Life satisfaction and time-use among full-time and part-time working mothers in Brazil.

Background: Working part-time or full-time is a persistent dilemma for women, especially mothers, as they strive to manage their time across various roles. However, the existing literature remains unclear on whether part-time work contributes more to life satisfaction than full-time work.

Objective: This study aims to describe and compare time-use patterns in different occupational roles and levels of life satisfaction among 795 mothers in Brazil who are employed either part-time or full-time.

Female mate choice of male signals is unlikely to promote ecological adaptation in treehoppers (Hemiptera: Membracidae).

A key question in speciation research is how ecological and sexual divergence arise and interact. We tested the hypothesis that mate choice causes local adaptation and ecological divergence using the rationale that the performance~signal trait relationship should parallel the attractiveness~signal trait relationship. We used female fecundity as a measure of ecological performance.

In Vitro Culture and Phytochemical Analysis of Passiflora tenuifila Killip and Passiflora setacea DC (Passifloraceae).

We have developed reproducible micropropagation, callus culture, phytochemical, and antioxidant analysis protocols for the wild passion fruit species P. tenuifila, and P. setacea, native to the Brazilian endangered biomes Atlantic Forest, Cerrado, and Caatinga, by using seeds and explants from seedlings and adult plants.
