Are we in the Anthropozoic era?

The manuscript entitled: The Anthropozoic era revisited, by V. Rull, has been accepted for publication in the journal Lethaia. The abstract is provided below.

Abstract: This paper explains in some detail the poorly known proposal of Stoppani (1873) regarding the Anthropozoic era, whose beginning was defined by the first traces of human presence on Earth. This author set the stratigraphic bases for the definition of the “human era”, but the proposal had two main weaknesses: the dismissal of biological evolution and the lack of an absolute chronology. Further developments in radiometric/palaeomagnetic dating and the elucidation of the main trends and timing of human evolution have provided the necessary information to update the original Anthropocene proposal in chronological terms, maintaining Stoppani’s original definition and stratigraphic markers. This updated proposal follows the rules of the International Stratigraphic Guide and situates the beginning of the Anthropozoic era at the beginning of the Quaternary, the time at which the first human fossils, corresponding to the first species of the genus Homo, and corresponding cultural manifestations have been identified and dated. Therefore, the new Anthropozoic era would follow the Cenozoic era, which ended with the Neogene period. Defined in this way, the Quaternary period and its Pleistocene and Holocene epochs would be situated in the new Anthropozoic era. The main strengths and weaknesses of the updated Anthropozoic version are discussed. It is suggested that the updated Anthropozoic proposal might be fully elaborated to evaluate whether it should be submitted to the International Commission on Stratigraphy and the International Union of Geological Sciences for its eventual formalization.

The three dimensions of human impact on island vegetation

The manuscript entitled: Pristinity, degradation and replacement: the three dimensions of human impact on island vegetation, by V. Rull, has been accepted for publication in the journal Progress in Physical Geography. The abstract is reproduced below.

Abstract: This paper presents three extreme examples of the potential consequences of human settlement on the vegetation of oceanic and continental islands. The Neotropical Pantepui continental archipelago of sky islands is an example of pristinity, which is due to the almost nonexistent human impact because of the remoteness and inaccessibility of these islands as well as the lack of natural resources to exploit. Easter Island is used to illustrate total vegetation degradation by deforestation and the exhaustion of natural resources, which has transformed the island into badlands with no signs of recovery. The Azores Islands have been chosen to illustrate replacement as, after initial postsettlement deforestation and extractive practices, a further transformative phase consisting of creating an almost totally anthropogenic vegetation with mostly exotic species occurred. The paper describes in some detail the developments of each case and the historical context in which they took place using historical, archeological and paleoecological evidence. Many intermediate states are possible among these three extremes, which can be represented with a ternary diagram (the PDR diagram), which is useful for characterizing the state of each island or archipelago in terms of human impact on terrestrial ecosystems and informing conservation and restoration practices.

The Elsevier book on the paleoecology of Easter Island already published!

Editorial summary. This book synthesizes the available paleoecological knowledge from the last millennia of Easter Island to pave the way towards an integrated interdisciplinary vision of the island’s environmental-ecological-cultural system as a complex functional unit. Human and environmental deterministic views are avoided, and the Easter Island prehistory is analyzed under a holistic perspective of feedbacks and synergies among the different components of the system. The book examines the Easter lsland’s climatic and ecological history, a topic that is not usually addressed in other literature on the island. The book provides a thorough and synthetic account of all paleoecological works developed to date including the latest discoveries. Finally, it attempts to match paleoecological evidence with the results of other disciplines, in the way towards a multidisciplinary framework. The thorough and detailed view of the climatic, environmental and ecological history of the island provided by the book makes it a useful resource for researchers, university professors and graduate students of a varied range of disciplines including ecology, paleoecology, paleoclimatology, biogeography, sedimentology, limnogeology and others who are interested in incorporating paleoecological knowledge in their investigations.

New Springer book on the prehistory of Easter Island

Springer has approved the publication of a new book entitled The Prehistory of Easter Island (Rapa Nui): Towards a Multidisciplinary Integrative Framework, edited by Valentí Rull and Christopher M. Stevenson.

The book is aimed at presenting representative papers from a range of research fields (anthropology, archaeology, ethnobotany, ethnography, history, linguistics, paleoecology, phylogenetics, phylogeography), in order to provide a thorough interdisciplinary assessment of Easter Island’s prehistory. The main idea is to offer as many different approaches and points of view as possible for the reader to have a fairly complete vision of the state of the art in Easter Island research and the possible future developments.

The book will have 40 chapters written by 90 researchers including many of the most recognized experts on Easter Island research. These chapters are organized into six thematic sections:

  • Transpacific voyaging and settlement
  • The ancient Rapanui culture
  • Climatic and environmental change
  • Deforestation and extinctions
  • Collapse or resilience?
  • European contact

A final chapter will provide a multidisciplinary synthesis considering all aspects and approaches discussed in the book. For more information, download the preliminary table of contents. The book is projected to be issued by fall 2021.


Don’t forget the Elsevier book about the paleoecology of Easter Island, to be published in September this year. Reference: Rull, V. 2020. Paleoecological Research on Easter Island: Insights on Settlement, Climatic Changes, Deforestation and Cultural Change. Elsevier, Amsterdam. ISBN 9780128227275.

A lesson for global change?

We live in a society that is incapable of controlling itself in the face of an epidemic disease that directly threatens our own individual lives. How can we expect that the same society becomes worried about the possible consequences of global change for Earth and for future human generations? Our future seems clearer than ever.

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…
