title: Medicinal and ritualistic plants of the Kaiowá of Tekoha Taquara as a contribution to the demarcation of ancestral land, Mato Grosso do Sul, Brazil

description: Abstract Our research is with the indigenous Kaiowá, of the Tupi-Guarani linguistic trunk. Though the land the Kaiowá live on in the state of Mato Grosso do Sul (MS) underwent demarcation as an indigenous territory in 2010, named Tekoha Taquara, a document was issued by a Justice, suspending its validity. The Kaiowá therefore live vulnerably, occupying land that is not in their legal right. Kaiowá leaders challenged us to use their intricate knowledge of local flora as evidence for land rights. To highlight the specificity of their plant knowledge, our study operates on three assumptions: equal resources are available to indigenous and non-indigenous people and are valued distinctly; the Kaiowá have exclusive knowledge; traditional plants occur in the region. Guided tours were conducted with seven experts. Herbarium species, plant names in Guarani and Portuguese, uses and parts used were documented. The medicinal species from literature and from herbaria databases were compiled. Informant Consensus Factor (FIC) regarding uses was compared across articles and with Kaiowá knowledge. 659 medicinal species for MS were compiled. Of these, 61.8% are used exclusively in Taquara. The 90 registered species in our study make up the largest list among articles with indigenous people in MS. FIC demonstrated low similarity. Plant mixtures used by the Kaiowá is rarely mentioned in literature on medicinal plants. The Kaiowá cite species that no longer exist in the area. This supports that the specificity of Kaiowá knowledge, tying it to their land. Our results support the recognition of their ancestral land.

title: Climbing plants in rocky outcrops in Northeast Brazil: patterns of richness, floristic similarity and dispersion syndromes

description: Abstract Rocky outcrops are residual reliefs mountainous that occur in tropical, subtropical and temperate regions from all over the world. In this work, our objectives were to understand the richness patterns and floristic similarity of climbing plants, in rocky outcrops in Northeast Brazil, as well as to understand morphological aspects and dispersion forms of these species. The analyzes were carried out using a floristic list of climbing plants recorded in inventories of rocky outcrops, in the states of Paraíba and Pernambuco. We identified 143 species, 66 genera and 25 families. As for the morphological aspect, 72% of the species are herbaceous climbers and 28% are woody climbers (lianas). The most frequent ascending mechanism was the voluble (66%), and the most representative dispersion syndrome was autochory (44%). The richness of herbaceous and woody climbers was positively correlated with altitude, and negatively correlated with distance from the coast and temperature; negative correlation was also observed between richness of herbaceous climbers and precipitation, while for the woody the richness remained constant for this variable. The analysis of floristic similarity resulted in the formation of three groups, suggesting a floristic composition characteristic of the surrounding matrix, influenced by abiotic factors and vegetation types where rock outcrops are inserted.

title: Storage of seeds harvested from different positions of the floral scape to obtain imperial bromeliad plants - Alcantarea imperialis

description: Abstract Non-simultaneous dehiscence of bromeliads fruits should be considered for seed propagation purpose. The aim of this work was to evaluate the best method for the production of imperial bromeliad plants considering the simultaneous harvesting of the seeds of different positions of the floral scape in the period of base fruits dehiscence and its storage for later use in the production of plants. Seeds were harvested from the base, middle and top of the floral scape and stored for 26, 61, 154 and 213 days at 10 °C and 25 °C. Plants emergency were evaluated in gerbox with filter paper, and in vitro germination and growth with 10, 20 and 30 g.L-1 of sucrose. Seeds harvested from the base and stored for up to two months at 10 °C showed the highest percentage of plants emergence (57%). The best sucrose concentrations for in vitro germination was 10 g.L-1 and for plant growth 20 g.L-1. Considering the vulnerability of this bromeliad, the use of the seeds of all the floral scape can be a conservation strategy.

