An Analysis of the Opinions of Alabama Board of Nursing-Approved Continuing Education Providers on Regulatory Issues Impacting Their Services
Authors: Terry Allison J.
Published: December 2018

Few research studies have focused on the opinions of providers of continuing education in nursing about regulatory issues affecting their practice or services. A study was performed at the Alabama Center for Nursing to assess providers' willingness to use a new, mandated electronic system to transmit continuing education data to the Alabama Board of Nursing and the effectiveness of implementing the system. An analysis of data submitted via an online survey of continuing education providers revealed that, overall, providers were receptive to using the new technology and that neither the providers nor the nurses they served experienced excessive difficulty with the electronic transfer process. Although there was evidence of some resistance to the new technology, the data indicated a stronger acceptance and willingness of providers and licensees to use the technology as a positive tool in data management.

Hodge–Dirac, Hodge-Laplacian and Hodge–Stokes operators in $L^p$ spaces on Lipschitz domains
Authors: McIntosh Alan G.R. , Monniaux Sylvie
Published: December 2018

This paper concerns Hodge–Dirac operators

D_{{}^\Vert}=d+\underline{\delta}

acting in

L^p(\Omega, \Lambda)

where

\Omega

is a bounded open subset of

{\mathbb{R}}^n

satisfying some kind of Lipschitz condition,

\Lambda

is the exterior algebra of

{\mathbb{R}}^n

,

d

is the exterior derivative acting on the de Rham complex of differential forms on

\Omega

, and

\underline{\delta}

is the interior derivative with tangential boundary conditions. In

L^2(\Omega,\Lambda)

,

\underline{\delta} = {d}^*

and

D_{{}^\Vert}

is self-adjoint, thus having bounded resolvents

\{({\rm I}+itD_{{}^\Vert})^{-1}\}_{t\in{\mathbb{R}}}

as well as a bounded functional calculus in

L^2(\Omega,\Lambda)

. We investigate the range of values

p_H < p < p^H

about

p=2

for which

D_{{}^\Vert}

has bounded resolvents and a bounded holomorphic functional calculus in

L^p(\Omega,\Lambda)

. On domains which we call very weakly Lipschitz, we show that this is the same range of values as for which

L^p(\Omega,\Lambda)

has a Hodge (or Helmholz) decomposition, being an open interval that includes 2. The Hodge-Laplacian

\Delta_{{{}^\Vert}}

is the square of the Hodge–Dirac operator, i.e.,

-\Delta_{{}^\Vert}={D_{{}^\Vert}}^2

, so it also has a bounded functional calculus in

L^p(\Omega,\Lambda)

when

p_H < p < p^H

. But the Stokes operator with Hodge boundary conditions, which is the restriction of

-\Delta_{{}^\Vert}

to the subspace of divergence free vector fields in

L^p(\Omega,\Lambda^1)

with tangential boundary conditions, has a bounded holomorphic functional calculus for further values of

p

, namely for max

\{1,{p_H}_S\} < p < p^H

where

{p_H}_S

is the Sobolev exponent below

p_H

, given by

1/{{p_H}_S} =1/{p_H}+1/n

, so that

{{p_H}_S} < 2n/(n+2)

. In 3 dimensions,

{p_H}_S < 6/5

.

We show also that for bounded strongly Lipschitz domains

\Omega

,

p_H < 2n/(n+1) < 2n/(n-1) < p^H

, in agreement with the known results that

p_H < 4/3 < 4 < p^H

in dimension 2, and

p_H < 3/2 < 3 < p^H

in dimension 3. In both dimensions 2 and 3,

{p_H}_S<1

, implying that the Stokes operator has a bounded functional calculus in

L^p(\Omega,\Lambda^1)

when

\Omega

is strongly Lipschitz and

1 < p < p^H

Assessing the Effects of the Smartphone as a Learning Tool on the Academic Achievement of School-Based Agricultural Education Students in Louisiana
Authors: Smith H. Eric , Blackburn J. Joey , Stair Kristin S. , Burnett Michael F.
Published: December 2018

