“…A categoria ecológica refere-se ao conjunto de espécies indicadas pela literatura como fornecedoras de sementes e plântulas usadas em programas de reflorestamento ou recuperação de áreas degradadas, agrossilvicultura, cortina vegetal ou recurso para a fauna (FAO, 1992;Elias & Santos, 2016). Do total de espécies (46) relacionadas à categoria, 56% são reconhecidas como de estágios sucessionais avançados e de prioritária relevância para recuperação de áreas degradadas em regiões de FOM (Fockink, Zangalli, de Oliveira & Kanieski, 2020), enquanto 8% são identificadas como espécies pioneiras, características de estágios iniciais de sucessão ecológica (Trentin, Estevan, Rossetto, Gorenstein, Brizola & Bechara, 2018;Fockink et al, 2020). As espécies Ilex paraguariensis St.-Hil.…”

O objetivo do estudo foi caracterizar a potencialidade de usos não-madeireiros de espécies florestais presentes em remanescentes de três parques naturais municipais, em Bituruna, Paraná. Para a coleta de dados foram instaladas parcelas em cada um dos parques. Cada parcela foi definida por uma linha amostral de 25 metros, com largura de 2 metros para cada lado da linha, totalizando 4 metros de largura. O levantamento florístico foi realizado através do método guiamento, obtendo-se amostras de espécies arbóreas e arbustivas com altura igual ou superior a 50 cm, medindo-se a partir da base do solo. Material botânico foi coletado e as amostras foram etiquetadas para identificação em herbário. Posteriormente, as espécies identificadas foram classificadas em categorias de usos, de acordo com a bibliografia consultada. As categorias definidas foram: alimentícias, artesanal, ecológica, fibra, medicinal, produtos bioquímicos, óleos essenciais, ornamental e outros usos. O estudo identificou a ocorrência de 141 espécies pertencentes a 39 famílias botânicas, sendo que 102 espécies foram identificadas relacionadas com as categorias de usos apontadas pelo estudo. As famílias que apresentaram maior número de espécies para usos não-madeireiros foram: Myrtaceae (17), Asteraceae (11) e Lauraceae (7). As categorias com maior número de espécies foram: medicinal (54), ecológica (46), ornamental (43), óleos essenciais (24), alimentícia (21) e produtos bioquímicos (17). As demais categorias apresentaram valores inferiores a 10 espécies. Nos locais de estudo ocorre um número significativo de espécies com potencialidade de uso não-madeireiro, muitas não são devidamente pesquisadas e comercializadas.

Demography and spatial distribution of a threatened species from the Atlantic Forest in southern Brazil: differences between urban and rural remnants

et al. 2023

Logging and agricultural exploitation have led to the degradation of Araucaria Forest remnants and the alteration of its last preserved patches. This forest typology contains many endangered plant species, as is the case of the tree Oreopanax fulvus Marchal. To support conservation of this species and understand how different landscape matrices can influence its populations, we evaluated the demographic structure and spatial distribution of O. fulvus in two Araucaria Forest remnants in Paraná state. We delimited two plots (urban and rural population), each with 1 ha, subdivided them into 100 subplots (10 x 10 m), and recorded diameter at ground level (DGL), height, and coordinates of two post-germinative developmental stage of individuals. In each subplot, we measured slope, luminosity, and canopy height. We used Ripley’s K function analysis to describe distribution patterns of the species and the spatial relationship between mature and juvenile trees. We performed correlations between abundance and environmental and structural variables of the O. fulvus populations. Abundance varied between remnants, from 183 individuals/ha (12 mature and 171 juvenile) to 1306 individuals/ha (10 and 1296). The remnants varied in abundance and plant frequency. The species showed an investment in seedling banks. Most juvenile had DGL up to 3.0 cm and height up to 1.0 m and presented aggregated spatial distribution, while adults had random distribution. In the rural population juvenile abundance were correlated with canopy height (positively) and distance to mature trees (negatively). The slope was correlated for both sites, but oppositely, indicating that other factors might have interfered in the regeneration abundance. The urban remnant showed a high abundance of this endangered species, calling attention for potential studies in urban arborization, management and conservation of these remnants.

Phenological patterns of Oreopanax fulvus (Araliaceae) in remnants of Araucaria Rainforest in Paraná, Brazil

et al. 2021

Oreopanax fulvus is a species endemic to the Brazilian Atlantic Forest, assessed as rare and vulnerable in the states of Paraná and Rio Grande do Sul, respectively. This adverse situation requires conservation actions that must be supported by the understanding of its autecology. We aimed to identify the phenological patterns of O. fulvus populations from two Araucaria Rainforest remnants in Paraná. Monthly phenology monitoring of 19 trees in each site was performed over 24 months. We quantified the vegetative (i.e., leaf flushing, mature leaves, and leaf-senescence) and reproductive phenophases (i.e., buds production, blooming, immature, and mature fruits). Circular statistics based on activity index were applied to identify the phenophases seasonality. Spearman correlations were performed among phenophases and meteorological parameters. Leaf flushing and mature leaves were recorded in all months, with a decrease of mature leaves during November and December. Leaf-senescence was seasonal, occurring from May to December. The reproductive phenophases were seasonal: blooming from January to May; and fruiting from March to November, with fruits starting to mature in September. Vegetative and reproductive phenophases were highly influenced by average temperature and photoperiod. Although there were dissimilarities in reproductive phenological patterns, the different populations studied had similar phenological performances.
