Published: December 2020

Five Astragalus species (A. cicer, A. falcatus, A. galegiformis, A. glycyphyllos, and A. ponticus) grown at the M.M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine were investigated. Plant raw material was collected at different ontogenetic stages, including budding, flowering, and fruiting. After that, the content of ash, calcium, phosphorus, nitrogen, and photosynthetic pigments was analyzed and statistically processed.The content of ash varied from 3.12 to 5.22 %, calcium – from 0.31 to 0.91 %, phosphorus – from 0.07 to 0.14 %, and nitrogen – from 1.93 to 2.48 % depending on the stage of growth. The content of chlorophyll a varied from 0.901 to 2.475 mg/g FW (fresh weight), chlorophyll b – from 0.190 to 0.676 mg/g FW, and carotenoids – from 0.496 to 1.129 mg/g FW.Thus, the accumulation of ash and its components in the raw material of the investigated species depended on the period of growth and certain species. Content of photosynthetic pigments correlated with the content of phosphorus (r = 0.887–0.999) and with plant increment (r = 0.756–0.998) for all investigated species. Obtained data can be applied to analyze productivity and during the cultivation of these plants.
Short notice concerning the current conservation status of dark-barked birch taxa and the proposed changes to the next edition of the Red Book of Ukraine

Published: December 2020

Recently in Ukraine, there were many discussions about proposed changes to the next edition of the Red Book of Ukraine. Kingdom Plantae. In this short communication, we clarify one particular aspect within the discussions concerning the proposition to exclude dark-barked birch Betula obscura from the next edition of the Red Book of Ukraine. It is argued by the new research data obtained and published during last years, and which provide evidence that there is no reason to treat B. obscura as a separate species because it represents only one of at least two different dark-barked birch forms of two widely distributed birch species in Ukraine (B. pendula f. obscura and B. pubescens f. sibakademica), respectively. Therefore, the proposition to exclude B. obscura from the next edition of the Red Book of Ukraine is reasonable since it is aimed to protect plants on the species level only.

Hablar de emprendimiento es hacer, es crear y es impulsar aquella convicción que generará oportunidades de crecimiento y desarrollo, ya sea social o empresarial. Conocer las herramientas y alternativas que ofrece el emprendedurismo es valorar las posibilidades de crecer y consolidarse. Comunidades como Silicon Valley, Boston, Berlín, Tel Aviv, Londres y Boulder tardaron décadas en convertirse en ecosistemas de innovación y emprendimiento avanzados y sólidos. Sin embargo, las grandes ideas de negocios pueden venir y surgir de cualquier parte hoy en día. En la economía moderna, estos ecosistemas pueden crecer en cualquier lugar, cada comunidad tiene la oportunidad de convertirse en un ecosistema próspero. De hecho, muchos ya lo han hecho. La creación de estos ecosistemas está ganando impulso en muchas partes del mundo ya no sólo en Estados Unidos a medida que se reconocen sus beneficios; influyendo también en México quien está empezando a adoptar este mecanismo. Estos ecosistemas ayudan a impulsar la innovación, la creación de nuevas empresas, a lograr cambios sociales y ayudan a que las oportunidades de empleo crezcan. Naciones, ciudades, regiones, universidades y otros están colaborando para establecer ecosistemas de emprendimiento como un componente crítico. El concepto de ecosistema se toma de la biologi?a, donde se hace referencia a una comunidad de seres vivos y el medio natural en que viven. Donde los procesos vitales se relacionan entre si? y se desarrollan en funcio?n de los factores fi?sicos de un mismo ambiente. Respecto al emprendimiento, el concepto se adapta para referirse a un medio que facilite a las Startups, PyMEs y prácticamente cualquier tipo de empresa desarrollarse y crecer a sus máximas capacidades. Un medio donde existan o se creen políticas públicas acordes, acceso a diferentes fuentes de financiamiento, capacitación y educación continua, inversión privada y vinculación con los diferentes sectores económicos como cámaras y organizaciones de la sociedad civil y universidades.

Authors: Zacarías Alvarado José Rodolfo , Tovar Robles Clara Lourdes , Méndez Gallegos Santiago de Jesús , Magallanes Quintanar Rafael , Aquino Pérez Gildardo 
Published: December 2020

Dactylopius coccus es un insecto de importancia comercial como fuente de un colorante natural denominado ácido carmínico. Para su producción comercial en cautiverio, se ha promovido la cría en cladodios suspendidos a diferentes alturas, en un sistema denominado “nopaloteca”. Sin embargo, se desconoce si su calidad y rendimiento es uniforme en los diferentes niveles. El objetivo de este estudio fue determinar la influencia de la altura del nivel en una “nopaloteca” y el índice de cosecha en la concentración de ácido carmínico (CAC, %) y peso fresco (PF, g) de D. coccus. La crianza del insecto se realizó en una “nopaloteca” de madera (3x3 m), con cuatro niveles de altura (0.5, 1.0, 1.50 y 2 m). Durante el ciclo de cultivo se registró cada día la temperatura, la humedad relativa y la intensidad luminosa. Las hembras adultas se recolectaron en dos etapas del desarrollo: pre y postoviposición. La CAC más alta (19.2%) se obtuvo en 1.0 m de altura, aunque este nivel registró el PF más bajo con 3.5 g por cladodio, que expresa una correlación negativa entre la CAC y el PF. La recolecta en postoviposición generó una CAC superior (18.8%), aunque el PF se redujo. Tanto la humedad relativa (HR) como la iluminación total, pero principalmente la temperatura que incidió en cada nivel, influyeron en la calidad y el rendimiento de D. coccus, aunque de manera diferencial sobre ambos factores, lo cual indica la presencia de límites óptimos de desarrollo. Bajo las condiciones del estudio, el sistema de cría en “nopaloteca” produjo en promedio 4.5 g de cochinilla por cladodio y una CAC de 17.5%. Los niveles evaluados causaron diferencias en rendimiento y calidad, pero sus valores más altos se registraron en los niveles intermedios (1.0 y 1.5 m). El índice de cosecha recomendado para obtener mayor CAC fue la etapa de postoviposición.
