    Abstract Bamboos are important components of tropical and temperate forests, being able to provide essential ecosystem services such as carbon sequestration and soil erosion control. However, when canopy openings or other local disturbance events occur, bamboos can behave as opportunistic species, expressing high dominance in the understorey of forests, leading to changes in their structure and functioning. This study described the interactions between the presence of bamboo (Merostachys sp.) and the native tree community parameters (species richness, Shannon diversity index, functional diversity indices, and CWM values) in an Atlantic semideciduous forest, and how these interactions change between the two height classes of the community (small and large trees). We sampled all bamboo culms and living and standing dead trees with a diameter at breast height (DBH) ≥ 5 cm in 30 plots of 20 × 10 m. We found that the high density of native bamboo Merostachys sp. is associated with a decrease in tree density and basal area, and that bamboo density is differently associated with large and small trees. For the small trees, bamboo was negatively related to tree density, and positively related to the dominance of species with lower wood density and higher SLA. For the large trees, bamboo is negatively related to tree basal area. Besides that, plots with higher bamboo density have lower species richness and functional diversity possible due to strong environmental filtering that allows the dominance of acquisitive species. These acquisitive species invest in fast-growth but have a short lifespan, leading to high biomass mortality and lower standing biomass, reducing forests' carbon stocks over time. Studies on a large-scale and experiments that take into account time before and after Merostachys’s colonization are required in order to better understand the associations between bamboo presence and forest parameters.

    Abstract Knowledge about the effects of fire on tree communities of Araucaria forests (AF) is scarce, although this physiognomy is among the most threatened ones in the entire Brazilian hotspot Atlantic Forest. With this study, we sought to answer the following questions: After three years of the fire, how has the soil of this forest remnant been recovering? Are fires in the AF able to change the structure, composition and species richness of tree community? The survey was carried out in a remnant of AF in an integral protected area in Brazil. Two areas were selected, one that has no fire history in the last 30 years (unburned) and another that burned recently. In each area 25 permanent plots of 20 × 10 m were allocated and all shrub-tree vegetation with DBH ≥ 4.8 cm was sampled. Our initial expectations were largely refuted, since we found no differences between the two areas in composition and richness of tree species and in most soil environmental variables, but only in the community structure. The majority of the dead individuals were concentrated in the smallest diameter classes (DBH < 9.8 cm). The only soil environmental variables that presented differences were pH and organic matter. Our study shows that the AF presents a significant resistance against forest fires, probably due to the evolutionary history of this physiognomy with fire. Nevertheless, several individuals died, so it is also important to highlight that preventive measures against fires are always relevant for conservation of this endangered physiognomy.

    Abstract Urbanization leads to strong modifications of landscape structure and ecosystem functioning, and urban areas are spreading rapidly. The aim of this study was to investigate how phylogenetic diversity and composition of tree species are affected by urbanization itself and land-use history. We found that species richness, rarefied species richness and phylogenetic diversity are all affected by the land-use history of urban forests. Indeed, forests that regenerated from cropland, and particularly those regenerated from denuded landscapes, showed strong phylogenetic clustering, which was also related to their high perimeter-area ratio. Our analyses of phylogenetic composition show that urban forests without land-use history are compositionally indistinguishable from mature, non-urban forests. These two forest types house a diversity of evolutionary lineages and no specific lineage is a strong indicator of these forest types. In contrast, the two urban forest types with anthropogenic land-use history have a few, distinct lineages that are strongly associated with each of them, respectively. Overall, our results suggest that urban forests without previous land-use can house substantial amounts of angiosperm evolutionary diversity, which highlights the importance of preserving natural forest fragments as cities expand. This study highlights the substantial value of tropical urban forests and the importance of considering information on land-use history, even when studying urban environments.

