Habitat structure and neighbor linear features influence more carabid functional diversity in olive groves than the farming system

The effects of land-use management and environmental features at different scales on carabid beetle diversity and trait structure were assessed across olive groves in northeastern Portugal. We selected organic and integrated olive groves that were distinct in terms of specific management practices, local linear features and landscape configurations. Besides the management intensification levels, differences in carabid diversity and community traits were mainly due to local habitat and ecological linear structures at a finer spatial scale. Carabid community traits related to disturbance, namely traits of body size and species dispersal ability, responded to land-use intensity and particular olive grove features were influencing diversity patterns. Within the olive grove patches, larger and brachypterous species were associated to plots with more dense vegetation cover while macropterous and small-sized species were more associated to open areas. Also, larger carabid species benefitted from higher patch size heterogeneity within the landscape mosaics. Our findings indicate that the effects of farming system is contingent on the specific management practices, local and linear features present in agroecosystems such as olive groves. Particularly, the influence of local features on carabid diversity patterns and community traits linked to dispersal and movement may be crucial in maintaining pest control at a landscape scale.The authors would like to thank all farmers who allowed our access to their olive groves.

Zoneamento agroecológico para a região de Ribeirão Preto utilizando um sistema de informações geográficas.

Objetivando contribuir com a metodologia de identificação de potencialidades de uso das terras, este trabalho apresenta uma proposta de zoneamento agroecológico da quadrícula de Ribeirão Preto, SP, localizada entre as coordenadas de 21o00'S a 21o30'S e 47o30'W a 48o00'W, com base em características de solo, relevo e clima, utilizando-se de um Sistema de Informações Geográficas. Para caracterizar o regime térmico-hídrico da área utilizou-se os dados de temperatura do ar e de chuva, de 22 localidades, referentes ao período de 1967 a 1996. De acordo com os critérios adotados, quanto a capacidade de uso das terras, o zoneamento identificou seis unidades de utilização da área: agricultura (I); agricultura (II); agricultura (III); pecuária; agrossilvicultura e preservação. As principais conclusões referentes à área de estudo foram: o regime térmico-hídrico é praticamente homogêneo, a vocação dominante é para agricultura (I) representando aproximadamente 191.118 hectares, correspondentes a 66,3% da área e cerca de 82,5% das terras possuem vocação para agropecuária e 10,4% devem ser preservadas ou utilizadas seguindo técnicas conservacionistas

DETECCIÓN, CARACTERIZACIÓN SEROLÓGICA Y ANTIBIOGRAMAS DEEscherichia coli AISLADAS DE CARNE DE TERNERA (BABILLA) ENTERA Y PICADA

Los brotes de Enfermedades Transmisibles por Alimentos (ETA) representan una preocupación para las industrias alimentarias y los organismos de salud pública. Las cepas patógenas de Escherichia coli están comúnmente presentes en el trato intestinal de los animales, lo que favorece la contaminación durante el sacrificio o durante un procesamiento inadecuado de la canal. La importancia que la carne tiene en la alimentación humana junto con la necesidad de ofrecer un alimento inocuo e incapaz de transmitir enfermedades, incitaron el desarrollo de este estudio, que tiene por objetivos, detectar, caracterizar los serogrupos y realizar los antibiogramas de E. coli. aisladas de 30 muestras de carne de ternera (babilla) comercializadas en mercados y carnicerías de Río de Janeiro, Brasil. Se emplearon 15 muestras de carne entera y 15 de carne picada (en el propio establecimiento). Se utilizaron diferentes metodologías para la confirmación bioquímica y serológicamente de las colonias aisladas. Una vez identificados los serogrupos, se testó su susceptibilidad a diferentes antibióticos. De las muestras analizadas, el 100% resultaron contaminadas con coliformes totales y en cinco (16,7%) de ellas, no se detectaron coliformes fecales. En carne entera, los recuentos de coliformes totales oscilaron de 4,0x103 a 1,1x106 y E.coli de 0 a 2,4x103 mientras que en carne picada oscilaron de 4,4x103 a 2,5x107 y 0 a 3,0x105, respectivamente. Con relación a la metodología empleada,el segundo método demostró ser más eficiente que el tercer método, ya que presentó un mayornúmero de colonias confirmadas. Utilizando el segundo método, se aislaron 52 cepas de E. colienteropatogénica (EPEC), ocho cepas de E. coli enteroinvasiva (EIEC) y una cepa de E. coli enterohemorrágica (EHEC). Las cepas de E. coli aisladas y tipificadas como patógenas presentaron un gran espectro de resistencia a los antibióticos testados, principalmente a ampicilina (11,32%), cefalotina (11,11%) y amicacina (10,06%). La presencia de serogrupos de E. coli en las muestras confirman la necesidad de implantar los programas de Buenas Practicas de Fabricac ión (BPF), Procedimientos Patrón de Higiene Operacional (PPHO) y Análisis de Peligros y Puntos Críticos de Control (APPCC), lo que diminuiría el riesgo para el consumidor.Palabras clave: Escherichia coli, carne de ternera entera y picada, antibiograma.Escherichia coli, whole and ground beef, antibiogram

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results

AVASUS’ Contributions to Promoting Lifelong Learning in Health: Toward Achieving the SDGs and Strengthening Global Health Security

The Virtual Learning Environment of the Brazilian Health System (AVASUS) was developed by the Laboratory for Technological Innovation in Health (LAIS) and the Secretariat of Distance Education (SEDIS) at the Federal University of Rio Grande do Norte (UFRN) in partnership with Brazil’s Ministry of Health (MoH). AVASUS provides open educational resources in the health field and has emerged as the third largest platform for massive health education globally, with more than one million students. Among the various learning pathways AVASUS offers, some specifically focus on meeting the educational needs to address public health emergencies and overlooked health contexts. The main argument in this study is that technology-mediated lifelong learning in health is an effective strategy for achieving the Sustainable Development Goals (SDGs) of the 2030 Agenda. This chapter analyzes the pathways related to COVID-19, syphilis, and prison health, focusing on the contributions towards achieving SDGs 3, 4, 5, 10, 11, 16, and 17 and fulfilling the Global Health Security Agenda. Our analysis revealed two key findings. Lifelong learning in health (i) prompts decision-making on public health policies and (ii) contributes towards implementing the SDGs. Ultimately, AVASUS should be recognized as a tool to improve health services and support policy-making
