“…A similar event was observed in Dyckia excelsa , a typical species from ironstone outcrops, studied in central‐western Brazil (Corumbá), when the highest percentage of flowering was verified in the dry season, although the species has been reported as subannual (Lenzi & Paggi, 2020). Rainfall is widely recognized as one of the most important environmental variables to trigger phenological events, such as flowering (Arruda et al, 2021; Borchert, 1983; Morellato et al, 2013; Morellato & Leitão‐Filho, 1990; Opler et al, 1976), and to influence the duration and synchronicity of this phenophase within individuals of a given species (Opler et al, 1976). Flowering during the rainy season is known for the majority of herbaceous and shrubby species in tropical seasonal environments (Belo et al, 2013; Rathcke & Lacey, 1985), such as the cangas in Carajás, which has a period of drought under strong evaporative demand due to high temperature, radiation, and poorly and superficially undeveloped soil cover (Skirycz et al, 2014).…”

Flowering phenology of herbaceous species was limited to the rainy season in cangas of Iron Quadrangle in Minas Gerais, Southeast Brazil as well (Arruda et al, 2021).…”

Amazon ironstone outcrops vegetation, or canga, is a remarkable environment in which the plants are adapted to peculiar circumstances. Knowledge regarding different aspects of this ecosystem remains modest, including necessary insights for its conservation and recovery, such as the reproductive phenology of priority species that form the plant community. This study aimed to monitor the reproductive phenology of critical native species that are categorized as rare, endemic, and/or threatened in the canga of the Amazon Rainforest, in Pará, Brazil. During February 2016 and May 2017, eleven species were evaluated regarding the presence or absence of flowering and fruiting phenophases, and these were associated with environmental variables. Phenological data were evaluated through circular statistical analysis. All studied species flowered and produced fruit during the monitoring period. The evaluated species have an annual reproductive cycle marked by seasonality and flowering peaks between March and April, during the wet season, and fruiting peaks during May, at the beginning of the dry season. The best period for collecting ripe seeds, a primary tool for the restoration of degraded areas, is June. Water availability may be essential for the establishment of annual plants and to induce flowering in both annual and perennial species. The reproductive phenophases of the studied species are concentrated within a short period and are synchronized, which may increase the possibility of cross‐pollination and minimize flower and seed predation. We discuss the challenges in including annual plants and the importance of having them and perennial species in conservation and restoration of degraded areas projects.

“…Compared with buffered understory herbaceous plants, woody plants are more directly vulnerable to climate change [67]. The pattern of woody plant diversity was more impacted by the urban heat island effect, in both native and non-native species [68,69]. According to certain research, the composition of woody plants often reflects more strongly past urban land use, and as woody flora is "catching up" with the current urban disturbance, it is more directly linked to urban environmental conditions.…”

Urbanization induces rapid plant environmental modifications, leading to alterations in plant diversity distribution patterns and plant homogenization. However, how plant diversity is distributed along urbanization gradients in regional urban agglomerations and its relationship with environmental factors are not well defined. In three nearby Henan Province Chinese cities—Zhengzhou, Kaifeng, and Zhongmu—along an urbanization gradient, the distribution pattern of plant diversity was quantified. Both native and non-native plants found in urban green spaces were taken into consideration. A total of 176 plant quadrats were selected and separated into three urbanization gradient types using space-constrained hierarchical clustering: urban core, urban suburb, and urban outskirt. Polynomial fitting was used to characterize the spatial distribution patterns of plants along the urbanization gradient, and Pearson correlation and the Mantel test were employed to examine the effects of environmental factors, including longitude, latitude, altitude, distance from the urban center, temperature, and illumination, on plant diversity. A total of 313 vascular plant species, comprising 137 woody species and 176 herbaceous species, were examined. Along the three urbanization gradients, remarkable variations in plant diversity for woody and herbaceous species were observed. The spatial patterns of plant diversity were consistent across cities, whereas woody plants and herbaceous plants displayed the opposite behavior. Distance to the city center and temperature were the most substantial environmental effect factors for the diversity of woody plants, whereas light factors had a major impact on herbaceous plants. These findings show different life-type plants are affected differently by urbanization, and they offer managers and planners a recommendation for increasing urban plant diversity by executing various interventions throughout the urban gradient.
