Seagrasses live in highly variable light environments and adjust to these variations by expressing acclimatory responses at different plant organizational levels (meadow, shoot, leaf and chloroplast level). Yet, comparative studies, to identify species' strategies, and integration of the relative importance of photoacclimatory adjustments at different levels are still missing. The variation in photoacclimatory responses at the chloroplast and leaf level were studied along individual leaves of Cymodocea nodosa, Zostera marina and Z.

Nevertheless, recent studies show evidence that Myrtaceae from different tropical, subtropical and neotropical ecosystems can also prompt the formation of ectomycorrhizae, indicating that this species' ectomycorrhizal status should be further explored. Because of this, this research effort studied the in vitro interaction between the Red Araza and two ectomycorrhizal fungi isolates, belonging to the Pisolithus microcarpus (D17) and Scleroderma citrinum (UFSC-Sc133) species.

- Coastal areas are experiencing increased variability in seawater pH due to ocean acidification and local stressors, which threatens marine organisms, but seagrass like Halodule wrightii may have adaptive traits.
- In a 30-day mesocosm study, different pH levels were simulated to assess the impact of elevated CO2 on seagrass physiology and anatomy, revealing that only the lowest pH conditions caused significant reductions in performance.
- The study concludes that the interactions between ocean acidification and environmental factors, such as light and nutrients, should be prioritized in research to better understand the resilience of marine plants like seagrass.
Objective: To determine the prevalence of dysmenorrhea, limitations in daily living and health care use due to menstrual pain.
Material And Methods: Observational transversal study of 274 adolescents and young adults (age ≤ 26) who had menstruated in the six months prior to the study, assisted at a Primary Health Care Center. Data were obtained by a 24-item anonymous questionnaire, which included questions about socio-demographic variables, menstrual cycle, presence, duration, severity, treatment and limitations of dysmenorrhea.
Purpose: To assess physical and psychological morbidity, sexual functioning and social and relationship satisfaction among women treated with pelvic radiotherapy.
Methods: Observational (case-control) study of 199 women: 98 submitted to pelvic radiotherapy for the treatment of uterine, rectal or anal cancers and 101 without a personal history of cancer and similar socio-demographic variables. These completed a socio-demographic and clinical questionnaire, and validated measures of psychological health (DASS: Lovibond and Lovibond in Behav Res Ther 33:353-343, 1995), sexual function (FSFI: Rosen et al.
