Abstract The riparian forest sustains an expressive richness and diversity of species and anthropogenic impacts in certain sites have caused changes in the structure of the communities. This study aimed to analyze the composition and structural parameters of the lichen community in riparian forests. The study was carried out in seven sites surrounded by different matrices: rural, urban and industrial. The lichens were mapped using the acetate method and the composition and phytosociological parameters were analyzed. A total of 208 species were identified. The riparian forest sites of the rural matrix differed from the others by the dominance of the morphological forms crustose and squamulose, as well as the predominance of species from humid and shaded environments. Phyllopsora lividocarpa, Phyllopsora parvifolia and Herpothallon minimum presented the highest importance values in the forest sites. The lichen community presented greater homogeneity in riparian forest sites of the urban-industrial matrix. Modifications in the species’ composition and structural parameters of the lichen community demonstrated a gradient of disturbances in the different matrices. Preservation actions of riparian forests are essential for the conservation of the species and landscape connectivity since they act as an important reservoir of biodiversity in sites of subtropical watersheds.

Abstract Extraradical spores of arbuscular mycorrhizal (AM) fungi are often parasitized by a wide range of soil microorganisms. However, reports on the parasitization of intraradical structures of AM fungi are very rare. While examining AM colonization in roots of Cuminum cyminum and Sambucus nigra growing in the medicinal plants garden of the Centre of Medicinal Plants Research in Homeopathy of the Nilgiris, we found that AM fungal hyphal coils, arbusculate coils, vesicles, and intraradical spores are colonized by dark septate endophytic (DSE) fungi which were co-occurring with AM fungi. The AM fungal hyphae were significantly wider than the DSE fungi. Colonization of different AM fungal structures significantly varied between the two plant species. Moreover, the percentage of colonized AM fungal structures was linearly correlated to the abundance of these structures. The colonization of the intraradical structures of AM fungi is illustrated and the significance of this phenomenon needs further elucidation.

Abstract We investigated the associations of seasonality, dispersal modes and seed germination speeds with the fruiting of Clusia nemorosa, Pleroma fissinervium, and Vochysia pyramidalis in a gallery forest, Chapada Diamantina, Brazil. Observations of mature fruits with dispersing seeds were carried out from 2003 to 2006. Cross-correlation and circular statistics were performed to test the relationships among fruiting and abiotic factors, and phenological seasonality. Dispersion syndromes were defined and germination experiments were performed after seed collection (n =100/species), using four replicates. The species evidenced seasonal fruiting. Clusia nemorosa produced zoochoric seeds and V. pyramidalis anemochoric seeds, which were dispersed during the rainy season and positively correlated with precipitation; P. fissinervium produced autochoric seeds, released during the dry season to early rainy season, being positively correlated with insolation and negatively with humidity. The rotating wing seeds of V. pyramidalis were released in the rainy season and aided floating in watercourses, characterizing hydrochory. Clusia nemorosa and V. pyramidalis germinated (2-6 days) more rapidly than P. fissinervium (9 days). Seasonality, dispersal modes, and optimal germination conditions modulated the fruiting of the species examined, whose reproductive strategies responded to environmental drivers such as precipitation, favoring germination during the rainy season.

Abstract The objective of the study was to identify the most suitable substrate and type of cutting to obtain seedlings from Baccharis vulneraria Baker cuttings. Apical and stem cuttings were collected from stock plants grown in a greenhouse. After collection, the cuttings were grown in the following substrates: commercial peat-based substrate (CPS); Vermiculite (VM); carbonized rice husk (CRH); Coconut fiber (CF); VM and CRH (1:1) (VM + CRH); VM and CF (1:1) (VM + CF); and CRH and CF (1:1) (CRH + CF) mixtures. The experiment used a completely randomized factorial design and, after 60 days, the percentage of survival and rooting (% SR), aerial part length (APL) and roots length (RSL), number of shoots (SN) and new leaves (LN), root volume (RSV), aerial part dry mass (APDM), and roots dry mass (RSDM) were evaluated. An interaction was found between the type of substrate and cutting for APL, RSL, LN, RSV, and RSM. On the other hand, %SR, SN and APDM differed only by cutting type. Apical cuttings showed higher APL, while internode cuttings showed higher SN, LN, RSV, and APDM. CPS promoted higher RSL in both types of cuttings, being a suitable option for the propagation of Baccharis vulneraria, particularly in internode cuttings.

