“…Both studies identified Clethra mexicana, Liquidambar styraciflua, Quercus germana and Quercus xalapensis as dominant species in the HMFs of the central region of Veracruz. However, in our study Lippia myriocephala had higher structural values, which indicates that it is a secondary forest, which has been formerly subject to disturbances (González-Zamora et al, 2016).…”

Tree structure and diversity at the protected natural area La Martinica, Veracruz, México. Introduction: The Humid Mountain Forest (HMF) has the largest number of plants per unit area, which vegetation grows in heterogeneous environmental conditions and has a high variation flora, physiognomy and structural. The conservation of the HMF is important due to the biodiversity it harbors and the environmental regulation services it provides. Objective: This work evaluated the effect of the direction of sun exposure (aspect) of the terrain and the density of the forest canopy (canopy opening type) on the structure and tree diversity in La Martinica Protected Natural Area, in Veracruz, Mexico. Methods: stratified sampling was performed in four aspects of the terrain and two canopy density conditions. In total, 25 20 x 25 m sampling units were considered (subdivided into 10 x 5 m units), in which the normal diameter (ND), total height and the largest and smallest diameters of the crown of the individuals with a ND ≥10 cm were registered. The diversity was estimated by means of rarefaction curves and the structure was analyzed through the importance value index and the forest value index. Results: We recorded 37 species belonging to 30 genera and 24 families, Zenithal and South aspects had the highest floristic similarity. Greater diversity was observed in the North aspect and in the Closed canopy. The tree species with the highest structural values were different between aspects and canopy types; Carpinus tropicalis presented the highest values in the Zenithal aspect, Lippia myriocephala in the East and South aspects, and Liquidambar styraciflua in the North. In both types of canopy Lippia myriocephala obtained the highest values in the Importance Value Index (IVI) and only Forest Value Index (FVI) in the Open canopy; Carpinus tropicalis reached a higher FVI in the Closed canopy. Conclusions: The tree structure was different in the four aspects studied, as well as in the two conditions of the canopy. The greatest difference in species composition and diversity was observed between the North and East aspects, of these, the North presented the highest richness values, equally frequent species and dominant species.

“…Similarly, the crop type clearly affected the composition of MDC bacterial microbiome, as revealed by NMDS and PERMANOVA. Coffee samples came from perennial plantations, grown under agroforestry systems, holding several tree shade species and with minor use of fertilizers and pesticides (Gordon et al, 2007;González-Zamora et al, 2016). Moreover, tillage is not employed, leading to the establishment of many soil microbiota species (Legrand et al, 2018;Dube et al, 2019).…”

The Bacterial Microbiome of Meloidogyne-Based Disease Complex in Coffee and Tomato

et al. 2020

The Meloidogyne-based disease complexes (MDCs) are caused by the interaction of different root-knot nematode species and phytopathogenic fungi. These complexes are devastating several important crops worldwide including tomato and coffee. Despite their relevance, little is known about the role of the bacterial communities in the MDCs. In this study 16s rDNA gene sequencing was used to analyze the bacterial microbiome associated with healthy and infested roots, as well with females and eggs of Meloidogyne enterolobii and M. paranaensis, the causal agents of MDC in tomato and coffee, respectively. Each MDC pathosystems displayed a specific taxonomic diversity and relative abundances constituting a very complex system. The main bacterial drivers of the MDC infection process were identified for both crops at order level. While corky-root coffee samples presented an enrichment of Bacillales and Burkholderiales, the corckyroot tomato samples presented an enrichment on Saprospirales, Chthoniobacterales, Alteromonadales, and Xanthomonadales. At genus level, Nocardia was common to both systems, and it could be related to the development of tumor symptoms by altering both nematode and plant systems. Furthermore, we predicted the healthy metabolic profile of the roots microbiome and a shift that may result in an increment of activity of central metabolism and the presence of pathogenic genes in both crops.

“…A su vez, varias de estas especies complementan su dieta con frutos y dispersan sus semillas, contribuyendo a la restauración pasiva de estos bosques tropicales húmedos (Hernández-Ladrón de Guevara et al, 2012). Adicionalmente, los bosques tropicales húmedos y semihúmedos del área de estudio están en su mayoría asociados a cafetales, por lo que mantienen condiciones estructurales y de composición similares a la de bosques primarios (Alvarez-Alvarez et al, 2020;González-Zamora et al, 2016). Esto ha permitido la presencia mayoritaria de ciertos grupos de insectívoros dependientes del sotobosque (e.g., Basileuterus belli, Dromococcyx phasianellus, Henicorhina leucophrys, Thryophilus pleurostictus) y una disminución de omnívoros y granívoros (e.g., Calocitta formosa, Columbina inca, Pitangus sulphuratus, Sporophila torqueola) que generalmente se favorecen de las modificaciones a la vegetación natural (Tejeda-Cruz y Gordon, 2008; Tejeda-Cruz y Sutherland, 2004).…”
