Stable Isotopes Analysis of Black Lion Tamarins Reveals Increasing Arthropod Consumption When Fruit Productivity Decreases in Forest Fragments.

Given the cryptic and elusive nature of prey consumption, quantifying its contribution to the diet of free-ranging primates using behavioral methods is challenging. In this context, the use of carbon and nitrogen-stable isotopes represents a promising alternative approach. Here, we used stable isotope analysis to estimate the proportion of arthropods and fruits in the diet of black lion tamarins (Leontopithecus chrysopygus), an endangered primate endemic to the Brazilian Atlantic Forest.

Food web collapse and regime shift following goldfish introduction in permanent ponds.

In a global context of invasive alien species (IAS), native predators are often eradicated by functionally different IAS, which may induce complex cascading consequences on ecosystem functioning because of the key role predators play in structuring communities and stabilizing food webs. In permanent ponds, the most abundant freshwater systems on Earth, global human-mediated introductions of alien omnivores such as the pet trade goldfish are driving broad-scale patterns of native predators' exclusion, but cascading consequences on food web structure and functioning are critically understudied. We compared food webs of naturally fishless ponds versus ponds where dominant native predators (newts) had been extirpated by invasive goldfish within the last decade.

Impact of text difficulty and visual emphasis on pediatric neuropsychological evaluation reports: The parent's perspective.

Despite varying opinions, little research has examined how to best write pediatric neuropsychology reports. This study gathered input from 230 parents on how text difficulty (reading level) and visual emphasis (bullets, underline, italics) affect report readability and utility. We focused on the most-read report section: summary/impressions.

Perceptions of antibiotic resistance among hospital healthcare professionals in high-income countries: A systematic review of causes, consequences, and solutions.

Objective: Antibiotic resistance (ABR) is a major threat to public health. Hospital healthcare professionals are important stakeholders in curbing ABR. To be able to encourage healthcare professionals to act against ABR, information on their perceptions is needed.