The purpose of this preexperimental study was to determine the effects of a blended learning environment on school-based agricultural education students’ ability to identify 30 species of trees by leaves. Louisiana agriculture teachers were recruited based on district policy regarding whether students could use smartphones for learning in the classroom. The treatment group utilized smartphone technology to aid in the identification of tree species, while the comparison group utilized traditional, printed materials. All students were taught via guided inquiry and engaged in multiple formative assessments during the course of the research study. No statistically significant differences were found between the groups on the posttest tree leaf identification. It is recommended that future research be conducted over a longer duration of time to better measure long-term performance and learning gains. Further, more research should be conducted to determine if motivational differences exist based on utilizing smartphones for learning. Teachers who desire to incorporate the smartphone into blended learning environments can do so without diminishing student achievement.

Published: December 2018

Introduction

Smoking during pregnancy is a risk factor for adverse pregnancy outcomes. Data on the correlation between passive maternal smoking and pregnancy outcomes remain limited. We investigated the effect of active smoking and environmental tobacco smoke (ETS) during pregnancy on neonatal birthweight, including the risk for low birthweight (LBW).

Material and methods

The study was conducted between 2010 and 2012. A group of 8625 women were surveyed during postpartum hospitalization. Outcome measures included mean birthweight of newborns. Additionally, odds ratios with confidence intervals were calculated to investigate the risk for LBW in active and passive smoking groups of mothers.

Results

Lower birthweight (46 g – 307 g; p < 0.05) and a higher risk for LBW (OR = 1.35, 95% CI: 1.05–1.75; p < 0.05) were observed in all infants born to smoking mothers. A negative effect of ETS in pregnancy on the reduction of mean birthweight was also found. Additionally, we analyzed the cumulative effect of active and passive smoking on neonatal birthweight. A statistically significant reduction in neonatal weight at birth was found in a group of women who smoked actively and passively during pregnancy (130 g; p < 0.05).

Conclusions

Smoking is associated with decreased birthweight and in a group of active smoking mothers increased risk for LBW. This effect is dose-dependent and is also present in a group of women who smoked before pregnancy. There is also a cumulative effect of active smoking and ETS causing decreased neonatal birthweight and increased risk for low birthweight.
High time-resolved measurement of stable carbon isotope composition in water-soluble organic aerosols: method optimization and a case study during winter haze in East China

Published: December 2018

Abstract. Water soluble organic carbon (WSOC) is a significant fraction of organic carbon (OC) in atmospheric aerosols. WSOC is of great interest due to its significant effects on atmospheric chemistry, the Earth’s climate and human health. Stable carbon isotope (δ13C) can be used to track the potential sources and investigate atmospheric processes of organic aerosols. In this study, a method of simultaneously measuring the mass concentration and δ13C values of WSOC from aerosol samples is established by coupling the Gas Bench II preparation device with isotopic ratio mass spectrometry. The precision and accuracy of isotope determination is better than 0.17 ‰ and 0.5 ‰, respectively, for samples containing carbon larger than 5 μg. This method is then applied for the high time-resolution aerosol samples during a severe wintertime haze period in Nanjing, East China. WSOC varies between 3–32 μg m−3, whereas δ13C-WSOC ranges from −26.24 ‰ to −23.35 ‰. Three different episodes (e.g., namely the Episode 1, the Episode 2, the Episode 3) are identified in the sampling period, showing a different tendency of δ13C-WSOC with the accumulation process of WSOC aerosols. The increases in both the WSOC mass concentrations and the δ13C-WSOC values in the Episode 1 indicate that WSOC is subject to a substantial photochemical aging during the air mass transport. In the Episode 2, the decline of the δ13C-WSOC is accompanied by the increase in the WSOC mass concentrations, which is associated with regional-transported biomass burning emissions. In the Episode 3, heavier isotope (13C) is exclusively enriched in total carbon (TC) compares to WSOC aerosols. This suggests that water-insoluble carbon may contain 13C-enriched components such as dust carbonate which is supported by the enhanced Ca2+ concentrations and air mass trajectories analysis. The present study provides a novel method to determine stable carbon isotope composition of WSOC and it offers a great potential to better understand the source emission, the atmospheric aging and the secondary production of water soluble organic aerosols.
Analysis of Sulfate Aerosols over Austria: A Case Study
Authors: Talianu Camelia , Seibert Petra
Published: December 2018

