1. Dinâmica ambiental holocênica (vegetação, clima e nível relativo marinho) baseada em estudos interdisciplinares de alta resolução, no litoral norte do estado do Espírito Santo / Holocene environmental dynamics (vegetation, climate and relative sea level) based on high resolution interdisciplinary studies, at northern coast of Espírito Santo state
Com base em um estudo interdisciplinar, os objetivos deste trabalho foram: estudar a dinâmica da vegetação e do nível relativo marinho e inferir o clima, durante o Holoceno, na região nordeste do estado do Espírito Santo. Para tanto foram analisados: (i) vegetação atual (caracterização botânica e delta13C e delta15N); (ii) matéria-orgânica do so

2. Paleoclimate and Amerindians: Evidence from stable isotopes and atmospheric circulation
Two Amerindian demographic shifts are attributed to climate change in the northwest plains of North America: at ≈11,000 calendar years before present (yr BP), Amerindian culture apparently split into foothills–mountains vs. plains biomes; and from 8,000–5,000 yr BP, scarce archaeological sites on the open plains suggest emigration during xeric “

3. Reconciling paleodistribution models and comparative phylogeography in the Wet Tropics rainforest land snail Gnarosophia bellendenkerensis (Brazier 1875)
Comparative phylogeography has proved useful for investigating biological responses to past climate change and is strongest when combined with extrinsic hypotheses derived from the fossil record or geology. However, the rarity of species with sufficient, spatially explicit fossil evidence restricts the application of this method. Here, we develop an alternat
