The microbial community in a recirculating aquaculture system (RAS) is pivotal in fish health, contributing significantly to the productive performance during the growing-out phase. Classical and molecular methods using PCR for species-specific amplifications have traditionally been used for bacterial community surveillance. Unfortunately, these approaches mask the real bacterial diversity and abundance, population dynamics, a...
Floristic and Structural Heterogeneity in a Neotropical Riparian Wetland: Conservation ImplicationsNARA Subscribed
Despite the incontrovertible importance of wetland ecosystems, our understanding of the causes underlying the spatial heterogeneity of their attributes is still insufficient. Here, we assess the spatial variation of the floristics (species composition and their relative abundances) and quantitative structure (vegetation cover) of the San Pedro Mártir River riparian herbaceous wetlands (Tabasco, Mexico), and explore potential f...
Background Senescence is a cellular aging-related process triggered by different stresses and characterized by the secretion of various inflammatory factors referred to as senescence-associated secretory phenotype (SASP), some of which are produced by the NLRP3 inflammasome. Here, we present evidence that the NLRP1 inflammasome is a DNA damage sensor and a key mediator of senescence. Methods Senescence was induced in fibroblas...
Geography and ecology shape the phylogenetic composition of Amazonian tree communitiesNARA Subscribed
Aim Amazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types. Location Amazonia. Taxon A...
Geographic patterns of tree dispersal modes in Amazonia and their ecological correlatesNARA Subscribed
Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser‐availability hypothesis) and/or the availability of resources for constructing zoocho...
NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the NeotropicsNARA Subscribed
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos,...
Genetically engineered Pseudomonas : a factory of new bioplastics with broad applicationsNARA Subscribed
Summary New bioplastics containing aromatic or mixtures of aliphatic and aromatic monomers have been obtained using genetically engineered strains of Pseudomonas putida . The mutation (–) or deletion (Δ) of some of the genes involved in the β‐oxidation pathway ( fad A − , fad B − Δ fad A or Δ fad BA mutants) elicits a strong intracellular accumulation of unusual homo‐ or co‐polymers that dramatically alter the morphology of th...