Abstract. An increase of the sulfate aerosols observed in the period 01–06 Apr 2014 over Austria is analyzed using in situ measurements at an Austrian air quality background station, lidar measurements at the closest EARLINET stations around Austria, CAMS near-real-time data and particle dispersion modelling using FLEXPART, a Lagrangian transport model. In-situ measurement of SO2, PM2.5, PM10 and O3 were performed at the air quality background station Pillersdorf, Austria (EMEP station AT30, 48°43' N, 15°55' E). A CAMS aerosol mixing ratios analysis for Pillersdorf and the lidar stations Leipzig, Munich, Garmisch, Bucharest indicates the presence of an event of aerosol transport, with sulfate and dust as principal components. For the sulfate layers identified at Pillersdorf from the CAMS analysis, backward and forward trajectory analyses were performed, associating lidar stations to the trajectories. The lidar measurements for the period corresponding to trajectory overpass of associated stations were analyzed, obtaining the aerosol layers, the optical properties and the aerosol types. The potential sources of transported aerosols were determined for Pillersdorf and the lidar stations using the source-receptor sensitivity computed with FLEXPART, combined with MACCity source inventory. A comparative analysis for Pillersdorf and the trajectory-associated lidar stations showed consistent aerosol layers, optical properties and types, and potential sources. A complex pattern of contributions to sulfate over Austria was found in this paper. For the lower layers (below 2000 m) of sulfate, it was found that the Central Europe was the main source of sulfate. Medium to smaller contributions come from sources in Eastern Europe, the Northwest Africa and Eastern US. For the middle-altitude layers (between 2000 m and 5000 m), sources from Central Europe (Northern Italy, Serbia, Hungary) contribute with similar emissions. Northwest Africa and Eastern US have also important contributions. For the high-altitude layers (above 5000 m), the main contributions come from Northwest Africa, but sources from Southern and Eastern US contribute also significantly. No contributions from Europe are seen for these layers. The methodology used in this paper can be used as a general tool to correlate measurements at in situ stations and EARLINET lidar stations around these in situ stations.
Characteristics of the tropical tropopause inversion layer using high-resolution temperature profiles retrieved from COSMIC GNSS Radio Occultation
Authors: Noersomadi Noersomadi , Tsuda Toshitaka , Fujiwara Masatomo
Published: December 2018

Abstract. Using COSMIC GNSS Radio Occultation (RO) observations from January 2007 to December 2016, we retrieved temperature profiles with 0.1 km vertical resolution in the upper troposphere and lower stratosphere (UTLS). We investigated the global distribution of static stability (N2) and the characteristics of the tropopause inversion layer (TIL) in the tropics, where a large change in temperature gradient occurs associated with sharp variations of N2. We show the variations of the mean N2 profiles in conventional height coordinates as well as in coordinates relative to both the Lapse Rate Tropopause (LRT) and the Cold Point Tropopause (CPT). When the N2 profiles are averaged relative to CPT height, there is a very thin ( +0.5 K) in the PO, warmer SSTs in the MC and PO produce more active deep convection that tends to force the air upward to the tropopause layer and increase the temperature gradient there. The intra-seasonal variation in S-ab* during slow and fast episodes of the Madden–Julian Oscillation (MJO) demonstrates that eastward propagation of positive S-ab* is associated with organized deep convection. This suggests that convective activity in the tropics is a major control on variations in tropopause sharpness at intra-seasonal to interannual time-scales.
Retrieval of aerosol microphysical and optical properties over land using a multimode approach
Authors: Fu Guangliang , Hasekamp Otto
Published: December 2018

