Diferentes terminologias para as sequências de solo (pedossequência) são adotadas considerando o fator genético predominante, como: litossequência (material de origem) (Campos et al., 2007; Motta et al., 2002); topossequência (relevo) (Bushnell, 1942; Curi & Franzmeier, 1983); climos- sequência (clima) (Bracewell et al., 1976, Rabenhorstet al., evolutivo das catenas. Este trabalho tem como objetivo descrever uma pedossequência na SerradaCanastra, caracterizada por uma polaridade inversa da gibbsita e razões de Fe d /Fe 2 O 3 eFe o /Fe d próprias de um ambiente redutor. A pedossequência possui Latossolo no topo e Gleissolo na base. Entre a alta e média vertentes ocorrem solos desenvolvidos in situ, com uma sequência apresentando Latossolo a montante e Cambissolo a jusante. Na baixa vertente, ocorrem solos desenvolvidos sobre rampas de colúvio, mostrando a sequência Latossolo- Gleissolo para jusante. Foram coletadas amostras dos horizontes diagnósticos em 10 trincheiras ao longo de uma pedossequência. As amostras foram submetidas às seguintes análises: ferro extraído com ditionito-citrato-bicarbonato (Fe d ) e oxalato de amônio (Fe o ), análise termogravimétrica para quantifi cação direta de gibbsita e caulinita e susceptibilidade magnética. O conjunto de dados foi processado por análise multivariada: Análise de Componentes Principais (ACP) e Análise de Grupos (AG). Observou-se que os solos mostram uma evolução lateral de transformação de Latossolos em Gleissolos, de forma progressiva e descontinuada na paisagem. O limite superior da vertente onde ocorrem depósitos coluvionares é marcado pela variação da susceptibilidade magnética, textura e cor do solo. As análises multivariadas (ACP e AG) e os estudos de campo indicam que a pedossequência é derivada de sucessivos solapamentos provocados por erosão subsuperfi cial e deposição de colúvio, com avanço de ambientes hidromórfi cos nestas porções relativamente rebaixadas da paisagem.
The dominant vegetation of SerradaCanastra National Park is cerrado sensu lato, but more than 90% of its total area is covered by subdivisions of this formation, known as campo limpo and campo sujo; the park has small portions of campo rupestre, and cerrado sensu stricto, and patches of gallery forest with Atlantic forest characteristics 8 . The relief is undulating, with streams in the valleys. The climate has a marked seasonality,
The Conservation Units (CU) were created to protect natural environments from growing degra- dation and to impede the expansion of urbanization and agricultural crops. The SerradaCanastra National Park, established to protect the headwaters of the São Francisco River and other places of scenic and ecological interest, is extensively visited due to its many tourist attractions, such as waterfalls, fauna and flora. An analysis of the park’s geography is needed to assess the risk in- volved in and its suitability for public use due to its territorial extension and environmental com- plexities. Thus, this study aimed to investigate the background of issues of interest to CU man- agement. Additionally, we used high-resolution RapidEye imagery, altimetry and database of park infrastructure to build geospatial database and estimate classes of suitability for and risk in public use through GIS tools. The resulting cartographic data can support the planning of policies con- cerning the landscape and park’s territorial management.
