A floristic inventory of the cloud forest of some localities of Landa de Matamoros municipality, Querétaro, was undertaken; this area is located in the Sierra Madre Oriental and is part of the Sierra Gorda Biosphere Reserve. In this zone the forest is  fragmented, but it has a relatively good conservation status in some localities such as Camarones, Neblinas, La Yesca, and La Joya del Hielo. A floristic list of vascular plants composed by 130 families, 465 genera and 774 species was obtained. A  distribution map of this vegetation type is included.

SummaryDelimiting the distribution of a species is a complex task because many determining factors are difficult to assess in the field. This is important because distribution is a key factor in the decision-making process for conservation. One example is the Bearded Wood Partridge Dendrortyx barbatus, a species endemic to the temperate forests of the Sierra Madre Oriental (SMO) mountain range in Mexico. Lack of knowledge of its distribution has generated confusion over the assignment of the correct risk category. With the aim of predicting the distribution area of the Bearded Wood Partridge and contributing to strategies for its conservation, we updated and extended the knowledge of its distribution by modelling its ecological niche using GARP and MaxEnt algorithms. We also analysed its environmental distribution using principal components analysis, and contrasted the two most important environmental variables with the species’s distribution based on vegetation type. We found that the area potentially occupied by this species covers 17,956 km2 according to GARP and 12,974 km2 according to MaxEnt. We suggest that there is a biogeographic barrier which limits the distribution of this species in the southern part of its range. The abiotic variables that best explain its distribution are average annual precipitation and elevation, both of which coincide well with the distribution of cloud forest. A redefinition of the current range as recognised by IUCN is proposed along with the need to change its national risk category.

We analyzed vegetation structure in a 1-ha plot of cloud forest at Santo Tomás Teipan (Oaxaca, Mexico). Considering its marginal location near the edge of a region covered by this vegetation type on the Sierra Madre del Sur, we examined to what extent this community differed from other cloud forest communities thriving under better conditions for this plant formation. Each individual with diameter at breast height (DBH) ≥2.5 cm was located in a system of coordinates; besides, its taxonomic identity, crown cover, DBH and total height as well as the height to the first branch and the crown base were recorded. Basal area (46.41 m2 ha-1), cover (44,247.33 m2 ha-1), and density (1,035 ind. ha-1) figures fall within the known range for the lower montane rain forests of tropical America. According to structure and composition, two strata were differentiated: a lower one (2 to 11 m), and an upper one (11 to 30 m). Overall dominance corresponded to Cornus disciflora, an upper stratum species. In the plot two topographic conditions were distinguished, namely lower ravine slope and hilltop, which seem to be associated to contrasting soil characteristics. Although this topographic heterogeneity does not match the structural homogeneity of the forest, we detected some clumped patterns for individual species that were preferentially distributed in one of these conditions. The structure of the forest at Teipan is comparable to that of similar forests, but its diversity is relatively low. This may be explained by the absence of taxa occurring in the adjacent dry tropical communities, unlike other cloud forests whose flora appears to be enriched with some elements typical of tropical moist communities with which they abut.

Background and aims – The intensive botanical prospections carried out in Gabon since the publication of the national checklist in 2006 have resulted in c. 34 300 new specimens (amounting to 30% of all collections made in the country) and an annual increase of 25 species in average. As a result, 5175 species of vascular plants are now recorded from Gabon, of which 650 are considered endemic. However, most of the recent discoveries have not yet been published. This paper is the first of a series documenting additions to the flora of Gabon, and new records of poorly known species. It concerns specifically new records from the Lower Ogooué Ramsar site, the third largest delta of Africa, and certainly the most intact, which includes 80% of the country’s wetlands and a wide variety of other habitats.Methods – The new records presented here come essentially from fieldwork conducted in Gabon between 2008 and 2016 by the authors and colleagues. Further information comes from the study of herbarium specimens in BR, BRLU, K, LBV, MO, P and WAG. For each species, information on distribution and ecology is given, and the studied Gabonese collections listed. In case of rare or range-restricted species, collections from other countries are also listed, and a distribution map is provided, as well as an evaluation of the conservation status based on the categories and criteria of the IUCN Red List.Key results – We report 18 additions to the flora of Gabon, including four genera new to the country (Capparis, Gisekia, Hoffmanniella and Leptochloa) and the first records of the neotropical Justicia secunda being naturalised in tropical Africa. New distribution records are also provided for 16 rare Gabonese endemics or near-endemics. Some species are also newly reported from Cameroon (Cissus leemansii, Salacia coronata) and Equatorial Guinea (Cissus leemansii, C. louisii, Lychnodiscus grandifolius, Placodiscus resendeanus, Rutidea gabonensis, Uvaria bipindensis). Two species, which were reported in the 2006 checklist based on misidentifications, are excluded from the Gabonese flora.

