The purpose of this study was to apply a phenomenological perspective in order to better understand hot flashes among 87 Maya, 60 non-Maya, and 8 uncategorized women from rural and urban communities in the state of Campeche, Mexico. We combined in-depth interviews with ambulatory hot flash monitors to show that while the majority of women had biometrically measurable sternal (75%) and nuchal (81%) hot flashes, they were less likely to report hot flashes (40%) during the study period. The number of biometrically measured hot flashes differed significantly across the four communities, but the number of reported hot flashes remained equally low. Across the entire sample, Maya and non-Maya women did not differ in the likelihood of demonstrating sternal and nuchal hot flashes, but Maya women were significantly more likely to push the buttons on the monitor to subjectively report a hot flash (48% vs. 27%). Qualitative results show that these findings can be explained by attention to the language of hot flashes (calores) and by the observation that hot flashes are naturalized by the hot and humid environment into everyday life. Women do not differentiate or separate the expression of hot flashes from the lived experience of the hot climate.

Resumen en español

El climaterio es la última etapa del ciclo reproductivo de la mujer caracterizada por una sintomatología que genera la búsqueda de alternativas más allá de la Terapia de Reemplazo Hormonal, la cual puede originar efectos adversos en la salud de las mujeres. En este estudio se identifica la herbolaria empleada para atender los síntomas asociados al climaterio de las mujeres de mediana edad de los municipios de Campeche, Hopelchén y Calakmul, en el estado de Campeche, México, analizando los factores sociales y ambientales que, desde la perspectiva de las entrevistadas, determinan la búsqueda, selección y conservación de estos recursos florísticos. Durante 2013 y 2015 se realizaron 132 entrevistas a mujeres entre 39 y 59 años de edad; sus respuestas fueron organizadas y sistematizadas en función de padecimientos percibidos, la herbolaria utilizada, formas de uso, áreas de obtención y conservación de los recursos florísticos en cada municipio.

Se identificaron 69 plantas (66 especies y tres plantas no identificadas taxonómicamente) y diez tipos de infusiones comerciales para atender 14 malestares, en mujeres que viven distintos contextos históricos, sociales, económicos y culturales. Predominaron los padecimientos somáticos, psicológicos, urogenitales y vasomotores. Las mujeres eligieron las plantas usadas de acuerdo a los siguientes factores: porque resultan un recurso complementario y alternativo ante una deficiente atención biomédica y por percepciones negativas hacia los medicamentos de patente; por experiencias positivas al usar herbolaria en otras etapas de su vida, conocimiento aprendido de sus entornos familiares y sociales y de los especialistas tradicionales que participan como referentes culturales; por la diversidad de formas regionales de entender y atender la salud en su vida cotidiana y durante el climaterio, y porque cuentan con espacios físicos donde pueden obtener y conservar herbolaria, destacando los huertos familiares; además de tener otros usos: alimenticio, ritual y ceremonial, la construcción, ornamental y comercial.

Resumen en inglés

The climacteric is the last stage of the reproductive cycle of women, which is associated with a symptomatology that generates the search for alternatives to control it beyond the Hormone Replacement Therapy, which can This study identifies the herbal medicine used to treat the symptoms associated with the climacteric of middle-aged women in the municipalities of Campeche, Hopelchen and Calakmul, in Campeche, México, analyzing the social and environmental factors that, from the perspective of the interviewees, determine the search, selection and conservation of these floristic resources. 132 women were interviewed between 2013 and 2015, from 39 to 59 years old; her answers were organized and systematized according to perceived illnesses, herbalism used, ways of use, and areas of obtaining and conservation of floristic resources in each municipality. 69 plants (66 species and three plants not taxonomically identified) and ten types of commercial infusions were identified to deal with 14 discomforts in women with different histories, living in different social, economic and cultural contexts. Somatic, psychological, urogenital and vasomotor disorders predominated. Women chose which plants to use according to the following factors: because they were a complementary and alternative resource in the face of poor biomedical care and negative perceptions towards patent medicines; for positive experiences when using herbalism in other stages of their life, knowledge learned from their family and social environments and from traditional specialists who participate as cultural references; for the diversity of regional ways of understanding and attending to health in their daily lives and during the climacteric; because women have spaces where resources can be obtained and conserved, especially family gardens and because they have other uses: nutritional, ritual and ceremonial, construction, ornamental and commercial.

