1. Novelties in Brazilian Waltheria L. (Byttnerioideae, Malvaceae): two new species and one re-establishment
ABSTRACT This work validates two Waltheria species endemic to campo rupestre with complete descriptions, illustrations, updated geographical distributions and comments on taxonomic affinities. Waltheria biribiriensis and Waltheria terminans are restricted to the Southern Espinhaço Province in eastern South America, occurring on mountain tops where campo rup

2. Phenology and dispersal syndromes of woody species in deciduous forest fragments of the Pantanal in Mato Grosso do Sul State, Brazil
ABSTRACT We analyzed the phenological responses of shrub-tree species of lowland deciduous (LDF) and submontane deciduous (SFD) forests in the Pantanal, and assessed their relationships with climatic factors at the community level and with strategies for seed dispersal. Vegetative and reproductive phenophases of 50 tree-shrub species were monitored monthly (

3. Distribution of gall-inducing arthropods in areas of deciduous seasonal forest of Parque da Sapucaia (Montes Claros, MG, Brazil): effects of anthropization, vegetation structure and seasonality
Abstract In the present study, we inventoried gall-inducing arthropod species and evaluated the effects of habitat anthropization, vegetation structure and seasonality on this group in areas of deciduous seasonal forest of Parque da Sapucaia, Montes Claros, MG, Brazil. The gall-inducing fauna was sampled between April 2017 and February 2018 from 20 plots dis

4. Spatiotemporal ecology of two Neotropical herbivorous mammals
Abstract On this study, we used camera traps in a Semi deciduous Seasonal Forest, northeast of Brazil, to estimate the frequencies of occurrence of two Neotropical herbivorous mammals: the spotted paca (Cuniculus paca) and the tapeti (Sylvilagus brasiliensis), analyzing their seasonal variations of spatial distribution. We also characterized the activity pat

5. MORPHOLOGICAL AND PHYSIOLOGICAL PLASTICITY OF SAPLINGS OF Cabralea canjerana (Vell.) MART. IN DIFFERENT LIGHT CONDITIONS
RESUMO Este trabalho foi realizado com o objetivo de verificar a plasticidade dos folíolos de plantas jovens de Cabralea canjerana e sua capacidade de adaptação a diferentes ambientes luminosos por meio de características morfológicas e fisiológicas. Para isto, foram selecionadas 12 plantas de fragmento de Floresta Estacional Decidual secundário, send

6. Edaphic Macrofauna as Indicator of Edge Effect in Semi-deciduous Forest Fragments
ABSTRACT The aim of this study was to evaluate the edge effect using the macrofauna community of the soil as indicator in three fragments of Semi-deciduous Seasonal Forest in the city of Vitória da Conquista, Bahia, Brazil. Three sampling ranges denominated edge, transition and interior were delimited in each fragment. The macrofauna community was sampled

7. Litterfall Deposition and Decomposition in an Atlantic Forest in Southern Goiás
ABSTRACT Brazilian biomes have been severely threatened and their conservation depends on the knowledge of intrinsic ecological processes and correct phytophysiognomy identification of legal protection purposes. Litterfall deposition and decomposition patterns associated with taxonomic composition, climate, soil and relief can be considered important tools

8. Ecophysiology of deciduous plants grown at different densities in the semiarid region of Brazil
Physiological differences in the Cordia oncocalyx tree growing at different densities in two distinct areas were investigated. An agrosilvopastoral system (AGP) and a secondary forest (SF) were studied. Under both types of land-use, C. oncocalyx presented a relative frequency of approximately 50%, and absolute densities of 670 and 80 individuals per hectare,

9. Gradientes edáficos e sua relação com as fitofisionomias do semi-árido meridional brasileiro / Edaphic gradients and their relationship with the vegetation types of semi-arid southern Brazil
The semi-arid region in Brazil represents a significant territorial extension, where the climate is markedly seasonal, with low rainfall, high evapotranspiration and higher temperatures. Its southern portion comprises the northern boundary between the states of Minas Gerais and Bahia. This region is dominated by dry forest vegetation type, however, different

10. Drought resistance in seedlings tree species of semideciduous tropical forest / Resistência à seca em plântulas de espécies arbóreas da floresta estacional semidecídua
The rainfall is high in tropical forests, but there is great variation in water availability to plants. On a local scale, this availability may vary depending on the location of individuals in gaps, their position in the landscape and soil composition. On a regional scale, variations related to the volume and distribution of rainfall, coupled with seasonal c

11. Population ecology of small rodents and marsupials in a semi-deciduous tropical forest of the southeast Pantanal, Brazil
The Pantanal is a South American biome characterized by extensive plains and stark environmental seasonality. Several habitats are subject to annual flooding, forcing small mammal species to aggregate in dry forest patches, which most likely influences their population dynamics and life history strategies. In order to investigate the seasonal influence on th

12. Seasonal variation in the maximum rate of leaf gas exchange of canopy and understory tree species in an Amazonian semi-deciduous forest
Leaf gas exchange, water potential, and specific leaf area of two tropical semi-deciduous tree species, Brosimum lactescens S. Moore and Tovomita schomburgkii Planch & Triana, were quantified to establish how these properties were affected by seasonal variations in rainfall and leaf canopy position. The study was conducted at a site near Sinop Mato Grosso, B