Resumen:Antecedentes y Objetivos: Son pocos los trabajos florísticos que se han publicado sobre licofitas y helechos (pteridofitas en conjunto) de Puebla, México, por lo que se considera muy probable que la riqueza de especies en el estado sea mayor a la que se tiene documentada hasta el momento.El objetivo de este trabajo es reportar nuevos registros de este grupo de plantas para la entidad, incluyendo su distribución municipal y altitudinal, así como el tipo de vegetación en que se presentan.Métodos: De 2010 a 2018 se efectuaron diversos viajes de recolección a distintas localidades de Puebla, durante los cuales se recolectaron y herborizaron ejemplares de licofitas y helechos, que fueron identificados y depositados en el Herbario de la Universidad Autónoma Metropolitana-Iztapalapa (UAMIZ). La información generada se confrontó con la lista de especies reportadas en la literatura para la entidad, lo que permitió reconocer los nuevos registros.Resultados clave: Se documenta por primera vez para Puebla la presencia de 32 especies y un híbrido de licofitas y helechos, la mayoría de las cuales pertenecen a las familias Pteridaceae, Dryopteridaceae y Aspleniaceae, crecen en bosque mesófilo de montaña y vegetación derivada de bosque tropical perennifolio, entre 250 y 2500 m de altura.Conclusiones: Los nuevos registros incrementan de 335 a 367 el número de especies de licofitas y helechos que habitan en el estado de Puebla y ponen en evidencia la necesidad de continuar con el trabajo de exploración en la entidad.Palabras clave: bosque mesófilo de montaña, bosque tropical perennifolio, pteridofitas, riqueza, tipo de vegetación.Abstract:Background and Aims: There are few published floristic contributions about the lycophytes and ferns (pteridophytes) from Puebla, so it is considered very likely that the specific richness of this group in the state is greater than what has been documented currently. The goal of this paper is to document the new records of this plant group for the state, including information about their municipal and altitudinal distribution and the type of vegetation they inhabit.Methods: Between 2010 and 2018, several collection trips to different localities of the state of Puebla were made to collect specimens of lycophytes and ferns. The material was identified and deposited in the Herbarium of the Universidad Autónoma Metropolitana-Iztapalapa (UAMIZ). The information obtained was compared with the list of species of Puebla reported in the literature, allowing recognition of the new records.Key results: The presence of 32 species and a hybrid of lycophytes and ferns was documented for the first time for Puebla, most of which belong to the families Pteridaceae, Dryopteridaceae and Aspleniaceae, growing in cloud forest and vegetation derived from tropical evergreen forest, betweenelevations of 250 and 2500 m.Conclusions: The new records increase the number of species of lycophytes and ferns reported for Puebla from 335 to 367 and highlight the need to continue with the exploration and field work in the state.Key words: cloud forest, pteridophytes, richness, tropical evergreen forest, vegetation type.

<p>Species composition, diversity, structure and microclimate were compared in two edge type of montane cloud forest (FF, edges with pine forest and FS, secondary shrubland) within a forest-edge-exterior gradient at Sierra de Manantlán Biosphere Reserve (Jalisco, Mexico). The cloud forest presented higher richness (126 species, 52 interior habitat specifi c) than pine forests (84) and shrublands (71). Richness and diversity were similar in FF, but species replacement was higher in FS. Density, diameter structure, basal area and canopy cover were major in FF than in FS. Microclimatic and soil condition, was gradual in FF edges and abrupt in FS edges. Tree species of the cloud forests (high density of seedlings and saplings &lt;5 cm diameter breast height) are colonizing the understory of adjacent pine forests, whereas in shrublands their establishment appears to be limited by competition with shrubs and herbaceous species and microclimatic conditions. Our results highlight the importance of considering edge type contrast in conservation and restoration of cloud forest in forest landscapes.</p>

Se analiza el papel que realiza una de las prácticas de conservación en los huertos de una comunidad mame en la Reserva de Biosfera Volcán Tacaná; Chiquihuite, Unión Juárez, Chiapas. Lo anterior, se llevó a cabo mediante la recolecta e identificación de las especies presentes en veinticuatro huertos de la comunidad y entrevistas semi estructuradas sobre el espacio de origen y el uso a la especie. Con esta información se elaboró una matriz de presencia-ausencia y una red de relaciones entre espacios, y se concluyó que existe una práctica de intercambio, principalmente entre los espacios huerto-montaña y huerto-huerto. La base de este intercambio es el uso y por ello la definición local del concepto de conservación, no se explica sin este concepto. INTERCHANGE OF PLANTS BETWEEN HOME GARDENS AND OTHER SPACES: A CONSERVATION STRATEGY FOR THE CLOUD FOREST OF THE TACANÁ VOLCANO IN CHIAPAS STATE, MEXICO? This paper analyzes the role played by one of the conservation practices carried out in the home gardens of a Mame community in the Tacaná Volcano Biosphere Reserve: Chiquihuite, in the Unión Juárez municipality of Chiapas State. This analysis was conducted through collecting and identifying the species present in 24 of the home gardens of the community as well as semi-structured interviews regarding the space of origin and use of the species. Based on this information, a presence-absence matrix was developed as well as a network of relationships between spaces. It was concluded that there is a practice of interchange, mainly between home garden and mountain, and between home garden and home garden. This interchange is based on use and therefore the local definition of conservation cannot be explained without this concept.