Abstract. Polarimeter retrievals can provide detailed and accurate information on
aerosol microphysical and optical properties. The SRON aerosol algorithm is
one of the few retrieval approaches that can fully exploit this information.
The algorithm core is a two-mode retrieval in which effective radius
(reff), effective variance (veff), refractive index,
and column number are retrieved for each mode; the fraction of spheres for the
coarse mode and an aerosol layer height are also retrieved. Further, land and ocean properties
are retrieved simultaneously with the aerosol properties. In this
contribution, we extend the SRON aerosol algorithm by implementing a
multimode approach in which each mode has fixed reff and
veff. In this way the algorithm obtains more flexibility in
describing the aerosol size distribution and avoids the high nonlinear
dependence of the forward model on the aerosol size parameters. Conversely, the approach depends on the choice of the modes. We compare the performances of multimode retrievals (varying the number of
modes from 2 to 10) with those based on the original (parametric) two-mode
approach. Experiments with both synthetic measurements and real measurements
(PARASOL satellite level-1 data of intensity and polarization) are conducted.
The synthetic data experiments show that multimode retrievals are good
alternatives to the parametric two-mode approach. It is found that for
multimode approaches, with five modes the retrieval results can already be good
for most parameters. The real data experiments (validated with AERONET data)
show that, for the aerosol optical thickness (AOT), multimode approaches
achieve higher accuracy than the parametric two-mode approach. For single
scattering albedo (SSA), both approaches have similar performances.

Abstract. Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) is a widely used measurement technique for the detection of a variety of atmospheric trace gases. Using inverse modelling, the observation of trace gas column densities along different lines of sight enables the retrieval of aerosol and trace gas vertical profiles in the atmospheric boundary layer using appropriate retrieval algorithms. In this study, the ability of eight profile retrieval algorithms to reconstruct vertical profiles is assessed on the basis of synthetic measurements. Five of the algorithms are based on the optimal estimation method, two on parametrised approaches, and one using an analytical approach without involving any radiative transfer modelling. The synthetic measurements consist of the median of simulated slant column densities of O4 at 360 nm and 477 nm, as well as of HCHO at 343 nm and NO2 at 477 nm, from seven datasets simulated by five different radiative transfer models. Simulations are performed for a combination of 10 trace gas and 11 aerosol profiles, as well as 11 elevation angles, 3 solar 10 zenith and 3 relative azimuth angles. Overall, the results from the different algorithms show moderate to good performance for the retrieval of vertical profiles, surface concentrations and total columns. Except for some outliers, the root mean squares difference between true and retrieved state ranges between (0:05–0:1) km1 for aerosol extinction, and (2:5–5:0) × 1010 molec/cm3 for HCHO and NO2 concentrations.
Shifts in organic sulfur cycling and microbiome composition in the red-tide causing dinoflagellate Alexandrium minutum during a simulated marine heat wave
Authors: Deschaseaux Elisabeth , O'Brien James , Siboni Nachshon , Petrou Katherina , Seymour Justin R.
Published: December 2018

