatic outcomes and better communication and family satisfaction with care.(1,2) Some authors have shown how family satisfaction with care provide...
INTRODUCTION Prior reports suggest that restrictive ICU visitation policies can negatively impact patients and their loved ones. However, visitation practices in US ICUs, and the hospital factors associated with them, are not well described. METHODS A telephone survey was made of ICUs, stratified by US region and hospital type (community, federal, or university), between 2008 and 2009. Hospit...
