Jesús Rodríguez
Project Leader
Jesús Rodríguez is the curator of palaeontological collections and leader of the Palaeocology Group at the National Center of Research on Human Evolution (CENIEH) at Burgos (Spain). He is a specialist in mammalian palaeoecology although he also participated in several studies on the macroecology of recent mammals. He finished his dissertation on the ecological structure of the Pleistocene mammalian communities from the Atapuerca sites in 1998. During his post- doc period he continued his research on the palaeoecology of Pleistocene mammalian communities and expanded his interest towards the macroecological analyses of recent mammalian communities in collaboration with specialists on the biogeography of recent organism. This collaboration also led to the application of niche modeling approaches to study the extinction of some large mammal species using palaeontological data. Currently, his main research interest focuses on the trophic dynamics of Pleistocene European mammalian communities and intraguild competition as factors conditioning hominin survival opportunities.
Ana Mateos
Project Leader
Ana Mateos is research leader of the Palaeophysiology and Human Ecology Group at CENIEH (Burgos, Spain). She is an archaeologist with a wide expertise on human ecology, faunal remains and archaeozoology. After her PhD in Prehistory at University of Salamanca in 2005, she finished her Master Degree in Primatology at University of Barcelona in 2010. Her current research focuses on studying the biology and ecology of humans and other primates in the framework of Evolutionary Developmental Palaeoanthropology and Behavioural Ecology. During the last years, she focuses on features of human palaeophysiology essential for human survival during the Pleistocene, specially through an experimental bioenergetic approach. She has developed new approaches to study key life history events in hominins like growth and development, or reproduction and their metabolic costs. In the last years, her active promotion of modeling in archaeological and palaeontological studies led to frequent collaborations on human throphic ecodynamics with the CENIEH Palaeoecology Group leaded by Dr. J. Rodríguez.
Maria Rita Palombo
Project Leader
Maria Rita Palombo if Professor in Palaeontology and Palaeoecology and director of the Museum of Palaeontology at Sapienza University of Rome (Italy). Her research mainly focuses on biochronology, palaeobiogeography, palaeoecology and evolution of Cenozoic mammals (mainly from Eurasia), as well as origin and evolutionary patterns of insular mammals, combining empirical and theoretical approaches across a broad range of scales. Recent scientific activity dealing with palaeoecological studies has the twofold aim of investigating the actual impact of climate changes on ecosystems dynamics and evolution, and scrutinizing whether changes over time in the structure of mammalian palaeocommunities were more greatly influenced by biotic interactions or by disturbances to the physical environment faunal. Particular attention is paid to factors promoting mammal dispersals (including hominins) across and between continents and functional diversity trends shown by mammalian palaeocommunity during the Quaternary evolution. Areas of interest include the application of the evolutionary theory to studies of endemic fossil mammals and the generality of ecomorphological rules.
Christine Hertler
Project Leader

He also applies machine learning techniques to produce paleo maps and derive potential hominin habitats and hominin distribution in Europe.
Yul Altolaguirre
Yul Altolaguirre is a PhD student at Goethe University. He works with the ROCEEH team at Senckenberg Research Institute (Frankfurt am Main, Germany). He is specialized in Palynology, the study of pollen and other palynomorphs. In his current project, he is studing palynological samples from South-Easter Spain to carry out a high-resolution reconstruction of climate and vegetation successions during the Early Pleistocene. His analysis of climate and vegetation changes will provide direct evidence for the environment before, during and after the first expansion of early Homo into the Iberian Peninsula. The quantitative reconstruction of climate, regional vegetation units, and local plant communities as parameters of early human environments will support the understanding of how severe and how fast were the Early Pleistocene environmental changes.
