1. Morphology and biometry of the reproductive organs of adult males of Trachemys scripta elegans reared in São Paulo state, Brazil
RESUMO: Trachemys scripta elegans é um quelônio subaquático americano ilegalmente comercializado em pet shops brasileiros. Ao ser abandonado na natureza, compromete as espécies nativas, ameaçando à biodiversidade local. No entanto, pouco se conhece sobre o desenvolvimento corporal e a estrutura do seu aparelho reprodutor. O objetivo do presente trabalh

2. Licófitas e samambaias do Parque Estadual Monte Alegre (PEMA), Pará, Brasil
RESUMO O Cerrado é um importante domínio fitogeográfico brasileiro, uma vez que abrange porcentagem considerável do território nacional. Nesse domínio há estimativas de 241 a 284 espécies de samambaias e licófitas, apesar disso, há poucos trabalhos ressaltando-as nesse ambiente, assim o objetivo desse estudo foi realizar um levantamento das plantas

4. Redescription of Ventania avellanedae (Stylommatophora: Odontostomidae), a land snail endemic to the Ventania Mountain System, Argentina
ABSTRACT Although the presence of apertural folds and lamellae is the most recognizable character of the Odontostomidae, some species lack them, mostly in Anctus Martens, 1860, Bahiensis Jousseaume, 1877 and Moricandia Pilsbry & Vanatta, 1898. Eudioptus avellanedae Doering, 1881 - a slender odontostomid species that lacks even the slightest trace of folds or

5. Fruit of Lepidaploa (Cass.) Cass. (Vernonieae, Asteraceae): anatomy and taxonomic implications
ABSTRACT Lepidaploa is a taxonomically complex genus of Vernonieae, which is difficult to delimit morphologically due to vegetative and reproductive characters that overlap with Chrysolaena and Lessingianthus. Anatomical studies of cypselae are taxonomically useful for delimiting subtribes, genera and species of Asteraceae, and especially within Astereae and

6. Variation in male reproductive system characters in Corydoradinae (Loricarioidei: Callichthyidae) reflects the occurrence of different lineages in this subfamily
RESUMO A família Callichthyidae compreende um grupo monofilético bem corroborado, dividida em duas subfamílias: Corydoradinae e Callichthyinae. Uma proposta recente, baseada em dados moleculares, sugeriu que a subfamília Corydoradinae é composta por nove linhagens, possivelmente gêneros. As espécies pertencentes a cada uma destas linhagens possuem ext

7. REDESCRIPCIÓN DE POTAMOLITHUS SUPERSULCATUS PILSBRY, 1896 (GASTROPODA, TATEIDAE) DEL SUR DE LA CUENCA DEL PLATA
ABSTRACT The genus Potamolithus Pilsbry, 1896 (Gastropoda; Tateidae), has 31 species, 22 of which are distributed in Argentina in Del Plata basin, defining the Uruguay River and the Río de la Plata as a “hotspot” of diversity in freshwater gastropods. However, most of its species has been described only by conchology characters and a few has anatomical

8. Cladistic analysis of the Argentinian species of the genus Bostryx (Gastropoda, Stylommatophora) based on morphological evidence
ABSTRACT The genus Bostryx Troschel, 1847 is found exclusively in South America, from Ecuador to Chile and mainly in the Andes mountain range. The phylogeny of Argentinian species of Bostryx was based on morphological characters of 19 species from Argentina, 5 from Peru and 7 from Bostryx-related genera, belonging to Bulimulidae and Odontostomidae. A matrix

9. Characterization and selection of interspecific hybrids of Brachiaria decumbens for seed production in Campo Grande - MS
Abstract The breeding program Brachiaria developed by Embrapa Beef Cattle provides studies to obtain forage with agronomic characters desired by farmers. In this regard, in 2013 and 2014, a study was carried out in order to select the best Brachiaria decumbens intraspecific hybrids, which are superior in relation to production, forage nutritional value, and

10. Phenodynamics of five orchids species growing on rock outcrops in the Chapada Diamantina Mountains in northeastern Brazil
ABSTRACT We evaluated the vegetative and reproductive phenological patterns of the orchids Cattleya elongata, Cyrtopodium aliciae, Epidendrum orchidiflorum, Epistephium lucidum, and Sobralia liliastrum (Orchidaceae) growing on sandstone outcrops in the Chapada Diamantina Mountains in northeastern Brazil. Phenological events were associated with abiotic facto

11. A Synopsis of Sloanea (Elaeocarpaceae) in the Neotropical extra-Amazonian Region
ABSTRACT The genus Sloanea is comprised of 150 species, of which about 50 occur in Brazil among several vegetation types but mainly the Amazon and Atlantic forests. The present work provides a synopsis of the Neotropical species of Sloanea in the extra-Amazonian region based on a recent revision of the genus. In general, morphologically Sloanea comprises lar

12. Polyphysaceae (Dasycladales, Chlorophyta) in Todos os Santos Bay, Bahia, Brazil
In this paper, we summarize the diversity of Polyphysaceae species in Todos os Santos Bay, in the state of Bahia, Brazil. On the basis of ten years of collections and the analysis of herbarium material, six species have been recorded for the area: Acetabularia caliculus J.V.Lamour. in Quoy & Gaimard; A. crenulata J.V.Lamour.; A. schenckii Möbius; Parvocauli