Abstract Verbenaceae includes 32 genera and approximately 800 species distributed mainly in the Neotropical region, especially diversified in Brazil, where the campo rupestre stands out as an important vegetation type for the family. The Itacolomi State Park (ISP) is located in the southeast of the Quadrilátero Ferrífero, Minas Gerais state (MG), Brazil. Vegetation at the Park is composed of campo rupestre and forest remnants among degraded areas. The present research provides a floristic treatment of Verbenaceae in this protected area. Data were obtained from fieldwork and herbarium study. A total of 13 species were recorded: Glandularia phlogiflora, Lantana camara, Lantan fucata, Lantana tiliaefolia, Lantana trifolia, Lippia brasiliensis, Lippia hermannioides, Lippia origanoides, Petrea volubilis, Stachytarpheta cayennensis, Stachytarpheta commutata, Verbena litoralis and Verbena rigida. Among them, six are new records for the ISP. Stachytarpheta glabra, endemic to MG, was found in an area of canga very close to the boundaries of the Park. Additionally, S. viscidula, whose type locality is close to the Park, is proposed as a new synonym for S. commutata, whose type specimen comes from the Park. We provide an identification key, descriptions, photographs and comments on taxonomy, ecology and distribution for each species.

Abstract The present study is part of the Flora of Espírito Santo project and aimed to survey and describe the morphological diversity of species of Bixaceae from Espírito Santo state, Brazil, as well as to provide data on geographical distribution, biology, and habitat of these species. To do so, fieldwork was carried out in several areas of Espírito Santo and the most important herbaria collections in the state were examined. Bixaceae in Espírito Santo is represented by the genus Bixa, with two species. Bixa atlantica, recently described and repeatedly misidentified as Bixa arborea, is a forest tree up to 20 m tall (rarely appearing as treelet or shrub in savannah-like vegetation), with spine fruits and lacking nectaries in the pedicel apex. Bixa orellana, on the other hand, is recognized as a shrub or treelet up to 5-6 m tall, with conspicuous nectaries in the pedicel apex. The species origin is uncertain, though it occurs sub-spontaneously in Espírito Santo state, where it is widely cultivated due to its value as a spice. In this paper we provide taxonomic descriptions, an identification key, geographic distribution maps, photographic plates and comments on the ecology, conservation, and recognition of both species.

Abstract In the present study, we present new geographic distribution records of Thismia hyalina and T. melanomitra for Pará State, increasing the number of species of Thismiaceae in this state to three, with the previous register of T. singeri. The three species can be separated by the thickness of the roots, the presence of tuberous stems, outer tepal shape and colour, inner tepal shape and colour, and mitre presence. The description, taxonomic, ecological and geographic distribution comments along with photo plates of the studied species are presented.

Abstract Myrtaceae is a diverse family in Brazil and the sixth most representative family in the Atlantic Forest. In Paraná, the Parque Nacional do Iguaçu (ParNa Iguaçu) is a large National Park and also one of the largest remnants of this phytogeographic domain. The objective of the present study was to carry out a floristic inventory of the Myrtaceae of the ParNa Iguaçu, presenting an identification key to the species, illustrations, conservation status evaluation, and comments on geographic distribution and phenology. The collections were carried out between May 2019 and March 2020 in two areas composed of Seasonal Semideciduous Forest and a transitional area to Mixed Ombrophilous Forest. In addition to the samples collected by us, material from other herbaria were also examined. Twenty-five native species and one exotic species of Myrtaceae were found, distributed in seven genera. Eugenia was the most representative genus with 11 species. Of the 26 species, seven are new occurrences for ParNa Iguaçu. From the samples collected in this research and other records in the northwest and west regions of the state of Paraná, the presence of Psidium striatulum in Seasonal Semideciduous Forest is confirmed. Eugenia myrciariifolia was the only species on Brazil’s endangered species list, the IUCN conservation status of which is Endangered (EN). The other species were considered as Least Concern (LC), but some of these species are restricted to certain areas or types of vegetation. Therefore, we conclude that ParNa Iguaçu contributes to the maintenance of these species in their natural environment.
桃金娘科是巴西的一个多样化科，是大西洋森林中第六大代表性科。Parque Nacional do iguau (ParNa iguau)是一个大型国家公园，也是该植物地理领域最大的遗迹之一。摘要本研究的目的是对帕纳伊瓜帕拉苏金桃科植物区系进行清查，提出物种鉴定要点、图例、保护现状评价，并对地理分布和物候进行评述。收集于2019年5月至2020年3月在两个由季节性半落叶林和混交林过渡区组成的地区进行。除了我们收集的样品外，还检查了其他植物标本室的材料。发现桃金娘科原生种25种，外来种1种，分属7属。最具代表性的属有11种。在26个物种中，有7个是ParNa iguaparu的新物种。根据本研究收集的样本和其他在帕拉南州西北部和西部地区的记录，证实了在季节性半落叶林中存在纹状斑胸草。巴西的濒危物种名单上，仅有一种是金桃红，其IUCN保护状态为濒危(EN)。其他物种被认为是最不受关注的(LC)，但其中一些物种仅限于某些地区或植被类型。因此，我们认为ParNa igua对这些物种在自然环境中的维持有贡献。

