NUTRIENTES FOLIARES DE ESPÉCIES ARBÓREAS NA MATA ATLÂNTICA: EFEITO DO TAMANHO DO FRAGMENTO

http://dx.doi.org/10.5902/1980509818449The study was made in Atlantic forest fragments in the lowland region of the protected area of São João riverbasin, Rio de Janeiro state, Brazil. The aim of the study was to test the hypothesis that fragment size altersmacro-nutrients concentrations in leaves of the main tree species (Guarea guidonea e Cupania oblongifolia)in the area. Adult leaves of Guarea e Cupania were sampled in three small (23- 33 ha), three medium(130 - 155 ha) and three large (500 - 2300 ha) fragments. Carbon, N, Ca, Mg and K were determined.The results showed that, in general, the reduction of the fragment size did not affect the nutritional statusof the species studied. Nevertheless, the higher Mg concentrations in Cupania oblongifolia leaves in thesmall fragments (5.0±0.8 mg/g) compared with the medium (4.0±0.3 mg/g) and large (3.5±0.7 mg/g) onesindicated an effect of the reduction of the fragment area over this element.http://dx.doi.org/10.5902/1980509818449O presente estudo foi desenvolvido em fragmentos de Mata Atlântica na região de baixadas do Rio de Janeiro, inseridos na área de proteção da bacia do Rio São João. O objetivo deste estudo foi testar a hipótese de que o tamanho do fragmento altera a concentração de macronutrientes em folhas de duas das principais espécies arbóreas (Guarea guidonea e Cupania oblongifolia) ocorrentes nessa área. Folhas adultas de Guarea guidonea e Cupania oblongifolia foram coletadas em três fragmentos pequenos (23 - 33 ha), três médios (130 - 155 ha) e três grandes (500 - 2300 ha). Carbono, N, Ka, Ca e, Mg foram determinados. O tamanho do fragmento em geral não afetou o estado nutricional nas folhas das espécies estudadas. No entanto, a maior concentração de Mg em folhas de Cupania oblongifolia nos fragmentos menores (5,0±0,8 mg/g) em relação aos fragmentos médios (4,0±0,3 mg/g) e grandes (3,5±0,7 mg/g) indica um efeito do tamanho do fragmento sobre este elemento

Fine roots biomass in fragments of Atlantic Forest from Rio de Janeiro’s State

A escassez de estudos empíricos dos sistemas radiculares limita a precisão das predições relativas à economia de carbono, pois eles representam até 55% da biomassa florestal. Somente as raízes finas (diâmetro <2 mm) respondem por cerca de um terço da produção primária líquida dos ecossistemas terrestres. A hipótese de que a maior disponibilidade de água e nutrientes no solo reduz a alocação de biomassa nas raízes tem sido contestada na literatura cientifica tanto em relação às raízes finas (BRF) como a toda biomassa radicular. Avaliou-se aqui a correlação (Pearson) entre BRF e variáveis edáficas até 10 cm de profundidade em seis fragmentos florestais (48 amostras.fragmento.estação-1) na Baixada Litorânea Fluminense, nas estações de seca e de chuvas. Os solos apresentaram diferentes níveis de fertilidade. A BRF média geral foi de 641 g.m-2 (florestas similares = 140–1040 g.m-2). As médias de BRF obtidas no período chuvoso ou na várzea foram significativamente mais elevadas. Foram detectadas correlações positivas e significativas de BRF com Ca + Mg, K, P e N. Os resultados não respaldam a hipótese de redução da BRF em resposta ao aumento de água e nutrientes do solo.Palavras-chave: Fragmentação florestal; florestas tropicais; solos florestais e trópico úmido. AbstractFine roots biomass in fragments of Atlantic Forest from Rio de Janeiro’s State. Despite the relative importance of roots, which may reach up to 55% of forests biomass, there is a lack of empirical data from tropical regions. Just fine roots biomass (FRB; < 2 mm) represent around one third of the net primary production of terrestrial ecosystems. The general acceptance that higher levels of water and nutrients decrease biomass allocation in roots has been contested in the literature. Six forest fragments along the Coastal Plains of Rio de Janeiro’ State were taken to assess correlations (Pearson’s) between FRB and soil variables within a depth of 10 cm. Soil and root samples were collected (N=48.fragment-1.season-1) in wet and dry seasons. Forest soils showed different fertility levels. Overall means of FRB was 641 g.m-2 (other tropical forests = 140 - 1040 g.m-2). Humid season presented the highest average of FRB and also the hydromorphic soil of the sample. Positive and significant correlationn between Ca + Mg, K, P, N with FRB were found. The hypothesis of FRB decrease in response to availability decrease of resources is not supported by obtained results.Keywords: Forest soils; forest fragmentation; humid tropics; forest soils.Despite the relative importance of roots, which may reach up to 55% of forests biomass, there is a lack of empirical data from tropical regions.