title: Cryopreservation of a threatened pindo palm species

description: Abstract Butia yatay is a palm tree native of Rio Grande do Sul that is in danger of extinction. Its propagation is carried out sexually, however, the seed germination is low, slow and uneven. Thus, a cryopreservation protocol was established aiming at the conservation of the species. Concentrations of sucrose were tested on embryo pre-treatment before freezing. Butia yatay embryos can be cryopreserved, with subsequent growth recovery, when they are submitted to previous treatment with 0.4 M sucrose. In this study, the embryos were frozen for 10 days, indicating that pretreatment allows the conservation of Butia yatay for a long time.

title: ThermoMechaLimestone

description: This data set gives nearly 5 years of temperature and displacements recorded on and in a limestone cliff. An extensive presentation of the monitoring device can be found in (Gasc-Barbier et al., 2020, 2015) and is summarized below. Interpretation of data is proposed in Gasc-Barbier et al. (submitted) Instrum.jpg display the hazard zone. We can see a perched cave in a limestone cliff where a part of its roof had collapsed. On its roof an unstable beam reminds. This remaining beam is delimited by a horizontal interlayer thinning from East to West, hanging to the roof of the cave at the west and east-clamped in the rock mass. Opened fractures can be observed all around the beam. In order to assess the remaining hazard, 4 fissurometers (F1 to F4) and a thermal probe were installed on the roof of the cave and two borehole extensometers (D1 and D2) were drilled perpendicular to the face of the cliff, above the cave, to understand the global behaviour of the rock mass. The four fissurometers were positioned around the remaining beam to quantify the aperture of the joints, in order to evaluate the relative movement of the blocks, according to changes in external conditions: F1 near the east-clamped end of the beam, and the three others on the west part: Two of them (F3 and F4) were fixed across a horizontal joint and a vertical joint respectively, F2 is positioned across the vertical joint in a 45° angle. The thermal probe was fixed on the roof of the cavity near the three. Fissurometers are LVDT strain gauges that measure displacements between their two extremes with a resolution of 1/10 th mm. DATA-Fissuromètres gives a record per hour. The borehole extensometers (D1 & D2) are RockTest / Télémac distofor@ anchored in the rock mass at the end of the borehole at a depth of 8 m from the cliff wall. Both were prepared with three displacement measuring points at depths of 2 m, 4 m and 6 m from the cliff wall and temperature measuring points at 2 m and 6 m depth. The supplier gives a measuring range of 100 mm, a resolution lower than 0.01 mm. Given the length of the rods used (8 m), the precision is about 0.05 mm. The operating temperature must remain between 0° and 50 °C. The devices were placed perpendicular to the rock face, about 4 m and 7.5 m above the roof of the cave cavity (see Gasc-Barbier et al. submitted). DATA_Extenso.xls gives a record per hour. Measurements lasts between July 2010 until April 2015. They were stopped when reinforcement works were proceeded in the cave in order to secure the village.

title: Flora of Brazil: Elaeocarpaceae

description: Abstract The major objective of this study was to contribute to the Flora of Brazil 2020, which is part of the targets established by the Conference of the Parties of the Convention’s signatory countries on Biological Diversity. The development of the Brazilian Flora is coordinated by the Rio de Janeiro Botanical Garden, under the direction of the Ministry of Environment of Brazil and involves national and international research institutions. In this work a floristic survey of the species of Elaeocarpaceae that occur in Brazil was made, as well as the elaboration of a flora for the family, with identification keys, descriptions of genera and species, taxonomic comments and geographical distribution. The main national herbaria were consulted and analyzed, either in person or through loans. The nomenclature types deposited in national and foreign herbaria were analyzed. Two genera were recognized: Crinodendron with one species and Sloanea with 43. Thus, 44 valid names, 57 synonyms and one new species for the family in Brazil were recognized. In addition, seven lectotypes, and 16 new synonyms were assigned.

