1. Impact of environmental changes on Dermatology,
Abstract Urbanization, pollution and the modification of natural landscapes are characteristics of modern society, where the change in human relations with the environment and the impact on biodiversity are environmental determinants that affect the health-disease relationship. The skin is an organ that has a strong interface with the environment and, theref

2. Niche differentiation between a native and an invasive species of submersed macrophyte in a subtropical reservoir
ABSTRACT Submersed macrophytes have important ecological roles but non-native invasive species may affect biodiversity and water uses. We investigated the native macrophyte Egeria najas and the invasive Hydrilla verticillata and measured their maximum colonization depth and its relationship with Secchi disk depth, their biomass along the depth gradient and t

3. Conservation of species-rich subtropical grasslands: traditional management vs. legal conservation requirements in primary and secondary grasslands
ABSTRACT Land-use change is the main cause of biodiversity losses, and for grasslands includes changes in management. The last 10 years has seen afforestation of traditionally grazed grasslands increase considerably in the understudied Serra do Sudeste region of the Brazilian Pampa, turning the region into a mosaic of tree plantations, natural ecosystems (pa

4. Emerging hotspots of tree richness in Brazil
ABSTRACT We present a summary of floristic variation and distribution of richness of tree and tree-like taxa (i.e., freestanding plants that reach at least 3m in height) in Brazil. We investigated composition patterns throughout phytogeographic domains and vegetation types based on 698,490 occurrence records obtained from the NeoTropTree (NTT) database, and

5. Rediscovering a forgotten scientific collection in the Rio Grande do Norte State, Brazil: The herpetological collection of the zoologist José Santiago Lima-Verde
Resumo: O zoólogo Dr. José Santiago Lima-Verde (1945-2019) fez uma série de importantes contribuições para o campo da biologia animal no nordeste do Brasil, em particular através de sua pesquisa com serpentes. Enquanto professor da Escola Superior de Agricultura de Mossoró, atualmente Universidade Federal Rural do Semi-Árido, o Prof. Lima-Verde estab

6. The study of biotic interactions in the Brazilian Cerrado as a path to the conservation of biodiversity
Abstract: As a focus for conservation efforts, biodiversity has received increased attention in the last fifty years. Searching for patterns in biodiversity, researchers have suggested studies including: ecological communities, cladistics classifications, hierarchical compositions of different levels of organization, and groups of taxonomically related speci

7. Epiphyte-phorophyte relationships: assessing the differences between Seasonal Semideciduous and Swamp Forests in Southeastern Brazil1
RESUMO As epífitas vasculares são responsáveis por uma parcela considerável da biodiversidade tropical; no entanto, suas relações com os forófitos entre diferentes tipos de vegetação em que ocorrem ainda são pouco compreendidas. Neste trabalho, objetivamos avaliar a presença, a abundância, a distribuição vertical e a categoria ecológica (holoe

8. Community structure and tree diversity in a subtropical forest in southern Brazil
Resumo: Variações ambientais locais e regionais levam à composição de espécies diferentes e áreas de transições. Um exemplo é a floresta com araucária e a floresta estacional no sul do Brasil. Nossos objetivos foram (1) descrever a composição e estrutura da comunidade arbórea de uma floresta subtropical no sul do Brasil e (2) comparar as relaç

9. Genetic diversity and population structure of naturally rare Calibrachoa species with small distribution in southern Brazil
Abstract Calibrachoa is a South-American genus comprising 27 species, several considered endemic or rare; few were subjects in genetic studies. We attempted to generate new data about the phylogenetically related and rare species C. eglandulata, C. sendtneriana, C. serrulata, and C. spathulata concerning their genetic diversity and population structure, whic

10. Patterns of richness and distribution of Cactaceae in the Serra da Mantiqueira, Southeast Brazil, and implications for its conservation
Abstract This study aimed to analyze patterns of richness and distribution of Cactaceae in the Serra da Mantiqueira (SM), a mountain range located in Southeast Brazil, and assess its conservation status. We compiled distribution data from the literature and 16 herbaria and plotted it on a map divided into grid squares of 0.5°. Richness, collection effort an

11. Latin American scientific contribution to ecology
ABSTRACT Latin America embodies countries of special interest for ecological studies, given that areas with great value for biodiversity are located within their territories. This highlights the importance of an evaluation of ecological research in the Latin America region. We assessed the scientific participation of Latin American researchers in ecological

12. Eficiencia de las unidades de conservación definidas en la Reserva Natural Iberá (Argentina) en la protección de la diversidad de reptiles
ABSTRACT Owing to accelerated biodiversity loss caused by human activities, the protected areas (PAs) are the main response to mitigate this crisis. The Iberá Natural Reserve (INR) includes 13000 km2 of private and state lands, which contain wetland and upland areas with high biodiversity, endemism and significant populations of threatened species. In order
