Resumo: | In regions with a hot and semi-arid climate, such as Brazilian dry forests, vegetation exhibits morphological, anatomical and physiological strategies to promote efficiency in the use of available resources or their limitation. These environments act as environmental filters in selection of functional traits with ecological strategies that guarantee the survival of the vegetation. Among the functional traits, wood density and foliar phenology can be used to know the process of establishment and survival of vegetation in the most varied environments, also being used as stresses indicator, mainly water. In this context, the objective of this study was to evaluate the influence of climatic variables on the distribution of wood density and foliar phenology in Seasonally Dry Tropical Forests communities in Brazil based on a database compiled from 114 communities. For studied communities selection, floristic lists were searched in online databases. For data on the trait values, we also used a database of global wood density and literature on species foliar phenology. Climatic variables data were obtained from remote sensing based on raster available online. It was observed that high average values of wood density and the highest percentage of deciduous species were the dominant ecological strategies in dry forest communities. It has also been found that these strategies are related to places where rainfall rates are lower and still present high environmental stress. These results allow the understanding that seasonally dry tropical forests are ecosystems in which due to the environmental stress they are in, they select more conservative strategies to use the little available resource, with a strategy of resistance and/or tolerance to dry environment and arid region, with a higher dominance of deciduous species and higher wood density the greater stress. The results also allow us to predict how other ecosystems can behave (functionally) as a result of climatic changes that have been taking place. |

Esses ambientes agem como filtros ambientais na seleção de traços funcionais com estratégias ecológicas que garantam a sobrevivência da vegetação. Dentre os traços funcionais, a densidade de madeira e a fenologia foliar podem ser utilizadas para se conhecer o processo de estabelecimento e sobrevivência da vegetação nos mais variados ambientes, também sendo utilizadas como indicadores de estresses, principalmente hídrico. Nesse contexto, o objetivo desse estudo foi avaliar a influência de variáveis climáticas, na distribuição da densidade de madeira e da fenologia foliar em comunidades de Florestas Tropicais Sazonalmente Secas no Brasil com base num banco de dados compilados a partir de 114 comunidades. Para a seleção das comunidades estudadas, foram realizadas buscas de listas florística em bancos de dados online. Para a informação do valor dos traços, também foram utilizados banco de dados de densidade de madeira global e na literatura sobre a fenologia foliar das espécies. Os dados de variáveis climáticas foram obtidos a partir de sensoriamento remoto, baseados em raster disponíveis online. Observou-se que elevados valores médios de densidade de madeira e a maior porcentagem de espécies decíduas foram as estratégias ecológicas dominantes nas comunidades de florestas secas. Também foi encontrado que essas estratégias estão relacionadas a locais em que as taxas pluviométricas são mais baixas e que ainda apresentam elevado estresse ambiental. Esses resultados possibilitam o entendimento de que as Florestas Tropicais Sazonalmente Secas são ecossistemas em que, devido ao estresse ambiental ao qual se encontram, selecionam estratégias mais conservativas ao uso do pouco recurso disponível, com uma estratégia de resistência e/ou tolerância ao ambiente seco e árido, apresentando maior dominância de espécies decíduas e com maior densidade de madeira quanto maior for esse estresse. Os resultados também nos possibilitam prevermos como outros ecossistemas poderão se comportar (funcionalmente) em decorrência das mudanças climáticas que vêm ocorrendo.Submitted by Jean Medeiros (jeanletras@uepb.edu.br) on 2021-11-19T13:02:37Z No. of bitstreams: 1 PDF - D’Ávilla Ruama Fernandes Lopes Gomes.pdf: 2260930 bytes, checksum: d5390115df2950313d4fff3585f17749 (MD5)Approved for entry into archive by Rosalvo Andrade (rosalvo_andrade@servidor.uepb.edu.br) on 2021-11-20T00:07:08Z (GMT) No. of bitstreams: 1 PDF - D’Ávilla Ruama Fernandes Lopes Gomes.pdf: 2260930 bytes, checksum: d5390115df2950313d4fff3585f17749 (MD5)Made available in DSpace on 2022-01-05T11:56:16Z (GMT).

In regions with a hot and semi-arid climate, such as Brazilian dry forests, vegetation exhibits morphological, anatomical and physiological strategies to promote efficiency in the use of available resources or their limitation. These environments act as environmental filters in selection of functional traits with ecological strategies that guarantee the survival of the vegetation. Among the functional traits, wood density and foliar phenology can be used to know the process of establishment and survival of vegetation in the most varied environments, also being used as stresses indicator, mainly water. In this context, the objective of this study was to evaluate the influence of climatic variables on the distribution of wood density and foliar phenology in Seasonally Dry Tropical Forests communities in Brazil based on a database compiled from 114 communities. For studied communities selection, floristic lists were searched in online databases. For data on the trait values, we also used a database of global wood density and literature on species foliar phenology. Climatic variables data were obtained from remote sensing based on raster available online. It was observed that high average values of wood density and the highest percentage of deciduous species were the dominant ecological strategies in dry forest communities. It has also been found that these strategies are related to places where rainfall rates are lower and still present high environmental stress. These results allow the understanding that seasonally dry tropical forests are ecosystems in which due to the environmental stress they are in, they select more conservative strategies to use the little available resource, with a strategy of resistance and/or tolerance to dry environment and arid region, with a higher dominance of deciduous species and higher wood density the greater stress. The results also allow us to predict how other ecosystems can behave (functionally) as a result of climatic changes that have been taking place. |