Abstract. The biogenic sulfur compounds dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP) and dimethylsulfoxide (DMSO) are produced and transformed by diverse populations of marine microorganisms and have substantial physiological, ecological and biogeochemical importance spanning organism to global scales. Understanding the production and transformation dynamics of these compounds under shifting environmental conditions is important for predicting their roles in a changing ocean. Here, we report the physiological and biochemical response of Alexandrium minutum, a dinoflagellate with the highest reported intracellular DMSP content, exposed to a 6 day increase in temperature mimicking coastal marine heatwave conditions (+4 °C and +12 °C). Under mild temperature increases (+4 °C), A. minutum growth was enhanced, with no measurable physiological stress response. However, under an acute increase in temperature (+12 °C), A. minutum growth declined, photosynthetic efficiency (FV/FM) was impaired, and enhanced oxidative stress was observed. These physiological responses were accompanied by increased DMS and DMSO concentrations followed by decreased DMSP concentrations. At this higher temperature, we observed a cascading stress response in A. minutum, which was initiated 6 h after the start of the experiment by a spike in DMS and DMSO concentrations and a rapid decrease in FV/FM. This was followed by an increase in reactive oxygen species (ROS) and an abrupt decline in DMS and DMSO on day 2 of the experiment. A subsequent decrease in DMSP coupled with a decline in the growth rate of both A. minutum and its associated total bacterial assemblage coincided with a shift in the composition of the A. minutum microbiome. Specifically, an increase in the relative abundance of OTUs matching the genus Oceanicaulis (17.0 %), Phycisphaeraceae SM1A02 (8.8 %) and Balneola (4.9 %) as well as a decreased relative abundance of Maribacter (24.4 %), Marinoscillum (4.7 %) and Seohaeicola (2.7 %), were primarily responsible for differences in microbiome structure observed between temperature treatments. These shifts in microbiome structure are likely to have been driven by either the changing physiological state of A. minutum cells, shifts in biogenic sulfur concentrations, or a combination of both. We suggest that these results point to the significant effect of heatwaves on the physiology, growth and microbiome composition of the red-tide causing dinoflagellate A. minutum, as well as potential implications for biogenic sulfur cycling processes and marine DMS emissions.
Sensitivity of atmospheric CO2 to regional variability in particulate organic matter remineralization depths
Authors: Wilson Jamie D. , Barker Stephen , Edwards Neil R. , Holden Philip B. , Ridgwell Andy
Published: December 2018

Abstract. The concentration of CO2 in the atmosphere is sensitive to changes in the depth at which sinking particulate organic matter is remineralised: often described as a change in the exponent "b" of the Martin curve. Sediment trap observations from deep and intermediate depths suggest there is a spatially heterogeneous pattern of b, particularly varying with latitude, but disagree over the exact spatial patterns. Here we use a biogeochemical model of the phosphorus cycle coupled with a steady-state representation of ocean circulation to explore the sensitivity of preformed phosphate and atmospheric CO2 to spatial variability in remineralisation depths. A Latin hypercube sampling method is used to simultaneously vary the Martin curve indepedently within 15 different regions, as a basis for a regression-based analysis used to derive a quantitative measure of sensitivity. Approximately 30 % of the sensitivity of atmospheric CO2 to changes in remineralisation depths is driven by changes in the Subantarctic region (36° S to 60° S), simliar in magnitude to the Pacific basin despite the much smaller area and lower productivity. Overall, the absolute magnitude of sensitivity is controlled by export production but the relative spatial patterns in sensitivity are predominantly constrained by ocean circulation pathways. The high sensitivity in the Subantarctic regions is driven by a combination of high export production and the high connectivity of these regions to regions important for the export of preformed nutrients such as the Southern Ocean and North Atlantic. Overall, regionally varying remineralisation depths contribute to variability in CO2 of between ±5–15 ppm relative to a global mean change in remineralisation depth. Future changes in the environmental and ecological drivers of remineralisation, such as temperature and ocean acidification, are expected to be most significant in the high latitudes where CO2 sensitivity to remineralisation is also highest. The importance of ocean circulation pathways to the high sensitivity in Subantarctic regions also has significance for past climates given the importance of circulation changes in the Southern Ocean.
A large increase in the carbon inventory of the land biosphere since the Last Glacial Maximum: constraints from multi-proxy data
Authors: Jeltsch-Thömmes Aurich , Battaglia Gianna , Cartapanis Olivier , Jaccard Samuel L. , Joos Fortunat
Published: December 2018

