Contribución al conocimiento de los hongos (macromicetos) de la Sierra Fría, Aguascalientes

Contribution to the knowledge of the fungi (Macromycetes) from the Sierra Fría, Aguascalientes México. A taxonomic study based on the analysis of 372 species of macromycetes from Sierra Fría, Aguascalientes México is presented. The collected species belong to the subdivision Ascomycotina (30) and Basidiomycota (342). Amanita caesarea, A. citrina A. flavoconia, A. pantherina, Astraeus hygrometricus, Boletus edulis, Calvatia cyathiformis, Clitocybe gibba, Cyathus olla, Daldinea concentrica, Laccaria amethystima, Lycoperdon candidum, L. perlatum, Mycena acicula, Schizophyllum commune, Russula emetica, R. mexicana, Stropharia semiglobata and Polyporus arcularius were the most extent distribution species. The most species were collected in forest oak. We discuss the use and importance concerning their mycorrhizal association and edibility. 12 mycorrhizal species, 106 edibles, 34 poisons, 36 wood destroying and 134 not edibles were registered.Se presenta un estudio taxonómico basado en el análisis de 372 especies de hongos de la Sierra Fría, Aguascalientes México.

Boletus edulis, Russula emetica, Agaricus brunnescens, Chlorophyllum molybdites, Stropharia semiglobata, Amanita caesarea, Laccaria amethystina, Amanita flavoconia y Clitocybe gibba fueron las especies más ampliamente distribuidas en la entidad, mientras que las familias con mayor representatividad fueron Tricholomataceae (75 especies), Boletaceae (50), Russulaceae (31), Strophariaceae (26) y Amanitaceae (29). La mayor riqueza de especies se concentra en los bosques de encino. Amanita muscaria, Boletus edulis y Psathyrella spadicea se incluyen como especies amenazadas, mientras que Psilocybe caerulipes está sujeta a protección especial según la norma oficial mexicana (NOM-059-ECOL-2010).A study based on the analysis of 306 species of Agaricales is presented. Boletus edulis, Russula emetica, Agaricus brunnescens, Chlorophyllum molybdites, Stropharia semiglobata, Amanita caesarea, Laccaria amethystina, Amanita flavoconia y Clitocybe gibba were the species widely distributed within the state Tricholomataceae with 75 species, Boletaceae 50, Russulaceae 31, Strophariaceae 26 and Amanitaceae 29 were the best represented in the state of Aguascalientes. Most species were collected in oak forests. Amanita muscaria, Boletus edulis and Psathyrella spadicea are considered as threatened species, while Psilocybe caerulipes is subject to special protection by oficial regulations (NOM-059- ECOL-2010)

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
