Última Assessment of the occurrence and richness of arbuscular mycorrhizal fungal spores by direct analysis of field samples and trap culture - a comparative study Anais da ABC (AABC) LEAL,PATRÍCIA L.; CARVALHO,TEOTONIO S. DE; SIQUEIRA,JOSÉ OSWALDO; MOREIRA,FATIMA M.S.. ABSTRACT In this work, we hypothesized that two spore-based methods, direct analysis of field samples and trap cultures, simultaneously used for assessment of occurrence and species richness of arbuscular mycorrhizal fungi (AMF) may vary in their efficiency according to the environmental conditions and the total AMF species richness of the evaluated ecosystem. The performance of both methods was analyzed based on two datasets: 1) a complete site x species matrix compiled from two studies in different land uses in the Amazon using direct analysis of field samples and trap cultures. 2) Total number of AMF morphotypes detected by both methods in published manuscripts across several ecosystems. From dataset 1, direct analysis of field samples revealed 57...

Blake Colegio de Postgraduados Oros Nakamura, Dilhery. La superficie de los bosques naturales en México se ha visto mermada debido a la gran demanda de productos maderables y a la falta de un adecuado manejo. El Gobierno Federal a través de la Comisión Nacional Forestal (CONAFOR) incentivó el establecimiento de plantaciones forestales comerciales tratando de revertir el deterioro y contribuir a satisfacer la demanda nacional de productos maderables. Sin embargo, existe un desconocimiento sobre el efecto positivo o negativo de los monocultivos en elecosistema, particularmente en la biodiversidad. Los objetivos de este trabajo fueron evaluar, analizar y comparar la diversidad vegetal del sotobosque en condiciones de plantación, de vegetación riparia y de pastizal, a través de la composición florística e...

Ano: 2012 URL: http://hdl.handle.net/10521/866 Environmental DNA metabarcoding reveals and unpacks a biodiversity conservation paradox in Mediterranean marine reserves ArchiMer Boulanger, Emilie; Loiseau, Nicolas; Valentini, Alice; Arnal, Véronique; Boissery, Pierre; Dejean, Tony; Deter, Julie; Guellati, Nacim; Holon, Florian; Juhel, Jean-baptiste; Lenfant, Philippe; Manel, Stéphanie; Mouillot, David. Although we are currently experiencing worldwide biodiversity loss, local species richness does not always decline under anthropogenic pressure. This conservation paradox may also apply in protected areas but has not yet received conclusive evidence in marine ecosystems. Here, we survey fish assemblages in six Mediterranean no-take reserves and their adjacent fishing grounds using environmental DNA (eDNA) while controlling for environmental conditions. We detect less fish species in marine reserves than in nearby fished areas. The paradoxical gradient in species richness is accompanied by a marked change in fish species composition under different managements. This dissimilarity is mainly driven by species that are often overlooked by classical visual... Tipo: Text Palavras-chave: Environmental DNA metabarcoding; Marine reserves; Alpha and beta diversity.
