Characterization of lignocellulolytic activities from fungi isolated from the deep-sea sponge Stelletta normani por Balestrini, Raffaella, Batista García, Ramón Alberto, Sutton, Thomas, Jackson, Stephen A., Tovar Herrera, Omar Eduardo, Balcázar López, Edgar, Sánchez Carbente, María del Rayo, Sánchez Reyes, Ayixon, Dobson, Alan D. W., Folch Mallol, Jorge Luis

“…While bacteria derived from deep-sea marine sponges have been studied, much less information is available on fungal biodiversity associated with these sponges. Following screening of fourteen fungi isolated from the deep-sea sponge Stelletta normani sampled at a depth of 751 metres, three halotolerant strains (TS2, TS11 and TS12) were identified which displayed high CMCase and xylanase activities. …”

High diversity and suggested endemicity of culturable Actinobacteria in an extremely oligotrophic desert oasis por Arocha Garza, Héctor Fernando, Canales del Castillo, Ricardo, Eguiarte, Luis E., Souza, Valeria, De la Torre Zavala, Susana

“…To test the distribution of Actinobacteria populations on a small scale, we chose the extremely oligotrophic and biodiverse Cuatro Cienegas Basin (CCB), an endangered oasis in the Chihuahuan desert to assess the diversity and uniqueness of Actinobacteria in the Churince System with a culture-dependent approach over a period of three years, using nine selective media. …”

Fire response of the endangered Pinus culminicola stands after 18 years in Cerro El Potosí, northeast Mexico por Arévalo Sierra, José Ramón, Estrada, Eduardo, Encina, Juan A., Villarreal, José A., Escobedo, Job R., Morales, Yaretzi, Cantú, Israel, González Rodríguez, Humberto, Uvalle Sauceda, José Isidro

“…Significant differences between control and burned plots were found with respect to regeneration, species composition, evenness and soil nutrients, suggesting that fire could promote natural regeneration and biodiversity in these communities. Research highlights: Management efforts are necessary to maintain a natural fire regime and ensure grazing exclusion in order to favor the conservation of the community dominated by this rare species P. culminicola. …”
