“…Lagoas e lagos foram os ambientes mais pesquisados no Estado do Espírito Santo em relação às comunidades fitoplanctônicas e perifíticas (Figura 2), com doze e cinco trabalhos Minas Gerais e onde se localiza o Pico da Bandeira, o ponto mais alto da região Sudeste brasileira (Cardoso et al 2019); poucas amostragens foram realizadas nos municípios da região centroserrana e nenhuma nos municípios do extremo sul do estado (Figura 3).…”

O estado do Espírito Santo (Brasil) tem sido pouco explorado em termos de microalgas e cianobactérias de ambientes aquáticos continentais, apesar de possuir doze bacias hidrográficas, tendo a maior contribuição, em termos de volume de água da bacia do rio Doce. Este fato é resultado do baixo número de pesquisadores e instituições com pesquisas ecológicas e taxômicas. As primeiras investigações limnológicas com microalgas e cianobactérias ocorreram na década de 90, tendo avanço considerável em lagoas costeiras, lagos, rios e represas a partir da década de 2000, tanto com fitoplanctôn quanto com o perifíton, devido ao incremento de pesquisadores e editais de pesquisa. Este estudo cienciométrico visou identificar tendências das pesquisas já realizadas, apontando os ecossistemas aquáticos mais estudados e os autores dos artigos. Os resultados evidenciaram que a maioria dos estudos se concentrou na ecologia das comunidades, com listas de táxons; raros foram os estudos taxonômicos; poucos foram os trabalhos experimentais para compreensão de fatores reguladores das comunidades. Inúmeras lacunas precisam ser preenchidas, especialmente no que tange ao: levantamento da biodiversidade nas diferentes regiões do estado, com ênfase em taxonomia; desenvolvimento de pesquisas experimentais para compreensão de fatores reguladores das comunidades; estudos preditivos frente a impactos ambientais; uso destas comunidades como bioindicadores de impactos ambientais; estudos biotecnológicos com microalgas; pesquisas que abordem impactos na saúde pública relacionados, principalmente, com as florações de cianobactérias potencialmente tóxicas; realização de testes de hipóteses ecológicas. Há também a necessidade e relevância de publicações em revistas internacionais de maior impacto e com colaboradores nacionais e internacionais e o estabelecimento de parcerias com instituições externas ao Espírito Santo e ao Brasil. Os novos direcionamentos favorecerão o incremento do conhecimento das comunidades fitoplanctônica e perifítica nos ecossistemas aquáticos continentais do Espírito Santo e fornecerão subsídios para a tomada de medidas de recuperação e/ou preservação. CONTINENTAL MICROALGAE AND CYANOBACTERIA IN ESPÍRITO SANTO STATE: PAST, PRESENT AND FUTURE: The Espírito Santo State (Brazil) has been little explored in terms of microalgae and cyanobacteria from inland waters, despite its twelve hydrographic basins and being the greatest contribution in water volume of the Doce river basin. This fact is the result of the low number of researchers and institutions with research lines about freshwater ecology and microalgae taxonomy. Literature records indicate that the early limnological researches that studied microalgae were published in the 1990s, with a considerable increase in studies in coastal lagoons, lakes, rivers, and dams from the 2000s onwards, about phytoplankton and periphyton, due to the increase in the number of researchers and more research notices. The present scientometric work aimed to identify trends in the past studies, showing the aquatic ecosystems with the greatest number of studies and the authors of the articles. Our results showed that most studies focused on aquatic ecology and the community with lists of taxa; taxonomic studies were rares; there is little experimental work to understand community regulatory factors. Numerous gaps need to be filled, especially regarding to biodiversity in different regions of the state, with accurate taxonomy studies; more experimental research to understand regulatory factors in communities and predictive studies on environmental impacts; biotechnological studies; research related to public wealth and cyanobacteria blooms; and studies testing ecological hypotheses. It is also necessary to consider the needs and relevance of publications in international journals with greater impact and with national and international collaborators, establishing partnerships with institutions outside Espírito Santo and Brazil. The new directions will favor the increase of knowledge of the phytoplankton and periphytic communities in the continental aquatic ecosystems of Espírito Santo and will provide subsidies for taking measures for their recovery and/or preservation.

Verbenaceae in Itacolomi State Park, Minas Gerais, Brazil: richness, geographical distribution, and a new synonym for Stachytarpheta commutata

2023

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.

Cunoniaceae from Caparaó National Park, Mantiqueira Mountain Range, Brazil

A floristic treatment is presented for Cunoniaceae in the Caparaó National Park (PNC), located in the Mantiqueira Mountain Range, on the border of the Minas Gerais and Espírito Santo states. This conservation unit comprises the highest mountain peak in southeastern Brazil, Bandeira Peak, at 2,890 m of elevation. Its vegetation encompasses different phytophysiognomies, including Dense Ombrophilous Forests, Montane Semi-deciduous Seasonal Forests, and High-Altitude Grasslands. Cunoniaceae was represented in the PNC by four species: Lamanonia ternata, L. ulei, Weinmannia humilis, and W. paulliniifolia. To contribute to further taxonomic studies and species conservation in the Mantiqueira Mountain Range, morphological descriptions, identification keys, photographs in vivo, and comments on the taxonomy, geographic distribution of the recorded species are provided.
