Comparative analysis reveals assortative mate preferences in darters independent of sympatry and sex
No full textA preference for mating with conspecifics over heterospecifics is fundamental to the maintenance of species diversity in sexually reproducing organisms. This type of positive assortative mating results in sexual isolation, a reduction in gene flow between species due to differences in mate choice. Sexual isolation is often stronger between closely related sympatric species as compared to allopatric species, because of processes such as reinforcement. In animals, this pattern has been demonstrated across the genus Drosophila, however, most empirical evidence for stronger species-level assortative mating in sympatry comes from studies of two or only a few species. In addition, traditional theories of sexual selection suggest that because reproduction is more costly to females, they should be the choosier sex. This prediction was supported in Drosophila, but it remains unclear whether this is a general trend in other taxa. To infer general patterns requires broad comparative analyses. We therefore compared mate preferences in sympatric and allopatric species of darters (genus Etheostoma). We performed a meta-analysis of 16 studies, encompassing 21 species. As expected, we found stronger preferences for conspecifics over heterospecifics across studies and species. Contrary to studies in Drosophila, however, the strength of preference for conspecifics was similar for allopatric and sympatric species pairs, as well as for males and females. We offer several variables to further explore (e.g. paternal care, degree of dimorphism, experimental factors), which could bring a more complete view of what modulates the strength of preference for conspecifics in the genus Etheostoma and help to understand better our present lack of evidence for an effect of geography and sex

No full textWe developed an open-source, computerized cognitive control test battery, consisting of 9 experimental tasks that can be used for young adults, but (with some modifications) also for children and older adults. These tasks index three cognitive control functions, namely Shifting, Updating and Inhibition, in line with Miyake et al. (2000)

Planejamento Financeiro e o Desenvolvimento Empresarial das Paróquias Urbanas e Rurais da Zona 5 no Equador
No full textLas empresas ubicadas en parroquias urbanas y rurales de la Zona 5 del Ecuador enfrentan limitaciones asociadas a una débil cultura financiera y a la escasa aplicación de prácticas de planificación financiera, lo que dificulta su gestión y sostenibilidad. El presente estudio tiene como objetivo analizar la importancia de la planificación financiera en el desarrollo empresarial desde la percepción de los beneficiarios de un programa de capacitación. La investigación adopta un enfoque cuantitativo, con un diseño no experimental y transversal de alcance descriptivo, y se apoya en la aplicación de encuestas a 154 empresarios y emprendedores, así como en una revisión documental de literatura académica. Los resultados, basados en la percepción de los participantes, sugieren que la capacitación financiera es valorada como una herramienta útil para apoyar la toma de decisiones, el control de recursos y la organización financiera de los negocios. Asimismo, los encuestados reconocen la pertinencia del programa y su aplicabilidad en la gestión empresarial. Se proponen estrategias orientadas a fortalecer la planificación financiera en el contexto local.Businesses located in urban and rural parishes of Zone 5 in Ecuador face constraints associated with a weak financial culture and the limited adoption of financial planning practices, which hinder their managerial capacity and long-term sustainability. This study aims to analyze the relevance of financial planning for business development from the perspective of the beneficiaries of a financial training program. The research adopts a quantitative approach with a non-experimental, cross-sectional, and descriptive design, based on the application of surveys to 154 entrepreneurs and business owners, complemented by a documentary review of academic literature. The results, grounded in participants’ perceptions, suggest that financial training is regarded as a useful tool to support decision-making, resource control, and the financial organization of businesses. In addition, respondents acknowledge the relevance of the program and its applicability to business management. Finally, strategies aimed at strengthening financial planning within the local context are proposed.As empresas localizadas em paróquias urbanas e rurais da Zona 5 do Equador enfrentam limitações associadas a uma fraca cultura financeira e à escassa aplicação de práticas de planejamento financeiro, o que dificulta sua gestão e sustentabilidade.