Resumen en inglés

Background: Stress has been implicated as a factor in the presence and severity of symptoms during the menopausal transition. Our primary aim was to test the hypothesis that stress-sensitive biological measures and self-reported stress would be positively associated with a greater likelihood and intensity of hot flashes. Our secondary aim was to examine measures of stress in relation to the most often reported symptoms in Campeche, Mexico. We also hypothesized ethnic differences (Maya versus non-Maya) in relation to measures of stress and symptom reports. Methods: Participants aged 40–60 (n = 305) were drawn from multiple sites across the city of San Francisco de Campeche to achieve a generally representative sample. Measures included C-reactive protein (CRP), an indicator of inflammation; Epstein-Barr virus antibodies (EBV-Ab), an indicator of immune function; the Perceived Stress Scale (PSS); a symptom checklist; anthropometric measures; and a questionnaire that elicited symptoms, ethnicity (based on language, birthplace, and last names of the woman, her parents, and her grandparents) and ten dimensions of socioeconomic status (SES). The relationships between symptoms and stress-sensitive biological and self-reported measures were examined in bivariate analyses, and with logistic and linear regressions.

Results: The twelve most common symptoms reported, in descending order of frequency, were tiredness, muscle and joint pain, nervous tension, problems concentrating, feeling depressed, difficulty sleeping, headaches, feeling of ants crawling on the skin, loss of interest in sex, urinary stress incontinence, hot flashes, and night sweats. PSS scores were significantly associated with the likelihood of seven symptoms (yes/no), and with the intensity of ten symptoms after controlling for ethnicity, SES, education, cohabitation status, parity, smoking, body mass index, and menopausal status. The stress-sensitive biological measures of immune function (EBV-Ab and CRP) were not significantly associated with midlife symptoms. The PSS was associated with more symptoms among the Maya (e.g., feeling nervous/tense and having difficulty concentrating) than non-Maya. Conclusion: PSS scores were associated with the intensity, but not the likelihood, of hot flashes. Other symptoms were also associated with self-reported stress but not with physiological measures. Maya/non-Maya differences may indicate that either symptoms or stress were experienced and/or reported in culture-specific ways.

Objectives: The purpose of this study was to examine anti-Müllerian hormone (AMH) levels among women of Maya and non-Maya ancestry in the city of Campeche, Mexico. Levels of AMH can potentially predict age at menopause. Previous studies have indicated an early mean age at menopause among the Maya. Materials and methods: Women aged 40-60 (n = 97) participated in semistructured interviews, anthropometric measures, and blood samples. Maya/non-Maya ethnicity was determined by the last names, languages spoken, and birthplace of the woman, her parents, and her grandparents. AMH values were categorized as detectable (0.05-4.19 ng/mL) and undetectable (<0.05 ng/mL). Logistic regressions calculated odds ratios (OR) for undetectable AMH. Results: Women were categorized as Maya (n = 44), not Maya (n = 39), or not able to be clearly defined (n =14).In bivariate comparisons, women with detectable levels of AMH were younger, more likely to be pre-menopausal, and not Maya. Age, menopausal status, and ethnicity remained significant in a logistic regression models after controlling for age at menarche. Maya women were more than five times as likely to have nondetectable AMH levels as non-Maya women. Discussion: Increasing age and progression through the menopausal transition were both associated with declining levels of AMH. The association between Maya ethnicity and a lower likelihood of detecting AMH is consistent with the early ages at menopause reported in previous studies. We considered a rapid life history model as an explanatory framework, and suggest, from an ecological perspective, that future research should consider measures of developmental stress that may compromise ovarian reserves.