Abstract. Atmospheric CO2 increased by about 90 ppm across the transition from the Last Glacial Maximum (LGM) to the end of the preindustrial (PI) period. The contribution of changes in land carbon stocks to this increase remains uncertain. Estimates of the PI-LGM difference in land biosphere carbon inventory (∆land) range from −400 to +1,500 GtC, based on upscaling of scarce paleo soil carbon or pollen data. A perhaps more reliable approach infers ∆land from reconstructions of the stable carbon isotope ratio in the ocean and atmosphere assuming isotopic mass balance with recent studies yielding ∆land values of about 300–400 GtC. Surprisingly, however, earlier studies considered a mass balance for the ocean–atmosphere–land biosphere system only. Thereby, these studies neglect carbon exchange with sediments, weathering-burial flux imbalances, and the influence of the deglacial reorganization on the isotopic budgets. We show this neglect to significantly bias low deglacial ∆land in simulations using the Bern3D Earth System Model of Intermediate Complexity v.2.0s. We constrain ∆land to ∼ 850 GtC (median estimate; 450 to 1250 GtC 1σ range) by using reconstructed changes in atmospheric δ13C, marine δ13C, deep Pacific carbonate ion concentration, and atmospheric CO2 as observational targets in a Monte Carlo ensemble with half a million members. Sensitivities of the target variables to changes in individual deglacial carbon cycle processes are established from factorial simulations over the past 21,000 years with the Bern3D model. These are used in the Monte Carlo ensemble and provide forcing–response relationships for future model–model and model–data comparisons. Uncertainties in the estimate of ∆land remain considerable due to model and proxy data uncertainties. Yet, it is likely that ∆land is larger than 450 GtC and highly unlikely that the carbon inventory in the land biosphere was larger for the LGM than during the recent preindustrial period.

O presente trabalho objetivou quantificar os efeitos da tigmomorfogênese induzida por flexões caulinares na fase de rustificação de mudas de Pinus taeda L. sobre a partição da matéria seca e de carbono. Mudas de Pinus taeda com 22 cm de altura, produzidas em tubetes, foram submetidas a cinco intensidades de flexões caulinares (0, 5, 10, 20 e 40 flexões) realizadas diariamente, com o auxílio de um aparato mecânico, por 60 dias. Ao final, quantificou-se a área foliar e os incrementos na altura e no diâmetro do coleto. Posteriormente, determinaram-se os incrementos na massa de matéria seca de raízes e da parte aérea foram subdivididas em cinco componentes: raiz pivotante, raízes laterais, acículas, casca e lenho. Na matéria seca resultante, foi determinado o teor e conteúdo de carbono. O experimento seguiu o delineamento inteiramente ao acaso com quatro repetições. Os resultados foram submetidos à análise de regressão a 5% de probabilidade de erro. A tigmomorfogênese induzida por flexões caulinares resultou na redução do crescimento em altura, área foliar e matéria seca da parte aérea, mas, com até 20 flexões caulinares, promoveu o aumento da taxa de crescimento em diâmetro e matéria seca do sistema radicular. A alteração no crescimento primário e secundário foi resultante da redistribuição de carbono e do conteúdo de matéria seca no caule e no sistema radicular, principalmente em raízes laterais, através de redução de área foliar. Os resultados sugerem que em mudas perturbadas mecanicamenteo aumento em área foliar deixa de ser o dreno preferencial de carbono, predominando o crescimento de caule e sistema radicular.

Os modelos arquitetônicos ajudam a descrever o desenvolvimento e a organização das copas das árvores.Este conhecimento é essencial para a compreensão do desenvolvimento das árvores na floresta e podeajudar a entender a relação evolutiva entre táxons. O trabalho teve como objetivo verificar a riqueza demodelos arquitetônicos das espécies arbóreas de uma Floresta Estacional. Os dados foram coletados a partirde observações de campo e literatura especializada. Foram encontradas 53 espécies da flora arbórea de umaFloresta Estacional Subtropical de Santa Maria - RS, distribuídas em 45 gêneros e 28 das famílias. No total,13 diferentes modelos arquitetônicos foram reconhecidos. Os modelos com maior destaque foram Rauh,Troll, Scarrone, Roux e Massart. A complexidade arquitetural, refletida pelo elevado número de modelosdescritos, se deve ao desenvolvimento do dossel no remanescente estudado. O trabalho teve um caráterpioneiro e exploratório e deve fornecer um marco para novos estudos sobre arquitetura de plantas na regiãosubtropical do Brasil.

