“…The notable presence of synanthropic species is associated with the fact that many aquatic environments are close to anthropogenic environments, such as cities, areas of animal husbandry, generally linked to pastures, which may have favored a high number of species of Cyperaceae, Poaceae, Asteraceae and Fabaceae (Henry-Silva, Moura & Dantas, 2010;Xavier, Araújo, Nascimento & Pereira, 2012;Pivari, Viana & Leite, 2013;Machado-Filho, Couto, Bezerra & Melo, 2015;Sabino, Araújo, Cotarelli, Siqueira-Filho & Campelo, 2015).…”

We present a list of aquatic and wetland plant species from the state of Paraíba, Brazil, based on the collections deposited in national and international herbaria. We identified 290 species belonging to 61 families. The checklist includes habit, localities of the collections in the state of Paraíba, and geographic distribution of each species. The amphibious habit was the most prevalent and the Sertão (semiarid inland region) was the region with the greatest collection effort. New occurrences have been registered for the state (14 species). Although our data reveal a high plant richness, we relate this richness to increased field expeditions.

“…procumbens, a species belonging to the Asteraceae family. This plant family are frequent colonizers of anthropized areas with floral strategies that can optimize cross-pollination (Machado-Filho et al, 2015). According to Mani and Saravanan (1999), species of the Asteraceae family are of great ecological importance, as their inflorescences are visited by several animals that seek nectar and pollen throughout the year.…”

Urbanization restricts native vegetation to small fragments surrounded by paved areas, grasses and degraded areas that strongly affects several biotic communities, including pollinator populations, which are not only greatly affected, but are also declining in several parts of the world. Bees are considered to be the main organisms to perform pollination, as they need to visit a great number of flowers daily to satisfy their individual food needs, their offspring and their colony, since they depend on floral resources at all stages of their life. Thus, the aim of this study was to verify the effectiveness of urban parks as refuges for bee species, having its veracity as a hypothesis. It was considered to evaluate the diversity of bees and their foraging activities in plant species in two urban parks over a year located in the city of Dourados-MS/Brazil. Sampling was performed every two weeks, from 8:00 a.m. to 4:00 p.m. for 13 months, from 2019 to 2020. For this purpose, active samplings were carried out with an aerial entomological net. Bee species were found distributed in 5 families: Apidae, Halictidae, Colletidae, Megachilidae and Andrenidae. Apis mellifera was the most abundant species followed by Trigona spinipes. Considering the two parks, 34 species of bees visiting 33 plant species were sampled. Results suggest that urban parks represent a significant area for maintenance of bee populations in the city of Dourados - MS, protecting a very diverse fauna, confirming the hypothesis that urban parks represent relevant and functional areas for bees, helping in the diversity maintenance of these pollinating organisms.

“…Apesar das plantas ruderais ocuparem tanto zonas rurais quanto urbanas, o termo "ruderal" é mais comumente utilizado para as assembleias de plantas associadas aos ambientes tipicamente antropizados da malha urbana (MACHADO-FILHO et al, 2015). Nos agrossistemas, o termo mais comumente utilizado ainda é "planta daninha" (LORENZI, 2008;2014).…”

A urbanização é um preditor da riqueza de espécies, logo, a vegetação nessas áreas pode ser mais homogênea, pela presença de plantas generalistas e com dispersão eficiente, havendo co-ocorrência das mesmas espécies. Por outro lado, áreas urbanas poderiam ser mais heterogêneas, dada a natureza de micro-habitats disponíveis para a ocupação da vegetação pioneira diversa. Com isso, este trabalho pesquisou artigos científicos no Google Acadêmico, listando espécies ruderais no Brasil com respectivo hábito, síndrome de dispersão, distribuição geográfica e origem biogeográfica. As áreas analisadas foram comparadas entre si para verificar o grau de similaridade florística e os percentuais de similaridade foram comparados com a distância geográfica entre as respectivas áreas. Análises de correlação entre a riqueza das áreas e variáveis abióticas e a taxa de urbanização das áreas também foram avaliadas. Com isso, foram identificados um total de 14 artigos, sumarizando 1.006 espécies, 549 gêneros e 123 famílias. Nesse cenário, Asteraceae e Poaceae foram as famílias com maior ocorrência. Houve maior registro de plantas herbáceas, com forma de crescimento camefítico, dispersão autocórica, predominando espécies originárias da América do Sul. Dentre as espécies, 43% são exóticas, sendo a Ásia o continente de maior contribuição. As variáveis abióticas e a taxa de urbanização exibiram baixo poder de explicação e de correlação sobre a riqueza das áreas. A análise de similaridade, indicou maior heterogeneidade entre as floras, quando vistas do ponto de vista continental, mas há tendência à homogeneização dessas assembleias quando vistas dentro de complexos macroclimáticos. A análise de regressão indicou que à medida que as áreas se distanciam há diminuição da similaridade de forma significativa. Pode-se concluir que as floras de áreas antropizadas urbanas do Brasil tendem a ser mais heterogêneas entre si. Palavras-chave: fitogeografia; florística; similaridade; urbanização. Trends in the richness and composition of ruderal species: Floristic homogenization or heterogenization? ABSTRACT: Urbanization predicts species richness; therefore, the vegetation in these areas may be more homogeneous due to generalist plants with efficient dispersion and the co-occurrence of the same species. On the other hand, urban areas could be more heterogeneous, given the nature of microhabitats available for the occupation of diverse pioneer vegetation. This work searched for scientific articles in Google Scholar, listing ruderal species in Brazil with their respective habit, dispersion syndrome, geographic distribution and biogeographical origin. The analyzed areas were compared to verify the degree of floristic similarity, and the similarity percentages were compared with the geographic distance between the respective areas. Correlation analyses between the richness of the areas and abiotic variables and the rate of urbanization of the areas were also evaluated. With this, 14 articles were identified, summarizing 1,006 species, 549 genera and 123 families. In this scenario, Asteraceae and Poaceae were the most representative families. Herbaceous plants were predominant, with camephytic growth form, autochoric dispersion, and predominating species originating in South America. Among the species, 43% are exotic, with Asia being the predominant continent in this contribution. The abiotic variables and the urbanization rate showed a low power of explanation and correlation on the richness of the areas. The similarity analysis indicated greater heterogeneity between the floras when seen from the continental point of view. Still, there is a tendency towards homogenization of these assemblages when seen within macroclimatic complexes. The regression analysis indicated that there is a significant decrease in similarity as the areas move away. It can be concluded that the floras of urban anthropized areas in Brazil tend to be more heterogeneous among themselves. Keywords: phytogeography; floristics; similarity; urbanization.
