In Brazil, some mangrove areas are subjected to air pollution by particulate iron from mining activities. However, the effect of this pollutant on mangrove plants is not well known. This study aimed to comparatively analyze the morphoanatomy, histochemistry, and iron accumulation in leaves of Avicennia schaueriana, Laguncularia racemosa, and Rhizophora mangle. Samples were collected from five mangrove sites of Espírito Santo state, each of which is exposed to different levels of particulate iron pollution. The amount of particulate material settled on the leaf surface was greater in A. schaueriana and L. racemosa, which contain salt glands. High iron concentrations were found in leaves of this species, collected from mangrove areas with high particulate iron pollution, which suggests the foliar absorption of this element. None of the samples from any of the sites showed morphological or structural damage on the leaves. Scanning electron microscopy (SEM) coupled to X-ray diffraction rendered a good method for evaluating iron on leaves surfaces. A histochemical test using Prussian blue showed to be an appropriate method to detect iron in plant tissue, however, proved to be an unsuitable method for the assessment of the iron bioaccumulation in leaves of A. schaueriana and R. mangle. So far, this study demonstrates the need of evaluating the pathway used by plants exposed to contaminated particulate matter to uptake atmospheric pollutants. © 2015 Elsevier Ltd.

We report geographic range extensions for two anuran species, Brachycephalus didactylus (Bachycephalidae) and Zachaenus parvulus (Cycloramphidae), recorded during a short-term herpetofaunal survey carried out at mid-elevation (600-900 m) Atlantic Forest sites at the Serra das Torres mountains (21°00' S, 41°13' W), in the state of Espírito Santo, SE Brazil. These two species are reported for the first time in Espírito Santo, representing the northernmost records for both of them and raising to 135 the number of anuran species currently known to occur in the state. © 2012 Check List and Authors.

The goal of this study was to contribute to the knowledge of the mammals in the state of Espírito Santo, presenting a list to the Domingos Martins municipality. Regarding the mammals inventory, data obtained from field work and through digital search by species deposited in scientific collections and available on the SpeciesLink database were used. We recorded 47 non-volant mammal species, including 12 endemic in the Atlantic Forest and nine listed as threatened. Domingos Martins, despite being undersampled when compared to other mammals inventories in the state of Espírito Santo, represents 57% of the terrestrial mammals listed in the state. This shows the potential of the municipality in relation to mammal conservation, not only in the state, but also for Atlantic Forest biome. © 2014 Check List and Authors.
