Opuntia fragilis (Nutt.) Haw. (Cactaceae) in the Bulgarian flora
Published in Acta Scientifica Naturalis
Opuntia fragilis (Nutt.) Haw. (Cactaceae) is the smallest and most cold-hardy species of genus Opuntia in North America. In Bulgaria it is grown as an ornamental plant, but in 2019 a population of this species was discovered by other researchers in natural habitats in Lozenska Mt (Western Bulgaria) at 630–660 m a.s.l. on an area (extent of occurren...
Stem transcriptome screen for selection in wild and cultivated pitahaya ( Selenicereus undatus) : an epiphytic cactus wi...
Published in PeerJ
Dragon fruit, pitahaya or pitaya are common names for the species in the Hylocereus group of Selenicereus that produce edible fruit. These Neotropical epiphytic cacti are considered promising underutilized crops and are currently cultivated around the world. The most important species, S. undatus , has been managed in the Maya domain for centuries ...
Estudios de los efectos del pH, densidad estomática, ácido-3-indolacéticoy ácido abscísico en cactáceas cultivadas in vi...
Crassulaceaeacid metabolism (MAC or CAM) generally takes place in plants that live in arid areas with little water availability. These plants are characterized by being succulent, having a waxy cuticle and carrying out photosynthesis in the stems. In this work several aspects of its metabolism in cacti in vitroand ex vitroare addressed. The variati...
Evolution of flower allometry and pigmentation in Mammillaria haageana (Cactaceae)
Published in BMC Plant Biology
BackgroundA puzzle in evolution is the understanding of how the environment might drive subtle phenotypic variation, and whether this variation is adaptive. Under the neutral evolutionary theory, subtle phenotypes are almost neutral with little adaptive value. To test this idea, we studied the infraspecific variation in flower shape and color in Ma...
Cereus hildmannianus (K.) Schum. (Cactaceae): Ethnomedical uses, phytochemistry and biological activities.
Published in Journal of ethnopharmacology
Cereus hildmannianus (K.) Schum. (syn. C. peruvianus) is a native medicinal plant in the Neotropical region. C. hildmannianus cladodes extracts are used in folk medicine for weight loss, reducing cholesterol, low-density lipoprotein (LDL) levels, as diuretic and cardiotonic, and to treat various diseases, including pulmonary disorders, rheumatism, ...

The traffic of flora and its derivatives is a lucrative business. Plant species marketed by criminal groups specializing in this illicit supply on the black market the demands of certain companies in the fields of gastronomy, pharmaceuticals, cosmetics, fashion and collecting, among others. Despite legislative actions, police, as claims, of the dif...
Quantitative and qualitative traits of carcass and meat of goats fed diets with cactus meal replacing corn
...Published in Tropical Animal Health and Production
The purpose of this study was to evaluate the quantitative and qualitative characteristics of the carcass and meat of goats fed diets containing cactus meal (pectin source) replacing corn (starch source). Twenty-eight goats with an average initial weight of 16 ± 2.02 kg were confined in a completely randomized design with four treatments (the repla...
On the most imbalanced orientation of a graph
Published in Journal of Combinatorial Optimization
We study the problem of orienting the edges of a graph such that the minimum over all the vertices of the absolute difference between the outdegree and the indegree of a vertex is maximized. We call this minimum the imbalance of the orientation, i.e. the higher it gets, the more imbalanced the orientation is. The studied problem is denoted by MAXIM...
