The 2020 glaciation

My wish for 2020 is that an imaginary glaciation erodes all evil so we can start again from scratch. I know it is silly but it is nothing more than a wish, although a very intense one

See you (or not) in the postglacial…

Biodiversity of the Lost World

The book “Biodiversity of Pantepui, the Pristine Lost World of the Neotropical Guiana Highlands”, edited by V. Rull, T. Vegas-Vilarrúbia, O. Huber and C Señaris, is already published in Paperback and eBook formats. See the Elsevier website.

This book provides the most updated and comprehensive knowledge on the biota, origin, and evolution of the Pantepui biogeographical province. It synthesizes historical information and recent discoveries, covering the main biogeographic patterns, evolutionary trends, and conservational efforts. The book also explores what makes Pantepui a unique natural laboratory to study the origin and evolution of Neotropical biodiversity under the influence of only natural drivers. It discusses the organisms living in Pantepui, including algae, plants, several groups of invertebrates, birds, amphibians, reptiles, and mammals. The latter portion of the book delves into the effects of human activity and global warming on Pantepui, and current conservational efforts to combat these threats. The book is an important resource for researchers in ecology, biogeography, evolution, and conservation, who want to understand the biodiversity and natural history of this region, and how to help conserve and protect the Guiana Highlands from environmental and human damages.

Quaternary Ecology, Evolution and Biogeography

The book “Quaternary Ecology, Evolution and Biogeography” by V. Rull, which will be issued in March 2020, can already be pre-ordered at the Elsevier website.

This book is an introduction to the study of the ecological and evolutionary processes that have shaped our present biosphere under the influence of glacial-interglacial cycles. The book reviews the climactic changes that have occurred during the last million years, along with the responses of organisms and ecosystems, and offers an understanding of the evolutionary origin of extant biodiversity, its biogeographical patterns and the composition of modern ecological communities. In addition, it explores human evolution and the influence of our activities on the biosphere, especially in the last millennia, and offers the latest information on how studying the past can contribute to our understanding of present climate issues for a better future. The book is intended for a wide audience, including researchers and students in natural sciences.

Contents:

  • Climate: Continuous variability and impact on the earth system
  • Organisms: Adaption, extinction and biogeographical reorganizations
  • Biodiversity: Diversification or impoverishment?
  • Communities: Adjustments, innovations and revolutions
  • Humans: Settlement and humanization of the planet
  • The future: Natural cycles and human interference

Neotropical Diversification: Patterns and Processes

The book “Neotropical Diversification: Patterns and Processes”, edited by V. Rull and A. C. Carnaval, which will be issued in March 2020, can already be pre-ordered at the Springer website in Hardcover and eBook versions.

This book provides a comprehensive overview of the patterns of biodiversity in various Neotropical ecosystems, as well as a discussion on their historical biogeographies and underlying diversification processes. All chapters were written by prominent researchers in the fields of tropical biology, molecular ecology, climatology, paleoecology, and geography, producing an outstanding collection of essays, synthetic analyses, and novel investigations that describe and improve our understanding of the biodiversity of this unique region. With chapters on the Amazon and Caribbean forests, the Atlantic rainforests, the Andes, the Cerrado savannas, the Caatinga drylands, the Chaco, and Mesoamerica – along with broad taxonomic coverage – this book summarizes a wide range of hypotheses, views, and methods concerning the processes and mechanisms of neotropical diversification. The range of perspectives presented makes the book a truly comprehensive, state-of-the-art publication on the topic.

Reference: Rull, V. & Carnaval, A.C. (eds.). 2020. Neotropical Diversification: Patterns and Processes. Springer, Berlin. ISBN 978-3-030-31166-7 (Hardcover) and 978-3-030-31167-4 (eBook).

The Earth is flat for climate modelers

Did you know that? Modelers don’t stop surprising us!!!

If you find this hard to believe, read the paper by Michael J. Prather and Juno C. Hsu, from the University of California, which has recently been published in the Proceedings of the National Academy of Science USA.

See the reference and the significance statement below the flat Earth

flat_earth

Reference

Prather, M.J. & Hsu, J.C. 2019. A round earth for climate models. Proc. Natl. Acad. Sci. USA, 116: 19330-19335.

Significance

Early climate and weather models, constrained by computing resources, made numerical approximations on modeling the real world. One process, the radiative transfer of sunlight through the atmosphere, has always been a costly component. As computational ability expanded, these models added resolution, processes, and numerical methods to reduce errors and become the Earth system models that we use today. While many of the original approximations have since been improved, one—that the Earth’s surface and atmosphere are locally flat—remains in current models. Correcting from flat to spherical atmospheres leads to regionally differential solar heating at rates comparable to the climate forcing by greenhouse. gases and aerosols. In addition, spherical atmospheres change how we evaluate the aerosol direct radiative forcing.

Lost World’s biodiversity uncovered

The book about the biodiversity of the Conan Doyle’s Lost World will be issued in a couple of weeks. The title is “Biodiversity of Pantepui, the Pristine Lost World of the Neotropical Guiana Highlands” and is published by Elsevier-Academic Press.

Pantepui is a remote archipelago of sky islands with unique biodiversity and endemism patterns that constitutes one of the few pristine regions remaining in the planet. The biodiversity and ecosystems of this lost world have been generated by purely natural ecological and evolutionary processes, which turns Pantepui into a natural laboratory to study the origin and evolution of Neotropical biomes. The following video provides an outlook of the Pantepui landscape.

The book is subdivided into four parts, namely (i) general aspects, (ii) the photosynthetic world, (iii) animal diversity and (iv) biodiversity conservation, and the following chapters:

  1. Definition and characterization of the Pantepui biogeographical province
  2. Climatic and ecological history of Pantepui and surrounding areas
  3. Pantepui as a dynamic biogeographical concept
  4. Origin and evolution on the Pantepui biota
  5. Algae
  6. Vascular plants and bryophytes
  7. Plant communities
  8. Aquatic insects
  9. Butterflies
  10. Scorpions
  11. Land snails
  12. Amphibians and reptiles
  13. Birds
  14. Mammals
  15. Vertebrate parasites
  16. Conservation of Pantepui: between complex emergency and climate change
  17. Pantepui and global warming

The front matter can be freely downloaded and the book can be purchased here.