Abstract The flora of the Brazilian rupestrian grasslands represents a hotspot of species richness and endemisms. Stachytarpheta cassiae (Verbenaceae), is a micro endemic species, from which nothing is known. Here, we quantified the activity and intensity of vegetative and reproductive phenophases throughout 12 months and tested for their seasonality and their relationship with local climatic variables. Both vegetative and reproductive phenophases were continuous. No seasonality was observed in the vegetative phenophases and none of them was influenced by climatic variables. Only flower buds and mature fruits’ intensities showed seasonality in February (rainy season) and July (dry season), respectively. Accordingly, increased temperature and humidity combined explained increased production of flower buds whereas decreased rainfall explained increased mature fruits. Higher intensity in flower buds may respond to similar climatic conditions as other species in the community. However, S. cassiae is much different as it continues producing flowers continuously. Higher intensity of mature fruits in the dry season is expected as their seeds are abiotically dispersed. Due to constant flower and leaf production, S. cassia may be a key species for the conservation of many vertebrate and invertebrate species and for maintaining the biogeochemical functioning of the impoverished soils of the rupestrian grasslands.

Here, we quantified the activity and intensity of vegetative and reproductive phenophases throughout 12 months and tested for their seasonality and their relationship with local climatic variables. Both vegetative and reproductive phenophases were continuous. No seasonality was observed in the vegetative phenophases and none of them was influenced by climatic variables. Only flower buds and mature fruits’ intensities showed seasonality in February (rainy season) and July (dry season), respectively. Accordingly, increased temperature and humidity combined explained increased production of flower buds whereas decreased rainfall explained increased mature fruits. Higher intensity in flower buds may respond to similar climatic conditions as other species in the community. However, S. cassiae is much different as it continues producing flowers continuously. Higher intensity of mature fruits in the dry season is expected as their seeds are abiotically dispersed. Due to constant flower and leaf production, S. cassia may be a key species for the conservation of many vertebrate and invertebrate species and for maintaining the biogeochemical functioning of the impoverished soils of the rupestrian grasslands.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67284745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract A floristic inventory and a taxonomic treatment of Asteraceae from Serra da Confusão do Rio Preto in the state of Goiás are provided. Collections were carried out from July 2017 to December 2018 in a fragment of cerrado sensu stricto with transition to cerrado rupestre (rocky cerrado), for a total of 38 expeditions covering all seasons. Taxonomic treatment of the resulting specimens includes identification keys, diagnoses and descriptions, conservation status, endemism and examined material. A total of 59 species were found, belonging to 32 genera and 10 tribes. The predominant genera were Lessingianthus (8 spp.) and Chromolaena (5 spp.) while the predominant tribes were Vernonieae (19 spp.), Eupatorieae (13 spp.) and Heliantheae (7 spp.). The richness pattern for tribes was the same as recorded in other floristic inventories in the Cerrado domain, especially cerrado sensu stricto. Twenty-one of the species (35.6%) are restricted to Brazil while only Isostigma resupinatum is restricted to the state of Goiás. Conyza primulifolia, Lepidaploa cuiabensis and Lepidaploa sororia were new occurrences for the state.
摘要本文报道了Goiás州Serra da confus o do里约热内卢Preto的菊科植物区系清查和分类处理。从2017年7月到2018年12月，在塞拉多严格的塞拉多(cerrado sensu stricto)的一个片段中进行了收集，过渡到塞拉多鲁佩斯特(cerrado rupestre)，总共进行了38次探险，涵盖了所有季节。结果标本的分类处理包括鉴定键、诊断和描述、保存状况、地方性和检查材料。共发现59种，隶属于10个部落32属。优势属为小花属(8种)和花花属(5种)，优势属为Vernonieae(19种)、Eupatorieae(13种)和Heliantheae(7种)。部落的丰富度格局与塞拉多域其他植物区系调查结果一致，尤其是严格意义上的塞拉多。其中21种(35.6%)局限于巴西，只有异柱头属(iso柱头resupinatum)局限于Goiás州。报春花、贵州鳞翅目和云南鳞翅目是本州新出现的物种。
