Resumo: | The cactus family has more than 1.500 species in the world, endemic species occurring throughout the national territory. In natural populations, Cactaceae suffer strong anthropic pressures, which considerably increases their risk of extinction. The objective of the work was to carry out a study on the spatial distribution and population structure of Pilosocereus pachycladus F. Ritter subsp. pernambucoensis (F. Ritter) Zappi and Cereus jamacaru DC. subsp. jamacaru in two Caatinga areas of Agreste in the Paraíba, state, Brazil. The study environments are located at the Instituto Nacional do Semiárido (INSA), Campina Grande,PB state and Sítio Umburana, Bananeiras,PB state. It had been plotted 10 parcels wich 400 m² to each study environment, and all individuals of P. pachycladus subsp. pernambucoensis and C. jamacaru subsp. jamacaru were accounted for. The spatial distribution of species did not show a tendency to group in populations located at INSA. In the populations of Sítio Umburana, the tendency is towards grouping. According to the Payandeh cluster index (Pi), the population and absolute density in the populations of Sítio Umburana is higher when compared to INSA populations. For spatial patterns, in the cactus populations of Sítio Umburana, individuals of both species have a grouped distribution and in INSA populations they have a tendency to not cluster. Factors such as natural or man-made disturbances, environmental conditions and availability of resources, influenced the population structure of P. pachycladus and C. jamacaru. |

En poblaciones naturales, las Cactaceae sufren fuertes presiones antrópicas, lo que aumenta considerablemente su riesgo de extinción. El objetivo del trabajo fue realizar un estudio sobre la distribución espacial y estructura poblacional de Pilosocereus pachycladus F. Ritter subsp. pernambucoensis (F. Ritter) Zappi y Cereus jamacaru DC. subsp. jamacaru en dos áreas de Caatinga de Agreste en el estado de Paraíba, Brasil. Los ambientes de estudio están ubicados en el Instituto Nacional do Semiárido (INSA), Campina Grande y en el Sítio Umburana, Bananeiras. Se asignaron 10 parcelas de muestra de 400m² en cada ambiente de estudio, y todos los individuos de P. pachycladus subsp. pernambucoensis y C. jamacaru subsp. jamacaru fueron contabilizados. La distribución espacial de las especies no mostró tendencia a agruparse en poblaciones ubicadas en el INSA. En las poblaciones de Sítio Umburana, la tendencia es al agrupamiento. Según el índice de conglomerados de Payandeh (Pi), la población y la densidad absoluta en las poblaciones del Sítio Umburana es mayor, en comparación con las poblaciones del INSA. Para patrones espaciales, en las poblaciones cactáceas de Sítio Umburana, los individuos de ambas especies tienen una distribución agrupada y en las poblaciones del INSA tienen tendencia a no agruparse. Factores como las perturbaciones naturales o provocadas por el hombre, las condiciones ambientales y la disponibilidad de recursos, influyeron en la estructura poblacional de P. pachycladus y C. jamacaru.A família Cactaceae apresenta mais de 1.500 espécies no mundo, ocorrendo espécies endêmicas em todo o território nacional.

A distribuição espacial das espécies, não apresentaram tendência ao agrupamento nas populações localizadas no INSA. Nas populações do Sítio Umburana, a tendência é ao agrupamento. De acordo com índice de agrupamento de Payandeh (Pi) a densidade populacional e absoluta nas populações do Sítio Umburana é maior, se comparado às populações do INSA. Para os padrões espaciais, nas populações de Cactaceae do Sítio Umburana, os indivíduos de ambas as espécies apresentam distribuição agrupada e nas populações do INSA apresentaram a tendência ao não agrupamento.

It had been plotted 10 parcels wich 400 m² to each study environment, and all individuals of P. pachycladus subsp. pernambucoensis and C. jamacaru subsp. jamacaru were accounted for. The spatial distribution of species did not show a tendency to group in populations located at INSA. In the populations of Sítio Umburana, the tendency is towards grouping. According to the Payandeh cluster index (Pi), the population and absolute density in the populations of Sítio Umburana is higher when compared to INSA populations. For spatial patterns, in the cactus populations of Sítio Umburana, individuals of both species have a grouped distribution and in INSA populations they have a tendency to not cluster. Factors such as natural or man-made disturbances, environmental conditions and availability of resources, influenced the population structure of P. pachycladus and C. jamacaru. |
