Análise da Condutividade Hidráulica Saturada em uma Floresta de Cedro, Madrid, Espanha

A condutividade hidráulica saturada do solo (K0) é de grande importância para a hidrologia, especialmente no contexto da infiltração, onde apresenta grande influência nas condições de geração de escoamento superficial direto, tendo como consequências a formação de inundações, erosão do solo e transporte de sedimentos. Além disso, tem papel fundamental na agricultura, por contribuir na infiltração e disponibilização de água para as plantas, e também na conservação do solo e do meio ambiente. Diante do exposto, o objetivo deste trabalho foi estimar e analisar o comportamento da condutividade hidráulica saturada do solo associada aos seus atributos físicos e declividade e avaliar o escoamento superficial direto, em uma área de floresta de Cedrus deodara, em Madrid, na Espanha. Para tanto, foram realizados testes de infiltração com o método dos anéis concêntricos em três pontos na área de estudo, a fim de obter dados que foram ajustados pelo modelo de Horton para estimar a condutividade hidráulica saturada do solo, e também foram realizados testes com um simulador de chuvas a fim de determinar o coeficiente de escoamento superficial. Foram retiradas amostras deformadas do solo para determinação de seus atributos físicos. Os resultados mostraram que o modelo de Horton foi adequado para estimar a condutividade hidráulica saturada do solo. Os valores dos atributos físicos do solo e a declividade influenciaram a condutividade hidráulica saturada do solo. A matéria orgânica associada à declividade do solo proporcionaram os maiores valores de K0. O escoamento superficial direto apresentou relação inversa à condutividade hidráulica saturada do solo

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Stream flow regime of springs in the Mantiqueira Mountain Range region, Minas Gerais State

The stream flow regime of four springs located in the Mantiqueira Mountain Range region (MG) was evaluated and correlated to the respective recharge area, relief characteristics, land cover and physical and hydrologic soil characteristics. The streamflow regime was characterized by monitoring of discharges, calculating the surface runoff and specific discharge and by modeling the discharge over the recession period using the Maillet method. As all recharge areas have similar relief the effect of it on the streamflow was not possible to identify. Analysis included determining the effect of drainage area size, soil characteristics and land cover on the indicators of the streamflow regime. Size of the recharge area had a positive influence on the indicators mean discharge and surface runoff volume and on the regulation of the streamflow regime (springs L4 and L1). The spring under the smallest area of influence provided the worst results for the above mentioned indicators (spring L3). The effect of forest cover (natural and planted), associated with soil characteristics, was evidenced by the indicators surface runoff (in depth) and specific yield, both independent of the recharge area size (springs L4 and L2). The interaction of area size, soil characteristics and forest cover (natural and planted) provided the best results for all indicators of streamflow regime in the springs studied in the Mantiqueira Mountain Range (spring L4)

Osteohistology and growth dynamics of the Brazilian noasaurid Vespersaurus paranaensis Langer et al., 2019 (Theropoda: Abelisauroidea)

Although the knowledge of bone histology of non-avian theropods has advanced considerably in recent decades, data about the bone tissue patterns, growth dynamics and ontogeny of some taxa such as abelisauroids are still limited. Here we describe the bone microstructure and growth dynamics of the Brazilian noasaurine Vespersaurus paranaensis using five femora and six tibiae and quantify the annual growth marks through retrocalculation of missing ones to estimate ontogenetic ages. The femoral series comprises four femoral histological classes (FHC I-IV), varying from two annuli or LAGs to seven LAGs. Femora show that sexual maturity was achieved around the seventh to tenth year of life, whereas the tibiae suggest it was earlier (around three to five years old). Tibiae represent three histological classes (THC I-III) displaying from three to nine LAGs. Two tibiae (THC III) exhibit an external fundamental system indicating that these specimens reached full skeletal size. The heterogeneous maturity observed in Vespersaurus hind limb bones could result from differential allometry scaling between femora and tibiae length with the body length. The predominant parallel-fibered bone matrix suggests that Vespersaurus grew more slowly than most theropods, including other abelisauroids, in a pattern shared with the noasaurines Masiakasaurus knopfleri from Madagascar and CPPLIP 1490 from Brazil. This deviation from the typical theropod growth pattern may be mainly correlated with small body size, but also may related to resource limitation imposed by the arid climate prevailing in southwestern Gondwana during Cretaceous. Moreover, given the ecological and phylogenetic similarities among these taxa, such features would probably be apomorphic within Noasauridae

Cyperus prophyllatus: An endangered aquatic new species of Cyperus L. (Cyperaceae) with a exceptional spikelet disarticulation pattern among about 950 species, including molecular phylogenetic, anatomical and (micro)morphological data.

Cyperus prophyllatus, an endangered new species of Cyperus (Cyperaceae) from an aquatic ecosystem of the Atlantic Forest, Espírito Santo State, southeastern Brazil, is described and illustrated. The spikelet morphology of Cyperus prophyllatus is unique among the c. 950 species of Cyperus in having both a conspicuous spikelet prophyll and a corky rachilla articulation, which remain persistent at the base of the spikelet after disarticulation. Our molecular phylogenetic data support the placement of C. prophyllatus in the C3 Cyperus Grade and more precisely in the clade representing Cyperus sect. Oxycaryum, which also includes C. blepharoleptos and C. gardneri. Anatomical and (micro)morphological analyses corroborate the phylogenetic results, provide a better understanding of ecology and taxonomy, as well as reveal compatibility of structures with survival and dispersion in aquatic environments. A distribution map, table with distinctive characters of allied species, and conservation status are made available

Impacts of Selenium Foliar Biofortification on the Biochemical Composition and Grain Yield of Rice Cultivars

Selenium Se is an essential micronutrient for humans and animals linked to important biological functions in the body, where its deficiency has been associated with serious diseases. Rice is essential in feeding more than half of the world's population. Some studies show beneficial effects of Se in higher plants. Thus, the objective of this work was to determine the effect of leaf Se doses on biofortification, agronomic characteristics and biochemical characteristics of the grains of two irrigated rice cultivars. The factors under study were five doses of Se (0, 30, 60, 90 and 120 g ha-1) using as sodium selenate source (Na2SeO4), and two rice cultivars (IRGA-424 and IRGA-426). The leaf application of Na2SeO4 allowed the biofortification of rice grains with Se, however, it affected its yield and some biochemical components. The cultivar IRGA-426 Se shows superior because it allows a higher concentration of Se in the grains, presents higher yield and better nutritional content. The cultivar IRGA-426 with the dose 60 g ha-1 Se was the viable combination to increase the content of Se in the grains, which may result in benefits for the health and food safety of the population
