Niche Modelling

The Nelson´s small-eared shrew, Cryptotisnelsoni (Merriam, 1895), is a critically endangered species, endemic to cloud forests in Los Tuxtlas, a mountain range along the Gulf of Mexico coast. This species is only known from the type locality and its surroundings. Here we present new records that extend its distribution approximately 7 km southeast of the type locality and report more specimens near to the type locality. We also identified climatically suitable areas for C.nelsoni using ecological niche modelling and investigated the sampling bias to identify poorly sampled areas in Los Tuxtlas. We suggest that the scarcity of records in other areas with suitable climatic conditions throughout Los Tuxtlas is a consequence of incomplete surveys. We strongly highlight the importance of continuing surveying this critically endangered shrew using more efficient sampling techniques to better understand its current distribution and conservation status. Despite all known localities occurring inside Los Tuxtlas Biosphere Reserve, deforestation and climate change still pose current and future threats to this species.

Biological Value

AbstractKristianstads Vattenrike Biosphere Reserve [KVBR] is a UNESCO designated area of Sweden possessing high biological value. Although several studies on tardigrades inhabiting Sweden have been performed, the KVBR area has been neglected. The current study investigates the tardigrade fauna of five areas of the biosphere reserve and includes 34 samples of different substrates analysed quantitatively and qualitatively. In total, 33 species of tardigrades were found in the samples, including 22 new records for the Skåne region, 15 new records for Sweden, and four species new to science. Mesobiotus emiliae sp. nov., Xerobiotus gretae sp. nov., Itaquascon magnussoni sp. nov., and Thulinius gustavi sp. nov. were described with an integrative approach (when possible) using morphological characters (light, electron scanning, and confocal laser scanning microscopies) and molecular markers (ITS2, 18S, 28S, cox1). A new protocol to increase morphological data was developed recovering mounted specimens within old slides for SEM analysis. Emended diagnoses for the genus Itaquascon and the transfer of Platicrista itaquasconoide to the genus Meplitumen are proposed. This study enriches the knowledge of the tardigrade biodiversity both within the KVBR and in Sweden and contributes to the rapidly increasing number of tardigrade species reported worldwide. The 33 species identified in the KVBR area represents 28% of all water bear species found in Sweden so far. The restricted study areas and limited number of samples collected suggests that the KVBR is very rich of tardigrades.

Different Levels

The Los Tuxtlas Reserve has been heavily deforested and fragmented since the 1970’s. Although the flora of Los Tuxtlas has been described previously, most floristic lists come from the large forest reserve of the Los Tuxtlas field station. Here we present a check list of Angiosperms recorded in 45 rainforest fragments (< 1 to 266 ha) located in three landscapes with different levels of deforestation. We sampled all trees, shrubs, lianas, palms and herbs with diameter at breast height (dbh) Ā 2.5 cm within ten 50 m x 2 m plots per fragment. We recorded 9,435 plants belonging to 73 families and 372 species. Fabaceae, Rubiaceae, and Moraceae were best represented. Eight species are classified as Endangered by the Mexican government, and five are human-introduced species. We conclude that the conservation and restoration of all the remaining rainforest fragments are necessary to effectively preserve the plant diversity of this region.

Resumen. Se elaboró una lista de los mamíferos silvestres de la Reserva de la Bíosfera "El Triunfo". Se colectaron en campo, entre mayo de 1994 y agosto de 1996, 136 ejemplares (píel y cráneo), 72 huellas en molde de yeso y 25 restos óseos. También se consultaron las bases de datos de nueve museos nacionales y extranjeros en los que existen 528 registros para la reserva. Se registraron 112 especies, 75 géneros, 26 familias y 10 órdenes. El 86.6% de las especies pertenecen a los órdenes Chiroptera, Rodentia y Carnivora. Así mismo 39 especies están clasificadas con alguna categoría de riesgo. Comparada con Los Tuxtlas, El Ocote y Montes Azules, El Triunfo tiene el menor porcentaje de similitud de especies (indice de Szymkiewicz-Simpson). Los datos aportados por el estudio pueden ser de utilidad en los planes de manejo de la reserva, pero deben ser completados con investigación sobre distribución y abundancia en diferentes tipos de vegetación.Abstract. We compiled a checklist ofwild mammals from "El Triunfo" Biosphere Reserve. From May 1994 to August 1996 we collected 136 specimens (skin and skull), 72 footprints gypsum molds and 25 fragments osseous. Were reviewed also data of9 Mexican and foreign museums in which 528 records are present. The checklist is composed of 112 species, 75 genus, 26 families and 10 orders. 86.6% of these species belong to Chiroptera, Rodentia and Carnívora Orders. 39 species are cIassified in one of the categories of conservation concern. Compared with Los Tuxtlas, El Ocote and Montes Azules reserves, the mastofauna richness of "El Triunfo", has the lowest percentage of similarity among species (Szymkiewicz-Simpson' s index). The data obtained from this survey, can be used as part ofthe management plans of this reserve. However must be completed with research about distribution and abundance in several kinds of vegetation.Palabras clave: El Triunfo, mamíferos, diversidad, conservación, Síerra Madre de Chiapas.
