“…The phytolith assemblage might indicate the presence of palaeocommunities with a physiognomy of humid psammophile steppe according to the Pt index. This agrees with conclusions of Patterer et al (2019) who state that the El Palmar unit shows a physiognomy of steppe with grasses and shrubs, with a scattered cover of small trees and some palms. Zucol et al (2005) describe a profile in El Palmar National Park with two clearly distinguishable phytolith assemblages.…”

“…The Palm tree Index (Pt) was applied. Patterer et al (2019) defined this phytolith index (Pt) as the ratio of the spheroid echinate phytolith morphotypes in relation to the sum of the grass phytoliths (Poaceae diagnostic short cells).…”

“…Here, we assessed whether the geographical distribution of B. yatay changed over time and whether its past distribution is consistent with the Pleistocene refugia proposed for the South America flora (Whitmore & Prance, 1987) or fossil records of this species dated to the Upper Pleistocene (Patterer & Zucol, 2014;Patterer et al, 2017Patterer et al, , 2019. Additionally, we explored which variables determine the present distribution of B. yatay, using two approaches: bioclimatic-only and bioclimatic with nonclimatic variables.…”

“…It grows in palm groves and displays complex spatial patterns (Batista et al., 2014 ; Marcato, 2004 ). Fossil records, based on phytoliths, link these palm communities to Upper Pleistocene formations of the Uruguay and Paraná Rivers (Patterer & Zucol, 2014 ; Patterer et al., 2017 , 2019 ). The phytoliths of these formations are derived from a humid savanna ecosystem with meso‐megathermic grasslands and open forests (Contreras et al., 2019 ; Erra et al., 2013 ; Patterer et al., 2019 ).…”
