ABSTRACT
Kellicottia bostoniensis (Rousselet, 1908) es un rotífero planctónico, nativo de Norte América, pero reportado en Europa, Asia y hasta el momento en Sudamérica en Brasil y Argentina, donde ha sido señalado como especie invasora. En muestreos de zooplancton realizados en la zona fótica de diferentes ecosistemas colombianos (humedales urbanos, embalses y ríos) entre el 2019 y el 2022 se registraron individuos de K. bostoniensis. Este trabajo representa el primer reporte para Colombia y el norte de Sudamérica expandiendo su rango de distribución en el continente. Los especímenes analizados muestran las características morfológicas y morfométricas típicas de la especie K. bostoniensis y una distribución en un amplio rango de condiciones ambientales, como ha sido reportado en otras regiones. Se evidencia su potencial invasor y la posibilidad de que su rango de distribución se expanda hacia otras cuencas y ecosistemas colombianos, así como otros países de Sur América.
Kellicottia bostoniensis (Rousselet, 1908) is a planktonic rotifer, native from North America, but reported in Europe, Asia and South American countries such as Brazil and Argentina, where is registered as invasive species. In zooplankton sampling carried out in the photic zone of different Colombian ecosystems (urban wetlands, reservoirs and rivers) between 2019 and 2022, individuals belonging to this species were recorded. This work is the first report in both Colombia and the North of South America, expanding its distribution range in the continent. The analyzed specimens show the typical morphological and morphometric characteristics of the K. bostoniensis species and a distribution in a wide range of environmental conditions, as it has been reported in other regions. Its invasive potential is evidenced and the possibility that its distribution range expands towards other basins and ecosystems in Colombia and other countries of South America.
ABSTRACT
Objective:To enumerate the diversity of important medicinal plants used traditionally by the local populace in biodiversity rich and temperate Himalayan ranges of Bandipora district, Jammu and Kashmir, India. Methods:Methods used to explore the plants with medicinal value and to record associated ethnomedicinal knowledge included semi-structured interviews, focus group discussions and walk-in-the-woods with local knowledgeable persons, traditional practitioners called“Bhoeris”and tribals (Gujjars and Bakkerwals). Results:During plant exploration in this floristically rich Himalayan region, a very interesting and less-known species of the genus Prenanthes L., (Asteraceae) was recorded. On examination, the species was identified as Prenanthes violaefolia Decne., which represents a first report from Kashmir Himalaya, India. Conclusions: Prenanthes violaefolia could serve as an important source of new potent compounds provided that it is subjected to thorough phytochemical and pharmacological investigations.

ABSTRACT
Durante o período de 2005-2006 foram estudados os macroinvertebrados associados ao sistema radicular de Eichhornia crassipes (Mart.) Solms, 1883 na represa Chalons de Santiago de Cuba. A larva de Neoneura maria (Scudder, 1866), endêmica de Cuba, registrada para os três Setores da ilha, foi capturada constituindo o primeiro registro para a Província de Santiago de Cuba.
During the period 2005-2006 the macroinvertebrates associated with the root system of Eichhornia crassipes (Mart.) Solms, 1883 were studied in the overflow Chalons dam in Santiago de Cuba. The larva of Neoneura maria (Scudder, 1866), endemic for Cuba, reported to the three Sectors of the island, was collected and constitute the first report for the Província de Santiago de Cuba.
