Abstract Indigenous people have been managing fire‐prone landscapes for millennia, especially in tropical savannas, thereby maintaining carbon stocks and pyrodiversity ensuring food security. In some indigenous lands Brazil, fire brigades are composed of people, integrating their traditional knowledge Brazilian management policies; however, the effectiveness is largely undocumented. Nevertheless, we need to know influence on patterns. Here, evaluate an 18‐year historical series patterns burn...
Evaluation of the effects flooding on seedling recruitment from seed banks helps in understanding vegetation regeneration floodplains. We studied simulated richness and abundance of, temporal variation in, soil bank a floodable savanna Pantanal wetland, under two conditions: 1) Post-flood = inundated for 30 days followed by irrigation; 2) Non-flooded only irrigated. recorded emerged seedlings biweekly 120 found total 124 species treatments, most abundant were annual herbs (e.g., Richardia...
Abstract Flood and fire can harm plants but they have survival strategies, such as the seed bank. We aimed to determine influence of flood on richness, abundance diversity Sampling was carried out in October/2013, year prolonged drought, October/2014, a heavy flood, ten areas along Paraguay River. The were selected satellite images, five with old burn (2010, three years before sampling) recent (2013, months sampling). In each area, we marked 20 m long transect × cm quadrats where collected 5...
The soil seed bank is a regeneration strategy for most plant species in wetlands such as the Pantanal. Soil depth an indicator of persistence. Therefore, our objective was to assess composition potentially persistent bank, and verify effect on abundance, diversity functional composition. We collected 40 samples (10 x 10 5 cm) at four depths: 0-5, 5-10, 10-15 15-20 cm, ten areas along Paraguay River (N = 10/depth). placed trays greenhouse, recorded seedlings emergence three months. found 44...
Abstract In tropical wetlands, in addition to flooding, fire also contributes the structure of biodiversity across environmental gradients. fire‐prone ecosystems, flower‐rich refuges can be maintained by a seasonal patch‐burning mosaic. Here, we evaluate how set floral traits that influence and are related pollination systems tree non‐tree species varies response spatial patterns frequency landscape with floodable flood‐free areas. We classified sampled according flower size, color, shape,...
Abstract Aims Our objective was to quantify the contributions of seed bank and established vegetation species composition, functional composition diversity, discuss implications these differences in regeneration persistence floodplain plant communities. Methods We sampled all ground cover up 1.5 m height 25 plots (10 × 1 m) distributed across five sites dry rainy seasons a periodically flooded savanna Pantanal wetland, Brazil. evaluated soil by seedling emergence method. Important Findings...
In this first report on the flora of Mauritia flexuosa L. f. palm swamps in Pantanal wetland Brazil, we surveyed and compared angiosperm eight areas plain to determine if they correspond veredas. Studied were four sites near upland Rio Verde Coxim, Parque Estadual do Negro, Aquidauana, state Mato Grosso Sul, Brazil. To species similarity, our results with inventories aquatic plants veredas state. Using wandering method, recorded a total 385 phanerogams. Species richness was higher...
Climate influences species distribution and selects different morphological traits. The Chaco biome has climatic gradients, leading us to question trait distribution. Using Fabaceae as a study model, we aimed understand how the dispersal traits of this family, such fruit types, syndromes units, are distributed along gradients in Chaco. We performed spatial analysis order generate predictors thus identify on which scales climate soil variables relevant Also, used Threshold indicator rate...
A restauração ecológica é essencial para manter a biodiversidade frente às mudanças globais do clima. O banco de sementes principal fonte manutenção da variabilidade genética populações e comunidades. Uma avaliação precisa das contidas no solo após um evento extremo sazonal em áreas úmidas traz respostas quanto ao potencial regeneração natural. Dessaforma, objetivamos investigar o uso dos bancos como uma ferramenta degradação florestas ripárias sua capacidade eventos fogo inundações. foi...
<title>Abstract</title> Climate change and land use are intensifying wildfires in the Brazilian Pantanal, altering dynamics of natural grasslands. Grasslands subjected to burning can experience turnover species composition depending on fire intensity frequency. Understanding persistence regeneration strategies is essential for predicting when where fire-induced changes plant communities may occur. Our objective was evaluate how affects seedling stage influences survival development,...
RESUMO Este estudo verificou as diferenças na riqueza, densidade e composição de espécies do banco sementes sob a copa es arbóreas área campo adjacentes relação entre altura total caule da com riqueza sementes. Foram coletados o 10 indivíduos cada (Curatella americana L., Luetzelburgia auriculata (Allemão) Duckee, Copernicia prunifera (Mill.) H.E.Moore)), em pontos adjacente. A foram maiores copas das espécies. apresentou positiva e, negativa. As estudadas potencializam formação sementes,...
Forest fragmentation affects the structure and interactions of plant communities on several levels is considered one causes extinction species. This study aimed to verify if size, isolation, altitude soil attributes influence species richness, basal area, abundance composition in Atlantic fragments. We sampled shrubby-arboreal individuals ten fragments, measured isolation. To effects environment abundance, richness we utilized generalized linear mixed models; detect patterns distribution...