Antecedentes y objetivos: Se presenta el primer listado florístico de las playas y dunas costeras de México, actualizado y respaldado por ejemplares de herbario. Métodos: Se revisaron 14 herbarios nacionales y extranjeros. Se sobrepuso una retícula de 2 x 2 km al mapa de la costa y de las dunas costeras de México para referir todos los registros que corresponden a 2180 sitios con 12,419 ejemplares de plantas. Se calcularon índices de diversidad, similitud, diversidad taxonómica y redundancia. Resultados clave: La flora registrada consta de 153 familias, 897 géneros y 2075 especies de plantas vasculares, las cuales representan 9.5% de la flora vascular de México. Las cinco colecciones con índices de redundancia altos IR0.7 son los herbarios de la Universidad Nacional Autónoma de México (MEXU, IR=0.9), del Centro de Investigación Científicas de Yucatán (CICY, IR=0.8), y los del Centro de Investigaciones Biológicas del Noroeste (HCIB), el Instituto de Ecología, A.C. (XAL) y el del Museo de Historia Natural de San Diego (SD), cada uno con un IR de 0.7. Se reconocen cinco regiones florísticas que corresponden a los mares de México. El Pacífico Norte tiene mayor diversidad taxonómica y el Pacífico Sur menor diversidad taxonómica. El Golfo de California, Golfo de México y Mar Caribe tienen diversidades taxonómicas similares. Las especies con más registros son Trianthema portulacastrum (165), Crotón punctatus (107), Echites umbelllatus (106) e Ipomoea pes-caprae (90). Por el carácter de ecotono de las dunas costeras, la mayoría de las especies se comparten con los tipos de vegetación vecinos (selvas, matorrales, y humedales como las marismas y manglares). Conclusiones: Esta primera lista de la flora en playas y dunas de México es la base para múltiples estudios florísticos regionales y locales, biogeográficos, y ecológicos; además, que será importante para su uso en temas de impacto ambiental y manejo costero.

Resumen en inglés

Background and Aims: The first updated floristic checklist, supported with herbarium specimens, is presented for beaches and coastal sand dunes of Mexico. Methods: The analysis is based on the revision of 14 national and foreign herbaria. A 2 x 2 km grid was placed over a map of the coastal sand dunes of Mexico to reference the herbarium records, corresponding to the 2180 sites and 12,419 examples of plants documented. Indices of diversity, similarity, taxonomic diversity, and redundancy were calculated. Key results: The flora of the beaches and coastal sand dunes of Mexico consists of 153 families, 897 genera, and 2075 species of vascular plants. These represent 9.5% of the vascular flora of Mexico. The herbaria with high indices of redundancy (IR0.7) are the herbarium of the Universidad Nacional Autónoma de México (IR=0.9), the Centro de Investigación Científica de Yucatán (CICY, IR=0.8), the Centro de Investigaciones Biológicas del Noroeste (HCIB), the Instituto de Ecología, A.C. (XAL) and the Natural Museum in San Diego (SD), each with an IR of 0.7. Five floristic regions are clearly recognized, which correspond to the seas of Mexico. The North Pacific has the highest taxonomic diversity and the South Pacific has the least. The Gulf of California, Gulf of Mexico and the Caribbean Sea have very similar taxonomic diversity. The species with the most recorded occurrences are Trianthema portulacastrum (165), Croton punctatus (107), Echites umbellatus (106) and Ipomoea pes-caprae (90). Considering the ecotonal nature of the ecosystem, most dune plants are shared with neighboring vegetation (forests, scrubs, wetlands, such as marshes or mangrove swamps). Conclusions: This first checklist of the flora of beaches and coastal dunes is the baseline for multiple future studies: floristic, biogeographic, and ecological. Moreover, this list will be important if used in environmental assessments and coastal zone plans.

Objective: The purpose of this study was to better understand the experience of calores (hot flashes) in the state of Campeche, Mexico, and characteristics of women’s lives. This study was carried out to understand the sociocultural context of women’s lives before conducting a larger semistructured survey in the same communities. Methods: Eighty-five women from rural and urban settings participated in open-ended interviews about the menopausal transition, with particular attention to hot flashes. Univariate and logistic regression analyses identified potential determinants of hot flashes. Qualitative responses were analyzed for central themes from the 40 women who experienced ‘‘calores’’ associated with menopause at the time of interview. Results: The word ‘‘calores’’ was used to describe a variety of sensations and experiences related to the hot climate, infections, going in and out of air-conditioning, emotional stress, and physical exertion, as well as the symptom associated with menopause. In quantitative analyses, the likelihood of experiencing hot flashes varied by menopause status and rural/urban residence. In qualitative analyses, themes that characterized the lives of women with hot flashes were as follows: the search for, and the availability of, biomedical care; presence or absence of networks of social support; marital status and quality of the relationship; and occupational stress. Conclusions: Hot flash questionnaires can elicit different symptom frequencies depending on the language used and the sociocultural context of women’s lives. Qualitative findings suggest that the themes most likely to influence the perception and experience of hot flashes in Campeche are biomedicine, social support, marriage, and stress.

