Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, their distribution, and the threats affecting them. We compiled a global dataset of sampled earthworm communities from 6928 sites in 57 countries as a basis for predicting patterns in earthworm diversity, abundance, and biomass. We found that local species richness and abundance typically peaked at higher latitudes, displaying patterns opposite to those observed in aboveground organisms. However, high species dissimilarity across tropical locations may cause diversity across the entirety of the tropics to be higher than elsewhere. Climate variables were found to be more important in shaping earthworm communities than soil properties or habitat cover. These findings suggest that climate change may have serious implications for earthworm communities and for the functions they provide.

Resumen en inglés

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.

Resumen en inglés

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.

Resumen en inglés

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 inglés

Effective and targeted conservation action requires detailed information about species, their distribution, systematics and ecology as well as the distribution of threat processes which affect them. Knowledge of reptilian diversity remains surprisingly disparate, and innovative means of gaining rapid insight into the status of reptiles are needed in order to highlight urgent conservation cases and inform environmental policy with appropriate biodiversity information in a timely manner. We present the first ever global analysis of extinction risk in reptiles, based on a random representative sample of 1500 species (16% of all currently known species). To our knowledge, our results provide the first analysis of the global conservation status and distribution patterns of reptiles and the threats affecting them, highlighting conservation priorities and knowledge gaps which need to be addressed urgently to ensure the continued survival of the world’s reptiles. Nearly one in five reptilian species are threatened with extinction, with another one in five species classed as Data Deficient. The proportion of threatened reptile species is highest in freshwater environments, tropical regions and on oceanic islands, while data deficiency was highest in tropical areas, such as Central Africa and Southeast Asia, and among fossorial reptiles. Our results emphasise the need for research attention to be focussed on tropical areas which are experiencing the most dramatic rates of habitat loss, on fossorial reptiles for which there is a chronic lack of data, and on certain taxa such as snakes for which extinction risk may currently be underestimated due to lack of population information. Conservation actions specifically need to mitigate the effects of human-induced habitat loss and harvesting, which are the predominant threats to reptiles.
