Spintherobolus papilliferus in the rio Ribeira de Iguape basin: implications for the biogeography and conservation of an endangered species (Ostariophysi: Characiformes)

Spintherobolus papilliferus is an endangered characid endemic of the Atlantic Rainforest, known from sparse locations in the upper rio Tietê basin around the metropolitan area of São Paulo city, and from an affluent of rio Itapanhaú, a coastal stream in Bertioga, São Paulo State. In 2020, S. papilliferus was sampled from the rio Ribeira de Iguape basin in Juquitiba, São Paulo State, representing a new distributional record. We compared 17 morphometric and six meristic characters from all specimens with data from the rios Tietê and Itapanhaú. An overlap in the morphological data from the three populations was detected, except for five measure whose values are lower in rio Ribeira de Iguape. MANOVA and LDA revealed that this population differs significantly from the other two, showing shallower body and caudal peduncle, among other features. These morphological differences may be due to environmental selective pressures since rio Ribeira de Iguape drainage is marked by fast waters which can influence the shape of fish bodies over time. DNA-barcoding of all Spintherobolus species corroborate that the rio Ribeira de Iguape population belongs to S. papilliferus. We also present a hypothesis for the disjunct distribution of S. papilliferus involving headwater capture and discuss the implications for the conservation of this endangered species.

Spintherobolus papilliferus é um caracídeo endêmico da Mata Atlântica e ameaçado de extinção, conhecido de localidades esparsas na bacia do alto rio Tietê, região metropolitana da cidade de São Paulo, e de um afluente do rio Itapanhaú, um riacho costeiro em Bertioga, Estado de São Paulo. Em 2020, S. papilliferus foi amostrada na bacia do rio Ribeira de Iguape em Juquitiba, São Paulo, representando um novo registro de distribuição. Comparamos 17 caracteres morfométricos e seis merísticos dos exemplares com dados dos rios Tietê e Itapanhaú. Houve sobreposição nos valores dos dados exceto em cinco medidas cujos valores são menores no rio Ribeira de Iguape. MANOVA e LDA revelaram que esta população difere significativamente das demais populações, sendo estes exemplares caracterizados pelas menores alturas do corpo e pedúnculo caudal, dentre outras características. Estas diferenças morfológicas possivelmente decorrem de pressões ambientais, pois a drenagem do rio Ribeira de Iguape possui ambientes de corredeiras velozes que podem influenciar no formato do corpo dos peixes. DNA-barcoding de todas as espécies de Spintherobolus corroborou que a população do rio Ribeira de Iguape pertence à S. papilliferus. Apresentamos também uma hipótese para a distribuição disjunta de S. papilliferus envolvendo captura de cabeceiras e discutimos implicações para a conservação dessa espécie ameaçada.

First record of Mirinaba cadeadensis (Gastropoda: Strophocheilidae) in an anthropogenic shell mound from the Paraná coast, Southern Brazil

Mirinaba cadeadensis Lange de Morretes, 1952 is restricted to the Paraná state, and found at the municipalities of Morretes, São José dos Pinhais, Paranaguá, Matinhos, and Guaratuba, associated to the Serra do Mar mountains. In this paper, we report the first record of this species in an anthropogenic shell mound. Two shells of M. cadeadensis were located in the internal stratigraphic layers of the Boguaçu shell mound. This is also the first shell mound record for Mirinaba.