Potential economic impact assessment for cattle parasites in Mexico. Review

Las pérdidas económicas causadas por parásitos del bovino en México se calcularon anualmente. Los principales factores considerados para esta evaluación incluyeron el número total de animales a riesgo, los posibles efectos dañinos del parasitismo sobre la producción de leche o ganancia de peso, y los decomisos de subproductos pecuarios. Las pérdidas económicas fueron estimadas en dólares americanos (US$) y se basaron en las pérdidas del rendimiento productivo de animales no tratados. Estas estimaciones reflejan los principales efectos de seis parásitos o grupos de parásitos sobre la producción bovina. El impacto económico potencial (millones de dólares) fue: nematodos gastrointestinales US$ 445.10; coccidias (Eimeria spp.) US$23.78; duelas del hígado (Fasciola hepatica) US$ 130.91; garrapatas (Rhipicephalus microplus) US$573.61; mosca de los cuernos (Haematobia irritans) US$ 231.67; y mosca de los establos (Stomoxys calcitrans) US$6.79. En general, las pérdidas anuales causadas por los seis principales parásitos del bovino en México se estimaron en US$ 1.41 mil millones. Considerando que la población bovina nacional en 2013 fue de 32.40 millones de bovinos, la pérdida anual estimada fue de US$43.57 por animal. Se hace mención de las limitaciones que tienen el uso de algunas referencias para las estimaciones, particularmente cuando se extrapolan situaciones locales a una escala nacional. Sin embargo, el resultado general obtenido en este estudio demuestra la magnitud e importancia del parasitismo en el ganado de México y los desafíos para maximizar la rentabilidad de la industria ganadera sin recurrir al uso de estrategias de control integrado sustentable de parásitos. ABSTRACT Here, economic losses caused by cattle parasites in Mexico were estimated on an annual basis. The main factors taken into consideration for this assessment included the total number of animals at risk, potential detrimental effects of parasitism on milk production or weight gain, and records of condemnation on livestock byproducts. Estimates in US dollars (US$) were based on reported yield losses in untreated animals. These estimates reflect the major effects on cattle productivity of six parasites, or parasite group. The potential economic impact (US$millions) was: gastrointestinal nematodes US$ 445.10; coccidia (Eimeria spp.) US$23.78; liver fluke (Fasciola hepatica) US$ 130.91; cattle tick (Rhipicephalus microplus) US$573.61; horn fly (Haematobia irritans) US$ 231.67; and stable fly (Stomoxys calcitrans) US$6.79. Overall, the yearly economic loss due to the six major parasites of cattle in Mexico was estimated to be US$ 1.41 billion. Considering that the national cattle herd registered in 2013 included 32.40 million head, the estimated yearly loss per head was US$ 43.57. The limitations of some of the baseline studies used to develop these estimates, particularly when extrapolated from local situations to a national scale, are acknowledged. However, the general picture obtained from the present effort demonstrates the magnitude and importance of cattle parasitism in Mexico and the challenges to maximize profitability by the livestock industry without adapting sustainable and integrated parasite control strategies

Expanding tropical forest monitoring into Dry Forests: The DRYFLOR protocol for permanent plots

This is the final version. Available on open access from Wiley via the DOI in this recordSocietal Impact Statement Understanding of tropical forests has been revolutionized by monitoring in permanent plots. Data from global plot networks have transformed our knowledge of forests’ diversity, function, contribution to global biogeochemical cycles, and sensitivity to climate change. Monitoring has thus far been concentrated in rain forests. Despite increasing appreciation of their threatened status, biodiversity, and importance to the global carbon cycle, monitoring in tropical dry forests is still in its infancy. We provide a protocol for permanent monitoring plots in tropical dry forests. Expanding monitoring into dry biomes is critical for overcoming the linked challenges of climate change, land use change, and the biodiversity crisis.Newton FundNatural Environment Research Council (NERC)Fundação de Amparo à Pesquisa do Estado de São PauloCYTE

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Taking the pulse of Earth's tropical forests using networks of highly distributed plots

Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of funding agencies. Here we show how a global community is responding to the challenges of tropical ecosystem research with diverse teams measuring forests tree-by-tree in thousands of long-term plots. We review the major scientific discoveries of this work and show how this process is changing tropical forest science. Our core approach involves linking long-term grassroots initiatives with standardized protocols and data management to generate robust scaled-up results. By connecting tropical researchers and elevating their status, our Social Research Network model recognises the key role of the data originator in scientific discovery. Conceived in 1999 with RAINFOR (South America), our permanent plot networks have been adapted to Africa (AfriTRON) and Southeast Asia (T-FORCES) and widely emulated worldwide. Now these multiple initiatives are integrated via ForestPlots.net cyber-infrastructure, linking colleagues from 54 countries across 24 plot networks. Collectively these are transforming understanding of tropical forests and their biospheric role. Together we have discovered how, where and why forest carbon and biodiversity are responding to climate change, and how they feedback on it. This long-term pan-tropical collaboration has revealed a large long-term carbon sink and its trends, as well as making clear which drivers are most important, which forest processes are affected, where they are changing, what the lags are, and the likely future responses of tropical forests as the climate continues to change. By leveraging a remarkably old technology, plot networks are sparking a very modern revolution in tropical forest science. In the future, humanity can benefit greatly by nurturing the grassroots communities now collectively capable of generating unique, long-term understanding of Earth's most precious forests.Additional co-authors: Susan Laurance, William Laurance, Francoise Yoko Ishida, Andrew Marshall, Catherine Waite, Hannsjoerg Woell, Jean-Francois Bastin, Marijn Bauters, Hans Beeckman, Pfascal Boeckx, Jan Bogaert, Charles De Canniere, Thales de Haulleville, Jean-Louis Doucet, Olivier Hardy, Wannes Hubau, Elizabeth Kearsley, Hans Verbeeck, Jason Vleminckx, Steven W.
