Influência de diferentes tipos de estacas e substratos na propagação vegetativa de Hyptis pectinata

Hyptis pectinata, belonging to Lamiaceae family, is used in northeastern folk medicine due to its phytotherapeutic properties for treatment of inflammation, bacterial infections, and pain. The objective of this work was to evaluate the influence of the cutting position of the branch and the composition of the substrates in the aerial and root development of H. pectinata plants. Cuttings were selected from the apical, median, and basal plants grown in the seed house of Garanhuns municipality, PE. Cuttings were propagated in different substrates (soil, manure, and soil + manure). Results showed that highest budding number occurred for basal cutting (4.45 un.) in the soil + manure substrate. The highest average number of roots occurred in cutting from the median and basal positions in the soil + manure substrate. The best substrate for the rooting of cuttings of H. pectinata is the soil associated with manure, and the cuttings from the median and basal positions are the most suitable for the vegetative propagation of this species.Hyptis pectinata, pertencente à família Lamiaceae, é utilizada na medicina popular nordestina por apresentar propriedades fitoterápicas para o tratamento de inflamações, infecção bacteriana e dor. O objetivo deste trabalho foi avaliar a influência da posição da estaca no ramo e composições de substratos no desenvolvimento aéreo e radicular de plantas de H. pectinata. As estacas foram selecionadas da parte apical, mediana e basal de plantas mantidas na sementeira municipal de Garanhuns, PE. As estacas foram propagadas em diferentes substratos (terra, esterco, e terra + esterco). Os resultados evidenciam que o maior número de brotações ocorreu para estaca basal (4,45 un.) no substrato (terra + esterco). O maior número médio de raízes ocorreu em estacas das posições mediana e basal sob o substrato (terra + esterco). O melhor substrato para enraizamento das estacas de H. pectinata é a terra associada com o esterco, e que as estacas da posição mediana e basal são as mais indicadas para a propagação vegetativa desta espécie

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
