Plants of the subfamily Amaryllidoideae are a source of unique and bioactive alkaloids called Amaryllidaceae alkaloids. The study of their anticancer potential has intensified in recent years. This work aims to locate and characterize the profile of cytotoxic alkaloids biosynthesized and stored in different tissues of Phaedranassa lehmannii Regel u...

La contaminación, resultado del crecimiento demográfico y actividades humanas, afecta la salud y el medio ambiente. En el Oriente antioqueño, el auge de la industria floricultora genera aguas residuales coloreadas, que podrían tratarse mediante fitorremediación con humedales artificiales, ofreciendo una alternativa eficaz y sostenible para abordar...
• Contextualización: La zona de transición acuático terrestre (ZTAT) en la planicie de inundación (llanura aluvial) Ramsar Ayapel (Colombia), permanece inundada más de la mitad de un año y su franja litoral genera una fuerte influencia en el ecosistema. Una aproximación a la caracterización espacial y temporal de esta zona es fundamental para un po...

Abstract: Weeds can have both positive and negative effects on agricultural environments. However , despite the growing interest in the eco...
Seeds have morphoanatomical characteristics that determine the survival of plants in different environments, and these are directly related to phenomena such as dormancy. Natural selection filters the plant communities that inhabit the different ecosystems of planet earth and their seed banks. This has direct implications for ecological restoration...
Weeds can have both positive and negative effects on agricultural environments. However, despite the growing interest in the ecology of weed communities in agricultural areas, few studies have been carried out in the northern region of the Andes of Colombia, where urban and agricultural expansion have gen-erated highly disturbed scenarios. The aim...
Seed dormancy is a key trait used around the world to help understand the ecological dynam- ics of plant species, however, in some ecosystems such as the Andean forests of Colombia, the identification of dormancy class remains poorly known. To address this, we described the morphology, anatomy and dormancy class of the seeds and fruits of 14 specie...
Los bancos de semillas como indicadores en los procesos de sucesión natural de los humedales del altiplano del Oriente antioqueño y su utilidad en la restauración ecológica
Background and Aims:
Thunbergia alata is one of the ten most problematic invasive plant species in Colombia. Its rapid colonization and adaptation to Andean forests have affected the composition and structure of indigenous plant communities. In this research, analysis of functional traits was carried out, generating new information that could expla...
En el presente trabajo se dan a conocer diferentes aspectos de la historia de vida de esta invasora, así como algunos lineamientos para su control y manejo. El primer capítulo contiene un recuento histórico, en el cual se muestra cual fue su movimiento a lo largo del continente hasta la llegada a nuestro territorio, basado en la cronología de los s...
Históricamente los campesinos del corregimiento de Santa Elena, Medellín han cultivado una gran diversidad de flores que desde el siglo XIX eran llevadas a la zona urbana de Medellín junto con otros productos agrícolas, los cuales se comercializaban en las diferentes calles de esta ciudad en plena etapa de crecimiento. De estos productos era sorpre...

Does anybody know a free software for the edition of science figures different from photoshop?
I am trying to make anatomical cuts of seeds of neotropical species. For this, I use a general protocol for plant tissues with some modifications. However, when I make the cuts in the microtome the paraffin sheets breake down.
Does anyone know of any specific protocol about fixation and embedding of plant seeds to obtain successful anatomical cuts or can someone give me some advices in this regard?
