Aim: The purpose of the study was to assess the degree of floristic differentiation between tropical dry forest (TDF) and savanna occurring in a single landscape. This comparison provides information on the responses of ...

El bosque tropical caducifolio es uno de los ecosistemas más característicos del estado de Oaxaca (sur de México). Se estima que este ecosistema ocupó alrededor de 30% del territorio estatal antes de la acción humana. La ...

The slash-and-burn agriculture practiced across tropical dry regions results in the elimination of native vegetation. Upon fi eld abandonment, the seed bank becomes a potentially important mechanism of natural regeneration ...

Se describe e ilustra Encyclia × nizanburyi, una notoespecie nueva la cual sólo se conoce de la región de Nizanda, en la vertiente del Pacífico del Istmo de Tehuantepec, en el estado de Oaxaca, México. Se discute el posible ...

Among the many explanations for the large biological diversity of Mexico is that it is the result of the contact between the Nearctic and Neotropical biotas; however, this contact-related explanation is not fully satisfactory ...

The magnitude of the biological differentiation between natural savannas and pastures (anthropogenic grasslands) coexisting in a single landscape, in terms of their floristic composition and community structure, was studied ...

Mechanistic models of community assembly state that biotic and abiotic filters constrain species establishment through selection on their functional traits. Predicting this assembly process is hampered because few studies ...

The heterogeneity of xerophytic vegetation developing on limestone outcrops immersed in a tropical deciduous forest matrix was studied in Nizanda (S Mexico). The study units comprised three clearly distinct communities ...