A three-year Herpetofauna survey from one of the largest remnants of the Atlantic Rainforest Biome (Reserva Natural Vale)

Here we present a three-year survey of amphibian and reptile species registered in the Vale Natural Reserve (VNR), located in the north of Espírito Santo, southeastern Brazil. The VNR, along with the Sooretama Biological Reserve (SBR) and other surrounding areas, form a forest block that constitutes one of the largest remnants of continuous forest in the Atlantic Forest biome. We systematically sampled the herpetofauna community from 2015 to 2018, using the method of active search method in 27 plots of RAPELD distributed in the different types of vegetation present in the area. We recorded 39 species of amphibians belonging to the order Anura, distributed in seven families and 40 species of reptiles belonging to 20 families distributed in three orders: Crocodylia, Testudines and Squamata. The supplementation the samplings with those records from occasional encounters was important for the survey of the region's herpetofauna, mainly for reptiles. We added four species (two lizards, one amphisbaenid and one snake) to the known list for the VNR-SBR forest block: Micrablepharus maximiliani, Strobilurus torquatus, Amphisbaena alba and Tantilla sp. We demonstrated that VNR contains a high species richness of amphibians and reptiles, with a high number of anurans being endemic to the Atlantic Forest biome. The present species inventory provided the most current approximation of known the richness and composition of species of the existing herpetofauna at Vale Natural Reserve, since the period of the gathering of records is quite recent (2015-2018). Also, it brings the knowledge of some community parameters as species richness and composition not only for the whole area of the Vale Natural Reserve, but also for its different vegetation types, with no inclusion of environments outside this reserve. Furthermore, the presence of threatened species, the addition of four species to the current list, and the potential for new species to occur, reinforce the role of VNR as an important area for the protection of amphibian and reptile biodiversity in the Atlantic Forest.(AU)

Fire effects on Atlantic Forest sites from a composition, structure and functional perspective / Efeitos do fogo na Mata Atlântica por meio de uma abordagem de composição, estrutura e funcional

Recently, some portions of the Atlantic Forest biome have been suffering an increase in forest fires, possibly changing its vegetation cover, composition, structure and functioning. Understanding these changes is critical to evaluate the present and future response of tropical forests to fire. Thus, the purpose of our study was to evaluate how diversity, structure and functioning of tree communities differed between burned and unburned sites. Two unburned and two burned forest patches were selected for floristic and phytosociological surveys. Then, we calculated species richness, Shannon diversity index, tree density and basal area, Importance Value Index for trees in each site and we assessed community weighted mean of six functional traits (maximum tree height, wood density, leaf length, leaf deciduousness, shade tolerance and dispersal mode). Diversity, species richness, tree density and basal area were similar between sites. We found changes in floristic composition, but did not verified variations in functional traits. Results indicate that recovery may be fast and that pioneer and early secondary species are occupying post burned sites (nine years old). One-time anthropogenic, superficial and low intensity fires might disrupt advanced stages of succession and start again the dynamics of species substitution.

Recentemente, algumas regiões do bioma Mata Atlântica têm sofrido com um aumento de incêndios, possivelmente modificando sua cobertura vegetal, composição, estrutura e funcionalidade. Compreender essas mudanças é imprescindível para avaliar as respostas, no presente e futuro, das florestas tropicais ao fogo. Assim, o objetivo do nosso estudo foi avaliar como a diversidade, estrutura e funcionamento das comunidades arbóreas diferem entre áreas queimadas e não queimadas. Dois fragmentos queimados e dois fragmentos não queimados foram selecionados para os levantamentos florísticos e fitossociológicos. Depois, foram calculadas a riqueza de espécies, o Índice de diversidade de Shannon, densidade da árvore e área basal, Índice de valor de importância para as espécies em cada uma das áreas e avaliamos a média de seis características funcionais (altura máxima da árvore, densidade da madeira, comprimento da folha, deciduidade foliar, tolerância a sombra e síndrome de dispersão). Diversidade, riqueza, densidade e área basal foram similares entre as áreas analisadas. Nós encontramos mudanças na composição florística, mas não foram verificadas variações nas características funcionais. Os resultados indicam que a recuperação pode ser rápida e que espécies pioneiras e secundárias iniciais estão ocupando as áreas queimadas cerca de nove anos depois. Um único incêndio antrópico, superficial e de baixa intensidade, pode interromper estágios avançados de sucessão e iniciar a nova dinâmica de substituição de espécies.