O objetivo do trabalho foi avaliar as condições nutricionais e de umidade de um solo cultivado com Eucalyptus benthamii no qual se incorporou biocarvão oriundo da pirólise rápida de uma mistura de madeiras de espécies nativas de Floresta Ombrófila Mista no preparo pré-plantio. O estudo foi desenvolvido em área experimental do Campus da Universidade Estadual do Centro-Oeste, localizada em Irati, Paraná. Foram utilizadas quatro doses de biocarvão, 0, 10, 20 e 40 Mg ha-1, com e sem adubação mineral de 340 Kg ha-1 de NPK com 14 Kg de N, 48 Kg de P2O5, 28 Kg de K2O no formulado 4-14-8, em delineamento em blocos ao acaso com quatro repetições. As mudas de Eucalyptus benthamii foram plantadas em espaçamento 3 por 2 metros e após 60 e 180 dias foram avaliados os seguintes atributos do solo: pH, carbono orgânico, teores de P, K, Ca, Mg, Al e a umidade do solo. A aplicação de 40 Mg ha-1 de biocarvão com e sem adubação de base ocasionou aumento do pH e nutrientes devido ao teor de cinzas na constituição do condicionador, e aumento da umidade do solo. A aplicação de biocarvão pode se tornar uma prática positiva com o objetivo de disponibilizar nutrientes para o desenvolvimento inicial da cultura. Entretanto, deve-se a avaliar o efeito da fertilidade, de acordo com as doses aplicadas, uma vez que a disponibilidade de nutrientes diminuiu ao longo do tempo acarretando a necessidade de adubações de cobertura, porém em quantidades menores.

Diferenças heteroespecíficas nas taxas de crescimento em altura, na produção de biomassa e na área foliar entre espécies coocorrentes são formas de medir a ocorrência de interações: facilitação ou competição. Com base no conceito mais amplo de facilitação, este tipo de interação positiva tem sido relatado para explicar a coocorrência de espécies em ambientes com alta limitação de recurso, a exemplo de climas árticos e áridos. O objetivo deste estudo foi avaliar se a facilitação pode favorecer o desenvolvimento inicial das populações de Mimosa caesalpiniifolia e Bauhinia cheilantha, duas espécies típicas da região da Caatinga, em casa de vegetação. As plântulas de Mimosa caesalpiniifolia Benth e de Bauhinia cheilantha (Bongard) foram cultivadas em vasos por 120 dias, nas proporções de 4:1; 3:2; 2:3; 1:4; 5:0; 0:5. Também foram realizadas avaliações na estrutura e em alguns teores (nitrogênio e fósforo) de nutrientes no solo e na folha das plântulas. Os resultados de crescimento, alocação de biomassa e concentrações de nitrogênio e fósforo nas folhas de Mimosa caesalpiniifolia foram influenciados positivamente com o aumento da densidade de indivíduos de Bauhinia cheilantha (Bongard) Steudel. No entanto, esta última espécie teve a menor taxa de crescimento de competição intraespecífica. Se for adotado o conceito mais amplo de facilitação, pode-se afirmar que houve interações positivas. Por se tratar de duas espécies de Fabaceae que podem apresentar associações com fungos micorrízicos e com bactérias diazotróficas, o principal nutriente limitante para o bom desempenho na coocorrência destas duas populações deverá ser o fósforo, pois não houve diferenças na quantidade de nitrogênio disponível no solo entre o início e o final do experimento.