title: Interactive key of arboreal species in seasonal forests of Southwest of Bahia

description: Abstract The seasonal forests are phytophysiognomies of the Atlantic Forest biology most threatened, mainly, by the pressure exerted by agribusiness pressure and the process urbanization process. In this scenario, the knowledge of its structure and, mainly, of its floristic composition, are fundamental for the processes of conservation and preservation of natural resources. In order to support the process of species identification, this work had as objective to make an interactive key of tree species located in seasonal forests of the Southwest of Bahia. In the making of the key were excluded the species with less importance and equal to one individual per hectare in the respective surveys. For the preparation of the dendrological key it was necessary a survey of the morphological characteristics of the leaf and the thin branche, taking into account its variations, as well it is presence or default. The data was released on the Xper3 online platform. The consistency of the database was analyzed through the tool “checkbase”. A total of 177 species were used, 62 of the Leguminosae family. The key is available on the Xper3 platform for free access, it is efficient and simple to use. The key contemplates any species in several surveys carried out in Bahia and, can also be used for Seasonal Forests in other States.

title: Ethnobotanical knowledge of Olinda’s historical site’s inhabitants, Natural and Cultural Heritage of Humanity

description: Abstract Olinda (Pernambuco, Brazil) has been declared Natural and Cultural Heritage of Humanity by UNESCO. Considering the ethnobotanical knowledge associated with the local population as an intangible part of this heritage, we evaluated the relation between knowledge richness of the inhabitants from the Olinda and useful plants diversity in their homes. The association of useful plant richness with the available green areas was verified, as well as inhabited periods and richness of knowledge. We interviewed 11 men and 37 women aged 18 or older living in 48 homes, in the Olinda's neighborhoods, 12 per neighborhood: Amparo, Bonsucesso and Carmo, in the historical site, as well as Ouro Preto, located in its outskirts. The total number of 346 species cited by the interviewees, 88% cultivated and 35%native, are used for landscaping (246spp), health care (81spp) and nourishment (80spp). No remarkable difference has been observed among the four neighborhoods; ornamental and medical applications were the predominant categories in use. The knowledge of inhabitants and available green area were the most influential factors for the sorting of plants in homes.

title: A botanical census on pyrrolizidine alkaloid-producing species in Brazilian herbaria: data set for a potential health risk indication

description: Abstract This study accessed the informational potential of herbaria collections as a tool for establishing an indication of the distribution of species that produce pyrrolizidine alkaloids (PAs), which are considered natural toxins, in Brazil. A total of 55,480 registered exsiccates were recorded, comprising species belonging to 17 genera, including Ipomoea (33.2%) (Convolvulaceae), Crotalaria (23.8%) (Fabaceae), Eupatorium (16.4%), Senecio (13.4%), Erechtites (3.97%) (Asteraceae) and Pleurothallis (8.28%) (Orchidaceae). These records were more densely distributed in the herbaria of the southeastern (30%), southern (28%) and northeastern (24%) Brazilian states. PAs are toxic to animals in general and display high potential for contamination of human food-production chains. A qualitative relationship was evidenced when carrying out a simultaneous compilation of cases of livestock intoxicated by the ingestion of these species, evidencing risks associated with PA-contaminated foodstuffs such as cereals, meats, milks and honey. The botanical census carried out herein is aimed at supporting a prospective study on the health risk presented by PA-producing species while bringing about indicators for their distribution in Brazil. This previously unpublished approach highlights the value of multidisciplinary information incorporated into herbaria botanical collections, with possible impacts on public health.

title: Soil seed bank and morphofunctional ecology of seedlings in remnants of Tropical Forest connected with agricultural matrix

description: Abstract The seed bank in the soil is one of the mechanisms of natural regeneration that contributes to the emergence of species in forest or degraded areas, however, the composition of species can be influenced by the history of land use, by the matrix in which the fragment is inserted, among others. The objective of this research was to evaluate the floristic composition, abundance and morphofunctional ecology of seedlings arboreal species found in the soil seed bank in tropical forest fragment. Soil samples were taken and taken to the forest nursery and covered by shading screens 70%. The emerged seedlings were counted, identified and classified in terms of dispersion syndrome, successional group and morphological and functional ecology of cotyledons. 3,441 seedlings emerged in 14 families and 28 morphospecies. Miconia prasina and Cecropia pachystachya predominated with 22.20 and 17.78%, respectively; zoochoric syndrome with 64%; there were predominance of early secondary species, followed by pioneers. 78% of the seedlings are of the PEF type (phanero-epigeal-foliaceous). Although the remnant is inserted in an agricultural matrix, it has an average tree species richness in the seed bank, most species being classified as phanero-epigeal-foliaceous, demonstrating the dynamics and self-regeneration capacity of the studied area.