Small mammals from the lasting fragments of Araucaria Forest in southern Brazil: a study about richness and diversity

Rodents and marsupials together, form the most rich group of mammals in Brazil, they are distributed in all biomes, including Atlantic Forest, and can be used to analyze environmental quality. The Araucaria Forest is a threatened formation of the Atlantic forest with few areas remaining intact and a huge lack of knowledge about the potential of its secondary forest fragments to act as habitat refuges to native fauna. This study evaluated the species richness and diversity of non-volant small mammals among five vegetation types within a protected area in an Araucaria Forest area from southern Brazil. The sampling was made in six bimonthly campaigns during a year, by pitfall and live traps. This effort resulted in 875 captures of 625 individuals from 16 species. The most common species in Pine Plantation was Oligoryzomys nigripes, in Natural Regeneration forest was Thaptomys nigrita and Akodon montensis was most often captured in the other vegetation. Although differences in species composition were found among the different vegetation types, there was no significant difference in species richness. Nevertheless, true diversity values were significantly lower in the Pine Plantation. The results demonstrated that the substitution of native for exotic vegetation generated a negative impact on the group diversity. More studies, in other Araucaria Forest areas are necessary to allow better understanding of the processes driving this loss of diversity in this biome threatened by antropic action.(AU)

Vascular plants on inselberg landscapes in Espírito Santo state: bases for the creation of a protected area in southeastern Brazil

Inselbergs are granitic or gneissic rocky outcrops prevalent in the landscape of southeastern Brazil. These ecosystems represent islands of isolated habitats that harbor a peculiar flora with high richness and endemism. The present study lists the species of vascular plants occurring in the Pedra da Andorinha Complex, located in the municipality of Jerônimo Monteiro/Cachoeiro de Itapemirim, southern Espírito Santo state, aiming to generate subsidies for the creation of a protected area. The survey was performed between July 2017 and October 2018, resulting in a record of 121 species, 96 genera, and 40 families. Bromeliaceae (17), Orchidaceae (12) and Fabaceae (10) were the richest families. The phytophysiognomy of exposed rock vegetation comprises a greater number of species (79 species) compared to the woody rupicolous communities (42). Eighteen of the collected species are threatened by extinction; a new species was discovered; and five were described based on materials previously collected in the studied location — Alcantarea patriae, Anthurium martinellii, Coleocephalocereus uebelmanniorum, Stigmatodon attenuatoides and Pitcairnia azouryi, the first four being endemic to the region. We also found Tabebuia reticulata, a rare species among Brazilian flora. Our results highlight the biological importance of the Pedra das Andorinhas Complex and reinforce the need to create a protected area to preserve biodiversity and the regional natural heritage.

A checklist of aquatic macrophytes of the Guaraguaçu river basin reveals a target for conservation in the Atlantic rainforest

Describing and understanding distribution of species in natural ecosystems is the first step to establish conservation efforts. In aquatic habitats, macrophytes play a central role in promoting biodiversity and ecosystem functioning. This study aimed to create the first checklist of aquatic macrophyte species occurring in the Guaraguaçu river, the largest river in Paraná State coast, Brazil. Species herborized, identified and incorporated into the Herbarium collection of the Universidade Federal do Paraná. A total of 47 species were registered corresponding to 37 genera and 29 botanical families; Cyperaceae and Poaceae were the most representative families. In addition, the wide invasion of the non-native species Urochloa arrecta (Hack. ex T. Durand & Schinz) Morrone & Zuloaga was registered and the presence of the floating-leaved non-native species Nymphaea caerulea Savugny was recorded. Even so, the inventory shows a noteworthy richness of aquatic macrophytes species in the Guaraguaçu river, and it is clear macrophyte species reflect a gradient of anthropic impact and salinity in this tidal estuarine river. Our study contributes to the creation of public policies to aid in the protection of this river that represents a central site for biological conservation efforts, yet is constantly threatened by anthropic activities.

