1. Bryophyte richness of soil islands on rocky outcrops is not driven by island size or habitat heterogeneity
ABSTRACT The species-area relationship (SAR) is one of the oldest and most studied ecological models, having even served as the foundation of the Theory of Island Biogeography. Nevertheless, the relative importance of habitat heterogeneity to SAR remains poorly understood. Our aim was to test the relative importance of habitat heterogeneity to the SAR of bry

2. Diversidade de macrófitas aquáticas em áreas úmidas do Parque Nacional da Lagoa do Peixe, Rio Grande do Sul
The Lagoa do Peixe National Park is an important conservation unity, aiming to protect the wetlands, one of the most endangered type of ecosystem in the world. In Southern Brazil around 90% of the wetlands were already lost. The protected ecosystems in the park are ernationally important for biodiversity conservation and it is the unique Ramsar site in South

3. Ilhas do litoral norte do estado de São Paulo: paisagem e conservação / Ilhas do litoral norte do estado de São Paulo: paisagem e conservação
To achieve more precise models of conservation units, it´s needed to consider the importance of development of knowledge of the insular dynamics. The main goal of the study was to evaluate the relationship between the types of vegetation found in eight island of northern coast of Sao Paulo state, it´s relationship as well structural features like area, sha

4. Species-distance relation for birds of the Solomon Archipelago, and the paradox of the great speciators
For scattered remote islands and for likely forms of immigration and extinction curves, the equilibrium theory of island biogeography leads to the prediction [unk]2 log S/[unk]A[unk]D > 0, where S is the number of species on an island, A island area, and D island distance from the colonization source. This prediction is confirmed for birds of the Solomon Arc

5. Immigration and extinction probabilities for individual species: relation to incidence functions and species colonization curves.
We develop a dynamic model of island biogeography based on immigration and extinction probabilities of individual species rather than on the usual biogeographic parameters of the number of species immigrating or going extinct per unit time. In the real world, these probabilities vary enormously among species, and three field studies suggest lognormal distrib

6. Colonization of the Krakatau Islands by vertebrates: equilibrium, succession, and possible delayed extinction.
MacArthur and Wilson [MacArthur, R. H. & Wilson, E. O. (1967) The Theory of Island Biogeography (Princeton Univ. Press, Princeton, NJ)] used the rate of recolonization of the Krakatau Islands (sterilized in the cataclysmic 1883 eruption) by birds and vascular plants to test their equilibrium model of immigration and extinction processes on islands. Working w

7. Biogeography of Tongan birds before and after human impact.
Bones deposited in caves show that, before the arrival of humans, at least 27 species of land birds lived on the Tongan island of 'Eua, where 13 indigenous species live today. Six of these 13 species were recorded from pre-human strata; three others probably occurred on 'Eua in pre-human times but were not in the fossil sample; and four others probably colon

8. Microbial Biogeography along an Estuarine Salinity Gradient: Combined Influences of Bacterial Growth and Residence Time
Shifts in bacterioplankton community composition along the salinity gradient of the Parker River estuary and Plum Island Sound, in northeastern Massachusetts, were related to residence time and bacterial community doubling time in spring, summer, and fall seasons. Bacterial community composition was characterized with denaturing gradient gel electrophoresis

9. Riding the ice age El Niño? Pacific biogeography and evolution of Metrosideros subg. Metrosideros (Myrtaceae) inferred from nuclear ribosomal DNA
Metrosideros subg. Metrosideros (Myrtaceae) comprises ≈26 species distributed widely across the Pacific basin. They occur on the ancient Gondwanan landmasses of New Zealand and New Caledonia, as well as on the volcanic islands of the remote Pacific, from Melanesia to tropical Polynesia and the Bonin Island. Phylogenetic analysis based on nuclear ribosomal
