The burgeoning field of phylogenetic paleoecology (Lamsdell et al. 2017) represents a synthesis the related but differently focused fields macroecology (Brown 1995) and macroevolution (Stanley 1975). Through combination data methods both disciplines, leverages theory quantitative to explain temporal spatial variation in species diversity, distribution, disparity. Phylogenetic is ideally situate...
O the past few decades, Quaternary paleoecological studies have provided an impressive global database of pollen and macrofossils. Not only are these fossil records essential for detecting past species distributions (Baker 1959), but they have also played a key role in testing ecological theories and evaluating model predictions of climatic and biotic changes, from the past and into the future....

The paleoecology of tropical Podocarpaceae is reviewed for Africa and Southeast Asia. The family first appeared in the Triassic of Gondwana, after which it diversified through the Cretaceous and earliest Tertiary, and although some Northern Hemisphere Jurassic records are known, it has essentially remained a southern or southernderived family until the present day. It seems to show a preference...
This research focusses on the facies distribution, paleoenvironment and paleoecology of the foraminifera of the Guri Member in the northern Bandar Abbas Hinterland located in the Roydar area of southern Iran. The Guri Member is 570 meters thick and composed of limestone, argillaceous limestone and marl. The distribution of the foraminifera in the study area indicates the existence of three bioz...
The emergence of human behavior, understood as a distinct adaptive pattern among primates, which created a material record in the form of archaeological sites, has been widely studied during the Oldowan phase of human evolution. Behavior, as a crucial part of adaptation, is tightly linked to ecology. The Olduvai Paleoecology and Paleoanthropology Project (TOPPP) stressed the importance of study...
