Th e investigation presents a malacological survey in heights of Sierra Morena, Corralillo, Villa Clara, Cuba. A total of 69 samples were collected from October 2015 until June 2016, georeferenced in a map (1:10000) and processed with numeric classifi cation techniques. A total of 26 species were identifi ed. Of the 26 species, one is endemic to the area and another is new to science. Established methodology was used for the collection of mollusks. Th ree species collected in the study area constitute potential vectors of organism pathogens to humans. It was possible to correlate the distribution of this species with the anthropogenic landscape, based on that information a potential protected area is proposed. Th e results of this study are useful to develop activities geared to environmental education.

Invasive species are animals, plants, or other organisms transported and introduced by humans in places outside their natural distribution area and that have managed to establish and disperse in the new region, where they are harmful. The objective of the research was aimed to propose a system of workshops to contribute to the knowledge of Invasive Exotic Species (IES), and their undesirable effects on vulnerable Cuban ecosystems and in particular on the bird species Molothrus bonariensis (Gmelin, 1789), 8th-graduate students of the Basic Urban Secondary School "Fe del Valle". For the effective development of this research, methods of information gathering and processing were used in their dialectic interrelation, which allowed us to verify fy existing deficiencies in terms of knowledge of IES and their undesirable effects. The research represents a novel way of appropriating new knowled...

La investigación presenta una encuesta malacológica terrestre de las Alturas de Sierra Morena, Corralillo, Villa Clara, Cuba. Se tomaron un total de 69 muestras desde octubre de 2015 hasta junio de 2016, las cuales fueron enmarcadas en un mapa de 1:10 000 y procesadas con técnicas de clasifi cación numérica. Se detectaron un total de 26 especies de moluscos terrestres, de las cuales una entra en la categoría de endémica local y otra de nueva para la ciencia, por lo queda pendiente su clasifi cación. Se utilizaron los métodos convencionales para la colecta de los moluscos. Tres especies presentes en la zona de estudio constituyen vectores potenciales de organismos patógenos de enfermedades al hombre. Se relacionó las áreas de distribución de las especies con las condiciones antrópicas, por lo que se propone una zona por sus valores como área a preservar. Se concluye que la ...

Fieldwork favors the interaction of schoolchildren with nature and the community, making it an activity with suffi cient potential for the formation of values.

Taxidermy is an encounter between science, technique and art in favor of education and scientific culture. The objective of this research work is to propose a complementary course of basic taxidermy for the students of the second year of the Primary Teachers' career of the Pedagogical School "Manuel Ascunce Domenech", located in the city of Santa Clara, province of Villa Clara, Cuba. In order to carry out the research, the methods of information gathering and processing of the information gathered in their dialectic interrelation were used, within the latter, observation and survey stand out. It was found that in this institution there are no natural objects, namely animals preserved in liquid or dissected, which facilitate a better understanding when using them as a means of teaching the contents related to the teaching-learning process of Biology, and the students and teachers have ins...

Se determinó la artropofauna cavernícola en una cueva de calor de la Reserva Ecológica «Mogotes de Jumagua», en el Municipio Sagua la Grande, provincia Villa Clara, Cuba. La artropofauna fue colectada o utilizando los métodos convencionales. La temperatura máxima del aire fue de 33,6 C y la humedad relativa del aire fue del 90%, lo que ubica a esta cueva dentro de la categoría de “cueva de calor”. Se ofrecen apuntes sobre la presencia de 11 especies de artropotroglofauna: Periplaneta americana (Linné, 1758) (Blattodea: Blattidae); (2) Byrsotria fumigata (Guérin-Méneville, 1857) (Blattodea: Blaberidae); (3) Carcinophora americana (Beauvois, 1817) (Dermaptera: Anisolabididae); (4) Pyrophorus noctilucus (Linné, 1758) (Coleoptera: Elateridae; (5) Alphitobius diaperinus (Panzer, 1797) (Coleoptera: Tenebrionidae); (6) Antricola sp.

The investigative work presents a system of actions to carry out fi eld work with an integrative character and with an ecosystem approach and confronting climate change in the Bachelor of Education career Biology-Geography in Cuba, to enhance the future professional performance of graduates, by promoting Environmental Education and sustainable development in the centers of this level of education for the terminal years in the selected fi eld practice polygons. The diagnosis was made to determine the diffi culties that affect fi eld work realization in an integrative way. To mitigate the diffi culties detected, the system of actions whose contribution to the theory is given in its conception is proposed where the interaction between its components allows fulfilling the social order exposed in the professional model. The components that make up the system are: a theoretical block made...

The research is based on a malacological survey of freshwater molluscs of veterinary medical importance present in the Villa Clara province, Cuba. Methods associated with socio-cultural research were combined with methods and techniques used in laboratory and field work. In this sense, methods of the theoretical level (historical-logical, analytical-synthetic, and inductive-deductive) and empirical level (the survey, interview and documentary analysis) were used. The methodology allowed to verify the existing deficiencies on the knowledge of the freshwater aquatic molluscs species of medical importance. The collection of freshwater molluscs was carried out manually, using a hand strainer with a 1 mm mesh opening and a 2 m long handle for 10 minutes in the water bodies. The novel aspect of this research is that students and teachers from different Urban Basic Secondary Schools (ESBU) of s...

An ecological study was carried out with the objective of evaluation of the ornithocenosis present in "Monte Ramonal" in the municipality of Santo Domingo, Villa Clara province, Cuba between December 2017 and April 2018. The plant formation where the studies were carried out was the semideciduous mesophilic forest, on a poorly drained soil. For the avifauna counts, a transect of approximately 800 meters long was taken. Given the characteristics of the vegetation, the area analyzed was 11,200m2 (approximately one hectare). We determined the systematic structure, guilds, species richness, similarity, dissimilarity, diversity, and fairness. A total of 34 species of birds belonging to 18 families and 9 orders were detected. The best represented order was Passeriformes with 10 families and 21 species. Of the total species reported, 4 genera (50%), 7 species (33.3%) and 16 subspecies (22.8%) a...

En esta investigación se realiza una evaluación de la ornitocenosis presente en “Monte Ramonal”, municipio de Santo Domingo, provincia Villa Clara, Cuba, en los meses de diciembre de 2017 y abril de 2018 respectivamente.