We collected the specimens in SerradaCanastra in the Delfino´polis municipality, Minas Gerais, Brazil. The individuals were pressed for dry vouchers and then fixed in a FAA70 (Formaldehyde-Glacial Acetic Acid-Ethyl Alcohol 70%) solution for the morphological analy- ses, which were performed using a stereomicroscope and light microscope. In addition, some specimens were fixed in a mixture of 5% glutaraldehyde with 2.5% formaldehyde in a 0.006-M cacodylate buffer (pH 7.2) and the morphological analyses were performed using a scanning electron microscope (SEM). For the SEM, the fixed material was dehydrated, subjected to criti- cal drying point using liquid CO 2 , and sputter-coated with gold and digital photos of the ana-
Canastra cheese is a cheese with geographical indication recognized by the Brazilian National Institute of Indus- trial Protection under number IG201002. It is produced in seven municipalities in the state of Minas Gerais in a region called SerradaCanastra. In this work, samples of milk, “pingo” (natural starter), whey and Canastra cheese were collected on a farm in Medeiros-MG/Brazil to evaluate the yeast microbiota and select yeasts for whey fer- mentation to produce ethanol and volatile aromatic compounds of relevance in the production of cheese. Thirty- nine isolates capable of fermenting lactose in a synthetic medium were identiﬁed by MALDI-TOF as Kluyveromyces lactis (29), Torulaspora delbrueckii (7) and Candida intermedia (3). Eleven isolates of K. lactis and three of T. delbrueckii ef ﬁciently fermented lactose until 4th day, and due to this reason were selected for cheese whey fermentation with Brix 12, 14 and 18. Generally, the isolates T. delbrueckii B14, B35, and B20 and K. lactis B10 were the most effective regardless of the initial Brix value. The identiﬁcation of these four isolates by MALDI TOF was con ﬁrmed by sequencing of the ITS region. In the fermentation of cheese whey 14 Brix, T. delbrueckii B14 and B35, respectively yielded 24.06 g/L and 16.45 g/L of ethanol, while K. lactis B10 was more ef- ﬁcient in the consumption of lactose. In sequential culture with K. lactis B10 inoculated 48 h after T. delbrueckii B14, 97.82% of the total sugars were consumed resulting in the production of 19.81 g/L ethanol and 39 aromatic volatile compounds. The most abundant compounds were 3-methyl-1-butanol, octanoic acid and ethyl decanoate, which are reported as important for the aroma and ﬂavor of cheeses. Based in our results, B10 isolate inoculated 48 h after B14 isolate is a promising yeast inoculum to be used for fermentation of dairy substrates.
As to the interpretation of the breccias properly, it is provisionally envisaged that they are of the hydrothermal phreatic eruptive type, connected to hot spring activity, with heat probably originating from an igneous source at depth, or even from the rift tectonic setting itself, involving only meteoric and connate, non-magmatic waters (Nelson and Giles 1985; Sillitoe 1985; Hedenquist and Henley 1985; Laznicka 1988, 1989; Lawless and White 1990). In the case of Serrada Borda, the specific igneous heat sources at depth, as well as eruptive centers, remain undefined. This notwithstanding, the process can explain the strata-bound morphology of the breccia bodies and its association with massive to banded metachert, in part exhibiting elongated vugs and cavities following banding that have been considered a typical feature of sinters (e.g., Sillitoe 1993) (Fig. 5B, C, D). Globular textures (Fig. 5E) have also been reported from sinters (Nelson and Giles 1985). Moreover, chaotic breccias (Fig. 4G) also occur in this kind of hydrothermal environment, originating from sinter plates broken and deposited by collapse in the bottom of water bodies (e.g., in the San Quentin sinter of McLaughlin, California; Laznicka 1988; University of California 2007).
The first bryophyte record for Serra de Sintra region dates back to the very beginning of the 19 th century and is due to Brotero (1804), who reported it in his Flora Lusitanica. It was followed, in the next decades of the century, by those of Schimper (1836-1851, 1876), Mitten (1853), Levier (1880), Bottini (1886), Henriques (1886, 1889) and Warnstorf (1899). Both Mitten and Schimper identified material collected by Welwitsch between 1839 and 1853. Since the beginning of 20 th century and up to 1950 several contributions to Sintra bryoflora were based on explorations by important bryologists such as Luisier (1907, 1910a, 1910b, 1916), Dixon (1912), Nicholson (1913), Machado (1917, 1920, 1925, 1928, 1930, 1932), Mendes (1948), Pereira Coutinho (1917a, 1917b), Casares Gil (1919, 1932), Allorge (1931a, 1931b, 1931c, 1935), Buch (1937), Ade & Koppe (1942), Sabino de Freitas (1944, 1948), Potier de la Varde (1945), as well as Portuguese botanists such as Tavares & Tavares (1946, 1948), Mendes (1948) and Sá Nogueira (1950). The latter’s collections are reported in her publication “Briófitos daSerra de Sintra”, in which she organized the records of the specimens gathered and previously referred under the name of Barros (1942a, 1942b, 1943).
