Ecology of the past

Ansis Blaus is a Latvian postdoctoral research associate exploring patterns of climatic and anthropogenic change in the Neotropical Paleoecology Research Group led by Mark Bush at Florida Institute of Technology. He earned his Ph.D. in Earth Sciences from Tallinn University of Technology, Estonia. Supervised by Dr. Triin Reitalu he worked on modern pollen-plant relationships and palaeoecological reconstructions of peatlands and calcareous spring fens with an emphasis on biodiversity and plant functional trait reconstructions.

Currently, at Florida Tech, Ansis works on pollen data and other proxies from the sediment cores collected in the tropical Amazon. He investigates the tropical forest changes in relation to the global climate from a historical perspective, particularly during the Last Glacial Period and the Last Interglacial ca. 130 thousand years ago. His work will shed light on the history of dynamics and climate tipping points in the Amazonian rainforest. This research is particularly important in the face of the current global climate crisis and could help to anticipate the tropical forest response to the changing climate in the future.

Another objective of Ansis’s work is to study the pollen signature of human disturbance in the Amazon Basin as a means to model and interpret human presence and activities in the past and to understand human-nature interactions in tropical forest ecosystems in different spatial and temporal scales. For that, he is collaborating with the University of Amsterdam, Institute for Biodiversity and Ecosystem Dynamics, and working on a project aiming to quantify tropical pollen assemblages led by Crystal McMichael.

Ansis is fascinated by the potential revelations that come with the intersection of neoecology and paleoecology and human interactions. His interest in paleoecology, biodiversity, and various natural processes comes through the sense of pursuing a higher purpose for society and the well-being of our planet, and from the concern that humans have altered tropical forests and most other ecosystems in the world to the level of a negative rebound effect. Ansis believes that we must study and understand these ecosystems from different perspectives to decrease the current damage, predict future scenarios and to develop conservation strategies for both nature and human well-being.
