“…They help in the interpretation of the resilience of this ecosystem, which is why they were not excluded from the accounting for species density. The A. poiretii species was the most abundant, especially in the Pimenteira area (Table 1 and Figure 4), but it is more common to find it in more disturbed ruderal areas and in open vegetation (Sousa et al, 2017), which does not characterize this area that is less disturbed and has a more closed canopy. However, the Pimenteira area is between temporary streams, which favored the number of viable seeds in this environment, with higher species richness and diversity (Lima et al, 2013).…”

Nucleation is a technique widely used in restoration projects, but the transposition of the seed bank in the soil with greater depth is still incipient, especially in the Caatinga Biome. Thus, it evaluated whether the two seed bank transposition techniques (litter and topsoil) collected in two natural environments of the Mata da Pimenteira State Park (PEMP) provide seedling emergence in degraded areas of the Caatinga. Litter and topsoil techniques were transported from two Natural Environment Zone (ZAN) of the park, Serra Branca and Pimenteira, to two restoration areas in UFRPE/UAST in plots distributed in nuclei. The design was in randomized blocks, for litter in 2016 and topsoil in 2017. The highest average of emerging seedlings occurred in the surface forest soil transposition (topsoil) technique, mainly in the collection environment of the pepper tree area of the Pimenteira State Park. Herbaceous (herbs) were more evident in the topsoil (63.25%) than in litter (61%) and the species Alcalypha poiretii Spreng. was the most abundant in the Pimenteira area while the species Croton hirtus L’Hér. in the Serra Branca. The topsoil technique showed higher species richness, while litter was less uniform. However, both techniques presented a potential for species conservation, and the Pimenteira environment provided higher viable seed bank potential in degraded areas under Caatinga ecosystem conditions.

Nosso objetivo foi estudar os impactos causados pela espécie exótica invasora Boerhavia diffusa sobre o estrato herbáceo e arbustivo em uma área ripária de Caatinga em Canindé de São Francisco, SE. Para isso, utilizamos o método de parcelas e amostramos dois ambientes nos quais todas as espécies herbáceas foram contabilizadas e estimados os parâmetros estruturais das comunidades. Amostramos 13 espécies e 513 indivíduos no ambiente invadido e 36 espécies e 1.056 indivíduos no ambiente não invadido. A diversidade de espécies baseada no índice de Shannon-Wiener (H’) foi de 1,69 para o ambiente invadido e de 2,63 para o ambiente não invadido. Nossos resultados sugerem que Boerhavia diffusa afeta de maneira negativa a diversidade de espécies do estrato herbáceo e arbustivo autóctone da área estudada.

A critical taxonomic and nomenclatural review of the Brazilian species of Acalypha (Euphorbiaceae, Acalyphoideae) is presented. As a result, 40 species (44 taxa including six subspecies) are accepted, 37 of them native (17 endemic) and three introduced; also, 132 names are considered synonyms, 28 of them for the first time. Two new combinations are proposed: Acalypha brasiliensis subsp. asterotricha and A. brasiliensis subsp. psilophylla, previously considered varieties of A. brasiliensis. Information about types is provided for all the valid names, and 54 lectotypes and one neotype are designated. Identification keys and detailed distribution maps of all the native taxa are also provided.
