“…Outro aspecto a ser observado sobre o ligustro é o potencial da espécie em se tornar invasora de ambientes naturais, condição verificada por pesquisas em diferentes formações vegetais do sul do Brasil, por exemplo, na Floresta Ombrófila Mista (FOM) (RODRIGUES et al, 2015;NUNES et al, 2018;NOGUEIRA et al, 2020), transição entre FOM e Floresta Estacional Semidecidual (JUNG et al, 2018), Floresta Estacional (HUMMEL et al, 2014ZERWES et al, 2020), entre outras tipologias. A invasão da espécie ligustro também foi observada em países vizinhos como Uruguai e Argentina (FERNANDEZ et al, 2020).…”

“…Conforme Nogueira et al (2020), as diferenças fenológicas do ligustro e das espécies nativas da Floresta com Araucária podem reduzir a competição e facilitar a dispersão eficiente. Outros fatores relacionados com perturbações naturais ou antrópicas, que causam redução de espécies e indivíduos arbóreos, podem catalisar a invasão do ligustro (NUNES et al, 2018). Considerando a plasticidade ambiental já relatada para o ligustro, essas informações referentes a Floresta com Araucária, poderão ser aplicadas com ressalvas a ambientes de outras regiões fitoecológicas com clima semelhante.…”

O presente estudo constitui uma revisão bibliográfica sobre os aspectos fenológicos de duas espécies arbóreas exóticas amplamente utilizadas em ambientes urbanos. Jacaranda mimosifolia D. Don. (jacarandá-mimoso) é uma espécie caducifólia que tende a perder as folhas no inverno, com brotação entre outubro e novembro. A floração, atrativo ornamental da espécie, ocorre entre setembro e março, enquanto a frutificação pode ser visualizada durante a maior parte do ano. Em contraste, Ligustrum lucidum W.T.Aiton (ligustro) é considerada perene (sempre-verde). Nesta, o surgimento de botões florais e a antese podem ocorrer em todos os meses do ano ou períodos menores. A antese tem maior intensidade entre novembro e janeiro, época do ano em que a abundância do pólen potencialmente alergênico pode afetar a saúde da população. Tem frutificação abundante e mais intensa de maio a agosto, comportamento fenológico que facilita a dispersão zoocórica e contribui para o potencial de invasão do ligustro em ambientes naturais. Esta espécie é condicionada por variáveis como fotoperíodo, temperatura e precipitação em pelo menos uma fenofase. Novas pesquisas sobre o comportamento fenológico das espécies jacarandá-mimoso e ligustro são importantes para elucidar a progressão das fenofases e as possíveis relações com variáveis ambientais e condições de cultivo na arborização urbana. Palavras-chave: dendrologia; silvicultura urbana; paisagismo; fenofases; variáveis ambientais. Phenological performance of Jacaranda mimosifolia D. Don (jacaranda) and Ligustrum lucidum W.T.Aiton (privet) species in urban trees ABSTRACT: This study constitutes of a review on phenological aspects of two exotic species widely used in urban environments. Jacaranda mimosifolia D. Don. (jacaranda) is a deciduous species that tends to lose its leaves in winter, with sprouting between October and November. Flowering, the best ornamental attraction of this species, occurs between September and March, while fruiting can be seen along the year. In contrast, Ligustrum lucidum W.T.Aiton (privet) is a perennial species. The flower bud’s emergence and anthesis of this species occur whether along the year or during shorter periods. Anthesis is higher between November and January, which is the time of the year when population’s health can be affected by the potentially allergenic pollen. Privet has abundant fruiting from May to August, which is a phenological behavior that facilitates zoochoric dispersion, and may contributes to the invasion’s potential, typical for this species in natural environments. Privet can be conditioned by variables such as photoperiod, temperature and precipitation, in at least, one of its phenological phases. New researches on the phenological behavior of jacaranda and privet species are important to clarify the progression on phenological phases, to investigate the possible interactions with environmental variables and growing conditions in urban trees. Keywords: dendrology; urban forestry; landscape; phenophases; environmental variables.

Wood density ( ρ ) is a trait involved in forest biomass estimates, forest ecology, prediction of stand stability, wood science, and engineering. Regardless of its importance, data on ρ are scarce for a substantial number of species of the vast Atlantic Forest phytogeographic domain. Given that, the present paper describes a dataset composed of three data tables: (i) determinations of ρ (kg m−3) for 153 species growing in three forest types within the subtropical Atlantic Forest, based on wood samples collected throughout the state of Santa Catarina, southern Brazil; (ii) a list of 719 tree/shrub species observed by a state-level forest inventory and a ρ value assigned to each one of them based on local determinations and on a global database; (iii) the means and standard deviations of ρ for 477 permanent sample plots located in the subtropical Atlantic Forest, covering ∼95,000 km2. The mean ρ over the 153 sampled species is 538.6 kg m−3 (standard deviation = 120.5 kg m−3), and the mean ρ per sample plot, considering the three forest types, is 525.0 kg m−3 (standard error = 1.8 kg m−3). The described dataset has potential to underpin studies on forest biomass, forest ecology, alternative uses of timber resources, as well as to enlarge the coverage of global datasets.

“…Despite the evident importance of exotic species lists, only Paraná, Santa Catarina, Rio Grande do Sul and São Paulo published official lists (MMA 2020). However, it is worth noting the growth in research related to the theme in recent years (Ziller 2001;Nunes et al 2018).…”

Biological invasions are considered one of the greatest threats to global biodiversity. In addition, they cause substantial economic impacts. However, studies about the subject in Brazil are still scarce. The aim of the present study was to prepare an inventory of non-native flora with invasive potential from Sergipe, Brazil. The inventory was carried out along the entire length of the sites. The species with potential invaders were grouped according to the biome/ecosystem and classified according to their habit and origin. Eighty-five species with invasive potential were sampled, 43 in the Caatinga, 75 in the Atlantic Forest, 36 in Sandbank and 22 in Mangrove. From these species, 17 were inventoried in all the biomes/ecosystems and 36 were observed in only one of them, six in the Caatinga, 27 in the Atlantic Forest and three in Sandbank. The number of potentially-invasive species sampled in Sergipe is alarming. The present study showed nearly twice the species listed by other authors for the entire northeast Brazil. This high number of taxa may be a consequence of facilitating the transfer of these species and the conservation conditions of the ecosystems studied in Sergipe. Another very worrying factor is that many of the species sampled are extremely aggressive and cause a series of impacts.