    Abstract With urbanisation rapidly transforming our world, a better understanding of how urban ecosystems can contribute to biodiversity conservation is urgently needed. Here, we investigated the functional composition and diversity of plant assemblages in different types of urban forests with the intent to predict the stability of the functions provided by these forests through the functional redundancy and response diversity of species. For this, we used data from non-urban mature forests, remnant urban forests, urban forests regenerated from croplands and urban forests regenerated from soil denudation, all located in the Brazilian Atlantic Forest. Our results showed that species functional composition shifted among urban and non-urban forests. However, functional diversity was lost only in urban forests with some previous use, indicating that the natural regeneration of urban forests after previous land use results in functionally poor forests. Urban forests regenerated from soil denudation (more intense disturbance) had a lower functional diversity. Conversely, urban forests regenerated from cropland (less intense disturbance) showed only a reduction in the number of functions provided. Our analysis also revealed the reduced functional redundancy and response diversity of urban forests with previous land use, which may indicate a greater vulnerability of the functions provided by these forests. Thus, we emphasise in this study the importance of land use history for decision making in urban forest conservation policies and highlight the crucial role of natural remnant urban forests as reservoirs of functional diversity and stability in highly degraded and fragmented landscapes.

    Abstract Understanding the relationships between Coffea arabica L. and the native tree community of secondary forests regrowing after the abandonment of coffee plantations is important because, as a non-native species in the Neotropics, coffee can outcompete native species, reducing diversity and forests ecosystem services. We aimed to answer three questions: 1) Does coffee regeneration in secondary forests differ between shaded and unshaded abandoned plantations?; 2) How is coffee basal area related to structural attributes, species diversity and composition of the native community?; and 3) Do the relationships between coffee and native community differ between tree and sapling components? We sampled the tree and sapling components in a seasonal tropical dry forest that were previously used as shaded and unshaded coffee plantations. Coffee was the most important species in the sapling component of shaded systems, but was almost absent in unshaded ones. Coffee basal area was negatively related with the native density and absolute species richness of the sapling component; and was negatively related with tree density, and positively related with the percentage of pioneer individuals of the native tree component. Our results indicate that coffee persists in secondary forest communities even after more than 70 years of shaded-coffee plantations were abandoned, potentially reducing density and diversity of native species. Despite limitations, which hinder more general conclusions on coffee invasiveness in Brazilian secondary tropical forests, our results indicate that coffee is a strong competitor in the studied secondary forests and provide important insights for future research on this topic.

    Abstract O objetivo deste trabalho foi verificar as diferenças nas proporções das síndromes de dispersão de propágulos de espécies arbóreas entre florestas ombrófilas submontanas secundárias e preservadas no Estado do Rio de Janeiro. Foram utilizadas listas de espécies de sete florestas secundárias e cinco preservadas. Partiu-se da hipótese de que as florestas secundárias apresentariam menor riqueza e densidade de espécies arbóreas com síndrome de dispersão biótica (zoocoria). As médias das proporções de árvores com síndrome de dispersão biótica entre florestas secundárias e preservadas foram comparadas pelo teste U. Apesar de preponderarem em ambas, florestas secundárias e preservadas diferiram significativamente em riqueza e densidade de espécies com dispersão biótica (P < 0,01). Essas proporções foram menores nas florestas secundárias, corroborando essa hipótese. As florestas secundárias também apresentaram menor densidade de espécies zoocóricas pertencentes a famílias dispersadas por grandes vertebrados frugívoros (Lauraceae, Myrtaceae e Sapotaceae). Futuras práticas de manejo e conservação nessas florestas secundárias devem incorporar as interações plantas-dispersores, devido aos riscos nos processos de regeneração sem a presença da fauna dispersora adequada.

    Abstract O objetivo deste trabalho foi avaliar a estrutura diamétrica arbórea de um remanescente de Floresta Atlântica Submontana no Município de Silva Jardim, RJ. Foram utilizadas 20 parcelas de 100 x 5 m, em que todas as árvores com DAP > 5 cm foram amostradas. A estrutura diamétrica foi analisada em toda a comunidade e nas principais populações (determinadas segundo o VI), a partir de histogramas com intervalos de classes definidos pela fórmula de Spiegel. A análise também considerou os grupos sucessionais das espécies (pioneiras: PI; secundárias iniciais: SI; e secundárias tardias: ST). As curvas (J-reverso) e valores do quociente "q" indicaram ausência de problemas de regeneração das principais populações, a maioria de espécies SI. Entretanto, foi observada tendência de saída de algumas das principais populações de ST (ex. Plathymenia foliolosa e Euterpe edulis), paralelamente à entrada de outras SI. Os resultados complementam as análises florísticas desenvolvidas anteriormente no remanescente, o que indica que a estrutura diamétrica também foi alterada pela fragmentação e pelas perturbações antrópicas pretéritas. Ações coibindo novas perturbações e o enriquecimento através do plantio de mudas das espécies mais afetadas são urgentes, visando à recuperação da qualidade ambiental desse remanescente.

