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.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285101","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}

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.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285007","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}

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.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285416","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}

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.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285365","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}

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.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285304","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}

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.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285429","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}

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.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":null,"pages":null},"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}
