ABSTRACT Estudios sobre los recursos vegetales en las provincias de El Oro, Loja y Zamora-Chinchipe. Ediciones Abya Yala, Quito. — Actualmente se reconoce al sur del Ecuador, como uno de los sitios más diversos de los Andes y de la Amazonía. Varios autores han intentado describir la vegetación existente, pero algunos tipos de vegetación, típicos de la región, no han sido incluidos o reconocidos. Aquí se describen 17 tipos de vegetación, adaptados a terminologías anteriormente probadas, distribuidos desde el Pacífi co hasta el alto río Marañón. Se incluye un breve análisis de su distribución, con sus principales elementos fl orísticos y aquellos que son característicos para cada tipo de vegetación. Abstract. Lozano C., P. E. 2002.

Balslev (eds.), Botánica Austroecuatoriana — Estudios sobre los recursos vegetales en las provincias de El Oro, Loja y Zamora-Chinchipe. Ediciones Abya Yala, Quito. — Southern Ecuador is known to be one of the most diverse places in the Andes and the Amazonian regions. Several attempts have been made by different authors to describe the existing vegetation but some vegetation types, typical of the region, have been left out or have been unrecognised. Seventeen vegetation types are here described and are named according to the different authors. They are distributed from the Pacifi c Ocean to the inner Marañon river. A brief analysis of their distribution is included as well as the main characteristic fl oristic elements for each of them.

    ABSTRACT: Distribution patterns of plant species endemic to Ecuador and adjacent parts of southern Colombia and northern Peru are analysed on the basis of information in the Flora of Ecuador. A total of 827 restricted-range species were found, many of which are known from extremely small areas, often only one or a few localities. A total of 27% of the species treated in the Flora of Ecuador are endemic to that country. The overall proportion of endemic and restricted-range species is greater in the Andes than in the lowland areas on either side of these mountains; particularly the southern Andes appears to be very rich in endemic species. Spatial analysis of distribution data results in the recognition of 15 floristic elements and 18 geographical endemism regions in Ecuador, the characteristics of which are discussed. Comparison with distribution patterns of restricted-range bird species show a general correspondence, with the main difference that birds tend to be more widely distributed than plants along the Andes. Comparison of the results with the location of national parks and other protected areas shows that the endemic floras in the northern and eastern parts of the country are much better protected than those of the southern and western parts.