    Abstract Estudos florísticos vêm apontando a região da bacia do rio São João, no Estado do Rio de Janeiro, como detentora de uma riqueza e diversidade de espécies arbóreas particularmente altas. Entretanto, tais afirmativas são baseadas em estudos locais, não existindo ainda uma análise de sua flora arbórea em nível regional. A partir da compilação de inventários florísticos e fitossociológicos de 20 trechos de floresta ombrófila de baixada (30-300 m), o presente trabalho aborda a composição, riqueza e heterogeneidade da flora arbórea da bacia do rio São João. A compilação incluiu apenas as árvores com DAP > 2,5 cm, que foram identificadas em nível específico. A amostra da flora arbórea totalizou 460 espécies, 231 gêneros e 62 famílias. Estes números reafirmam que a região é realmente detentora de uma flora arbórea com alta diversidade, inclusive com diversas espécies raras ou vulneráveis à extinção, podendo ser considerada como uma das mais ricas entre as de Floresta Atlântica do Sudeste brasileiro. Análises multivariadas detectaram uma alta heterogeneidade florística entre os fragmentos florestais, contribuindo na elevada riqueza regional encontrada. Os padrões de similaridade sugerem que a principal fonte desta heterogeneidade provém dos diferentes estados de conservação das áreas.

    Abstract O presente trabalho teve por objetivo avaliar a composição florística arbórea de um trecho de Floresta Atlântica submontana na região de Imbaú, Silva Jardim, RJ. Esta região formava um contínuo florestal que foi fragmentado há mais de 50 anos por práticas agropecuárias. Cinco fragmentos foram selecionados e em cada um deles foram alocadas quatro parcelas de 100x5 m. Todas as árvores vivas com DAP > 5 cm foram amostradas e identificadas. No hectare amostrado foram encontradas 161 espécies distribuídas por 39 famílias. A similaridade florística entre os fragmentos foi alta, com índice de Morisita variando de 0,36 a 0,79. As famílias Leguminosae, Lauraceae e Rubiaceae apresentaram a maior riqueza de espécies. A comparação florística com uma floresta madura da região indicou forte decréscimo na riqueza de espécies que, juntamente com a elevada densidade de espécies secundárias iniciais, indicam que estas matas se encontram em estádio sucessional secundário. Analisando a similaridade florística entre a região de Imbaú e outras 17 florestas do Rio de Janeiro, observou-se maior similaridade com as florestas submontanas mais próximas geograficamente. Devido ao avançado processo de fragmentação e à importância ecológica destes fragmentos para a manutenção da flora e fauna, sugere-se que a região de Imbaú deva ser prioritária em programas de conservação e manejo de áreas de Mata Atlântica.

    Abstract AIM: Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) and in terms of responses to climate change. We quantified global patterns of tree palm relative abundance to help improve understanding of tropical forests and reduce uncertainty about these ecosystems under climate change. LOCATION: Tropical and subtropical moist forests. TIME PERIOD: Current. MAJOR TAXA STUDIED: Palms (Arecaceae). METHODS: We assembled a pantropical dataset of 2,548 forest plots (covering 1,191 ha) and quantified tree palm (i.e., ≥10 cm diameter at breast height) abundance relative to co‐occurring non‐palm trees. We compared the relative abundance of tree palms across biogeographical realms and tested for associations with palaeoclimate stability, current climate, edaphic conditions and metrics of forest structure. RESULTS: On average, the relative abundance of tree palms was more than five times larger between Neotropical locations and other biogeographical realms. Tree palms were absent in most locations outside the Neotropics but present in >80% of Neotropical locations. The relative abundance of tree palms was more strongly associated with local conditions (e.g., higher mean annual precipitation, lower soil fertility, shallower water table and lower plot mean wood density) than metrics of long‐term climate stability. Life‐form diversity also influenced the patterns; palm assemblages outside the Neotropics comprise many non‐tree (e.g., climbing) palms. Finally, we show that tree palms can influence estimates of above‐ground biomass, but the magnitude and direction of the effect require additional work. CONCLUSIONS: Tree palms are not only quintessentially tropical, but they are also overwhelmingly Neotropical. Future work to understand the contributions of tree palms to biomass estimates and carbon cycling will be particularly crucial in Neotropical forests.
