Mangrove Soils

Smectitic clay minerals are frequently identified in mangrove soils, but there is little information about their types and origins. Besides their importance in the agronomical and geotechnical areas, smectites play an important environmental role by adsorbing nutrients, organic pollutants and heavy metals. Smectites found in mangrove soils can be of marine or continental detrital origin, or of neoformation origin. Thus, the objective of this study was to identify the types of smectites present in the State of São Paulo mangrove soils (Brazil), and to relate them to their possible origins. Soil samples were taken in five mangroves along the State of Sao Paulo State coast line. The mineral composition of the clay fraction was identified by X-ray Diffractometry (XRD) applying the Greene-Kelly test and by Fourier transform infrared spectroscopy (FTIR). Highlighting the peaks in the 3,560 cm-1 band and in the region near 798 and 820 cm-1, there was a predominance of nontronite in the soil at the Sítio Grande River, Pai Matos Island, Caranguejo Island and Itapanhaú River mangroves, and possibly a lower concentration of ferric montmorillonite in the Escuro River mangrove. Since the continental sediments in these environments are very poor in smectite, the origin of these minerals in the mangrove soils studied is related to sedimentation left by past marine transgressions, to neoformation processes, or yet to a combination of both origins.

The State of São Paulo is one of the most studied regions of Brazil in regard to amphibian species richness and distribution. However, we still do not have a list of species for the State. Therefore, we present here a list including 231 species of amphibians (225 anurans and six caecilians), of which 27 are endemic. We present data about previous and current taxonomists and speculate about future prospects in the study and conservation of amphibian biodiversity in São Paulo State.

Esterase Phenotypes

Teak (Tectona grandis Linn. F.) is one of the most important forest crops in Brazil, occupying areas in different regions, such as Goiás, Mato Grosso, Paraná, and São Paulo states. Teak wood is used for many purposes such as shipbuilding, rolling and plywood, firewood, and charcoal. In May 2011, teak symptomatic feeder root samples, exhibiting inconspicuous, small galls, were collected in the municipality of Piracicaba, São Paulo State, Brazil (22°41′46.90″S, 47°38′36.84″W). Specimens were identified through perineal patterns and esterase phenotypes of 20 adult females (1,2). Perineal patterns and esterase phenotypes were consistent with those described for Meloidogyne arenaria (Neal, 1889) Chitwood, 1949 and M. javanica (Treub, 1885) Chitwood, 1949. Perineal patterns of M. arenaria showed a low dorsal arch, compressed dorsolaterally, with lateral field marked by some forked and broken striae; no punctate markings between anus and tail terminus were observed. Perineal patterns of M. javanica were rounded, with low dorsal arch, striae smooth, lateral field distinct, clearly demarcated from striae by parallel lines. From the esterase electrophoresis we obtained A2 (Rm:1.2;1.3) and J3 (Rm:1.0;1.25;1.4) phenotypes, typical from M. arenaria and M. javanica, respectively. To our knowledge, this is the first report of M. arenaria parasitizing teak roots in Brazil and elsewhere (new host) and the first report of M. javanica infecting teak in the State of São Paulo. Previously, M. javanica was reported to be infecting teak-growing areas in the State of Mato Grosso (3). This finding has a great importance, not only by the inclusion of these parasites in teak pathological scenario, but also for predicting possible damage in plant species used in teak-based intercropping systems.

Substantial Heterogeneity

AbstractSão Paulo (SP), a densely inhabited state in southeast Brazil that contains the fourth most populated city in the world, recently experienced its largest yellow fever virus (YFV) outbreak in decades. YFV does not normally circulate extensively in SP, so most people were unvaccinated when the outbreak began. Surveillance in non-human primates (NHPs) is important for determining the magnitude and geographic extent of an epizootic, thereby helping to evaluate the risk of YFV spillover to humans. Data from infected NHPs can give more accurate insights into YFV spread than when using data from human cases alone. To contextualise human cases, identify epizootic foci and uncover the rate and direction of YFV spread in SP, we generated and analysed virus genomic data and epizootic case data from NHP in SP. We report the occurrence of three spatiotemporally distinct phases of the outbreak in SP prior to February 2018. We generated 51 new virus genomes from YFV positive cases identified in 23 different municipalities in SP, mostly sampled from non-human primates between October 2016 and January 2018. Although we observe substantial heterogeneity in lineage dispersal velocities between phylogenetic branches, continuous phylogeographic analyses of generated YFV genomes suggest that YFV lineages spread in São Paulo state at a mean rate of approximately 1km per day during all phases of the outbreak. Viral lineages from the first epizootic phase in northern São Paulo subsequently dispersed towards the south of the state to cause the second and third epizootic phases there. This alters our understanding of how YFV was introduced into the densely populated south of SP state. Our results shed light on the sylvatic transmission of yellow fever in highly fragmented forested regions in SP state and highlight the importance of continued surveillance of zoonotic pathogens in sentinel species.Author’s SummarySince July 2016, the southeast region of Brazil has experienced the largest yellow fever virus (YFV) outbreak in decades. São Paulo is the most densely populated state in southeast Brazil. The outbreak has caused serious public health concern in the state, as YFV does not normally circulate widely there and most of the 21 million inhabitants were correspondingly unvaccinated against YFV when the outbreak began. In Brazil, YFV typically circulates among non-human primates, and human cases represent isolated spillover events from this predominantly sylvatic cycle. Understanding the epidemiological dynamics and spread of YFV in non-human primates is therefore critical for contextualising human cases, and guiding vaccination strategies that can better protect local human populations. Here, we aim to contextualise human cases, identify epizootic foci and uncover the rate and direction of YFV spread in SP. We analyse the geographic and temporal distribution of observed cases of YFV in non-human primates in São Paulo state, and identify three distinct phases of the epizootic. We generate sequence data from 51 YFV-positive cases and perform phylogenetic and phylogeographic analyses aimed at understanding the spatial spread of YFV in São Paulo state. Analyses of these data indicate that YFV spread from the north of São Paulo state into more densely populated southern regions. Although we observe substantial heterogeneity in the rate at which different sampled YFV lineages spread, the typical rate of spread was low with a mean rate of ~1 km per day. This is consistent with a scenario in which the majority of transmission events occurred between non-human primates and sylvatic vectors across forested patches.Article Summary LineGenomic surveillance of yellow fever in São Paulo during the 2016-2018 epizootic

The aim of this work is clarify the identification of Mesocyclops ogunnus that occur in several reservoirs in the State of São Paulo and that was previously identified as Mesocyclops kieferi. These two species are closely related species with very similar characteristics. The differential characteristics are presented and the distribution of both species in the world is discussed.
