Coccidioidomycosis is endemic in the US Southwest; histoplasmosis occurs in the East and Central states. Suggests environmental relationships with these diseases both caused by soil fungi. - (DWG)
socio-ecological relationships between Finns and lakes, rivers, and marshes-mires. First, the 'engine' of endemic time-space research, land use, and occupancy documentation, is explored in the Finnish context. Then two catchment areas, Kokemäenjoki
in Western Finland and Vuoksi in Eastern Finland, provide cases which illustrate both past endemic time-spaces and surviving aspects of cultural readings of lakes and rivers. . As industrial uses of catchment areas, zoning, and environmental permitting
exclude endemic readings inherent on the land and waterscapes, solutions are explored through mapping, along with its limitations, as a form bridging the gap between local realities and resource extraction.
The paper presents an analysis of the geographical distribution of endemic terrestrial vertebrates. A detailed evaluation was carried out for the mammalian class (Mammalia). All endemic species were divided into two categories : euendemic
and subendemic. The article presents an algorithm for analysis of the endemicity in the ramaining three classes of vertebrates : amphibians (Amphibia), reptiles (Reptilia) and birds (Aves). Treated as a preliminary phase to the wider elaboration are tables making
data comparisons for the number of endemics in each class of vertebrates. Statistical evaluation of the geographical units was based on the present of mammalian endemics. It proved possible to separate out some groups of units as regards similarity

and historical factors on species distribution and endemism. Species richness and the percentage of island endemic species as well as similarity indices for island comparisons were calculated for all species groups. The pattern of species richness is best
explained by island elevation. A similar pattern is detected for the percentage of single island endemics (pSIE), a factor associated with speciation. Thus, the AA. conclude that correlations between species richness and pSIE, identified in previous studies
The present fauna of the Tatra includes more than 20 subspecies and one species endemic to the Tatra; over 20 endemic to the Carpathians; 12 glacial relics; and two Tertiary relics. More than 75 % of Tatra vertebrates are placed under protection

the Quaternary period, covered by windblown sand in the form of linear desert dunes. These findings have implications for Pleistocene refugia in Africa and may explain both the relative paucity and high degree of endemism observed among African biota.
The avifauna of three oceanic islands of the Revillagigedo archipelago in the eastern Pacific Ocean consists of 14 endemic landbird taxa and 3 recent continental colonists. This study analyzes the origin, aerography of continental relatives
, ecological characteristics, and role of immigration and extinction factors as regulators of the islands'species. The endemic nature of the pristine avifauna is interpreted as an indication of high stability over thousands of years. The A. wishes to assess
The concept of biodiversity arose in the context of, and has remained firmly wedded to, concerns over the loss of the natural environment and its contents. Species richness, endemism, disparity measures and functional diversity are considered.
Author gives a short overview about the vegetation history of Hungary during the last 7-8000 years. A brief account is given about the decreasing amount of endemic woodland areas as a consequence of modern forestry. - (JS)
This study reports on the role volcanic tepra play on soil moisture conservation at Haleakala's crater and on the concomitant significance such layers have for the distribution and survival of the Haleakala silversword, a plant endemic to the arid
Brief ecological description of the Dakata valley, a granitic mountainous area in the Harerge region. It is an elephant sanctuary believed to contain most of the last 300 individuals of the endemic subspecies, Loxondonta africana orleansi. Somali
Five vegetation belts (lower montane, upper montane, dwarf pine, alpine and subnival) are described. Many endemics occur in the flora that has more than 1,000 vascular plant species. - (DWG)
