Congruent morphological and molecular differentiation, coupled with paleoecological evidence of an ancient vicariance, support the view (Howard et al.
In an analysis of a Lake Valencia core, Leyden (1985) found no evidence supporting the region as a Pleistocene refugium, and concluded that, "Pleistocene refugia in the Neotropics have yet to be documented by paleoecological data.
Paleoecological studies on the impact of the Younger Dryas upon the vegetation can therefore provide important insights into ecological questions such as the nature of vegetation response to extremely rapid and severe climate cooling and warming.
For the Petexbatun region, compared with the central Peten, our initial paleoecological evidence indicates more forest survival through the period of highest population density, the Late Classic of the ninth century A.
Benthic foraminiferal assemblages have been currently used as proxies for determining paleoecological features, which may have controlled their development due to the close relation between them.
1982a, b, 1990; Lee, 1996), and paleoecological studies reveal that these environments return to conditions that existed prior to ash deposition events within 10 to 300 years (Barsdate and Dugdale, 1972; Abella, 1988; Lotter et al.

Assessment of the effects of predation over geological timescales, essential for paleoecological and evolutionary studies, has proved difficult, not least because most traces of predation are rarely preserved; most types of predation destroy the prey or leave no traces on the preservable hard parts of the victim.