title: Karyotypic analyses and genomic affinity among Argentinean species of Passiflora

description: Abstract The genus Passiflora (Passifloraceae) has more than 500 species, nineteen are native to Argentina. By their austral distribution, these species were included in breeding programs to obtain ornamental varieties tolerant to low temperatures. The aim of this work was to know the cytogenetic characteristics of Passiflora genotypes present in a working collection, as an indispensable knowledge for the development of a breeding plan. Chromosomal preparations were performed and karyotypic characteristics, rDNA sites by FISH and affinity among subgenera by GISH were studied. Chromosome counts in fourteen Argentinean species confirmed the basic chromosome numbers previously published: x = 6 for subgenus Decaloba, x = 9 for subgenus Passiflora and x = 10 for Dysosmia. The karyotypic parameters (karyotype, haploid chromosome length and asymmetry indices) and genomic affinities among the subgenera, clarify most of the chromosomal evolution of the genus. The results obtained strongly suggest that the basic number x = 6 would be the original one and that x = 9 was originated by processes of polyploidy and descendent dysploidy. Since subgenus Passiflora possesses the largest genomes, it is postulated that evolutionary process leading to x = 9 was accompanied by unequal distribution of non-coding repetitive DNA, mainly transposable elements. These processes could explain the asymmetrical karyotypes of species of subgenus Passiflora.

title: The importance of Serra do Mar State Park for liverworts conservation in the Atlantic Rainforest

description: Abstract Serra do Mar State Park (PESM) is located in southeastern São Paulo state, Brazil, and is the largest Atlantic Rainforest conservation area in the country. The park is divided into 10 nuclei, and the Itutinga-Pilões nucleus (NIP) was selected for study since no survey of liverworts species richness had yet been conducted there. The floristic similarities between the NIP and different areas of Atlantic Rainforest in São Paulo state were also assessed. One hundred and eighty liverworts species were identified in the three vegetation types (lowland, submontane, and montane ombrophilous forests) encountered in the NIP, distributed among 62 genera and 21 families. Lejeuneaceae showed the highest species richness with 80 species. The high number of epiphyllous species found in the study area (26% of all species) was notable. In terms of their worldwide distributions, 57% of the species are Neotropical. Clustering analysis showed that the areas of the PESM and Jureia-Itatins Ecological Station were grouped together with the highest similarity values. The liverworts flora of the NIP demonstrates the importance of that nucleus for the conservation of liverworts diversity in the Atlantic Rainforest of the São Paulo state, as well as in Brazil.

title: Estimation of leaf area of Mesosphaerum suaveolens from allometric relations

description: Abstract The determination of leaf area is of fundamental importance in ecophysiological studies that seek to understand the plant-environment relationship. The objective of this research was to determine an allometric equation to estimate the leaf area of Mesosphaerum suaveolens from linear measures of leaf blade (length and/or width). There were collected 900 random leaf limbs of different shapes and sizes, in an anthropic area of caatinga, located in the municipality of Santa Luzia, state of Paraíba, Northeast of Brazil. For the construction of the allometric equations the following regression models were used: linear, linear without intercept, quadratic, cubic, power, and exponential. The linear model without intercept using the product between length and width (C.L) was the most recommended to estimate the leaf area of M. suaveolens, with greater coefficient of determination (R2) and Willmott concordance index (d), lesser mean absolute error (MAE), Akaike information criterion (AIC) and root-mean-square error (RQME), and the closer the BIAS ratio is to zero (R2 = 0.9971; d = 0.9989; MAE = 0.422; AIC = 2094.69; RQME = 0.770; BIAS = -0.0105). The leaf area of M. suaveolens can be estimated satisfactorily by equation AF = 0.6787*(C.L).
