“…A marked and rapid shift in vegetation composition in the low latitudes of South America is the expansion of the Araucaria forest in southern Brazil. This southern region of the Atlantic Rainforest (Mata Atlântica) in eastern Brazil was characterized by species rich campos (grasslands) during the last glacial which changed little in composition until the midHolocene (Behling et al, 2004;Pieruschka et al, 2012). The expansion of the forest is interpreted to result from increased moisture availability (Behling, 2002) and this interpretation is generally consistent with the oxygen isotope record from Botuver a Cave (Wang et al, 2006).…”

“…[2][3][4][5][6] However, the corn is the only crop species of grasses recorded (Figure 1) in the Quaternary samples of the region. [4][5][6][7] Many species of crops belong to Poaceae family. However, the distinction of pollen grains of native and crop species is difficult due to uniform pollen morphology of Poaceae species, except the pollen of corn that has size very large.…”

Anthropic pollen indicators: poaceae pollen of non-native species in Southern Brazil

The Poaceae species have their use for food known in Brazil and in the world. Maize, which today accounts for 21% of human nutrition, was changed 9,000 years ago from Teosinte. Many indigenous people grow maize in South America to feed the tribe. In Brazil, several Poaceae species of African origin were introduced accidentally purposely in the colonial period, to be used as fodder, as was the case of annoni grass (Eragrostis plana Nees). Palynological studies may reconstitute a vegetation of the past, but due to the similarity of Poaceae pollen grains, so far maize (Zea mays L.) can be identified with the safety of the palynological studies. The aim of the study here is to identify and describe the pollen grains of Poaceae exotic cultivated species. The pollen grains were collected from herborized plants and processed by usual techniques of palynology (acetolysis). The results allow identification of three pollen groups (pollen of ornamental, cereal and corn plants). Pollen morphology of 14 species of exotic Poaceae in Rio Grande do Sul state showed differences in sizes of pollen grains. The results of this research showed that cultivars of grasses can be identified in sedimentary profiles. However, some pollen grains have the size of pollen similar to Poaceae pollen of native species. Thus, it is necessary knowledge about the vegetation of study area and surrounds distributed cultivars of grasses. Nevertheless, this pollen database is important to mapping with more precision the cultivation of these cereals in the Late Holocene. Citation: Radaeski JN, Evaldt ACP, Bauermann SG.

“…A Floresta Ombrófila Mista (FOM) Alto-Montana faz parte de um mosaico formado por florestas e áreas de vegetação aberta, constituídas por campos naturais (Estepes), considerados como uma vegetação proveniente de períodos glaciais do Quaternário, mais secos e frios (BEHLING et al, 2007;BEHLING;PILLAR, 2007;SILVA;ANAND, 2011), e por áreas desmatadas para dar origem a atividades antrópicas. De acordo com Jeske-Pieruschka et al (2013), nos locais em que as condições edáficas são favoráveis, o clima atual da região sul favorece a expansão do componente florestal sobre as áreas abertas, sendo este processo limitado pelas ações antropogênicas desde o Holoceno Tardio.…”

O objetivo deste estudo foi conhecer os padrões demográficos da regeneração natural do componente arbustivo-arbóreo e determinar se esses são influenciados pelas variáveis ambientais, em três áreas de campo em regeneração natural, adjacentes a fragmentos florestais de Floresta Ombrófila Mista Alto-Montana, no Planalto Sul Catarinense. Foram instaladas três transecções, uma por área, de 20x100 m, subdividas em sub-parcelas de 10x10 m, perpendiculares à borda dos fragmentos, com sua extensão cobrindo a área de campo. Amostraram-se todos os indivíduos regenerantes arbustivo-arbóreos com 20 cm ou mais de altura. Em cada sub-parcela, foram coletados os seguintes dados ambientais: propriedades físico-químicas dos solos, grau de compactação dos solos e topografia. Um ano após o inventário, foram obtidas as taxas de dinâmica para as três comunidades e para as populações, e os padrões encontrados foram relacionados com as variáveis ambientais. Os dados foram analisados por meio de testes de Kruskal-Wallis, testes de comparações múltiplas, teste de qui-quadrado aplicado a tabela de contingência, teste de correlação, Análise de Componentes Principais (PCA) e modelos lineares mistos. Os resultados demonstraram que no período estudado, o processo de regeneração natural do componente arbustivo-arbóreo encontra-se em fase inicial e foi caracterizado pelo incremento na abundância de indivíduos, estabilidade na riqueza, independência espacial entre a mortalidade e o recrutamento e limitação do recrutamento em função da baixa fertilidade natural do solo e elevada disponibilidade de Al.
