1. Brazilian herbaria: an overview
ABSTRACT Herbaria represent irreplaceable repositories of biodiversity and are used to answer questions about conservation, ecology, systematics, and other sciences. In this sense, we characterize the infrastructure, human resources, and idiosyncrasies of Brazilian herbaria. To achieve this goal, curators were sent a structured and standardized questionnaire

2. Taxonomic relevance of leaf anatomy in Banisteriopsis C.B. Rob. (Malpighiaceae)
ABSTRACT We describe the leaf anatomy of 42 of the 60 species of the genus Banisteriopsis, one of the largest and most diverse genera of Malpighiaceae in the Cerrado domain. Our aim was to identify anatomical leaf characters useful for the taxonomy and systematics of this morphological diverse genus. Expanded leaves from herbarium specimens were rehydrated a

3. Ensino de Ecoico em Pessoas com Transtorno do Espectro Autista: Revisão Sistemática de Literatura
RESUMO: A literatura tem demonstrado uma grande lacuna em estudos com o objetivo de estabelecer ecoico em pessoas com Transtorno do Espectro Autista (TEA). Assim sendo, este trabalho teve por objetivo identificar o acervo de pesquisas direcionadas para o ensino de ecoico em indivíduos com TEA. A revisão foi pautada no modelo Preferred Reporting Items for S

4. Morphological diversity of foliar trichomes in Asteraceae from Sand-fields of the Pampa biome, Rio Grande do Sul State, Brazil
RESUMO Asteraceae é a maior família das angiospermas e ocorre predominante em áreas campestres. Este estudo buscou identificar e caracterizar os tricomas foliares de 34 espécies de Asteraceae dos Campos de Areais do bioma Pampa por meio de análises da epiderme (vista frontal e transversal) em microscopia de luz e eletrônica de varredura.

5. Geochronological systematics of the Huayna Potosí, Zongo and Taquesi plutons, Cordillera Real of Bolivia, by the K/Ar, Rb/Sr and U/Pb methods
Abstract The Huayna Potosi, Zongo and Taquesi are Triassic plutons located at the core of the Real Cordillera of Bolivia. In this paper, several Rb-Sr and K-Ar ages obtained in the past at the São Paulo Geochronology Laboratory, yet unpublished, will be presented, along with newer U-Pb Sensitive High-Resolution Ion Microprobe (SHRIMP) determinations made in

6. Systematics of the Neotropical genus Loxozus (Diptera: Neriidae), with notes on distribution and sexual dimorphism
ABSTRACT The monotypic genus Loxozus Enderlein, 1922 is redescribed. After examining the holotypes of Tetanocera cornuta Walker, 1853 and Loxozus clavicornis Enderlein, 1922, we confirm that these species are synonyms and reiterate that the correct name of the nominal species is Loxozus cornutus (Walker, 1853). The male of L. cornutus is described for the fi

7. A phylogenetic investigation of the Neotropical genus Alphamenes van der Vecht, 1977 (Hymenoptera, Vespidae, Eumeninae)
ABSTRACT Advances in potter wasp systematics have been achieved recently, with classificatory changes resulting from analyses based upon large scale molecular datasets. For the Neotropics, recent hypotheses point to the occurrence of an exclusive clade recognized within the tribe Eumenini. In this group, several contributions regarding taxonomy and systemati

9. Reproductive morphology and phenological aspects of one morphological variant of Hypnea pseudomusciformis (Gigartinales, Rhodophyta)
ABSTRACT Hypnea pseudomusciformis was recently described from South America, and has three morphological variants: “musciformis”, “nigrescens”, and “valentiae”. Information on the biology of these variants may help to explain this species’ wide morphological variation despite the absence of genetic divergence among variants. More morphological

10. New initiatives for Brazilian aquatic plant data management
ABSTRACT Initiatives directed at managing information on aquatic plants can support different areas of scientific research, educational practices and political decisions for sustainable management and protection of wetlands and natural resources, as well as reveal knowledge gaps regarding aquatic plants and wetlands. Furthermore, such initiatives can contrib

11. Review of the family Rivulidae (Cyprinodontiformes, Aplocheiloidei) and a molecular and morphological phylogeny of the annual fish genus Austrolebias Costa 1998
ABSTRACT The family Rivulidae is the fourth most diverse clade of Neotropical fishes. Together with some genera of the related African family Nothobranchiidae, many rivulids exhibit a characteristic annual life cycle, with diapausing eggs and delayed embryonic development, which allows them to survive in the challenging seasonal ponds that they inhabit. Rivu

12. Systematics of Clupeiformes and testing for ecological limits on species richness in a trans-marine/freshwater clade
RESUMO Clupeiformes (apapás, sardinhas e manjubas) são um clado globalmente distribuído com quase 400 espécies marinhas, de água doce e diádromas. Embora mais conhecida pela presença de peixes filtradores formadores de cardumes, este grupo apresenta uma diversidade de guilda e habitats tróficos. A teoria sugere que a riqueza de espécies em clados é
