Montezuma Well

Got to visit an extremely unique place known as Montezuma Well on my ride yesterday. I learned that only five species of animals exist in the Weel’s water due to high levels of dissolved carbon dioxide. A harbinger of future times? pic.twitter.com/qNTDOYR8d4

Historical perspectives on marine ecosystems, fisheries, and futures - Belgium 2020

Rationale: Life in the oceans is changing more rapidly in the current century than ever before. As these changes occur it is more imperative than ever to understand what came before to better frame management of those systems. Oceans Past brings together scholars and practitioners interested in documenting and understanding changes in marine systems and human maritime interactions in past centuries and millennia. The 8th Oceans Past Conference, Historical Perspectives on Marine Ecosystems, Fisheries, and Futures, will enable continued scholarly communication and international exchange towards a fuller understanding of the past, the present status, and potential trajectories of our living marine resources.

Invitation: The conference welcomes researchers, practitioners, policy-makers and students of all disciplines under the unifying view of our oceans as networks of social-ecological or coupled human-nature systems. Presentations are encouraged that explore large-scale and long-term case studies highlighting dynamic changes and interactions in past marine ecosystems, the impacts and legacy effects of human activities on them, the sustainability of iterative or co-evolutionary relationships and, where possible, likely future directions and management implications. If you have an interest in the history of human interactions with life in the ocean and implications for policy and management, sign up now to attend OP VIII in 2020!

Deadline for paper submission: 15 JANUARY 2020

Early Bird registration deadline: 15 FEBRUARY 2020

Working on fossilized oysters in Northern Peru (Tumbes)

Fossilized oysters (organisms living on the earth more than 500 million years) can be used not only to explore the diversity and evolution of this biological lineage in the past but also to use them as indicators of past climatic changes. Here you can see a sample of the hardworking of my colleague and friend, the scientist Ernesto Fernandez (Peruvian Institute of Marine Research -IMARPE) revealing those species that have been sedimented in northern Peru (Tumbes, ~3°30' S). Results coming soon!

Past organisms living on sediments

The presence of diverse Eocene dinoflagellate assemblages in addition to intertidal sediments suggests that portions of the coal-bearing Latrobe Group were deposited in marginal-marine/tidal settings! #FossilFriday #Palynology #NewResearch pic.twitter.com/itWS5WeaD2
