A methodological proposal for the recovery of palynomorphs from snow and ice samples

“…1 Museu Nacional, Universidade Federal do Rio de Janeiro, 20940-040, São Cristóvão, RJ, Brazil 2 Universidade Veiga de Almeida, 20271-020, Rio de Janeiro, RJ, Brazil as those performed by Linskens et al (1993), Harmata & Olech (1991), Vergamini et al (2006) and Parnikoza et al (2011) have documented the atmospheric transport of pollen grains; however, they did not analyze matrices of water, snow or ice.…”

“…The morphology and morphometry of such structures have been widely used as auxiliary tools of botanical taxonomy. They also have applications in the field of ecology, including aerobiological (Anderson et al 1998), allergenic (Vergamini et al 2006) and paleoenvironmental studies (Donizeti 2004;Héguy et al 2008). Pioneering palynological analyses of snow and water from melting lakes showed positive results for pollen grains and spores of plants with geographic distributions in South America (Agostini et al 2017).…”
