A New Species

Eleutherodactylus uno n. sp . is described from the oak-pine zone of the Sierra Madre del Sur, in the Mexican state of Guerrero . The new species cannot be associated with any currently recognized supraspecific division within the genus and demonstrates the unsatisfactory nature of attempts to cluster the approximately 400 known species into groups.

AbstractThe diet and habitat ofLeptomeryxsp. from the Late Uintan Yolomécatl Formation of NW Oaxaca, SE Mexico were inferred using dental enamel carbon and oxygen isotopic relationships, and compared with those of congeneric species from temperate North America. Results show thatLeptomeryxsp. fed on C3 plants and lived in open forest or forest/savanna ecotone. The palynoflora and co-occurrence of perissodactyls and artiodactyls that live in an environment like that ofLeptomeryxsupport this interpretation. Further, both records disclose that in NW Oaxaca (southern North America) tropical conditions prevailed at that time, unlike that of temperate North America.

El balance reflexivo del trabajo de campo que presentamos en este artículo se remonta a abril de 2017, cuando realicé un retiro en San Mateo Río Hondo, Oaxaca, con el objetivo de escribir algunas partes de mi tesis de doctorado. Un amigo me había aconsejado este lugar por su tranquilidad, su aislamiento en la montaña, como un lugar perfecto para estudiar, sin muchos turistas. Efectivamente, es uno de los pueblos en el corazón de la Sierra Madre del Sur, poco conocido y distanciado de la ruta hacia las playas.En 2018, al momento de elegir un caso de estudio para el proyecto de posdoctorado Turismo alternativo en México, quise utilizar mis recuerdos y observaciones básicas para formular unas hipótesis de partida alrededor de los impactos locales del turismo. Se expone esto en una primera parte del trabajo, antes de develar cómo la realidad del campo y mi situación laboral condicionaron la metodología. La segunda parte está dedicada a contar algunas de nuestras observaciones respecto a la estructura espacial y la actividad económica turística. Esto me llevó, como se describe en una tercera parte y con base en los perfiles y prácticas de los turistas, a reformular una problemática más precisa acerca de la relación entre turismo y urbanización.

Conserving the geological heritage in Jalisco implies, identifying, classifying and substantiating the importance of geosites in Jalisco and its subsequent dissemination through geotourism. The above can contribute to the creation of geo-park (s), according to the definition and methodology of UNESCO, with the consequent economic benefit to the inhabitants of these regions. The disclosure of geological information encourages an appreciation and care of abiotic resources (rocks, minerals, fossils, morphology, soil and water), especially prior to productive activities, minimizing their damage or avoiding building in areas with geological hazards. Jalisco has a great geodiversity, compared to other states, its history begins approximately 200 million years ago, recorded in the Sierra Madre del Sur and in the Jalisco Block, the most recent volcanic and tectonic activity is recorded in the Volcanic Belt Mexican. The previous provinces, together with the Sierra Madre Occidental and the Central Plateau, contain a wide range of rocks, fossil areas of economic and cultural importance (most of 70 places) and relate the geological history and its dynamics. Geothermal activity, is present in 400 locations.

Chusquea is the most diverse among woody bamboo genera, with 174 described species. Not surprisingly, Chusquea is the most diverse bamboo genus in Mexico, and with the description of C. nedjaquithii the number of species will increase to 20, representing almost 45% of the total Mexican woody bamboo diversity. Based on fieldwork in the Mexican state of Oaxaca and revision of herbarium specimens we describe and illustrate C. nedjaquithii, a species endemic to the Sierra Madre del Sur in Oaxaca, Mexico. Chusquea nedjaquithii is similar to C. liebmannii but differs in having culms with deciduous hairs, an oblate central bud and fewer subsidiary buds, strongly geniculate branches in one row forming an incomplete verticil, oblique foliage leaf blade bases, and longer inner ligules in the foliage leaves. A key to the Mexican Chusquea species based on vegetative characters is provided.