Reptile diversity in the Duas Bocas Biological Reserve, Espírito Santo, southeastern Brazil

Abstract The lack of information on the occurrence of species in a region limits the understanding of the composition and structure of the local community and, consequently, restricts the proposition of effective measures for species conservation. In this study, we researched the reptiles in the Duas Bocas Biological Reserve (DBBR), Espírito Santo, southeastern Brazil. We analyzed the parameters of the local community, such as richness, composition, and abundance of species. We conducted samplings from August 2017 to January 2019, through active search. We performed the samplings in nine standard plots of 250 meters in length. All individuals located in the plots or occasionally on the trails were registered. To evaluate sample effort to characterize the reptile community, we performed an accumulation curve of species, and to update the DBBR reptile list, we used as secondary data specimens deposited in collections and previously published studies. Considering primary and secondary data, we recorded 38 species, one chelonia, 13 lizards, and 24 snakes. Our study showed a richness of 15 additional species to the previous list of reptiles, increasing by about 40% the known richness to the area. We concluded that the DBBR holds a high richness of reptile species, representing 12% of the richness of reptiles of the Atlantic Forest and with a considerable number of endemic species in this biome. This suggests that the DBBR is an important forest fragment constituting a reservoir of the biodiversity of the reptiles of the Atlantic Forest.

Butterfly fauna (Lepidoptera, Papilionoidea) in a heterogeneous area between two biodiversity hotspots in Minas Gerais, Brazil

This paper investigates the butterfly fauna of the ‘Serra do Rola-Moça’ State Park, Minas Gerais, Brazil. We evaluate i) the seasonal variation of species richness and composition; and ii) the variation in composition of the local butterfly assemblage among three sampling sites and between the dry and rainy seasons. Sampling was carried out monthly between November 2012 and October 2013, using entomological nets. After a total sampling effort of 504 net hours, 311 species were recorded. One of them is endangered in Brazil, and eight are probable new species. Furthermore, two species were new records for the region and eight considered endemic of the Cerrado domain. There was no significant difference in species richness between the dry and the rainy seasons, however the species composition varies significantly among sampling sites. Due to its special, heterogeneous environment, which is home to a rich butterfly fauna, its preservation is important for the conservation of the regional butterfly fauna.

Use of microhabitats affects butterfly assemblages in a rural landscape

Landscapes composed of small rural properties may support highly heterogeneous habitat, because they often cover distinct types of land uses adjacent to surrounding forest fragments. Many butterfly species may benefit from this kind of landscape, as very distinct microhabitats can be found in a very restricted spatial scale. To better understand how different microhabitats are related to fragmentation in rural landscapes the present study collected the butterfly fauna in 18 sampling point sites, representing distinct types of forest edges and forest interiors. Although closely located, these sites showed no spatial autocorrelation. Instead, a major distinction in species richness and composition was found among forest interior and edge habitats while no significant difference was found in species composition among distinct edge types. Therefore, the high segregation of butterfly assemblages found in a very restricted geographic scale suggests the presence of two different groups of butterflies that respond independently to forest fragmentation, the forest interior assemblages and forest edge assemblages. This distinction of butterfly assemblages related to forest interior and forest edges were already reported, but our results highlights that these differences are found mostly due to species turnover between those habitats. In other words, both microhabitat types present a high number of specialized species compared to a smaller fraction of generalist species that may occurs in both microhabitats. In the case of Atlantic Forest, the species of special conservation concern are those true specialized in forest interior habitats and not those specialized in forest edges, thus the present study corroborates the importance of sampling different microhabitats when studying fragmentation processes, both inside and outside of fragments...

