Post-fire successional response of Lepidoptera communities in the Sierra Madre Oriental mountain range by Jane Friesen, Rebecca

“…Changing forest fire regimes may have serious implications for forest health, impacting the local economy which depends heavily on ecosystem services in the park. Lepidoptera are important forest pollinators and are potentially useful indicators due to their sensitivity to ecological disturbances, therefore their response to disturbance merits study. …”

Contenido de carbono total en los componentes de especies arbóreas y arbustivas en áreas con diferente uso, en el matorral espinoso tamaulipeco, en México by Yerena Yamallel, José Israel, Jiménez Pérez, Javier, Aguirre Calderón, Oscar Alberto, Treviño Garza, Eduardo Javier

“…ABSTRACT Total carbon content coefficients were generated for basal biomass units for each of the components (stem, branches, small branches, leaves and bark) of trees and shrubs species in three areas with different historical use (traditional agriculture, extensive foraging and clearcut) on tamaulipan thornscrub, which will allow estimating carbon stored in this type of ecosystem. The total carbon content expressed as a percentage of biomass was determined with the Solids TOC Analyzer equipment that analyzes the total carbon contents in solid samples by complete combustion. …”

Litterfall production and nutrient deposition through leaf fallen in three tamaulipan thornscrub communities, north-eastern Mexico by López Hernández, Juan Manuel, Maiti, Ratikanta, Gómez Meza, Marco Vinicio, González Rodríguez, Humberto, Cantú Silva, Israel, Ramírez Lozano, Roque Gonzalo, Moreno Pando, Maricela, Estrada Castillón, Andrés Eduardo

“…Litterfall and the contents of macro- and micro-nutrients derived from its decomposition contribute greatly to the growth and productivity of forest ecosystem. The present study was undertaken to know the variability during two years in the deposition of litterfall and deposition of nutrients through leaf fallen litterfall in three sites of the state of Nuevo Leon (Los Ramones, China and Linares), north-eastern Mexico, which encompasses the Tamaulipan thornscrub plant community. …”

Evaluación antagonista in vitro de bacterias aisladas de ecosistemas marinos en contra de Vibrio parahaemolyticus AHPND como patógeno de importancia acuícola. by Cázares Jaramillo, Gabriel Enrique

“…The objective of this study was to evaluate and characterize marine ecosystem bacteria against Vp. To achieve this, the antagonistic effect of isolates against a pathogenic strain of Vp was evaluated using cross-streak tests and the well diffusion test, the latter with two variants; one with bacterial cell culture and another the cell free supernatant. 17 bacterial isolates showed zones of inhibition of 0.2 to 1.7 cm in the cross streak test, on the other hand, three evidenced halos of inhibition of 2.06 to 2.46 cm by the well diffusion test with bacterial cell culture, while 5 bacteria Marine showed inhibition of 1.76 to 3.66 by the well diffusion test with cellfree supernatant. …”