A avaliação da dinâmica do carbono como indicador de serviços ecossistêmicos de regulação climática, através da modelagem de diferentes cenários sobre mudanças de uso e cobertura do solo (LULC), é amplamente utilizada em estudos de conservação ambiental para apoiar processos decisórios atrelados a políticas públicas. Todavia, são raros os estudos em escala local que analisam a relação de impacto e custo-benefício da simulação de cenários agrícolas sustentáveis na prestação de serviços ecossistêmicos. Neste trabalho, realizamos a quantificação, a avaliação econômica e o mapeamento da captura e do estoque de carbono de cenários LULC passados (2007- 2017) e futuros (2027), em uma fazenda pecuarista daSerrada Mantiqueira, para entender como diferentes mudanças de paisagens podem impactar o serviço de regulação climática e contribuir economicamente com o setor agrícola. Sob uma abordagem SIG, empregamos técnicas de detecção remota, para elaborar os mapas LULC, ferramentas de modelagem Integrated Valuation of Ecosystem Services and
Sampling and data analysis
Sampling was carried out between November 2014 and March 2016. We perform fixed point observation, where birds were identified by visual and vocalization contacts, using 8x42 binoculars and literature consults (Sick, 1997). Five sampling points were distributed on the margins of forest fragments in the Serra de Itabaiana with favorable conditions for the detection of birds of prey (Figure 1). Observations were made from 06:00 AM to 12:00 PM in each point; visits were drawn at random, in a way that all points were visited once per month. In addition, we also made observations on a pre-existing trail of approximately 3 km, located within PARNASI, in order to obtain a better representation of the phytophysiognomic variations present in the area and to register the species that usually occupy the interior of these environments. Observations on the trail were also made once a month, from 06:00 AM to 12:00 PM.

Although the predictive classi ﬁcation performance regarding the cheese producer identi ﬁcation, achieved using the free amino acids data were better compared with that previously reported by Reis Lima, Bahri, et al. (2019) using the cheeses’ fatty acids proﬁles, the former was slightly less well succeeded when trying to predict the production date (sensitivity of 67% for LOO-CV procedure, data not shown), showing that the free amino acids contents were more inﬂuenced by the dairy industry speci ﬁcations (composition of the raw milk used and the speciﬁc and diﬀerent technological singularities used by each producer) than the production date. On the other hand, if the individual free amino acids contents were used instead of the related protein ratios, the LDA-SA models established possessed a lower predictive discrimination capability, leading to only 92% of correct cheese classiﬁcation by producer (LOO-CV, data not shown). This ﬁnding may indicate that the use of the protein ratios, an indirect normalization procedure of the free amino acids levels (taking into account the total protein content of each cheese), could enhance their discrimination power. Nevertheless, the results obtained in the present work clearly demonstrate that the free amino acids (namely the global free levels) and their related protein ratios could be used as preliminary potential discriminative variables for assessing Serrada Estrela cheese producer and so guaranteeing the cheeses origin. Still, cheese is a high complex food matrix, conse- quently, the establishment of a cheese traceability system would re- quire inclusion of other cheese metabolites in a global composition data fusion chemometric strategy.
Data reported on cheeses' moisture, total fat, total protein and salt contents were experimentally obtained by NIR spectrophotometry. Data on cheeses' free amino acids pro ﬁles were determined using UPLC-DAD-MS/MS chromatography.

Boxplots for essential free amino acids contents raw data (histidine, leucine-isoleucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine, in mg/100 g of cheese wet basis) of 24 Serrada Estrela PDO cheeses (2 independent samples per cheese) determined by UPLC-DAD-MS/MS (triplicate assays), according to the certiﬁed cheese producer (Producers 1 to 6). Dairy farms were located in 5 municipalities (Celorico da Beira e CB, Gouveia e G, Nelas e N, Oliveira do Hospital e OH, and Penalva do Castelo - PC) within the PDO geographical region and the chesses were produced between November 2017 and March 2018, being acquired after 45 days of maturation (values calculated using the data provided in the supplementary material ﬁle Table_S3_DIB-D- 19-02387.xlsx ).
Spizaetus melanoleucus . A presença de Suiriri islerorum apenas na EESGT provavelmente se deve ao fato de que até a sua descrição por Zimmer et al. (2001) essa espécie era confundida com S. s. affinis.
Somando-se as listas disponíveis para o PEJ (Pacheco & Silva 2002, Leite & Lopes 2002, Braz 2003, Tocantins 2003), para a APATM (Santos 2001) e a do presente trabalho, chega-se a um total de 366 espécies para a região daSerra Geral e áreas adjacentes, na região do Jalapão, nas fronteiras dos Estados do Tocantins, Maranhão, Bahia e Piauí (Apêndice), o que corresponde a 42% da avifauna já registrada no Bioma Cerrado segundo Silva (1995b) e Silva & Santos (2005). Entretanto, na APATM foram registradas 46 espécies que não foram observadas nas outras duas áreas. Algumas destas, como Penelope jacucaca e Picumnus pygmaeus, demonstram maior influência da fauna da Caatinga em parte da APATM, enquanto outras como Rostrhamus sociabilis, Aramus guarauna e