Fragmentos urbanos têm se tornado verdadeiros refúgios para animais e plantas que buscam nessas áreas com recursos para a sua sobrevivência apresentando, sobretudo, uma grande importância para a conservação de aves que necessitam de um espaço mínimo para encontrar abrigo, alimento, locais propícios para nidificar e outros indivíduos da mesma espécie para reproduzir. Nesse sentido, o estudo teve como objetivo elaborar uma lista das espécies de aves registradas em um fragmento urbano da Zona da Mata Mineira, assim como avaliar a flutuação de aves aquáticas durante um período de obras no local. Em seis anos de coleta, que foram divididos entre antes, durante e após a obra, foram registradas 160 espécies de aves, com seis espécies novas para a região. Houve variação na riqueza de espécies de aves associadas a ambientes aquáticos durante o estudo e o desaparecimento de Coraciiformes. Os resultados confirmaram o potencial de fragmentos urbanos em abrigar espécies de aves ameaçadas e que vêm enfrentando dificuldades em manter suas populações.

Birds of the Botanical Garden of the Federal University of Juiz de Fora, Minas Gerais, Brazil. Urban fragments have become true refuges for animals and plants that seek resource areas for their survival and, above all, are of great importance for conservation of birds that have minimal space to find shelter, food, breeding sites and others. In this sense, the present study aimed to draw up a list of bird species recorded in an urban fragment of Zona da Mata Mineira, as well as to evaluate the fluctuation of waterfowls during a period of construction on site. In six years of collection, which were divided between before, during and after the building, 160 species were recorded with six new species to the region. There was variation in bird species associated with aquatic environments during the study and in the disappearance of Coraciiformes. The results confirmed the potential of urban fragments to house endangered bird species that are facing difficulties in maintaining their populations.

Mamíferos de médio e grande porte do Parque Ecológico Rancho dos Bugres, sul do Brasil / Medium-to large-bodied mammalian fauna of Parque Ecológico Rancho dos Bugres, Southern Brazil

A fauna de mamíferos está sob ameaça, principalmente na Floresta Atlântica da América do Sul. Essa é uma ecorregião fortemente ameaçada pela perda e fragmentação do hábitat, processos que influenciam diretamente o funcionamento dos ecossistemas. Desenvolvemos um inventário de mamíferos em um remanescente florestal no sul de Santa Catarina, Brasil, objetivando conhecer a composição e a diversidade de mamíferos de médio e grande porte. O estudo foi realizado em três transectos no Parque Ecológico Rancho dos Bugres (PERB, 28º29'S e 49º15'W) através de armadilhas fotográficas, resultando em um esforço total de 630 armadilhas/dia. Obtivemos 106 registros independentes de nove espécies de mamíferos, das ordens Carnivora, Cingulata e Rodentia. Os resultados do nosso estudo aumentam o conhecimento sobre a diversidade e distribuição de mamíferos na Mata Atlântica subtropical. Além disso, podem ser utilizados para gerar subsídios para a implementação de estratégias de conservação na fauna de mamíferos, contribuindo para preencher parte da lacuna no conhecimento da distribuição de mamíferos de médio e grande porte em uma região pouco estudada.

Mammalian fauna is under several threat, mainly in Atlantic Forest of South America. Atlantic Forest is an ecorregion strongly endangered by habitat loss and fragmentation, processes that influencing directly the ecosystems functioning. We developed a mammalian inventory in a forest remnant in southern of Santa Catarina, Brazil, aiming to know the medium- to large-bodied mammalian composition and diversity. The study was carried in three transects within Parque Ecológico Rancho dos Bugres (PERB; 28º29’S and 49º15’W) through camera-traps, resulting in a total effort of 630 traps/day. We obtained 106 independent records of nine mammalian species, within the orders Carnivora, Cingulata and Rodentia. The results of our study can increase the knowledge about the mammalian diversity and distribution in the subtropical Atlantic Forest. Moreover, can be generated subsidies for the implementation of conservation strategies on mammalian fauna and contributing to filling part of the gap in the knowledge of distribution of medium- to large-bodied mammals in a region poorly studied.
