Resumen: Se realizó el inventario de la mastofauna en el Bosque Mesófilo de Montaña del Municipio de San Felipe Usila en el Distrito de Tuxtepec, Oaxaca, durante cinco periodos mensuales de julio a noviembre de 2005.  Se registraron representantes de cinco ordenes, 11 familias, 22 géneros y 23 especies, de las cuales una es endémica, siete están incluidas en alguna categoría de riesgo de acuerdo a normas nacionales e internacionales y cuatro son consideradas indicadoras de buena calidad ambiental, que incluyen tres quirópteros y un carnívoro.  Las especies más abundantes fueron el murciélago Sturnira ludovici y el roedor Peromyscus mexicanus. Palabras clave: Riqueza de especies, Bosque Mesófilo de Montaña, San Felipe Usila, Oaxaca, México. Abstract:  A mammal inventory of the cloud forest area of San Felipe Usila town, Tuxtepec, Oaxaca was carried out.  The Santa Cruz Tepetotutla and San Antonio del Barrio communities were sampled between July and November 2005.  We recorded five orders, 11 families, 22 genera, and 23 species, one species is endemic, seven are considered endangered according to national and international laws, and four are indicators of good quality of the environment, included three bats and one carnivore.  The most abundant species was the bat Sturnira ludovici and the rodent Peromyscus mexicanus. Key words: Species richness, Cloud forest, San Felipe Usila, Oaxaca, Mexico.

Abstract. A small rodent species was studied in two agroecosystems from Yucatan: (1) a traditional cornfield and (2) an induced grassland. A total of 87 individuals of six species in two families (Heteromyidae y Cricetidae) were captured rendering an effort of  2,544 nights/trap. Heteromys gaumeri and Peromyscus yucatanicus were the most abundant species with 57.5% and 17.2% of total captures, respectively. Highest captures were recorded in the traditional cornfield and the highest species richness was obtained in the grassland. No significant differences in diversity were found between sites (p > 0.05). It seems that the cornfield plays an important role on both the diversity and population dynamics of small rodents because it presents the highest values in captures, density, recruitment, and in reproductive individuals. This may be related to a greater variety of cultivated plant species in this agroecosystem. Key words: Small mammals, rodents, Cornfield, Grassland, Yucatan, Mexico. Palabras clave: Pequeños mamíferos, roedores, milpa, pastizal, Yucatán, México.

Resumen: La degradación de la calidad del agua y de la vegetación de ribera en los ríos mediterráneos es hoy en día un importante problema ambiental.  El río Mijares discurre por la provincia de Teruel desde su nacimiento en la Sierra de Gúdar -municipio de El Castellar-, a 1.500 metros de altura y forma impresionantes cañones y paisajes fluviales en este tramo alto de un gran valor ambiental. Sin embargo, en este trabajo se analiza de manera cualitativa la calidad de sus aguas y de la vegetación de ribera para mostrar que este gran recurso territorial para el desarrollo rural de la zona presenta unos niveles de contaminación preocupantes. Posteriormente se argumenta a la luz de los datos obtenidos, que las áreas en despoblación y con muy escasa presencia humana también presentan problemas ambientales que están relacionados con una presencia institucional muy débil en este tipo de territorios.   Palabras clave: cursos fluviales, problemas ambientales, despoblación, Teruel.   Abstract: The degradation of water quality and riparian vegetation in Mediterranean rivers is today a major environmental problem. The upper basin of the Mijares river flows through the province of Teruel from its source in the municipality of El Castellar at 1,500 meters high and forms some impressive canyons and river landscapes in this upper section of great environmental value. However, this research qualitatively analyzes the quality of its waters and the riverside vegetation to show that this great territorial resource for rural development in the area presents important levels of degradation. Subsequently, it is discussed in the light of the data obtained, that the areas in depopulation and with very little human presence also present environmental problems that are related to a very weak institutional presence in this type of territories.   Key words: rivers, environmental problems, depopulation, Teruel

Pleurothallis minutilabia, a species unique in subsection Macrophyllae-Fasciculatae because of the minute, highly reduced lip, is described and compared to the most similar species in the subsection. It is also compared morphologically to Pleurothallis kaynagata from section Abortivae, to which P. minutilabia is not related, but which also possesses a highly reduced lip. The morphology of the flower of P. minutilabia is discussed briefly in relation to possible pollination mechanisms. The distribution, restricted to Zamora Chinchipe, southern Ecuador, and the conservation status are addressed. Key words / Palabras clave: cloud forest, Ecuador, labellar morphology, Pleurothallis, pollination

ES Para establecer las razones por las que un hablante elige un enunciado irónico por encima de uno literal es necesario evaluar la mente del hablante y su intención al emplear la ironía verbal en un contexto comunicativo específico. Con base en lo anterior, el objetivo de este estudio es analizar la manera en que adolescentes de 12 y 15 años reflexionan sobre las funciones de la ironía verbal en dos tipos de enunciados irónicos: agradecimiento y ofrecimiento. Treinta y dos adolescentes se enfrentaron a diferentes situaciones comunicativas que finalizaban con un enunciado irónico, y mediante un guion de preguntas se indagó sobre las funciones que los participantes atribuían a cada enunciado irónico y sobre el tipo de conocimientos en los que basaban sus reflexiones. Los resultados muestran diferencias debidas a la edad en la cantidad y calidad de las reflexiones presentadas por los participantes. Palabras clave: DESARROLLO LINGÜÍSTICO TARDÍO, IRONÍA VERBAL, REFLEXIÓN METALINGÜÍSTICA, FUNCIÓN DE LA IRONÍA, TEORÍA DE LA MENTE EN To establish the reasons behind a speaker’s choice to use an ironic expression over a literal one, it is necessary to evaluate the speaker’s mind and his/her intention to employ irony in a specific communicative context. Taking this into account, the purpose of this study is to analyse the way in which adolescents ages 12 and 15 reflect on the functions of verbal irony in two types of ironic expressions: ironic thanking and ironic offering. Thirty-two subjects were faced with different communicative situations ending with an ironic remark and were asked about the functions they attributed to each remark and on what sort of knowledge they based their responses. Results show age-based differences in the amount and quality of the reflections presented by the participants. Key words: LATER LANGUAGE DEVELOPMENT, VERBAL IRONY, METALANGUAGE, FUNCTIONS OF IRONY, THEORY OF MIND IT Per stabilire i motivi che spingono un parlante a usare un enunciato ironico al posto di uno letterale, è necessario valutarne la mente e le intenzioni nell’usare l’ironia verbale in un determinato contesto comunicativo. Con queste premesse, il presente studio si propone di analizzare in che modo adolescenti di 12 e 15 anni riflettono sulle funzioni dell’ironia verbale in due tipi di enunciati ironici: ringraziamento e offerta. Dopo essere stati messi di fronte a diverse situazioni comunicative che si chiudevano con un enunciato ironico, a 32 adolescenti è stato chiesto di rispondere a una serie di domande sulla funzione che ciascuno/a di loro attribuiva a ogni enunciato e di dire in base a cosa avevano optato per quella funzione. I risultati mostrano differenze in base all’età nella quantità e nella qualità delle riflessioni fatte dai/dalle partecipanti.
