    During the main COVID-19 global pandemic lockdown period of 2020 an impromptu set of pollination ecologists came together via social media and personal contacts to carry out standardised surveys of the flower visits and plants in gardens. The surveys involved 67 rural, suburban and urban gardens, of various sizes, ranging from 61.18° North in Norway to 37.96° South in Australia, resulting in a data set of 25,174 rows, with each row being a unique interaction record for that date/site/plant species, and comprising almost 47,000 visits to flowers, as well as records of flowers that were not visited by pollinators, for over 1,000 species and varieties belonging to more than 460genera and 96plant families. The more than 650 species of flower visitors belong to 12 orders of invertebrates and four of vertebrates. In this first publication from the project, we present a brief description of the data and make it freely available for any researchers to use in the future, the only restriction being that they cite this paper in the first instance. The data generated from these global surveys will provide scientific evidence to help us understand the role that private gardens (in urban, rural and suburban areas) can play in conserving insect pollinators and identify management actions to enhance their potential

    Indicadores da condição hídrica do solo foram avaliados em um experimento de campo, em Eldorado do Sul, RS, Brasil. Utilizou-se um Argissolo Vermelho Distrófico típico, utilizado durante oito anos em sistema plantio direto e preparo convencional. A cultivar de soja Fepagro Rs(-1)0, foi semeada em 20/11/2003, com 0,40 m entre fileiras e 300 mil plantas por hectare, em tratamentos irrigados e não irrigados. Variáveis do sistema solo-planta-atmosfera foram monitoradas e a ênfase neste trabalho visou aos períodos secos; monitoraram-se, também, variações no potencial matricial da água no solo, entre 0,075 e 1,20 m de profundidade. Verificou-se que o tempo de secagem do solo foi mais prolongado nas parcelas sob plantio direto indicando, em períodos de secagem, potenciais matriciais menos negativos, menores temperaturas máximas e menor amplitude térmica que em preparo convencional; também, a altura de plantas e o índice de área foliar apontaram que maiores estoques de água em plantio direto podem reduzir efeitos do déficit hídrico em soja cultivada neste sistema de manejo. Esses indicadores reforçam a importância da análise integrada de respostas das culturas em um enfoque sistêmico de manejo de solo e água.<br>Soil water condition indicators were assessed in a field experiment conducted in Eldorado do Sul, Brazil. The Paleudult soil of the experimental area has been managed during eight years under no-tillage and conventional tillage. Soy bean cultivar Fepagro Rs(-1)0 was sown on November 20, 2003, with 0.40 m of row spacing and 300,000 plants ha-1, with and without irrigation. Variables of soil, plant and atmosphere were monitored with emphasis during drought periods. Variations of the matrix water potential were monitored from 0.075 to 1.20 m of soil depth. A regular delay was observed in the soil drying process in no-tilled plots, in particular during drought periods, indicating higher water storage in no-tillage than in conventional tillage. Higher matrix water potential, lower maximum temperature and smaller thermal amplitude were observed in no-tillage, in comparison to the conventional tillage. Indirect indicators, such as plant height and leaf area index, were in accordance to the higher water storage in no-tilled plots, due to reductions of water deficit in plants. This set of indicators demonstrated the importance of evaluating crop responses in a systemic approach to soil and water management

    La Empresa Colombiana de Petróleos, Ecopetrol S.A., tiene dentro de sus objetivos, el desarrollo de actividades relacionadas con la exploración, explotación, refinación, transporte, almacenamiento, distribución y comercialización de hidrocarburos, sus derivados y productos; la empresa está comprometida con apoyar y garantizar el desarrollo del país. Lo anterior, desde una cultura de cuidado con las personas y los entornos ecológicos, en donde realizan las diversas actividades. El departamento de Casanare, corresponde a una región que presenta zonas de montaña y de sabana, con una alta biodiversidad natural y a su vez, muy rico en petróleo, que son de gran importancia para el país. En el municipio de Aguazul, localizado en las estribaciones de la cordillera Oriental, se ubica el Centro de Producción de Fluidos de Cupiagua, considerado de gran transcendencia para esta región. En inmediaciones de este centro se localizan las veredas Cupiagua y El Triunfo, donde aún se registran bosques con una considerable riqueza florística y en las cuales, se desarrolló esta investigación, propuesta en el marco del convenio realizado con la Universidad Pedagógica y Tecnológica de Colombia y Ecopetrol, S.A. denominado 5211740 de 2012, y los proyectos “Rescate de individuos, mantenimiento y estudio de flora en veda, del sistema de transporte de hidrocarburos Cupiagua-Cusiana (Casanare, Colombia)” en cumplimiento a la Resolución 1349 de 2011, y el “Estudio, taxonomía, biología y conservación de plantas no vasculares en el bosque el Danubio, Aguazul” que da cumplimiento al Auto 151 del 24 de abril de 2014, del MADS”. Conscientes de la importancia de divulgar el conocimiento científico, generado a partir de las investigaciones realizadas en alianza estratégica con la Universidad Pedagógica y Tecnológica de Colombia, que es reconocida por su gran impacto académico, nos permitimos mostrar de una manera visual, los resultados producto del esfuerzo y conocimiento del equipo de investigadores, quienes trabajaron con Zamias, consideradas fósiles vivientes ya que existen desde la época de los dinosaurios; epífitas vasculares y no vasculares (briófitos y líquenes), que crecen sobre diferentes sustratos y generan condiciones microclimáticas que favorecen la vida para otros organismos; plantas vasculares, que embellecen el paisaje y mantienen especies de fauna y flora de interés ecológico para el equilibrio natural; a su vez, el trabajo comunitario con la Institución Educativa Cupiagua. Por lo anterior, Ecopetrol S.A., se permite presentar el libro “Flora de Aguazul: muestra de diversidad”, con el cual se aporta nuevo conocimiento y se resalta su beneficio en la conservación de nuestros recursos naturales
