First issue of the new open-access journal Quaternary

The first issue of the newly-created open-access jorunal called ‘Quaternary‘ has just been released. This issue contains eight papers: two editorials, a communication, four research papers and a review. Five of these papers belong to the special issue ‘Advances in Quaternary Studies: the Contribution of the Mammalian Fossil Record‘ and one is part of the special issue entitled ‘Feature Papers in Quaternary‘.

The journal covers all aspects of Quaternary science, embracing the whole range of scientific fields related to geological, geographical, biological, physical, chemical, environmental and human sciences. There are no limits on space, figures and color (see the author’s instructions). More details are available in the journal website, where the inaugural editorial paper can be read and downloaded.

Curso de postgrado sobre las bases científicas del Antropoceno

El Departamento de Postgrado y Especialización del CSIC abre un nuevo curso titulado: El Antropoceno: bases científicas, que tendrá lugar entre el 15 de enero y el 15 de febrero de 2019, en el Instituto de Ciencias de la Tierra Jaume Almera, en Barcelona.

El objetivo de este curso es proporcionar las bases científicas sobre las que se sostiene el concepto de Antropoceno, sin ninguna preconcepción específica, para que los asistentes se formen su propia opinión sobre un tema tan actual y polémico. El Antropoceno, definido como una nueva época geológica caracterizada por la huella humana global sobre el Sistema Tierra, se ha convertido en un término muy usado en una gran variedad de disciplinas. Sin embargo, todavía hay una disparidad de ideas y criterios sobre el origen y la validez científica de este término. En este curso se discuten estos aspectos para una audiencia no especializada. Las posibles consecuencias de la presión humana incontrolada sobre el Sistema Tierra y la necesidad de reconsiderar nuestra relación con el planeta no se cuestiona. El curso está centrado en la utilización de este argumento para proponer que hemos entrado en una nueva época de la Escala del Tiempo Geológico.

El curso está dirigido a graduados universitarios y estudiantes de último curso de una amplia variedad de disciplinas, tanto de ciencias como de humanidades y ciencias sociales.

A holistic view of Easter Island’s history

CLAFS (Cimate-Landscape-Anthropogenic Feedbacks and Synergies) is a hypothesis integrating natural and anthropogenic drivers of ecological and cultural change aimed at unraveling Easter Island’s history under a holistic perspective

Our latest paper paper reviews the existing hypotheses concerning the cultural shift from the Ancient Cult (AC) to the Birdman Cult (BC) that occurred on Easter Island (Rapa Nui) during the last millennium and introduces a holistic new hypothesis called CLAFS (Climate-Landscape-Anthropogenic Feedbacks and Synergies), which considers a variety of potential drivers of cultural change and their interactions. The CLAFS hypothesis can be tested with future paleoecological studies on new sedimentary sequences such as the new continuous and coherent record encompassing the last millennium from Rano Kao (KAO08-03) using a combination of pollen, non-pollen palynomorphs (NPP), charcoal, and fecal lipid analyses, at decadal to multidecadal resolution. The Kao record should be compared with other continuous records of the last millennium available for the two other freshwater bodies of the island, Rano Aroi and Rano Raraku, to obtain an island-wide perspective of spatio-temporal deforestation patterns in relation to climatic shifts and human activities. The CLAFS hypothesis predicts that the shift from the AC to the BC was associated with the drying out and deforestation of Rano Raraku (the center of the AC) by ~1,570 CE, followed by human migration to Rano Kao (the social center of the BC), where freshwater and forests were still available. Under the CLAFS scenario, this migration would have occurred by ~1,600 CE. Findings to the contrary would require modification and refinement, or outright rejection, of the CLAFS hypothesis and the consideration of alternate hypotheses compatible with new paleoecological evidence. Regardless the final results, archeological evidence will be required to link climatic and ecological events with cultural developments.

Quaternary palaeoinsights open for submission

The journal Quaternary launches a new Topical Collection entitled Palaeoinsights, which aim is to provido a forum for essays and opinion papers on topics of interest for the science of Quaternary and for palaeosciences, in general.

This collection is aimed at encouraging open and constructive conceptual discussion on important topics in Quaternary science. The main objectives are to progress towards agreement on controversial issues, to introduce new unconventional approaches to existing problems, to find novel pathways of scientific progress, and to enhance the scope of Quaternary research as the basis for a more integrative view of our discipline within the framework of earth sciences. Historical and philosophical insights on Quaternary science and palaeosciences, in general, are also relevant. Authors may want to think not only about the scientific practice itself but also on why we do it and why we do it in the way we do. This transcends our routine activities and stimulates introspection on ourselves as science practitioners and also on the meaning of our discipline in the general context of knowledge generation. Potential impacts of Quaternary research on society, in the form of practical applications or cultural improvement—including formal education, popularization or policy making—are matters of interest as well. The main topics suggested are listed below but contacting the editor for additional proposals is encouraged.

Suggested topics

  • Opinions on controversial topics
  • Novel perspectives and unconventional approaches to persistent problems
  • Current challenges of Quaternary research
  • Philosophical issues involving the Quaternary
  • Peculiarities of Quaternary science
  • History of Quaternary research
  • The future of Quaternary science
  • Research careers in Quaternary science
  • Teaching the Quaternary
  • Quaternary science and society
  • Popularization of Quaternary science
  • Quaternary science and future environmental change
  • Contribution of Quaternary research to policies and regulations

Very simple yes-and-no questions about the Anthropocene

The Anthropocene – a real mess…

  • Have humans changed the configuration and functioning of the Earth System? Yes.
  • Should we change our relationships with our planet to be sustainable? Yes.
  • Should we stop overexploitation, contamination and garbage accumulation at once? Yes.
  • Should we change the global socio-economic system to improve the situation? Yes.
  • Are we in a new historical phase of humankind? Yes.
  • Are we in a new geological epoch? No.
  • Why not? Is not true that science has already accepted the Anthropocene as a new geological epoch? No.
  • OK, but this is a matter of time, isn’t it? No.
  • Is there a scientitifc proposal to formalize the Anthropocene as a new geological epoch? No.
  • Is it in progress? Yes.
  • Is it likely to be approved in its present state? No.
  • Regardless formal acceptance, could we name the new historical phase the Anthropocene? No.
