“…Mountainous areas are among the most diverse ecosystems on Earth (Orme et al 2005) and tropical mountain cloud forests are known for their high share of endemic plants and animals (Bruijnzeel 2001, Leo 1995, Kappelle and Brown 2001. Cloud forests have been reported to be very susceptible to changes in environmental conditions (Lawton et al 2001, Pounds et al 1999.…”

The Luquillo Mountains of northeastern Puerto Rico harbours important fractions of tropical montane cloud forests. Although it is well known that the frequent occurrence of dense fog is a common climatic characteristic of cloud forests around the world, it is poorly understood how fog processes shape and influence these ecosystems. Our study focuses on the physical characteristics of fog and quantifies the fogwater input to elfin cloud forest using direct eddy covariance net flux measurements during a 43-day period in 2002. We used an ultrasonic anemometerthermometer in combination with a size-resolving cloud droplet spectrometer capable of providing number counts in 40 droplet size classes at a rate of 12.5 times per second. Fog occurred during 85% of the time, and dense fog with a visibility <200 m persisted during 74% of the period. Fog droplet size depended linearly on liquid water content (r 2 =0.89) with a volumeweighted mean diameter of 13.8 µm. Due to the high frequency of occurrence of fog the total fogwater deposition measured with the eddy covariance method and corrected for condensation and advection effects in the persistent up-slope air flow, averaged 4.36 mm d −1 , rainfall during the same period was 28 mm d −1 . Thus, our estimates of the contribution of fogwater to the hydrological budget of elfin cloud forests is considerable and higher than in any other location for which comparable data exist but still not a very large component in the hydrological budget. For estimating fogwater fluxes for locations without detailed information about fog droplet distributions we provide simple empirical relationships using visibility data.

“…The cloud forest range of the spectacled bear in Perú's Oriental Andes contains 32% of that country's endemic birds, mammals, and anurans combined. The ratio of the number of endemic species per unit area is approximately 5.75 times greater in these cloud forests than it is in Perú's Amazonian forest (Leo 1993). Existing conservation units contain only a small fraction of Andean biodiversity.…”

“…The cloud forest above 1,500m in Perú where bears live contain an estimated 15% of vertebrates and vascular plants, and 32% of Perú's endemic species in only 5% of Perú's landmass. On a unit area basis that level of endemism is 5.75 times greater than it is in Perú's Amazonian forests (Leo 1993). Table 9.6.…”

“…For example, the spectacled bear's range in Río Abiseo NP in the northern central Andes (Figure 9.5) is home to 36 endemic vertebrates. This is 9% of Perú's endemic vertebrates (n=272) and 29% of those that live in Perú's montane forests (n=126, Leo 1993). Undisturbed parts of the range have the highest density bear populations found in Perú as evidenced by copious amounts of fresh spoor seen throughout the year.…”

INTRODUCTION Scope and geographical coverageThis extract of the PHYSIS database of the Institut Royal des Sciences Naturelles de Belgique offers a framework to organize in an ordered sequence, according to the same methodology as that used for the CORINE Biotopes Habitats of the European Cominunity typology (Devillers et al., 1991), the habitats of the South American realm. The geographical area covered encompasses South America and its nearshore islands, Trinidad and Tobago, Margarita, Aruba, Curaçao, Bonaire, Los Roques, Blanquilla and associated islands, the Galapagos Islands, Malpelo Island, the Juan Fernandes Islands, the San Felix archipelago, Fernando de Noronha, South Trinidad and the Martin Vas islands, St. Peter and St. Paul rocks, Easter Island and Sala y Gomez.Definitions and structure 1. Habitat.In the most common usage, a habitat is "the natural home of an animal or plant" (Collins English Dictionary), "the normal abode or locality of an animal or plant" (Chambers Twentieth Century Dictionary), or "the natural abode of a plant or animal" (Webster's New Collegiate Dictionary). Integrating these definitions over all species, for each of which the habitat is the sum of the abiotic enviromnent and of all other species present, a habitat can be defined as "a topographical expanse homogeneous in its physical and biotic components at the scale of the phenomenon studied" (Blondel, 1979(Blondel, , 1995. This is the defînition that has been adhered to in the CORINE Habitat typology and the Physis data-base. Thus, a habitat is a three-dimensional spatial entity that comprises at least one interface between air, water and ground spaces, it includes both the physical environment and the communities of plants and animals that occupy it, it is a fractal entity in that its définition depends on the scale at which it is considered. The conditions encountered by a given species are similar on the entire surface of the habitat, but not all characteristics of the habitat are ever assembled at any one point (Blondel, 1979(Blondel, , 1995. Scale.The définition of a habitat depends entirely on the scale at which it is considered (Blondel, 1979(Blondel, , 1995. Thus a steppe can be defined, as in the Physis Database, as a "formation dominated by medimn or tall perennial tuftforming grasses or suffrutescents, with lacunar ground cover, together with its associated therophyte communities". At a higher level of resolution it can be seen as a mosaic of habitats, bunches of tail perennial grasses on the one hand, bare surfaces temporarily supporting communities of therophytes on the other hand. At a lower level of resolution, the grass steppe and the steppe woods that dot it can be regarded as a single habitat, the wooded steppe. The level of resolution that has been used in the CORINE typology is that of the ecological requirements of small vertebrates, large invertebrates and vascular plants. A few units, clearly labelled, have been introduced to permit rendition by the use of single codes or combined codes of the ecological...