Resumen en español

Con el objetivo de estimar la biomasa y el carbono acumulado en bosques de pino (Pinus maximinoii), encino (Quercus rugosa), roble (Quercus robur) y ocote (Pinus patula), en 1 ejidos de la región Frailesca de Chiapa, se seleccionaron 22 parcelas de 500 m² (dos por cada ejido); en las que se determinaron la altura (H), la edad (años) y el diámetro normalizado (DN) de 358 árboles. Se ajustaron ecuaciones de regresión entre la biomasa acumulada (BMt) y la edad de cada árbol. Los ajustes resultaron estadísticamente significativos para el modelo exponencial y=b·ec·x. Se demuestra que, a partir de la edad del árbol, es posible estimar la biomasa total acumulada y que la mayor acumulación, tanto de biomasa como de carbono, se produjo en los bosques de pino y la menor en los de roble, debido a su estado fisiológico determinado por la menor edad del arbolado. Los bosques de pino registraron un almacén de 158 Mg ha-¹, seguido del encino con 17 Mg ha-¹. La especie que menos carbono almacenó fue el roble con 5.9 Mg ha-¹. De los sitios estudiados, los bosques del ejido “24 de Febrero” presentaron mayor captura potencial de carbono.

Resumen en inglés

Twenty-two 500 m² plots (two for each ejido) were selected in 11 ejidos of La Frailesca region of Chiapas in order to estimate the biomass and accumulated carbon in pine (Pinus maximinoii), oak (Quercus robur), holm oak (Quercus rugosa) and Mexican weeping pine (Pinus patula). The height (H), age (years) and normalized diameter (ND) of 358 trees were determined in these plots. Regression equations between the accumulated biomass (BMt) and the age of each tree were adjusted. The adjustments were statistically significant for the exponential model y=b·ec·x. This study proves that the total accumulated biomass can be estimated based on the age of the tree, and that the largest accumulation of both biomass and carbon occurred in the pine forests, and the lowest, in the oak forests; this is due to their physiological status, as the latter trees are younger. Pine trees had a storage of 158 Mg ha-¹, followed by holm oaks, with 117 Mg ha-¹; the species with the lowest value was oak, with 5.9 Mg ha-¹. Of all the studied sites, the forests of the “24 de Febrero” ejido had the highest potential for carbon capture.

Banco Chinchorro is the largest reef in the Mexican Caribbean. Historically, spiny lobster, queen conch and over 20 other reef species have been exploited here. Multispecies intervention management from an ecosystem perspective has been developed in this area; however, an assessment of the effects of such practices on ecosystem health is required. Five quantitative trophic models were constructed using Ecopath with Ecosim. The results show that, in terms of biomass, benthic autotrophs are the dominant group in all communities. Ecosystem Network Analysis indices showed that Cueva de Tiburones was the most mature, developed, complex and healthy subsystem, but, El Colorado and La Baliza were the subsystems most resistant to disturbances. The fisheries mainly concentrate on primary (La Baliza and Cueva de Tiburones sites) and secondary consumers (La Caldera, Chancay, and El Colorado). The greatest propagation of direct and indirect effects, estimated by Mixed Trophic Impacts and Ecosim simulations, were generated by the benthic autotrophs, small benthic epifauna, benthic-pelagic carnivorous fish and benthic carnivorous fish, among others. In contrast, the System Recovery Time showed different patterns among subsystems, indicating several compartments that reduce resilience. Considering the structure, dynamics, trophic functioning and ecosystem health of Banco Chinchorro, its ecological heterogeneity highlights the need for the design of a specific (by subsystem) management strategy, particularly because different species or functional groups present greater sensitivity to human interventions in each community.
