OBJECTIVE This study explored whether parents treated in public mental health settings perceived that they might lose child custody or visitation if they were not adherent to treatment. METHODS Interview data were gathered from 1,011 adult outpatients from five community mental health centers located in five states in different U.S. regions. RESULTS Among parents with children younger than ...

High rates of incarceration in the United States have motivated a broad examination of the effects of parental incarceration on child well-being. Although a growing literature documents challenges facing the children of incarcerated men, most incarcerated fathers lived apart from their children before their arrest, raising questions of whether they were sufficiently involved with their families...

Foraging pollinators can be expected to choose patches with high densities of floral resources. As a result, plants in flower-dense patches may receive higher visitation rates and pollination, hence, the pollination of one plant may be facilitated by the presence of neighbour plants. Facilitation of pollination has been predicted by theoretical models and demonstrated in some empirical studies,...

Mutualistic relationships between plants and their pollinators have played a major role in the evolution of biodiversity. While the vulnerability of these relationships to environmental change is a major concern, studies often lack a framework for predicting impacts from emerging threats (e.g. biological invasions). The objective of this study was to determine the reliance of Platanthera ciliar...

The authors assessed the effectiveness of a home visitation program in enhancing the early parenting history of infants born at medical risk--a population that is at risk for mistreatment. A randomized clinical trial design was used to compare the effects of a cognitively based extension of the Healthy Start home visitation program (HV+) with a visitation condition that did not include this com...

Plant responses induced by herbivore damage can provide fitness benefits, but can also have important costs due to altered interactions with mutualist pollinators. We examined the effects of plant responses to herbivory in a hummingbird-pollinated distylous shrub, Palicourea angustifolia. Through a series of field experiments we investigated whether damage from foliar herbivores leads to a redu...

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...

1. Long-term monitoring requires repeated visits to a study site, greatly increasing the potential for cumulative visitation effects. For ecological studies in general, and for monitoring in particular, data must be evaluated for confounding artefacts from researcher presence. We compared aquatic communities at long-term sampling plots (nine sites, each with three plots, studied continuously fr...
