Abstract.- Brief overview of the evolutionary drivers that lead to the emergence and survival of new species. The concept of species is also briefly reviewed. The origin of groups above the species level is also discussed.
Keywords.- Evolution; Adaptation; Speciation.
Abstract.- This article presents the concepts of population genetics that enable us to understand the dynamics of species evolution, particularly our beloved orchids, which are champions at adapting to environmental factors.
Keywords.- Evolution; selection; adaptation; genetics.
Abstract.- Myrmecophily is the association between ants and other organisms. These symbiotic relationships are varied and more or less exclusive or essential to the life of one or other of the partners. They are described here, with examples to illustrate the different associations.
Keywords.- Myrmecophily; ants; symbiosis.
Abstract.- This article looks at the differences between two modes of plant life, epiphytism and parasitism. Examples of both are detailed and particular attention is paid to the adaptations of epiphytic orchids.
Keywords.- epiphytism; evolution; habit; parasitism.
If you really want to find something precious that nobody else has ever seen before, or at least not scientifically documented as a new orchid species, it can pay off to study maps of remote areas in faraway countries. Peru has still a lot to offer in that regard. This country has been searched through for a couple of centuries by professional plant hunters, looking for just that unique plant that would bring a lot of fame and fortune for their employers.
