Do Native and Alien Species Differ in Their Ecological Strategies? A Test with Woody Plants in Tropical Rainforests on Réunion Island (Mascarene Archipelago, Indian Ocean).

Understanding the mechanisms of biological invasions (e.g., competitive exclusion) is a key conservation challenge, especially on islands.

[Caregivers faced with painful events, testimonials].

Whatever the profession of caregivers, their activity involves supporting patients and families who are suffering. Doctors and nurses, in particular, talk of the strong emotions which they feel but which they find difficult to express. Being aware of them is essential for being able to accept them and limit their consequences.

Longitudinal qualitative study describing family physicians' experiences with attempting to integrate physical activity prescriptions in their practice: 'It's not easy to change habits'.

Objective: Physical activity (PA) prescriptions provided by family physicians can promote PA participation among patients, but few physicians regularly write PA prescriptions. The objective of this study was to describe family physicians' experiences of trying to implement written PA prescriptions into their practice.

Design: Longitudinal qualitative study where participants were interviewed four times during a 12-month period.

Reproductive patterns, genetic diversity and inbreeding depression in two closely related Jumellea species with contrasting patterns of commonness and distribution.

Backgrounds And Aims: Theory predicts that the long-term persistence of plant populations exposed to size reduction can be threatened by a loss of genetic diversity and increased inbreeding. However, several life-history and ecological traits can influence the response to population size reduction. The reproductive patterns, levels of genetic diversity and magnitude of inbreeding depression of the rare and fragmented Jumellea fragrans and of its widespread congener J.

The cardiovascular effect of the uremic solute indole-3 acetic acid.

In CKD, uremic solutes may induce endothelial dysfunction, inflammation, and oxidative stress, leading to increased cardiovascular risk. We investigated whether the uremic solute indole-3 acetic acid (IAA) predicts clinical outcomes in patients with CKD and has prooxidant and proinflammatory effects. We studied 120 patients with CKD.