A estratificação vertical, bem como vários parâmetros ecológicos de suma importância para a estrutura fitossociológica em florestas inequiâneas, reflete a quantidade de energia existente na floresta. O presente trabalho teve como objetivo avaliar o desempenho das metodologias usuais de caracterização da estratificação vertical em florestas. O levantamento de dados foi realizado em um fragmento de Floresta Estacional, no município de Vitória da Conquista, no campus da Universidade Estadual do Sudoeste da Bahia. A Posição Sociológica foi considerada como método padrão neste estudo. Os resultados obtidos foram comparados com outros seis diferentes métodos: IUFRO, Vega, Longhi, Calegário, Souza e Leite e Hasenauer. O desempenho dos métodos foi avaliado segundo o coeficiente “c”. Foram classificados pelo método padrão 954 indivíduos obtendo os seguintes resultados: 656 dominantes, 232 codominantes e 66 dominados. O coeficiente “c” mostrou-se eficiente na interpretação do desempenho dos métodos. O método da IUFRO apresentou o melhor desempenho em comparação ao Método da Posição Sociológica.

Este trabalho teve como objetivo realizar levantamento florístico e estrutural em um fragmento florestal urbano no Parque Ecológico Municipal José Milanese, no município de Criciúma, Santa Catarina, sul do Brasil, enfatizando a importância deste fragmento para a conservação de espécies ameaçadas. O levantamento consistiu na instalação de 100 parcelas contíguas de 10 × 10 m em Floresta Ombrófila Densa Submontana, sendo amostradas todas as espécies arborescentes com diâmetro à altura do peito (DAP) ≥ 5 cm. Foram registradas 137 espécies, sendo Myrtaceae a família mais rica. Cryptocarya moschata Nees & Mart. apresentou o maior valor de importância, principalmente pelo maior diâmetro de seus caules, seguida por Psychotria vellosiana Benth., Myrcia pubipetala Miq. e Guatteria australis A.St.-Hil., evidenciando a possibilidade de suas utilizações em programas de restauração ecológica em fragmentos florestais da região. Conclui-se que o fragmento estudado apresenta elevada riqueza específica, quando comparado com outros na região, tornando-o uma importante fonte de propágulos para áreas adjacentes. Além disso, o conhecimento produzido a partir deste estudo poderá fornecer alternativas de uso e manejo em áreas similares, ou mesmo, ambientes florestais alterados, de forma geral.

No Brasil, o Sistema Integrado de Diagnose e Recomendação (DRIS), já vem sendo muito utilizado como ferramenta de manejo nutricional em povoamentos de Eucalyptus e, atualmente são raros os estudos realizados com Pinus. Assim, objetivou-se realizar uma avaliação nutricional pelo sistema DRIS em um povoamento de Pinus taeda L., aos 19 meses de idade, plantado em Cambissolo na região dos Campos de Cima da Serra, RS. Foram usadas 64 doses de adubação, pela técnica do confundimento, para três fatores, com quatro níveis, distribuídos em quatro blocos, com doses de N (Ureia), P2O5 (Superfosfato triplo) e K2O (Cloreto de potássio). Foram coletadas três amostras compostas de acículas em cada um dos tratamentos (cada amostra formada por três árvores), determinando-se os teores médios de N, P, K, Ca e Mg. Para o cálculo das funções DRIS, foi usada a fórmula f = (R - r) / s, em que: f = valor da função para a relação (X/Y) entre os teores de dois nutrientes; R = valor da relação dual (X/Y); r = valor médio das relações duais (X/Y); s = desvio-padrão das relações duais (X/Y). A avaliação nutricional pelo DRIS indicou o N e o Ca como os nutrientes mais limitantes ao crescimento das plantas de Pinus taeda, aos 19 meses de idade, com a seguinte ordem de limitação: N = Ca > Mg > K > P; os teores ótimos estimados de N, P, K, Ca e Mg, pelo método do nível crítico gráfico, foram de 14,6; 1,6; 8,7; 2,6 e 0,8 g kg-1 respectivamente, indicando boas condições nutricionais das plantas de Pinus taeda.
