Contrasting effects of host identity, plant community, and local species pool on the composition and colonization levels of arbuscular mycorrhizal fungal community in a temperate grassland
(Blackwell Publishing LTD, 2020)Arbuscular mycorrhizal fungi (AMFs) are important plant symbionts, but we know little about the effects of plant taxonomic identity or functional group on the AMF community composition. To examine the effects of the ... -
DESCRIPTION OF TWO NEW SPECIES OF Crenicichla (TELEOSTEI: CICHLIDAE) FROM THE LOWER IGUAZÚ RIVER WITH A TAXONOMIC REAPPRAISAL OF C. iguassuensis, C. tesay AND C. yaha
