From a standpoint of phytosociological research, little is known about the phytocoenosis found on the volcanoes of Central America. This paper analyses the distribution of the vegetation on the volcano of San Pedro in terms of its species-richness, composition, structure and abundance, and the possible relationships between these components and the...
Antecedentes: La subcuenca Sayula localizada al centro-sur del estado de Jalisco, presenta un complejo paisaje conformado por diferentes comunidades vegetales a lo largo de un gradiente altitudinal. Pese a que existen diferentes trabajos del área, éstos no han abordado la distribución de la vegetación a lo largo de dicho gradiente, ni su interpreta...
Background:
seasonally dry tropical forests are considered critical and important ecosystems because they harbor exceptional biological diversity. Mexico lacks sound phytosociological studies of Seasonally Dry Tropical Forest and Michoacán is no exception. The present study may be regarded the first phytosociological in most of the Mexican pacific...
Antecedentes y Objetivos:
El límite superior del bosque es un ecosistema que alberga comunidades herbáceas y forestales con singular presencia de endemismos y con una función relevante en la captación, recarga y transporte de agua, lo que los define como nodos de provisión de bienes y servicios ambientales. Lo anterior es de particular significado...
Eucalyptus plantations have been established in many areas of the world due to their fast growth and profitability. In NW Spain, Eucalyptus plantations now cover a larger area than native forests. Although Eucalyptus plantations have been shown to affect biodiversity, relatively few studies have compared their effect on multiple taxonomic groups an...

The considered area is above the altitude of 1800 m included in the physiographical province of SMO, which entirely belongs to Tro...
Octopus stinkhorn, native from Tasmania, was introduced in Europe in the early twenty century. Thus in
Spain the species has been known since 1979, from The Basque Country (Guipúzcoa) and soon it began
to be cited towards of the Iberian Peninsula. In 1993 was published the presence of this fungus in Galicia.
After 25 years of the first Galician rec...
The vegetation belts on the slopes of the Sierra de Catorce and surrounding areas in the southern Chihuahuan Desert (State of San Luis Potosi, Mexico) were recognized. The major units of vegetation were studied from a phytosociological point of view and bioclimatic data results from weather stations were analysed and extrapolated. The Tropical Xeri...
