Phytosociology of the caatinga in Floresta Nacional de Açu, Rio Grande do Norte...
Paiva, Carla Daniela Guedes; Moro, Marcelo Freire; Sousa, Leandro de Oliveira Furtado de; Baldauf, CristinaThe semiarid region of Rio Grande do Norte State in the Northeast region of Brazil can be divided into two main geoenvironmental units: Sertaneja Depression and Potiguar Sedimentary Basin. Although the flora of sandy sedimentary basins is usually different from that of crystalline terrains, part of the Potiguar Basin has stony paleo-alluvial deposits, with rolled pebbles, imposing different edaphic conditions t...
A Phytogeographical Metaanalysis of the Semiarid Caatinga Domain in Brazil
Moro, Marcelo Freire; Lughadha, Eimear Nic; Araújo, Francisca Soares de; Martins, Fernando RobertoSeasonally Dry Tropical Plant Formations (SDTFs) are among the most threatened biomes worldwide. Nevertheless, they have received less scientific attention than rainforests or savannas. One such SDTF, the Caatinga Phytogeographic Domain (CPD), is the largest semiarid tropical ecoregion in South America. Earlier floristic studies of the Caatinga flora discerned two floristic groups in the CPD, in terrains of cry...
The role of edaphic environment and climate in structuring phylogenetic pattern...
Moro, Marcelo Freire; Silva, Igor Aurélio; Araújo, Francisca Soares de; Lughadha, Eimear Nic; Meagher, Thomas R.; Martins, Fernando RobertoSeasonally dry tropical plant formations (SDTF) are likely to exhibit phylogenetic clustering owing to niche conservatism driven by a strong environmental filter (water stress), but heterogeneous edaphic environments and life histories may result in heterogeneity in degree of phylogenetic clustering. We investigated phylogenetic patterns across ecological gradients related to water availability (edaphic environ...
How much importance is given to native plants in cities’ treescape? A case stud...
Moro, Marcelo Freire; Westerkamp, Christian; Araújo, Francisca Soares deEven though Brazil is a mega-diverse country, many Brazilian cities prioritize exotic plants in their treescapes. Aiming to evaluate how much the treescape in Fortaleza (the fifth largest city in Brazil) is aligned with the policy of valorization of native biodiversity, we sampled street and backyard trees surrounding one of the few vegetation fragments of the city, which is an area considered a priority for co...
Naturalization and potential impact of the exotic tree Azadirachta indica A.Jus...
Moro, Marcelo Freire; Westerkamp, Christian; Martins, Fernando RobertoInvasive species are among the leading causes of biodiversity loss on the planet, and some species that have become invasive were intentionally introduced for ornamental or commercial purposes. Azadirachta indica A.Juss. (Indian neem) is an exotic species that is widely cultivated in the northeastern region of Brazil, both in plantations and as an ornamental or shade tree, where it has reached reproductive phas...
O complexo vegetacional da zona Litorânea no Ceará: Pecém, São Gonçalo do Amarante
Castro, Antônio Sérgio Farias; Moro, Marcelo Freire; Menezes, Marcelo Oliveira Teles deO Litoral Setentrional do Nordeste (LSN) por sua localização geográfica apresenta clima mais quente e seco do que na costa leste do Brasil. Por sua proximidade com a caatinga e o cerrado, o LSN permite a co-existência de espécies destes Domínios conjuntamente com espécies de restinga, em diferentes formações, constituindo um Complexo Vegetacional. Apesar da grande importância ecológica e botânica deste ecótono,...
Alienígenas na sala: o que fazer com espécies exóticas em trabalhos de taxonomi...
Moro, Marcelo Freire; Souza, Vinicius Castro; Oliveira Filho, Ary Teixeira de(Aliens in the room: what to do with exotic species in taxonomic, floristic and phytosociological studies?): The ever- -growing presence of exotic organisms (many of which become invasive) throughout the planet has led to the emergence of biological invasions as a field of study within ecology. To enable communication between scientists in this field, a terminology has developed. However, this terminology has b...
Composição florística e estrutura de um fragmento de vegetação savânica sobre o...
Moro, Marcelo Freire; Castro, Antônio Sérgio Farias; Cavalcante, Francisca SoaresUrban growth promotes reduction in the vegetation cover, introduction of exotic species and has serious implications for biological conservation. In the urban area of Fortaleza, Ceará state, a vegetation fragment with savannic physiognomy (24 ha – 3º47’55”S and 38º29’10”W) was sampled for a floristic survey and had 1 ha subjected to a phytosociological inventory. The floristic list of the fragment, considered a...
The alien street trees of Fortaleza (NE Brazil): qualitative observations and t...
Moro, Marcelo Freire; Westerkamp, ChristianPublic tree planting is important for cities. It produces shadow, brings well-being for humans, and supports the urban fauna. But the cultivation of exotic plants can also be responsible for dissemination of invasive species. This paper aims to evaluate public tree planting in Fortaleza, Ceará state, in northeastern Brazil. From 2005 to 2009, qualitative observations on tree composition in the city were made. I...
Plantas dos espaços livres da Reitoria da Universidade de Fortaleza (UNIFOR), C...
Castro, Antônio Sérgio Farias; Moro, Marcelo Freire; Rocha, Fernanda Cláudia Lacerda(Plants from the open spaces of the rectory of the University of Fortaleza (UNIFOR), Ceará, Brasil). Cultivated plants may work as an educational tool, creating in humans a feeling of affection with nature, which may increase public’s support to conservation programs. However, most cultivated plants in Brazilian cities are exotics, reducing the role of street trees and gardens in environmental education. This s...
