Obsessive-compulsive symptoms in anxiety and depressive disorders: Influence of recent and/or traumatic life events.

Introduction: A high prevalence of obsessive-compulsive symptoms (OCSs) in anxiety-depressive disorders ranging from 30 to 67% has been described.

Objective: This study aims to assess the presence and persistence of OCSs in an outpatient sample of subjects with anxiety and depressive disorders, as well as its relationship with recent life events (RLEs) and/or traumatic experiences (TEs).

Method: We conducted a prospective, observational, analytical study of 200 subjects with DSM-5 diagnoses of anxiety and/or depression.

Linkages among life-history components through time: Carryover effects on the demography of a short-lived polycarpic plant.

Premise Of The Study: Current reproduction in polycarpic plants may be affected by a wide variety of factors, including carryover or "historical" effects derived from environments experienced early in life and from previous investments in organ preformation or other life functions, such as growth or reproduction. Historical effects as determinants of plant reproductive success in a specific season have received considerably less attention than events during the current reproductive episode, especially for short-lived plants. •

Methods: We used structural equation modeling to assess direct and indirect relations between past reproduction and both subsequent reproduction and growth in Helianthemum squamatum, a short-lived polycarpic plant.

Survival costs of reproduction in a short-lived perennial plant: Live hard, die young.

According to life-history theory, reproductive investments involve costs in terms of growth, future fecundity, and/or survival. However, studies to date have often failed to detect costs of reproduction, with survival costs among the less documented. We investigated the cost of reproduction in Helianthemum squamatum (Cistaceae), a short-lived perennial of semiarid Mediterranean environments.

Environmental scales on the reproduction of a gypsophyte: a hierarchical approach.

Background And Aims: Environmental variability at several scales can determine plant reproductive success. The main goal of this work was to model the reproductive flexibility of a semi-arid specialist considering different scales of environmental variability.

Methods: A 2-year field study was performed on the determinants of the female reproductive success of Helianthemum squamatum, an Iberian gypsophyte, considering two scales of environmental variability: differences between two contrasting slope aspects; and, on individual scale, the neighbouring microenvironment.
