The past five years have seen the arrival and extremely rapid expansion of West Nile virus (WNV) in the Western Hemisphere. The rapid sweep across North America has permitted little time for developing knowledge of the virus's potential impacts on…

(3) the richness pattern is independent of the endemism pattern because the richest areas are the tropical humid lowlands, and (5) Mexico presents several insular intracontinental patterns, which are the product of the disjunct and heterogeneus distribution of xeric and…

and (ii) the derived state of the breeding (rather than winter) ecological niches of each species., The evolution of migration has long been considered complex and recent work has demonstrated additional complexity: some species follow the same ecological conditions throughout…

of the remaining 263 species, we arrived at a specieslevel identification for 242, and identified the remainder to genus (19) or family (2). The recent discovery of these ornithological texts and paintings offers a unique view of the history of…

Although some excellent articles about Lyell's work have been published, they do not explicitly deal with Lyell's biogeographical conceptions. The purpose of this paper is to analyse Lyell's biogeographical model in terms of its own internal structure. Lyell tried to…

sampling for a species close to the median of the distribution (Great Blackhawk Buteogallus urubitinga) was scattered and inappropriate for statistical analysis, Results suggest strongly that sampling of Mexican birds is incomplete, that continued scientific collecting is needed to complete…

Environmental assessments of regional development projects have been used in Mexico to determine where conflicts between conservation of biodiversity and resource extraction are likely to occur. Speciesrich areas have been acknowledged as a priority for conservation. However, biological information is…

There are three different uses of the term 'inoformation' in ordinary language: in the restricted sense, it means diverse types of material objects, such as data or documents ('information-as-thing'); alternatively, the term is used as in reference to the act…

The regime of floods and droughts in the Pantanal wetlands determines the distribution and abundance of the wildlife, vegetation and ecological processes. Cattle ranching and fisheries, the main economic activities in this floodplain, are extremely influenced by and depend on…

The bivalve Limnoperna fortunei (Dunker, 1857), also called golden mussel, is native to Asia but becoming dispersed around the world. The golden mussel resembles the invasive dreissenid bivalves in many respects, and although much less studied it evidently has broader…
