Living reptiles are easy to recognize with the naked eye, however, they are difficult to define due to the morphological heterogeneity and phylogenetic complexity of the group. The objective of this research is to determine the species of reptiles found in the semi-deciduous forest located in the town of Buena Vista, municipality of Remedios, province of Villa Clara, Cuba. For the development of the research, the following capture methods were used: capture by means of a rod with a sliding knot, capture by hand, by means of a terrestrial trap with a diversion fence in combination with pit (boat) and cylinder traps, opportunistic collection, visual encounter, limited time collection and capture by means of thick leashes. Site visits were conducted from April 2022 to April 2023, covering all seasons of the year. As a result of the field work in situ, 19 species of reptiles belonging to fou...

ABSTRACT Dichotomous keys are resources or tools that researchers, teachers or other personnel linked to the study of biological sciences use for the determination of different species of organisms, through the comparison of two excluding characters. The objective of the research presented is aimed at making a dichotomous key in electronic format for the identification of virtual shells of marine gastropods present in the malacological fauna of Cuba, and in correspondence with the teaching-learning process of General Zoology I, in the career of Bachelor in Education. Biology, at the Central University "Marta Abreu" of Las Villas, Villa Clara, Cuba. In the research, different methods were used to collect information and process it in its dialectic interrelation, which allowed identifying the detected insufficiencies and formulating the solution. The information for the diagnosis is obtain...
